The present study explored the intrinsic event-related potential (ERP) features of the effects of acute psychological stress on the processing of motion-in-depth perception using a dual-task paradigm. After a mental arithmetic task was used to induce acute psychological stress, a collision task was used to evaluate motion-in-depth perception. The error value and average amplitude of late slow waves (SW) were significantly larger for the earlier colliding spheres' than for the later colliding spheres. The P1 peak latency in the left occipital region was significantly shorter than that of the right occipital region in the motion-in-depth perception task. Compared to the control condition, the estimated value of residual time-to-collision and error value were significantly reduced, and the N1 peak amplitude and the SW averaged amplitude were significantly increased in the stress condition. Longer motion-in-depth time improved discrimination accuracy and decreased the investment of cognitive resources. Acute psychological stress increased behavioral performance and enhanced attention resources on the motion-in-depth perception task together with greater investment of cognitive resources.

急性心理压力对运动深度感知的影响：一项事件相关电位研究。

本研究使用双任务范式探讨了急性心理压力对深度运动感知处理影响的内在事件相关电位（ERP）特征。在使用心算任务诱发急性心理压力后，使用碰撞任务来评估运动深度感知。较早碰撞球体的晚期慢波（SW）的误差值和平均振幅明显大于较晚碰撞球体。在深度运动感知任务中，左枕叶区的 P1 峰值潜伏期明显短于右枕叶区。与控制条件相比，应力条件下剩余碰撞时间估计值和误差值显着减小，N1峰值幅度和SW平均幅度显着增大。较长的深度运动时间提高了辨别准确性并减少了认知资源的投入。急性心理压力提高了行为表现，增强了对运动深度感知任务的注意力资源，同时增加了认知资源的投入。
