The experiments presented in this study tried to validate and clarify the notion of distinctiveness and the assumptions on which it is based, particularly as it relates to prediction of the serial-position effect. (Author/RK)

These experiments demonstrated that it is possible to produce induced amnesia using a loud sound as the critical item when all other items are presented at normal conversational levels. (Author/RK)

Subjects asked to recall the 20 items and (not necessarily in) their order on a list took 34 percent fewer trials to learn the list to three perfect trials than did subjects who were asked just to recall the items. (Editor)

Cronbach, in 1957, supported the unification of two disciplines of scientific psychology--the correlational and experimental approaches. The remaining papers in this journal issue--which served as the basis for a 1978 American Educational Research Association Symposium--address this issue. (Author/RD)

The tasks with item and position probes seem similar. Given an item probe, a subject must recall its position in the spatial array; given a position probe, the item in that position in the array. Analysis of correct responses and latencies showed that item and position probes yielded different results. (Editor/RK)

Free-recall (FR) instructions produce substantially different patterns of retention than serial recall (SR) instructions. In the present experiments an effort was made to determine to what extent two factors contribute to the dissimilarities between FR and SR. (Author/RK)
