Language-impaired individuals with autism perform poorly on tests such as non-word repetition that are sensitive clinical markers of specific language impairment (SLI). This has fuelled the theory that language impairment in autism represents a co-morbid SLI. However, the underlying cause of these deficits may be different in each disorder. In a…

Children with developmental dyslexia (DD) may differ from typical readers in aspects other than reading. The notion of a general deficit in the ability to acquire and retain procedural ("how to") knowledge as long-term procedural memory has been proposed. Here, we compared the ability of elementary school children, with and without…

The article introduces learners between two age groups: childhood and adulthood. The aim of the author is to analyse the writing skills of French primary school learners--mostly 14 years old--and to determine which descriptors could be used to assess them. The article begins with a presentation of the learners' characteristics and continues with a…

Word finding difficulties are often seen in children with language difficulties. Their problem is readily observed and has led to investigations of its nature and encouraged attempts at intervention. Semantic errors in their naming suggest that their knowledge of items is poorly developed and that therapies to strengthen it may be effective.…

The purpose of this study was to compare the effects of three video perspectives: point-of-view, scene view, and a combination of point-of-view and scene view on task completion by three young adults with moderate intellectual disability. The comparison was made, using an Adapted Alternating Treatments Design, across three sets of fundamentally…

This study investigates syntax in Autism Spectrum Disorders (ASD), its parallelism with Specific Language Impairment (SLI) and its relation to other aspects of cognition. We focus on (1) 3rd person accusative clitic (ACC3) production, a clinical marker of SLI hypothesized to relate to WM, and (2) 1st person accusative clitic (ACC1) production,…

Prospective teachers (PTs), enrolled in a mathematics methods course, were asked to analyze children's mathematical thinking by viewing videotaped clinical interviews over the course of an entire semester. They were also asked to conduct two of their own interviews with children as the semester progressed. While the type of analysis varied, all of…

The ability of language-impaired children to maintain coherence by using discourse connectives has so far been assessed by quantitative measures. This study is a first attempt to scrutinize the "quality" of connective use in specific language impairment (SLI). The authors investigate whether Russian-speaking children reveal sensitivity…

Navigational and reaching spaces are known to involve different cognitive strategies and brain networks, whose development in humans is still debated. In fact, high-level spatial processing, including allocentric location encoding, is already available to very young children, but navigational strategies are not mature until late childhood. The…

This article examines the acquisition of embedded verb placement in Swedish children, focusing on Neg-V and V-Neg order. It is proposed that a principle of economy of movement creates an overuse of V-Neg order in embedded clauses and that the low frequency of the target-consistent Neg-V order in child-directed speech obstructs children from…

We adapted the semantic fluency task into British Sign Language (BSL). In Study 1, we present data from twenty-two deaf signers aged four to fifteen. We show that the same "cognitive signatures" that characterize this task in spoken languages are also present in deaf children, for example, the semantic clustering of responses. In Study…

The objective of this study was to investigate the perceptual relevance of acoustic differences in vowels produced by 6 children between the ages of 9-13 years old with unilateral cochlear implants. Formant frequencies were estimated for 12 repetitions of vowels /hid/, /hed/, /haed/, /hud/, /hUd/, and /hAd/ produced by the children. The estimated…

In the present study, we investigated genetic and environmental effects on motor impulsivity from childhood to late adolescence using a longitudinal sample of twins from ages 9 to 18 years. Motor impulsivity was assessed using errors of commission (no-go errors) in a visual go/no-go task at 4 time points: ages 9-10, 11-13, 14-15, and 16-18 years.…

Purpose: Continuous performance tasks (CPTs) are used to measure individual differences in sustained attention. Many different stimuli have been used as response targets without consideration of their impact on task performance. Here, we compared CPT performance in typically developing adults and children to assess the role of stimulus processing…

Purpose: In this study, the authors examined the role of syllabic structure in nonword repetition performance in typically developing (TD) children and children with specific language impairment (SLI). Method: Eighteen children with SLI (5;7--6;7 [years;months]) and 18 TD children matched for chronological age were tested on their ability to…
