[Temporal connections in the performance by children of choice-by-model reactions].
Mechanisms of choice reactions by model were studied in children 3-6 years old, when the relevant figure coincided with the model by the meaning of only one of three properties, and irrelevant one--by meanings of two noncriterial properties, and differed from the model by the meaning of the criterial property. Criterial properties in various series were colour, form and size. Two propositions are substantiated: 1) the reaction presents a fine differentiation, the signal of which is the coincidence of excitations only in one of several channels of processing of information on objects physical properties; 2) alongside with positive temporary connection to excitations coincidence, in the given conditions a second inhibitory temporary connection is formed which leads to refusal from the irrelevant figure choice. Its signal is noncoincidence of excitations in the criterial channel of processing of information on objects physical properties. This second inhibitory connection is weak in 3-4 years old children and becomes stronger with age. A conclusion is made about acceptability and sufficiency of principles of temporary connection and systematization for physiological analysis of intellectual behavioural acts.
