The precueing paradigm developed by Posner has been used to examine visuospatial shifting of attention. In the current study, we modified such a paradigm so that it could be studied in nonvisuospatial domains and its component processes of disengagement, movement, and engagement could be analyzed in a similar fashion to the visuospatial domains. 14 patients with Parkinson's disease and 14 normal controls matched for age, sex, handedness, and years of education served as subjects. The speed of shifting attention was measured using the cost and benefit analysis. Analyses showed an over-all slowness in reaction time of patients with Parkinson's disease compared to the control group but without a concomitant slowness to engage, shift, and disengage their attention.
波斯纳开发的预提示范式已被用于研究注意力的视觉空间转移。在当前的研究中，我们对该范式进行了修改，使其能够在非视觉空间领域进行研究，并且其分离、移动和参与的组成过程能够以与视觉空间领域类似的方式进行分析。14名帕金森病患者和14名在年龄、性别、利手和受教育年限方面相匹配的正常对照者作为研究对象。使用成本效益分析来测量注意力转移的速度。分析表明，与对照组相比，帕金森病患者的反应时间总体较慢，但在注意力的参与、转移和分离方面并没有相应的迟缓。
