    Author: Varga ME.
    Journal: Zh Vyssh Nerv Deiat Im I P Pavlova; 1996; 46(4):732-9. PubMed ID: 8984811.
    Abstract:
    Food instrumental asymmetrical differentiation (discrimination) between the reinforced train of five identical clicks administered with variable interstimulus intervals and the non-reinforced train of the same three clicks was elaborated in six dogs. At the stable stage of conditioning, the number of instrumental reactions to five clicks was twice higher than to three clicks. Temporal parameters of such kind of counting reactions are analyzed. A conclusion is made that dogs, can discriminate the number of identical signals in the consecutive train and use this parameter in their adaptive behaviour. Types of the internal inhibition which participate in the above-described differentiation are considered.
