| Fixed ratio schedules | reinforcement occurs after a set number of responses |
| Fixed interval schedules | reinforcement occurs after a set length of time |
| Variable ratio schedules | reinforcement occurs after an unpredictable number of responses |
| Variable interval schedules | reinforcement occurs after an unpredictable length of time |
