Purpose: The Language Development Survey (LDS; Rescorla, 1989) was used to compare Italian and English lexical development. The authors addressed the issue of universal versus language-specific aspects of lexical development by testing language, age, and gender effects on vocabulary scores and by comparing vocabulary composition across languages.…

Purpose: In this study, the authors aimed to compare vocabulary size, lexical composition, and late talking in large samples of Korean and U.S. children ages 18-35 months. Method: Data for 2,191 Korean children (211 children recruited "offline" through preschools, and 1,980 recruited "online" via the Internet) and 274 U.S.…

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…

Purpose: This study examined whether late talkers identified at 24-31 months continued to have weaker language and reading skills at 17 years of age than typically developing peers. Method: Language and reading outcomes at 17 years of age were examined in 26 children identified as late talkers with normal nonverbal ability and normal receptive…

Purpose: The association between language delay and behavior problems in toddlers was examined in 2 studies, 1 conducted in a developmental clinic in New Jersey (Study 1; N = 83) and the other conducted in a developmental clinic in New York (Study 2; N = 103). Method: In both clinics, parents of 18- to 35-month-olds completed the Language…

Language and reading outcomes at 13 years of age were examined in 28 children identified at 24 to 31 months as late talkers, all of whom came from middle--to upper-class socioeconomic status (SES) families and had normal nonverbal ability and age-adequate receptive language at intake. Late talkers were compared with a group of 25 typically…

Data from 278 children (ages 18-35 months) were used to norm the Language Development Survey (LDS) and the Child Behavioral Checklist. Vocabulary scores increased markedly with age, were higher in girls, and were modestly correlated with socioeconomic level. Correlations between LDS scores and checklist problem scores were low. (Contains…

Late talkers with normal receptive language were compared with typically developing peers at ages 3 and 4 on grammatical suppliance during speech samples. At age 4, "late bloomers" did not differ from typically developing children, but late talkers with "continuing delay" differed on several grammatical variables. Findings are discussed in terms…

Language and reading outcomes at 6 to 9 years of age were examined in 34 children who were late talkers as toddlers. Late talkers performed in the average range on most language and reading tasks by age 5 and 6 but were somewhat less skilled than comparison children at ages 8 and 9. (Contains references.)

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…

Two studies examined word frequencies in toddlers' lexicons using the Language Development Survey (LDS). In Study 1, a high degree of consistency in LDS word frequencies was found in the lexicons of 758 24-month-olds. In Study 2, LDS word frequencies in 40 late talkers found both lexicon size and age of subject influenced the degree of consistency…

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,…

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…
