This study compared implicit and explicit memory in mentally retarded adults versus university students. Subjects were shown 20 increasingly complete pictures until they were correctly identified. After two retention intervals, 5 minutes and 1 week, half of 20 pictures and 10 new pictures were presented for indetification using the same procedure. After idetifying each picture, subjects were asked whether or not they had seen it before. Perceptual priming effects on picture fragment completing (implicit memory) and recognition rates (exlicit memory) were compared. Recognition rates differed between the two groups irrespective of retetion intervals. Both groups showed significant priming effects. In spite of their poor performance at recognition, the priming effect in the retarded group did not differ from that of the university students. A group X interval interaction was foud. These results suggest that mentally retarded adults can remember past events as well as college students so far as information was processed implicity. The above results, therefore, can demonstrate that performance on implicit memory does not improve with intelligence.
