The document discusses Sigmund Freud's theories of the conscious and unconscious mind. Freud believed the conscious mind is like the tip of an iceberg, with most of the mind being the unconscious - containing desires, memories, and experiences we are unaware of. Three techniques discussed for accessing the unconscious are psychoanalysis, where talking to a therapist can reveal hidden desires; word association, where a subject rapidly says the first word that comes to mind in response to a word; and the Rorschach inkblot test, where a subject interprets inkblots and their responses are analyzed. While criticized as subjective, these techniques aimed to better understand a patient's mind and problems.
