Training task switching to decrease temper outbursts in people with PWS

Temper outbursts are commonly shown by people with Prader-Willi syndrome (PWS) and can cause great problems for people with the syndrome, their family members and caregivers. One common reason for temper outbursts is that people with PWS find changes to routines or to plans very difficult. This difficulty with change is linked to impairment in a particular cognitive function called task switching.

The objective of this project is to develop a computer software training program to improve task switching. The program will be sensitive to the individual needs of people with PWS. Collaboration between Computer Engineers and Psychologists will ensure that the skills that participants learn are not limited to the training environment but instead transfer to general improvements in task switching.

Six children with PWS and their parents/caregivers will participate. Children will be given access to selected computer games over one month in order to compile a set of computer game components that children find highly motivating. Following this, on three occasions children will take part in several sessions of engaging with different draft versions of the training. Children’s behaviour will be observed, heart rate, skin conductance facial muscular activity, and child- / parent- reports will be recorded, and children’s performance on the training activities will be measured. These measurements will allow a version of the training to be compiled that is optimal for producing improvements in task switching. Children will then participate in the training program, and a preferred computer game (a placebo), each over five weeks. Improvements in task switching will be measured using carefully designed cognitive tests and an informant report questionnaire.

Evidence from this study that the training can produce improvements in task switching is critical to secure funding to further develop cognitive training as an effective intervention for temper outbursts in people with PWS.
