Grunting during tennis leads to 'slower response, more decision errors'

Washington, Oct 2 (ANI): A researcher at University of Hawaii at Manoa has found that when players grunt with every tennis shot, it slows down their responses and causes them to make more decision errors.

Scott Sinnett, assistant psychology professor at the University of Hawaii at Manoa, found the potential detrimental effect that noise has on shot perception during a tennis match.

Thirty-three undergraduate students from the University of British Columbia viewed videos of a tennis player hitting a ball to either side of a tennis court; the shot either did or did not contain a brief sound that occurred at the same time as contact.

The extraneous sound resulted in significantly slower response times, and significantly more decision errors, confirming that both response time and accuracy are negatively affected.

"This is the first study to look at the issue of grunting in tennis. Our current work is also looking at how advanced and professional tennis players perform, to determine if they have developed any strategies to limit the negative effects of a grunting opponent," said Sinnett.

Sinnett and Kingstone noted that these consequences on faster tennis surfaces, such as the grass courts of Wimbledon or hard courts of the Australian and U.S. Open, are likely to be profound. (ANI)
