Abstract:
:The stability of children's skin conductance level during baselines (SCL-B) and SCL reactivity (SCL-R) were examined longitudinally. During two laboratory sessions (T1 and T2), 2 years apart, children participated in procedures during which they were exposed to two stressors namely exposure to an audiotaped conflict between two adults, and a problem solving task. Children ranged in age between 6 and 13 years at T1. Measures of SCL-B and SCL-R during the two stressors were obtained. Findings illustrated the temporal stability of SCL-B and SCL-R to the star-tracing task over 2 years. Results also indicated stability in SCL-R to the two stressors (argument and problem-solving) examined within the same session at either T1 or T2. These results support the proposition that SCL-B and SCL-R constitute stable individual differences at the ages examined, and build on the scant longitudinal literature on psychophysiological development in children.
