Purpose: The objective of this study was to compare vocabulary size and composition in 2-year-olds learning Polish or English as measured by the Language Development Survey (LDS; Rescorla, 1989). Method: Participants were 199 Polish toddlers (M = 24.14 months, SD = 0.35) and 422 U.S. toddlers (M = 24.69 months, SD = 0.78). Results: Test-retest…

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: This study reports age 5 morphology and syntax skills in late talkers identified at age 2 (n = 34) and typically developing comparison children (n = 20). Results: The late talkers manifested significant morphological delays at ages 3 and 4 relative to comparison peers. Based on the 14 morphemes analyzed at age 5, the only significant…

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: 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…

For sixty-seven children with ASD (age 1;6 to 5;11), mean Total Vocabulary score on the Language Development Survey (LDS) was 65.3 words; twenty-two children had no reported words; and twenty-one children had 1-49 words. When matched for vocabulary size, children with ASD and children in the LDS normative sample did not differ in semantic category…

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: 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: 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…

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…

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…

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…

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…

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.)
