Operant Conditioning:Operant conditioning is a learning process in which repeated behaviors are strengthened or weakened by consequences. Aggressive behavior may be reinforced if it leads to desired outcomes or punished if it results in negative consequences.
Social Learning Theory:Social learning theory explains how individuals learn through observing and imitating others' behaviors. A teenager may engage in repeated aggressive behavior after witnessing aggression from peers, family members, or media influences.
Frustration-Aggression Hypothesis:The frustration-aggression hypothesis suggests that aggression can arise from feelings of frustration when one's goals are blocked or unfulfilled. In the case of repeated aggressive behavior, a teenager might resort to aggression as a response to persisting frustrations.
