Lynsey M. Power from the Department of Psychological Science at Ball State University conducted a study to assess whether grunting in a tennis match influences the performance of the opposing player. The study observed how the sound of grunting could potentially mask or hide the sound of the ball hitting the racket, according to Sinnet and Kingstone in 2010. The study involved thirty-three undergraduates from the University of British Columbia, who all reported having recreational tennis experience and normal vision and hearing.

During the study, participants watched videos of tennis players hitting different types of shots while speakers surrounding the computer would play white noise. The videos were of four different types; one with a grunt, one without a grunt, one ending at contact, and one ending 100 ms after contact. Participants had to identify the direction of the shot that occurred in the video as quickly and accurately as possible. The data showed that the participants were slower to identify the direction of the shot when sound was playing. This suggests that a grunting tennis player can have an advantage over their opponent, as the sound is distracting and can hide the sound of the ball hitting the racket.

The study accurately evaluated whether a grunt during a tennis match would affect the opposing player's performance. The researchers conducted tests to identify if sound was distracting when figuring out the direction of the ball after contacting the racket during a match. The test proved that the sound impacted the participants' reaction time. Multiple tests were given to the participants, making the data more reputable than it would have been based on one trial per participant. The analysis presented in the study is useful to the tennis world, as professional players can compare their stats with the findings of this study. A player's response time and accuracy are affected by the sound of a grunt. As a result, tennis players may learn to block out the grunt or learn how not to let it affect their play.

This study relates to things covered in class, including the perceptual process. Perception and recognition can occur in reverse order at times. A tennis player may perceive what's going on and recognize that the server is going to hit the ball, and then the grunt happens. This distracts the player, forcing them to return to perception, recognize where the ball is and continue play.

In conclusion, this study contributes to the perception of professional tennis players and highlights how grunting can influence their game. The study represents a real tennis match, and several tests were performed to ensure that the data obtained is reputable. The conclusion from this study holds weight, as the findings are represented in professional tennis player's stats.
