A novelty preference method was used to examine memory processes in profoundly, severely, and moderately retarded persons. After viewing a photograph of a face for 30 seconds, subjects were shown the study face and a new one after intervals ranging up to 3 minutes. Data were obtained from 30 of 56 subjects with this method. Of the 30 subjects, 20 showed significant preference for looking at the new face in the test. Recognition memory as indexed by novel looking declined over the retention interval. Memory was stronger but decayed more rapidly for higher memorable (distinctive) faces. With refinement, the novelty preference method holds promise for the study of cognitive processes in nonverbal persons. But, since memory is being inferred from response preferences which reflect an induced motivational state, satiation, the relationship between this state and memory must be established. |
