When Ss in previous research were tested on a color-word interference task, the stimuli were generally said to have been presented in a well-lighted room, or with adequate lighting, or with a good light source, and the like. The present research attempted to find out the difference in performance between (a) Ss performing the task under a level of illumination of 5 ft-c, (b) Ss performing the task under a level of illumination of 150 ft-c, and (c) a control group performing the same task under a level of illumination of 50 ft-c. Results indicated that the Ss of both the 5 and 150 ft-c groups took significantly longer and made significantly more errors than the control group. It was concluded that levels of illumination under which the color-word interference task is performed significantly affect performance.
在以往的研究中，当对被试进行颜色-文字干扰任务测试时，刺激物通常被描述为是在光线充足的房间里呈现的，或者有足够的照明，或者有良好的光源等等。本研究试图找出以下三者之间在表现上的差异：(a) 在5英尺烛光照明水平下执行任务的被试；(b) 在150英尺烛光照明水平下执行任务的被试；(c) 在50英尺烛光照明水平下执行相同任务的对照组。结果表明，5英尺烛光组和150英尺烛光组的被试比对照组花费的时间显著更长，并且犯的错误显著更多。得出的结论是，执行颜色-文字干扰任务时的照明水平会显著影响表现。
