Document Summary

The four simple reinforcement schedules fixed ratio schedule (fr): a reinforcer is delivered after every n responses, where n is the ratio example: fr 20 schedule- every 20 responses will be followed by a reinforcer. Fr1 schedule is the same as continuous reinforcement. After each reinforcer, there is a pause in responding which is called the post- reinforcement pause. Once the responding begins, the subject typically responds at a constant, rapid rate until the next reinforcer is delivered. The average size of the post-reinforcement pause increases as the size of reinforcement increases. The subject"s rate of responding after the post-reinforcement pause decreases fairly gradually as the size of the ratio increases ratio strain: the general weakening of responding that is found when large response: reinforcer ratios are used. Variable ratio (vr): on average a subject will receive one reinforcers for every n responses, but the exact number if responses required at any moment may vary widely.
