4. Basic Theories: All psychic energy is generated by the libido. Mental states were influenced by two competing forces: cathexis and anticathexis. Cathexis: 1. the investment of emotional significance in an activity, object, or idea. 2. the charge of psychic energy so invested. Anticathexis: energy derived from the Superego to run the Ego, according to Freud. The function of the anticathexis is to restrict and block cathexis from the Id for overall benefit.
