Development of personality and the problem of the leading activity

The concept of "the leading activity" constituting basic ontogenetical stages in the development of personality is a result of the unlawful reduction of the personality development to the development of psyche, and of the development of psyche - to the development of cognitive processes. Comprehensive and harmonious development of personality can not be determined only by a "leading activity". Historical-psychological analysis makes it possible to reveal causes of the above-mentioned double reduction.
