2. Ivan Pavlov—Russian scientist trained in biology and medicine Studied digestive system in dogs Operant Conditioning The study of the impact of consequences on voluntary behavior. The addition and/or subtraction of consequences is done according to different schedules Continuous Intermittent The study of the impact of consequences on voluntary behavior. The addition and/or subtraction of consequences is done according to different schedules Continuous Intermittent

3. Continuous reinforcement – the target behavior is followed by a consequence each time it occurs. Excellent for getting new behavior started that you want to increase. Behavior stops quickly when reinforcement stops. Continuous reinforcement – the target behavior is followed by a consequence each time it occurs. Excellent for getting new behavior started that you want to increase. Behavior stops quickly when reinforcement stops. Schedules of Consequences The schedule of choice for decreasing behavior.

4. Intermittent schedules based on either Passage of time OR Number of correct responses Intermittent schedules based on either Passage of time OR Number of correct responses Schedules of Consequences

5. Consequence can be delivered based on A fixed amount of time or number of correct responses OR A slightly different amount of time or number of correct responses that vary around a particular number Consequence can be delivered based on A fixed amount of time or number of correct responses OR A slightly different amount of time or number of correct responses that vary around a particular number Schedules of Consequences

6. This results in four classes of intermittent schedules. Fixed Interval consequence is given or removed when the first target response is emitted after a set amount of time has passed. The time period required is always the same. Example: Spelling test every Friday. This results in four classes of intermittent schedules. Fixed Interval consequence is given or removed when the first target response is emitted after a set amount of time has passed. The time period required is always the same. Example: Spelling test every Friday. Schedules of Consequences

7. Pattern of behavior for fixed interval schedule

8. This results in four classes of intermittent schedules. Variable Interval Consequence is given or removed when the first target response is emitted after a set amount of time has passed. A time period is then set with the average equaling a specific number. Example: Pop quiz. This results in four classes of intermittent schedules. Variable Interval Consequence is given or removed when the first target response is emitted after a set amount of time has passed. A time period is then set with the average equaling a specific number. Example: Pop quiz. Schedules of Consequences

9. Pattern of behavior for variable interval schedule

10. This results in four classes of intermittent schedules. Fixed Ratio Consequence is given or removed when a specified number of target responses have been emitted. A number of required target behaviors stays the same. Example: 10 math problems for homework. This results in four classes of intermittent schedules. Fixed Ratio Consequence is given or removed when a specified number of target responses have been emitted. A number of required target behaviors stays the same. Example: 10 math problems for homework. Schedules of Consequences

11. Pattern of behavior for fixed interval schedule

12. This results in four classes of intermittent schedules. Variable Ratio Consequence is given or removed when a specified number of target responses have been emitted. The number of required target behaviors changes around an average. Example: students raises hand to be called upon. This results in four classes of intermittent schedules. Variable Ratio Consequence is given or removed when a specified number of target responses have been emitted. The number of required target behaviors changes around an average. Example: students raises hand to be called upon. Schedules of Consequences
