Final answer:
Freud is associated with developing foundational theories in psychology, including psychoanalysis, the division of the mind into the id, ego, and preconscious, and stressing the significance of the unconscious in shaping behavior.
Step-by-step explanation:
The psychological concepts associated with Sigmund Freud are psychoanalysis, the id, the ego, and the preconscious. Freud's influential theory suggested that the unconscious mind plays a significant role in determining conscious behavior. This framework is essential to the foundation of Freud's psychoanalytic theory, which explores the psychological forces shaping personality and behavior.
Sigmund Freud is credited with presenting the first comprehensive theory of personality focused on the idea that humans have unconscious parts of their minds affecting their behavior. Freud divided the psyche into three parts: the id, representing innate biological instincts; the ego, conscious reasoning; and the superego, internalizing societal norms and morality. These components interact with the preconscious and unconscious mind, affecting an individual's conscious thoughts and behaviors.
Freud utilized various techniques such as dream analysis, free association, and examination of slips of the tongue to tap into the hidden depths of the unconscious. The consideration of these techniques and Freudian thought remain relevant in the history of psychological studies, and although some of his ideas have not withstood the rigors of modern research, his contributions have paved the way for subsequent psychological theories.
