Children exhibiting a referential orientation seem more likely to acquire new object names than nonreferentially oriented children. Also, children's selection of words may be influenced by the phonological structure of the words. (Author/RH)

Three experiments found that (1) nine-month olds listened more to two-syllable words with strong-weak stress patterns than weak-strong stress patterns; (2) six-month olds showed no preferences for stress patterns; and (3) nine-month olds showed preferences for strong-weak over weak-strong stress patterns in speech sounds passed through a low-pass…

Examines whether vocal exchanges between preverbal infants and their mothers show characteristics similar to those found to be typical of conversational exchanges between competent adult speakers. (HOD)

Five studies examined the contributions of syllable-ordering and rhythmic properties of syllable strings to 6- and 9-month-old infants' speech segmentation. Results indicate that the capacity for integrating multiple sources of information in speech perception emerges between 6 and 9 months, in rough synchrony with the emergence of integration in…

Examined infants' tendency, from a few days to nine months of age, to prefer infant-directed over adult-directed speech. Results suggest that exaggerated pitch contours that characterize infant-directed speech may become salient communicative signals for infants through language-rich, interactive experiences with caretakers and increased…

Patterns of speech from lower socioeconomic status mothers to their infants were analyzed to determine correlations with infant risk of mental retardation. Measures of maternal language included sentence form, amount of speech, and syntactic complexity. The proportion of imperatives was positively correlated with risk status and negatively…
