- There has been a longstanding interest in autonomic activity in relation to criminal deviancy, antisocial behavior (ASB), and psychopathy. Among the autonomic measures studied to date, considerable evidence supports low rest-ing heart rate (HR) early in life as one of the most robust predictors of later ASB (Farrington, 1997). Some studies have examined stimulation seeking and fearlessness as possible trait factors accounting for the low HR/ASB rela-tionship (Hammerton et al., 2017; Portnoy et al., 2014; Sijstema et al., 2010), but the individual difference basis of this relationship remains unclear. The current study tested for associations of resting HR at ages 9–10 with triarchic psychopathy traits of boldness, meanness, and disinhibition along with ASB later in life (ages 19–20) among participants (N = 687) from a longitudinal investigation, the Risk Factors for Antisocial Behavior (RFAB; Baker et al., 2013) project. Resting HR was negatively associated with both violent and nonviolent behavior, and with externalizing problems more broadly. It was also related negatively to triarchic traits of boldness and disinhibition, with the relationship somewhat stronger for boldness. Importantly, boldness and disinhibition each accounted for significant variance in associations of low resting HR with particular types of ASB. Implications of these findings for our understanding of the nature and bases of the low HR–antisocial behavior relationship will be discussed.

- There has been a longstanding interest in relationships between autonomic activity during fear conditioning paradigms and antisocial behavior and psychopathy. A considerable body of work has explored electrodermal and cardiovascular responses both in anticipation of, and in response to, fear conditioning paradigms in antisocial participants (Hare 1965; Hare & Quinn, 1976). However, there is a lack of work exploring these associations in adolescent populations, and how these associations may relate to the triarchic model of psychopathy (Patrick, Fowles, & Krueger, 2009). The current study examined relationships between skin conductance responses (SCRs) and heart rate reactivity (HRR) to a countdown task at ages 9– 10, and the triarchic psychopathy traits at ages 9– 10, 14– 15, and 19– 20 in a longitudinal sample (N = 695) of twins from the Risk Factors for Antisocial Behavior (RFAB; Baker et al., 2013) project. Children and adolescents high in boldness, both rated by themselves and their parents, demonstrated reduced skin conductance both in anticipation of and in reaction to the loud blast. Similar patterns were also demonstrated for heart rate (HR); children and adolescents high in boldness had less HR change during the countdown, and reduced HRR to the blast itself. Implications of these findings for our understanding of the role of boldness in autonomic reactivity to fear conditioning paradigms will be discussed.

- Diminished emotional capacity is a core characteristic of psychopathic personality. We examined behavioral and electrophysiological differences in attentional bias to emotional material in 34 healthy individuals rated high or low in psychopathic traits using the short form of the Psychopathic Personality Inventory-Revised (18 high-trait, 16 low-trait). While performing an emotional Stroop task, high-trait participants displayed reduced emotional modulation of the late positive potential (LPP, 400-600ms), and early anterior positivity (EAP, 200-300ms) amplitudes. Results suggest blunted bias to affective content in psychopathic personality, characterized by diminished early capture to emotional salience (EAP) and dampened cognitive emotional processing (LPP).

Facial reactions to happy and angry facial expressions: Evidence for right hemisphere dominance

Tidskriftsartikel (refereegranskat)abstract
- Previous research on asymmetric effects of emotional expression and brain-hemispheric asymmetry has supported opposing theories of hemispheric dominance in the control of emotional reactions. In the present study, 32 subjects were exposed to pictures of happy and angry facial stimuli while facial electromyographic (EMG) activity from the zygomatic major and the corrugator supercilii muscle regions was detected from the left and right sides of the face. The subjects reacted spontaneously and rapidly with larger zygomatic EMG activity to happy facial stimuli and larger corrugator EMG activity to angry stimuli. These distinct reactions were significantly larger on the left side of the face. It is concluded that the present results support the hypothesis that the right brain hemisphere is predominantly involved in the control of spontaneously evoked emotional reactions.
