ERP Influence of Velocity Structure and Direction Cue on the Coincident-timing of Tennis Landing

Abstract

Abstract According to the classic research paradigm of Bassin Anticipation Timer (Bassin), a tennis ball Coincident-timing stimulus material with highly representative ecological validity is designed. To explore the behavioral and ERP characteristics of tennis players' landing synchronization timing under different speed structure and direction cues. The behavioral results show that the timing error of the slow condition is higher than that of the fast condition, and the timing error of the right drop point is higher than that of the middle and left drop point. ERP results showed that the right hemisphere parietal region, parietal occipital region and occipital region of P1 and P2 showed higher amplitude than that of the left hemisphere, and the latency of P1 in the right drop point of the fast group was later than that in the middle and left drop point, and later than that in the slow group. The amplitude of N1 and N2 components induced by the right drop point was higher than the left drop point, and the latency of the right and middle drop point of N1 was later than the left drop point. The amplitude of P3 induced by the left occipital region and parieto-occipital region was higher than the left and right points, and the amplitude of Po7 was higher than the left point. The incubation period of P3 in the middle and left drop point of fast group was higher than that in the right drop point, and that in the slow drop point of right drop point was higher than that in the fast group. The electrode amplitude in the parietal and parietal occipital regions of LPP components was higher than that in the frontal and central regions. The amplitude of the right frontal area, the middle, the left frontal area and the left parietal pillow area were the highest. Conclusion: There is an inverted U-shaped relationship between speed stimulation and physiological arousal, and the direction level is closely related to motor expertise experience and dominant eye. The latency time of the parietal and parietal occipital regions and the suppression control of the central region of ERP components have great influence on the timing error between the speed groups. The timing errors in different directions showed the advantage of the right hemisphere cognitive processing in the early stage, and the difference of the amplitude was mainly reflected in the activation intensity of the parietal, parietal and occipital regions, while the advantage of the right hemisphere cognitive processing gradually weakened in the late stage.
