Enactment and retrieval

The enactment effect is one of a number of effects (e.g., bizarreness, generation, perceptual interference) that have been treated in common theoretical frameworks, most of them focusing on encoding processes. Recent results from McDaniel, Dornburg, and Guynn (2005) call into question whether bizarreness and, by association, related phenomena such as enactment are better conceptualized as arising due to retrieval processes. Four experiments investigated the degree to which retrieval processes are responsible for enhanced memory for enacted phrases. Participants were presented with two pure study lists and later recalled the lists separately (inducing pure retrieval sets) or recalled the lists together in a single test (inducing a combined or mixed retrieval set). Across all four experiments, the combined recall condition consistently failed to enhance the size of the enactment effect. The results provide no support for the retrieval account but are generally consistent with encoding accounts.
