Incidental learning, noun imagery-concreteness and direction of associations in paired-associate learning.

Examined the effect of imagery-concreteness pairs in incidental learning. In Exp. I with 96 undergraduates, intentional learning was superior to incidental learning. Recall of concrete-concrete noun pairs was significantly better than recall of all other pairs, while concrete-abstract and abstract-concrete nouns did not differ from each other but did differ from abstract-abstract recall. In Exp. II with 64 Ss, instructions to use imagery during the orientation task resulted in similar performance for incidental and intentional learning Ss. Concreteness yielded a greater effect on the stimulus side than on the response side of pairs, particularly for stimulus-response recall. Associative directionality had no reliable effects in either experiment. Results are discussed in terms of A. Paivio's conceptual peg hypothesis and 2-process theory of verbal and imaginal memory.
