▼ The primary intent of this study was to gain insight into children's ability to use visual information in planning reaching movements. More specifically, the work presented here examined, from a developmental perspective, the use of visual information to use a) egocentric cues, b) allocentric cues, and c) the combination, in the form of visual background around a target. Children representing the age groups 5-, 7-, 9-, 11 years and adults participated in three experiments. All experiments were conducted using an immediate (visually-guided) and response-delay (memory-guided) paradigm. Experiment 1 examined the ability of participants to use an egocentric frame of reference to estimate reach via motor imagery. Results indicated that introducing a >? 2s delay affected responses in all age groups, especially the younger age groups (5- and 7-year-olds). As delay increased, children as a group tended to overestimate, while adults underestimated. Experiment 2 investigated how participants used allocentric cues to estimate the location of objects in a perceptual estimate paradigm. Results revealed that introducing a delay affected the estimation of distance among all age groups, with greater effect on the younger age groups. Experiment 3 examined how a visual background surrounding a target would affect estimation of reach. Results revealed that there were no differences when targets were surrounded with or without a background. Results also showed that the 5- and 7-year-olds were most affected on their perception of reach and estimates by longer delays. Considered together, these results hint that: (1) there is a significant temporal constraint on the representation of movement through the visoumotor stream, especially with children 7 years and younger, and (2) children as a whole tend to operate and rely more on an egocentric frame of reference; therefore, responses of reachability and distance estimates were susceptible to greater error when performed after a 2s delay.

▼ Successful navigation requires interactions among multiple but overlapping neuralpathways mediating distinct capabilities, including egocentric (self-oriented, route-based) andallocentric (external, map-based) learning. Multiple neurotransmitters are involved in bothnavigation types, including dopamine. These studies sought to elucidate the region-specific roleof dopamine in egocentric and allocentric learning.The dopaminergic-rich dorsal striatum (dStr) is involved in both egocentric andallocentric navigation. We first tested whether dStr dopamine loss using bilateral 6-hydroxydopamine (6-OHDA) injection impaired one or both types of navigation. Direct dStr 6-OHDA injection resulted in 80% dStr dopamine depletion pre- and post-testing. Two weeksafter 6-OHDA injections, rats began testing in the Cincinnati water maze (CWM) followed byMorris water maze (MWM), tests of egocentric and allocentric navigation, respectively. dStr 6-OHDA treatment significantly impaired CWM and MWM learning, but not MWM cuedperformance. These data support that dStr dopamine modulates both navigation types.The dStr is divided into two heterogeneous sub-regions, the dorsolateral (DLS) anddorsomedial (DMS) striatum. Both regions have been implicated in egocentric learning, with theDMS also involved in allocentric learning. We next tested how selective DMS or DLSdopamine loss via 6-OHDA injection would impact one or both types of navigation. Both DMSand DLS lesioned animals were significantly impaired in CWM, but not allocentric or cuedMWM performance. Dopamine loss in the DMS (62%) and DMS (75%) were region specificindicating independent roles for DMS and DLS dopamine in egocentric, but not allocentriclearning. While the DMS is involved in allocentric learning, these processes do not appear todepend on DMS dopamine.The nucleus accumbens (Nacc), another dopaminergic-rich striatal region, is involved inlearning. Nacc dopamine depleted rats (60%) were tested in either the CWM or MWM. Naccdopamine is implicated in reversal learning, thus this study tested allocentric reversal learningand egocentric reverse path CWM learning. Nacc dopamine depletion significantly impairedCWM, but not CWM reverse path performance. Lesioned animals were impaired in MWMacquisition, reversal, and cued trials. Off-target dopamine depletion in the dStr (20%) was at asub-threshold level to influence egocentric or allocentric learning indicating a Nacc specificdopaminergic modulatory role in both navigation types.Egocentric learning is dependent on the medial prefrontal cortex (mPFC), however therole of mPFC dopamine in egocentric learning has not been tested. 6-OHDA lesioned animalswere tested in the CWM followed by the MWM. mPFC dopamine depletion (88%) did not alterCWM or MWM learning. These findings suggest that while the mPFC is necessary foregocentric learning, it is not dependent on or modulated by mPFC dopamine.These data suggest independent roles for striatal sub-region (Nacc, dStr, DMS and DLS)dopamine involvement in egocentric learning. Allocentric learning is… Advisors/Committee Members: Vorhees, Charles (Committee Chair).

▼ Prostate cancer can be a difficult disease to manage but men who are diagnosed with it have networks of others around them who can be ready to offer support through the treatment. The effectiveness with which these networks can be mobilised is partly determined by the willingness of men to disclose their diagnosis. The main purpose of this research was to determine both the structure and content of the networks of men who have recently had a biopsy for prostate cancer. This qualitative study was conducted from an egocentric network perspective in which nodes and ties are fundamental features; nodes being the individuals or groups within a network and ties the relationships between them. All men who were on the waiting list for a prostate biopsy were eligible to be included in this study. A total of 41 men participated and completed a semi-structured interview that sought to elicit who were in the men’s networks and what was talked about. Particular emphasis was placed on the types of relationships together with the context in which they existed. Only 22 interviews from participants who received a positive biopsy were used for the analysis. A thematic analysis of the transcriptions enabled assessments to be made of which individuals and organisations were important and their relationships to the ego at this point in the medical process. The findings revealed that network structure is comprised of both general and health communication networks. General networks were those in everyday life and were determined by relationship status, employment status and geographical proximity of the men’s immediate family. Health communication networks were based around health issues and the factors which influenced these were men’s previous medical experience or whether they had medical professionals in their immediate family. Network content is the communication which occurs between individuals and the major theme concerns disclosure. The men’s decision about whether to disclose their prostate issues to others in their networks was based on the perceived presence of four factors in others: homophily, close proximity, strong ties and the professional or personal medical experience of others. Discerning if one or more of these factors were present in others, the men were increasingly likely to disclose about their own health. The second theme examined the tensions which existed between the benefits and barriers to disclosure. This depended on individuals and the context and were managed by the men when assessing each situation on a case-by-case basis. Theoretical implications of this research concern the recognition and functionality of health communication networks together with the four factors of disclosure. Future research would be focused around a longitudinal study to assess the dynamic nature of egocentric networks in responding to chronic illness. In addition, networks of single men and the value of siblings could be identified. Emphasis on the practical implications involve identifying and promoting favourable… Advisors/Committee Members: Oetzel, John G (advisor), Richardson, Margaret Ann (advisor).

▼ In the study of navigation, frequently it is assumed that navigation is accomplished using either an allocentric strategy based on a cognitive map, or an egocentric strategy based on stimulus response associations. Further, it is frequently assumed that individual navigators, or even entire genders, are only capable of navigating by one strategy or the other. The present study investigated whether individuals or genders were limited to a particular navigational strategy and whether both strategies might be learned or used at the same time. In the present study, undergraduate students were tested in a virtual Morris water maze that was modified to allow successful and efficient navigation using either an allocentric or an egocentric strategy. Learning trials on which the participants had to learn the location of the platform were alternated with probe trials on which participants would show which strategy they were using. At the end of testing, participants were given a series of tests to determine what knowledge they had acquired and which strategies they were capable of using. Results indicated that: a) most people preferred to navigate egocentrically in this maze, but some preferred to navigate allocentrically, b) people tended to use an egocentrically strategy first, but it was not a necessary step to learning to navigate allocentrically, c) people were better at their preferred strategy, d) people learned information about their non-preferred strategy, and e) those who preferred to navigate egocentrically could nevertheless learn to navigate allocentrically. Surprisingly, all of these results were true for both men and women, although women tended to prefer egocentric navigation at a higher rate than men, and men outperformed women when forced to navigate allocentrically. These results suggest it may be too simple to think of navigators as being capable of only a single navigational strategy or of learning only one strategy at a time.

▼ Advances in sensor miniaturization, low-power computing, and battery life have enabled the first generation of mainstream wearable cameras. Millions of hours of videos are captured by these devices every year, creating a record of our daily visual experiences at an unprecedented scale. This has created a major opportunity to develop new capabilities and products based on computer vision. Meanwhile, computer vision is at a tipping point. Major progress has been made over the last few years in both visual recognition and 3D reconstruction. The stage is set for a grand challenge that can break our field away from narrowly focused benchmarks in favor of “in the wild”, long-term, open world problems in visual analytics and embedded sensing. My dissertation focuses on the automatic analysis of visual data captured from wearable cameras, known as First Person Vision (FPV). My goal is to develop novel embodied representations for first person activity recognition. More specifically, I propose to leverage first person visual cues, including the body motion, hand locations and egocentric gaze for understanding the camera wearer's attention and actions. These cues are naturally ``embodied'' as they derive from the purposive body movements of the person, and capture the concept of action within its context. To this end, I have investigated three important aspects of first person actions. First, I led the effort of developing a new FPV dataset of meal preparation tasks. This dataset establishes by far the largest benchmark for FPV action recognition, gaze estimation and hand segmentation. Second, I present a method to estimate egocentric gaze in the context of actions. My work demonstrates for the first time that egocentric gaze can be reliably estimated using only head motion and hand locations, and without the need for object or action cues. Finally, I develop methods that incorporate first person visual cues for recognizing actions in FPV. My work shows that this embodied representation can significantly improve the accuracy of FPV action recognition. Advisors/Committee Members: Rehg, James M.

▼ Why do individuals engage in political economy egocentrically at some times and sociotropically at others? I claim that human beings will be more likely to demonstrate attitudes and behaviors that are in their own self-interest when in private, and those that are in the interests of others when in public. A survey of the research in mass political economy shows a major divide over whether individuals are selfish actors or hold strong motivations to benefit the collective. While there is merit to both of these approaches, neither is a panacea. Furthermore, I demonstrate that conflicting findings in existing research need not be concerning. These broad divisions in this literature mirror those within our brains. Natural selection has endowed our minds with strong capacities to behave both egocentrically and sociotropically. The real challenge becomes explaining what causes each of these parts of us to become active. This project is about how observability changes political behavior in predictable ways. Using data from multiple surveys across 23 countries, I am able to demonstrate the importance of social context across a diverse set of outcomes in political economy. First, while retrospective assessments of national economic conditions exert a strong and significant effect on candidate selection in public, they largely fail to do so in private. In the absence of others, individuals are more likely to reward and punish candidates based on their personal financial situation. Second, while individuals egocentrically update their attitudes of welfare policies when in private, they largely fail to do so in the added presence of an interviewer. Finally, in a unique online experiment of political donating behavior, I show that publishing respondent decisions in newspapers and on social media increases the propensity for individuals to benefit the country at costs to themselves. These findings hold major implications for how we participate in politics and the broader democratic process.

▼ A key goal in virtual reality (VR) is to provide the user with a first-person perspective of a virtual environment that feels every bit as real as the world around them. Achieving this goal is of great interest to fields such as architecture, where it would allow both the architect and their client to explore a space they are designing before it is built, and use its realistic presentation to aid in the decision making process. Careful attention has to be paid, however, to ensure that the virtual representation is faithfully portraying the same sense of space as the real world. Unfortunately, research has uncovered that using an egocentric point of view within virtual environments results in the users experiencing errors in their spatial judgment [Henry & Furness 93]. Specifically, from a user's perspective, objects in the virtual environment will appear closer than they really are. This poses a serious problem for using virtual environments as veridical representations, as the mismatches occurring between perceived virtual spaces and finalized designs would compromise any conclusions being made within the virtual reality system. This dissertation presents work that explores this misjudgment problem from a cognitive sense, one where we evaluate the effect that a user's sense of presence has in the virtual environment. Our experiments are grounded with an initial study, which finds that placing a user within a virtual environment that matches the real, physical space they occupy does not generate the same errors found in previous studies. Further experiments build off this discovery by exploring the beneficial aspects of co-location of the virtual space with the physical, and delving into the possible cues used in high-fidelity replicas that aid in a user's increased accuracy. In addition, we present work on how to increase the user's spatial accuracy in remote locations, which is the true goal of virtual reality. This research focuses on giving users additional feedback in the virtual world, through the use of full-bodied virtual avatars. With these additional cues, we grant the user the ability to form a better cognitive model of the virtual space, and start making significant headway into eliminating the distance compression problem.

▼ In daily life, people frequently perform various aiming movements, such as reaching or making a saccade toward a cellphone. The early stage for executing such movements is to localize the target location precisely. A visual target can be represented and maintained in memory in two main reference frames: egocentric (body-fixed) or allocentric (world-fixed). However, the neural mechanisms for the allocentric spatial processing are poorly understood and for the Allo-Ego conversion are still unknown in humans. This thesis investigated the allocentric and egocentric mechanisms with a focus on target memory coding for reaching (study 1) and saccades (study 2) in healthy humans using event-related functional magnetic resonance imaging (fMRI) designs where the phase of memorized target representation was separated from the phase of motor planning and execution. I further examined neural substrates for Allo-Ego conversion of targets for reach in study 3 using different types of cues to specify reach target direction for two reach tasks before delay or response phases. I observed widely overlapping cortical areas in the egocentric and allocentric reach tasks as compared to the control, but higher activation in parietofrontal areas for the former, and higher activation in early visual areas for the latter. Further, directional selectivity in egocentric coordinates (target relative to gaze/midline) was observed in superior occipital and inferior occipital gyrus; on the other hand, directional selectivity in allocentric coordinates (target relative to a landmark) was revealed in inferior temporal gyrus and inferior occipital gyrus. These results indicate that different cortical mechanisms are involved in the representations of remembered reach targets. I found similar pattern of task-relevant activation and egocentric directional selectivity in the saccade study. However, different areas from those observed in the reach study showed allocentric directional selectivity of remembered saccade targets including precuneus and midposterior intraparietal sulcus, suggesting effector-specific (eye vs. hand) neural mechanisms. In study 3, I identified four areas in parietal and frontal cortex, i.e., posterior precuneus, angular gyrus, supramarginal gyrus and medial frontal gyrus that are specifically involved in converting allocentric target coding to egocentric representation as soon as the final target location for reach is specified.

Previous human behavioral research has provided support for the existence of different frames of reference utilized during spatial processing that can be dependent or independent of the observer. These are known respectively as egocentric and allocentric frames of reference. However, it has been difficult to dissociate these two different processes under realistic conditions. Importantly, how these frames of reference are influenced by the visual and non-visual information is not well understood. Therefore, the studies of this thesis evaluated spatial processing utilizing realistic and ecologically valid stimuli in environments of different scales, while systematically manipulating the visual and non-visual information available during learning. We demonstrated that non-visual information generated by actively walking through an environment leads to more egocentric processing, whereas the same visual motion information presented passively via a video leads to more allocentric processing (Chapter 2). Further, characteristics of the visual scene can also influence how it is processed, dependent on the strength of the verbal identity of the features in the environment (Chapter 3). Specifically, in a small room environment subject’s representations of corners-to-corners (corners do not have an obvious verbal component) were not as strongly encoded relative to each other in comparison to objects-to-objects (objects with an obvious verbal identity ). Finally, we demonstrated differential influences of non-visual information dependent on whether the features in the visual scene were more allocentrically processed or egocentrically processed (Chapter Four). Specifically, when different features of layouts are made distinguishable by their identity, this lead to more allocentric processing whereas when different features are made distinguishable by their relative position, this lead to more egocentric processing. Further, non-visual information made available during spatial updating when the observer is changing viewpoints benefitted tasks focused on differentiating changes to objects’ identity and less so for differentiating changes in relative object position.

▼ This dissertation examines how changes in American society over the past four decades have shaped personal networks. Specifically, it uses survey data to assess changes in the personal networks of residents of northern California in 1977-8 and 2015-6. The dissertation is organized as three papers, each considering one key way that personal networks may have changed. The first paper examines the changing role of distance in the maintenance of personal ties. Contra popular suppositions that technology is making social interactions superficial or that technology is a panacea for social support, I find that people today are more selective about friends and family whom they rely upon, both ignoring those nearby more often and casting a wider geographic net for emotional support. I examine changes in relationships with siblings, friends, and mothers and fathers. Intimate supportive exchanges that were not strongly differentiated by proximity in the late 1970s were more likely to be conducted with individuals who live farther away by the mid-2010s. Compared to respondents of the late 1970s, mid-2010s respondents were also more likely to feel “especially close” to parents and friends who lived more than an hour away. As one may suspect, exchanges that require getting together, such as socializing or obtaining practical support, are still sustained by proximity. Overall, people use distance and technology together to exchange more with their most important ties, while allowing others to wither. The second paper asks whether women’s greater labor force participation has led to changes in the composition of their personal networks. I find that women have gained supportive work-related ties in the last four decades compared to men. For both time periods, I identify individuals associated with work who were also named as providers of four supportive exchanges: socializing, confiding, obtaining practical help, and asking for advice. Respondents could describe these individuals as coworkers, people who did the same kind of work, or people whom they had met at work. While women in the late 1970s lagged men in forming work-related supportive ties, women today have caught up with or surpassed men. Follow-up analyses support two explanations for the shift. First, women continue to largely befriend women, not men, at work; this suggests that some of the increase in women’s supportive ties at work can be attributed to the increased presence of women in the workplace. Second, compared to men today and to women of the late 1970s, women today who are not working are much more likely to interact with people associated with work. This suggests that women are better able than men to maintain work-related ties. Paper three considers whether changing gender roles and norms at home and at work have led men’s and women’s personal networks to become more similar. Demographic changes such as women’s increasing and men’s decreasing labor force participation and related cultural changes such as more egalitarian beliefs about the division of labor in…

▼ Brain-machine interfaces (BMIs) are the only currently viable means of communication for many individuals suffering from locked-in syndrome (LIS) – profound paralysis that results in severely limited or total loss of voluntary motor control. By inferring user intent from task-modulated neurological signals and then translating those intentions into actions, BMIs can enable LIS patients increased autonomy. Significant effort has been devoted to developing BMIs over the last three decades, but only recently have the combined advances in hardware, software, and methodology provided a setting to realize the translation of this research from the lab into practical, real-world applications. Non-invasive methods, such as those based on the electroencephalogram (EEG), offer the only feasible solution for practical use at the moment, but suffer from limited communication rates and susceptibility to environmental noise. Maximization of the efficacy of each decoded intention, therefore, is critical. This thesis addresses the challenge of implementing a BMI intended for practical use with a focus on an autonomous assistive robot application. First an adaptive EEG- based BMI strategy is developed that relies upon code-modulated visual evoked potentials (c-VEPs) to infer user intent. As voluntary gaze control is typically not available to LIS patients, c-VEP decoding methods under both gaze-dependent and gaze- independent scenarios are explored. Adaptive decoding strategies in both offline and online task conditions are evaluated, and a novel approach to assess ongoing online BMI performance is introduced. Next, an adaptive neural network-based system for assistive robot control is presented that employs exploratory learning to achieve the coordinated motor planning needed to navigate toward, reach for, and grasp distant objects. Exploratory learning, or “learning by doing,” is an unsupervised method in which the robot is able to build an internal model for motor planning and coordination based on real-time sensory inputs received during exploration. Finally, a software platform intended for practical BMI application use is developed and evaluated. Using online c-VEP methods, users control a simple 2D cursor control game, a basic augmentative and alternative communication tool, and an assistive robot, both manually and via high-level goal-oriented commands.

▼ Hintergrund: Sowohl schwere depressive Episoden als auch Alexithymie sind in Zusammenhang mit Empathie-Defiziten gebracht worden. Das exakte Wesen dieser Defizite blieb bisher jedoch unklar. In dieser Studie testeten wir, unter welchen Bedingungen depressive Patienten mit hohen bzw. niedrigen Alexithymie- Werten verminderte Empathie zeigen. Wir testeten Empathiefähigkeit insbesondere in solchen Situationen, in denen eine Inhibition des eigenen emotionalen Zustandes entweder notwendig oder nicht notwendig ist. Methoden: 29 zum Zeitpunkt der Testung stationär aufgenommener Patienten mit depressiver Episode (niedrige Alexithymie-Werte: n=11, hohe Alexithymie-Werte: n=18) sowie 42 gesunde Kontrollprobanden (niedrige Alexithymie-Werte: n=28, hohe Alexithymie-Werte: n=14) vollzogen einen Emotionale-Egozentrizitäts-Test, der auf taktiler Stimulation basiert. Dieser Test misst empathische Einschätzungen, indem er Situationen differenziert, in denen sich einerseits der eigene emotionale Zustand von dem des Anderen unterscheidet und somit die Inhibition des eigenen emotionalen Zustands gefordert ist, bzw. wenn andererseits dies nicht der Fall ist und die empathische Voraussage des emotionalen Zustandes des Anderen auf einem einfachen Projektionsmechanismus basieren kann. Um trait Empathie zu messen, verwendeten wir darüber hinaus den Interpersonal Reactivity Index-Fragebogen (IRI). Ergebnisse: Nur Alexithymie, nicht aber eine depressive Episode reduzierte Empathie in Situationen, in denen ein einfacher Projektionsmechanismus für eine empathische Einschätzung genügt. Wenn jedoch die Inhibition der eigenen emotionalen Situation gefordert war, zeigten depressive Patienten - unabhängig von Alexithymie - einen egozentrischen Bias bei der empathischen Einschätzung der emotionalen Situation des Anderen und einen altrozentrischen Bias bei der Einschätzung der eigenen emotionalen Situation. Das letztere Ergebnis weist auf eine möglicherweise erhöhte emotionale Ansteckbarkeit bei depressiven Patienten hin. Der IRI ergab erhöhten empathischen Stress bei Depressiven und eine positive Korrelation zwischen empathischem Stress (IRI) und dem altrozentrischen Bias im Hinblick auf alle Probanden. Ebenfalls im Hinblick auf die gesamte Probandengruppe reduzierte Alexithymie die Größe des egozentrischen Bias. Schlussfolgerung: Diese Ergebnisse legen nahe, dass depressive Patienten intakte basale empathische Fähigkeiten bieten, wenn ein einfacher Projektionsmechanismus für empathische Urteile gefordert ist und gleichzeitig keine Alexithymie vorliegt. In Situationen, in denen sich die eigene emotionale Situation und die des Anderen unterscheiden, sind depressive Patienten jedoch empfänglich für einen egozentrischen bzw. altrozentrischen Bias. Dies verweist auf ihre Schwierigkeiten sich empathisch in emotional inkongruente Situationen des Anderen hineinzuversetzen. Advisors/Committee Members: [email protected] (contact), m (gender), N.N.

▼ Impairments in hand function lead to reduced independence and quality of life after cervical spinal cord injury (SCI). In order to develop effective rehabilitation interventions for individuals with cervical SCI, it is important to assess hand function throughout the rehabilitation process. Currently, the efficacy of new treatments is measured by assessments limited to a controlled setting or based on self-report; there is currently no viable method to collect quantitative information once the patient has returned to the community. This thesis attempts to solve this gap by developing a computer vision-based wearable camera system for monitoring hand use. Our research involved (1) the collection of egocentric video that represents activities of daily living, (2) the development of an algorithm that captures interactions between the hand and objects in the environment, and (3) the evaluation of the system in both laboratory and home settings. Four studies were executed, involving three video datasets (20 able-bodied participants and 17 participants with SCI in a home simulation laboratory, as well as 3 participants with SCI in their home). We introduced the concept of hand-object interaction detection, defined as a binary decision about whether or not the hand is manipulating an object for a functional purpose. The datasets were used in the development and evaluation of an algorithmic pipeline consisting of hand detection and segmentation, followed by hand-object interaction detection. For this step, a random forest classifier was trained on hand motion, hand shape and scene colour features. The frame-by-frame binary output data over time was further analysed to extract three functional hand-use metrics: (1) the amount of total interaction as a percentage of testing time, (2) the average duration of interactions in seconds, and (3) the number of interactions per hour. The final study investigated the views of participants with SCI on the use of wearable cameras. With appropriate strategies determined by input from individuals with SCI, this thesis demonstrates the potential of a wearable egocentric camera as a unique tool to allow researchers and clinicians to gauge the user's level of independence at home in activities involving upper limb function.

▼

In this study, we describe and analyze six year olds symbolic systems: speech, drawing and writing as mediational cultural tools for the construction of knowledge in teacher/children, child/child and child/self interactions produced in classroom contexts of the first year of elementary school and in individual sessions. Our research used a qualitative approach to examine the educational processes considering the child in his/her singular process of development. Our thesis is that the free graphic productions, those relating to drawings and initial writing, both accompanied by the speech, are used by children as mediating cultural tools in the construction of knowledge and assessment of what is already known. We obtained our empirical information by observing the knowledge building process in the teaching and learning experiences of reading and writing in the first year of elementary school along 8 months in four audio and video recorded sessions in classroom context and in four session at individual moments with the researcher. The literacy activities of the sessions were: five story books recount, two free writing and one drawing and writing at home. We interviewed the mothers of those children and the teacher of the classroom to contextualize the drawing and writing childrens activities at school and at home. The results indicated also that the use of speech, drawing and writing acquired different functions; that the use of communicative speech among children as well as between the teacher and children in argumentative dialogues with developing knowledge generated ZPDs; and that egocentric speech functioned in order to organizing drawing and spelling of free writing activities. The use of egocentric speech acquired the following functions directed to generate knowledge in the construction of intersubjectivity: a) as a commentary of the social other; b) a commentary of the speaker himself directed to the social other; c) egocentric speech of the social other; d) an assessment commentary; e) egocentric speeches of collective spelling; f) as commentaries of agreement or disagreement. In addition, results indicated the use of drawing with the function of expressing knowledge about stories or other subjects being focused during the activities, relating it/them to other prior information, triggered by the stories or by the drawings, the scenes of a narrative, the physical elements and characters of a tale. And regarding writing, drawing worked as a scaffolding, when the scenes drawn were meant for the organization of written texts or as a mnemonic device to trigger the necessary knowledge for the writing on the subject drawn. Regarding drawing, we found the use of free writing with the task of naming or writing a story drawn, as well as writing with the function of mediating the content of the developed activities.

▼ Environments with people are complex, with many activities and events that need to be represented and explained. The goal of scene understanding is to either determine what objects and people are doing in such complex and dynamic environments, or to know the overall happenings, such as the highlights of the scene. The context within which the activities and events unfold provides key insights that cannot be derived by studying the activities and events alone. \emph{In this thesis, we show that this rich contextual information can be successfully leveraged, along with the video data, to support dynamic scene understanding}. We categorize and study four different types of contextual cues: (1) spatio-temporal context, (2) egocentric context, (3) geographic context, and (4) environmental context, and show that they improve dynamic scene understanding tasks across several different application domains. We start by presenting data-driven techniques to enrich spatio-temporal context by augmenting Bag-of-Words models with temporal, local and global causality information and show that this improves activity recognition, anomaly detection and scene assessment from videos. Next, we leverage the egocentric context derived from sensor data captured from first-person point-of-view devices to perform field-of-view localization in order to understand the user's focus of attention. We demonstrate single and multi-user field-of-view localization in both indoor and outdoor environments with applications in augmented reality, event understanding and studying social interactions. Next, we look at how geographic context can be leveraged to make challenging ``in-the-wild" object recognition tasks more tractable using the problem of food recognition in restaurants as a case-study. Finally, we study the environmental context obtained from dynamic scenes such as sporting events, which take place in responsive environments such as stadiums and gymnasiums, and show that it can be successfully used to address the challenging task of automatically generating basketball highlights. We perform comprehensive user-studies on 25 full-length NCAA games and demonstrate the effectiveness of environmental context in producing highlights that are comparable to the highlights produced by ESPN.

Depuis les vingt dernières années, l'industrie a développé plusieurs produits commerciaux dotés de capacités auditives et visuelles. La grand majorité de ces produits est composée d'un caméscope et d'un microphone embarqué (téléphones portables, tablettes, etc). D'autres, comme la Kinect, sont équipés de capteurs de profondeur et/ou de petits réseaux de microphones. On trouve également des téléphones portables dotés d'un système de vision stéréo. En même temps, plusieurs systèmes orientés recherche sont apparus (par exemple, le robot humanoïde NAO). Du fait que ces systèmes sont compacts, leurs capteurs sont positionnés près les uns des autres. En conséquence, ils ne peuvent pas capturer la scène complète, mais qu'un point de vue très particulier de l'interaction sociale en cours. On appelle cela "Analyse Égocentrique de Scènes Audio-Visuelles''.Cette thèse contribue à cette thématique de plusieurs façons. D'abord, en fournissant une base de données publique qui cible des applications comme la reconnaissance d'actions et de gestes, localisation et suivi d'interlocuteurs, analyse du tour de parole, localisation de sources auditives, etc. Cette base a été utilisé en dedans et en dehors de cette thèse. Nous avons aussi travaillé le problème de la détection d'événements audio-visuels. Nous avons montré comme la confiance en une des modalités (issue de la vision en l'occurrence), peut être modélisée pour biaiser la méthode, en donnant lieu à un algorithme d'espérance-maximisation visuellement supervisé. Ensuite, nous avons modifié l'approche pour cibler la détection audio-visuelle d'interlocuteurs en utilisant le robot humanoïde NAO. En parallèle aux travaux en détection audio-visuelle d'interlocuteurs, nous avons développé une nouvelle approche pour la reconnaissance audio-visuelle de commandes. Nous avons évalué la qualité de plusieurs indices et classeurs, et confirmé que l'utilisation des données auditives et visuelles favorise la reconnaissance, en comparaison aux méthodes qui n'utilisent que l'audio ou que la vidéo. Plus tard, nous avons cherché la meilleure méthode pour des ensembles d'entraînement minuscules (5-10 observations par catégorie). Il s'agit d'un problème intéressant, car les systèmes réels ont besoin de s'adapter très rapidement et d'apprendre de nouvelles commandes. Ces systèmes doivent être opérationnels avec très peu d'échantillons pour l'usage publique. Pour finir, nous avons contribué au champ de la localisation de sources sonores, dans le cas particulier des réseaux coplanaires de microphones. C'est une problématique importante, car la géométrie du réseau est arbitraire et inconnue. En conséquence, cela ouvre la voie pour travailler avec des réseaux de microphones dynamiques, qui peuvent adapter leur géométrie pour mieux répondre à certaines tâches. De plus, la conception des produits commerciaux peut être contrainte de façon que les réseaux linéaires ou circulaires ne sont pas bien adaptés.

Along the past two decades, the industry has developed several commercial products with audio-visual…

▼ The lack of college graduates, who possess a four-year degree, will soon impact the United States in a lack of knowledge workers needed to compete in the global economy. If current trends continue, California alone will be short one million college graduates by 2025. Despite college efforts to increase graduation rates only about half of students will complete a degree or certificate within six years. These numbers decline for underrepresented students. Many of these students start their college experience at a community college. Thus assisting students in the enrollment at a community college, the transfer process, and transition from a community college to a four-year university, are critical to increasing overall baccalaureate attainment rates. Transfer students face many of the same academic and social adjustment issues as first-time freshman without many of the same support programs. Students do not go through the transfer experience by themselves, therefore an emphasis of this study was on students??? interactions with those inside and outside institutions of higher education. A student???s social network and access to social capital, both on and off-campus plays a role in his or her ability to achieve success in the college environment. Underserved students often lack the social capital to access the required networks or level of knowledge needed to properly adjust to university life. This egocentric network analysis explored underrepresented transfer students??? experiences with their on-campus and off-campus social networks while transferring from a community college and post-transfer adjustment at a four-year institution. The results of this study provided insight on who students rely upon for support and information at the community college and university level. Although study participants did not have highly closed networks, their were robust and allowed participants to utilize ties when needed. As students moved through their college careers their on-campus network shift from family to peers, with academic advisers being utilized through out their college career. Off-campus networks were consistent with parents and spouses providing the most personal support and encouragement no matter the age of the student.

▼ Does the structure of an individual’s personal network effect their physical and mental health? Or does the structure of the network influence individual health by influencing the functions of the network or the individual’s health behaviors? In my dissertation, I examine these questions using two waves of nationally representative data from the National Social Life, Health, and Aging Project and employing conditional change models.In study 1, I examine the associations between network structure, network function, and health. I find no direct associations between baseline network structure and later health. However, I do find that baseline network structure is associated with later network function, which, in turn, is associated with health. I also find limited support for a feedback loop in which baseline health has effects on later network structure. Perceived social support may be more important for the health of older adults than network structure characteristics, but network structure is meaningful in that it provides the source from which support can be derived.In study 2, I examined the effects of spousal loss on depression across different levels of spousal support, including baseline network structure and network function to observe whether they served as a buffer to spousal bereavement. The findings revealed that losing a spouse was positively associated with the number of depressive symptoms, but only for those with highly supportive spouses. None of the network structure and function measures at baseline were associated with later depression. The findings imply that spousal bereavement in late life depends on how supportive the spouse was.In study 3, I examine the social network factors that influence health risk behaviors—specifically, cigarette use and alcohol consumption. Findings show that personal networks can have protective effects on smoking or drinking; however, for current smokers and drinkers, personal networks are enabling. Having more support and having health discussion partners reduced the adoption of health-compromising behaviors. In conclusion, health-compromising behaviors may not necessarily be adopted as a coping mechanism, but may be a pro-social activity that is increased when there are others in the network who also engage in similar activities.

We investigated 1) how objects come to serve as landmarks in spatial memory and more specifically how they form part of an allocentric cognitive map and 2) how humans encode multiple connected spatial environments. In both sets of experiments, participants performing a virtual driving task incidentally learned the layout of a town and locations of objects or stores in that town. Their spatial memory and recognition memory for the objects or stores were subsequently tested. To assess whether the objects were encoded allocentrically, we developed a new measurement, pointing consistency. We found that when participants had more limited experience of the environment spatial memory for objects at navigationally relevant locations was more consistent across tested viewpoints than for objects at navigationally less relevant locations. When participants’ attention was focused on the appearance of objects, the navigational relevance effect was eliminated, whereas when their attention was focused on the objects’ locations, this effect was enhanced, supporting the hypothesis that when objects are processed in the service of navigation, rather than merely being viewed as objects, they engage qualitatively distinct attentional systems and are incorporated into an allocentric spatial representation. The results were consistent with evidence from the neuroimaging literature that when objects are relevant to navigation, they not only engage the ventral “object processing stream”, but also the dorsal stream and medial temporal lobe memory system classically associated with allocentric spatial memory. Moreover, in the connected environments, our data were more consistent with the formation of local maps, regardless of whether the neighborhoods were learned together or separately. Only when all visible distinctions between neighborhoods were removed did people behave as if they formed one integrated map. These data are broadly consistent with evidence from rodent hippocampal place cell recordings in connected boxes, and with hierarchical models of spatial coding.
