In learning multiple paired-associate lists, all with the same stimuli, 5"s may form a new image for each pair or may progressively elaborate the image for a List 1 pair by incorporating each new response item into the image. In the latter, imagery and response-repetition effects are confounded. Analogues of these imagery types were manipulated by imposed pictorial elaboration in 4 paired-associate lists, with college 5s. A control for response repetition was included. The elaboration types were found to be equally superior to their controls, for both serial and free recall, and for both immediate and 1-week delayed testing. Thus, elaboration effects are not lost in long-term retention, serial information is not lost in progressive elaboration, and response repetition and elaboration have separable effects.
