RODRIGUES, Paula C.; FREITAS, Cidália; VASCONCELOS, Maria Olga  and  BARREIROS, João. Manual preference in acoincidence-anticipation task: effects of varying the stimulus orientation. Rev. Port. Cien. Desp. [online]. 2007, vol.7, n.1, pp.109-115. ISSN 1645-0523.

The purpose of this study was to analyze the existing relationbetween performance in a coincidence-anticipation task, varying the orientationof the stimulus, manual preference and sex. Thirty one righthanders and 35 lefthandersof both sexes participated in this study (M=15.86±.92).The Dutch HandednessQuestionnaire was used (Van Strien, 1992) to evaluate manual preference andthe Bassin Anticipation Timer to evaluate the coincidence-anticipation, at aconstant speed of 8mph. Subjects were positioned to view a stimulus runway approachingfrom their left (LR), right (RL), or directly from the front, in a sagittalplan (C). The ANOVA 2x2x3 (manual preference, sex, direction of stimulus approach),with repeated measures in the last factor (p≤0,05), indicated that (i)all subjects performed better in the sagittal plan (ii) handedness as factordidn’t show statistical significance; (iii) males were more precise and lessvariable than females.

Keywords : coincidence-anticipation; stimulus approach; handedness.
