Which defining characteristic describes aggressive behavior?

The defining characteristic of aggressive behavior is illustrated by the readiness to attack or start fights while acting in a hostile manner. This type of behavior typically involves overt expressions of anger or dominance, and it may manifest through verbal or physical actions that threaten or harm others. Individuals displaying aggressive behavior often prioritize their own needs or desires over those of others, which can lead to conflict and discomfort in social interactions.

In contrast, a calm and cooperative demeanor reflects a collaborative approach, which is not aligned with aggression. Submissive and yielding behaviors suggest a lack of assertiveness, indicating a tendency to give in to others rather than confront them. Lastly, being confident in expressing ideas and thoughts is associated with assertiveness, which differs from aggression in that it respects both one's own position and those of others, fostering constructive dialogue rather than hostility. Thus, the second choice accurately captures the essence of aggressive behavior.
