Field dependence and reaction time in senior tennis players (65 and over).

Rod-and-frame errors and speed of response are both thought to reflect, in part, differential ability in selective attention, or one's ability to focus on the salient perceptual factors of a given environment. The present study involved an investigation of 18 "super-senior" tennis players aged 70 yr. and over who participated in the national championship tournament. Their data were compared with the data from a similar aged heterogeneous group. The super-seniors were significantly more field independent and had much more rapid simple reaction times and total-body response time than their counterparts.
