Final answer:
A psychologist who is a psychodynamic personality theorist believes that personality is shaped by inner forces and early experiences, as suggested by Sigmund Freud's theory, with an emphasis on unconscious processes and the interactions of the id, ego, and superego.
Step-by-step explanation:
If a psychologist identifies herself as a psychodynamic personality theorist, she is most likely to believe that inner forces shape personality and motivate behavior. This viewpoint is in line with Sigmund Freud's psychodynamic theory of personality, which posits that unconscious drives, particularly those influenced by sex and aggression, as well as childhood experiences, significantly influence our personality development.
Furthermore, Freud introduced the concepts of the id, ego, and superego to illustrate the dynamic interactions within the psyche that contribute to personality. The theory suggests that personality and behavior are the result of conflicts and compromises among these three aspects of the psyche. Neo-Freudian theorists also emphasize the importance of social environment and culture in personality development, modifying and extending Freud's original ideas.
