Electrodermal reactivity in an aversive countdown task
Our finding of an inverse relationship between SC reactivity and parent-rated boldness at W1 corroborates evidence from prior adult research and points to low fear (threat sensitivity) as the basis of deficient stress responding in psychopathy. The finding of contrasting predictive relations for W1 SC reactivity and W1 parent-rated boldness with ASB at W3 suggests differing roles for elements of threat sensitivity tapped by each (e.g., low anxiou…
Hypothalamic-pituitary-adrenal axis responsivity during adolescence in relation to psychopathic personality traits later in life
Psychopathic personality traits have been linked to low physiological arousal, particularly among high risk and forensic samples. A core indicator of physiological arousal is the activity of the hypothalamic-pituitary-adrenal (HPA) axis; however, findings of a link between HPA axis functioning and psychopathic personality traits have been inconsistent. Furthermore, given sex differences in both HPA axis responsivity and psychopathic personality t…

Developmental Trajectories of Delinquent and Aggressive Behavior
Neural correlates of proactive and reactive aggression in adolescent twins
Verbal and physical aggression begin early in life and steadily decline thereafter in normal development. As a result, elevated aggressive behavior in adolescence may signal atypical development and greater vulnerability for negative mental and health outcomes. Converging evidence suggests that brain disturbances in regions involved in impulse control, emotional regulation, and sensation seeking may contribute to heightened aggression. However, l…

Motor impulsivity during childhood and adolescence
In the present study, we investigated genetic and environmental effects on motor impulsivity from childhood to late adolescence using a longitudinal sample of twins from ages 9 to 18 years. Motor impulsivity was assessed using errors of commission (no-go errors) in a visual go/no-go task at 4 time points: ages 9-10, 11-13, 14-15, and 16-18 years. Significant genetic and nonshared environmental effects on motor impulsivity were found at each of th…

Genetic and environmental stability differs in reactive and proactive aggression
The aim of this study was to examine stability and change in genetic and environmental influences on reactive (impulsive and affective) and proactive (planned and instrumental) aggression from childhood to early adolescence. The sample was drawn from an ongoing longitudinal twin study of risk factors for antisocial behavior at the University of Southern California (USC). The twins were measured on two occasions: ages 9–10 years ( N =1,241) and 11…
Preventive Health Behaviors Among Grandmothers Raising Grandchildren
The enhancement of preventive behavior seen among long-term grandparent caregivers does not fully offset the suppression of preventive behavior during the transition into care; support groups should target a range of interventions toward the promotion of healthy behavior among new grandparent caregivers
Genetic Variation in Political Participation
The decision to vote has puzzled scholars for decades. Theoretical models predict little or no variation in participation in large population elections and empirical models have typically accounted for only a relatively small portion of individual-level variance in turnout behavior. However, these models have not considered the hypothesis that part of the variation in voting behavior can be attributed to genetic effects. Matching public voter tur…
Rebellious teens? Genetic and environmental influences on the social attitudes of adolescents
Genetic and environmental influences in social attitudes were investigated in adopted and nonadopted children (N = 654) and their biological and adoptive relatives in the Colorado Adoption Project. Conservatism and religious attitudes were measured in the children annually from ages 12 to 15 and in the parents during the 12-year-old visit. Multivariate genetic model fitting indicated that both conservatism and religious attitudes are strongly inf…
Nonshared environmental influences and personality differences in adult twins
The twin design was used to examine the importance of different experiences of siblings within the family and to identify relations between twins' personality differences and their differential experiences. A sample of 161 monozygotic and 74 dizygotic twin individuals between the ages of 18 and 75 years retrospectively reported on their different experiences when growing up. The Sibling Inventory of Differential Experience (SIDE) was used for the…
Genotype-Environment Covariance for Multiple Phenotypes
A bivariate generalization of the genotype-environment (GE) covariation is presented. This biometrical parameter measures the relation between genotypic influences in one attribute with environmental influences in another attribute. A multivariate procedure for detecting the presence of both univariate and bivariate GE covariation is also described, based on a test of homogeneity of observed variance-covariance matrices in adopted and nonadopted …
Genetic and environmental influences on aggression in 4- to 7-year-old twins
Aggressive behaviors of 38 twin pairs (21 monozygotic [MZ], 17 dizygotic [DZ]) between the ages of 4 and 7 years were assessed through mothers' ratings and observations in their homes. An observation checklist was developed in which mothers were asked to observe and report each child's specific aggressive behaviors for a total of 6 hours spread over 3 days. In particular the observations focused on the following behaviors: rejection, destructiven…
