A previous article reported opposite turning behavior in right-handers and non-right-handers (C. Mohr. T. Landis, H. S. Bracha, & P. Brugger, 2003). This observation appears contradictory to the 1st study on long-term spontaneous turning behavior in healthy participants (H. S. Bracha, D. J. Seitz, J. Otemaa, & S. D. Click, 1987). These latter authors found a complex interaction between hemispheric dominance, preferred turning side, and sex. C. Mohr et al. (2003) argued that the differentiation of the population in hemisphere-dominant groups by a compound measure of hand-foot-eye preference might have masked their recent finding. Thus, this commentary presents a reanalysis of the original data set (H. S. Bracha et al., 1987). Replicating recent observation, right-handers preferred left-sided turns; and non-righthanders, right-sided turns. This replication strengthens the proposition that handedness and turning behavior might depend on interhemispheric dopamine asymmetries.
先前有一篇文章报道了右利手和非右利手的相反转向行为(C. 莫尔、T. 兰迪斯、H. S. 布拉查和P. 布鲁格,2003年)。这一观察结果似乎与关于健康参与者长期自发转向行为的第一项研究相矛盾(H. S. 布拉查、D. J. 塞茨、J. 奥泰马和S. D. 克里克,1987年)。后一组作者发现半球优势、偏好转向侧和性别之间存在复杂的相互作用。C. 莫尔等人(2003年)认为,通过手-足-眼偏好的复合测量对人群进行半球优势分组可能掩盖了他们最近的发现。因此,本评论对原始数据集(H. S. 布拉查等人,1987年)进行了重新分析。重复最近的观察结果,右利手更喜欢向左转向;而非右利手则更喜欢向右转向。这一重复加强了利手和转向行为可能取决于半球间多巴胺不对称的观点。
