Challenging behaviours and severe learning disabilities: Recent developments in behavioural analysis and intervention

Recent years have witnessed the gradual emergence of a technology of nonaversive behavioural support for people with severe learning disabilities and seriously challenging behaviours. Three key aspects of these developments are reviewed, including: the functional perspective to analysis and intervention; the incorporation of the analysis and modification of setting events into behavioural practice; and the use of experimental techniques to conduct functional analyses of the contextual control of challenging behaviours. Attention is drawn to the practical implications and limitations of these developments.
