It has been said time and time again that teenagers are, by nature, defiant in their behavior. New parents think nervously about the day their little ones will reach the teenage stage. Often, however, defiant behavior in teenagers is caused by outside influences, rather than biology. Peer influence, drugs, depression, social disorders, and other pressures can affect teen behavior.

Social Learning

Behavior is learned by imitating others and is strengthened through rewards and punishments, according to a study conducted by Ronald L Akers and associates at the University of Iowa. “In addition, people learn in interaction with significant groups in their lives evaluative definitions -- norms, attitudes, orientations -- of the behavior as good or bad.” In other words, a deviant teen may be acting poorly because:

  • his peer group evaluates bad behavior as “cool” or “normal”
  • rewards it while punishing good behavior
