Abstract

This present study evaluated the use of conditional discrimination training and a self-control procedure to increase task compliance, task preference and self-control in three participants. All three participants were previously diagnosed with autism and attention-deficit/hyperactivity disorder. Using a multiple baseline design, participants were first exposed to a preference assessment, a naturalistic baseline and a choice baseline. A relational responding task was then introduced, which attempted to alter the functions of contextual cues associated with `more than' and `less than'. A choice baseline was re-administered to support the transformation of functions and the larger, delayed reinforcer was thinned within a second choice baseline. A final preference assessment was completed that showed an increase in preference of a previously least-preferred task. Results of the procedure showed an increase of self-control, task compliance and task preference. Suggestions for future research and limitations of the study are also discussed.
