記憶過程における選択的リハーサルと情報の精緻化について

The purpose of the present study was to investigate the effect of elaborative rehearsal and the degree of differentiation between to-be-remembered (R) and to-be-forgotten (F) items in selective memory. The item-by-item cueing procedure was used in presenting subject with 36-item list composed of four categories. R and F items for Category group belonged to different semantic categories, but to same categories for Noncategory group. Immediate and final free recall of R items, which were better for Category group than for Noncategory group, increased as a function of interval-length for both groups. As for F items, however, more intrusion errors (immediate recall) and more amount of recall (final recall) were found for Noncategory group. These results suggested that elaborative rehearsal and retrieval effort were important factors to facilitate memory performance.
