Purpose: This study examines the influence of lexical and phonological factors on expressive lexicon size in 40 French-speaking children tested longitudinally from 22 to 48 months. The factors include those based on the lexical and phonological properties of words in the children's lexicons (phonetic complexity, word length, neighborhood density…

Background: Little empirical research examines the process in which home literacy environment (HLE) in toddlerhood is associated with preschoolers' vocabulary and decoding skills using a large-scale dataset. Objective: The purposes of the current study were to (a) examine the differential effect of HLE in toddlerhood on preschoolers' vocabulary…

Because dual language learners are the fastest--growing segment of the U.S. student population--and the majority speak Spanish as a first language--the new generation of SLPs must have comprehensive knowledge of how to work effectively with bilingual speakers. That's what they'll get in the second edition of this book, an ideal graduate-level text…

Toddlers' and preschoolers' knowledge of the phonological forms of words was tested in Spanish-learning, Catalan-learning, and bilingual children. These populations are of particular interest because of differences in the Spanish and Catalan vowel systems: Catalan has two vowels in a phonetic region where Spanish has only one. The proximity of the…

This study examined the effect of lexical aspect and phonology on regular past-tense production. Data are presented from a group of 31 children, mean age 33 months, with typical language development. A case study of a 50-month-old child with Specific Language Impairment (SLI) is also presented. Children imitated sentence pairs that included an…

This study investigated developmental patterns of acquisition of the unrounded U.S. English vowels, by following 6 normally developing children from 22 to 30 months of age. Three classes of production errors were identified: intertrial production variability, context-sensitive substitutions, and context-free systematic substitution patterns.…

Naturalistic speech samples of 29 3-year olds diagnosed with specific expressive language delay were compared to 19 age-matched peers in order to determine their improvement in phonological skills since age two. Results revealed no significant differences in number of vocalizations, although there were differences in phonetic inventories,…

Reviews the research in the area of Spanish language acquisition, with special emphasis on acquisition by Mexican-American children ages two to five. Presents a tentative course of development in phonology, morphology, and syntax. Discusses implications for early childhood education and other areas in need of further research. (Author/GLR)

Describes the phoneme repertoires and phonological error patterns used by Cantonese-speaking children, as well as a longitudinal study of tone acquisition by four children. The developmental error patterns used by more than 10% of children are reported as common in other languages. Specific rules associated with Cantonese phonology are identified.…

Toddlers in the lowest 10th percentile for lexical production were compared with age- and language-matched controls on measures of phonetic complexity, lexical development, and grammatical complexity. Results indicate an overlap between phonology, lexicon, and grammar and suggest the importance of true consonant production for lexical development.…
