摘要

本研究評估巴金森症患者在Stroop測驗的表現。二十七名巴金森症患者（17名男性和10名女性，平均年齡63.3±10.5歲）和二十七名年齡配對的正常控制組（14名男性和13名女性，平均年齡63.5±9.2歲）接受Stroop測驗中的色塊叫色、叫字、以及色字不相符的文字叫色作業。相較於正常控制組，巴金森症患者在三種作業的反應速度慢，而且Stroop干擾效果大，顯示巴金森症患者在反應抑制的缺損。進一步的分析顯示，巴金森症患者在色塊叫色作業的速度慢可能是因為動作緩慢的問題，而不是因為顏色區辨認知有問題。結論是，巴金森症患者在Stroop測驗的三種作業的表現反映出動作反應和認知抑制的能力受損。

This study assessed the performance of patients with Parkinson's disease (PD) in the Stroop test. Twenty-seven patients with PD (17 men, 10 women; mean age, 63.3±10.5 years) and 27 age-matched controls (14 men, 13 women; mean age, 63.5±9.2 years) were administered the color-naming, word-reading, and incongruent color-word-naming tasks in the Stroop test. Compared with the normal control group, the PD group had slower speeds for all three tasks and greater Stroop interference, indicating a response inhibition deficit in PD patients. Further analysis indicated that slowness during color naming might be due to motor slowness, rather than a central cognitive processing problem in color discrimination. In conclusion, the performance of the PD group on the three tasks of the Stroop test suggests that the PD patients were deficient in motor responses and cognitive inhibitory abilities.
