Right- and left-handers differ when compared in some motor tasks, and left-handers enjoy some advantage over right-handers in visuo-motor tasks. In this study we intend to analyze the effect of stimulus speed, in a simple coincidence-anticipation task, depending on handedness. Twelve right-handers and twelve left-handers of both sexes, students of Physical Education, participated in this study. The Bassin Anticipation Timer was used to evaluate the coincidence-anticipation ability at three different and random velocities: 268 cm/s, 402.3 cm/s e 536.4 cm/s (6, 9 e 12 mph, respectively). The subjects were evaluated performing the task with the preferred hand and non-preferred hand. The results revealed that: 1) only right-handers were affected by the variable stimulus speed, anticipating responses and being more variable at 268cm/s, while at 402.3 cm/s and 536.4 cm/s responses were late; moreover they were less variable at 536.4cm/s; 2) sex as a main factor was significant only in the left-handed group, males being more accurate and less biased in their responses than females; 3) manual asymmetry was only apparent in the left-handed group at the 268cm/s and in the variable error. The perceptual component of the task seems to be crucial in distinguishing right-handers and left-handers where the speed of the stimulus is manipulated.Downloads
