Recent investigations indicate that an iris pigmentation-motor behavior exists, but may be limited to the reaction time component of a motor task. The absence of differences in peripheral nervous conduction (Wolf and Landers, 1978) suggests that a central nervous system mechanism may be operating, possibly dependent on the characteristics of neuromelanin or catecholamine turnover. Experiment 1 tested this notion by fractionating simple reaction time into the premotor and motor components by electromyography. ANOVA revealed that dark-eyed subjects had faster total reaction times and premotor times, but only the premotor time component approached significance (p < 0.07). Experiment 2 fractionated patellar reflex time of light-eyed and dark-eyed subjects into reflex lagency and motor components. There were no eye color differences for any of the reflex time measures. The results of Experiments 1 and 2 support a central nervous system explanation for the iris pigmentation-reaction time phenomenon.
最近的研究表明，存在一种虹膜色素沉着 - 运动行为，但可能仅限于运动任务的反应时间成分。外周神经传导方面不存在差异（沃尔夫和兰德斯，1978年），这表明可能有中枢神经系统机制在起作用，可能取决于神经黑色素或儿茶酚胺代谢的特征。实验1通过肌电图将简单反应时间分为运动前和运动成分来验证这一观点。方差分析显示，深色眼睛的受试者总反应时间和运动前时间更快，但只有运动前时间成分接近显著水平（p < 0.07）。实验2将浅色眼睛和深色眼睛受试者的髌反射时间分为反射潜伏期和运动成分。任何反射时间测量中均无眼睛颜色差异。实验1和2的结果支持对虹膜色素沉着 - 反应时间现象的中枢神经系统解释。
