摘　　要：结合专家-新手范式与ERP技术,研究网球运动专长对个体深度运动知觉产生的影响。通过记录网球专家和新手各19名进行深度运动模式判断时的行为和ERP数据,比较两组个体深度运动知觉的行为反应差异和脑电特征。结果显示,网球专家组深度运动知觉的判断准确率高于新手组;新手组在球体靠近时P1(PO7点)的潜伏期比球体远离时的潜伏期长,专家组无显著性差异;专家组在球体靠近时的P2(Oz点)成分潜伏期长于球体远离时的潜伏期。结果表明,网球运动专家的深度运动知觉能力在准确性上较新手高;运动专长效应与选择性注意资源的调用以及模式识别有关;枕区P2成分可作为深度运动知觉的评价指标。Perception of motion-in-depth is essential to guide and modify drive action in interceptive-dominated sports. Tennis players usually exhibit better performance in perception of motion-in-depth. There is considerable evidence for cognitive advantages of sports expertise, but the neural mechanisms of these benefits remain poorly understand. The purpose of this study is to investigate the effect of motor expertise on perception of motion-in-depth by event-related potential（ERP） with expert-novice paradigm.Two groups of volunteers,one comprising 19 expert tennis players with skill level 2（trained for at least 5years）and the other 19 novices,participated in the experiment.There were six videos made as the stimuli of the experiment,including four target stimuli（a directly-approaching sphere,a directly-receding sphere,a rotating approaching sphere and a rotating receding sphere）and two non-target stimuli（an expanding circle plane and a contracting circle plane）.In each trial,participants watched one video and were asked to identify the target and its motion direction as quickly as they could（if the participant didn’t response in one second,the video ended and it would be considered as a wrong answer）.Their reaction time,accuracy and EEG data were recording synchronously when participants completed the cognitive task of motion-in-depth perception.There were a total of 360 trials divided into three blocks of 120 trials each.Each block included 20 repetitions of the six stimuli.ERP data of five electrode sites was selected for further statistical analysis：PO7 and PO8 for P1 and N180,Oz for P2,CPz and Pz for P300.Peak amplitudes（baseline-peak measured）and corresponding latencies were detected in four windows following stimulus onset：80~160 ms（P1）,160~220 ms（N180）,220~280 ms（P2）,and320~580 ms（P300）.Experimental design with 2 factors（direction of motion in depth：approaching vs.away）×2 factors（rotation pattern：rotating vs.non-rotating）were adopted and further repeated
