Despite earlier claims that language abilities are intact in individuals with Williams syndrome (WS), many studies have shown that language development is often delayed and atypical, that is, it develops in line with different cognitive abilities compared to typically developing populations. It is unclear, however, whether general cognitive…

In this study, the relationship between vocabulary and gesture use is examined in children with autism spectrum disorder (ASD) at different language stages. A total of 72 children with ASD between the ages of 3.0 and 8.2 years participated in the study. Gesture use was assessed by using observation-based procedures, while the number of different…

The ability to map similar sounding words to different meanings alone is far from enough for successful speech processing. To overcome variability in the speech signal, young learners must also recognize words across surface variations. Previous studies have shown that infants at 14 months are able to use variations in word-internal cues (i.e.,…

Toddlers from low-income and language-minority immigrant families are at risk for language difficulties due to early disparities in the quality of their home language environment. The present longitudinal study extends previous research by investigating nursery teachers' communicative modalities and functions, and their relations with the…

Conceptualizing numbers as discursive constructs generated in, and for the sake of, communication, we investigated the development of the numerical discourse of Milo, a boy who was 2 years and 8 months old when we first met him and whom we then followed for 18 months. Our analyses of the child's evolving responses to the question "Where is…

This longitudinal study investigated to what extent the acquisition of cognates among bilingual children depends on the degree of cross-language similarity and intensity of exposure to the tested language, and whether children's sensitivity to cognates with different degrees of cross-language similarity changes over time. For three consecutive…

This article describes the European Portuguese MacArthur-Bates Communicative Development Inventories short forms, the first published instruments for the assessment of language development in EP-learning infants and toddlers. Normative data from the EP population are presented, focusing on developmental trends for vocabulary learning, production…

Bilinguals are often not fully monolingual-like in either language. With respect to the lexicon, recent research demonstrates that their naming patterns for common household objects tend to converge on a common pattern for the two languages. The present study investigates the developmental trajectory of naming of common household objects in…

Language acquisition is a process embedded in social routines. Despite considerable attention in research to its social nature, little is known about developmental differences in the relative priority of certain social cues over others during early word learning. Employing an eye-tracking paradigm, we presented 14-month-old infants, 24-month-old…

Toddlers' discrimination of native phonemic contrasts is generally unproblematic. Yet using those native contrasts in word learning and word recognition can be more challenging. In this article, we investigate perceptual versus phonological explanations for asymmetrical patterns found in early word recognition. We systematically investigated the…

This article presents results from a large population-based study of early communicative development in Norwegian children using an adaptation of the MacArthur-Bates Communicative Development Inventories, comprising 6574 children between 8 and 36 months. Data were collected via the Internet. In accordance with similar studies from other languages,…

Recent studies suggest that there appears to be a similar developmental sequence in the understanding of mental states in both internal-state language and in standard theory-of-mind tasks. These findings suggest possible developmental relations between children's ability to talk and think about the mind. Two experiments investigated the concurrent…

The underlying semantic structure of the complete lexicon of four Hebrew-speaking infants at the one-word stage of lexical development was examined. Particular attention was given to the timing of word acquisition and the patterns of identified relationships among words. Three types of interrelationships among early words were explored: (1)…

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…

Investigated Russian children's color-term acquisition, testing one theory of color universals using acquisition order as a basicness measure and determining whether two terms for blue were genuinely basic. Testing on color-term listing, production, and comprehension indicated that color-term acquisition order agreed with the theory. The two blue…
