Background: Understanding memory retention in children with developmental language disorder (DLD) compared with their typically developing (TD) peers enhances our knowledge of memory processes. Aims: To examine long-term memory consolidation of a declarative object-location task and a procedural symbol-writing task, along with grammatical and…

Background and aims: Current evidence shows that children with developmental language disorder (DLD) benefit from spaced retrieval during word learning activities. Word recall is quite good relative to recall with alternative word learning procedures. However, recall on an absolute basis can be improved further; many studies report that fewer than…

Action video-games (AVGs) could improve reading efficiency, enhancing not only visual attention but also phonological processing. Here we tested the AVG effects upon three consolidated language-based predictors of reading development in a sample of 79 pre-readers at-risk and 41 non-at-risk for developmental dyslexia. At-risk children were impaired…

Variation in the "FMR1" gene may affect aspects of cognition, such as executive function and memory. Environmental factors, such as stress, may also negatively impact cognitive functioning. Participants included 1,053 mothers of children with and without developmental disabilities. Participants completed self-report measures of executive…

Purpose: The nature of the relationship between memory and sentence comprehension in school-age children with developmental language disorder (DLD) has been unclear. We present a novel perspective that highlights the relational influences of fluid intelligence, controlled attention, working memory (WM), and long-term memory (LTM) on sentence…

Purpose: The storage-only deficit and joint mechanism deficit hypotheses are 2 possible explanations of the verbal working memory (vWM) storage capacity limitation of school-age children with developmental language disorder (DLD). We assessed the merits of each hypothesis in a large group of children with DLD and a group of same-age typically…

Procedural memory functioning in developmental language disorder (DLD) has largely been investigated by examining implicit sequence learning by the manual motor system. This study examined whether poor sequence learning in DLD is present in the oculomotor domain. Twenty children with DLD and 20 age-matched typically developing (TD) children were…

Background and aims: Previous research into word learning in children with developmental language disorder (DLD) indicates that the learning of word forms and meanings, rather than form-referent links, is problematic. This difficulty appears to arise with impaired encoding, while retention of word knowledge remains intact. Evidence also suggests…

Background: A growing body of work shows that children with developmental language disorder (DLD) perform poorly on statistical word learning (SWL) tasks, consistent with the predictions of the Procedural Deficit Hypothesis that predicts that procedural memory is impaired in DLD. To date, however, SWL performance has not been compared across…

Background: Children with developmental language disorder (DLD) have deficits in verbal and non-verbal processing relative to typically developing (TD) peers, potentially reflecting difficulties in working memory, processing speed and inhibition of interference. We examined working memory in children with DLD using the…

Purpose: This study examined procedural and declarative learning and consolidation abilities in adults with developmental language disorder (DLD) relative to their typical language (TD) peers. Method: A total of 100 young adults (age 18-24 years) with (n = 21) and without (n = 79) DLD participated across two sites. Performance measures on a…

Some theories of Developmental Language Disorder (DLD) explain the linguistic deficits observed in terms of limitations in non-linguistic cognitive systems such as working memory. The goal of this research is to clarify the relationship between working memory and the processing of complex sentences by exploring the performance of 28…

Developmental dyscalculia (DD) affects 2-6% of the population. Yet, a readily accessible list of potential interventions for DD is not available or can be easily found by educators. With a large percentage of the population afflicted with DD, educators should be made aware of what supportive approaches are available. The purpose of this study was…

This study (a) examines the role of cognitive abilities, age and vocabulary in the development of definitions and (b) compares the development of definitions (in content and form) in children with and without Developmental Language Disorder (DLD). Definitions have been extensively studied in (non-)impaired populations. So far, no studies have…

The research studies presented in this special issue rest on two assumptions: firstly, that limitations in verbal short-term memory and verbal working memory (vSTM/WM) capacity are likely to be related to impairments in syntax, and secondly that this relationship is likely to be causal, with impairments in vSTM/WM causing impairments in syntax. In…
