Adjunctive drinking during variable and random-interval food reinforcement schedules.

Аннотация
In 2 experiments, a total of 12 male albino rats were trained to leverpress for food and subsequently exposed to either arithmetic series or random VI reinforcement schedules. Adjunctive drinking developed in all Ss exposed to arithmetic VI reinforcement but did not develop in 6 of the 8 Ss trained on the random schedule. Results suggest that adjunctive drinking is the result of an interaction between the tendency of rats to drink after eating and the ability of locally low probabilities of reinforcement within schedules to induce conditioned behavioral states.
