Which of the following behaviors is NOT a sign of changes in social interaction?

Frequent and positive communication is indicative of healthy social interaction and is typically a sign of well-being and positive mental health. When individuals engage in frequent and positive communication, they are actively participating in social interactions, building relationships, and displaying an ability to connect with others.

In contrast, the other behaviors listed suggest a decline or change in social interaction. Avoiding social contact may indicate social withdrawal or difficulty in social situations, while fighting verbally or physically suggests conflict and distress in interactions. Bragging frequently can be a sign of insecurity or a need for validation, which often impacts social dynamics negatively. Therefore, frequent and positive communication stands out as a behavior that does not signify a change in social interaction.
