incongruent conditions. This task has the advantage over the classical color-naming Stroop in that it does not depend on skilled automatic reading (since poor readers will do paradoxically better on the classic Stroop). Functional neuroimaging studies have shown that for both Color and Counting Stroop, the incongruent condition activates the ACC relative to the congruent condition (Bush et al., 1998). For the Stroop task, the reaction time difference score (reaction time difference between incongruent and congruent conditions) was the dependent measure used in our analyses.
