Abstract

The Stroop effect is composed of interference and facilitation effects. The facilitation is less stable and thus many times is referred to as a " fragile effect" Here we suggest the facilitation effect is highly vulnerable to individual differences in control over the task conflict (between relevant color naming and irrelevant word reading in the Stroop task). We replicated previous findings of a significant correlation between stop-signal reaction time (SSRT) and Stroop interference, and also found a significant correlation between SSRT and the Stroop facilitation effect-participants with low inhibitory control (i.e., long SSRT) had no facilitation effect or even a reversed one. These results shed new light on the " fragile" facilitation effect and highlight the necessity of awareness of task conflict, especially in the Stroop task.
