The aims of this study were twofold and integrated. The first was to explore whether Hans Asperger’s expression ‘autistic intelligence’ was a valid and possibly helpful concept to educators. The second was to discover whether this theorised cognitive style could be accommodated within an inclusive education framework. Four students on the autism spectrum, in mainstream schools, their parents and their teachers were interviewed in a case-study approach, to analyse their beliefs and understandings about autism. Data analysis showed that parents and students in particular believed autism to involve a recognisable cognitive style. It tended, they said, to have sensory elements which impacted upon engagement and learning, and appeared to give rise to some social difficulties. These in turn were thought to impact upon the emotional wellbeing of students on the autism spectrum. Significant bullying and exclusion of these students was reported. They recognised their ‘difference’ from their peers and attempted to negotiate that difference. However, teachers tended to reject the concept of ‘labelling’ these students. These findings in part reflect developing current theoretical and cognitive neuroscience consensus supporting a theorised Local Processing Bias as perhaps being a key element in defining core characteristics of autism. Additionally the research showed that the inclusive framework was perceived to be failing these students in many ways. In particular, the difficulties in obtaining educational help and support were believed, by students and their parents, to be obstructive. Another area of concern was the use of teaching assistants as the main educational intervention offered. The inclusive framework, according to these stakeholders, appears to have little recognition of or accommodation for what might be called autistic intelligence. Yet this might possibly be accomplished by making some environmental adaptations. The concept of autistic intelligence, with its theorised perceptual bias, might be useful in considering the nature of any adaptations.

This thesis investigates the role of group processes in children’s responses to bullying from the perspective of social identity and group-based emotion theories. It starts by reviewing research on group-based emotions in adults’ intergroup relations, and on social identity processes in children. It is argued that studying children’s group-based emotions might enhance our understanding of group-level bullying. Initial results suggested that group-based emotions related to supporting and resisting cyberbullying depend upon children’s social identity, and that group-based emotions lead to specific action tendencies (Study 1). Wider group norms were investigated in Studies 2 and 3. In Study 2 the prevailing normative context shaped responses to bullying, while in Study 3 peer group norms had a greater influence than school norms on children’s responses to bullying. The way that children manage their social identity in response to bullying was examined in Study 4. How strongly perpetrator’s group members identified with that group was determined by initial ingroup identification and the perpetrator’s group norm. How group norms shape interpretations of bullying when it is ostensibly negative (Study 5a) or ostensibly positive (Study 5b) was studied next. It was found that certain group-based emotional responses and action tendencies were inhibited when the bullying was misaligned with group norms. Group processes in school bullying incidents were examined in Study 6. A qualitative analysis of teachers’ accounts of bullying revealed that although bullying is responded to primarily at the group level, such responses do not directly address group processes. In Chapter 8 I draw the thesis together by highlighting the role that group processes play in children’s responses to bullying. Implications for antibullying work are discussed. It is concluded that successful intervention rests on awareness of the group processes (a) that lead children to become involved in bullying, and (b) by which bullying may be resisted.

Psychological models of psychotic experiences suggest that social adversity (e.g., difficult family relationships, bullying) and anomalous percepts play an important role in the development of paranoid thinking, while intrusive cognitions and problems in reality discrimination play an important role in the development of auditory hallucinations (AH). The studies reported in this thesis examined a number of research questions relevant to these models, by investigating psychotic experiences in non-clinical populations (typically referred to as psychotic-like experiences, or PLEs). In Study 1 it was shown that the association between poor parental bonding and PLEs is mediated by individual differences in exposure to bullying and levels of negative affect. In Study 2 it was shown that associations between insecure attachment styles and paranoid thinking are mediated by individual differences in loneliness. In Study 3 it was shown that the association between experiencing anomalous percepts and paranoid thinking is moderated by individual differences in attachment anxiety. In Study 4 it was shown that the association between experiencing intrusive thoughts and AH-proneness is moderated by individual differences in reality discrimination skills. Finally, in Study 5 it was shown that a person’s reality discrimination abilities can be weakened through the induction of a negative mood. The studies included in this thesis, therefore, show how a variety of social, emotional, and cognitive factors interact with each other to foster or preclude the development of PLEs in ways that extend current psychological models of AH and paranoid thinking.

Bullying is a widespread public health problem. While its prevalence, key correlates and major health outcomes have been well researched, important gaps or controversies remain. In particular, the association between bullying and both socioeconomic status and ethnicity remains unclear. Furthermore, other areas are under-researched, such as sibling aggression and its relationship to peer bullying. Finally, while there is evidence of the adverse effects of bullying on mental health, there is still uncertainty whether any experience of being bullied, or only sustained, chronic victimisation, will lead to adverse consequences. Do those who escape bullying fare better? This thesis comprises five studies. Study 1, a meta-analysis, explored the relationship between bullying and socioeconomic status, finding victims and bully-victims, but not bullies, more often came from low socioeconomic backgrounds. Study 2 examined sibling aggression, identifying a strong homotypic association with roles taken in school bullying. Study 3 explored ethnic differences in bullying, finding ethnic minority children were not more likely to be victims, but in some cases were more often bullies. Study 4 identified individual, social and sociodemographic correlates of school bullying. Distinct profiles were observed for each bullying role. Finally, Study 5 examined the timing of bullying in relation to individual and social outcomes. Stable and concurrent victimisation was associated with more negative outcomes, while escaping bullying reduced the adverse consequences. The findings are considered in relation to ecological systems theory. Distant environmental factors, such as socioeconomic status, were only weakly associated with school bullying, while more immediate socio-ecological influences, including sibling relationships and individual characteristics, predicted victim, bully and bullyvictim roles. Further research should focus on the association with sibling aggression, and identify characteristics which can explain why some children escape being bullying, thereby limiting the adverse consequences. The findings have implications for interventions, which should take account of children’s home environments.
