The current study sought to investigate whether word properties can facilitate the identification of developmental language disorder (DLD) in sequential bilinguals by analyzing properties in nouns and verbs in L2 spontaneous speech as potential DLD markers. Measures of semantic (imageability, concreteness), lexical (frequency, age of acquisition)…

Language is conventional because word meanings are shared among different people. The present study examined Chinese infants' understanding of the language convention that different people should generalize words in the same way. Thirteen-month-old Mandarin-speaking Chinese infants repeatedly viewed a speaker providing a novel label for a target…

Constructivist approaches to language acquisition predict that form-function mappings are derived from distributional patterns in the input, and their contextual embedding. This requires a detailed analysis of the input, and the integration of information from different contingencies. Regarding the acquisition of morphology, it is shown which…

This study investigates Mandarin-speaking children's knowledge of event semantics in interpreting spatial modifiers with "zai" 'at' after a posture verb or before a placement verb. The event-semantic principles investigated include subevent modification (Parsons, 1990) and aspect shift (Fong, 1997). We conducted an experimental study…

This study evaluates the effects of Age of Exposure to English (AoEE) and Current Input/Output on language performance in a cross-sectional sample of Spanish-English bilingual children. First- (N = 586) and third-graders (N = 298) who spanned a wide range of bilingual language experience participated. Parents and teachers provided information…

Pronoun reversal, the use of "you" for self-reference and "I" for an addressee, has often been associated with Autism Spectrum Disorder (ASD) and impaired language. However, recent case studies have shown the phenomenon also to occur in typically developing and even precocious talkers. This study examines longitudinal corpus data from two…

We investigate how Tamil- and Dutch-speaking adults and four- to five-year-old children use caused posture verbs ("lay/stand a bottle on a table") to label placement events in which objects are oriented vertically or horizontally. Tamil caused posture verbs consist of morphemes that individually label the causal and result subevents ("nikka…

The present study determined whether parenting style, defined by control strategies varying in power-assertion mediated the established relation between maternal language usage (grammar and semantics) and child language (grammar, semantics and pragmatics) during toddlerhood (n = 60). Based upon their use of control strategies mothers were…

Considers children's understanding and use of contrast in language, including discussion of the role contrast plays in adult speech, the kinds of contrast commonly exemplified, and possible tests for sameness or difference of meaning. (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)

A study determined what types of speech act five- to 13-year-olds and adults would define as "promising." Results indicate that children could distinguish between "promising" and "predicting" in terms of the speaker's responsibility for the outcome. (Author/CB)

Discusses information theory and the notions of uncertainty and semantic choice in child language. (AM)

Gives a syntactic, semantic, pragmatic, and discourse structure analysis of mothers' speech to children of 1;0, 1;8, 2;3, and 5;0 years, showing that the age of the child to whom mothers were speaking could be predicted very accurately from her speech. The changes in mothers' speech are responses to concurrent changes in children's language…

Analyses of longitudinal speech data collected from two children indicated that children rapidly acquire count/mass noun distinctions. (Author/CB)

Analysis of the use of the connective "but" by 3- to 9-year-olds indicated that all most commonly used the word to signal semantic relationships and for pragmatic functions. Younger children most frequently used "but" when causal or precausal relationships existed, and older children used "but" more to encode complex contrast. (Author/CB)
