In Behavior Modification, what is the effect of reinforcements?

• A. They can permanently fix behavior
• B. Behavior cannot be changed
• C. They always increase anxiety
• D. Reinforcements, either positive or negative, can alter the behavior.

Answer: (D)

The key idea is that reinforcement changes how often a behavior occurs by following it with a consequence. Positive reinforcement adds something desirable after the behavior, making it more likely to happen again. Negative reinforcement takes away an unpleasant stimulus after the behavior, also increasing its likelihood in the future. Together, these reinforcements shape behavior by increasing its frequency or strength, rather than providing a permanent fixed outcome or causing anxiety as a general rule.

Reinforcement isn’t a guarantee of permanent change; if reinforcement ends, the behavior may fade or require maintenance through ongoing reinforcement or additional strategies. It also doesn’t inherently raise anxiety—negative reinforcement reduces an aversive condition by removing it after the desired behavior occurs, and reinforcement overall is about changing likelihood, not creating fear.
