[Dynamics of visual association formation in man].
The subjects were asked to memorize four combinations of paired visual stimuli on an illuminated tableau. The test-signal, a single flash on the tableau, was presented after the signal pair and could coincide either with the second component of the association or with the elements not involved in this particular association. After presentation of the test signal, the subject had to press the key as quickly as possible and then point to the pair on the tableau, associated with the signal pair (the second component of the association). The changes occuring in the structure of the association were evaluated by the changes of reaction time (rt) to the test-signal and the RT variability. Differences have been revealed between the RT dynamics and variabilities, which characterize the functional state of the elements activated during the achievement of the association and those not participating in the given association. During stabilization of the visual association, oppositely directed tendencies of RT changes and variabilities were observed.
