Abstract
Cognitive performance on working memory tasks differs with motivation, however with little direct study on the interaction between reward motivation and working memory tasks in humans. Working memory tasks utilize cognitive executive functions such as inhibition, updating, and shifting. In this experiment, we studied the relationship between external monetary motivation and the cognitive strategies used to complete a series of 3 updating span working memory tasks. Participants used either an active updating strategy (maintaining and updating information in working memory) or a passive receiving strategy (recall of information at end of trial). The 3 updating span tasks included a letter-memory, a keep-track, and a tone-monitoring task. From 23 participants, we discovered significant differences caused by self-reported active strategy usage for the Tone-Monitoring task, and for a model including the interaction between motivation and reported strategy usage for the Letter-Memory task. This study shows that performance-contingent rewards affect WM updating, and open the potential for further research into the nature of motivation and WM components.
