[Searching activity under different reinforcement regimens and the process of information interaction with the...

When training rats in casual environmental conditions the search activity is determined by the regimen of unconditioned confirmation and the probability of a primary chance correct performance of instrumental reactions (PCCR). The value of PCCR determines what part of instrumental reactions will be realized due to a conditioned signal and confirmed appropriately. This, in its turn, influences the informational interaction of the animal with the environment in any regimen of confirmation (constant or probable). With the least favourable values of PCCR for learning a decreased number of confirmation lowers the search activity due to a sharp deterioration of the conditions for acquiring information--both factors (PCCR and low frequency of confirmation) cause single-directed changes (decrease) in informational significance of research reactions. The optimal PCCR values for learning promote informational significance of every search reaction, this leading to, weakening of the relationship between the intensity of the search activity and probability of unconditioned confirmation.
