This study considered whether the dynamics of flicker adaptation can be explained in terms of probability summation over time between independent ON- and OFF-processors. Foveal thresholds were measured for flickering probes, and for static ON- and OFF-probes that have durations consistent with the flicker duty cycle. Thresholds were obtained using a probe-flash stimulus onset asynchrony paradigm. The outcome of the experiment suggests that flicker thresholds are lower than the component ON- and OFF-thresholds, and that the flicker response can be predicted by assuming probability summation between the ON- and OFF-mechanisms.
本研究探讨了闪烁适应的动力学是否可以通过独立的开（ON）和关（OFF）处理器随时间的概率总和来解释。测量了中央凹对闪烁探针以及持续时间与闪烁占空比一致的静态开和关探针的阈值。使用探针闪光刺激起始异步范式获得阈值。实验结果表明，闪烁阈值低于开和关成分的阈值，并且可以通过假设开和关机制之间的概率总和来预测闪烁反应。
