Gaze control during interceptive actions with different spatiotemporal demands

Area of Science:

• Sports Science
• Motor Control
• Human Movement

Background:

• Interceptive actions rely on spatiotemporal information, but how this information is acquired under conflicting constraints is unclear.
• Existing research lacks evidence on adapting information pickup for interceptive actions facing varied task demands.

Purpose of the Study:

• To investigate how spatiotemporal constraints affect performance, timing, and gaze in interceptive actions.
• To examine expert futsal goalkeepers' visual strategies during penalty kicks under different distance conditions.

Main Methods:

• Expert futsal goalkeepers participated in an in situ interceptive action task.
• Penalty kicks were administered from two distances (10 m and 6 m) to manipulate spatiotemporal constraints.
• Performance metrics, action initiation timing, and gaze patterns were recorded and analyzed.

Main Results:

• Goalkeepers achieved higher save rates and initiated actions later under less constrained conditions (10 m kicks).
• Gaze patterns shifted, with longer fixation on the ball relative to the kicker's body at 10 m.
• Gaze variability decreased towards the end of the action, forming a funnel-like pattern, especially under tighter constraints.

Conclusions:

• Changes in spatiotemporal demands significantly influence the selection and use of visual information for controlling interceptive actions.
• Expert goalkeepers dynamically adjust their information pickup strategies to meet task-specific constraints.
• Findings highlight the adaptive nature of visual perception in expert motor performance.
