This study investigated the extent to which language skills at ages 2 to 4 years could discriminate Hong Kong Chinese poor from adequate readers at age 7. Selected were 41 poor readers (age M = 87.6 months) and 41 adequate readers (age M = 88.3 months). The two groups were matched on age, parents' education levels, and nonverbal intelligence. The…

We found that infant gaze following and pointing predicts subsequent language development. At ages 0 ; 10 or 0 ; 11, infants saw an adult turn to look at an object in an experimental setting. Productive vocabulary was assessed longitudinally through two years of age. Growth curve modeling showed that infants who gaze followed and looked longer at…

Recent accounts of language acquisition propose that the knowledge structures that comprise language develop within a single, unified system that shares computational resources and representations. One implication of this approach is that developmental relations within the system become central to theorizing about language acquisition. Previous…

This study utilized a large sample of two-parent families from low-income rural communities to examine the contributions of father education and vocabulary, during picture book interactions with their infants at 6 months of age, to children's subsequent communication development at 15 months and expressive language development at 36 months. After…

Hannula and Lehtinen (2001, 2005) defined spontaneous focusing on numerosity (SFON) as the tendency to notice the relatively abstract attribute of number despite the presence of other attributes. According to nativists, an innate concept of one to three directs young children's attention to these "intuitive numbers" in everyday situations--even…

Children's sensitivity to the shared, conventional nature of word meanings makes their word learning more efficient and less prone to error. After reviewing the evidence in support of this claim, we suggest that children's earliest appreciation of conventionality might be rooted in limitations in their theory-of-mind skills.

Children with unilateral pre- or perinatal brain injury (BI) show remarkable plasticity for language learning. Previous work highlights the important role that lesion characteristics play in explaining individual variation in plasticity in the language development of children with BI. The current study examines whether the linguistic input that…

Major innovations are becoming available for research in language development and disorders. Among these innovations, recent tools allow naturalistic recording in children's homes and automated analysis to facilitate representative sampling. This study employed all-day recordings during the 2nd year of life in a child exposed to three languages,…

Since norms for vocabulary acquisition in Maltese children do not yet exist, documentation of productive vocabulary acquisition may contribute to establishing a baseline of lexical development. Clinical implications may thus be derived. The current study is a small-scale investigation of the proportions of Maltese and English lexemes in the…

Autism spectrum disorders (ASD) have been gaining attention, partly as an example of unusual developmental trajectories related to early neurobiological differences. The present investigation addressed the process of learning new words to explore mechanisms of language delay and impairment. The sample included 21 typically developing toddlers…

Forty toddlers aged 20 to 24 months were presented with 32 pairs of images with the auditory stimulus Look followed by the name of the target image (e.g. "Look...tree") in an intermodal preferential looking (IPL) paradigm. The same series of 16 items was presented first with one image as target and then with the other member of the pair as target.…

Purpose: This study presents evidence that gesture is a means to understanding the semantic representations of toddlers. Method: The data were part of a study of toddlers' word learning conducted by N. C. Capone and K. K. McGregor (2005). The object function probe from that study was administered after 1 exposure and after 3 exposures to objects.…

Effects of object-name contiguity on word production were examined in 1 1/2- to 2-yr-old children. Two objects and two spoken names were presented in each of three experiments. Each object was the referent of 1 spoken name. An object was presented either together with its spoken name (modeling trial) or alone (test trial). Modeling trials and test…

Background: Children with Down's syndrome seem to show a preference for the use of gestural rather than vocal productions during the first stages of language development. This "gestural advantage" could actually be due to a developmental strategy used to compensate the difficulties in verbal production that are typical of language…

When presented with a pair of objects, one familiar and one unfamiliar, and asked to select the referent of a novel word, children reliably demonstrate the disambiguation effect and select the unfamiliar object. The current study investigated two competing word learning accounts of this effect: a pragmatic account and a word learning principles…
