Description:
Conflict monitoring by the anterior cingulate cortex (ACC) has been posited to signal a need for greater cognitive control, producing neural and behavioral adjustments. However, the very occurrence of behavioral adjustments after conflict has been questioned, along with suggestions that there is no direct evidence of ACC conflict-related activity predicting subsequent neural or behavioral adjustments in control. Using the Stroop color-naming task and controlling for repetition effects, we demonstrate that ACC conflict-related activity predicts both greater prefrontal cortex activity and adjustments in behavior, supporting a role of ACC conflict monitoring in the engagement of cognitive control.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kerns, John G -- Cohen, Jonathan D -- MacDonald, Angus W 3rd -- Cho, Raymond Y -- Stenger, V Andrew -- Carter, Cameron S -- New York, N.Y. -- Science. 2004 Feb 13;303(5660):1023-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychological Sciences, University of Missouri-Columbia, Columbia, MO 65211, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14963333" target="_blank"〉PubMed〈/a〉
