The revelation effect is a phenomenon wherein performing a cognitive task before a recognition judgment induces “old” responses. One of the theories for the occurrence mechanism of the revelation effect is the criterion shift account (Niewiadomski & Hockley, 2001). This account explains that because working memory is occupied when people solve a cognitive task, they adopt a more liberal criterion for recognition judgments immediately after a cognitive task than those with no preceding cognitive task. However, no studies of the revelation effect in which manipulation of working memory was intended have been conducted. We examined whether working memory load and capacity are related to the revelation effect. The results showed that neither the occurrence of the revelation effect nor its degree was affected by working memory load or capacity. As the results suggest working memory is not related to the revelation effect, a partially or entirely alternative account that can explain the revelation effect is needed.
