Toddlers with smaller vocabulary than expected for their age are considered late talkers (LT). This study explored the effects of characteristics of words on vocabulary acquisition of 12- to 24-month-old LT children compared with an age matched (AM) and a vocabulary matched (VM) group of typically developing peers. Using the…

This study investigated the relation between lexical development and the production of prosodic prominence in disyllabic babble and words. Monthly recordings from nine typically developing Belgian-Dutch-speaking infants were analyzed from the onset of babbling until a cumulative vocabulary of 200 words was reached. The differentiation between the…

Purpose: Language and speech are difficult to assess in newly arrived internationally adopted children. The purpose of this study was to determine if assessments completed when toddlers were first adopted could predict language outcomes at age 2. Local norms were used to develop early intervention guidelines that were evaluated against age 2…

Analysis of a complete set of word-forms produced by a one-year-old at the one-word stage found that the data showed little phonetic variability and that phonological development during the period studied (about one year) was qualitatively continuous with subsequent development. (Author/CB)

Similarity neighborhoods for words in young children's lexicons were investigated using three computerized databases. Results revealed that words in five- and seven-year-olds' lexicons have many fewer similar neighbors. (Author/CB)

Develops a psychologically plausible model of the development of word-naming skills in children in order to verify psychological evidence indicating the importance of children's underlying phonological skills as determinants of the ease with which they learn to read. This model is highly successful in learning the pronunciations of single-syllable…

Provides evidence for developmental changes in the composition of the lexicon, reflecting a shift in emphasis from reference, to predication, to grammar. Findings show that the study of qualitative variation in lexical style is confounded by quantitative variation in rate of lexical development. Tables are appended. (Contains 42 references.) (JP)

Examines issues relating to similarity neighborhoods of words in children's lexicons. Young children's receptive vocabularies were analyzed for three-phoneme, four-phoneme and five-phoneme words. The pattern of the original results from Charles-Luce & Luce (1990) was replicated. (18 references) (Author/CK)

Two studies of the innovative semantic distinctions and innovative uses before the acquisition of conventional number classifiers by young Japanese children (aged 5-7 years) are discussed. The findings suggest that lexical acquisition is an intricate process which often requires more than simple mappings of forms onto categories, and that…

A phenomenon called "pragmatic variation" is discussed as a child's individual system of behavior in response to a question the child doesn't understand but realizes that he must verbalize an answer to. (NCR)

Production of the deictic verbs "bring" and "take" was evaluated among 88 normally functioning elementary school children. Results showed that data evaluation procedures greatly influenced conclusions, the second-to-emerge form was easier to learn in a conventional way, and the second term was the proactive stimulus for…

Describes a study done to determine whether the degree of children's familiarity with component words was related to (1) their ability to produce productive patterns as opposed to associative and grouping patterns, and (2) their ability to use broader scope rather than lexically based patterns. (SED)

Examines within an experimental paradigm phonological selection and avoidance patterns of infants and discusses the role of these patterns in early lexical acquisition. (EKN)

This report describes an investigation of the acquisition by children of a symbolic system, specifically English nomenclature--that set of nouns that serves the function of naming, denoting, or referring to objects. The five studies involve nine experiments dealing with one or another of the aspects of this problem. Two questions guided these…
