摘要：

Binary choice task has been poorly evaluated in patients with focal brain damage. We assessed the decision process in normal subjects and patients with frontal or posterior brain damage using a unimanual two-choice response time (CRT) paradigm. The decision was manipulated by varying the response probability and parameters were analysed with the relative judgement theory. The results suggest that the binary decision process is spared in patients with focal lesions and that their longer CRT is mainly related to slowing the perceptual or motor stages. The prominent role of the left hemisphere in binary choice received support. Copyright (C) 1996 Elsevier Science Ltd
