The effects of a levels-of-processing manipulation on false recall
The present study attempted to determine the effect of a levels-of-processing manipulation on the incidence of false recall. In Experiment 1, participants engaged in either a vowel counting task or a concrete/abstract rating task; in Experiment 2, participants engaged in either a vowel counting task or a category sorting task. Results of both experiments demonstrated that participants who engaged in a deeper level of processing (i.e., concrete/abstract ratings or category sorting) recalled significantly more list items and critical lures. The present findings thus lend support to theories that attribute false memories to activation-based factors.
