The few reports on the language skills of children with attention-deficit/hyperactivity disorder (ADHD) offer conflicting evidence on whether they face significant challenges, and if so, whether these challenges are present in all aspects of language. Here, we investigated a sample of Greek-speaking children with ADHD (n = 29) using a structural…

The study's goals were: (a) to examine the influence of postsecondary education (PSE) in the form of academic enrichment courses on the cognitive performance of adults with intellectual disability (ID); (b) to examine their attitudes toward the program. The sample included adults who participate in PSE (N = 21; CA = 26-59) and a control group of…

Purpose: We previously reported evidence of true double dissociation between reading accuracy and reading rate in a large unselected sample of Hebrew-speaking fourth graders and a large clinical sample of adult Hebrew-speakers with dyslexia. The present study aimed to replicate and extend these findings to Arabic, which is structurally similar to…

Purpose: This study investigated the effects of an AR application (Civilisations AR) on EFL learners' oral proficiency in the dimensions of content, fluency, vocabulary, pronunciation, and grammar, as well as their attitudes and perceptions toward AR technology. Design: Utilizing a quasi-experiment, twenty-four EFL learners engaged in a…

Purpose: Aims of this research were (a) to investigate higher order linguistic and cognitive skills of Italian children with cochlear implants (CIs); (b) to correlate them with the comprehension of irony, which has never been systematically studied in this population; and (c) to identify the factors that facilitate the development of this…

This study addresses the question as to what cognitive abilities influence performance on article choice and direct object scrambling in high-functioning Dutch-speaking children with Autism Spectrum Disorder (ASD). Schaeffer (2016/2018) shows that a group of 27 high-functioning Dutch-speaking children with ASD, aged 5-14, overgenerates the…

This study investigates whether number dissimilarities on subject and object DPs facilitate the comprehension of subject- and object-extracted centre-embedded relative clauses in children with Grammatical Specific Language Impairment (G-SLI). We compared the performance of a group of English-speaking children with G-SLI (mean age: 12;11) with that…

The development of spelling skill is an intricate process for children with or at risk of Specific Learning Disabilities and requires targeted interventions. This problem exacerbates in the Greek orthographic system owning to its high complexity. The current study presents a novel spelling intervention program for Greek 3rd graders at risk of…

Background: A fundamental aim of standardized educational assessment is to achieve reliable discrimination between students differing in the knowledge, skills and abilities assessed. However, questions of the purity with which these tests index students' genuine abilities have arisen. Specifically, literacy and numeracy assessments may also engage…

This study investigates the question as to whether and how the linguistic and other cognitive abilities of children with Specific Language Impairment (SLI) differ from those of children with High-Functioning Autism (HFA). To this end, 27 Dutch-speaking elementary-school-age children with SLI, 27 age-matched children with HFA, and a control group…

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,…

Both for the first language (L1) and for all additional languages (L2 or L3), grammatical knowledge plays a vital role in understanding texts (e.g., Grabe, 2005). However, little is known about the development and interaction of grammar and reading comprehension in beginning foreign language learning, especially with respect to children with a…

The present study investigated the role of both cognitive and linguistic predictors in basic arithmetic skills (i.e., addition and subtraction) in 69 first-language (L1) learners and 60 second-language (L2) learners from the second grade of primary schools in the Netherlands. All children were tested on non-verbal intelligence, working memory,…

This study had three main aims. First, we examined to what extent listening comprehension, vocabulary, grammatical skills and verbal short-term memory (VSTM) assessed prior to formal reading instruction explained individual differences in early reading comprehension levels. Second, we examined to what extent the three common component skills,…

The home numeracy environment (i.e., parents' numeracy expectations and activities), is related to early numeracy in young children. As recent studies have shown that both cognitive and linguistic factors play an important role in predicting numeracy development, it may be assumed that rather than the home "numeracy" environment, the…
