[The generalization of speech reactions to various instructions].

It is found that there is a direct correspondence between similarity meaning degree of sentences and quantity of positive reactions irrespective of the preliminary instructions. All this permits to estimate quantitatively the conditional reflex activity of sentence.

[Participation of the orienting-exploratory reaction in the formation of a secondary signal association system in lecture instruction].

The close correlation between the skin galvanic reaction (SGR) and the process of formation of scientific knowledge (abstract-logical temporal connections) has been shown by using SGR for the determination of the secondary signal system activity. Rather a high level of each student's SGR is kept during the whole lecture. The more active the student's SGR is mobilized the more efficient the scientific knowledge is learnt.
