Everely impaired in detecting a sequence by observation,have been able to detect a sequence by performing,and became as effective as TD children in reproducing an observed sequence soon after a task of understanding by undertaking. The understanding pattern of PWS young children was reversed compared with that of WS individuals. Conclusions: The observational learning deficit in PWS people may be rooted,at the very least partially,in their incapacity to understand andor use social details.

PWS individuals are characterized by a downward shift in the distribution of IQ scores and mild to moderate intellectual disability (ID) . Their cognitive profile is characterized by strengths in longterm memory,visual perception,simultaneous processing,reading skill,and visuospatial functions and weaknesses in focus,shortterm memory,sequential processing,executive functions,actionbased visual processing,auditory processing,mathematical skills,language skills,and social cognition . Despite the fact that the behavioral phenotype of PWS people has been characterized with regard to maladaptive behavior and cognitive profile (for a assessment,see ),their social functioning has been only recently examined.
