Which of the following statements about reinforcement schedules is true?

The statement that gradually thinning a schedule can maintain learner engagement is accurate and reflects a fundamental principle in behavior psychology. Thinning a reinforcement schedule refers to the process of gradually decreasing the frequency with which reinforcement is provided after a desired behavior occurs. This approach helps to encourage sustained engagement and encourages the learner to continue performing the behavior even when reinforcements become less frequent.

When a learner is accustomed to frequent reinforcement, they may become dependent on it; reducing the frequency of reinforcement can lead to a more robust and self-sustaining behavior pattern. For instance, if a student receives praise for correct answers every time they respond correctly but then starts receiving praise intermittently or less frequently, they may maintain their motivation and engagement better in the long term. This strategy can help learners to commit the behavior to memory and develop intrinsic motivation.

Options that suggest keeping reinforcement schedules constant, increasing reinforcement quickly, or stating that interval schedules do not need adjustment lack the understanding of behavioral dynamics, as these can lead to decreased motivation or even desensitization to the reinforcements. In contrast, a well-designed and gradually adjusted reinforcement schedule fosters ongoing learner engagement and promotes lasting learning outcomes.
