Developmental changes in facial expression recognition in Japanese school-age children.

Purpose: Facial expressions hold abundant information and play a central part in communication. In daily life, we must construct amicable interpersonal relationships by communicating through verbal and nonverbal behaviors. While school-age is a period of rapid social growth, few studies exist that study developmental changes in facial expression recognition during this age.

[A study of cognitive and behavioral development in pre-school and school children with high functioning pervasive developmental disorder].

It has been reported that school-aged children with high functioning pervasive developmental disorder (HFPDD) have numerous difficulties in their school class. We used three psychological tests to investigate whether there is a relationship between intelligence and cognitive, behavioral development in children with HFPDD. The three tests used were an intelligence test (WIPPSI, WISC-lll), the P-F (Picture Frustration) study, and behavioral assessment by their parents.
