Ten four-year-old boys explained how a toy worked to "high varbal" and "low verbal" two-year-old boys. Results showed that the listener's linguistic ability and conversational responsiveness influenced preschoolers' speech modifications. (Author/JMB)

Tests the hypothesis that the extent to which the durations of pauses (silences within the utterances of a single speaker) and switching pauses (silences between the utterances of 2 speakers) in the speech of children in conversation become similar (i.e., exhibit conversational congruence) is positively related to age. (BRT)

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)

Samples of spontaneous speech were collected from 20 English and 20 German preschool children and their mothers. The children's frequency of use of various tenses was compared at different age levels within each language, across languages, and with their mothers' frequency of tense usage in speech to the children. (Author/JMB)

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)

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…

Findings suggest that (1) dyslexia is more prevalent in the United States than in Italy, (2) reading disabilities are strongly associated with disorders of verbal processing in both countries (although some American dyslexics also show visual-motor deficits), and (3) there is a greater dissociation between reading comprehension and decoding in…

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…
