Aggression theories explore the reasons behind aggressive behavior in humans and animals. One prominent theory is the frustration-aggression hypothesis, which suggests that aggression is a response to frustration when individuals are blocked from achieving their goals. This theory emphasizes the connection between emotional states and aggressive actions. Another important theory is the social learning theory, proposed by Albert Bandura. This theory posits that aggression is learned through observation and imitation of others, particularly role models. It highlights the influence of environmental factors and experiences in shaping aggressive behavior, suggesting that individuals can learn to be aggressive by watching others.
