Children with Prader–Willi syndrome (PWS) are at risk for autism spectrum disorder (ASD), including pervasive social deficits. While play impairments in ASD are well documented, play abilities in PWS have not been evaluated. Fourteen children with PWS and ten children with ASD were administered the Autism Diagnostic Observation Schedule (ADOS) (Lord et al. in Autism Diagnostic Observation Schedule manual. Western Psychological Services, Los Angeles, 2006) as part of a larger project. A modified Affect in Play Scale (APS; Russ in Play in child development and psychotherapy: toward empirically supported practice. Lawrence Erlbaum Associates Publishers, Mahwah, 2004; Pretend play in childhood: foundation of adult creativity. APA Books, Washington, 2014) was used to score ADOS play activities. Results indicate both groups scored below normative data on measures of imagination, organization, and affective expression during individual play. In addition, the inclusion of a play partner in both groups increased all scaled scores on the APS. These findings suggest children with PWS show impaired pretend play abilities similar to ASD. Further research is warranted and should focus on constructing and validating programs aimed at improving symbolic and functional play abilities within these populations.

There is growing recognition that children have less time to engage in play, and, concurrently, recent evidence suggests a decrease in divergent thinking ability in young children. This study investigated changes in pretend play ability during a 23-year period. The same standardized measure of pretend play, the Affect in Play Scale (APS; Russ, 1993 Russ , S. W. ( 1993 ). Affect in creativity: The role of affect and play in the creative process . Hillsdale , NJ : Lawrence Erlbaum Associates . [Google Scholar] ; 2004 Russ , S. W. ( 2004 ). Play in child development and psychotherapy: Toward empirically supported practice . Mahwah , NJ : Lawrence Erlbaum Associates Publishers . [Google Scholar] ), was the measure of pretend play in all studies. This puppet play task is videotaped and scored from the tapes. Fourteen studies of children from 6 to 10 years of age in school-based samples from 1985–2008 were included in the analyses. A cross-temporal meta-analysis examined correlations between weighted mean scores and year of data collection. Main findings were that imagination in play and comfort with play significantly increased over time. There was no evidence of change in organization of the story or in overall expression of affect in play. When one outlier was removed, there was a significant decrease in negative affect expression in play. Even though children have less time to play, cognitive processes that occur in play are continuing to develop. Whether these pretend abilities are being transferred to creative production is a key question for future investigation.
