Answer:
c. Use the same research methods Freud advocated.
Explanation:
Neo-Freudians are those psychologists who based their psychological approaches according to the methods advocated by Sigmund Freud. But their main deviation from the original Freudian method is that they focus more on the inter-personal relationship rather than the scientific.
For neo-Freudians, their emphasis lied on the socio-cultural aspects of psychoanalysis more than the scientific aspect. So, while Freud may have advocated more on the scientific aspect of psychology, the neo-Freudians prefer to lean more towards the emotional/ social/ cultural aspect of psychology.
Thus, the correct answer is option c.
