Behavior refers to the way someone conducts themselves including their actions, reactions, and functioning in response to everyday environments and situations.
- Behaviors that are expected and approved: This might include doing homework regularly, being polite, and doing chores without any hustle. Their actions receive compliments freely and easily.
- Behaviors that are unsanctioned but are tolerated under certain circumstances: During times of illness (of a parent or a child) or stress (a change of house or school, or the birth of a new sibling). These kinds of behavior might include not doing chores, regressive behavior, or being excessively self-centered.
- Behaviors that cannot and should not be tolerated or reinforced: This includes actions that are harmful to the physical, emotional, or social well-being of the child, the family members, and others. This behavior might interfere with the child's intellectual development or may be forbidden by law, ethics, religion, or social mores. It might include very aggressive or destructive behavior, overt racism or prejudice, stealing, truancy, smoking or substance abuse, school failure, or an intense sibling rivalry.
