Time-based prospective memory (TBPM) is one's ability to remember to do something at a certain time in the future (Graf & Grondin, 2006). Of interest is whether congruency or incongruency between an ongoing task and a TBPM task influences TBPM performance. The present study examined this notion by varying the conditions in which participants performed the ongoing task in relation to the TBPM task. Sixty-five college students were randomly assigned to a congruent or incongruent condition, wherein they performed an ongoing task behaviorally or verbally in combination with a behavioral or verbal TBPM task (four conditions total). No significant main effects were found for behavioral responses over verbal responses on the ongoing and TBPM tasks. Additionally, no interaction effect was found between the congruent and incongruent condition types. Future research should focus on varying the task parameters surrounding making a TBPM response.
