How do children infer the meaning of a word? Current accounts of word learning assume that children expect a word to map onto exactly one concept whose members form a coherent category. If this assumption was strictly true, children should infer that a homophone, such as "bat," refers to a single superordinate category that encompasses…

Although toddlers in their 2nd year of life generally have phonologically detailed representations of words, a consistent lack of sensitivity to certain kinds of phonological changes has been reported. The origin of these insensitivities is poorly understood, and uncovering their cause is crucial for obtaining a complete picture of early…

Infants start learning words, the building blocks of language, at least by 6 months. To do so, they must be able to extract the phonological form of words from running speech. A rich literature has investigated this process, termed word segmentation. We addressed the fundamental question of how infants of different ages segment words from their…

This article investigates the relationship between third person singular present tense agreement morphemes, copula "is" and verb-"s", at 2;00 and 2;03. Language samples from 60 children at 2;00 were analyzed for the productivity of copula "is" as measured by the number of different morphemes preceding "is"…

Purpose: This longitudinal study examined the development of prelinguistic skills and the continuity of communication and language from the prelinguistic stage to school age. Method: Prelinguistic communication of 427 Finnish children was followed repeatedly from 6 to 18 months of age (n = 203-322 at ages 6, 9, 12, 15, and 18 months), and its…

Young children are slow to master conventional intonation patterns in their "yes/no" questions, which may stem from imperfect understanding of the links between terminal pitch contours and pragmatic intentions. In Experiment 1, five to ten-year-old children and adults were required to judge utterances as questions or statements on the…

Being able to communicate one's wants and needs is an essential step in typical language development. However, children with diagnosed language delays, which constitute approximately 5-10% of children under three years, may reach this step later than typically developing children. According to Rossetti (2001), communication skills are the most…

Large gaps in cognition and language on the Bayley-III between the top and bottom household wealth quartiles in 1,330 children aged 6-42 months in a representative sample of low- and middle-income families in Bogota were previously shown. Maternal education and the home environment mediated these wealth effects, whereas height-for-age mediated a…

Infants in low-resource settings are at heightened risk for compromised cognitive development due to a multitude of environmental insults in their surroundings. However, the onset of adverse outcomes and trajectory of cognitive development in these settings is not well understood. The aims of the present study were to adapt the Mullen Scales of…

The aim of this study was to develop a measurement approach to assess the learning opportunities provided by parents to their young children with autism spectrum disorder during a free play task and to examine the relationship between learning opportunities and child performance on measures of cognition, autism spectrum disorder symptoms, and…

Everyday activities are replete with contextual cues for infants to exploit in the service of learning words. Nelson's (1985) script theory guided the hypothesis that infants participate in a set of predictable activities over the course of a day that provide them with opportunities to hear unique language functions and forms. Mothers and their…

Based on longitudinal data (n = 338) from the German National Educational Panel Study (NEPS) competence development (mathematics and language) of three groups with different mathematical preconditions (+/- 1 SD) were compared between age 4 to 10. Groups were composed by first measurement of mathematical achievement in pre-school age (5/6 years).…

This paper draws on observational studies of three young children in order to demonstrate firstly, their intrinsic motivation to explore systematically through repeated patterns of action or 'schemas'; secondly, how those repeated actions appear and are explored in their emerging language demonstrating their increasing construction of and…

Over the years, persistently low achievement levels have led scholars to question whether reading skill development is different for deaf readers. Research findings suggest that in order for deaf students to become proficient readers, they must master the same fundamental abilities that are well established for hearing learners, regardless of the…

New approaches to support the early learning for young Indigenous children are important to government policies across Australia. This study explores whether the Abecedarian Approach Australia (3a) intervention, with strong cultural adaptations, can boost young Aboriginal children's early language and learning skills, prior to preschool.…
