Perception-action coupling during discriminative interceptive actions

Interception is a complex task that requires the integration of perception and action under temporal constraints. Decision-making about whether to respond moving stimuli involved in discriminative responses may further increase cognitive load imposed on performer, influencing perception-action coupling during interception. This study investigated effects response requirements eye hand movements, action, accuracy interceptive actions. Twelve right-handed male participants performed actions at three velocities (0.53 m/s, 0.66 0.88 m/s) (target-specific) non-discriminative (target non-specific) conditions. While condition required presented all trials, them stimulus toward pre-defined target area. Timing errors were greater than condition, increased with increasing velocity. Both reaction movement times decreased velocity, longer condition. Variables representing aspects actions, including saccadic latency, frequency, gaze duration, Compared frequency was higher, duration shorter, spatial responses, radial error, couplings hand, however, remained unaffected by These findings suggest decision-making impair delaying without severe influences

Abstract Interception, essential for activities like driving and sports, can be characterized by varying degrees of predictive behaviour. We developed a visually guided task to explore how target predictability visibility influenced interception actions. The featured falling dot horizontal velocity, gravity air friction, with manipulated through external forces that altered the target's trajectory. also introduced spatial occlusion limit visual information. Our results show low variability favoured behaviours, while high led more reactive responses relying on online feedback. Manual displayed increased changes in motion, whereas eye trajectories maintained constant curvature across conditions. Additionally, higher delayed onset hand movements but did not affect movement onset, making gaze position poor predictor position. This distinction highlights different adaptive patterns response trajectory changes. Participants stable behaviours within sessions, indicating individual preferences either or findings reveal dynamic interplay between interception, illustrating humans combine manage variability.
