▼ The incidence of autism has increased from an average of one in 88 to one in 110 (Center for Disease Control, 2010; ADDM Network, 2012). Autism spectrum disorders are an important health and educational problem affecting many areas of daily living, (CDC, 2012; Cermak, S., et al, 2010). Over 80 percent of children diagnosed with autism demonstrate
sensory modulation symptoms and related behaviors such as
sensory seeking,
sensory avoiding, self-stimulation, etc, (Kintwell, et al, 2011; Ben-Sasson, et al, 2009; Tomchek & Dunn, 2006).
There is some beginning evidence found in the literature that
sensory processing of children on the autism spectrum interferes with their daily routines (Nadon, et al, 2011; Stein, et al, 2011/2012; Schaff, et al, 2011), and there is a paucity of research which addresses the impact
sensory processing has on the daily routine of eating. This study will contribute to this expanding body of knowledge.
Eating difficulties are a frequent problem for children on the autism spectrum (Nadon, et al, 2011; Schreck & Williams, 2006) which impacts their physical health (Lukens & Linscheid, 2008), their functioning in the family (Schaff, et al, 2001) and their functioning in educational settings (Koenig & Rudney, 2010). This study assesses the differences in
sensory processing and eating problem behaviors between two groups of children, aged 5 -12 years, those identified on the autism spectrum (N=34) and those typically developing (N=34).
Data was collected through parent and child questionnaires that assessed
sensory processing and eating behaviors (BAMBI, Short
Sensory Profile,
Sensory Eating Checklist, and Touch Inventory for Elementary-Aged Children). Results of the t test, anovas and correlation analyses revealed statistically significant differences on all measures between both samples (p

▼ Individuals with Autism Spectrum Disorder (ASD) display deficits in social communication and repetitive and stereotyped behaviours, including atypical sensory behaviours. ASD cannot be diagnosed before 3 years old. However, earliest interventions are believed to provide the best outcomes. It is therefore necessary to evidence early markers of ASD. Many theorists argue that hypersensitivity to environmental stimulation leads to the development of ASD. The aim of the study was thus to investigate the relationship between early hypersensitivity and development of ASD-like symptoms. Auditory processing was assessed in 49 nine months old babies at low and high risk of developing ASD using electroencephalography. Two types of hypersensitivity were measured: the ability to discriminate subtle changes in sounds and responses to noise. Assessed ASD-like symptoms were atypical verbal and non-verbal communication skills and repetitive behaviours at 24 months old. Babies at high risk who developed typical language skills had increased ability to discriminate sounds, compared to babies at high risk with poor language skills and babies at low risk (i.e., with typical language skills). Hypersensitive sound discrimination might therefore help babies at high risk develop good language skills. The better the ability of babies at high risk was to discriminate sounds, the better their non-verbal communication skills at a later age. This relationship was not significantly different in babies at low risk, suggesting that the ability to discriminate sounds might be helpful in typical and atypical development of non-verbal communication skills. Babies at high risk who had enhanced responses to noise went on to develop repetitive behaviours. Repetitive behaviours might therefore help over-aroused babies to self soothe. The current study did not show a causal relationship between early hypersensitivity and development of ASD. Nevertheless, early markers of hypersensitivity could be used to index development of some ASD symptoms.

▼ Every second throughout life, cortical circuitry efficiently compresses and interprets huge volumes of incoming sensory information. This high fidelity sensory processing guides normal brain development and is essential for animals’ successful interaction with the environment. Low-level sensory perceptual disturbance is nearly ubiquitous in Autism Spectrum Disorder (ASD), but despite the potential to offer crucial insight into the abnormal development of higher brain function is poorly understood. Fragile X Syndrome (FXS) is the most common heritable cause of ASD. Previous studies in the Fmr1-KO mouse model of FXS report cell-intrinsic, synaptic and local connectivity abnormalities in the neuronal physiology of primary sensory cortices. This suggests that sensory perceptual dysfunction could emerge from interacting circuit-wide pathophysiology to impair neural adaptations that support high fidelity sensory information processing. However, there is little mechanistic consensus about how this might occur. To address this, in this thesis I use brain slice electrophysiology and computer modelling to provide a bottom-up description of how thalamocortical (TC) responses, the principal cortical input for ascending sensory information, are mis-interpreted in the somatosensory Layer 4 (L4) circuit in Fmr1-KOs at a crucial developmental transition to active sensory processing. Recruitment of intracortical L4 network activity could be atypically evoked by lower frequency thalamic stimulation in Fmr1-KO slices. Furthermore, profound alterations to single-cell and network response dynamics were observed, in particular loss of spike timing precision considered critical for sensory circuit performance. These network phenomena were supported by interacting single-cell and local circuitry pathophysiology, including hyperexcitable cortical neurons and temporally distorted feed forward and feedback inhibition. Together, these data demonstrate cortical hypersensitivity to TC inputs and abnormal recruitment of network activity in critical period Fmr1-KO somatosensory cortical circuits. The hyperresponsiveness of intracortical circuitry may underlie tactile hyperexcitability and distorted sensory perception in FXS patients. Interestingly, modelling suggests that many of the alterations of synaptic and neuronal function are compensatory, thus minimizing the impact of the genetic lesion. Thus, this study shows for the first time that circuit level dysfunction emerges in the Fmr1-KO mouse from an accumulation of effects at the synaptic and cellular level; however, it also highlights the challenge of understanding which of these changes are pathological and which are compensatory.

▼ Background: Very preterm infants (<30 weeks’ gestation) are unable to fully modulate extrauterine stressors because of their anatomic, chemical and physiologic immaturity and instability.1, 2 This places them at risk of multiple prenatal complications, including neuronal injury. During a time of rapid brain growth and organisation, very preterm infants are exposed to a sensory environment which is inconsistent with their sensory system maturation. This early exposure might affect the preterm infant’s later capacities to process and respond to future sensory stimuli, changing the nature of their early learning opportunities. The sensory processing capacities of very preterm infants might be an underlying contributor to the diverse range of neurodevelopmental deficits reported in preterm survivors. The first aim of this study was to examine the sensory profiles of infants born <30 weeks’ gestation at 24 months’ corrected age and compare them with published norms. The second aim was to explore the biological (gender, white matter abnormality) and environmental (length of stay, high social risk and home-based early intervention) predictors of sensory profiles. The third aim was to determine the relationship between sensory profiles and cognitive, language and motor development at 24 months’ corrected age.
Method: The sample included 115 infants born <30 weeks’ gestational age who were admitted to the Neonatal Intensive Care Units at The Royal Women’s and The Royal Children’s Hospital, Melbourne, during January 2005 and January 2007. Fifty percent of the cohort was randomly assigned to a home-based intervention program comprising of nine home visits by a physiotherapist and psychologist over the first 11 months’ of life. The program aimed to improve infant development (cognitive, motor and language), behavioural regulation, caregiver-child interactions and caregiver mental health. At 24 months' corrected age, sensory processing was examined using the Infant/Toddler Sensory Profile Questionnaire.3 The primary caregiver rated the frequency with which their infant(s) responded to various sensory experiences. Different responses reflect a child’s neurological threshold and self-regulation behaviour, and interact to present a sensory profile that consists of four patterns, Low Registration, Sensation Seeking, Sensory Sensitivity and Sensation Avoiding. Cognitive, language and motor development was also assessed at 24 months’ corrected age (blinded to group allocation or sensory profile scores) using the Bayley Scales of Infant and Toddler Development (3rd Ed). A two-sample t-test was conducted and reported the mean difference, 95% confidence interval and p-value between the preterm infant and published norms sensory profile raw scores. Regression analysis was used to explore the influence of biological and environmental factors on very preterm infant sensory profiles, as well as the relationships between sensory profiles and developmental outcomes at 24 months’ corrected age.

▼ The goal of this quantitative, descriptive pilot study was to identify the frequency of
sensory processing disorders (SPD) in preschool students who are preparing for the transition into kindergarten. The research also explored the relationship between preschool teachers' perspectives of challenging classroom behavior and parents' reports of
sensory processing in the home. Researchers distributed the
Sensory Processing Measure for Preschoolers (SPM-P) assessment to parents and a behavioral questionnaire to teachers in three northern California preschools. Thirty-two SPM-P assessments were distributed to parents and 15 (47%) were accurately completed and returned. Of this sample, 2 (13%) student scores on the SPM-P reflected SPD. The SPM-P assessments not returned by parents were categorized as non- SPD students. Based on this assumption, 6.2% of the children within the greater population of 32 demonstrated
sensory processing disorder. Results of the behavioral questionnaire found that teachers identified 3 or more maladaptive classroom behaviors for students who met the criteria for SPD. The research suggests that there may be a relationship between maladaptive classroom behavior and a child’s ability to process
sensory information. Thus, further education on
sensory processing and environmental adaptations that encourage positive participation in school may benefit teachers, parents, and children.

▼ Objectives. Most individuals with Autism Spectrum Disorder (ASD) experience
sensory deficits in their auditory
processing (Tomchek & Dunn, 2007). These deficits can further impact their ability to participate in their physical and social environments. One way to increase understanding of these deficits is through use of electroencephalography (EEG), which measures brain activity in real-time and is able to distinguish brain processes such as
sensory processing and the deficits that might be occurring during this process (Davies & Gavin, 2007). This study's purpose is to understand how
processing speed and ability to filter out irrelevant stimuli impacts adults with ASD compared to their neurotypical (NT) peers through measurements of latency of prominent brain activity following presentation of an auditory stimulus and
sensory gating. This study also analyzed how active and passive attention states impact
sensory gating and latency. Methods. 24 adults with autism (M = 23.3 years, SD = 3.8) and 24 neurotypical adults (M = 23.7 years, SD = 3.5) participated in this study. They completed a
sensory gating paradigm in both an active and a passive listening condition. In the active condition they were asked to press a button when they heard a single click, and in the passive condition they simply stared at a static image on a screen while the auditory stimuli were presented to them. Results. The results showed that there are no significantly different
sensory gating responses between the ASD and NT groups. Individuals with ASD had delayed
processing speed as measured through latency as early as 100 milliseconds following an auditory stimulus. Both groups experienced slower
processing in the passive condition starting at approximately 200 milliseconds post-stimulus onset. As expected, more gating was observed for both groups in the passive condition at early components, where-as the active condition - which required attention to the stimulus that is usually suppressed in this task - resulted in less gating. In the latest component analyzed, approximately 200 milliseconds post-stimulus, both groups showed more gating in the active attention state, which was the opposite of the expected results, and the possible reason for this unexpected result needs further exploration. Conclusions. These findings suggest that individuals with autism do not have deficits in the ability to filter out irrelevant stimuli, however, they are likely more impacted by delayed
processing speeds. Implications for practice include allowing more time to process auditory information for individuals with autism, and using compensatory strategies to influence neural
processing speeds and amount of gating in response to auditory stimuli through the use of activity demands to create either passive or active attention states.

▼ Individuals with attention-deficit/hyperactivity disorder (ADHD) have reported secondary symptoms such as speech problems, somatosensory impairments, and
sensory processing deficits. Current research efforts to assess these symptoms have focused on children with ADHD. The purpose of this study was to investigate the relationship of these secondary symptoms in adults with ADHD compared to age-matched controls. Twenty adults with ADHD and 20 age-matched adults without ADHD were recruited for this study. All participants provided a speech sample, completed bilateral lip and tongue somatosensory assessments, and completed the Adult/Adolescent
Sensory Profile (AASP). Differences between groups were assessed using independent t-tests. Although individuals with ADHD demonstrated increased reading time, decreased reading accuracy, and decreased tactile detection and discrimination abilities; none reached the level of significance. Adults with ADHD reported significantly more
sensory under- and over-responsivity behaviors. Correlational analyses were used to assess the relationship between reading time and accuracy, 2-pt discrimination, tactile detection and discrimination, and prevalence of
sensory under- and over-responsivity behaviors in adults with ADHD. Decreased two-point discrimination abilities in left tongue and right lip were correlated with the speech measures: passage time (r (40) = 0.333, p = .036) and passage errors made (r (40) = -0.317, p = .046), respectively.
Sensory over-responsivity was correlated with two of the somatosensory measures: tactile detection left tongue (r (37) = 0.341, p = .039) and tactile discrimination right tongue (r (37) = 0.341, p = .039). These results suggest adults with ADHD over respond to stimuli as a result of decreased sensitivity.

▼ Introduction: The Canadian Medical Association (CMA)
released guidelines for Fetal Alcohol Spectrum Diagnosis (FASD) in
2005 that attempted to equalize diagnostic practices across Canada.
A multi-disciplinary neurodevelopmental assessment is expected and
the occupational therapist must assess soft neurological signs,
which includes
sensory processing and motor development. In 2007,
Northwest Partnership for FASD Research gathered a panel of OTs to
consult on assessment tools who chose the Short
Sensory Profile
(SSP) as the main
sensory processing assessment tool. Methods: Six
qualitative interviews were completed for data collection. The
inclusion criterion for the participants were involvement with a
FASD diagnostic team and familiarity with the SSP. Qualitative data
from the interviews was coded for likeness and analyzed for themes.
Results: Three main themes developed from this research including:
“Uncertainties about the FASD Diagnostic Process”, “Questioning the
Validity of the Assessment Tool SSP” and “Strengths of the SSP”.
The overaching theme that emerged was that the participants were
attempting to find balance in many different ways throughout their
assessments. While participants predominantly focused on concerns,
they also indicated that the SSP is our best option at this time.
Conclusions: Participants were not completely satisfied with using
the SSP for FASD diagnostic assessments but will continue to use
it. It was suggested that the panel of occupational therapists
should reconvene and consider further options for assessment of
sensory processing for FASD diagnostic assessments. There were also
considerations for occupational therapy university education and
continuing education.

▼ Although
sensory and perceptual symptoms have been associated with ASC from the time that autism was first defined as a diagnosis (Kanner, 1943), and despite many personal accounts from individuals with ASC themselves (Grandin, 2009; Lawson, 1998; O‟Neill, 1999; Williams, 1992), there is a long lasting debate whether
sensory symptoms are a component of core ASC deficits or a co-morbid phenomenon. The current research aimed to explore the pattern of
sensory and perceptual experiences in ASC using the
Sensory Profile Checklist Revisted (SPCR; Bogdashina, 2003). The measure has been useful for guiding clinical intervention, but the structure, reliability and validity is yet to be analysed. The SPCR was completed by support workers based on their observations of 38 individuals with clinical diagnosis of ASC. 40 individuals from the general population also completed the measure based on their observations of someone they knew for more than 6 months. Reporting participants also completed the Autism Quotient (AQ; Baron-Cohen, 2001) and the Adult/ Adolescent
Sensory Profile (ASP; Brown & Dunn, 2002). A principle components factor analysis using promax rotation was conducted for the SPCR, with 4 factors explaining 30.82% of the variance. Internal consistency was high with alphas ranging from .90 to .95. Principle axis factoring was used to analyse the factor structure of ASC traits underlying the AQ. The 3 factor solution, which explained 48.31 % of the variance, was chosen. Internal consistency was moderate to high, with alphas ranging from .56 to .92. Individuals with an ASC were found to score significantly higher on the SPCR than healthy controls (b=78.496, t(77)=4.577, p=.05). AQ scores were found to have a significant effect on SPCR scores with a single score increase in AQ scores predictive of 3.49 point increase in SPCR scores (b=3.49, t(76)=4.795, p<.05). ASP scores were found to have a significant effect on SPCR scores, with a single score increase in ASP scores predictive of 2.78 point increase in SPCR scores (b=2.78, t(36)=8.885, p<0.05). The results suggest that
sensory and perceptual
processing styles of individuals with ASC are significantly different to those of healthy controls. The extracted constructs differ from those originally suggested by Bogdashina (2003), however, it could be argued that wih tighter controls and a larger sample size, the extracted factors would be separated further. The high correlation between items of the SPCR and the AQ suggest that the SPCR is useful tool for evaluating the
sensory and perceptual experiences of individuals with ASC. Whilst it cannot be claimed to aid diagnosis, the structure of the measure is such that it would be a useful tool for parents, carers and clinical professionals to use as a guide for intervention targeted at relieving the need to engage in
sensory seeking or
sensory avoiding behaviours.

▼ Purpose: The purpose of this study was to assess the need and desire of parents of children with Autism Spectrum Disorder (ASD) to receive
sensory processing disorder (SPD) education. We hoped to identify misconceptions of parents about
sensory processing and examined the utility of providing information on SPDs to these parents within the genetic counseling session. Methods: Invitations to participate were sent to support groups in the Southeast United States. A survey tool was used to obtain demographic information. A short presentation was given to clarify the definition of
sensory processing, give examples of signs and symptoms of SPDs, and provide other information regarding
sensory processing. This was followed by a guided discussion with the parents present at the focus group. Participants were asked questions regarding misconceptions, comfort discussing their child’s condition, and feelings of parental competency. Results: A total of three support groups agreed to participate. Focus groups ranged in size from three participants to four participants and lasted fifty minutes to an hour and fifteen minutes. While many parents had at least vague familiarity with SPDs, having received information from a variety of sources, some expressed misconceptions that needed to be clarified. The information provided allowed for a discussion of the child’s behavior in positive terms. A majority of parents expressed a desire for more information regarding
sensory processing disorders. Conclusions: Based on the information gathered, it is hypothesized that including a discussion about
sensory processing may provide an opportunity for parents to discuss their child in a positive manner. In addition, it may allow for identifying misconceptions and allow for better understanding of their child’s behaviors. The findings of this study may assist genetic counselors in addressing parent need for information, therapy, and support as they care for their child with autism.

▼ Behavioral and psychological symptoms of dementia create challenges for those living with neurodegenerative cognitive impairment and their care partners. Pharmacological approaches for treatment of challenging behaviors seen in dementia have limited success and serious side effects. Because of this, nonpharmacological approaches are being investigated with increasing frequency. Of particular interest are nonpharmacological approaches involving environmental stimulation to change behaviors. Success of such approaches relies on sensory processing systems, personal preferences, and environmental congruence. There is limited evidence describing behaviors of persons with cognitive impairment in relation to these components. Currently, there is no guiding model for implementation of environmental and sensory-based strategies with this population. The overall goal of this project is to elaborate on an emerging model describing the relationship among environment, behavior, sensation, and cognitive impairment for community-dwelling adults with mild cognitive impairment or dementia.
Three studies allow for deeper understanding of this relationship. Study one compared behaviors seen in autism spectrum disorder (ASD) with exhibited behaviors of individuals with mild cognitive impairment or dementia. Of neurological conditions similar to dementia, ASD has been chosen as an exemplar for comparison of behavioral expression because evidence supports sensory-based theory and interventions to improve behaviors for those with ASD. Results indicate that ASD behaviors are reported in those assessed, with highest rates of behaviors in those with young age of onset and advanced cognitive impairment severity.
Study two described presentation of behavior, sensory processing, and environment for community-dwelling adults with cognitive impairment in the context of the caregiver situation. Findings reflect dyadic experiences for the person with cognitive impairment and the primary care partner. Emergent themes included consideration of the passage of time, environmental contexts, behavioral adjustments while aging, and overall influences of living with cognitive impairment. Sensory processing assessment using the Adult Sensory Profile identified that all participants had some atypical sensory processing patterns, highlighting a need for attention to environmental congruence to promote adaptive behaviors.
Using data collected in study one and study two, a model was created describing interactions among the person with cognitive impairment, sensation, and the environment as these interactions evolve over time. Areas for future research are conceptualized for implementation of the model. Future research is needed for assessment of the model to test for validity and reliability. Creation of an instrument is needed to place individuals within the model given their behavior and cognitive impairment progression. And, future research is needed to create and test interventions in order to aid in environmental congruence. Long-term goals are to improve…

▼ Deaf individuals may possess enhanced visual
processing abilities, particularly in the periphery. Deaf individuals may also be more accurate at discriminating between faces, compared to their hearing counterparts. We examined deaf and hearing subjects’ ability to discriminate between faces, in either the central or peripheral visual fields, using behavioral measures and EEG. In a delayed matching task, subjects were presented with a 'target' face and after a delay were required to identify which of two 'test' faces matched the target. In separate conditions, images were presented centrally and in the periphery. Thresholds were measured using a forced-choice, staircase procedure and were estimated using Weibull functions to determine the level of similarity between test images associated with 80% correct performance. Overall deaf subjects were more accurate than hearing subjects and this difference was most evident in the periphery. Neurophysiological responses to these images were then assessed using EEG and an oddball paradigm. In this paradigm facial images are presented at a base frequency (6 Hz) and within the sequence a different ‘oddball’ face is presented at a lower frequency (1.2 Hz). The presence of significant responses at the oddball frequency indicates the difference between the faces has been detected. In separate trials we presented subjects with base and oddball images that were more or less similar to each other. Across trials these images were presented either centrally or in the periphery. Both
subject groups showed similar reductions in amplitude at the oddball frequency for images that were more similar to each other. However, compared to hearing subjects, deaf subjects showed a larger decrease in amplitude when images were presented in the periphery compared to centrally. Results of the behavioral experiment support earlier findings that deaf individuals may possess enhanced face discrimination abilities and further extend them by showing that these effects may be more prominent in the periphery. Furthermore, our results from the EEG experiment suggest that the enhanced
processing ability in deaf for peripherally presented faces is not necessarily related to higher amounts of neurophysiological activity at the level of face coding. This discrepancy between the two experiments in the present study may be due to differences in the task demands, with the behavioral experiment reflecting more local feature discrimination, while the EEG experiment may reflect more holistic face coding.

▼ It is estimated that up to 95% of children with autism spectrum disorder experience sensory processing problems. Minimal research is available on the relationship between specific sensory processing patterns, activity preference and behavior patterns in children. It is hypothesized that if children participate in play activities that support their sensory needs, they will experience less behavioral problems, more self-regulating behavior and a higher quality of life. This mixed-methods case study examines how a child with autism spectrum disorder participates in activities and looks at if those activities support sensory needs, thus reinforcing self-regulatory behaviors.

▼ A child’s ability to process, organize, and respond to incoming
sensory information and to self-regulate often impacts his or her school performance. The Alert Program, was established with the goal of teaching students the skills needed for self-regulation and therefore, has the potential to yield school function outcomes. This study examined the impact of a classroom approach to the Alert Program on school function for identified at risk students. Retrospective in nature, subjects for this study included 104 kindergarten students at an independent private school in eastern North Carolina between the years 2010-2014. Program implementation consisted of 40-60 minute weekly sessions over 5 months; sessions were led by three to four East Carolina University Occupational Therapy students. Data was collected using the
Sensory Processing Measure: Main Classroom (SPM-C) and the School Function Assessment–Part III Activity Performance: Cognitive/Behavioral tasks (SFA). A master panel comprised of early elementary teaching faculty provided input as to what areas of school function are addressed, expected, and most developmentally appropriate at the kindergarten level; feedback revealed that the areas most relevant include: following social conventions, personal care awareness, behavior regulation, task/behavior completion, and positive interaction. Data analysis of student performance on the SFA in each of these pre-identified categories showed significant improvement (p < .05) for identified at risk students after participation in the Alert Program. Results suggest the Alert Program, a
sensory-based approach to teaching self-regulation, produces end outcomes in areas of school function, particularly for at risk students. However, while the classroom approach was successful for the majority of students, some students may likely benefit more from an individualized approach.

▼ Attention is a crucial element of our goal-directed, purposeful response to
sensory information in our social and physical environments. Individuals with autism spectrum disorders (ASD) have significant deficits in
sensory processing and attention. However, there is limited research examining the relationship between attention and
sensory processing in individuals with autism spectrum disorders (ASD). The purpose of this dissertation was to examine the relationship between attention and
sensory processing in individuals with autism spectrum disorders (ASD) and neurotypical individuals. Specifically, the objective was to examine if consciously directing attention to incoming information would result in more typical neural
processing in individuals with ASD. To answer this question, study 1 was designed to understand how attention and distraction impacted
sensory processing in neurotypical individuals. Studies 2 and 3 examined neural measures of
sensory processing in individuals with ASD as compared to age-matched neurotypical controls during passive and active attentional states. In Study 1, electroencephalography (EEG) data were recorded while 60 adults (18-35 years) heard random presentations of 4 auditory stimuli at 2 frequencies (1 and 3 kHz) each at 2 intensities (50 and 70 dB). Participants were randomly divided into 2 viewing conditions; one group watched a silent movie and the other viewed a fixation point during the recording. All participants completed 2 attention conditions, the passive condition involved only listening to the stimuli, followed by the active condition, wherein participants were instructed to press a button to the 1 kHz 50 dB tone. Amplitude and latency measures were obtained for the N1, P2, N2, and P3 components for each of the auditory stimuli. The ANOVAs revealed a significant main effect of attention condition for the N1, P2, N2, and P3 amplitudes. There were also significant attention-by-viewing condition interaction effects at the P3 component. Results indicated that actively directing attention to the tones impacts auditory
processing at all components. Additionally, manipulation of attention by changing the viewing environment significantly interacted with
sensory processing, such that movie viewing resulted in larger P3 amplitudes compared with fixation viewing. Thus, viewing environment or distraction impacts
sensory processing. In study 2, we examined the effect of attention on auditory filtering using the
sensory gating paradigm in individuals with ASD. EEG data were recorded during 2 attention conditions from 24 adults with ASD and 24 neurotypical individuals during the
sensory gating paradigm. During the passive condition, participants were presented with single and paired clicks. For the active condition, participants made a motor response following the single click but not the paired click. Attending to the clicks resulted in larger P50 and N1 amplitudes, and reduced gating for all participants. Although, the ASD group had P50 and N1 gating during both attention…

▼ Auditory
processing is one of the most commonly reported
sensory processing impairments in autism spectrum disorders. This study sought to determine whether children with high-functioning autism spectrum disorders (HFA) differ from typically developing children on neurophysiological measures of auditory information
processing. We hypothesized that children with HFA would have significant different brain activity when listening to auditory stimuli compared to typically developing children. A cross-sectional quasi-experimental quantitative study design with convenience sampling procedures was employed to compare two groups. Nineteen children with HFA and 19 age- and gender-matched typically developing children, ages 5 to 12 years, participated in this study. Electroencephalography (EEG) recordings were made while participants watched a silent movie and heard random presentations of four auditory stimuli at two different frequencies (1 and 3 kHz) and at two different intensities (50 and 70 dB). The stimuli were presented in 4 blocks of 100 trials each, with 25 trials of each of the stimuli in random order with a 2-second inter-stimulus interval. Amplitude and latency measures were obtained for the P1, N1, P2, N2, and P3 components from the averaged event-related potentials (ERPs) for each of the four auditory stimuli. An analysis of variance for the ERP components, revealed that children with HFA had significantly smaller N2 amplitudes for the low frequency low intensity tone, and significantly smaller P3 amplitudes to the high intensity at both frequencies stimuli compared to typically developing children. This finding suggests that children with HFA have increased difficulty in automatic stimuli discrimination and reduced cognitive
processing to these auditory stimuli. Children with HFA also had significantly longer P2 latencies for the high intensity high frequency tone compared to typically developing peers, suggesting delayed auditory
processing. In conclusion, this study shows that children with HFA display different brain
processing mechanisms to auditory
sensory stimuli compared to typically developing children. These differences suggest that the auditory
processing deficits observed in children with HFA may arise from atypical neurophysiological functioning related to stimuli discrimination and
processing. These results can help practitioners understand the neurophysiological basis of behavioral manifestations of ASD, especially those atypical behaviors that occur in response to
sensory experiences in everyday activities. Understanding the specific aspects of
sensory processing that are a challenge for children with HFA may provide guidance to the types of treatment strategies that will be most effective.

▼ Children have occupations they need to perform in order to learn, grow, and develop. Challenges in
processing and integrating
sensory information can impair their capacities . for occupational participation and engagement.
Sensory integration interventions have been promoted as able to help children improve their abilities to use
sensory information for function as well as provide strategies for self-regulation. Much of the research on the efficacy of
sensory integration interventions is experimental and descriptive, and largely inconsistent. Qualitative methodologies have not been widely used to examine the approach or to investigate the first-person experiences of the children who participate in
sensory integration interventions. This phenomenological qualitative research study investigated ~he life experiences of a child with challenges in
sensory processing and integration who had received
sensory-based occupational therapy intervention. The themes identified were freaking out and I engage. The perspectives acquired can help influence the clinical reasoning of occupational therapists and expand the research base of
sensory integration interventions.

▼ In addition to the core social and communication symptoms, individuals with autism spectrum disorders (ASD) have high rates of sensory over-responsivity (SOR). Despite the fact that over half of children and adolescents with ASD have SOR, very little is known about the neurobiological bases of this condition. SOR often co-occurs with anxiety disorders, which suggests a possible common biological basis for both SOR and anxiety in a subgroup of youth with ASD. The following studies used functional magnetic resonance imaging (fMRI) to examine brain response to mildly aversive sensory stimulation in youth with and without ASD, with a focus on brain areas responsible for primary processing of sensory information as well as those linked to anxiety and emotion regulation. Results suggest that youth with ASD and SOR have deficits in both primary sensory processing as well as in regulating emotional response to sensory information. These deficits are associated with reduced amygdala-prefrontal functional connectivity during exposure to sensory stimuli as well as reduced habituation to the stimuli. Findings can inform intervention, including better classification and targeted treatment for subgroups of youth with ASD, and treatment focused on building coping skills for sensory stimulating environments.

▼ Recent theories of motor control emphasize the role of sensory feedback in driving motor output and how feedback could be flexibly modulated to adapt to the behavioural requirements of a task. Here, we tested the merits of this theory by studying how sensory feedback is modulated by behavioural context and studied the possible neural circuitry underlying such task dependent processing. Mechanical perturbations were applied to the arms of our subjects (in humans or non-human primates) in different behavioural tasks to quantify task-dependent muscle responses. We also quantified cortical responses in non-human primates to explore the neural basis of this flexible feedback processing. Our first experiment (Chapter 2, human study) shows that introducing redundancy in a bimanual postural control task could rapidly change the magnitude of muscle responses to the perturbations in as little as 50ms. In our second experiment (Chapter 3, NHP study), we show that primary motor cortex (M1) responses to mechanical perturbations were rapidly modulated (in as little as 40ms), when the monkey was engaged or not in a postural control task (task-dependent response). Strikingly, the initial perturbation responses remained identical across tasks (task-independent response). We speculated that different sources of feedback, with different time delays and sensitivity to behavioural tasks, might be driving M1 activity; one driving the early task-independent response and the other driving the late task-dependent response. We therefore, studied perturbation responses in a range of sensory and motor cortices across 3 different behavioural contexts (Chapter 4, NHP study). We found sensory feedback to be rapidly transmitted to all these cortical regions within 25ms of limb disturbance. Furthermore, sensory feedback was differentially modulated across these areas, depending on the behavioural task. For instance, posterior parietal area 5 was the first area to show response modulation with task engagement (same as experiment 2). Primary motor cortex, on the other hand, was the first area to show modulation in perturbation response with different spatial targets (i.e., target selection). These results suggest that a highly distributed neural substrate is involved in processing sensory feedback and each area plays a unique role in context-dependent modulation of feedback responses.

▼ This research is concerned with functional magnetic resonance imaging (fMRI) of the brain during auditory information
processing. The main focus is the exploration of the brain areas involved in
sensory gating, i.e., the ability of the central nervous system (CNS) to inhibit or modulate its sensitivity to incoming irrelevant
sensory auditory input, as measured using a paired auditory stimulus paradigm.
It is well-known that the brain’s responses are variable from trial-to-trial. This calls into question the current practice of using a single, representative response function (canonical HRF) to model fMRI data. Therefore, a correlation-based method was developed to deal with the variability of the HRF in response to repeated presentation of identical auditory stimuli. The goal of the analysis technique is to identify ‘active’ trials among all single trials. We verified that this correlation-based method can find significant differences between brain areas and brain states in actual fMRI data.
Second, we determined if the cluster-based method can improve conventional fMRI analysis by exploring the brain regions involved in
processing single stimuli using both methods. Data was collected from 14 healthy subjects listening to auditory tones. Our results indicated that by focusing on ‘active’ trials only, as determined by the clustering method, we obtained better statistical maps and that the sensitivity of the fMRI data analysis was increased through the identification of activated areas.
The results indicated that the superior temporal gyrus (STG), inferior frontal gyrus (IFG), dorsolateral prefrontal cortex (DLPFC), and thalamus (THA) were involved in auditory information
processing and
sensory gating in general. While the conventional analysis could not find any regions involved in gating, the correlation-based method confirmed the involvement of bilateral STG, right THA and left DLPFC in
sensory gating. Specifically, the right THA relays the
sensory signal to the STG, with the bilateral STG involved in the first stage of auditory
processing and the left DLPFC involved in the inhibitory circuit of
sensory gating
processing.
Our findings suggest that the correlation-based single trial analysis method provides quantitative assessment of the neuronal origins of the
sensory gating. It also improves the current fMRI analysis technique.

▼ It is indisputable that good oral health is important
to both psychological and physiological health. However, despite
the importance of oral care, disparities exist for children with
special health care needs (CSHCNs) in the access to and practice of
oral care in the United States, with oral care being the most
frequently cited unmet health care need; one group of CSHCNs that
may be at particular risk for poor oral health is children with
autism spectrum disorders (ASD). The three studies in this
dissertation aimed to investigate challenges encountered in
children with ASD in regard to oral care and to examine if
behavioral and physiological measures of
sensory processing
difficulties were related to difficulty with oral care. ❧ In the
first study we explored the differences between children with ASD
and their typically developing (TD) peers in relation to aspects of
oral care. Participants were 396 parents of children with ASD or
typically developing children ages 2-18 years of age. Parents
completed a 37-item questionnaire designed by authors to elicit
information about oral care in the home and dental office.
Significantly more parents of children with ASD in comparison to
parents of typically developing children reported difficulty across
almost all oral care variables explored, including oral care in the
home, oral care at the dentist, and access to oral care. This study
indicates that children with ASD experience greater difficulties
and barriers to care in both the home and dental office settings
than their typically developing peers. ❧ In order to investigate
the relationship between
sensory sensitivities and oral care
difficulties, we conducted study two. Participants included 396
parents of 2- to 18-year-old children with ASDs or TD who completed
a questionnaire about oral care in the home and dental office. We
found that (1) children with ASD vs. TD children were reported to
have a significantly greater prevalence of
sensory
over-responsivity across all
sensory domains, and (2) children with
ASD characterized as “
sensory over-responders” exhibited a
significantly greater prevalence of oral care difficulty in the
home and dental office vs. children with ASD who responded more
typically to
sensory stimuli (“
sensory not over-responders”). This
study provides further evidence for the impact of
sensory
processing problems on oral care, both in the home and dental
office. Methods to best serve children with autism spectrum
disorders may include strategies that alter the
sensory
characteristics of the dental environment as well as interventions
to reduce children’s
sensory sensitivities. ❧ As the results of
study two suggested that
sensory processing difficulties are
associated with difficulties with oral care on parent-report
behavioral measures, the third study examined if there is a
physiological difference between arousal and
sensory responsivity
in children with ASD and TD children during oral care, utilizing
electrodermal activity collected during a routine dental cleaning.
Additionally, it investigated…

▼ Prediction of children at risk for sensory over-responsivity (SOR) is difficult. Children are not typically identified until school age, resulting in frustration for caregivers and impact upon child development. Prediction of SOR could aid early intervention and possibly lead to prevention for some children. This research aimed to determine the pre- and perinatal predictors of SOR and used infant sleep and feeding difficulties, thought to reflect poor regulation, as a proxy for infants who would later develop SOR. Thirty-eight pre- and perinatal factors were examined and eighteen formed a unidimensional construct. Children with SOR and infants with and without sleep/feeding difficulties were compared on the 18-variable construct using Rasch analysis, differential analysis and classification functions. Four variables (anaesthesia, oxytocics, parity and history of maternal mental health treatment) were associated with infants with sleep/feeding difficulties compared with those without difficulties; when the four variables were considered together, they were best at predicting infants without sleep/feeding difficulties. In addition, four variables (parity, resuscitation intervention, SES and stage 1 labour) were associated with children with SOR in comparison with infants with and without sleep/feeding difficulties. Pre- and perinatal factors are important to the prediction of both SOR and infant sleep/feeding difficulties.

▼ O presente trabalho visou o desenvolvimento, aceitabilidade, análise nutricional e vida de prateleira de geleia convencional e light de uva cultivar BRS Violeta, utilizando a sucralose como edulcorante. Foram avaliados quatro tratamentos, sendo T1 – Convencional (60 % polpa: 40 % açúcar cristal), T2 - Light 1 (60 % polpa: 30 % açúcar cristal + 10 % sucralose), T3 - Light 2 (60 % polpa: 28 % açúcar cristal + 12 % sucralose), T4 - Light 3 (60 % polpa: 24 % açúcar cristal + 16 % sucralose). Para ocorrer à formação do gel característico da geleia, foram adicionados às formulações, pectina cítrica e ácido cítrico. As geleias foram avaliadas quanto teores de sólidos solúveis, pH, acidez total titulável, açúcar redutor e açúcar total, compostos fenólicos totais, atividade antioxidante total, pigmentos e flavonoides, cor instrumental, análise microbiológica, análise sensorial e avaliação energética, durante um período de 120 dias de armazenamento. Os teores de sólidos solúveis diminuíram durante o tempo avaliado. Houve pequena elevação nos teores de acidez total titulável, principalmente nas formulações light. Os compostos fenólicos e os antioxidantes decaíram durante o armazenamento. As versões de geleia Convencional e Light 2 demonstraram maior estabilidade no tempo armazenado, considerando assim viáveis para fabricação. Não ocorreu contaminação microbiológica nas geleias até os 120 dias de armazenamento, apresentando-se satisfatórias ao consumo. Todas as versões de geleias foram bem aceitas pelo consumidor evidenciando potencial valor comercial.
This work aimed at the development, acceptability, nutritional analysis and shelf life of conventional and light grape jam BRS Violeta using sucralose as a sweetener. We evaluated four treatments: T1 - Conventional (60% pulp: 40% crystal sugar), T2 - Light 1 (60% pulp: 30% granulated sugar + 10% sucralose), T3 - Light 2 (60% pulp: 28% crystal sugar + 12% sucralose), T4 - Light 3 (60% pulp 24% granulated sugar + 16% sucralose). For the formation of the characteristic occurs gel jam were added to the formulations, citric pectin and citric acid. The jams were evaluated for soluble solids, pH, titratable acidity, reducing sugar and the total sugar, total phenolics, total antioxidant activity, pigments and flavonoids, instrumental color, microbiological analysis, sensory analysis and energy assessment for a period of 120 days' storage. The soluble solids decreased during the evaluated time. There was a slight increase in levels of total acidity, especially in light formulations. The phenolics and antioxidants declined during storage. The Conventional and Light 2 jam versions showed greater stability in storage time, thus considering feasible to manufacture. There was no microbiological contamination jam until 120 days of storage, presenting satisfactory consumption. All versions of jams were well accepted by the consumer showing potential commercial value.

▼ Development of complex sound representations in the primary auditory cortexbyMichele Nerissa InsanallyDoctor of Philosophy in NeuroscienceUniversity of California, BerkeleyProfessor Shaowen Bao, PhD., ChairThe brain has a tremendous ability to change as a result of experience; this property is known as plasticity. Our mastery of soccer, rhetoric, agriculture and instrumentation are all learned skills that require experience. While the brain is plastic throughout life, during early development, the brain demonstrates a heightened sensitivity to experience. This unique epoch during development in which the brain is particularly susceptible to change is called a critical period. During the critical period, sensory experience results in significant modifications in structure and function. The set of studies described in this dissertation aim to investigate how complex sound representation develops during the critical period in the rat primary auditory cortex. Previous examinations of the critical period in the auditory cortex have typically used simple tonal stimuli. Repeated exposure of rat pups to a tone, for instance, has been shown to selectively enlarge cortical representation of the tone and alter perceptual behaviors. However, probing cortical plasticity with a single-frequency tone might not reveal the full complexity and dynamics of critical period plasticity. After all, natural, biologically important sounds are generally complex with respect to their spectrotemporal properties. Natural sounds often have frequencies that vary in time and amplitude modulation. Psychophysical studies indicate that early experience of complex sounds has a profound impact on auditory perception and perceptual behaviors. Experience with speech, for instance, shapes language-specific phonemic perception, enhancing perceptual contrasts of native speech sounds and reducing perceptual contrasts of some foreign speech sounds. At the electrophysiological level, auditory cortical neurons preferentially respond to certain complex sounds, such as species-specific animal vocalizations. It is unclear how such selectivity for a complex sound emerges, and whether it is innate or shaped by early experience.In order to address this question, we exposed rat pups to a frequency-modulated (FM) sweep in different time windows during early development, and examined the effects of such sensory experience on sound representations in the primary auditory cortex (AI). We found that early exposure to an FM sound resulted in altered characteristic frequency representations and broadened spectral tuning in AI neurons. In contrast, later exposure to the same sound only led to greater selectivity for the sweep rate and direction of the experienced FM sound. These results indicate that cortical representations of different acoustic features are shaped by complex sounds in a series of distinct critical periods.Next, we confirmed this model of brain development in a set of experiments that examine how exposure to noise affects these various critical periods. We…

▼ Using parent-report measures, prior studies have shown that
sensory processing is related to social, emotional, and regulatory development. The current study examined 9-month-old infants’
sensory processing during a parent-child interaction, in relation to prenatal environment and child temperament. Latent Class Analysis yielded four
sensory processing classes that were consistent with current models of
sensory processing: Typical,
Sensory Seeking,
Sensory Sensitive, and
Sensory Avoiding. Analyses examining class differences on parent-report and observational measures of temperament indicated that measures of
sensory processing do not reflect overall reactivity to frustrating situations. Analyses examining class differences on prenatal environment indicated that complications during pregnancy (e.g., infections, weight gain and loss, prenatal care) were predictive of high reactivity to and avoidance of
sensory stimulation at 9 months. Implications of findings are discussed, along with directions for future research.

▼ ENGLISH ABSTRACT: Application of steam treatment to green Cyclopia maculata and C. longifolia to modulate their aroma
and flavour profile, without detrimental effects on colour and individual phenolic content, was
investigated. Steam treatment (96 °C, atmospheric pressure) of different time periods was applied
to the shredded, fresh plant material before drying (STBD; 0, 30, 60, 90 and 120 s) or the herbal tea
product after drying (STAD; 0, 1, 2, 3, and 4 min). Steam treatment of 60 s or longer resulted in a
significant (p < 0.05) decrease in vegetative (‘green grass’ and ‘hay/dried grass’) and cereal
(‘oats/porridge/grains’) aroma and flavour intensities, with an increase in some fruity (‘tropical fruit’
and ‘guava’) and ‘fruity-sweet' aroma intensities. These changes manifested to a greater degree for
plant material subjected to STBD, while they were less prominent for C. longifolia compared to
C. maculata. Additionally, 19 aroma compounds were instrumentally identified in the volatile fraction
of C. maculata infusions prepared from STBD plant material. Of these, seven correlated well with
green honeybush vegetative and cereal aroma attributes associated with unsteamed samples.
Steaming thus resulted in the rapid loss of some of these highly volatile ‘green’-associated aroma
compounds. Steam treatment of more than 60 s, regardless of STBD or STAD, was not detrimental
to green colour, and individual phenolic content was not greatly affected. The 30 s STBD treatment
of C. maculata, however, led to the rapid loss of green colour and oxidation of phenolic compounds,
without considerable aroma improvement. This highlights the need for process control during green
honeybush production. Storage stability of steamed (60 s, STBD) and unsteamed green C. maculata was
investigated under low (0 °C; moisture impermeable packaging) and normal (25 °C at 60% relative
humidity (RH); semi-moisture-permeable sachets) temperature storage conditions (LTS and NTS,
respectively) over 6 months and high temperature storage (HTS) conditions (40 °C at 75% RH; semimoisture-
permeable sachets) for 1 month. HTS conditions, after 1 month, seemed to emulate
changes occurring over 6 months at NTS conditions, with little change detected at LTS conditions.
Despite noticeable green colour loss over the respective storage periods at NTS and HTS conditions,
individual phenolic compounds were not severely affected. NTS and HTS led to the progressive
development of sought-after fermented honeybush
sensory attributes, especially in unsteamed
samples. These include prominent fruity (‘stewed fruit’, ‘apricot jam’ and ‘marmalade’) aromas and
flavours, ‘general sweet’ and ‘fruity-sweet’ aromas and a sweeter taste. The collated descriptive
sensory data were used to generate a preliminary
sensory wheel for
green honeybush aroma, and another for flavour, taste and mouthfeel. The
sensory profile of green
honeybush was finally described as a dominant vegetative aroma and flavour, prominent sweetassociated
and slightly fruity aroma,…

▼ Masters Coursework - Masters of Clinical Psychology (MClinPsych)
Previous literature has demonstrated high heritability in Attention Deficit Hyperactivity Disorder (ADHD) and identified some early risk factors in later development of ADHD, including language ability, motor skills and temperament. Emerging evidence has further suggested the possible link between ADHD and poor cognitive functioning and sensory processing. However, little research has done on the relationship between familial ADHD liability and the expression of those early risk factors during infancy. This study explored how familial ADHD liability associated with infants’ behaviours at their first year of life. Infants were categorized into ADHD and control group based on their parental history of ADHD. Standardized assessment and parental reports were used to examine infants’ cognitive functioning, sensory processing, communication, motor ability and temperament. Results indicated that there were no significant differences in behavioural outcomes between infants with and without familial ADHD liability at both 6 and 12 months of age. These results suggested that familial history of ADHD was not a good predictor to detect early differences of cognitive functioning, sensory processing, communication, motor ability and temperament in infancy. Future research is necessary to fully understand the manifestation and pathogenesis of ADHD.

▼ The potato (Solanum tuberosum L.) is the world's third largest food crop with per capita consumption of ~126 lbs. annually in the US. The 2010 US Potato Board Report revealed that over the past ten years, while consumption of traditional potatoes (mashed, baked, fried, steamed, boiled and french fries) declined, specialty/colored potato consumption increased by 17%, possibly due to their putative health benefits. Specialty/colored potatoes, which are rich in anti-proliferative and pro-apoptotic anthocyanins and/or carotenoids, can be an attractive "delivery system" for these bioactive compounds in humans. However, colored potatoes can undergo 3-6 months of storage before
processing/consumption and the effect of storage and
processing on their anti-cancer properties remains unknown. We hypothesized that potatoes retain polyphenolic content (TP), antioxidant activity (AA) and chemopreventive properties against early stage (HCT-116) and advanced stage (HT-29) human colon cancer cells even after 3 months of storage and
processing (baking and chipping). To test this hypothesis, we utilized white-, yellow- and purple-fleshed potato clones and tested their phenolic (Folin-Ciocalteu) and anthocyanin (pH-differential) content, antioxidant activity (ABTS and DPPH), metabolite profile (UPLC-MS), anti-cancer properties (cell proliferation via cell counting and BrdU assays, and apoptosis via Caspase-Glo 3/7 assay), and
sensory attributes (9-point hedonic scale). Purple-fleshed potatoes had higher phenolic content and antioxidant activity as compared to their white- and yellow-fleshed counterparts. The antioxidant activity of all clones increased with storage; however, an increase in total phenolic content was observed only in purple-fleshed clones. Baking caused minimal losses while chipping reduced the phenolic and anthocyanin content, and antioxidant activity of the potatoes. With storage, total phenolic and anthocyanin content, and antioxidant activity increased in baked samples while in the chipped samples, they remained constant. Principal component analysis of approximately 1600 peaks obtained by UPLC-MS analysis revealed that storage caused a shift in the metabolite profiles of potato clones. In general, ethanol extracts of uncooked, baked and chipped samples suppressed proliferation and elevated apoptosis (p < 0.05) in human colon cancer cell lines (HCT-116, HT-29). However, chipped samples did not have any effect on HT-29 cell lines. Anti-proliferative and pro-apoptotic properties of baked potatoes were similar to that of raw potatoes while chipping caused a significant reduction in the biological activity. Storage generally negatively affected the anti-cancer properties of the potato extracts.
Sensory analysis revealed comparable acceptance of purple-fleshed baked and chipped potatoes when compared with traditional cultivars. Consumers were willing to pay a premium for colored-flesh potatoes if they were educated on their potential health benefits. Phenolic content and antioxidant activity of purple-fleshed potatoes,…

▼ INTRODUCTION Schizophrenia-spectrum disorders (SZ) are characterized by disturbances of early information
processing across various
sensory modalities that originate from disrupted spatial and temporal linkage in critical
neural networks that include the limbic system and
sensory cortices. These disturbances are known to underlie
impairments in social cognition, i.e. the ability to understand the thoughts and behaviors of others, which is a
critical skill for effectively navigating the social world. Patients with SZ have widespread social cognitive deficits
that interfere with social relationships and impair occupational functioning. Current pharmacological treatments
are ineffective in remediating social cognitive deficits and in regulating their neurophysiological underpinnings.
The oxytocin (OT) system, which is critically involved in social behavior and cognition in mammals and is
dysregulated in SZ, is a promising target. Intranasal administration of exogenous OT is well tolerated and
improves social cognition in patients with SZ. Additionally, neuroimaging studies in healthy individuals suggest
that OT improves information
processing and social cognition by modulating regional activity within those neural
networks that are impaired in SZ. While work on healthy individuals is promising, no studies investigated the
effects induced by OT on spatiotemporal neural oscillatory patterns in patients with SZ.
MATERIAL & METHODS. In this study, I used Magnetoencepholagraphy Imaging (MEG-I) to examine the
effects of OT. I administered a single intranasal dose of OT (40 IU) or placebo (PL) in a randomized, doubleblind,
counterbalanced order with a cross-over, within-
subject design to 25 males with SZ and 25 matched
healthy controls (HC). Participants’ brain activity was recorded using MEG-I while they completed an auditory
deviance task and a facial emotion
processing task that robustly activate neural networks underlying information
processing and social cognition. Change in auditory mismatch negativity induced by OT/PL in SZ and HC was
assessed repeated measures ANOVA. Induced oscillatory activity in regions displaying early activation patterns
was examined using adaptive spatial filtering techniques. Broadband activity estimated at each time point in a
trial was averaged across trials, root-mean-square transformed, and z-normalized. Average amplitude from early
time windows post-stimulus onset was calculated to assess early responses in the bilateral occipital face area
(OFA) and the right amygdala. The Neurodynamic Utility Toolbox for MEG-I was used to conduct an exploratory
time-frequency analysis of the neural sources during the
processing of facial emotions. Task-induced neural
oscillatory power changes were localized and examined after OT and PL administration.
RESULTS. Compared to HC, SZ showed reduced amplitude of the mismatch negativity under PL. This
impairment was normalized after OT administration. Under the effects of PL, the exploratory time-frequency
analysis found differential…

▼ Can listening to information at a low volume improve hearing? To test this hypothesis this experiment had undergraduate students listen to a podcast at a low volume. In addition, this study also explored expectation or priming someone to anticipate a particular outcome. The central questions of this study asked how both listening to a podcast at a low volume and expectation influenced hearing outcomes, reaction times, the comprehension of auditory information and perceived mindfulness. A secondary line of inquiry examined whether one’s perceived mindfulness is correlated with reaction times. To this end, 111 Harvard undergraduate students with no history of hearing impairment were recruited into a 2 x 2 factorial designed study, where podcast volume and expectation were the factors at play. All participants completed a Langer Mindfulness Scale and a hearing test before being placed into one of four conditions: condition 1, participants listened to a podcast at a regular volume and were told they could expect their hearing to improve, condition 2, participants listened to a podcast at a regular volume, condition 3, participants listened to a podcast at a low volume and were told that they could expect their hearing to improve, and condition 4, participants listened to a podcast at a low volume. Participants then completed a second Langer Mindfulness Scale and hearing test, as well as a visual reaction time test, an auditory reaction time test and a quiz designed to test participants’ comprehension of the podcast material.
This study found that found that that participants that listened to podcasts at a low volume would experience improvements in their posttest hearing test scores. Additionally, being within an expectation group was significantly associated with better scores on hearing tests. It should be noted that this study presupposed that listening to podcasts at a lower volume level will allow participants to mindfully notice change. Due to the fact that other mindfulness interventions have produced positive changes in auditory processing (Langer, 2009) this study’s results may give further credence to the notion that engaging in mindfulness can positively impact sensory processing. In light of these results it may be prudent to explore whether listening to information at a low volume can improve the hearing of those who live with mild to moderate hearing impairment.
Conversely, based on the analysis of this thesis the podcast volume and expectation were not significantly correlated with reaction times or perceived mindfulness. Similarly, perceived mindfulness was not significantly correlated with reaction times. Lastly, the comprehension assessment used to evaluate the comprehension of podcast material proved to be too easy. As a result, a ceiling effect was observed and thus whether listening to podcasts at a low volume impacts comprehension remains unknown.
