The negative compatibility effect (NCE) has been recognized as the opposite phenomenon to the ordinary compatibility effect (i.e., RT of the compatible condition is slower than that of the incompatible condition). To investigate the NCE two experiments used a Stroop-like task in which students were asked to name the color of a centrally fixated square (target) while ignoring the peripheral color word (task-irrelevant stimulus). Ordinary compatibility effects were observed when the task-irrelevant stimulus was located near the target, whereas an NCE was observed when it was distant from the target. The NCE was not dependent on the response modality (i.e., oral or manual). These results could not be explained by a previous hypothesis that a misled spatial attention, caused by a shape similarity of a target and a task-irrelevant stimulus, would produce an NCE. Thus an NCE would reflect an inhibitory processing mechanism at a post-categorical level.
