在一个6°环围的30′测试场上，测量了不同对比度下的亮度匹配和对正弦闪烁的灵敏度。使用产生10 000-、3000-、1000-、300-、100-和30-td视网膜照度的测试场。当环境亮度从零开始增加时，测试场的匹配亮度保持不变，当环境亮度为测试场亮度的十分之一时，匹配亮度迅速下降。闪烁敏感度遵循不同的函数：当周围环境的亮度为测试场亮度的百分之一时，闪烁敏感度开始增加，在三分之一时达到峰值，然后迅速下降。灵敏度的提高与闪烁频率无关。结果归因于视觉系统中的空间相互作用。
Both brightness matching and sensitivity to sinusoidal flicker were measured for different contrasts using a 30′ test field surrounded by a 6° annulus. Test fields that produced 10 000-, 3000-, 1000-, 300-, 100-, and 30-td retinal illuminance were used. Matched brightness of the test field remained constant as surround luminance was increased from zero, then fell rapidly when the luminance of the surround was one tenth that of the test field. Flicker sensitivity followed a different function: It began to increase when the surround had one hundredth the luminance of the test field, reached a peak at one third, and then fell rapidly. The sensitivity enhancement was independent of flicker frequency. The results are attributed to spatial interactions in the visual system.
