The error negativity (Ne/ERN) is a component of the event-related brain potential, and its amplitude is believed to reflect the attentional resources allocated to error monitoring. The purpose of the present study was to examine Ne/ERN amplitude changes using a dual-task paradigm to see if they were consistent with the multiple resource model. My dual task paradigm employed the Eriksen flanker task as the primary task and the Sternberg memory search task as the secondary task. I manipulated the task difficulty of the secondary task by changing the stimulus-response mapping. The results indicated that the Ne/ERN amplitude decreased in the primary task as the secondary task became more difficult. As such, the multiple resource model did not account for the allocation of attentional resources associated with error monitoring.
