Figure 3 ‘ig. I. Emotional and Cognitive Counting Stroops modulate different anterior cingulate cortex (ACC) divisions. In companion studies performed ising the same group of young adult subjects during the same scanning session, he Emotional Counting Stroop activated the affective division (Ref. a), whereas he cognitive version of the Counting Stroop activated the cognitive division Ref. b). Examples of the interference portions of the two tasks are displayed yeneath the scan data (for example, the correct answer would be to press Utton number ‘4’ to indicate four items in the display). To test this hypothesized dichotomy directly, two Stroop-like interferenc: tasks with differing causes of interference (i.e. one cognitive and one affective were validated in fMRI studies run with the same subjects during the sam: scanning session. During the cognitive version of this task, sets of up to fou vertically tiled words appeared on the screen every 1500 ms. Subjects wer instructed to report by button press the number of words in each set, regard. less of their meaning. Neutral trials contained single semantic category com: mon animals (e.g. ‘dog’ written three times). Interference trials contained num ber words that were incongruent with the correct response (e.g. ‘three’ writter four times). In contrast, during the interference portion of the Emotiona
