INTERRESPONSE‐TIME SHAPING BY VARIABLE‐INTERVAL‐LIKE INTERRESPONSE‐TIME REINFORCEMENT CONTINGENCIES1

The interresponse-time reinforcement contingencies and distributions of interreinforcement intervals characteristic of certain variable-interval schedules were mimicked by reinforcing each key peck with a probability equal to the duration of the interresponse time it terminated, divided by the scheduled mean interreinforcement interval. The interresponse-time reinforcement contingency was then eliminated by basing the probability of …
