One of the classic hypotheses of social psychology, first proposed by Dollard and his colleagues in 1939, states that frustration is the primary and proximate cause of aggressive behavior, meaning that the feeling of frustration that occurs when a person is denied satisfaction or prevented from achieving his goals inevitably leads to the emergence of aggressive tendencies, which can take the form of direct or indirect behavior directed at the source of frustration or others Alternatives. The frustration-aggression hypothesis has provided an important framework for understanding the relationship between stress and frustration and the occurrence of aggressive behavior. However, it is no longer seen as a linear, deterministic relationship, but rather as a psychological mechanism that increases the likelihood of aggression but interacts with other internal and external factors that determine whether aggression will actually occur.
