Poor fear conditioning characterizes adult psychopathy and criminality, but it is not known whether it is related to aggressive/antisocial behavior in early childhood.
Using a differential, partial reinforcement conditioning paradigm, electrodermal activity was recorded from 200 male and female children at ages 3, 4, 5, 6, and 8 years. Antisocial/aggressive and hyperactive-inattentive measures were collected at age 8.
Poor electrodermal fear conditioning from ages 3 to 8 years was associated with aggressive behavior at age 8 in both males and females.
Results indicate that the relationship between poor fear conditioning and aggression occurs early in childhood. Enhanced electrodermal fear conditioning may protect children against future aggressive/violent behavior. Abnormal amygdala functioning, as indirectly assessed by fear conditioning, may be one of the factors influencing the development of childhood aggression.

    ABSTRACT: Youth exposed to family aggression may become more aggressive themselves, but the mechanisms of intergenerational transmission are understudied. In a longitudinal study, we found that adolescents' reduced neural activation when rating their parents' emotions, assessed via magnetic resonance imaging, mediated the association between parents' past aggression and adolescents' subsequent aggressive behavior toward parents. A subsample of 21 youth, drawn from the larger study, underwent magnetic resonance imaging scanning proximate to the second of two assessments of the family environment. At Time 1 (when youth were on average 15.51 years old) we measured parents' aggressive marital and parent-child conflict behaviors, and at Time 2 (≈2 years later), we measured youth aggression directed toward parents. Youth from more aggressive families showed relatively less activation to parent stimuli in brain areas associated with salience and socioemotional processing, including the insula and limbic structures. Activation patterns in these same areas were also associated with youths' subsequent parent-directed aggression. The association between parents' aggression and youths' subsequent parent-directed aggression was statistically mediated by signal change coefficients in the insula, right amygdala, thalamus, and putamen. These signal change coefficients were also positively associated with scores on a mentalizing measure. Hypoarousal of the emotional brain to family stimuli may support the intergenerational transmission of family aggression.

    • "In a prospective study, fear conditioning using electrodermal responsivity was assessed in children at ages 3, 4, 5, 6, and 8. It was shown that poor fear conditioning from ages 3–8 years is associated with aggression at age 8 (Gao et al. 2010a). Furthermore , it appeared that poor fear conditioning at age 3 predisposes to crime at age 23 (Gao et al. 2010b). "

    ABSTRACT: In this review, a conceptualization of oppositional defiant (ODD) and conduct disorder (CD) is presented according to which social learning processes in these disorders are affected by neurocognitive dysfunctions. Neurobiological studies in ODD and CD suggest that the ability to make associations between behaviors and negative and positive consequences is compromised in children and adolescents with these disorders due to reduced sensitivity to punishment and to reward. As a result, both learning of appropriate behavior and learning to refrain from inappropriate behavior may be affected. Likewise, problem solving is impaired due to deficiencies in inhibition, attention, cognitive flexibility, and decision making. Consequently, children and adolescents with ODD and CD may have difficulty learning to optimize their behavior in changeable environments. This conceptualization of ODD and CD is relevant for the improvement of the effect of psychological treatments. Behavioral and cognitive-behavioral interventions that have been shown to be modestly effective in ODD and CD are based on social learning. Limited effectiveness of these interventions may be caused by difficulties in social learning in children and adolescents with ODD and CD. However, although these impairments have been observed at a group level, the deficits in reward processing, punishment processing, and cognitive control mentioned above may not be present to the same extent in each individual with ODD and CD. Therefore, the neurocognitive characteristics in children and adolescents with ODD and CD should be assessed individually. Thus, instead of delivering interventions in a standardized way, these programs may benefit from an individualized approach that depends on the weaknesses and strengths of the neurocognitive characteristics of the child and the adolescent.

    • "However, Dadds and colleagues have included children as young as 3 years old in studies investigating the measurement of CU, as well as the association between empathy and psychopathy (Dadds et al. 2005, 2009). Moreover, Raine and colleagues established that poor fear conditioning, fearlessness, and stimulation seeking—temperamental characteristics related to CU—measured at age 3 years were predictive of childhood aggression, adult criminality, and adult psychopathy (Gao et al. 2010a, 2010b; Glenn et al. 2007; Raine et al. 1998).

    ABSTRACT: This study evaluated a five-item screening measure of Callous Unemotional (CU) traits using items drawn from the Preschool Form of the Achenbach System of Empirically Based Assessment (ASEBA). Using data from the Durham Child Health and Development study (N=178), confirmatory factor analyses demonstrated that CU items could be distinguished from Attention Deficit/Hyperactivity Disorder (ADHD) and Oppositional Defiant (ODD) items. The two-year stability (N=137) of CU (ϕ=.84) was comparable to that of ADHD (ϕ=.79) and ODD (ϕ=.69). Three groups of children were selected based on parent-rated ODD and CU behaviors at the 36-month assessment (N=37; ODD+CU, N=7; ODD-only, N=12; non-ODD, N=18). Multiple measures of infant temperament predicted group membership with 84% accuracy. Consistent with Frick and Morris' (Journal of Clinical Child and Adolescent Psychology 33(1):54-68, 2004) hypotheses, ODD+CU and ODD-only children exhibited temperamental profiles in infancy that were consistent with low fear and emotionally dysregulated pathways into conduct problems, respectively.
