A total of 16 mothers and 16 fathers were recorded in dyadic sessions with their children (eight five year olds, eight two year olds; half boys, half girls) and with an adult. Noise-free questions and declaratives were analyzed for pitch and frequency range. Results suggest that both fundamental frequency and range are significantly influenced by…

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)

In two experiments, preschoolers interpreted a novel count noun applied to an unfamiliar stuffed animal as referring to a basic-level (such as a person or a dog) kind of object rather than to a context (such as a passenger) or a life-phase (such as a puppy) kind of object. (MDM)

Results of four experiments suggest that two-year-olds may be capable of forming inclusion relations when they hear a novel word for an object that already has a familiar name. (PCB)

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…

Two strategies that children use to figure out new word meanings--attention to linguistic form class and the assumption of lexical contrast--were examined. It was found that very young children use both form class and lexical contrast to interpret new words. (PCB)

Examines how conversations between parents and their 2-year-old children change as a function of the number of family members interacting. Results indicate that parental speech to their young children is influenced by the gender of their offspring and the number of family members interacting in the situation. (Author/RH)

Tests the hypothesis that mothers would label objects with adult-basic level terms when talking to other adults, but would label the same objects with child-basic terms when speaking to their young children who were just starting to talk, even though these labels may be very much "incorrect" by adult standards. (Author/RH)

Mothers and fathers of 43 middle-class families were observed interacting separately during a paper-folding task with either their only or middle child in order to assess parental use of evaluation and task-facilitative behaviors with preschoolers. Results indicate that parent behaviors vary with parent gender, child gender, and family…

Reveals that young children acquiring Mandarin Chinese differentiate subject from topic, even though Chinese is a "topic-prominent" language. Data are based on results of a standardized, elicited imitation test of 95 Chinese children in Taiwan. Subjects between 2 years, 6 months and 5 years of age responded to coordinate as well as…

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…

Compares the spelling errors on the Wide Range Achievement Test II made by adults with an apparent autosomal dominant form of dyslexia to those made by their normal adult relatives and by spelling-age matched normal controls using a computerized error evaluation program. (HOD)

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…

Presents evidence from studies on adults' language processing and children's language acquisition that the lexicon is at the core of grammatical generalizations at several levels of representation. Proposes that phonological acquisition might provide the bootstrapping into grammatical generalization in general. Concludes that age-appropriate…
