Which reinforcement schedule is known for being more resistant to extinction?

The variable ratio reinforcement schedule is recognized for its high resistance to extinction because it delivers rewards after an unpredictable number of responses. This unpredictability keeps the individual engaged because they never know when the next reward will come. As a result, a person is likely to continue the behavior longer, maintaining their effort even when rewards are not immediately forthcoming. This makes it particularly effective in promoting persistent behavior over time.

In contrast, fixed interval and fixed ratio schedules provide rewards based on a set time or number of responses, which can lead to predictable patterns of behavior – and when rewards are no longer provided, individuals may cease the behavior more quickly. Similarly, variable interval schedules, while more resistant than fixed schedules, do not have the same level of engagement as variable ratio schedules, which often create a strong and persistent drive for the individual to continue responding.
