Which technique did Freud use to uncover unconscious thoughts?

Freud utilized the technique of free association to uncover unconscious thoughts effectively. This method involves the patient speaking freely about their thoughts, feelings, and associations without censorship or filtering. The idea behind free association is that as individuals speak openly, hidden memories and thoughts that reside in the unconscious mind may surface. This technique encourages the exploration of thoughts that the person may not readily acknowledge, revealing underlying motivations, conflicts, or desires that influence their behavior.

In the context of Freud's psychoanalytic therapy, free association served as a tool to facilitate insight and understanding of the unconscious mind, allowing patients to develop awareness of their inner experiences and how they affect their current mental states. This process was crucial for Freud's therapeutic goals and the advancement of psychoanalysis as a whole.
