title: [Psychophysiological signs of high-flexible forms of set on the emotionally negative facial expression].
abstract: In a series of studies of influence of past experience on an recognition of emotionally negative facial expression where obtained experimental facts which we consider as the formation signs of under certain conditions high-plastic cognitive (flexible) sets ("not fixed sets", according to D.N. Uznadze) when there switching or updating was not accompanied by illusory distortion of recognition. The studies of this form of set revealed: 1--the induced reaction of synchronization of a teta-rhythm to target stimulus was larger, than in cases with rigid set; 2--the induced reaction of an alpha rhythm to target stimulus is expressed in its synchronization, at the others cases--in a desynchronization; 3--at increase in a time interval between target and trigger stimuli observe alpha rhythm synchronization in the prestimulus period and in time intervals between them, at other cases it wasn't observed; 4--at children this form of set observed at the age of 10-11 years when "mature" set on an facial expression is formed.
