The current thesis investigated Theory of Mind and perspective-taking ability amongst adults with intellectual disabilities. The initial article provided a literature review of 52 studies focussing on this area. The review considered the extent to which people with intellectual disabilities experience difficulties in Theory ofMind that are similar to those difficulties commonly attributed to persons. with Autistic Spectrum Disorder. The review also included an evaluation of other key abilities that have been highlighted in the Theory ofMind literature. Throughout the review, an· emphasis was placed on the appropriateness of cognitive models for understanding, assessing and enhancing Theory ofMind. Overall, it was suggested that people with intellectual disabilities exhibit a range of- - difficulties in this area and that the development of an alternative theoretical approach may therefore be necessary. Within this context the main research study reported in the current thesis aimed to furth~r investigate the perspective-taking abilities of 24 adults with intellectual disabilities. In addition to using a traditional test of perspective-taking, the study utilised a recently developed protocol based on Relational Frame Theory, a functional contextualist account of language. All participants were able to respond to items on the protocol suggesting the appropriateness of methodologies based on this approach for the future. In addition, differences were observed between participants scores on each level of difficulty and type ofquestion used, suggesting these measured functionally distinct classes of behaviour. Associations were also evident between additional measures of general, verbal and non-verbal ability and certain items on the protocol. The final section of the thesis provided a critical review of the main research paper, extending upon discussion of findings and their implications for future research and clinical practice. This included details of a presentation evening held for participants and their carers following completion of the study. /
