Four presentations in two recall conditions (immediate and one-week delay) were used to investigate the combined effects of imagery and semantic organizational strategies on the free recall of 80 college undergraduates. Both imaginal and semantic organization were comparably manipulated presenting each response noun simultaneously with an imagery pegword and a semantic category label. The to-be-remembered (TBR) nouns were given either in a consecutive, uninterrupted (massed) order or an interspaced (distributed) order with both cue-terms (imaginal pegword and semantic category label). The massed ordering was significant for semantics, but not for imagery. Interaction effects were tentatively concluded to be the result of differences in the organizational properties of short-term and long-term memory. Imagery was found to be a little-used organizational strategy by the students. Semantic categories, however, were shown to be a powerful strategy for the organization and retrieval of the TBR nouns in both short-term and long-term memory. (Author)
