- 요약In sport, expert anticipation is marked by an ability to utilize distributed motion information across an opponent's body. Conversely, novices rely more on single body segments for anticipation. These skill differences in attentional distribution may be due to how motion is processed - more globally or locally. Global processing involves simultaneous extraction and organization of information across multiple body segments, while local processing involves perception of individual body segments. Neural oscillatory frequencies can index global (right parietal activity) and local (left parietal activity) stimulus processing. This body of work aimed to use neural indices and visual manipulations to uncover skill-related differences in biological motion processing. In the first experiment, skilled and less-skilled soccer players responded to videos of penalty kicks that were temporally occluded at foot-ball contact under normal, blurred, or spatially occluded (only showing the hips) viewing conditions, with the latter two conditions emphasizing global and local information respectively. Skilled players outperformed less-skilled players, and performance only suffered in the hips-only condition. The hips-only condition elicited significantly greater beta relative to alpha power (beta minus alpha), which is a marker for enhanced local processing. Furthermore, only skilled performers showed significant decreases in bilateral parietal beta power in the hips-only condition, revealing that the removal of global motion information has a more profound impact on stimulus processing for skilled players. A second experiment was implemented to further investigate skill-related motion processing in a different sport while testing attentional priming effects. Skilled and less-skilled beach volleyball players responded to videos of volleyball attacks that were temporally occluded before ball contact, and players were primed globally or locally through a Navon matching task. Skilled players were more accurate than less-skilled players across occlusion intervals and priming conditions. Global priming resulted in better performance for both skill groups, while local priming impaired only skilled performance. Skilled players showed significantly lower alpha and beta power in the right compared to left parietal region than less-skilled players. Neural markers highlight skilled performers have greater right hemispheric dominance which could be functional for global motion processing and inhibiting left hemispheric verbal-analytic functions.
