Psychopathology is a branch of psychological science whose contributions have theoretical and practical value for psychology and psychiatry, with which it borders. Currently, the intense development that science is experiencing is determined by scientific-technical progress: in psychology, in addition to these general causes that affect 20th century science, one factor must be taken into account: the human factor. Psychopathology, as a psychological discipline, is based on the laws of development and structure of the psyche in a normal state; studies the laws of disintegration of psychic activity and the properties of personality, comparing them with the laws of formation and development of psychic processes as a norm; It analyzes the regularity in the accelerations of the brain's reflective activity, which is why it is distinguished in terms of the objectives of its activity from psychiatry. New and complex science, adjacent to psychology and psychiatry without being confused with them, psychopathology has achieved great development in the United States and Russia, from where it radiates to Europe.
