The PWS chromosome 15q11-13 maternal uniparental disomy (mUPD) subtype displays greater ASD symptoms than the paternal deletion (DEL) subtype.

Visual perception may be a developmental prerequisite to some types of social understanding. The ability to perceive social information given visual motion appears to develop early. However, children with autism have profound deficits in social cognitive function and may fail to see social motion in the same way that typically developing children…

A Discussion of "Nadia": A Case Study of Extraordinary Drawing Ability in an Autistic Child. Technical Report No. 9.
Pariser, David A. – 1979
The case study of Nadia, an autistic child, documents the phenomenally accurate drawings she made. Nadia's precocious drawing capacity raises questions about the drawing hypothesis adhered to by F. Goodenough and D. B. Harris and Gestalt theories of perception and representation. The argument is made that Nadia drew realistically because she…
