Motivated to retrieve: how often are you willing to go back to the well when the well is dry?

Despite the necessity of the decision to terminate memory search in many real-world memory tasks, little experimental work has investigated the underlying processes. In this study, the authors investigated termination decisions in free recall by providing participants an open-ended retrieval interval and requiring them to press a stop button when they had finished retrieving. Three variables important to assessing one's willingness to search memory were examined: (a) the time spent searching memory after the last successful retrieval before choosing to quit (the exit latency); (b) task difficulty; and (c) individual differences in motivation, as measured by Webster and Kruglanski's (1994) Need for Closure Scale. A strong negative correlation was found between individual differences in motivation and participants' exit latencies. This negative correlation was present only when the retrieval task started out as relatively difficult. PsycINFO Database Record (c) 2007 APA, all rights reserved.
