A comparison of variable-ratio and variable-interval schedules of reinforcement.

abstract：:If a response key is regularly illuminated for several seconds before food is presented, pigeons will peck it after a moderate number of pairings; this "auto-shaping" procedure of Brown and Jenkins (1968) was explored further in the present series of four experiments. The first showed that pecking was maintained even ...

abstract：:The ability of organisms to detect reinforcer-rate changes in choice preparations is positively related to two factors: the magnitude of the change in rate and the frequency with which rates change. Gallistel (2012) suggested similar rate-detection processes are responsible for decreases in responding during operant e...

abstract：:In a two-key concurrent variable-interval schedule (using pigeons), if the reinforcement frequency for one response is held constant while that for the other is increased, the rate of response on the constant key decreases. The immediate reinforcement for key pecking can usually be conceptualized as the change from a ...
