A Study on the Cognitive Processing Characteristics of Perceptual Anticipation in Volleyball Players'Reception of Smashes:Correlated Evidence from Eye Movements and fNIRS
Perceptual anticipation is a pivotal factor determining the level of motor skills.High-level athletes may possess advantages in perceptual anticipation,yet the eye-brain interactive processing mechanism that enhances perceptual anticipation through sports experience remains to be further explored.This study selected volleyball match video materials and utilized eye-tracking and functional near-infrared spectroscopy(fNIRS)to investigate the behavioral performance and cognitive processing characteristics of the brain during perceptual anticipation of receiving smashes among volleyball players of different skill levels.The results showed that the accuracy rate was significantly higher and the reaction time was significantly shorter for the expert group than those for the novice group.Furthermore,the pupil diameter and saccade amplitude of the expert group were significantly shorter compared to the novice group.Regarding brain activation,the left ventrolateral prefrontal cortex,left dorsolateral prefrontal cortex,and right dorsolateral prefrontal cortex exhibited significantly lower activation levels in the expert group than that in the novice group.Notably,the activation level of the right dorsolateral prefrontal cortex and pupil diameter showed significant positive correlation;also,the activation level of the left ventrolateral prefrontal cortex and pupil diameter,and saccade amplitude respectively showed significant positive correlation.These findings suggest that high-level volleyball players possess advantages in perceptual anticipation,and long-term volleyball training facilitates coupling of visual and brain information processing rapidly.
