Direct linkAtmaca, Furkan; Baloglu, Mustafa – Gifted Child Quarterly, 2022
We compared the Wechsler scores of individuals with twice-exceptionality (2e) and giftedness using a three-level Bayesian meta-analysis. Ninety-five effect sizes were calculated from 15 studies (n = 2,106). Results show that individuals with 2e who have learning disabilities perform lower than individuals with giftedness in Full-Scale Intelligence…

Peer reviewedDe Visscher, Alice; Noël, Marie-Pascale; Pesenti, Mauro; Dormal, Valérie – Journal of Learning Disabilities, 2018
Numerous studies have tried to identify the core deficit of developmental dyscalculia (DD), mainly by assessing a possible deficit of the mental representation of numerical magnitude. Research in healthy adults has shown that numerosity, duration, and space share a partly common system of magnitude processing and representation. However, in DD,…

Many neurodevelopmental disorders (NDDs) share common learning and behavioural impairments, as well as features such as dysregulation of the oxytocin hormone. Here, we examined DNA methylation (DNAm) in the 1st intron of the oxytocin receptor gene, "OXTR," in patients with autism spectrum (ASD), attention deficit and hyperactivity (ADHD)…

Poletti, Michele – Journal of Learning Disabilities, 2016
The fifth edition of the "Diagnostic and Statistical Manual of Mental Disorders" grouped specific learning disabilities in the single diagnostic category of specific learning disorder (SLD), with specifiers for impairments in reading, written expression, and mathematics. This study aimed at investigating the intellectual profile,…

Quinn, Jamie M.; Wagner, Richard K.; Petscher, Yaacov; Roberts, Greg; Menzel, Andrew J.; Schatschneider, Christopher – Journal of Educational Psychology, 2020
In this large-scale study of students from Title 1 schools (N = 14,773), we used multiple-group latent change score (LCS) modeling to investigate the developmental relations between vocabulary knowledge and reading comprehension in students with a school-identified learning disability (LD; n = 627) and typically developing students (n = 14,146).…

The purpose of this study was to investigate the effects of brain-based learning approach on study habits and test anxiety among first year preparatory school students with learning disabilities. 60 students participated in the present study. Each student participant is of low achievement scores on one or more standardized tests or subtests within…

Wong, Terry T.-Y.; Ho, Connie S.-H.; Tang, Joey – Journal of Learning Disabilities, 2017
Developmental dyscalculia (DD) is a specific learning disability in mathematics that affects around 6% of the population. Currently, the core deficit of DD remains unknown. While the number sense deficit hypothesis suggests that the core deficit of DD lies in the inability to represent nonsymbolic numerosity, the access deficit hypothesis suggests…

Stanford, Emily; Delage, Hélène – First Language, 2020
Working memory (WM) limitations are frequently reported for children with specific learning disorder (SLD). However, WM capacity influences more than literacy and numeracy, as research highlights the contribution of WM to language development, in particular syntax. In this article, the authors study the effect of syntactic intervention, i.e.…

Grünke, Matthias; Boon, Richard T.; Burke, Mack D. – International Journal for Research in Learning Disabilities, 2015
The purpose of this study was to illustrate the use of the randomization test for single-case research designs (SCR; Kratochwill & Levin, 2010). To demonstrate the application of this approach, a systematic replication of Grünke, Wilbert, and Calder Stegemann (2013) was conducted to evaluate the effects of a story map to improve the reading…

Mustafa, Hassan M. H.; Tourkia, Fadhel Ben; Ramadan, Ramadan Mohamed – Journal of Education and e-Learning Research, 2017
The objective of this piece of research is to interpret and investigate systematically an observed brain functional phenomenon which is associated with proceeding of e-learning processes. More specifically, this work addresses an interesting and challenging educational issue concerned with dynamical evaluation of elearning performance considering…

Wang, Enguo; Du, Chenguang; Ma, Yujun – Journal of Learning Disabilities, 2017
This study reports the neurophysiological and behavioral correlates of digital memory retrieval features in Chinese individuals with and without dyscalculia. A total of 18 children with dyscalculia (ages 11.5-13.5) and 18 controls were tested, and their event-related potentials were digitally recorded simultaneously with behavior measurement.…

Fragkouli, Konstantina; Antoniou, Faye; Mouzaki, Angeliki; Ralli, Asimina M.; Kokkali, Vasiliki; Alexoudi, Kariofyllia – Reading & Writing Quarterly, 2022
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…

Goegan, Lauren D.; Harrison, Gina L. – Learning Disabilities: A Contemporary Journal, 2017
The effects of extended time on the writing performance of university students with learning disabilities (LD) was examined. Thirty-eight students (19 LD; 19 non-LD) completed a collection of cognitive, linguistic, and literacy measures, and wrote essays under regular and extended time conditions. Limited evidence was found to support the…

This study was designed to better understand the relations between learning disabilities and different levels of latent cognitive abilities, including general intelligence (g), broad cognitive abilities, and specific abilities based on the Cattell-Horn-Carroll theory of intelligence (CHC theory). Data from the "Differential Ability…

Mammarella, Irene C.; Ghisi, Marta; Bomba, Monica; Bottesi, Gioia; Caviola, Sara; Broggi, Fiorenza; Nacinovich, Renata – Journal of Learning Disabilities, 2016
The main goal of the present study was to shed further light on the psychological characteristics of children with different learning disability profiles aged between 8 and 11 years, attending from third to sixth grade. Specifically, children with nonverbal learning disabilities (NLD), reading disabilities (RD), or a typical development (TD) were…
