Did you say my name? Congruency of 12-month-old infants' behavioral and cardiac responses to name.

ABSTRACT: Reduced orienting to name is an early behavioral risk marker for neurodevelopmental disorders. However, individual instances of infants' behavioral responses to name are limited in both reliability and predictive validity. Physiological responses such as heart rate (HR) deceleration may serve as more sensitive metrics than behavioral methods. As a first step toward validating HR deceleration as a candidate psychophysiological measure of name processing, we examined the congruency of behavioral and cardiac responses to name in 12-month-old typically developing infants. Infants exhibited greater median HR deceleration and spent a larger proportion of time in HR deceleration when they behaviorally oriented to their names than when they failed to do so; however, maximum HR deceleration was not
