Studies have found that athletes outperformed non-athletes in mental rotation tasks with both object-based and egocentric transformations (ET), but the effect of sport expertise on the processing stages (i.e., perceptual stage, rotation stage, and decision stage) remains conflicted. Bearing the view that the stages occur sequentially and the high temporal resolution of event-related brain potentials, this study focused on brain processing during mental rotation and was designed to determine the time course of electrophysiological changes in athletes and non-athletes. A total of 42 divers and non-athletes were recruited for the study. A mental body rotation task with object-based and egocentric transformation conditions was conducted, and the reaction time (RT), accuracy, performance stages, N2 latency, amplitude, and the amplitude of rotation-related negativity (RRN) were recorded. Behavioral results demonstrated higher accuracy for athletes at 120° and 180°. Moreover, as compared to non-athletes, the enlarged amplitude of N2 and RRN were confirmed in both transformations for athletes and were correlated with the performance stages and athletes' professional training years. The present study provided a deeper insight into the relationship between sports training, behavior performance, and brain activity.
研究发现，在基于物体和以自我为中心的转换（ET）的心理旋转任务中，运动员的表现优于非运动员，但运动专业技能对处理阶段（即感知阶段、旋转阶段和决策阶段）的影响仍存在争议。基于心理旋转阶段按顺序发生以及事件相关脑电位具有高时间分辨率的观点，本研究聚焦于心理旋转过程中的大脑处理，并旨在确定运动员和非运动员电生理变化的时间进程。本研究共招募了42名潜水员和非运动员。进行了一项具有基于物体和以自我为中心转换条件的心理身体旋转任务，并记录了反应时间（RT）、准确率、表现阶段、N2潜伏期、波幅以及旋转相关负波（RRN）的波幅。行为结果表明，运动员在120°和180°时的准确率更高。此外，与非运动员相比，运动员在两种转换中N2和RRN的波幅均增大，且与表现阶段和运动员的专业训练年限相关。本研究为体育训练、行为表现和大脑活动之间的关系提供了更深入的见解。
