Evidence analysed based on reaction time has contributed to the development of cognitive models of human information processing. Essential to the consideration of possible variables to be controlled when designing experimental work on cognitively related issues are variables such as the subjects' age, sex, or education. Barely a handful of studies have ever taken eye colour seriously as a variable to be controlled when exploring cognitively related issues. Very few researchers have considered the possibility that a person's eye colour might influence reaction time. The question is whether eye colour should be taken seriously when designing experimental work in cognitive psychology. In this study we found significant differences in choice reaction time using the McCarthy and Donchin (1981) paradigm, the dark-eyed subjects being faster tha the light-eyed. Implications of the findings are discussed.
基于反应时间进行分析的证据推动了人类信息处理认知模型的发展。在设计与认知相关问题的实验工作时，需要考虑的可能要控制的变量中，诸如受试者的年龄、性别或教育程度等变量至关重要。在探索与认知相关问题时，几乎没有几项研究曾认真将眼睛颜色作为一个要控制的变量。很少有研究者考虑过人的眼睛颜色可能会影响反应时间这种可能性。问题在于，在认知心理学实验工作设计中是否应该认真对待眼睛颜色。在本研究中，我们使用麦卡锡和唐钦（1981年）的范式发现，在选择反应时间上存在显著差异，深色眼睛的受试者比浅色眼睛的受试者反应更快。我们将讨论这些研究结果的意义。
