Which of the following best describes positive reinforcement?

• A. Removing an aversive stimulus
• B. Adding a desirable stimulus to increase behavior
• C. Reducing a behavior through punishment
• D. Ignoring inappropriate behavior

Answer: (B)

Positive reinforcement is best described as the process of adding a desirable stimulus to increase the likelihood of a behavior being repeated in the future. This is a key concept in behavior analysis, where the focus is on how certain consequences or stimuli can influence behavior. When a behavior is followed by something that the individual finds rewarding, it increases the chances that this behavior will occur again.

For example, if a teacher praises a student for completing their homework, the praise acts as a positive reinforcer, encouraging the student to continue completing their homework in the future. This concept is fundamental in both educational settings and therapy, as it helps individuals learn desirable behaviors by effectively using incentives.

In contrast, other options do not align with the concept of positive reinforcement. One speaks about removing an aversive stimulus, which describes negative reinforcement, while others refer to punishment and ignoring behavior, neither of which aims to increase a behavior through the addition of a positive stimulus.
