    with Stuart F. White, Sarah J. Brislin, Harma Meffert, and R. James R. Blair
    Journal of Personality Disorders 27 (1). 2013.
    The current study examined whether Callous-Unemotional (CU) traits, a core component of psychopathy, modulate neural responses of participants engaged in a social exchange game. In this task, participants were offered an allocation of money and then given the chance to punish the offerer. Twenty youth participated and responses to both offers and the participant’s punishment (or not) of these offers were examined. Increasingly unfair offers were associated with increased dorsal anterior cingulat…Read more
  • Reduced Amygdala Response in Youths With Disruptive Behavior Disorders and Psychopathic Traits: Decreased Emotional Response Versus Increased Top-Down Attention to Nonemotional Features
    with Stuart F. White, Abigail A. Marsh, Katherine A. Fowler, Julia C. Schechter, Christopher Adalio, Kayla Pope, Daniel S. Pine, and R. James R. Blair
    American Journal of Psychiatry 169 (7): 750-758. 2012.
    Youths with disruptive behavior disorders and psychopathic traits showed reduced amygdala responses to fearful expressions under low attentional load but no indications of increased recruitment of regions implicated in top- down attentional control. These findings suggest that the emotional deficit observed in youths with disruptive behavior disorders and psychopathic traits is primary and not secondary to increased top- down attention to nonemotional stimulus features
