A study by Cardiff and Swansea Universities revealed that psychopathic offenders do not experience pupil enlargement when exposed to disturbing images, unlike non-psychopaths whose pupils dilate. This suggests an emotional deficit characteristic of psychopathy. Interestingly, when shown positive images, psychopaths do exhibit normal pupil dilation, indicating that their emotional reactivity is not generalized but specific to threat-related stimuli. The research points to a distinct pattern in how psychopaths process emotions, evidenced by their physiological responses.
In our study, we found that psychopaths showed no pupil dilation in response to negative, alarming images, revealing a significant emotional deficit characteristic of psychopathy.
The unique physiological response of psychopaths to positive imagery â with pupil dilation similar to non-psychopaths â indicates an atypical reaction to emotional stimuli.
