Purpose: Previous research into the working, declarative, and procedural memory systems in children with developmental language disorder (DLD) has yielded inconsistent results. The purpose of this research was to profile these memory systems in children with DLD and their typically developing peers. Method: One hundred four 5- to 8-year-old…

Persuasion is an essential social skill. Yet its development and underpinnings are poorly understood. In 2 studies, a total of 167 children aged 3 to 12 years took theory of mind (ToM) tests and participated in unscripted, seminaturalistic persuasive conversations. Children were typically developing (TD) or had deafness or autism spectrum disorder…

We assessed nonword repetition (NWR) skills in 7-9 year-old children with dyslexia (dyslexia-only), developmental language disorder (DLD-only), co-occurring DLD+dyslexia, and typical development (TD) with a norm-referenced and an experimental task. The experimental task manipulated phonemic variability (dissimilarity among consonant phonemes…

We examined the development of 3 executive function (EF) components--inhibition, updating, and task shifting--over time in monolingual and bilingual school-age children. We tested 41 monolingual and 41 simultaneous bilingual typically developing children (ages 8-12) on nonverbal tasks measuring inhibition (the Flanker task), updating (the Corsi…

The development of the ability to categorize speech sounds is often viewed as occurring primarily during infancy via perceptual learning mechanisms. However, a number of studies suggest that even after infancy, children's categories become more categorical and well defined through about age 12. We investigated the cognitive changes that may be…

This study examines the role of a particular kind of linguistic input--talk about the past and future, pretend, and explanations, that is, talk that is decontextualized--in the development of vocabulary, syntax, and narrative skill in typically developing (TD) children and children with pre- or perinatal brain injury (BI). Decontextualized talk…

Background: Children with language impairment (LI) show heterogeneity in development. We tracked children from pre-school to middle childhood to characterize three developmental trajectories: resolving, persisting and emerging LI. Methods: We analyzed data from children identified as having preschool LI, or being at family risk of dyslexia,…

Purpose: Impairments in the social use of language are universal in autism spectrum disorder (ASD), but few standardized measures evaluate communication skills above the level of individual words or sentences. This study evaluated the Expression, Reception, and Recall of Narrative Instrument (ERRNI; Bishop, 2004) to determine its contribution to…

Behavioral investigations of the acquisition of "some" have shown that children favor its logical interpretation ("some and possibly all"). Adults, however, use the pragmatic interpretation ("some but not all") derived by a scalar implicature. Certain experimental manipulations increase children's rates of adult-like…

Temporal proximity is one of the key factors determining whether events in different modalities are integrated into a unified percept. Sensitivity to audiovisual temporal asynchrony has been studied in adults in great detail. However, how such sensitivity matures during childhood is poorly understood. We examined perception of audiovisual temporal…

Background & Aims: The present study examined how phonological and lexical knowledge influences memory in children with specific language impairments (SLI). Previous work showed recall advantages for typical adults and children due to word frequency and phonotactic pattern frequency and a recall disadvantage due to phonological similarity…

Background: Many children with autism spectrum disorders (ASD) struggle to understand familiar words and learn unfamiliar words. We explored the extent to which these problems reflect deficient use of probabilistic gaze in the extra-linguistic context. Method: Thirty children with ASD and 43 with typical development (TD) participated in a spoken…

This study investigated the developmental time course of spoken word recognition in older children using eye tracking to assess how the real-time processing dynamics of word recognition change over development. We found that 9-year-olds were slower to activate the target words and showed more early competition from competitor words than…

This study investigated whether children with language learning disability (LLD) differed from typically-developing peers in their ability to learn meanings of novel words presented during reading. Fifteen 9-11-year-old children with LLD and 15 typically-developing peers read four passages containing 20 nonsense words. Word learning was assessed…

This work has two objectives. First of all, to offer psychometric instruments that help more precisely identify and differentiate children with specific language impairment (SLI) in the educational field and, secondly, to establish profiles of the two cases that illustrate the two current subtypes of SLI: phonologic-syntactic SLI and…
