Long-Term Perceptual Memory in Educable and Trainable Retardates and Children with Learning Disabilities. Final Report.
Raskin, Larry M.
Three short studies were conducted on long-term effects of visual perception training on perceptual memory, involving the visual illusion of apparent movement, in educable and trainable mentally retarded children (EMR and TMR) and in learning disabled children (LD). Variables were lengths of training session and retention interval. Tables presented information on subjects and experimental conditions for the three studies, number of children reporting arrow-to-square movement in training session, and number of children reporting movement in arrow-to-arrow series in test session. Test results of the first study of 36 EMRs and 24 normal children indicated that EMRs must receive more perceptual training experience than normal children of the same mental age to establish enduring perceptual memory. Results of the second study with 80 LDs suggested that LDs showed a deficit in long-term perceptual memory similar to that found for EMR and TMR populations, indicating a possible common learning problem, independent of intellectual functioning level. Test results of the third study with 24 TMRs indicated a trend toward reduction in effects of dissimilar-form training over 24 hours. (CB)
