Full context:   Erikson was a student of Anna Freud, the daughter of Sigmund Freud, whose psychoanalytic theory and psychosexual stages contributed to the basic outline of the eight stages, at least those concerned with childhood. Namely, the first four of Erikson's life stages correspond to Freud's oral, anal, phallic, and latency phases, respectively. Also, the fifth stage of adolescence is said to parallel the genital stage in psychosexual development: Although the first three phases are linked to those of the Freudian theory, it can be seen that they are conceived along very different lines. Emphasis is not so much on sexual modes and their consequences, but on the ego qualities which emerge from each of the stages. There is an attempt also to link the sequence of individual development to the broader context of society.
