Addresses the utility of a noninvasive measure of cardiac vagal tone in predicting developmental outcome among infants at risk for cognitive disabilities. Results suggest that measurement of cardiac vagal tone may provide an important means for assessing risk in birth-stressed populations. (Author/RH)
