In positive reinforcement, what is the relevant change introduced to influence behavior?

1. Aversive stimulus

2. Rewarding stimulus

3. Neutral stimulus

4. Conditioned stimulus

The correct answer is: Rewarding stimulus

In positive reinforcement, the relevant change introduced to influence behavior is a rewarding stimulus. Positive reinforcement involves adding a stimulus that the individual finds pleasurable or desirable immediately following a desired behavior. This addition increases the likelihood that the behavior will be repeated in the future. For instance, if a child completes their homework and then receives praise or a treat, that positive feedback encourages them to continue completing their homework in anticipation of similar rewards. This concept is fundamental in behavior modification and helps in establishing and maintaining desired behaviors effectively. Other stimuli, such as aversive or neutral stimuli, do not promote the desired behavior in the same way as rewarding stimuli do. Averse stimuli typically discourage behavior rather than encourage it, while neutral stimuli do not have a significant impact on the behavior being reinforced. Conditioned stimuli could play a role in behavior through their association with other reinforcing or punishing outcomes, but they do not directly provide the reward necessary for positive reinforcement.
