Young children with developmental disabilities (DD) exhibit a range of strengths and weaknesses in cognitive, language, and adaptive skills. Identifying individual patterns of abilities across these domains is important for informing interventions. This study examines how 129 toddlers with significant developmental delays and less than 10 spoken…

Purpose: Late talkers (LTs) are a group of children who exhibit delays in language development without a known cause. Although a hallmark of LTs is a reduced expressive vocabulary, little is known about LTs' processing of semantic relations among words in their emerging vocabularies. This study uses an eye-tracking task to compare 2-year-old LTs'…

This study investigates the influence of semantic maturation on early lexical development by examining the impact of contextual diversity--known to influence semantic development--on word promotion from receptive to productive vocabularies (i.e., comprehension-expression gap). Study 1 compares the vocabularies of 3685 American-English-speaking…

Previous studies report that children use color words haphazardly before acquiring conventional, adult-like meanings. The most common explanation for this is that children do not abstract color as a domain of linguistic meaning until several months after they begin producing color words, resulting in a stage during which they produce but do not…

Purpose: The purpose of this study was to improve standardized language assessments among bilingual toddlers by investigating and removing the effects of bias due to unfamiliarity with cultural norms or a distributed language system. Method: The Expressive and Receptive Bayley-III language scales were adapted for use in a multilingual country…

The ELO-L (Évaluation du langage oral chez l'enfant libanais) is the first norm-referenced language-screening test in Lebanon. It is an adaptation of the ELO, a French language-screening test. The ELO-L was normed on 1,718 children aged three to eight years and divided into eight age groups with a minimum of 100 participants in each group. It is…

To what extent do toddlers have shared vocabularies? We examined CDI data collected from 14,607 infants and toddlers in five countries and measured the amount of variability between individual lexicons during development for both comprehension and production. Early lexicons are highly overlapping. However, beyond 100 words, toddlers share more…

A body of studies, which are mostly based on parental reports, have documented gender differences in early language proficiency, and girls tend to outperform boys in both language production and language comprehension. In this study, staff in Norwegian Early Childhood Education and Care institutions observed language comprehension, word…

Research with monolingual children has shown that early efficiency in real-time word recognition predicts later language and cognitive outcomes. In parallel research with young bilingual children, processing ability and vocabulary size are closely related within each language, although not across the two languages. For children in dual-language…

We trained forty German-speaking children aged 1;8-2;0 in their comprehension of UNTER [UNDER]. The target word was presented within semantically organized input in the form of a "narrative" to the experimental group and within "unconnected speech" to the control group. We tested children's learning by asking them to…

This study tested the theory that future poor comprehenders would show modest but pervasive deficits in both language comprehension and production during early childhood as compared with future poor decoders and typical readers. Using an existing database (NICHD ECCRN), fifth-grade students were identified as having poor comprehension skills…

This study examined prior qualitative differences in the process of the emergence of verb use in two sisters when they were each 12 to 24 months of age (the older sister is 2 years and 9 months older than the younger sister). Daily diaries on both children were kept by the mother, who noted emergent structure and vocabulary. Systematic Analysis of…

Offers resolutions to the paradox of infants' ability to abstract patterns over specific items and toddlers' lack of ability to generalize patterns over specific English words/constructions. Argues that contradictions are rooted in differing methodologies and stimuli content. Suggests that the patterns infants extract from linguistic input are not…
