A Study of Cognitive Processing Characteristics of Perceptual Prediction of Serve-Receive in Volleyball Players from Perspective of Eye-Brain Interaction
Objective:Exploring the visual-motor cognitive processing characteristics in the Process of perceptual prediction of serve-receiving in volleyball players at different levels.Methods:21 high-level volleyball players at national first-grade level or above(expert group)and 21 physical edu-cation majors from volleyball clubs(novice group)were selected.Eye-tracking and functional near-infrared spectroscopy technologies were utilized to synchronously investigate the behavior-al performance and neural mechanisms of the brain during the perceptual prediction process in volleyball players at different levels.Results:1)The accuracy of the expert group was signifi-cantly higher than that of the novice group(P<0.05),and the reaction time was significantly lower(P<0.05);2)both the pupil diameter and saccadic amplitude of the expert group were significantly lower than those of the novice group(P<0.01);3)the activations level of R-DLP-FC,frontal pole region,and L-VLPFC in the expert group were significantly lower than those in the novice group(P<0.01);4)there was a significant negative correlation between the accura-cy and both pupil diameter and saccadic amplitude in the expert group(P<0.05),the accuracy in the expert group showed a significant negative correlation with the activation levels in the R-DLPFC and L-VLPFC(P<0.05),the activation level in the R-DLPFC in the expert group was significantly positively correlated with pupil diameter(P<0.05),while the activation level in the L-VLPFC was significantly positively correlated with both pupil diameter and saccadic am-plitude(P<0.05).Conclusions:Expert volleyball players show special cognitive advantages in the process of perceptual prediction.Their visual search patterns are more concise and clear;they show lower activation levels in the R-DLPFC,R-FPA,and L-VLPFC;visual information capture is coupled with prefrontal cortex processing and handling,and perceptual prediction is rapid and effective,demonstrating the characteristics of cognitive processing automation.
