Promotion of Deviation Decisions in Table Tennis Players by Internal ModelA Quantitative Analysis Based on the HDDM

Object  Based on the perception-action double-system theory, this study selects the table tennis serve as the research object and uses the Drift Diffusion Model (DDM) to explore how motor experience affects the ability to monitor action anticipation deviations.

Methods By quantifying the starting point and drift rate parameters in DDM, the study measures the effective deviation perception based on the internal model and the accumulation speed of deviation evidence during the action control process, achieving a quantitative separation of perception and action decision processes.

Results  Players exhibited higher sensitivity to deviation perception, with their starting points being influenced by the degree of deviation, while novices were not affected. Moreover, the players' group showed more refined adjustments in the drift rate with changes in deviation degree.

Conclusion Motor experience produces the effect on action anticipation and deviation monitoring processes by optimizing the internal model and forming specific cognitive strategies, revealing the multi-level role of cognitive processing in high-level elite players.
