When individuals with challenging behaviors are placed in a group with people without challenging behaviors, the behavior often improves because the individuals:

The correct answer highlights a key aspect of social learning theory, which suggests that individuals often adopt behaviors they observe in others, particularly in a peer setting. When individuals with challenging behaviors are placed in a group with peers who demonstrate appropriate behaviors, they have the opportunity to observe and imitate these positive behaviors. This observational learning can lead to improved social skills and behavioral adjustments over time, as they begin to understand what is acceptable in a social context.

Peer influence is a powerful tool in shaping behavior; being around individuals who model constructive interpersonal skills can encourage those with challenging behaviors to adapt and modify their own actions. This dynamic fosters an environment where positive behaviors are not just encouraged but are also reinforced by the group.

In contrast, the other choices do not effectively explain why behavior might improve in this context. Merely receiving more medication does not inherently lead to behavioral improvement if the understanding and practice of appropriate behaviors are absent. While better supervision can help manage behaviors to some extent, it does not provide the same learning opportunity that peer interactions do. Similarly, the assertion that individuals no longer need to communicate their feelings or needs overlooks the fundamental human drive for connection and expression, which is essential for personal development and behavioral change.
