Definition
Intermittent Reinforcement refers to reinforcement schedules in which a response is only reinforced some of the time, rather than after every single response. This method of reinforcement is used to maintain behaviors over time and can make the behavior more resistant to extinction.
Example
In a classroom setting, a teacher might praise a student for correctly answering a question only occasionally, rather than after every correct response. This encourages the student to continue performing well, even without constant reinforcement.
