Subjects who scored high or low on a measure of visual imagery ability completed three recognition tests for a series of pictures they had viewed 48 hours earlier.
Abstract
The tests assessed recognition of previously shown objects, queried either by identity cues (same picture) or by variant cues (different picture of the same object). The subjects were twelve female undergraduate volunteers. The discrimination index, d prime, was greater for High Imagery subjects and was modestly increased across tests for variant cues, but not for identity cues. High Imagery subjects also employed different decision criteria (B) with the two sets of cues, but the Low Imagery subjects did not. These strategic response biases may reflect imagery-related differences in the quality or utility of memory trace in recognition. 4 figures, 8 references. (Author abstract modified)
