The delusion of inanimate doubles. Implications for understanding the Capgras phenomenon.
The Capgras delusion has long been held to be specific for close personal relationships. This paper presents evidence that this is not the case and the implications of this for accepting psychodynamic explanations of the phenomenon are discussed. Parallels are drawn with the condition prosopagnosia and a hypothesis presented that any specificity is apparent rather than real. It is proposed that both prosopagnosia and the Capgras symptom represent abnormalities of visual perception occurring at different stages of this neurophysiological process.
