Early childhood heart rate does not predict behavior problems at age
Van Hulle, C.A., Corley, R., Zahn-Waxler, C., Kagan, J., & Hewitt,
It has been found in some previous studies that heart rate recorded as early
as age 3 years could predict externalizing behavior at age 11 years.. In
this study, heart rate recorded at ages 14, 20, 24, 36 months and 7 years
was used to predict parental ratings on behavior scales and composites from
the Child Behavior Checklist for subjects participating in the MacArthur
Longitudinal Twin Study. In contrast to those previous findings, in this
sample heart rate did not predict externalizing behavior at age 7.
