摘要：

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 rime of patients with Parkinson's disease compared to the control group but without a concomitant slowness to engage, shift, and disengage their attention.
