托福口语 Task 3

Behavioral momentum refers to the tendency of a behavior to persist despite changes in the environment or interruptions. In psychology, this concept suggests that behaviors reinforced over a long period with high frequency are more resistant to extinction or disruption. Essentially, the stronger the reinforcement history, the greater the momentum, making the behavior less likely to stop when faced with challenges or altered conditions.

Professor: Let me give you an example from a study on classroom habits. Imagine a teacher who rewards students with stickers every time they raise their hands to answer questions. This happens consistently for months, so the behavior becomes deeply ingrained. One day, the teacher stops giving stickers, but the students continue to raise their hands for a while. In another class, the teacher only gave stickers occasionally and randomly, so when the stickers stopped, the students quickly stopped raising their hands. The first class showed higher behavioral momentum because the reinforcement was consistent and frequent, making the behavior more resistant to the change. This illustrates how past reinforcement patterns can predict persistence.
