The term “displacement of affect” refers to various cases when, when a person commits some act, an affect (emotional reaction) arises not because it corresponds to the content of this affect in meaning, but, on the contrary, contrary to its real or imaginary content. Although there are a variety of types of movement of affects, in all cases they are observed to be directed towards what remains outside of what is directly experienced, while it is these latter that are its immediate source. Various types of displacement are described, there is a special theory about the psychogenic development of personality, this topic is still popular today. Irradiation is the spread of the emotional state and behavior of one person to surrounding people.\n\nIn the history of cultural development, the study of affective behavior and psychotherapy has always been a subject of philosophical interest. This is explained by the interest of thinkers in man as a sensory being and the question that always accompanies such interest about the origin and essence of affective life. Psychological concepts of this time assign the main role in this regard to feeling, although there are also concepts that consider the soul as an affective entity. The contribution of many past scientists to the development of psychotherapy and understanding the meaning of mental causation is based mainly on the work of Hippocrates and Aristotle.
