Psychoanalysis is a form of therapy that aims to help clients gain insight into the unconscious factors that contribute to their psychological issues. The therapist works to uncover unconscious conflicts, early life experiences, and repressed emotions that may be contributing to the client's symptoms. This type of therapy is particularly useful for clients with long-standing and complex psychological issues. Cognitive therapies (A) focus on examining and modifying negative thought patterns, while systematic desensitization (B) is a type of exposure therapy used to treat anxiety disorders. Light exposure therapy (C) is used to treat seasonal affective disorder and other mood disorders related to changes in light exposure.
