Threat sensitivity (THT) and weak inhibitory control (or disinhibition; DIS) are trait constructs that relate to multiple types of psychopathology and can be assessed psychoneurometrically (i.e., using self-report and physiological...
Recent research initiatives have called for an increased use of biological concepts and measures in defining and studying mental health problems, but important measurement-related challenges confront efforts in this direction. This...
The current work sought to operationalize constructs of the triarchic model of psychopathy in chimpanzees (), a species well-suited for investigations of basic biobehavioral dispositions relevant to psychopathology. Across three studies, ...
The current study undertook analyses of genealogical data from a sample of 178 socially-housed chimpanzees () with well-documented pedigrees, to clarify the etiologic bases of triarchic psychopathy dimensions and the influence of early...
The National Institute of Mental Health Research Domain Criteria initiative (Insel et al., 2010) calls for a focus on biologically meaningful dimensional constructs in the study of clinical problems. Examples are needed of how Research...
The National Institute of Mental Health's Research Domain Criteria (RDoC) initiative calls for the incorporation of neurobiological approaches and findings into conceptions of mental health problems through a focus on biobehavioral...
Shortcomings of approaches to classifying psychopathology based on expert consensus have given rise to contemporary efforts to classify psychopathology quantitatively. In this paper, we review progress in achieving a quantitative and...
Recent research has sought to understand how individuals high in psychopathic traits perceive pain in others (Decety, Skelly, & Kiehl, 2013; Marsh et al., 2013). Perception of pain in others is presumed to act as a prosocial signal, and...
Externalizing proneness, or trait disinhibition, is a concept relevant to multiple high-impact disorders involving impulsive-aggressive behavior. Its mechanisms remain disputed: major models posit hyperresponsive reward circuitry or...
We examined whether striatal dopamine moderates the impact of externalizing proneness (disinhibition) on reward-based decision-making. Participants completed disinhibition and substance abuse subscales of the brief form Externalizing...
The fearlessness model posits that psychopathy is underpinned by a deficiency in the capacity to experience fear, predisposing to other features of the condition, such as superficial charm, guiltlessness, callousness, narcissism, and...
