Fourteen-month-old infants are unable to link minimal pair nonsense words with novel objects (Stager & Werker, 1997). Might an adult's productions in a word learning context support minimal pair word-object association in these infants? We recorded a mother interacting with her 24-month-old son, and with her 5-month-old son, producing nonsense…

This study compared the temporal measurements of stop consonants in 29 three- to six-year-old Mandarin-speaking children and 12 Mandarin-speaking adults. Each participant produced 18 Mandarin disyllabic words which contained six stop consonants /p, p?, t, t?, k, k?/ each followed by three vowels /a, i, u/ at the word-initial position in the first…

This study investigates effects of age on character introductions in the oral narratives of seventy-two monolingual Swedish-speaking four- to six-year-olds, comparing results from the Multilingual Assessment Instrument for Narratives (MAIN; Gagarina "et al.," 2012, 2015), and the Edmonton Narrative Norms Instrument (ENNI; Schneider…

Speech productions of 40 English- and 40 Japanese-speaking children (aged 2-5) were examined and compared with the speech produced by 20 adult speakers (10 speakers per language). Participants were recorded while repeating words that began with "s" and "sh" sounds. Clear language-specific patterns in adults' speech were found,…

Early language development sets the stage for a lifetime of competence in language and literacy. However, the neural mechanisms associated with the relative advantages of early communication success, or the disadvantages of having delayed language development, are not well explored. In this study, 174 elementary school-age children whose parents…

Objectives: To determine whether oral language, working memory, and social anxiety differentiate children with selective mutism (SM), children with anxiety disorders (ANX), and normal controls (NCs) and explore predictors of mutism severity. Method: Children ages 6 to 10 years with SM (n = 44) were compared with children with ANX (n = 28) and NCs…

Examines spontaneous conversations between adults and children. Findings indicate that adults' altered mean length of utterance and type-token ratio were based on their age. Contrary to the researcher's expectations, the adults did not choose their words from the 10,000 most common word types in an age-dependent manner. (Author/CB)

Examines the age at which and the form in which children produce speech acts which commit them to a future action. Results revealed that all of the four- to 11-year-olds produced directive speech acts, but only the older children used the explicit performative verb "promise" to reassure the hearer of their commitment. (Author/CB)

This study examined age differences in the extent to which children infer and use a speaker's interpersonal goal to understand speech acts and to examine age differences in the extent to which children select responses that carry implications appropriate to the speaker's interpersonal goal.

Examines sex differences in vocalizations and play behaviors displayed toward an infant by preschoolers, preadolescents, and adults. Preschoolers showed less interaction than older subjects. Males talked and played less with the baby than did females at all ages; however, among adult subjects, no sex-role effects were found. (Author/RH)

A study of two- to six-year-olds' spontaneous uses of "from" to mark oblique agents showed that, while the two-year-olds produced "from" for agents and "with" for instruments in imitation, older subjects shifted to "by" for agents and kept "from" to mark locative sources. (Author/CB)

This study investigated the influence of the speaker's experience and addressee's developmental level on baby talk characteristics. A total of 240 mothers of only child infants (l-l8 months) or of children 2-3 years old responded to an Infant or Child Series of drawings with an attached list of sentences. Subjects described situations in drawings,…

Examined the distribution of two Hebrew nominal structures in spoken and written texts of two genres produced by 90 native-speaking participants. Written texts were found to be denser than spoken texts lexically and syntactically as measured by a number of novel N-N compounds and denominal adjectives per clause; in older age groups this difference…

Examined how Italian day-care teachers (N=5) spoke to young children and adjusted their language according to age and size of groups. It was found that teachers made both structural and functional modifications of language according to childrens' ages and the size of groups, with group size exerting a greater influence on the features of the…

The study investigated the effectiveness of a pragmatic language function protocol with a sample of 240 normal preschool children, aged 2-5, in a structured setting. The protocol was shown to be used reliably and was sensitive to differences in the mastery of language skills of normal children of different ages. (Author/JDD)
