| Cognitive control describes our ability to flexibly adapt information processing and behavior in order to meet task demands. One method of examining cognitive control is to experimentally introduce conflict in order to examine how control is recruited and implemented. While research has typically focused on the idea that conflict occurs at a response level (Botvinick, Braver, Barch, Carter, & Cohen, 2001), fewer investigations have examined conflict that occurs at a representational level (Milham et al., 2001). Using a color-word Stroop task and event-related potential technique, the present study examined the relationship between behavioral (reaction time) and electrophysiological (N450 component and conflict slow potential component) indices of cognitive control. Although we found both behavioral and electrophysiological evidence of conflict adaptation, magnitude of these indices do not correlate. The current study provided insight into how these indices of cognitive control are represented under conditions that separate representational conflict from response conflict. |
