He has served on a wide range of regional, national and international bodies, and has supervised a substantial number of PhD students to completion.
John’s core research interests are in language and cognitive development in typically developing children and in a number of special groups, including deaf children and children with Down syndrome and he has published extensively in these areas.
Other recent work has included studies of hemispheric lateralisation in deaf and hearing users of signed and spoken language, evaluation of a multi-professional intervention package for children experiencing difficulties at school, assessing the benefits of a physical exercise programme for children with learning disabilities, evaluating children’s experience of the Common Assessment Framework and the assessment and impact of dementia in people with Down syndrome.
