Abstract

In two experiments, simple reaction time to left-field or right-field stimulation was measured as a function of light intensity. The response made on each trial in Experiment 1 was a finger movement, and in Experiment 2 a spoken word. In Experiment 1, the advantage of "uncrossed" over "crossed" reaction times remained invariant across intensities. In Experiment 2, however, the advantage of right over left visual-field stimuli in eliciting a vocal reaction varied inversely with intensity. It is suggested that the use of vocal reactions may permit an estimation of a visual commissural transmission time.

摘要

在两项实验中，测量了对左视野或右视野刺激的简单反应时间，并将其作为光强度的函数。实验1中每次试验的反应是手指移动，实验2中则是说出一个单词。在实验1中，“非交叉”反应时间相对于“交叉”反应时间的优势在不同强度下保持不变。然而，在实验2中，右视野刺激相对于左视野刺激在引发语音反应方面的优势随强度呈反比变化。有人认为，使用语音反应可能有助于估计视觉连合传递时间。
