Perception of motion-in-depth is essential to guide and modify the hitting action in interceptive-dominated sports (e.g., tennis). The purpose of this research was to investigate the effect of tennis expertise on motion-in-depth perception at different cognition processes by two event-related potential (ERP) studies. Specifically, the study explored differences in behavior and electroencephalogram (EEG) characteristics between tennis experts and novices under two different task conditions. Seventeen skilled tennis players (average professional experience: 10.76 ± 2.56 years) and 17 age-matched novices participated in two experiments. Cortical activity (P1, N1, P2, and the later component) and task performance (reaction time, accuracy rate, and error value) were recorded when participants completed a direction-identifying task (Experiment 1) and a prediction-motion task (Experiment 2) while perceiving motion-in-depth. Results demonstrated that P1 latency in the expert group was significantly shorter than the novice group in experiment 1; and in experiment 2, the expert group showed shorter P1 latency than the novice group under the TTC1 (actual time-to-collision is 400 ms) condition. The results indicate that the effect of tennis expertise on motion-in-depth perception was primarily manifested as early visual attentional investment in the features of objects. Experts have the rapid inbibition of invalid attention.
深度运动知觉对于在以拦截为主的运动（如网球）中指导和调整击球动作至关重要。本研究旨在通过两项事件相关电位（ERP）研究，探讨网球专业技能在不同认知过程中对深度运动知觉的影响。具体而言，该研究探讨了在两种不同任务条件下，网球专家和新手在行为和脑电图（EEG）特征上的差异。17名熟练的网球运动员（平均专业经验：10.76 ± 2.56年）和17名年龄匹配的新手参与了两项实验。当参与者在感知深度运动时完成方向识别任务（实验1）和预测运动任务（实验2）时，记录其皮层活动（P1、N1、P2及后续成分）和任务表现（反应时间、准确率和错误值）。结果表明，在实验1中，专家组的P1潜伏期显著短于新手组；在实验2中，在TTC1（实际碰撞时间为400毫秒）条件下，专家组的P1潜伏期比新手组短。结果表明，网球专业技能对深度运动知觉的影响主要表现为对物体特征的早期视觉注意力投入。专家能够快速抑制无效注意力。
