Ten moderately retarded, well-practiced children served as Ss in a repeated measures design. The task was the recognition of pictures using a probe procedure. Accuracy decreased as a function of number of pictures (1, 5, 9, or 15) that were present and latency of response increased. Correlational analyses showed high reliabilities and high intercorrelations among the accuracy scores and among
