Answer:
Freud believed that human behavior is the result of the id, ego, and superego all interacting with one another. Freud believed that the id, ego, and superego are in constant conflict and that adult personality and behavior is a result of these internal struggles throughout childhood. Freud divided human consciousness into three levels of awareness: the conscious, preconscious, and subconscious. The conscious mind consists of everything inside of our awareness, and the subconscious mind is a reservoir of feelings, thoughts, urges, and memories that are outside of our conscious awareness. Preconscious thought is somewhat of the middle ground between conscious and subconscious, as it is information that is readily available, but not being used by the conscious mind. According to Freud, the id is the primitive and instinctual part of the mind that contains sexual and aggressive drives and hidden memories, the super-ego operates as a moral conscience, and the ego is the realistic part that mediates between the desires of the id and the super-ego. The reality principle is kind of like a buffer between our innate desires and how we act outwardly to the world around us. For example, if someone's subconscious wanted to start singing loudly, but that person was in a quiet library, their reality principle would adjust themselves to their environment and they would most likely not start singing. Freud thought that a persons personality was based on their relationship with the id, ego, and superego and how well they controlled their repressed desires.
