Dual-Hormone Regulation of Psychopathy: Replicating the Findings of Welker and Colleagues (2014)

Previous research suggests that men’s psychopathy is characterized by higher testosterone levels when cortisol is high. This study attempted to replicate this work by examining testosterone, cortisol, and psychopathy within 165 men. Failing to replicate previous work, this study did not find evidence of an interaction between testosterone and cortisol.
