Abstract

There were three primary objectives: to examine the usefulness of the Stroop interference effect as a measure of frontal lobe function; to investigate the possibility of distinct lesion effects for word reading or color naming; and to specifically determine the brain regions necessary for the performance of the incongruent condition. Fifty-one patients with single focal brain lesions in frontal and non-frontal regions and 26 normal control subjects (CTL) were administered the word reading, color naming and incongruent conditions of the Stroop task. Only frontal lesions produced significant impairment. Patients with posterior lesions were not significantly deficient in any condition. Damage to the left dorsolateral frontal lobe resulted in increased errors and slowness in response speed for color naming. Contrary to Ferret (Neuropsychology, 1974; 12: 323-330), lesions of the left frontallobe did not result in a selective interference deficit on the Stroop incongruent condition. Father, bilateral superior medial frontal damage was associated with increased errors and slowness in response time for the incongruent condition, This result is interpreted as failure of maintenance of consistent activation of the intended response in the incongruent Stroop condition. The results and conclusion are compatible with the prevalent theoriesof both the Stroop effect and the role of the superior medial frontal regions. The role of the anterior cingulate cortex on performance of the Strooptask is likely related to task and patient context. (C) 2001 Elsevier Science Ltd. All rights reserved.
