cathexis n : (psychoanalysis) the libidinal energy invested in some idea or person or object; "Freud thought of cathexis as a psychic analog of an electrical charge" [syn: charge] [also: cathexes (pl)]
Etymologyκάθεξις (kathexis, holding, retention). Entered English language as a translation for the common everyday German word Besetzung, which in this context means "occupation" in the sense of a position or something being occupied or filled, and not a military occupation of a place or the filling of job positions (although it can also mean either of these in other contexts). In English translations, a Greek word was used to be more scientific.
In psychodynamics, cathexis is defined as the process of investment of mental or emotional energy in a person, object, or idea. This concept was developed by Sigmund Freud in 1922. In psychoanalysis, cathexis is the libido's charge of energy. Freud often described the functioning of psychosexual energies in mechanical terms, influenced perhaps by the dominance of the steam engine at the end of the 19th century. In this manner, he also tended to think of the libido as a producer of energies.
Freud often represented frustration in libidinal desires as a blockage of energies that have, or would eventually build up and require release in alternative ways. This release could occur, for example, by way of regression and the "re-cathecting" of former positions, that is, fixation at the oral phase or anal phase and the enjoyment of former sexual objects ["object-cathexes"], including autoeroticism).
When the ego blocks such efforts to discharge one's cathexis by way of regression, that is, when the ego wishes to repress such desires, Freud uses the term "anti-cathexis" or counter-charge. Like a steam engine, the libido's cathexis then builds up until it finds alternative outlets, which can lead to sublimation or to the formation of sometimes disabling symptoms.
