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.

This study describes the language and literacy skills of 11-year-olds attending a mainstream school in an area of social and economic disadvantage. The proportion of these young people experiencing difficulties in decoding and reading comprehension was identified and the relationship between spoken language skills and reading comprehension…

Purpose: Onset of canonical babbling by 10 months of age is surprisingly robust in infancy, suggesting that there must be deep biological forces that keep the development of this key vocal capability on course. This study further evaluated the robustness of canonical babbling and other aspects of prelinguistic vocal development. Method:…

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)

Examination of the relationship between linguistic forms and the functions they serve in one- to two-year-olds' (N=6) early talk about agentivity and control found that the subjects systematically employed different self reference forms to mark distinct perspectives on agency. 34 references.

Examined whether there was negative evidence in adult reformulations of erroneous child utterances, and if so, whether children made use of that evidence. Findings show that adults reformulate erroneous utterances often enough for learning to occur. Children can detect differences between their own utterance and the adult reformulation and make…

Study of how the verbal component of "babytalk" affected three-month-olds' (N=40) vocal qualities suggested that conversational turn-taking facilitated a speak-listen pattern of infant vocalizations and indicated that what adults "say" to infants influences what infants "say" in response.

This article compares children's productions of wh-questions such as "who?" or "what?". Data were gathered using the technique of elicited production. (26 references) (JL)

Two studies of the unintelligible speech of developmentally delayed children found that more intelligible child speech was found in routine than in nonroutine situations and that extracted utterances were more intelligible under context-information-present conditions. (35 references) (Author/CB)

The nature and origin of the human capacity for acquiring language is not yet fully understood. Here we uncover early roots of this capacity by demonstrating that humans are born with a preference for listening to speech. Human neonates adjusted their high amplitude sucking to preferentially listen to speech, compared with complex non-speech…

An overview of the babbling stage in child language acquisition, which occurs normally at age six months to one year, looks at research on this period. The babbling stage is preceded by arbitrary infant vocalization and is succeeded by production of simple but recognizable words. Babbling represents a period of increasing pattern and articulatory…

Two theories of speech appear to parallel each other closely, though one (E. Nuttall) is concerned mainly with speech from a functional perspective, and the other (F. Williams and R. Naremore) presents a developmental hierarchy of language form and function. Nuttall suggests there are two main origins of speech: sounds of discomfort (cries,…

An investigation looked at the relationship between control and coreference in three- to eight-year-olds' (N=81) performance of an act-out task. Results replicated previous findings that demonstrated five developmental stages (involving subject-oriented, object-oriented, mixed subject-object, and adult approaches) in chidren's interpretation of…

The study investigates the development of English multiword negation, in particular the negation of zero marked verbs (e.g. "no sleep", "not see", "can't reach") from a usage-based perspective. The data was taken from a dense database consisting of the speech of an English-speaking child (Brian) aged 2;3-3;4 (MLU 2.05-3.1) and his mother. The…

The evidence on the acquisition of intonation by children is reviewed. Reports on the early use of pitch contours fall into two categories, imitational and differential intonation. While imitational intonation is based on mimicry of adults, differential intonation involves the acquisition of two or three tunes that contrast in meaning from an…
