Two observers performed simple reaction-time responses to peripheral stimuli of varying intensity (-2.5 to +1.0 log td) and angular subtense (10 to 210 min). The area-intensity combinations that produced each of three scotopic reaction-time criteria were calculated. Analysis of these combinations showed that the area-intensity reciprocity could not be predicted by traditional theories of spatial summation. Like earlier findings for peripheral photopic reaction-time criteria, the results indicated that for small stimulus sizes, area has a greater effect than intensity in determining the scotopic reaction-time responses.
两名观察者对不同强度（-2.5至+1.0对数td）和视角（10至210分）的外周刺激进行简单反应时响应。计算出产生三种暗视反应时标准中每一种的面积-强度组合。对这些组合的分析表明，传统的空间总和理论无法预测面积-强度互易性。与早期关于外周明视反应时标准的研究结果一样，结果表明，对于小刺激尺寸，在确定暗视反应时响应方面，面积比强度的影响更大。
