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.

急性心理压力对深度运动知觉的影响：一项与事件有关的潜能研究。

本研究探讨了使用双任务范式对急性心理压力作用于深度运动知觉处理的内在事件相关电位（ERP）特征。在使用心理算术任务诱发急性心理压力后，使用碰撞任务评估深度运动知觉。较晚的碰撞球体的迟慢波（SW）的误差值和平均振幅明显大于较晚的碰撞球体。在深度运动感知任务中，左枕骨区域的P1峰值潜伏期明显短于右枕骨区域的P1峰值潜伏期。与控制条件相比，剩余碰撞时间的估计值和误差值显着降低，在应力条件下，N1峰幅度和SW平均幅度显着增加。更长的深度运动时间可提高判别准确性，并减少认知资源的投入。急性心理压力增加了行为表现，并在深度运动感知任务上增加了注意力资源，同时加大了对认知资源的投入。
