Perception during Action Observation in Combat Sports

Abstract : Visual perception is of particular relevance for action anticipation within human social interactions. Competitive sports offer a great possibility to study visual perception, as it is necessary to anticipate action intentions of team members and/or opponents within a highly restricted timeframe. We conducted an eye tracking experiment and examined differences between athletes and novices during action observation in combat sports. Participants were instructed to respond to images of punches and kicks by pressing a left or right button. The images depicted different points-in-time during movement execution. Reaction times, error rates, fixation durations, and fixation rates were analyzed. Results showed that participants reacted faster, produced less errors, and used fewer fixations of longer duration at later points-in-time compared to earlier ones. A group effect regarding reaction times indicated expertise differences between combat-sports athletes and novices. However, no expertise-dependent differences in fixation duration and fixation rates were found.
