AN INVESTIGATION OF CROSS-MODALITY EFFECTS IN IMPLICIT AND EXPLICIT MEMORY

Three experiments are reported which investigate the effects of study/test compatibility on implicit and explicit memory performance. In the first experiment subjects either named each visually presented target item, or generated each item from a close semantic associate. They were then given either a free recall test or a visual word-stem completion task. A generation effect was evident in the free recall data (generated items were better recalled than named items) and this pattern was reversed for word-stem completion. In the second experiment subjects again named or generated items and were then given an auditory word-stem completion task. Under these conditions, cross-modal priming was found both for named and for generated items, but the reverse generation effect, which was evident in Experiment 1 with word-stem completion, was eliminated. In the final experiment, subjects were asked to name the targets, read them silently, or read them under conditions of articulatory suppression, and were then given an auditory stem completion task. Significant cross-modal priming was observed under all three conditions. The strongest priming was found in the naming condition and the weakest in the suppression condition. The results are interpreted within the transfer appropriate processing framework.
