A series of studies indicated that performance on serial recognition memory tasks was relatively constant over a wide range of age and IQ, and except for response biases and forgetting rate, recognition memory processes of normal and retarded children appeared to be identical with those of adults. (Author/DR)

Explores the effect of stimulus familiarity on the spatial primacy performance of normal and retarded children. Assumes that serial recall tasks reflect spatial memory rather than verbal rehearsal. (BD)

Two studies are reported. The first is based on Piaget's assertion that the child's representation of his world is dependent on the level of cognitive development at which he is currently functioning. Forty-eight normals and 48 retardates were given a visual memory task. They were asked to recall a configural presentation in a number of ways,…
