Purpose: Wide interindividual variability characterizes language development in the general and at-risk populations of up to 3 years of age. We adopted a complex approach that considers multiple aspects of lexical and grammatical skills to identify language profiles in low-risk preterm and full-term children. We also investigated biological and…

Purpose: The purpose of the current study is to develop a valid and reliable screening tool to identify children with risk of developing language difficulties for Estonian-speaking 2- to 3-year-old children. Method: Nine hundred ninety parents of children ages 1;8-3;1 (years;months) filled in the Estonian MacArthur-Bates Communicative Development…

Linguistic contexts provide useful information about verb meanings by narrowing the space of candidate concepts. Intuitively, the more information, the better. For example, "the tall girl is 'fezzing,'" as compared to "the girl is fezzing," provides more information about which event, out of multiple candidate events, is being…

Purpose: The current study used an intervention design to test the hypothesis that parent input sentences with diverse lexical noun phrase (NP) subjects would accelerate growth in children's sentence diversity. Method: Child growth in third person sentence diversity was modeled from 21-30 months (n = 38) in conversational language samples obtained…

The results from a large-scale study on toddlers' language acquisition in European Portuguese are presented. Toddlers' lexical and grammatical competencies were assessed using the MacArthur-Bates Communicative Development Inventory: Words and Sentences. The results, based on 3012 reports completed by parents, indicate an increase in the lexical…

Young children who hear more child-directed speech (CDS) tend to have larger vocabularies later in childhood, but the specific characteristics of CDS underlying this link are currently underspecified. The present study sought to elucidate how the structure of language input boosts learning by investigating whether repetition of object labels in…

Children recruit verb syntax to guide verb interpretation. We asked whether 22-month-olds spontaneously encode information about a particular novel verb's syntactic properties through listening to sentences, retain this information in long-term memory over a filled delay, and retrieve it to guide interpretation upon hearing the same novel verb…

In this follow-up study, we evaluated children's communication development at the ages of 8 ("n" = 50), 18 ("n" = 46), 24 ("n" = 44) and 36 months ("n" = 36) using the Finnish version of the "MacArthur Communicative Developmental Inventories" (MCDI). A sample of children ("n" = 14)…

We examine how attention to animacy information may contribute to children's developing knowledge of language. This research extends beyond prior research in that children were shown dynamic events with novel entities, and were asked not only to comprehend sentences but to use sentence structure to infer the meaning of a new word. In a 4 x 3…

Several studies have demonstrated that children's gender and parental education exert a significant, but not equal, effect on toddler language development at different ages. This study determined the effect of children's gender and parental education on the verbal competence of toddlers between 16 and 30 months. The sample included 953 Slovenian…

This study examined the concurrent validity of the Language Development Survey (LDS), a 310-word parent report screening tool for language delay in toddlers, by testing its associations with the MacArthur-Bates Communicative Development Inventories: Words and Sentences (CDI:WS), a 680-word parent report instrument. Participants were 239 toddlers…
