Reviews some of the principal phenomena that have been found to characterize the acquisition of word meaning during the first two years of life, and proposes a theoretical framework which can be used to interpret these phenomena. (MP)

A brief history of the study of language acquisition is followed by a detailed discussion of two subareas: metalinguistic thinking and the development of literacy. (MP)

Two experiments were conducted to test Chinese children's comprehension of count-and mass-classifiers. Participants were Chinese-speaking children ages 3 thru 8, plus 16 adults. Results cohere with the linguistic analysis that the count-mass distinction is relevant in Chinese grammar. Results also cohere with the current theory in cognitive…

Reports on experiments investigating children's knowledge of the constraints on ellipsis constructions in English, focusing on subtle contrasts between verb phrase ellipsis (VPE) and VP-anaphora (VPA). Results from parallel experiments employing the same stimuli but with different methodologies show that young children can correctly distinguish…

A review of studies on children's syntactic development in Spanish focused on their use of subordinate clauses within complex sentences. Results suggested that, although they made some developmental gains from 2 years of age, 10-year-olds had not acquired the full range of semantic and syntactic expression characteristic of adult use of…

Examines phonetic variation in multisyllable babbling of infants from 7 to 11 months of age. The investigation was to verify assumptions that, in infant vocal development, there is a systematic increase in the phonetic variation of these babbles, and separate stages of repetitive and nonrepetitive babbling are posited.

Challenges the position of Clark (1988) that no two forms in a language can mean the same thing. An alternative is offered that draws on the drive towards the adult system, development of nonlinguistic concepts, acquisition of language in context, and use of a cooperative principle in conversational exchanges.

Children's ability to distinguish between the text (what was said) and the intentional structure (what was meant) was interrogated by means of verbatim and paraphrase questions in two types of discourse: narratives and nursery rhymes. (Author/VWL)

Two studies of children's conversational language abilities are reported. In the first, mean length of utterance (MLU) and lexical diversity (D) were examined in a group of typically developing Cantonese-speaking children in Hong Kong. Regression analyses indicated a significant linear relationship between MLU and age (R = .44) and a significant…

Current views on the acquisition of PRO can roughly be divided into two areas: lexical and syntactic accounts. We present data on one verb, "decide," that yields data that not only differs from the data for other similar verbs with the same children, but does not lend itself easily to either type of account. Data from a sentence elicitation task…

This study examines 16-month-olds' understanding of word order and inflectional properties of familiar nouns and verbs. Infants preferred grammatical sentences over ungrammatical sentences when the ungrammaticality was cued by both misplaced inflection and word order reversal of nouns and verbs. Infants were also sensitive to inflection alone as a…

A group of preschool-aged children with specific language impairment (SLI), a group of typically developing children matched for age (TD-A), and a group of younger typically developing children matched for mean length of utterance (TD-MLU) were presented with novel verbs in contexts that required them to inflect with past tense "-ed."…

Parents of children with suspected Childhood Apraxia of Speech (sCAS, n = 20), Specific Language Impairment (SLI, n = 20), and typically developing speech and language skills (TD, n = 20) participated in this study, which aimed to quantify and compare reports of early vocal development. Via a questionnaire, parents reported on their child's early…

Purpose: The ontogeny of mandibular control is important for understanding the general neurophysiologic development for speech and alimentary behaviors. Prior investigations suggest that mandibular control is organized distinctively across speech and nonspeech tasks in 15-month-olds and adults and that, with development, these extant forms of…

This study introduces a typological model of the "conceptual language-specific approach" to the L2 research on the acquisition of tense-aspect. The model is based on the typological notion of prominence, classifying languages into tense-prominent and aspect-prominent (Bhat 1999) and the L1 research proposal that language-specific…
