The construct of cognitive style in relation to cognitive disposition was investigated by means of a task involving conflicting cues or cognitive distractors, the Stroop test. Differences in cognitive disposition were obtained by using Ss, showing psychopathology: schizophrenics, psychoneurotics and normals. Schizophrenics showed the most interference from the distractors and normals the least. These results are discussed according to Peters' intensional-extensional hypothesis indicating that an intensional attentive attitude is more characteristic of the thought processes of schizophrenics than of normals and that psychoneurotics hold an intermediate position between these two extreme groups.
