A modified version of the odd-man-out test was used to investigate set-shifting aptitude in 12 patients with Parkinson's disease. We asked subjects to execute in alternation two different sorting rules over successive items. External and internal cueing conditions were employed. Patients with Parkinson's disease were impaired on the tasks with internal cues but were normal on the tasks with external cues. Moreover, the shift costs were consistently larger for the shift to the easier task than the shift to the more difficult task. These findings indicated that the model of 'Supervisory Attentional System' may not be sufficient to explain the data as Brown and Marsden (1988) originally suggested.
采用一种改良版的淘汰测试来研究12名帕金森病患者的转换能力。我们要求受试者对连续的项目交替执行两种不同的分类规则。采用了外部提示和内部提示条件。帕金森病患者在内部提示任务中表现受损，但在外部提示任务中表现正常。此外，转向较简单任务的转换成本始终高于转向较困难任务的转换成本。这些发现表明，“监督注意系统”模型可能不足以像布朗和马斯登（1988年）最初所建议的那样解释这些数据。
