Study-test awareness can enhance priming on an implicit memory task: evidence from a word completion task.

The role of study-test awareness in implicit memory tasks has been an open question for some time. This study investigated the possibility that study-test awareness may enhance priming on an implicit memory task. In three experiments, subjects studied words under levels of processing conditions (nonsemantic vs. semantic) and then received a word stem completion priming task. The results of all three experiments showed that study-test awareness had no effect on priming for nonsemantic study but it did on semantic study, significantly enhancing priming for that study condition. The results are interpreted according to an involuntary aware memory framework.
