Effects of fixed-interval schedule and reinforcer duration on responding reinforced by the opportunity to run

Article Abstract:

An experiment was conducted to determine the effects of reinforcer duration and schedule value on the running and opportunity-to-run response of rats on standard fixed-interval (FI) schedules. Postreinforcement pauses (PRP) were often longer than the FI indicating that such pauses may be due to the satiation aftereffects of running rather than temporal control by FI schedule. It was found that increasing reinforcement magnitude would increase PRP duration. However, it was not established that increasing FI schedule values would increase PRP duration.

Response-independent milk delivery enhances persistence of pellet-reinforced lever pressing by rats

Article Abstract:

Experiments with rats have suggested response-independent reinforcers need not be the same as response-dependent reinforcers to enhance persistence. Conditioned lever-pressing resisted extinction during stimulus when the stimulus volume was increased and blackout periods became longer.

Studies of wheel-running reinforcement: parameters of Herrnstein's (1970) response-strength equation vary with schedule order

Article Abstract:

Reinforcement and response rates were measured in rats in order to examine Herrnstein's (1970) single-operant matching law. Varied wheel-running reinforcement schedules were applied to rats to analyze the response-reinforcer relation.
