Serial Recognition Memory by Retardates of Half or Whole Faces in Two Orientations

Abstract

Sequences of whole faces and half faces, either upright or inverted, were shown to 24 educable retardates in a paced recognition memory procedure. Inverted faces were harder to recognize than upright faces and half faces were harder to recognize than whole faces. An interaction trend showed that the half-whole effect was more marked for the upright faces. The results, combined with earlier data, suggest that some factor in the upright whole face is crucial to the half-whole difference found with retarded Ss.
