[Stimulus recognition as a factor in establishing the effective properties of the signal]

Abstract

An attempt was made to estimate the importance of preliminary perceptual learning of the recognition of indifferent stimulus for the formation of effective properties of the trigger signal of conditioned reflex functional system. The dynamics of the elaboration of instrumental conditioned reflexes was compared: 1) when an unfamiliar signal was introduced into the experimental environment (control experiments). 2) in case of introduction of a perceptually familiar signal, 3) after "erasing" of acquired perceptual experience by electroshock. The experiments revealed that a preliminary perceptual learning contributes to the formation of the effective properties of the trigger signal.
