Pretesting boosts recognition, but not cued recall, of targets from unrelated word pairs.

Abstract

Attempting to retrieve the answer to a question on an initial test can improve memory for that answer on a subsequent test, relative to an equivalent study period. Such retrieval attempts can be beneficial even when they are unsuccessful, although this benefit is usually only seen with related word pairs. Three experiments examined the effects of pretesting for both related (e.g., pond-frog) and unrelated (e.g., pillow-leaf) word pairs on cued recall and target recognition. Pretesting improved subsequent cued recall performance for related but not for unrelated word pairs, relative to simply studying the word pairs. Tests of target recognition, by contrast, revealed benefits of pretesting for memory of targets from both related and unrelated word pairs. These data challenge popular theories that suggest that the pretesting effect depends on partial activation of the target during the pretesting phase.
