Social cognitive strengths and difficulties in Down syndrome and Prader-Willi syndrome

We are interested in how children and young people with Down syndrome and Prader-Willi syndrome process and understand social information. We are particularly interested in whether social information processing relates to observable social behaviour skills that are central to navigating day-to-day interactions.

Our research involved tasks and activities that demonstrate a person’s social skills, verbal, and non-verbal abilities. We also used eye-tracking tasks, which involved looking at social information. Parents/carers were asked to fill out some questionnaires and complete an interview over the phone.

We recruited children and young people with Down syndrome (N = 36), and Prader-Willi syndrome (N = 35), aged 4-19-years-old, and would like to say a huge thank you to all these participants and their families. The data has been analysed and we hope to share the results with you soon. It is hoped that this research will lead to improved understanding of the social strengths and difficulties that are characteristic of these syndromes, and possibly associated with co-occurring autism traits.
