In psychoanalysis, decathexis is the withdrawal of cathexis from an idea or instinctual object.〔(Paul Denis, 'Decathexis' )〕 Cathexis is the process of investment of mental or emotional energy in a person, object, or idea.〔Hall, Calvin S. ''A Primer of Freudian Psychology''. New York: Mentor, 1954.〕 ==Narcissism== In narcissistic neurosis, cathexis is withdrawn from external instinctual objects (or rather their unconscious representations)〔J-M Quinodoz, ''Reading Freud'' (2005) p. 145〕 and turned on the ego - a process Freud highlighted in the Schreber case, and linked to the subject's ensuing megalomania.〔Sigmund Freud, ''Case Histories II'' (PFL 9) p. 208-11〕 A similar decathexis of energy has been linked to the emergence of symptoms of hypochondriasis,〔Otto Fenichel, ''The Psychoanalytic Theory of Neurosis'' (1946) p. 262〕 as well as of melancholia.〔Sigmund Freud, ''On Metapsychology'' (PFL 11) p. 266-7〕 André Green saw decathexis as the product of the death drive, blanking out the possibility of thinking by a process of what he called de-objectilizing.〔J-M Quinodoz, ''Reading Freud'' (2005) p. 134〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Decathexis」の詳細全文を読む スポンサード リンク
