摘要

The influence of physical exercise on executive functions is well established, but its effect on attentional biases toward emotional stimuli remains poorly understood. The present study aims to determine whether physical exercise influences attentional orientation toward pain-related stimuli. To provide a more precise measure of attention, we recorded eye movements while participants (N = 37) performed a dot-probe task. In this task, two facial expressions (pain-neutral or neutral-neutral) were presented simultaneously, followed by the appearance of a target at the location of one of the two stimuli. Participants were instructed to respond as quickly as possible by pressing the mouse button corresponding to the target’s location. The task was completed before, during, and after physical exercise (wall sit test). Eye-tracking data showed a shift in attentional allocation during physical exercise. This is characterized by a higher proportion of first fixations directed toward neutral faces and longer fixation durations on neutral faces during exercise. This pattern may reflect avoidance of pain-related stimuli, but alternative interpretations, such as a relative increase in the salience of neutral cues, cannot be excluded. Given the complexity of attentional biases and their dependence on multiple factors, further studies are needed to clarify the extent to which physical exercise influences attentional orientation.
