采用双目匹配法对人体进行同步亮度感应测量。在观测者的右眼上呈现出一个均匀照射的圆盘形试验场和一个完全包围试验场的环形诱导场。在观察者的左眼上呈现一个与测试场大小和形状相同的比较场。观测者在测试场和比较场之间进行亮度匹配。以对比场的匹配亮度作为测试场视亮度的指标，研究了诱导场的亮度变化对测试场视亮度的影响。诱导亮度从与测试场几乎相同到大于测试场的场会降低测试场的视亮度。讨论了对这些结果可能的理论解释以及这些数据在亮度常数分析中的应用。
Simultaneous brightness induction was measured in human subjects by means of a binocular matching method. The test field, an evenly illuminated disc-shaped area, and an annular inducing field which completely surrounded the test field, were presented to the observer''s right eye. A comparison field of the same size and shape as the test field was presented to the observer''s left eye. The observer made brightness matches between the test and comparison fields. With the matched luminance of the comparison field serving as an indicant of the apparent brightness of the test field, the effect of varying the luminance of the inducing field on the apparent brightness of the test field was studied for several luminance levels of the test field. Inducing fields with luminances from almost as great to greater than that of the test field depressed the apparent brightness of the test field. Possible theoretical interpretations of the results and the application of the data to the analysis of brightness constancy are discussed.
