In two experiments with an Odd-Man-Out choice discrimination task, Parkinsonian subjects had difficulty in alternating between two rules on successive trials. The pattern of errors suggested that the difficulty arises from an instability of cognitive set rather than any loss of reasoning ability, perseveration or increased distractibility.
在两项采用“与众不同”选择辨别任务的实验中,帕金森病患者在连续试验中难以在两条规则之间进行切换。错误模式表明,这种困难源于认知定势的不稳定性,而非推理能力的丧失、持续性或注意力分散增加。
