Abstract: | The anterior cingulate cortex (ACC) is involved in cognition and emotion. In the classic Stroop task, presentation of stimuli
that are in response conflict with one another produces activation in the caudal ACC. In the emotional Stroop task, presentation
of emotionally salient stimuli produces activation in the rostral ACC. Presentation of stimuli that are emotionally conflicting
should activate the caudal ACC; stimuli that are emotionally salient should activate the rostral ACC. We tested this prediction
using functional magnetic resonance imaging while subjects made emotional valence judgments of words overlaid on emotional
faces (word-face Stroop task). Emotionally incongruent pairs were responded to more slowly than emotionally congruent pairs.
Emotionally incongruent trials were associated with increased activation within the caudal ACC, whereas no ACC activation
was found in response to emotional saliency. These results support the conflict-monitoring model of caudal ACC and extend
this function to conflict within the domain of emotional stimuli. |
