Children with language disorders have particular difficulty with verbs, but when this difficulty emerges is unknown. We examined syntactic (transitive, intransitive, ditransitive) and semantic (manner, result) features of two-year-olds' verb vocabularies, contrasting late talkers and typically developing children to look for early differences in…

Purpose: Our objective was to replicate previous cross­linguistic findings by comparing Portuguese and U.S. children with respect to (a) effects of language, gender, and age on vocabulary size; (b) lexical composition; and (c) late talking. Method: We used the Language Development Survey (LDS; Rescorla, 1989) with children (18-35 months) learning…

The present study examined the relation between language and social ability in a sample of 268 preschoolers aged 18-35 months. Expressive language was assessed with the Italian adaptation of the Language Development Survey (LDS), and Social Competence was assessed with the Questionnaire on Peer Interactions in the Kindergarten (QPI). Results…

Purpose: The authors tested associations between (a) parent-reported temporary vs. persistent vocabulary delay and (b) parent-reported behavioral/emotional problems in a sample of 5,497 young Dutch children participating in a prospective population-based study. Method: Mothers completed the MacArthur Communicative Development…

Purpose: The authors investigated continuity and discontinuity of vocabulary skills in a population-based cohort in the Netherlands. Method: Mothers of 3,759 children completed the Dutch version of the MacArthur Short Form Vocabulary Checklist (Zink & Lejaegere, 2003) at 18 months and a Dutch translation of the Language Development Survey…

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…

Vocabulary growth from age 2 to 3 years was studied in 28 late talkers, using expressive vocabulary inventories reported bimonthly on the Language Development Survey (LDS). (Author/VWL)

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…

Twelve boys (24-30 months old) with specific expressive language delay (SELD) and with normal development in every other sphere were identified for longitudinal study. Children were videotaped while playing. Analysis using an ordinal play coding scheme revealed strikingly poor pretend play skills. They appeared deficient in either the ability or…

Age 3 follow-up data are presented for sample of 34 toddlers diagnosed between ages of 24 and 31 months with expressive specific language impairment. Late talkers made more rapid progress in lexical development and in descriptive, explanatory, and definitive use of language than in syntactic and morphological language. Toddlers who'd been more…

Comparison of spontaneous language samples of 30 toddlers diagnosed with specific expressive language impairment (SLI) and language samples of typically developing toddlers found the SLI toddlers vocalized significantly less often, had proportionately smaller consonantal and vowel inventories, and used a more restricted and less mature array of…

Two studies are reported demonstrating the reliability, validity, and clinical utility of the Language Development Survey (LDS) as a screening tool for the identification of expressive language delay in toddlers. The LDS test-retest reliability was .97. The LDS also correlated highly with other measures and the LDS identified at-risk group scored…

Expressive language outcomes measured by MLU and the Index of Productive Syntax (IPSyn) at ages 3 and 4 were investigated in 34 late talkers with normal receptive language and in 16 typically developing comparison children matched on age, socioeconomic status, and nonverbal ability. Late talkers made greater gains than comparison children between…

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,…

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)
