Evaluated was the continuous recognition memory of 20 undergraduate students and 20 retarded adults. Available from: Ablex Publishing Corporation, 355 Chestnut Street, Norwood, New Jersey 07648. (CL)

A reevaluation of a number of experiments suggests that normal and retarded persons differ on short-term memory tasks from the time of initial stimulus exposure. The hypothesis that memory differences are due to differential encoding as a result of more adequate rehearsal by the normal subjects is unacceptable. (Author/BW)

Individual differences in memory were examined from the levels of processing perspective. The hypothesis that retarded persons process at a more superficial level was not supported. A "Spread of encoding" deficit in retarded persons is favored to explain the recall differences obtained in this experiment. (Author/LMO)

Ninety-six mildly mentally retarded persons and 96 nonretarded college students estimated the frequency of occurrence of words and pictures in a study test paradigm. Frequency estimates were equal for words, but the nonretarded subjects were superior in accuracy on pictorial items. This finding points to an encoding deficiency attributed to…

A novelty preference method was used to examine memory processes in retarded persons. Recognition memory as indexed by novel looking declined over the retention interval. Since memory is being inferred from response preferences which reflect an induced motivational state, satiation, the relationship between this state and memory must be…

Retarded and nonretarded persons were compared on a task designed to preclude the use of cognitive strategies. Results suggest the possible importance of automatic processing deficiencies and invite a reconsideration of the idea that the relationship between intelligence and memory is due entirely to effortful processes.
