    Abstract

    This study was designed to investigate the abilities of individuals with mental retardation to recognize and match emotional facial expressions from a series of photographs depicting various facial expressions. There were four groups of participants according to their place of residence (community or institution) and their intelligence level (mild or moderate). Each individual participated in two tasks: (1) recognizing a facial expression from an array of three pictures presented, and (2) matching a facial expression from one picture with a picture depicting a similar emotion from an array of three pictures. All information was presented to the participants in the native language, Hebrew. The six facial expressions used for the study included happiness, sadness, fear, anger, surprise, and disgust. The ability to recognize and match facial expressions was significantly higher for individuals with mild than moderate mental retardation. There was no significant difference for place of residence. Happiness was the easiest feeling to recognize and match for all groups. Fear and anger were the most difficult to recognize, while sadness and anger were most difficult to match.
