Summary

Here's what we concluded about schedules of reinforcement:

1. Fixed-ratio schedules and variable-ratio schedules produce high rates of responding. These schedules are used when we want the behavior to occur often.

2. Fixed-interval schedules produce a clustering of responses around reward time. This schedule is used when we want the behavior to occur at specified times but not constantly.

3. Variable-interval schedules produce low but fairly constant rates of responding. This schedule is used when we want the behavior to occur on an ongoing basis, but not too frequently.
