Id, ego and super-ego are the three parts of the psychic apparatus defined in Sigmund Freud’s structural model of the psyche; they are the three theoretical constructs in terms of whose activity and interaction mental life is described.
The id, ego and super-ego are functions of the mind rather than parts of the brain and do not correspond one-to-one with actual somatic structures of the kind dealt with by neuroscience.
The concepts themselves arose at a late stage in the development of Freud’s thought: the “structural model” was first discussed in his 1920 essay “Beyond the Pleasure Principle” and was formalised and elaborated upon three years later in his “The Ego and the Id”.
The id is the only component of personality that is present from birth. This aspect of personality is entirely unconscious and includes of the instinctive and primitive behaviors. According to Freud, the id is the source of all psychic energy, making it the primary component of personality.
The id is driven by the pleasure principle, which strives for immediate gratification of all desires, wants, and needs. If these needs are not satisfied immediately, the result is a state anxiety or tension. For example, an increase in hunger or thirst should produce an immediate attempt to eat or drink. The id is very important early in life, because it ensures that an infant’s needs are met. If the infant is hungry or uncomfortable, he or she will cry until the demands of the id are met.
However, immediately satisfying these needs is not always realistic or even possible. If we were ruled entirely by the pleasure principle, we might find ourselves grabbing things we want out of other people’s hands to satisfy our own cravings. This sort of behavior would be both disruptive and socially unacceptable. According to Freud, the id tries to resolve the tension created by the pleasure principle through the primary process, which involves forming a mental image of the desired object as a way of satisfying the need.
The ego is the component of personality that is responsible for dealing with reality. According to Freud, the ego develops from the id and ensures that the impulses of the id can be expressed in a manner acceptable in the real world. The ego functions in both the conscious, preconscious, and unconscious mind.
The ego operates based on the reality principle, which strives to satisfy the id’s desires in realistic and socially appropriate ways. The reality principle weighs the costs and benefits of an action before deciding to act upon or abandon impulses. In many cases, the id’s impulses can be satisfied through a process of delayed gratification—the ego will eventually allow the behavior, but only in the appropriate time and place.
The ego also discharges tension created by unmet impulses through the secondary process, in which the ego tries to find an object in the real world that matches the mental image created by the id’s primary process.
The super-ego’s demands often oppose the id’s, so the ego sometimes has a hard time in reconciling the two. To overcome this the ego employs defense mechanisms. The defense mechanisms are not done so directly or consciously. They lessen the tension by covering up our impulses that are threatening. Ego defense mechanisms are often used by the ego when id behavior conflicts with reality and either society’s morals, norms, and taboos or the individual’s expectations as a result of the internalization of these morals, norms, and their taboos.
Denial, displacement, intellectualisation, fantasy, compensation, projection, rationalization, reaction formation, regression, repression, and sublimation were the defense mechanisms Freud identified. However, his daughter Anna Freud clarified and identified the concepts of undoing, suppression, dissociation, idealization, identification, introjection, inversion, somatisation, splitting, and substitution.
The last component of personality to develop is the superego. The superego is the aspect of personality that holds all of our internalized moral standards and ideals that we acquire from both parents and society—our sense of right and wrong. The superego provides guidelines for making judgments. According to Freud, the superego begins to emerge at around age five.
There are two parts of the superego:
The ego ideal includes the rules and standards for good behaviors. These behaviors include those which are approved of by parental and other authority figures. Obeying these rules leads to feelings of pride, value and accomplishment.
The conscience includes information about things that are viewed as bad by parents and society. These behaviors are often forbidden and lead to bad consequences, punishments or feelings of guilt and remorse.
The superego acts to perfect and civilize our behavior. It works to suppress all unacceptable urges of the id and struggles to make the ego act upon idealistic standards rather that upon realistic principles. The superego is present in the conscious, preconscious and unconscious.
