Sigmund Freud and The Psychoanalytic Theory

Discuss how the theory can be implemented in the field of Human Development and in working with children and their families. In your research look for who is the researcher, what was their work all about, why did they choose to study in this field, and what was the main source of motivation to complete their research.... What was the theory they worked on, and how is that applicable to working with children and families now?
