Psychopathy, Executive Functions, and Neuropsychological Data: a Response to Sifferd and Hirstein

Original Paper

Abstract

Katrina Sifferd and William Hirstein, in their paper ‘On the criminal culpability of successful and unsuccessful psychopaths’, argue that neuropsychological data show that unsuccessful psychopaths have diminished mental capacities that warrant a partial or diminished responsibility defence. We respond that the currently available neuropsychological evidence does not warrant their conclusion that unsuccessful psychopaths should not be deemed completely legally responsible. Instead, we maintain that the current state of this type of research suggests that psychopaths might be suffering very specific cognitive impairments. However, the impact that these impairments might have on the specific criminal behaviours that courts have to assess is far from clear.
