Lesson Transcript
Instructor: Yolanda Williams

Aggressive behaviors are those that are hostile and violate other people's rights. Learn about reactive and proactive aggressive behaviors, the mental disorders associated with aggressive behavior, and more, in this lesson.

What is Aggressive Behavior?

Sarah and Misha are two friends playing in the backyard. Sarah reaches over and grabs one of Misha's toys without asking, which upsets Misha. This is not the first time that Sarah has taken one of Misha's toys without permission, which angers Misha even more. Misha walks up to Sarah, pushes Sarah, and takes back her toy. By pushing Sarah, Misha has demonstrated one type of aggressive behavior.

Aggressive behavior is a type of behavior where people attempt to stand up for themselves or exert power over others in ways that are hostile and violate the rights of others. People who are on the receiving end of aggressive behavior, such as Sarah, usually feel dominated, embarrassed, guilty, or shamed as a result of a situation. Aggressive behaviors differ from passive aggressive behaviors, which seek to disguise feelings of anger in that they:

  • Are usually intentional and meant to harm someone, either psychologically or physically, or destroy someone's belongings
  • Can be directed toward another person or the self, such as a teenager who likes to injure herself by cutting her wrists
  • Are a major violation of the norms or rules of a particular society
  • Can cause major impairments to academic, social, or workplace life

For example, can you imagine working with a co-worker who liked to break other people's property every time he or she became upset or stressed? Or, being friends with someone who attempts to control you with physical violence or threats?

Types of Aggressive Behaviors

Aggressive behaviors can be reactive or proactive. Reactive aggressive behaviors are unplanned and impulsive, and are usually a response to feelings of anger, fear, or a need to retaliate against someone. When Misha pushes Sarah she's demonstrating reactive behavior. By comparison, proactive aggressive behaviors are calculated and planned actions that have some motive other than harming someone.

Bullying is a form of proactive aggressive behavior. For instance, suppose that Mike is a seventh grade boy who bullies the other children in his class. Mike's bullying may be motivated by his need to feel superior to his classmates. Furthermore, Mike's bullying behaviors are preplanned. He knows exactly whom he is going to bully and when.

Examples of aggressive behaviors include:

  • Physical violence, such as biting, hitting, and kicking
  • Verbal hostility, like sending threatening messages through emails, phone calls, or social media, or making threats against someone's life, shouting, and swearing
  • Nonverbal intimidation, such as making threatening gestures, sending unwanted gifts, and sexual harassment
  • Destruction of property, like breaking someone's computer, destroying someone's cell phone, or other forms of vandalism.
