The effects of levels-of-processing and organization on conceptual implicit memory in the category exemplar production test

The distinction between item-specific and relational information (Hunt & Einstein, 1981) may be relevant to accounts of conceptual priming in the category exemplar production task. In three experiments, the implications of this hypothesis were tested by examining the effects of organization and levels-of-processing (LOP) on this implicit test. Consistent with the hypothesis, the effects of LOP were greater when study lists were organized by category than when they were presented randomly. Furthermore, when subjects claiming test awareness or intentional retrieval were excluded from the analysis, the LOP effect was reduced land, in fact, eliminated) in the random list condition but remained robust in the categorized condition. Finally, the experimental design of the LOP manipulation (i.e., mixed-list within, blocked-list within, or between subjects) did not moderate the effects of LOP on this priming task.
