Relationship between heart rate indices of the orienting response and birth weight in normal full-term newborns.

abstract：:To extend a previous finding that 6-month-old infants categorized low-pass filtered infant-directed (ID) utterances, we examined a) 6-month-old infants' categorization of more naturalistic, unfiltered ID utterances and b) the developmental progression of ID-speech categorization. In Experiment 1, 6-month-olds heard se...
