Callous-unemotional, impulsive-irresponsible, and grandiose-manipulative traits: Distinct associations with heart rate, skin conductance, and startle responses to violent and erotic scenes
2017 — Multidimensional psychopathy and psychophysiology
Finding
CU, impulsive-irresponsible, and grandiose-manipulative dimensions showed distinguishable associations with heart rate, skin conductance, startle, and reported affect during emotional scenes.
Why it matters
The study weakens the idea that 'psychopathy' should be assigned one undifferentiated physiological profile.
Inference boundary
Dimension-specific association is not the same as a dimension-specific causal mechanism.
