SCHIZOPHRENIA AND REVERSE-STROOP INTERFER ENCE IN THE GROUP VERSION OF THE STROOP AND REVERSE-STROOP TEST

Previous stiudies showed that attentional task performance of schizoph erenics was significantly inferior to that of normals. The classical S troop Color-Word Interference Test is an example of such attentional t asks and performance on the ''reverse'' Stroop task is reported to dis criminate schizopherenics from normals better than the regular Stroop task. These results suggest that schizophrenics are more susceptive to ''reverse'' Stroop interference in reading incongruent word-color com binations than normals. The group version of the Stroop and reverse-St roop Color-Word Test, where the respose is to choose a matching altern ative, was used to test the hypothesis. The results virtually supporte d the hypothesis. In addition, interference was closely related to the patient's control of impulsiveness. It was suggested that schizophren ics have generation (or translation) deficits between differents codes .
