Abstract: Early assessments of children's physiological functioning are shown to predict subsequentdevelopmental outcomes. However, individual changes that occur in the development ofphysiological systems may be associated with the pattern of change in behavior across time.Thus, we examined change in respiratory sinus arrhythmia (RSA), an index of physiologicalregulation, as a time-varying predictor in order to assess whether RSA change at ages 3, 4, and 5uniquely influenced the trajectory of externalizing behaviors from age 3 to 5. Results indicatedthat only at age 3 was RSA change significantly associated with decreases in externalizingbehaviors over time. RSA change scores at ages 4 and 5 were unrelated to trajectories ofexternalizing behavior, suggesting that the ability to physiologically regulate by age 3 maycontribute to the development of skills that facilitate more control over behavior throughoutpreschool, and therefore may be more strongly associated with the pattern of change inexternalizing behaviors than later physiological regulation.
