“Far from the heart far from the eye”: Evidence from the Capgras Delusion

Capgras syndrome is characterized by the belief that a significant other has been replaced by an identical-looking impostor. These patients have no difficulties with visual recognition but fail to show a skin conductance response (SCR) to the objects of the delusion.
