When this theory was discovered, Freud involved three concepts to the personality; the id, the ego, and the superego. The Id is the only element of the personality that is present from birth. This is about the desires, wants, and needs of an individual. This is particularly important in early life because an infant has needs that should be met. For example, if there is a baby that is hungry and will not stop crying until he or she gets fed, that would be where the id rules in. In this structure of the id, it is quite unorganized because it demands immediate satisfaction with no thoughts of manners and proper action.. If the needs are not met, this may cause anxiety and tension. The id does not know the difference between good and bad, it only seeks for gratification, but this is where the ego comes into place.
The ego makes sure that the necessities of the id are handled in an appropriate behavior that will benefit an individual in the long run. The id will strive for satisfaction anywhere and anytime, but the ego will take charge and only allow the behavior in the right time and place. Functions of the ego are only in the conscious and unconscious mind. The id has a structure of the personality that is unorganized, whereas, the ego is more organized. Since the ego is more organized, it is liable for common sense, judgment, defense, taking in information, and memory. This part of the personality helps us separate out what is real, organize our thoughts, and make sense of the world around us. (Ruth 2006) Also, our bodies have defense
