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,…

A study was conducted of the development of consonant clusters in the phonology of a native English-speaking child. His progress was studied over a year and a half period, in three one-month segments. His speech was recorded by tape and transcribed. Techniques used to elicit consonant clusters included real word imitation, imitation of nonsense…

To the question of whether Chomsky's hypothesized Language Acquisition Device (LAD) in young children is an adequate and feasible model of language acquisition, this paper answers that LAD should be reformulated so as to include semantics; that "informant presentation" rather than "text presentation" is responsible for language…

This paper reviews work done since January 1972 in children's language acquisition and development. It is divided into the following sections: (1) a brief summary of descriptive studies of adult and child speech, (2) a review of the results of three types of manipulative studies, and (3) a discussion of J. Gruber's interpretation of early…

Studies of the speech of 11 Yakima Indian children on a reservation in central Washington indicated a number of characteristics which were not found systematically in the speech of non-Indian children. These included differences in phonology; intonation contours; use of direct quotations; story-telling register; language play; availability of…

Three ten-step series of synthetic speech stimuli were constructed: /raem/ to laem/, /raem/ to /waem/, and /laem/ to /yaem/. Within each series, differences consisted of variations in onset frequency and slope of transition in the second or third formant. These stimuli were presented to 5- to 7-year-old children in identification…

This paper studies aspects of the conceptual basis for language acquisition, with a focus on the perceptual-cognitive skills used to assign meanings to words. A first assumption is that the correspondence between adult and child perceptual features allows for early communication. Apparently, in the first year, naming is characterized by…

This paper offers some ideas on the types of behavior that can be considered precursors to language and that also lay the foundations for logic, mathematics, physics, etc. The paper posits the problem of whether a theory of language must be formulated before one can formulate a theory of language acquisition, or whether the reverse is true. The…

This research paper summarizes several experiments in which children's speech volume was compared to the varied background noise against which they spoke. Age was found to be an important factor: 4 1/2-year-olds, as contrasted with 6 1/2-year-olds, failed to adjust their speech to make it audible over noise when talking about complex stimuli.…

Theoretical correspondences between the language and play development of young children and developmental aspects of play and speech are discussed prior to a report of a study comparing categories of cognitive complexity nested within social categories of solitary play and self speech. Participants were 36 preschool boys and girls approximately…
