▼ People are constantly confronted by a barrage of visual information. Visual attention is
the crucial mechanism which selects for further processing, subsets of information
which are most behaviourally relevant, allowing us to function effectively within our
everyday environment. This thesis explored how semantic information (i.e., information
which has meaning) encountered within the environment influences the selective
orienting of visual attention. Past research has shown semantic information does affect
the
orienting of attention, but the processes by which it does so remain unclear. The
extent of semantic influence on the visual attention system was determined by parsing
visual
orienting into the tractable components of covert and overt
orienting, and
capture and hold process stages therein. This thesis consisted of a series of experiments
which were designed, utilising well- established paradigms and semantic manipulations
in concert with eye-tracking techniques, to test whether the capture and hold of either
overt or covert forms of visual attention were influenced by semantic information.
Taking together the main findings across all experiments, the following conclusions were
drawn. 1) Semantic information differentially influences covert and overt attentional
orienting processes. 2) The capture and hold of covert attention is generally
uninfluenced by semantic information. 3) Semantic information briefly encountered in
the environment can facilitate or prime action independent of covert attentional
orienting.4) Overt attention can be both preferentially captured and held by
semantically salient information encountered in visual environments. The visual
attentional system thus appears to have a complex relationship with semantic
information encountered in the visual environment. Semantic information has a
differential influence on selective
orienting processes that depends on the form of
orienting employed and a range of circumstances under which attentional selection
takes place.

The Effect of Multimodal Rhythms on the Allocation of

▼ Attention to rhythmic stimuli can be
conceptualized as involving periods of variable attention such that
the distribution of attention is entrained to the rhythm of the
stimulus. This entrainment process has crossmodal consequences,
such that both auditory and visual attention is entrained by an
auditory rhythm and vice versa, resulting in improved responses to
auditory or visual targets when their onsets match the temporal
structure of a preceding rhythm. The current study examines the
role of multimodal entrainment on the allocation of auditory and
visual attention. Specifically, we were interested in situations in
which concurrently presented auditory, visual rhythms correspond
temporally, and situations in which concurrently presented auditory
and visual rhythms conflict temporally. In Experiment 1,
participants were entrained by three different rhythm
types: audiovisual, auditory-only, and visual-only. They responded
to auditory and visual targets occurring at the end of rhythm that
either matched or mismatched the entrainment rhythm. Response time
was fastest when targets matched the entrainment rhythm, verifying
that entrainment occurred, and did not differ across rhythm type or
target modality (auditory vs. visual), indicating that audiovisual
entrainment was no more effective than auditory-only or visual-only
entrainment. In Experiments 2 and 3, participants were presented
with temporally conflicting auditory and visual rhythms.
Participants responded to auditory and visual targets that matched
the temporal structure of either the auditory or the visual rhythm.
Response times were fastest when target onsets matched the temporal
structure of the visual rhythm compared to the auditory rhythm and
did not differ by target modality. Overall, this work suggests that
entrainment is a general attentional mechanism that is applied
across sensory modalities. Furthermore, it suggests that when
auditory and visual rhythms do not share the same temporal
structure the attentional system favors the timing parameters of
the visual rhythm.

▼ Stimulus-elicited (phasic) skin conductance responses
(SCRs) to indifferent stimuli have often been employed to examine
abnormalities in orienting (allocation of attention) in studies of
schizophrenia. Most previous studies have examined phasic activity
only during habituation paradigms. Interpretation of many studies
is complicated because patients are medicated during testing. In
this study cross-modal orienting response dishabituation paradigm
was presented to 68 normal controls and 47 unmedicated
schizophrenia patients while SCRs were recorded. Gender and
laterality (bilateral recording in right-handed participants) were
varied between- and within-subjects, respectively. Overall
reactivity, and the following four discrete attentional effects
were examined: habituation; reinstatement; “super reinstatement”;
and dishabituation. For all participants, overall reactivity was
lower for schizophrenics than for normal controls, as indexed by
both amplitude- and response frequency-based measures. For SCR
responders only, overall responsivity did not differ between
groups. For SCR responders, habituation, reinstatement, and
dishabituation were evident across groups. Super reinstatement
approached significance.

▼ Social behavior is arguably one of the most complex forms of behavior exhibited by animals. It requires active attention to dynamic multisnsory cues, recall of past experiences, and the generation of situationally appropriate responses. Given the swath of different cognitive systems required, it is unsurprising that social behavior is disrupted in many neurological disorders. Autism spectrum disorders (ASD) are particularly notable, as social impairment is a required diagnostic criteria. Efforts using animal models to both understand the etiology and improve behavioral outcomes for human ASD patients are complicated by the difficulty of replicating the genetic environmental causes. Similarly, measuring deficits in complex behaviors like social interaction is challenging and their neuroanatomical correlates are not yet fully described.
To address these issues, I utilized the highly social and genetically tractable zebrafish (Danio rerio) as a model system. I developed a novel assay that shows social engagement requires a behavioral visual stimulus provided by another socially-engaged fish. I demonstrated that both pharmacological manipulation of dopaminergic systems and ablation of a portion of the ventral telencephalon produce predictable deficits in social behavior. Our results also provide evidence that an as yet uncharacterized population of cholinergic neurons in the ventral forebrain are critical for social interactions in zebrafish. This region corresponds to mammalian forebrain regions implicated in social behavior, suggesting an evolutionarily conserved population of cells may drive social
orienting in zebrafish and mammals. Further, I identified the time points in early development when specific social behaviors are first observed, suggesting a progressive acquisition of increasingly complex social behaviors over a rapid timescale. This highly variable and early stage in development represents an opportunity to further understand how genetic and environmental factors affect the assembly of the neural circuits underlying complex behaviors.

▼ The current paper examines the development of children’s understanding of arrows. Infants (8-10 months), children (3-7 years) and adults were tested in a spatial cueing paradigm in which arrows were used as a litmus test for understanding
the shift from perceptual to conceptual understanding. In this respect, it investigates what property or properties of an arrow cue attention in the first years of life. The present study reveals that individuals who do not yet understand the directional
meaning of an arrow may be cued by its perceptual characteristics, but once an individual understands the directional meaning of an arrow, this conceptual understanding prevails over the perceptual characteristics. A framework is suggested which may help
to explain the developmental shift that occurs from using the perceptual characteristics of a stimulus to orienting attention using its conceptual meaning.

▼ In this thesis, detailed solutions are presented to several problems dealing with geometric shape and orientation of an object in the field of robotics and automation. We first have considered a general model for shape variations that allows variation along the entire boundary of an object, both in two and three-dimensional space. Based on this model of shape variation, we have studied the problem of
orienting planar parts. We have focused on
orienting a planar imperfect part with pushing by placing a single friction-less line like jaw in different orientations. We then have shown how the family of possible parts defined by this model can be simultaneously oriented into the smallest possible interval of final orientations after applying a bounded predetermined number of pushes. We have considered the same model and investigated the locus of the center of mass for parts with shape variation. We have considered parts with uniform mass distribution and bounded the location of the center of mass for both two and three-dimensional cases. Pose statistics is a fundamental topic related to part
orienting. We have considered a family of 3D objects whose initial pose is uniformly random. We assumed that the object falls onto a flat surface in presence of gravity under quasi-static conditions. We defined a type of geometric eccentricity and showed that 3D eccentric objects with high probability rest at a pose, which is close to a specific plane or specific line. In this work, we also investigated a novel type of geometric probing. The goal is to interactively determine geometric shape and orientation of an unknown objects by using special measurements. We have defined a type of proximity probing which returns the distance to the boundary of the object in question. This work has concentrated on the case where the object is a convex polygon P in the plane. The goal is to find an upper bound on the number of measurements required to exactly determine P. We have proposed an algorithm that the number of requiring probes is linear in the number of vertices. Furthermore, our method is computationally very efficient, requiring only constant computation time per probe, for a total linear time complexity. We also considered the same task of using these proximity probes to identify P, but from a finite set of convex polygons. We presented an algorithm achieving this and bound the number of probes.

▼ Selective attention may be an effective strategy for
regulating emotions. The current study measured selective attention
to emotional pictures in healthy adults using a novel computerized
task. Participants saw pictorial cues on the right or left of the
screen, followed by target words on the same or opposite side.
Participants were divided into two groups. The suppress group had
to avoid looking at pictures (cues), whereas the attend group had
to look at them. Both groups categorized targets as indoor or
outdoor words. Subsequent cue/target recognition tests were
administered. Performance on both tasks was assessed by picture
valence, revealing reduced inhibitory control to negative picture
and difficulties reorienting to negatively cued locations. These
findings contribute to our understanding of affective-attentional
interactions in healthy adults. Moreover, the apparent inability to
avoid looking at negative items may highlight a need to explore
other emotion regulation techniques.

▼ Prompted by oculomotor theories of attention, the
present experiments explore the role of saccade activation in the
generation of two cueing effects: exogenous capture (Experiment 1)
and inhibition of return (IOR; Experiment 2). Exogenous capture is
shortlived and marked by faster responding toward recently
stimulated locations, whereas the longer-lasting IOR manifests as
slower responding toward those locations. Within each experiment,
Group A performed in a dual-task in which on most trials a
peripheral target had to be identified but infrequently a central
arrow probe called for an eye movement instead, while for Group B
the tasks were the same except saccade trials were frequent and
target identification trials were infrequent. In Experiment 1, for
group A uninformative cues captured attention as measured by faster
digit identification at the cued location, an effect not
accompanied by saccade activation. For group B, cues generated
saccade activation without capturing attention. Thus saccade
activation need not accompany exogenous covert capture, and covert
capture need not accompany saccade activation. In Experiment 2,
group A exhibited IOR which slowed digit identification, but did
not affect saccadic responding, while Group B exhibited no IOR in
either digit identification or eye movement trials. This finding
provides converging evidence that IOR can be dichotomized into two
forms; one which delays motor production itself (Evidenced amply
elsewhere, e.g., Taylor & Klein, 2000) and another which delays
responding by applying inhibition at a perceptual-motor interface
which can operate in independence from its motoric
cousin.

▼ This dissertation presents a novel behavioral task of lateralized attention: the speeded Lateralized Attention Network Task (sLANT) and establishes behavior and ERP features of single and multiple test administration. In addition, EEG Biofeedback was implemented in a double-blind, randomized, placebo controlled experiment contrasting the effects of EEG training protocols on hemispheric attention as measured by the sLANT. EEG Biofeedback mechanisms were also investigated. Protocols were selected to contrast training hemisphere (C3 vs C4) and reward frequency (SMR: 12-15 Hz, Beta: 15-18 Hz) with active placebo training. Significant protocol by session effects on performance Accuracy and ERP features demonstrate EEG Biofeedback has an effect beyond "Sham", has specific protocol effects by training hemisphere and frequency, and can be successfully blinded in a research context.

▼ This thesis reviews existing models of habituation of the orienting response
(OR) and presents four experiments designed to clarify contentious issues in the
existing literature. A new connectionist model of habituation is developed and
its performance in various experimental situations simulated.
Models created to account for habituation can be classified into two types:
1)Comparator models in which the subject compares an internal trace of past
stimulation with current stimulation and the orienting response is an index of
the disparity between the two.
2) The dual-process model in which habituation is the result of two
independent processes of inferred habituation and inferred sensitisation acting
within the stimulus-response (S-R) pathway. A major difference between the two types of model is that comparator models
of habituation (Ohman, 1979; Sokolov, 1960; Wagner, 1981) postulate that the
internal trace encodes extrapolatory or temporally predictive information about
the stimulus series, while the dual-process model (Groves & Thompson, 1970)
does not suppose that temporal information is encoded. Both the elicitation of
a response by stimulus omission, and the effect of 1ST variability on the rate of
habituation, are vital indicators of the merit of each approach. Only if both
phenomena are demonstrated to exist must a valid habituation model
incorporate a mechanism of temporal encoding.
Prior evidence for a response to stimulus omission and an effect of 1ST
variability on rate of habituation was inconclusive. Four experiments were
conducted to examine these and related phenomena in habituation of the skin
conductance response (SCR). It was concluded, from the results of these
experiments, that both response to stimulus omission and an effect of ISI variability on the course of habituation had a significant effect at short ISIs (1-
2s) but no significant effect was at longer ISIs (>10s).
A model of OR habituation was devised that was capable of incorporating the
new results as well as other published results. A neural network or
- connectionist modelling framework was chosen for this purpose, for its
quantitative nature, ease of simulation and neurobiological plausibility. Five
different connectionist models were constructed and simulations were
performed to assess the performance of each model in experiments testing
various temporal phenomena. It was concluded that a model incorporating
delta-rule learning of physical features plus learning of temporal relationships
by the learning of the interval between stimuli could most satisfactorily
simulate the observed empirical results. The connectionist models and their
performance in experimental simulations were related to traditional models of
habituation.

▼ Parts
orienting is an important part of automated manufacturing. Sensorless manipulation has proven to be a useful paradigm in addressing parts
orienting, and the manipulation of deformable objects is a growing area of interest. Until now, these areas have remained separate because existing
orienting approaches utilize forces that if applied to deformable parts violate the assumptions used by existing algorithms, and could potentially break the part. We introduce a new algorithm and manipulator actions that, when provided with the geometric description and a deformation model of choice for the part, exploits the deformation and generates a Plan that consists of the shortest sequence of manipulator actions guaranteed to orient the part up to symmetry from any unknown initial orientation and pose. Additionally, the algorithm estimates whether a given manipulator is sufficiently precise to perform the actions which guarantee the final orientation. This is dictated by the particular part geometry, deformation model, and the manipulator action path planner which contains simple end-effector constraints and any standard motion planner. We illustrate the success of the algorithm with multiple parts through 192 trials of experiments that were performed with low-precision robot manipulators and six parts made of four types of materials. The experimental trials resulted in 154 successes, which show the feasibility of deformable parts
orienting. The analysis of the failures showed that for success the assumptions of zero friction are essential for this work, increased manipulator precision would be beneficial but not necessary, and a simple deformation model can be sufficient. Finally, we note that the algorithm has applications to truly sensorless manipulation of non-deformable parts.

▼ This dissertation brings the insights of linguistic discourse analysis, and particularly of Systemic Functional Linguistics (SFL), to bear on the prophetic book of Joel in order to clarify the nature and function of the Day of YHWH in the book. The concepts of register and genre as defined by SFL, along with the related concepts of context of situation, context of culture, and context of text (or co-text), provide helpful tools that both dovetail with the problems and goals of other kinds of synchronic analysis and give new and valuable insights. By applying register analysis to the various passages that deal with the Day of YHWH in the book of Joel, the dissertation identifies the registers of the four sections of the book and compares and contrasts the various registers of each of these sections, making use of this analysis to shed light on the nature and function of the Day of YHWH in each section. Following this is a description of the linguistic register, the context of situation, and the nature and function of the Day of YHWH in the book of Joel as an entire text. The Day of YHWH in the book of Joel is a future moment of theophanic intervention, an inevitable day of destruction and salvation. Key to the theology of the Day of YHWH in Joel is the relational orientation of the readers/hearers of the book to YHWH. The book of Joel is thus a communicative act that calls for repentance grounded in worship of YHWH and that promises deliverance from the Day and a glorious eschatological future for those who heed the book's call to proper orientation toward YHWH.

▼ In a series of four studies, relationships between the auditory evoked cardiac response (ECR) and event-related potentials (ERPs) were examined, in an attempt to identify similarities between measures found important in the autonomic orienting reflex (OR) context and the ERP literature. The phasic evoked cardiac response (ECR) produced by innocuous stimuli requiring cognitive processing may be described as the sum of two independent response components. An initial heart rate (HR) deceleration (ECR1), and a slightly later HR acceleration (ECR2), have been hypothesised to reflect stimulus registration, and cognitive load, respectively. Two ERP components consistently linked to the processes thought to be represented by the ECR, are the N1 complex and Late Positive Complex (LPC). Therefore, the ECR, and N1 and LPC ERP measures, were systematically investigated in this thesis using varying manipulations of stimulus intensity and cognitive load to elucidate these putative relationships, based on the association of the ECR with preliminary OR processes in Preliminary Process Theory (Barry, 1984a, 1987a, 1987b, 1996, 2006, 2009). As expected, the phasic ECRs observed throughout this thesis were multiphasic (deceleration-acceleration) responses, reflecting stimulus parameters and situational factors. Following the methodology of previous research, components of the ECR were operationally separated by using conditions varying stimulus significance, allowing relationships to be drawn between components of the ECR and individual aspects of stimulus processing (Barry, 1982, 1984; Barry and Tremayne, 1987). The ECR1 was observed to be relatively invariant to stimulus parameters, and was thus taken as an index of stimulus registration; the ECR2 was observed in tasks with stimulus significance (i.e. Count vs. No Count), and was interpreted as reflecting increased cognitive processing demands. For the N1 complex, stimulus intensity and minor cognitive load effects were observed, indicating this component is an unlikely index of stimulus detection/registration. However, the effects observed for the LPC indicate that this complex is closely associated with the processing indexed by the ECR2, and was supported by significant correlations between these two measures. In addition, a new cardiac response form was found which challenges the current interpretation of ECR2. This was unable to be explored here, but offers exciting perspectives for future work.

▼ The spatial allocation of attention is a fundamental process that allows us to detect relevant behavioural stimuli, and involves both the engagement and disengagement of attention. The prefrontal (PFC) and posterior parietal (PPC) cortical regions have been identified as central nodes in a network for allocation of spatial attention. Additionally, these regions are modulated by the neurochemical acetylcholine. In this thesis, I investigated the neural underpinnings of engaging and disengaging spatial attention in rats, with a focus on the role of cholinergic input into the neocortex, including the PFC and the PPC. In the first experiment (Chapter 3), local field potentials in both the PFC and PPC, during the 5-choice serial reaction time task (5-CSRTT), were modulated by cholinergic cortical deafferentation. Specifically, successful target detection was associated with increased PFC-PPC coherence in the beta frequency during the preparatory pre-target period and with the increase in the PPC beta power. Both of these neural responses were attenuated after cholinergic deafferentation of the neocortex, which was also accompanied by a performance decrement. However, the 5CSRTT does not allow an independent examination of the attentional engagement and disengagement. Therefore, I created a cross-modal cued target detection (CTD) task to assess both the overt (Chapter 4) and covert (Chapter 5)
orienting of attention. There was a decrement in the PPC beta power during the disengagement of attention and an associated attentional impairment in rats with cholinergic cortical deafferentation. Conversely, there was increased PFC beta power in both groups during the successful engagement of attention. Thus, the CTD experiments demonstrated that cholinergic innervation of the PFC was not critical for the engagement of attention, but was critical in the PPC for the attentional disengagement. In sum, I used behavioural, electrophysiological, and pharmacological methods to dissociate the neural underpinnings for the engagement and disengagement of attention.

▼ Endogenous orienting occurs when a meaningful cue, such as an arrow, is used to direct attention toward a peripheral target. Adults and children as young as four years of age respond faster to a target that is cued by a central arrow than to
an uncued target. However, the nature of the understanding of the arrow by young children is not well understood. Young children may look in the proper direction based on the “weighted” nature of the arrow, or the fact that an arrow is perceptually
“heavier” on one side than the other. If this is the case, then young children do not necessarily need to understand the symbolic nature of an arrow in order to direct attention to a target. In this project, three- to five-year-old children were tested
using various centrally located arrow cues to test the hypothesis that as development progresses, there is also a progression of understanding of arrow cues from a perceptual to a symbolic understanding. The results did not support the hypothesis, but
future research must be done to investigate the understanding that young children have of important directional cues such as arrows.

▼ After multiple pairings of a cue and a rewarding event, animals will begin to attend to both the reward and the cue. Reports from Brown and Jenkins (1968) first described pigeons that began to track key lights predictive of food reward. Subsequently the phenomenon of conditioned cue approach has been reported across a variety of species including pigeons, quail, rats, monkeys, and stickleback fish (Brown and Jenkins, 1968; Cetinkaya and Domjan, 2006; Holland, 1977; Jenkins and Rowland, 1996; Sidman and Fletcher, 1968). More recently, investigations of individual differences in the expression of these behaviors have begun, as well as exploration into how these differences relate to other cognitive and neurological variations (Lesaint et al., 2014; Lovic et al., 2011; Meyer et al., 2012; Paolone et al., 2013). The objective of this dissertation was to characterize individual differences in rats’ propensity for
orienting towards a light-cue predictive of reward. I also aimed to describe how these differences related to the behavior’s vulnerability to memory updating, extinction learning, a variety of cognitive functions, and behavioral and neurological responses to drug challenge. I report that all rats showed conditioned approach toward the site of food-reward delivery, but only a subset also showed robust rearing and/or
orienting toward a light predictive of food (Orienters). Those rats that showed only conditioned reward approach were termed Nonorienters. Following memory update procedures, Orienters were more likely than Nonorienters to attenuate conditioned food approach, though conditioned rearing remains unaffected. Orienters were also more likely to make impulsive and risky decisions, enter a novel and risky environment, and be distracted during an attention assay. They also emitted more ultrasonic vocalizations than Nonorienters when exposed to amphetamine. Moreover, while both Orienters and Nonorienters preferred a context previously paired with drug to a context paired with saline, Orienters emitted more ultrasonic vocalizations during the preference test. Finally, while Orienters and Nonorienters showed behavioral differences after amphetamine injection, these differences were not reflected in the activity of the brain regions responsible for the conditioned
orienting response. Overall, these findings suggest that Orienters are more apt to memory update, make more impulsive and risky decisions, are more vulnerable to distraction, and that amphetamine has more impact upon the behavior of Orienters.

▼ This study investigates the sorting and orientation of silverware in commercial dishwashing applications. The purpose of this research was to investigate means to effectively sort and orient mixed silverware, piece by piece. The challenge was to efficiently lift silverware pieces off a magnetic conveyor, accurately sort them, and orient them into their respective collection bins. It was desired to have high accuracy, repeatability and reliability while operating at speeds to process at least 30 pieces per minute of mixed clean and unclean knives, spoons, forks and soupspoons. The method of study was primarily experimental. An efficient, accurate and reliable mechanism for sorting and
orienting silverware has been designed, developed and tested. Lifting mechanisms powered by solenoids has been successfully incorporated to lift silverware off magnetic conveying blocks. An
orienting mechanism powered by solenoids has also been incorporated to place differently oriented silverware in different collection bins. Suitable DAQ boards were used in the system to interface with the computer. Software was developed for a PC to interface with an existing machine vision identification and inspection system, and send and receive controlling signals to the various components, employing a specially constructed power supply. Experimental results demonstrate that the accuracy of sorting of the Silverware Sorting and
Orienting Machine in a stand-alone mode was 98.20%; accuracy in
orienting the silverware was 100% at processing rates up to 55 pieces/min. In co-ordination with the vision-based identification and inspection system at a processing rate of 45 pieces/min, the accuracy of sorting was 98.00%; accuracy in
orienting the silverware was 100%.

▼ Visual attention can be allocated to different locations of the visual field at different times resulting in improved processing of stimuli presented then and there. Understanding how attention is deployed is important due to its involvement in how we perceive and interpret the external world. The
orienting of attention, both voluntarily and involuntarily, in response to presentations of different stimuli is investigated in the current dissertation. Chapter 1 investigated how attention is oriented in response to feature cues predicting the timing and location of a subsequent target when observers have prior knowledge of where targets are likely to appear at different times. Results show that observers can flexibly incorporate the different types of predictors in service of their task. Chapters 2 and 3 investigated whether unconsciously processed objects can attract attention involuntarily when object categories are relevant to task goals. Chapter 2 uncovered an attentional cost when stimuli with unconsciously processed category membership information were presented than when control stimuli were presented. This behavioral cost was dependent upon the category information being related to the task performed. Chapter 3 further investigated the attentional cost and demonstrated attentional capture in a temporal paradigm – showing that attention was not reallocated following unconsciously processed category information. Together, the three studies expand our understanding of how attention is oriented, both voluntarily and involuntarily, based upon task set and different types of predictors. The dissertation stresses the importance of considering the context of the experimental task when interpreting results.

▼ Attentional biases to threat are thought to arise from anxiety promoting automatic attentional processing in the form of hypervigilance, while disrupting voluntary attentional processes such as inhibitory control. There is little support for the latter in specific fear. The current study examined behavioural (RT and accuracy) and electrophysiological correlates of hypervigilance (P1 amplitude) and inhibitory control (N2 amplitude) in 15 high and 15 low spider fear females aged 18-40 years using a modified flanker go nogo task with increased cognitive load. Spider or flower go targets were flanked by incongruent images or neutral dashes. A central mushroom appeared on nogo trials, and could be flanked by either spider or flowers. High fears did not show faster RTs and greater P1 amplitude in response to spider targets as hypothesised, with both groups showing greater RTs to spider targets, and low fears demonstrating reduced P1 amplitude in the left hemisphere. Contrary to predictions, there was no fear-specific behavioural interference or reduced nogo-N2 amplitude in high fears, but they did show increased N2 amplitude on trials with spider flankers. This may suggest a compensatory inhibitory mechanism in response to feared stimuli. However, the current paradigm may not have adequately elicited automatic attentional processing or fear responses.

▼ The selective deployment of attention over time optimises our perception and action at the moments when relevant events are expected to happen. Such "temporal orienting" to moments when something is going to happen is especially useful when this information can be combined with predictions about where and what events are likely to occur. A large body of research has already established how temporal predictions dynamically influence our perception and action, but questions remain regarding the neural bases of these attentional mechanisms. In this thesis I present three magnetoencephalography (MEG) studies that I conducted to investigate anticipatory neural dynamics associated with spatial-temporal orienting of attention for perception and action. I also investigate and discuss how such anticipatory dynamics change with ageing and neurodegeneration in Parkinson's disease (PD), and how these anticipatory neural dynamics behave in situations where a complex, hidden spatial-temporal structure is present. In Chapter 1, I introduce the topic of this thesis by reviewing the literature on temporal orienting of attention and by introducing my specific research questions. In Chapter 2, I present an MEG study on anticipatory neural dynamics of joint spatial-temporal orienting of attention in the visual domain, in younger and older adults. This study shows that neural dynamics with spatial, temporal and spatial-temporal orienting are all differentially affected by ageing. In Chapter 3, I describe an MEG experiment that investigates anticipatory neural dynamics during spatial-temporal motor preparation and compares PD participants to healthy control participants. This study reveals that both behavioural and neural dynamics with temporal orienting are affected in PD. In Chapter 4, I describe an experiment that explores how an implicit spatial-temporal structure is utilised to predict and prepare for upcoming actions. This study shows that motor cortical excitability is dynamically modulated in anticipation of the location and timing of events, even when such expectations are hidden in complex visual-motor sequences that remain largely implicit. In Chapter 5, the General discussion, I place these results in their wider context and discuss limitations and future directions.

▼ This study examined the relationship between 6-month old infants' orienting response to maternal arm-restraint (as measured by bradycardia), the quality of mother-infant communication at 6 and 9 months (as measured by the Relational Coding System) and attachment at 12 months (as measured by the Strange Situation Procedure). As positive mother-infant communication increases, the chances the infant will experience bradycardia increases. As negative mother-infant communication increases, the chances that the infant will experience bradycardia decreases. For mothers and infants who have more positive communication patterns, orienting response to the maternal arm-restraint suggests that maternal disruption of infant activity was a novel experience for them. This study suggests that mother infant interactions create an expected pattern of behavior for infants. When these expectations are violated, the infant has a physiological reaction that suggests increased attention to the disrupted interaction. Bradycardia at 6 months was not related to attachment at 12 months; however, considering both the physiology and environment of the infant, dyadic positive and negative interactions affect the quality of the mother-infant relationship several months later.

▼ A functional and effective alarm signal is a critical component of alarm systems designed to alert workers of impending danger. In a previous study (Hansson, 2017) background alarm sirens composed of changing-state sounds with an embedded temporal deviant, produced greater disruption of serial short-term memory than a signal without a deviant. However, to give rise to disruption the siren needed to change from fast to slow, since a change from slow to fast was impotent in its effect on task performance. In the current study, whether acoustic change was a necessary prerequisite for obtaining the fast-to-slow deviant effect was explored. Thus, repeated tones—steady-state sequences—presented at slow or fast rates were used with or without a temporal deviant (change from slow-to-fast vs. change from fast-to-slow). In the context of the steady-state sequences, both slow-to-fast and fast-to-slow temporal deviants produced disruption relative to the fast and slow control sequences. This suggests that a changing-state sequence is required for the fast-to-slow temporal deviant effect to arise. However, an alternative explanation based upon inter-stimulus intervals is also entertained. Understanding the acoustic parameters of sound is necessary to develop alarms sirens that are better at capturing attention. The current study suggests that embedding temporal deviants within sirens can promote greater attentional capture, but that this may depend on the nature of the alarm signal (whether it is changing vs. steady-state) and the direction of the change of speed (slow-to-fast vs. fast-to-slow).

▼ Alarm signals such as sirens are crucial in alerting users of impending dangers. Therefore, it is important that the siren is designed so it can capture user's attention. In a previous study (Hansson, 2017) background alarm sirens composed of changing-state sounds with an embedded temporal deviant, produced greater disruption of serial short-term memory than a signal without a temporal deviant. However, to give rise to disruption the siren needed to change from fast to slow, since a change from slow to fast was impotent in its effect on task performance. This was further addressed in Hansson (2018) where it was shown that acoustic change appeared to be a necessary prerequisite for obtaining the fast-to-slow temporal deviant effect: When steady-state sounds were used fast-to-slow and or slow-to-fast temporal deviants were equally disruptive of serial recall. However, in order to create a steady-state siren, inter-stimulus intervals were incorporated into the siren to prevent the continuous uninterrupted presentation of a single tone. Since inter-stimulus intervals were not used in Hansson (2017) it could be the presence of these that eliminated the potency of the fast-to-slow over the slow-to-fast temporal deviation effect in Hansson (2018). Therefore, the current study was undertaken to investigate whether the embedding inter-stimulus intervals within a changing-state siren would restore the potency of the fast-to-slow temporal deviation over the slow-to-fast temporal deviation in capturing attention. The additional disruption for fast-to-slow temporal deviants over slow-to-fast temporal deviants (that did not produce disruption relative to control) returned in the current study when inter-stimulus intervals were included within the siren. The results support the notion that the additional disruption produced by fast-to-slow, over slow-to-fast temporal deviants depend on the changing-state properties of the siren. Implications of this result for the design and operation of sirens within ecologically valid settings are discussed.

▼ In order to successfully interact with the environment, animals need to produce accurate movements towards specific positions in space. A crucial region of the brain that guides such goal-oriented movements is the superior colliculus (SC), an evolutionary conserved structure of the midbrain. While several lines of research in different model organisms have confirmed that the SC contributes to the initiation of orienting movements, how functionally distinct neuronal groups within the SC are organized to support the production of such motor outputs is poorly understood.
One of the reasons why the intrinsic circuit organization of the SC remains elusive is the lack of genetic characterization of the neuronal populations of the motor SC. Here, we performed RNAseq to screen for genetic markers for neuronal subpopulations in the motor SC. We identified a transcription factor, Pitx2, which is exclusively expressed in a subpopulation of glutamatergic neurons in the motor domain of the SC. Strikingly, this population of neurons displays a non-homogenous distribution within the motor layer of the SC, being organised in clusters along the mediolateral and anteroposterior axis. We mapped the pre-synaptic network and the post-synaptic targets of Pitx2ON neurons, unveiling that this modular population receives direct inputs from motor and sensory cortical regions, as well as several midbrain nuclei involved in movement control, and sends projection along the cephalomotor pathway. We then asked whether these modules may act as functional units, each integrating multimodal sensory information and encoding a specific feature of head movement, the main ethologically relevant orienting behaviour in rodents. Optogenetic activation of this modular population in freely moving animals produced a stereotyped, robust head motion characterised by a pronounced quantal nature; furthermore, the amplitude of the elicited head movement varied based on the modular unit activated. Our results suggest that distinct clusters of genetically defined neurons produce head displacement along a characteristic vector.
In conclusion, we found that a population of premotor neurons in the SC is organised in a modular conformation and we suggest that such modularity may represent a physical implementation of a discontinuous motor map for orienting movements encoded in the mouse SC. Our work complements previous observations of periodicity in SC circuitry, as well as its afferent and efferent systems. Exploiting the genetic toolkit available in the mouse, our work begins to address the functional relevance of this modularity and paves the way for future experiments to investigate principles of sensorimotor integration in SC circuits.

▼ Arrows are very commonly used as directional indicators for both adults and children. Research has found that children are cued to look faster when cued by valid vs. invalid arrow. Yet, for such a common directional symbol, it is still
largely unknown how children understand this directional indicator. They may be using the symbolic meaning of the arrow, or perhaps children are cued by more perceptual aspects like the visual weight of the arrow. This study presented children with 10
various arrow stimuli that differed in direction and distribution of weight. We asked children to use the arrow cue to find a hidden animal and recorded their eye movements as they were exposed to the various stimuli. Our results indicated that children
3 years and older were cued to look to the side indicated by the weight of the arrow but not to the side indicated by the direction. Children younger than 3 years of age were not cued by the weight or the direction of the arrow. These findings are
consistent with past research on this topic and may have implication for the understanding of abstract symbols in general, such as written language.

▼ This is a thesis that is
manuscript-based.
Using orthogonal subtractions of performance in
selected conditions the attentional network test (ANT)
measures the efficacy of three isolable components of attention:
alerting, orienting, and executive control. This dissertation
evaluated: 1) the relationship between these attention networks and
absentmindedness measured by the Cognitive Failures Questionnaire
(CFQ) and 2) stability, isolability, robustness, and reliability of
the two versions of the ANT (Fan et al., 2002 and Callejas et al.,
2005) with young adults and older adults and of the child version
of the ANT (Rueda et al., 2004) with young children when tested
over 10 sessions. A greater degree of absentmindedness as measured
with CFQ was associated with a greater alerting network score in RT
and with a greater orienting network scores in error rate when the
ANT-I was used. However, a greater degree of absentmindedness was
associated with a smaller orienting network score in error rate
when the ANT was used. These results suggest that the alerting and
the orienting networks are related to absentmindedness. However,
the orienting networks in the two ANTs were related to
absentmindedness differently which supports the proposal (Klein,
2009) that there are fundamental differences between attention when
controlled endogenously (ANT) as opposed to exogenously (ANT-I).
For young adults and older adults, all network scores in RT
remained robust even after nine previous sessions despite some
practice effects especially in the executive network both with the
ANT and the ANT-I. There was some evidence that the networks do not
operate independently in all situations. As expected, reliability
increased as more data are added. For young children, only the
alerting network scores remained robust over time. Learning effects
were observed only with the executive network. The reliability was
poor even when more data were added. This made it difficult to
assess the isolability of the network scores. The ANT and the ANT-I
were associated to the CFQ scores in a limited way. The ANT and the
ANT-I can be used for applications requiring repeated testing, but
the child ANT may not be suitable for such purpose.
