What is a potential drawback of using fixed schedules for reinforcement?

Using fixed schedules for reinforcement can indeed present drawbacks, particularly in terms of maintaining established behaviors. A fixed schedule provides reinforcement at regular, predictable intervals after a specific number of responses or after a set amount of time has passed. This predictability can lead to certain limitations.

For instance, while fixed schedules can initially establish a behavior, they can also cause individuals to become less responsive once the behavior is learned. Once the scheduled reinforcement becomes predictable, the individual may not sustain the behavior as consistently compared to variable schedules, where reinforcement is less predictable and can encourage continuous engagement. Fixed schedules may lead to a decrease in motivation to perform the behavior once the reinforcement is expected, making it less effective for maintaining the behavior over time.

Consequently, fixed schedules might result in patterns of responding that are too intermittent and can even lead to frustration or disinterest from the learner when the reinforcement does not match their effort continuously. In summary, while they may effectively initiate learning, fixed schedules can struggle with retention and maintenance of behaviors in the long run.
