Reports of a relatively high prevalence of absolute pitch (AP) in autistic disorder suggest that AP is associated with some of the distinctive cognitive and social characteristics seen in autism spectrum disorders. Accordingly we examined cognition, personality, social behavior, and language in 13 musicians with strictly defined AP (APS) and 33 musician controls (MC) without AP using standardized interviews and tests previously applied to identify the broad autism phenotype seen in the relatives of autistic probands. These included the Pragmatic Rating Scale (PRS) (social aspects of language) the Personality Assessment Schedule (PAS) (rigidity, aloofness, anxiety/worry, hypersensitivity), and WAIS performance subtests (PIQ). On the basis of their behavior in the interviews, subjects were classified as socially eccentric, somewhat eccentric, or not eccentric. Forty-six percent of the APS, but only 15% of the MC, were classified as socially eccentric (p < .03). APS but not MC showed higher scores on block design than on the other PIQ tests (p < .06), a PIQ pattern seen in autism spectrum disorders. Although APS and MC did not differ significantly on other measures it is of note that APS mean scores on the PRS and PAS (5.69, 4.92) were almost twice as high as those for the MC (3.03, 2.45). Thus, musicians with AP show some of the personality, language, and cognitive features associated with autism. Piecemeal information processing, of which AP is an extreme and rare example, is characteristic of autism and may be associated as well with subclinical variants in language and behavior. We speculate that the gene or genes that underlie AP may be among the genes that contribute to autism.

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.
