Characteristics of Expert Wheelchair Tennis Players According to Visual Selective Attention Preference (Motor Behavior)

Melissa Hunfalvay, Eye Response Technologies, Charlottesville, VA

Examination of the visual selective attention of expert wheelchair (WC) tennis players when viewing a serve revealed two distinct eye movement patterns according to research by Hunfalvay (2004). These results indicated that one group of expert WC athletes predicted the ritual and preparatory phases of the serve ahead of time (referred to as the WC Predictive group) while a second group watched the motion of the serve as it occurred in ‘real time’ on the videotape (referred to as WC Real Time group). As all participants were expert WC tennis players, these two distinct visual selective attention patterns seemed perplexing and instigated questions as to why these differences manifest. Hence the purpose of this research was to extend results from Hunfalvay (2004) in a systematic effort to understand why two distinct visual selective attention patterns emerged. A total of 43 expert WC participants from the original study were asked to complete a questionnaire pertaining to their past playing experiences and coaches. A total of twenty participants completed and returned the questionnaire, 9 WC Real Time participants (aged 18 - 44 years, M = 34.56, SD = 10.01) and 11 WC Predictive group participants (aged 19 - 54 years, M = 36.09, SD = 11.44). These WC tennis players were ranked from 1 – 48 on the International Tennis Federation tour between August 31st, 2002 to October 1st, 2003. Percentage and average results were calculated. Results revealed that the WC Predictive group participants played able-bodied (AB) tennis prior to playing WC tennis, for a shorter period of time than the WC Real Time group. The WC Predictive group played WC tennis for a longer period of time than the WC Real Time group. WC Predictive group participants had coaches who were more likely to be WC certified than those participants in the WC Real Time group. All respondents from the WC Predictive group reported believing that there were differences between returning serve as an AB verses a WC player, where as only half of the WC Real Time group reported believing that there were differences. These results are discussed in terms of the influences coaches have on the cues used by WC players and the unique qualities of WC compared to AB tennis.
