Cognitive complexity and the validity of clinicians' judgments.
Efforts to explain why some neuropsychologists are more accurate than others have been unsuccessful. In the present study, the relation between the cognitive complexity of clinicians and the validity of their judgments was investigated. Forty-two neuropsychologists completed a measure of cognitive complexity. The hypothesis that neuropsychologists who are high in cognitive complexity will be more accurate than those who are low in cognitive complexity was not supported. It is not clear why cognitive complexity was not significantly related to the validity of diagnostic ratings: One explanation is that the measure of cognitive complexity used in this study was inadequate but another possibility is that neuropsychologists who are low in cognitive complexity may still be able to achieve high levels of accuracy if they attend to normative data when they interpret test results.
