Sigmund Freud's theory of psychoanalysis was influential in developing talk therapy and the notion that simply discussing problems can help solve mental health issues. Freud believed that childhood experiences and unconscious thoughts, feelings, and motivations play a role in mental illness. His theory divided the mind into the id, ego, and super ego, representing basic instincts, reality, and morality, respectively. Freud emphasized the importance of early childhood experiences in developing one's unconscious mind and emotional well-being as an adult. Practitioners can support children's emotional needs through play, creative expression, and introducing counseling professionals.
