The neo-Freudians were psychologists whose work followed from Freud’s. They generally agreed with Freud that childhood experiences matter, but they decreased the emphasis on sex and focused more on the social environment and effects of culture on personality. Some of the notable neo-Freudians are Alfred Adler, Carl Jung, Erik Erikson, and Karen Horney. The neo-Freudian approaches have been criticized, because they tend to be philosophical rather than based on sound scientific research. For example, Jung’s conclusions about the existence of the collective unconscious are based on myths, legends, dreams, and art. In addition, as with Freud’s psychoanalytic theory, the neo-Freudians based much of their theories of personality on information from their patients.
