A computerized test of preparedness for effortful processing (alerting attention), response to orienting cues (orienting attention), and response to the interference of competing demands (executive attention) was administered to a diverse sample of 249 children (47% female, 4.96 to 7.27 years) to assess developmental properties and sociodemographic(More)
We explored relationships between anxiety and antisocial behavior and autonomic heart rate regulation in a homogenous sample (N = 175) of 15-year-old males. Measures of anxiety and antisocial behavior were obtained at yearly intervals over a period of 4-6 years. Components of heart rate variability associated with postural (sympathetic) and respiratory(More)
We piloted a computer program to train working memory for children with attention problems or hyperactivity who attended an urban public school serving economically disadvantaged neighborhoods. Training was conducted daily for 5 weeks during school hours. Teachers rated children’s behaviors before and after the intervention, and standardized assessments of(More)
Temporal stability, discriminant validity, and factor structure of an array of performance measures of impulsivity was assessed within samples of normal (N = 48) and behaviorally disordered children (N = 88) ages 6-16 (126 M, 10 F; mean age = 10.57 years; SD = 2.13). Using a relatively conservative standard for adequate temporal stability, 31% of the(More)
As part of a larger investigation of very low income families, this study examined the characteristics that differentiated resilient from nonresilient school-age youths, with a focus on self-regulation (e.g., executive function, emotion regulation) skills. Resilience was operationally defined in a robust and comprehensive manner using well-established(More)
OBJECTIVE To elucidate the effects of tricyclic antidepressants on sympathetic and vagal modulation of heart rate variability. METHOD Seventy-five children and adolescents (mean age 10.5 years, SD 2.0) from therapeutic and regular schools underwent challenges of paced breathing and orthostatic postural change, while heart rate was continuously recorded.(More)
OBJECTIVE The purpose of the study was to determine whether a history of physical or sexual abuse is more common in children with borderline personality disorder than in other children evaluated in the same outpatient psychiatric clinic. METHOD The authors contrasted rates of abuse in 44 children diagnosed with borderline personality disorder and in 100(More)
OBJECTIVE To assess the temporal stability of heart rate and to examine its relationship with fighting behavior. METHOD Heart rate at ages 9 through 12 was compared to a composite measure of fighting behavior in three cohorts of low socioeconomic status boys (n = 138; two cohorts of boys who had been rated as having disruptive behavior problems in(More)
Most studies of self-regulation involving children have linked it to specific outcomes within a single domain of adaptive functioning. The authors examined the association of self-regulation with a range of indices of adaptive functioning among 155 youth ages 8-18 years from families with very low income. Controlling for other explanatory variables,(More)
