This study examines vocabulary growth rates in first and second languages for Spanish-speaking and Cantonese-speaking English language learners from kindergarten through second grade. Growth-modeling results show a within-language effect of concepts about print on vocabulary. Language exposure also had an effect on English vocabulary: earlier…

This paper investigated the predictive ability of expressive vocabulary size and lexical composition at age 2 on later language and literacy skills from ages 3 through 11. Multivariate analysis of covariance was performed to compare 16 language and literacy outcomes between children with large expressive vocabulary size at 24 months (N = 1,073)…

Five experiments examined whether overt repetition (i.e., saying a word aloud) during exposure is critical to the expressive learning of new words. When participants did not engage in overt repetition during exposure, they nevertheless exhibited clear expressive learning, both with and without an accompanying semantics, indicating that overt…

The use of four types of psychological state words (physiological, emotional, desire, and cognitive) during mother-child play sessions at ages 3, 4, and 5 years was examined in 30 children diagnosed with delayed expressive language at 24-31 months and 15 age-matched comparison children with typical development. The children's mean length of…

The investigation longitudinally examined the phonetic skills of Cypriot-Greek children with late onset of expressive vocabulary. The rate of phonological development within short time increments and the identification of possible speech constraints motivating slow development of expressive language were examined. Participants were seven…

Describes a follow-up study of 25 boys who had been diagnosed with Specific Expressive Language Delay (SELD) at 24 to 30 months of age. At three to four years, half of the boys continued to exhibit poor expressive language skills, suggesting that young children diagnosed with SELD are at considerable risk for continuing language problems. (33…

Examines the acquisition of conditional sentences in American Sign Language (which entail the use of both manual signs and grammaticized nonmanual facial expressions) by deaf children. The results indicate that children first acquire manual conditional signs before they employ obligatory grammaticized facial expressions, and also acquire manual…

This follow-up study compares cognitive and language aspects of a group of Italian children ages 4-6 years, who had shown delayed expressive language abilities at 24 months of age (late talkers), with those of a group of children with a history of normal expressive language development (average talkers). Children were given a battery of…

Longitudinally compared the production of syllable shapes in 10-minute spontaneous speech samples of 20 children with expressive specific language impairment (SLI-E) and 15 typically developing (TD) peers from 24 to 36 months of age. Results are discussed. (Author/VWL)

Comparison of language-impaired two- to three-year-olds (N=10) and normal one-year-olds (N=15) matched for expressive language revealed that the language-impaired subjects acquired a greater number of object concepts presented in a no-action condition than the normal children, although language-impaired subjects' extensions of the names to new…

Investigates communicative intent in 31 toddlers who were slow to talk and 32 normally developing toddlers matched on SES, age, and nonverbal cognitive ability. Communicative intent was studied during free play, both with the mother and with an unfamiliar examiner. Late talkers relied more on nonword vocalization, gestures, and gesture/oral…
