Licking behavior of rats on a schedule of food reinforcement.
Rats were trained on a variable-interval food reinforcement schedule. Lever presses and licks at the milk reinforcement were recorded independently. A dose of d-amphetamine which increased lever-pressing rates failed to affect licking rates. Licking rates increased as the duration between reinforcements on the variable-interval schedule increased.
