Which statement is a biological finding associated with psychopathy?

• A. May demonstrate reduced fear in anticipation of unpleasant or painful stimuli
• B. Do not exhibit global neuropsychological deficits
• C. Exhibit functional brain deficits
• D. Cerebral cortexes are less active during emotional processing

Answer: (A)

Biological findings in psychopathy often center on emotion processing and arousal, especially fear. A robust pattern is blunted fear responses, particularly when an aversive event is anticipated. This reflects reduced autonomic arousal and altered amygdala-driven processing of threat, which helps explain why some individuals with psychopathic traits show fearlessness or disinhibited behavior in anticipation of unpleasant outcomes. So, the statement that they may demonstrate reduced fear in anticipation of unpleasant or painful stimuli captures this well-supported biological pattern. Other options are broader or less consistent. Claims of global neuropsychological deficits are not universal across all domains. Saying there are functional brain deficits is true but vague and does not pinpoint the emotion-specific finding that is most consistently observed. The idea that cerebral cortices are less active during emotional processing oversimplifies the issue, as the core differences often involve limbic and connectivity patterns related to fear and threat processing rather than a blanket cortical hypoactivity.
