Freud's mature theorizing about human morality entrenched the functioning of the superego in anxiety stemming from the fear of punishment, a view with which many later psychoanalysts took issue, producing a debate as to the distinction between superego and conscience. This debate would later be mirrored more broadly in academic psychology concerning distinctions between shame and guilt. This is an area where the clinical observations and theoretical discussions of psychoanalysis have subtly guided research in cognitive psychology and the cognitive and affective neurosciences. These areas, in turn, have both clarified and supported psychoanalytic theory and practice without negating the rich phenomenological and theoretical basis on which psychoanalysis rests.
