The phenomena observed during book retinoscopy include changes in the brightness of the reflex in response to changes in cognition. This experiment shows that the increase in luminance of the relfex that results from increased cognitive demand is mediated by accommodation. The luminance of the fundus reflex was monitored while subjects either read or added a series of two-digit numbers. During the addition task the luminance of the reflex increased in all cases. However, under cycloplegia the increase in luminance could not be predicted.
在检眼镜视网膜检影期间观察到的现象包括反射亮度随认知变化而改变。该实验表明，因认知需求增加而导致的反射亮度增加是由调节介导的。在受试者阅读或相加一系列两位数时，监测眼底反射的亮度。在加法任务期间，所有情况下反射亮度均增加。然而，在睫状肌麻痹状态下，亮度增加无法预测。
