Abstract

We examined trajectories of skin conductance level (SCL) during baselines and two tasks across middle and late childhood through growth modeling. We also assessed the role of individual differences including child sex, race, and externalizing behavior problems (delinquency, anger, and aggression) in defining these trajectories. At T1, 128 girls and 123 boys (Mean age 8.23 yrs; SD=0.73) participated; 64% were European-American and 36% were African-American. Families participated in 2nd and 3rd study waves with a one-year lag between each wave. Mothers and children reported on child externalizing problems. Addressing notable gaps in knowledge, findings demonstrate varying trajectories of SCL over time based on the child's behavior problems, race, and sex, and are of importance for a better understanding of developmental psychopathology processes.
