A common belief is that narcissism is a manifestation of high self-esteem. Here, we argue that self-esteem and narcissism are fundamentally distinct and have unique early physiological indicators. We hypothesized that children predisposed to narcissism would show elevated, whereas children predisposed to high self-esteem would show lowered, physiological arousal in social-evaluative contexts. We tested this in a prospective study including 113 children, who were first assessed at age 4.5, a critical age when children begin evaluating themselves through others' eyes. At age 4.5, children sang a song in front of an audience while being videotaped. Children's physiological arousal (skin conductance, heart rate, and heart rate variability) was assessed while children anticipated, performed, and recovered from the singing task. At age 7.5, children's narcissism and self-esteem levels were assessed. Consistent with our predictions, children predisposed to higher narcissism levels showed elevated skin conductance levels during anticipation. Their skin conductance levels further rose during performance (but less so than for other children) and failed to return to baseline during recovery. By contrast, children predisposed to higher self-esteem levels showed lowered skin conductance levels throughout the procedure. The effects emerged for skin conductance but not heart rate or heart rate variability, suggesting that arousal was sympathetically driven. Effects were larger and more robust for self-esteem than for narcissism. Together, these findings uncover distinct physiological indicators of narcissism and self-esteem: Narcissism is predicted by indicators reflecting early social-evaluative concerns, whereas self-esteem is predicted by indicators reflecting an early sense of comfort in social-evaluative contexts.
