Perceptual decentering in EMR and nonretarded children.

Perceptual decentering was examined in nonretarded children, EMR children equated for CA, and EMR children equated for MA. Perceptual decentering was measured by the number of part, whole, and integrated responses to a modification of the Picture Integration Test. MA peers (nonretarded and EMR children of equated MA) produced a significantly greater number of decentered (integrated) responses than did EMR children equated with the nonretarded children for CA. The results indicated that perceptual decentering is more fundamentally related to MA than to CA in EMR children.
