PURPOSE: This study examined the effects of sports experience on visual attention and brain activity during map symbol representation tasks in orienteering athletes.
METHODS: A single-factor between-subjects design (Skill Level: expert vs. novice) was used. Behavioral, visual attention, and brain activity data were collected simultaneously using eye-tracking and functional near-infrared spectroscopy (fNIRS).
RESULTS: Compared to novices, experts exhibited significantly higher accuracy and lower reaction times. Experts also showed lower fixation frequency, reduced saccade amplitude, and more concentrated fixation hotspots. Neural analyses revealed significantly lower activation in the bilateral dorsolateral prefrontal cortex (DLPFC), bilateral temporal cortex, and left parietal cortex in experts, alongside stronger functional connectivity. Saccade amplitude was positively correlated with bilateral DLPFC activation.
CONCLUSION: High-level orienteering athletes exhibit domain-specific cognitive advantages in map symbol representation tasks. Long-term orienteering map reading training facilitates synergistic interactions between visual and neural information processing.
