Reports on two experiments conducted to test the hypothesis that the spacing effect in free recall results from greater semantic-feature variability across distributed repetitions than massed repetition. (AM)

Reports on research on the effect of various encoding and retrieval conditions on sentence recall. (AM)

Presents a series of four experiements designed to test the view that the process where a spoken suffix impairs retention of a sequence's last item has a different basis from that producing impairment of the retention of an earlier item. (AM)

Four experiments examined priming between newly learned paired associates through two procedures, lexical decision and item recognition. Results argue against a functional separation of the semantic and episodic memory systems. (Author/AM)

Reports on experiments examining the semantic organization of concrete nouns and verbs and its development in childhood. Differences in semantic organization are said to be a clue to age-related changes in performance with verbs. (AM)

Reviews recent experimental and theoretical analyses of the relationship between level of processing and retention, and reports on two studies which tested predictions about the effects of orienting activities on retention. (AM)

Reports on research showing that when an event, or a problem, is repeated, the processing of that event is not necessarily repeated. Instead, sometimes the solution is remembered, and this is shown to influence subsequent retention, as well as such tasks as word perception. (AM)

Reports on a study that sought to test theories which predict that spacing between two items to be learned improves the probability of remembering at least one of the items. (AM)
