Subject demographics and rejected trials and subjects in the analyses comparing PD patients on and off medication.

Trials were rejected due to the criteria for button press and eye movements (Table 1, see Methods). Subjects were rejected if more than half their trials in either of their on or off sessions was rejected. In total, we rejected 7 subjects (4 patients were rejected both sessions while the other 3 patients were rejected in one of the sessions).

因按键与眼动判定标准（见表1，详见方法部分），部分实验试次被剔除。若被试在其任务开启或关闭时段中，超过半数的试次遭到剔除，则该被试整体被剔除。最终共有7名被试被剔除：其中4名患者的两个时段的试次均被剔除，剩余3名患者仅在其中一个时段的试次被剔除。
