Individuals with high functioning Autism Spectrum Disorder (ASD) stand an increased risk of experiencing mental health problems during adolescence. The present study aimed to develop a better understanding of interpersonal relationships in the lives of adolescents with high functioning ASD. Eight adolescents with a diagnosis of Asperger’s syndrome or ASD without an identified intellectual disability engaged in a structured interview based on a personal construct psychology exercise exploring constructs about interpersonal relationships. Interviews were transcribed and subjected to a thematic analysis. Four themes were identified: 1) Relationships as a source of support, 2) Perceptions of similarity and difference, 3) Valued qualities in self and others and 4) The development of and maintenance of relationships. Whilst this exploratory study highlighted some commonality in terms of perceptions of family support and friendships as protective and desirable, the participant group differed in their ability to establish and maintain peer relationships. However, peers were seen by participants as being very important in the development of social skills - a finding which has implications for the delivery of social skills training and other supportive interventions. The personal construct exercise provided an accessible and useful platform for the exploration of the social worlds of adolescents with ASD.

This study aimed to determine whether there are significant relationships between fibromyalgia syndrome (FMS), social cognition, and adult insecure attachments. It was also hypothesised that social cognition would mediate the relationship between insecure attachment style and FMS. A quantitative, cross-sectional design was employed to compare experiences of 105 individuals with FMS and 172 healthy controls (HC). A correlation and a mediation analysis were used to explore relationships between insecure attachment, social cognition, and FMS symptoms. Data were obtained via self-report measures filled in either in paper form or via on-line questionnaire. The relationships between anxious and avoidant attachment styles and FMS were confirmed. The significance of the relationship between social cognition and FMS varied depending on the measure used. When ability to recognise emotions in others was tested (Reading the mind in the eyes test) there were no significant differences between FMS and HC. However, the mentalization measure- Reflective Function Questionnaire, which additionally tests the ability to recognise one’s own feelings, showed a significant relationship with FMS. The relationship of FMS with both insecure attachment styles as well as with mentalization were strongly mediated by psychological distress. Social cognition was not shown to mediate the relationship between insecure attachment and FMS. Although causality cannot be inferred, psychological distress was strongly related to FMS and significantly influenced the way FMS is related to insecure attachment and poor social cognition. Implications for clinical practice and future research are discussed.

Autism is a behaviourally defined disorder. The impairments in social communication and repetitive behaviours are individually non-specific. The disorder has indistinct boundaries both with other psychiatric disorders and with normal personality types. At the cognitive level, groups of people with autistic disorder can be differentiated from people without the disorder by their ability to reason about beliefs and knowledge (Theory of Mind) and by tests of visual disembedding (central coherence). This study examined whether young people with some of the behavioural features of autism but not necessarily a diagnosis, would show this distinctive cognitive profile. In a sample of 60 young people with additional learning support needs, we found that those with high levels of autistic traits (n=40) showed the same cognitive profile as has been found in people diagnosed with autistic disorder. This supports the view that autism is an extreme on a continuum of cognitive traits. Given the highly heritable nature of autism, we hypothesised that the parents of the young people with autistic traits will also display these cognitive features. The results indicated that there was no difference between the groups of parents on an advanced test of social cognition. Parents of people with high autistic traits were more resistant to one of the visual illusions and saw fewer reversals of an ambiguous figure when IQ was statistically controlled. These results in a sample with a low genetic load suggest ambiguous figures will be important in delineating the broader cognitive phenotype of autism.

Faces communicate a wealth of information, including cues to others’ internal emotional states. Face processing is often studied using static stimuli; however, in real life, faces are dynamic. The current project examines face detection and emotion recognition from isolated motion cues. Across two studies, facial motion is presented in point-light displays (PLDs), in which moving white dots against a black screen correspond to dynamic regions of the face. In Study 1, adults were asked to identify the upright facial motion of five basic emotional expressions (e.g., surprise) and five neutral non-rigid movements (e.g., yawning) versus inverted and scrambled distractors. Prior work with static stimuli finds that certain cues, including the addition of motion information, the spatial arrangement of elements, and the emotional significance of stimuli affect face detection. This study found significant effects involving each of these factors using facial PLDs. Notably, face detection was most accurate in response to face-like arrangements, and motion information was useful in response to unusual point configurations. These results suggest that similar processes underlie the processing of static face images and isolated facial motion cues. In Study 2, children and adults were asked to match PLDs of emotional expressions to their corresponding labels (e.g., match a smiling PLD with the word “happy”). Prior work with face images finds that emotion recognition improves with age, but the developmental trajectory depends critically on the emotion to be recognized. Emotion recognition in response to PLDs improved with age, and there were different trajectories across the five emotions tested. Overall, this dissertation contributes to the understanding of the influence of motion information in face processing and emotion recognition, by demonstrating that there are similarities in how people process full-featured static faces and isolated facial motion cues in PLDs (which lack features). The finding that even young children can detect emotions from isolated facial motion indicates that features are not needed for making these types of social judgments. PLD stimuli hold promise for future interventions with atypically developing populations.

Social functioning impairments are a core, debilitating, and treatment refractory feature of schizophrenia. The mechanisms contributing to these impairments are unknown. Cognitive control mechanisms, mediated by the lateral prefrontal cortex (LPFC), are known to influence response to interpersonal stressors in healthy individuals, thus impairments in these processes may contribute to social deficits. Deficits in cognitive control and lateral prefrontal abnormalities are well-documented in schizophrenia, but the relationship between these deficits and social interactions has received limited attention in the literature. The current dissertation presents a systematic examination of the contribution of the behavioral and neural mechanisms of cognitive control to social functioning impairments in schizophrenia. Three papers are presented. / Psychology

This thesis examines the representation of disabled people in Western culture within the context of feminist theoretical analyses to compare images of disabled people with the representations of women's bodies that are found in cultural representations. The body of the thesis is comprised of six chapters which explore images of disability in six major cultural sites for such images: charitable advertising, popular women's magazines, literature for children, film, biblical narratives and pornography. My analysis of these sites suggests that there are parallels between the ways in which women's bodies and the bodies of disabled people are represented. In Chapter 1 I analyse the discourse of charity advertising and the ways in which it presents disabled people in feminised scenarios. In Chapter 2 I examine the ways in which disability is allied to gender in popular women's magazines where certain bodily specificities and disabilities are associated with female characters. I consider in Chapter 3 the ways in which disabled characters in literature for children are presented as morally inadequate and lacking in self-control, exactly as female characters are depicted in Western culture. In Chapter 4 I address the identity of disability in film as a construction and in some respects as an illusion, as well as the role of disabled characters in the Freudian narrative of psycho-sexual development, and equate this with the role of the female in cultural expressions. In Chapter 5 I examine the cures of the New Testament and the ritual purifications of the Old Testament as a means to eradicate difference from the ideal of the male body. I argue that biblical narrative establishes women and disabled people as a violation of the ideal male body through their categorisation as unclean. In Chapter 6 I analyse pornographic representations of disabled women to investigate the ways in which disabled characters are positioned, like female characters, as the object of the gaze and as such as castrated and fetishised figures. The Conclusion summarises the argument of the thesis and briefly analyses some of the issues that arise around general concerns about the representation of disability.

According to many philosophers and scientists, human sociality is explained by our unique capacity to ‘share’ the mental states of others and to form collective intentional states. Collective intentionality has been widely debated in the past two decades, focusing especially on the issue of its reducibility to individual intentionality and the place of collective intentions in the natural realm. It is not clear, however, to what extent these two issues are related, and what methodologies of investigation are appropriate in each case. In this thesis I set out a theory of the naturalization of collective intentionality that draws a line between naturalizability arguments and theories of collective intentionality naturalized. The former provide reasons for believing in the naturalness of collective intentional states based on our commonsense understanding of them; the latter offer responses to the ontological question about the existence and identity of collective as distinct from individual intentionality. This model is naturalistic because it holds that the only way to establish the place of mental entities in the order of things is through the theory and practice of science. After reviewing naturalizability arguments in philosophy, I consider an influential research program in the cognitive sciences. On the account that I present, the irreducibility of collective intentionality can be derived from a theory of human development in scientific psychology dealing with phenomena of sociality like communication, recently refined by Michael Tomasello.

Impairments in aspects of social cognition have been found in children who have experienced maltreatment; however, the long-term impact of childhood maltreatment on social cognition is less well understood. This study examined areas of social cognition that may be associated with poor psychological, social, and emotional outcomes in adults who have experienced intra-familial childhood maltreatment. In a sample of university students (N = 68), childhood maltreatment was associated with social cognitive impairment in two models of emotional intelligence (EI), trait EI and ability EI, and advanced theory of mind (ToM). Higher frequency and severity of specific subtypes of childhood maltreatment predicted lower trait EI, ability EI, and ToM. In particular, neglect predicted lower ToM and ability EI scores. Psychological abuse alone predicted lower trait EI while physical abuse was not a significant predictor for any of the social-cognitive variables. Further, the data showed maternal vs. paternal maltreatment predicted specific social cognitive outcomes. Understanding the relationship between social cognitive deficits and intra-familial maltreatment may guide clinical and community assessment and treatment approaches, as well as provide information on the pervasive and continuing impact of childhood maltreatment. / February 2017

<p>Making decisions is fundamental to everything we do, yet it can be impaired in various disorders and conditions. While research into the neural basis of decision-making has flourished in recent years, many questions remain about how decisions are instantiated in the brain. Here we explored how primates make abstract decisions and decisions in social contexts, as well as one way to non-invasively modulate the brain circuits underlying decision-making. We used rhesus macaques as our model organism. First we probed numerical decision-making, a form of abstract decision-making. We demonstrated that monkeys are able to compare discrete ratios, choosing an array with a greater ratio of positive to negative stimuli, even when this array does not have a greater absolute number of positive stimuli. Monkeys’ performance in this task adhered to Weber’s law, indicating that monkeys—like humans—treat proportions as analog magnitudes. Next we showed that monkeys’ ordinal decisions are influenced by spatial associations; when trained to select the fourth stimulus from the bottom in a vertical array, they subsequently selected the fourth stimulus from the left—and not from the right—in a horizontal array. In other words, they begin enumerating from one side of space and not the other, mirroring the human tendency to associate numbers with space. These and other studies confirmed that monkeys’ numerical decision-making follows similar patterns to that of humans, making them a good model for investigations of the neurobiological basis of numerical decision-making. </p><p>We sought to develop a system for exploring the neuronal basis of the cognitive and behavioral effects observed following transcranial magnetic stimulation, a relatively new, non-invasive method of brain stimulation that may be used to treat clinical disorders. We completed a set of pilot studies applying offline low-frequency repetitive transcranial magnetic stimulation to the macaque posterior parietal cortex, which has been implicated in numerical processing, while subjects performed a numerical comparison and control color comparison task, and while electrophysiological activity was recorded from the stimulated region of cortex. We found tentative evidence in one paradigm that stimulation did selectively impair performance in the number task, causally implicating the posterior parietal cortex in numerical decisions. In another paradigm, however, we manipulated the subject’s reaching behavior but not her number or color comparison performance. We also found that stimulation produced variable changes in neuronal firing and local field potentials. Together these findings lay the groundwork for detailed investigations into how different parameters of transcranial magnetic stimulation can interact with cortical architecture to produce various cognitive and behavioral changes.</p><p>Finally, we explored how monkeys decide how to behave in competitive social interactions. In a zero-sum computer game in which two monkeys played as a shooter or a goalie during a hockey-like “penalty shot” scenario, we found that shooters developed complex movement trajectories so as to conceal their intentions from the goalies. Additionally, we found that neurons in the dorsolateral and dorsomedial prefrontal cortex played a role in generating this “deceptive” behavior. We conclude that these regions of prefrontal cortex form part of a circuit that guides decisions to make an individual less predictable to an opponent.</p> / Dissertation

<p>Humans are natural politicians. We obsessively collect social information that is both observable (e.g., about third-party relationships) and unobservable (e.g., about others’ psychological states), and we strategically employ that information to manage our cooperative and competitive relationships. To what extent are these abilities unique to our species, and how did they evolve? The present dissertation seeks to contribute to these two questions. To do so, I take a comparative perspective, investigating social decision-making in humans’ closest living relatives, bonobos and chimpanzees. In Chapter 1, I review existing literature on theory of mind—or the ability to understand others’ psychological states—in these species. I also present a theoretical framework to guide further investigation of social cognition in bonobos and chimpanzees based on hypotheses about the proximate and ultimate origins of their species differences. In Chapter 2, I experimentally investigate differences in the prosocial behavior of bonobos and chimpanzees, revealing species-specific prosocial motivations that appear to be less flexible than those exhibited by humans. In Chapter 3, I explore through decision-making experiments bonobos’ ability to evaluate others based on their prosocial or antisocial behavior during third-party interactions. Bonobos do track the interactions of third-parties and evaluate actors based on these interactions. However, they do not exhibit the human preference for those who are prosocial towards others, instead consistently favoring an antisocial individual. The motivation to prefer those who demonstrate a prosocial disposition may be a unique feature of human psychology that contributes to our ultra-cooperative nature. In Chapter 4, I investigate the adaptive value of social cognition in wild primates. I show that the recruitment behavior of wild chimpanzees at Gombe National Park, Tanzania is consistent with the use of third-party knowledge, and that those who appear to use third-party knowledge receive immediate proximate benefits. They escape further aggression from their opponents. These findings directly support the social intelligence hypothesis that social cognition has evolved in response to the demands of competing with one’s own group-mates. Thus, the studies presented here help to better characterize the features of social decision-making that are unique to humans, and how these abilities evolved.</p> / Dissertation
