A subpersonality is, in humanistic psychology, transpersonal psychology and ego psychology, a personality mode that activates (appears on a temporary basis) to allow a person to cope with certain types of psychosocial situations.[1] Similar to a complex,[2] the mode may include thoughts, feelings, actions, physiology and other elements of human behavior to self-present a particular mode that works to negate particular psychosocial situations.[1][3] American transpersonal philosopher Ken Wilber and English humanistic psychologist John Rowan suggested that the average person has about a dozen subpersonalities.[1]
Many schools of psychotherapy see subpersonalities as relatively enduring psychological structures or entities that influence how a person feels, perceives, behaves, and sees themselves. John Rowan, who is particularly known for his work on the nature of a subpersonality, described it as a 'semipermanent and semi-autonomous region of the personality capable of acting as a person'.[4]
Thereby, allegedly subpersonalities are able to perceive consciousness as something separate from themselves, as well as domestic image attached to these elements.[1] Ken Wilber defined subpersonalities as "functional self-presentations that navigate particular psychosocial situations".[1] For example, if a harsh critic responds with judgmental thoughts, anger, superior feelings, critical words, punitive action, and/or tense physiology when confronted with their own and/or others' fallibility, that is a subpersonality of the harsh critic kicking in to cope with the confrontation situation.[1]
