Berkowitz's Frustration-Aggression Hypothesis suggests that frustration, which occurs when a person is blocked from achieving a goal, can lead to aggressive behavior. This theory posits that when individuals experience frustration, they may respond with anger and aggression, especially if they perceive the source of their frustration as intentional. The hypothesis also emphasizes that aggression can be influenced by environmental cues, such as the presence of weapons or aggressive stimuli. According to this theory, these cues can trigger aggressive responses, making it more likely for frustrated individuals to act out violently in certain situations.
