Sigmund Freud’s work on how the mind works completely changed the way modern psychology thinks about and treats mental health disorders. Given its significance, this week’s episode will focus on his psychoanalytic theory to illustrate the consequences of repressed emotions and memories on human behaviour. This will be achieved by discussing the three layers of the mind: (1) The Conscious; (2) The Preconscious; and (3) The Subconscious.
