Another strength of Freud's theory is its ability to explain human behaviour. Freud's theory is controversial in many ways, and occasionally bizarre, but it has nevertheless had a huge influence on psychology and contemporary thought. Alongside behaviourism, the psychodynamic approach remained a key force in psychology for the first half of the 20th century and has been used to explain a wide range of phenomena including personality development, the origins of psychological disorders, moral development and gender identity. The approach is also significant in drawing attention to the connection between experiences in childhood, such as our relationship with our parents, and our later development.
This suggests that, overall, the psychodynamic approach has had a positive impact on psychology - and also on literature, art and other human endeavours.
