What is the defining characteristic of intermittent reinforcement?

1. All behaviors are reinforced consistently

2. Some but not all behaviors are reinforced

3. Reinforcement is never provided

4. All reinforcement is withheld

The correct answer is: Some but not all behaviors are reinforced

The defining characteristic of intermittent reinforcement is that some but not all behaviors are reinforced. This means that reinforcement is delivered on a variable schedule rather than every time the desired behavior occurs. This method can lead to stronger and more resilient behavior patterns because the unpredictability keeps the individual engaged and motivated, as they continue to perform the behavior in hopes of receiving the reinforcement. This type of reinforcement can strengthen the behavior over time, as individuals often persist in the behavior even when reinforcement is not always provided. In contrast, when all behaviors are reinforced consistently, a fixed reinforcement schedule is in play, which can lead to faster extinction of the behavior when reinforcement is no longer available. If reinforcement is never provided, behaviors are unlikely to be established or maintained. Similarly, withholding all reinforcement can lead to a complete lack of motivation to engage in the behavior. Thus, intermittent reinforcement’s key aspect is its selective reinforcement of behaviors, leading to more durable learning and behavior maintenance.
