It has long been recognized that there is a natural dependence between theories of knowledge representation and theories of knowledge acquisition, with the idea that the right knowledge representation enables acquisition to happen as reliably as it does. Given this, a reasonable criterion for a theory of knowledge representation is that it be…

Sought to verify research findings that suggest there may be a U-shaped developmental trajectory for final syllable lengthening (FSL). Attempted to determine whether vocal maturity and deafness influence FSL . Eight normally hearing infants and eight deaf infants were examined at three levels of prelinguistic vocal development. (Author/VWL)

Describes vocalizations of five 13-month-old infants. Data are reported on syllable shape, vowel-like and consonant-like production in context and time, periodic utterances, complex babbling sequences, recurrent phonetic forms, fundamental frequency, and intonation types. Results are consistent with data from other studies and support theory of…

An analysis was made of the correspondence between intonation and the larger and smaller movements accompanying two-syllable and longer utterances. Synchrony between peaks of intonation and movement pattern was found and is used to argue for a performative basis for early two-word productions. (Author/EJS)

Revised version of a paper presented at the 1971 summer meeting of the Linguistic Society of America at Buffalo, New York. Research supported in part by a National Science Foundation grant made to the Phonology Laboratory, University of California, Berkeley. (VM)

The role of a strategy of reduplication in phonological acquisition and behavior was examined in terms of: (1) the relationship between adoption of this strategy and failure to produce nonreduplicated multisyllabic forms and final consonants, and (2) the role of reduplication in production constraints. (Author/AM)

Looks at phonological development in lexical terms and extends the method of Ferguson and Farwell to consideration of syllables within words. The research is directed toward the question of whether children acqure a sound system by following "universal" orders of acquistion or by developing distinct strategies. (EJS)

This examination focuses on the idea that child language acquisition is constrained by the same principles that have been found to hold on syllable structure across languages. First, a recently-proposed constraint on syllable structure, the Sonority Cycle, is outlined, and the way that it accounts for syllabic structure across languages is…

A study of the utterances of young children, aged 7 to 22 months, is described. These utterances, varying in length from one to 17 syllables, contain only suprasegmental information because the verbal content was incomprehensible to hearers who were not acquainted with the child and the situation in which the utterances occured. In the corpus,…

A preliminary study dealt with the ways in which children between six and seven years of age organize spoken language, specifically aspects of the temporal and segmental structure of polysyllabic English words containing the syllable C/jul/ (e.g., pediculous). (Author/SW)

Current opinion regarding the nature of the young child's representation of two or more languages is that there is one system during the earliest stages of development. This paper explores theoretical and methodological difficulties underlying this issue. Theoretically, it is questioned what is being claimed about the child's cognitive capacities…

Examines different approaches to prosodic acquisition: Gerken's S(W) production template; Fikkert's and Archibald's theories of stress acquisition and Demuth and Fee's prosodic hierarchy account. Results reveal that current approaches cannot account for findings in the data such as the increased preservation of final over nonfinal unstressed…

Two studies examined children's perceptual biases in extracting or identifying words from the stream of speech. In one study, evidence for the salience of stressed and final syllables was found. Young children less frequently omitted those syllables from their productions and produced unstressed and nonfinal syllables less accurately. A second…

Describes a study of young children's production of novel words serving as names of objects and actions, which were matched according to consonant and syllable structure. On each measure, accuarate production of new consonants was greater for the object words, possibly because action words have greater semantic complexity than object words. (SED)

A report of research on phonology consists of two parts. The first examines the direction in which syllables are "built"--whether the segment or the syllable came first. The first part looks at the effects that different forms of syllabification have on syllable structure, and explores which syllable structure accounts for most…
