Abstract/Description: The general purpose of this investigation was to study the differences between high-skill and intermediate-skill tennis players in gaze behaviors while performing tennis serve returns. Participants were asked to return 40 serves in the four different serve locations while wearing a mobile eye-tracker and their return performance was measured using a point system based on the ball’s first bounce that gave higher values to deep and angled returns. The study examined fixation’s onset and duration to four distinct locations: ball before bounce, the bounce area, ball after bounce, and impact zone. In addition, quiet-eye (QE) onset and duration were analyzed. Furthermore, the location of the racket-ball contact in relation to an egocentric frame of reference was calculated. Two-way and RM ANOVAs were used to test the hypotheses related to gaze behaviors. In addition, an analysis of coordinates and centroids were used to analyze egocentric gaze. Results indicated that high-skill players and shots classified as high score were characterized by fewer fixations of longer duration. Likewise, high-skill players displayed earlier QE onset and longer QE duration, in comparison to their less skilled counterparts. A comparison in QE between high-scores and low-scores shots revealed that the former were also characterized by an earlier QE onsets and longer QE. Pertaining to egocentric gaze, it was observed that high-skill players had a higher number of racket-ball contacts that occurred in central vision. Moreover, forehand and backhand racket-ball contacts were closer to the center in high-skill players, whereas intermediate skill players had racket-ball contacts further from the midpoint. Gaze behavior findings are discussed in the framework of the established relationship between QE periods, expertise, and performance. Egocentric gaze findings are discussed in relation to expertise-based differences in head stabilization and prediction of the ball-racket location. Limitations of the current study and suggestions for future studies are presented. To the author’s knowledge, this study is the first to analyze QE gaze behaviors in situ and the first to empirically test the role of egocentric gaze in tennis serve returns. Findings provide valuable insight into the relationship between gaze behaviors, QE periods, egocentric gaze, and expertise in a fast pace interceptive sports.
