EEG and behavioural reactions were studied at the action of signal and nonsignal light flashes. The minimal time of stimulus exposition necessary for preserving differences in EEG activation reactions to nonreinforced stimuli of different intensity (in a diapason from 3.5 to 250 lk) was shown to exceed 1 s. After giving the signal meaning to the flashes the minimal time of stimulus exposition when the animals were capable to discriminate intensity of the flashes (in a diapason from 3.5 to 30 lk) just at the first presentation, was equal to 0.1 s. Decrease of the minimal time of stimulus exposition necessary for discrimination of the light signals was supposed to be stipulated by their biological significance and presetting of the analyzing system being organized by preliminary learning a crude analysis of stimuli. Discrimination of the light stimuli of short duration was impossible without such presetting.
在信号和非信号光闪烁作用下研究了脑电图（EEG）和行为反应。结果表明，要保持对不同强度（范围为3.5至250勒克斯）非强化刺激的EEG激活反应差异，刺激呈现的最短时间超过1秒。在赋予闪光信号意义后，动物能够在首次呈现时辨别闪光强度（范围为3.5至30勒克斯）的刺激呈现最短时间为0.1秒。光信号辨别所需的刺激呈现最短时间的缩短被认为是由其生物学意义以及通过对刺激进行初步粗略分析的预先学习所构建的分析系统的预设所规定的。没有这种预设，就不可能辨别短持续时间的光刺激。
