Research & Scholarship
University research group memberships
I am currently a member of the Institute for Research in Citizenship and Applied Human Sciences and the Centre for Applied Psychological Research.
Over the years I have focused on: (a) Reduction of challenging behaviour in people with learning disability in particular anger and aggression. This has mainly involved mata-analysing the published literature. In addition, a number of single case studies demonstrating effectiveness of assessment and treatment methods have been published. (b) The measurement of IQ in people with learning disabilities. Several theoretical papers on the limitations of IQ testing with people with learning disabilities have been produced. Currently a meta-analysis of reliability of intellectual assessments is in preparation and an empirical analysis of IQ assessments done in the Learning Disability Clinical Psychology department has just been submitted for publication. (c) The nature, definition and naming of Learning Disability. In addition, papers have been produced on evidence-based practice, the prevalence of learning disabilities, and the prevalence and nature of mental illness. Ethical approval has been obtained to do further work in the assessment of challenging behaviour and on the effectiveness of intellectual assessments.
I have an additional research interest which is "The assessment of low intellectual ability".
