Oedipus Complex: a term adopted by S. Freud to refer to the concept postulated by psychoanalysis whereby during infancy (pre-school age) a male child will eventually tend to identify with the father following resolution of a desire relating to his mother. The concept involves sentiments of an ambivalent nature, whereby a child would appear to desire the death of the parent of the same sex and subsequently take the place of the same, and the desire to exclusively possess the parent of the opposite sex.
Oral phase: a term used by Freud to refer to the first stage of psycho-sexual development of infants in the first 18 months of life, during which a child experiences pleasure in the oral area.
