The Self is a key construct in several schools of Psychology. Usages differ between theorists and fields of study, but in general the self refers to the conscious, reflective personality of an individual. The study of the self involves significant methodological problems, especially concerning consciousness. Some of these are taken up in philosophy of mind and metaphysics.
Perhaps the best-known account of the self is Freud's theory of the tri-partite function of the self, involving ego, id and superego processes. Many theorists, however, would bring under the heading of the self only what Freud regarded as ego processes.
Major concepts within the theory of the self include:
- self awareness
- self concept
- self control
- self destructive behavior including self mutilation
- self disclosure
- Laing's "divided self" theory of schizophrenia
- self efficacy
- self esteem
- self monitoring
- the self-perception theory of attitude change
- self talk
