4. The role of Motivation in autism and ADHD

Goal: To determine if cognitive control in children with autism and ADHD can be improved.

Results: We concluded that children with ADHD motivation had a general effect on performance and was not solely related to cognitive control abilities. In contrast, this effect was not obtained in children with autism. Motivation might play a larger role in ADHD as compared to autism. In one of these studies we also showed that the Sensitivity to Punishment and Sensitivity to Reward Questionnaire for children (SPSRQ-C/BIS-BAS), is of value to quickly and reliably assess a child’s sensitivity to reinforcement. We ran a few follow up studies, but we are still in the process of disentangling the outcome of these studies. Moreover, we are using these experimental paradigms and the SPSRQ-C to determine whether reward sensitivity is a predictor for treatment outcome.
