This approach has garnered some empirical support. However the extent to which Lynam s model captures children who resemble psychopathy with regard to the core affective and interpersonal features remains unclear. Methods In the present study we investigated this issue within a large community sample of youth N 617 . Four groups non-HIA-CP HIA-only CP-only and HIA-CP defined on the basis of teacher reports of the Strengths and Difficulties Questionnaire SDQ were compared with respect to parent-reported psychopathic-like traits and subjective emotional reactivity in response to unpleasant emotionally-laden pictures from the International Affective Pictures System IAPS . Results Results did not support Lynam s model. HIA-CP children did not appear most psychopathic-like on dimensions of callous-unemotional and narcissistic personality nor did they report reduced emotional reactivity to the IAPS relative to the other children. Post-hoc regression analyses revealed a significant moderation such that elevated HIA weakened the association between CP and emotional underarousal.

In one approach to doing so Lynam 1 proposed locating the future psychopath within the current childhood diagnostic nomenclature. He hypothesized .
