Psychopharmacology (Berl) 209:225-32. 2010..Perceptions of trustworthiness are associated with detection of positive facial affect, which suggests that oxytocin may enhance the recognition of positive facial affect. The present study tests this hypothesis...
Adolescents with psychopathic traits report reductions in physiological responses to fearAbigail A Marsh

Am J Psychiatry 165:712-20. 2008..Moreover, despite high comorbidity of callous-unemotional traits and attention deficit hyperactivity disorder (ADHD), no research has attempted to distinguish neural correlates of pediatric callous-unemotional traits and ADHD...
Impaired recognition of fear facial expressions in 5-HTTLPR S-polymorphism carriers following tryptophan depletionAbigail A Marsh
Mood and Anxiety Program, National Institute of Mental Health, National Institutes of Health, Bethesda, MD 20892, USA
Psychopharmacology (Berl) 189:387-94. 2006..Acute tryptophan depletion has been associated with the processing of fear-relevant cues, such as emotional expressions, but the effect of genotype at the 5-HTTLPR has not been assessed...
Dominance and submission: the ventrolateral prefrontal cortex and responses to status cuesAbigail A Marsh
Mood and Anxiety Program, National Institute of Mental Health, National Institutes of Health, Bethesda, MD 20892, USA
J Cogn Neurosci 21:713-24. 2009..We suggest that the VLPFC retrieves information from these regions when processing hierarchy cues to facilitate socially adaptive behavior...
Accurate identification of fear facial expressions predicts prosocial behaviorAbigail A Marsh
Mood and Anxiety Disorders Program, National Institute of Mental Health, Bethesda, MD 20892, USA
Emotion 7:239-51. 2007..In Study 3, accuracy for recognizing fear proved a better predictor of prosocial behavior than gender, mood, or scores on an empathy scale...
The impact of tryptophan depletion and 5-HTTLPR genotype on passive avoidance and response reversal instrumental learning tasksElizabeth C Finger
Mood and Anxiety Disorders Program, Unit on Affective Cognitive Neuroscience, National Institute of Mental Health, Bethesda, MD 20892, USA

National Institute of Mental Health, National Institutes of Health, Bethesda, MD 20892, USA
Neurosci Biobehav Rev 32:454-65. 2008..This impairment cannot be attributed solely to task difficulty. These results suggest dysfunction among antisocial individuals in specified neural substrates, namely the amygdala, involved in processing fearful facial affect...

Department of Psychology, Harvard University, Cambridge, MA, USA
J Pers Soc Psychol 90:543-55. 2006..In Study 5, the authors found that instructing participants to adopt the target's perspective did not affect mind attribution but did lead to higher level identifications of the target's actions...
