APA Dictionary of Psychology

a memory test that involves processing the surface features of a stimulus. Perceptual tests can be used to measure implicit memory, as in word-stem completion in which participants are given sets of introductory letters and asked to form complete words using the first words that come to mind. Such tests can also be used to measure explicit memory, as in the graphemic cued-recall test in which participants are given cues that are similar in physical appearance to the target item but differ in meaning (e.g., fickle as a cue for freckle). Compare conceptual test.
