[The dependence of the dynamics of the extinction of a temporary connection on the recognizability of a reinforcing stimulus].
Dynamics was studied of the extinction of temporary connection, elaborated by means of motivationally significant word, in patients with chronic alcoholism. Two series of studies were conducted. In the first one the reinforcing stimulus was not recognized by the subject and was perceived as a dull light flash on the screen. In the second one the word was easily read, i.e. it was recognized. It was found that conditioned changes of P300 wave at the elaboration of temporary connection depend on the recognition of the reinforcing stimulus. Temporary connections, elaborated by non-recognized motivationally significant stimulus are considerably stronger that the connections, elaborated by means of recognized reinforcement.
