COVERT ORIENTING TO CENTRAL VISUAL CUES AND SPORT PRACTICE RELATIONS IN THE DEVELOPMENT OF VISUAL-ATTENTION

This study examines the development of controlled covert orienting of visual attention, according to the age and the level of performance of tennis players. Practicers and nonpracticers age 13, 16, and 25 participated in a covert orienting task. On each trial, subjects responded to a target which appeared in one of four locations arrayed horizontally across the display. Three central cues were used: neutral, the cue did not specify in which location the target would appear; valid, the target was present in the cued location on 80% of the trials; invalid, the target was present in one of the uncued locations on the remaining 20% of the trials. The results showed that (1) practicers were not faster than nonpracticers in processing the signals, (2) observers of all ages oriented attention voluntarily to the cued locations, (3) central cues had a smaller effect on older and practiced subjects, and (4) developmental and sport practice factors had similar effects on orienting efficiency. The implications of these findings for theories of attentional development are discussed. © 1992.
