dc.description.abstract Psychiatric disorders are the most common and costly forms of disease and injury worldwide. Despite this, our ability to accurately identify and treat these disorders is limited, due in part to deficient understanding of the underlying mechanisms of dysfunction. The current study aimed to identify genetically-influenced neurobehavioral traits--individual differences evident in both self-report and neural response--that might help improve classification and treatment of mental disorders. Results from event-related potential (ERP) components sensitive to emotional content demonstrated that a) neural processing of emotional content is heritable, b) the heritable traits of heightened trait fear and behavioral disinhibition are associated with unique emotional deficits measured by ERPs--high trait fear is associated with increased attention to threat, while behavioral disinhibition is associated with decreased attention to threat and reward, and c) the association between these heritable ERPs and self-reported traits is largely due to environmental influence. The results of this study should elucidate the pathways by which genes and environment interact to infl uence normal and abnormal behavior. en_US
