Developmental dyscalculia (DD) has long been thought to be determined by multiple components. Dyscalculia has high comorbidity with other learning and developmental disabilities, including reading and writing disorders, attention deficits, and problems in visual/spatial skills, short memory, and working memory. This study aims to assess prevalence…

Students with Special Educational Needs (SEN) in universities are a challenging issue of much concern. University students often need to attend English for Academic Purposes (EAP) classes to complete their studies, as it is necessary for their academic progress. According to Gathercole, Alloway, Willis, and Adams (2006), SEN students show low…

Empirical evidence suggests a phonological loop deficit associated with Down syndrome. A trisomy 21 may be associated with a narrowing of visual attention to fewer than four objects at a time too. In a study with computer tachistoscopy, the hypothesis was confirmed in all 194 persons with trisomy 21. The subitising limit of persons with trisomy 21…

Developmental dyscalculia (DD) is a mathematics learning disorder that affects approximately 5% to 7% of the population. This study aimed to detect the underlying domain-specific and domain-general differences between DD and typically developing (TD) children. We recruited 9-year-old primary school children to form the DD group via a 2-year…

Nonverbal Learning Disability (NLD) has been the focus of four decades of neuropsychological research. However, it has yet to be included as a diagnostic category in the Diagnostic and Statistical Manual of Mental Disorders (i.e., currently in its fifth edition, DSM-5, American Psychiatric Association, 2013). Many of the characteristics associated…

The present study aimed to investigate the effects of the EASY Minds program on working memory and selective attention of a group of Iranian students with maths learning disabilities. The study had a quasi-experimental research design with pre-test, post-test, and follow-up tests. Forty students with maths learning disabilities were randomly…

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…

Working memory is an important component of executive functioning, an area of difficulty for many autistic children. However, executive functioning and working memory are highly malleable throughout childhood, and various student-level and environmental factors play important roles in their development. This study used the Early Childhood…

Little is known about the characteristics of academic overachievers, children whose achievement significantly exceeds IQ. Correlates of overachievement (achievement test scores = 1 SD above IQ), nondiscrepant achievement, and learning disability (LD; achievement = 1 SD below IQ) were analyzed in 1,543 children (739 ADHD, 285 autism, and 519…

This study was designed to investigate the frequency with which students identified as having a Specific Learning Disability (SLD) and a Specific Learning Disability (SLD) combined with Attention Deficit Hyperactivity Disorder (ADHD) are further assessed for deficits of executive function and working memory. Data were collected and analyzed from…

Purpose: Compared to children with typical development, children with dyslexia, developmental language disorder (DLD), or both often demonstrate working memory deficits. It is unclear how pervasive the deficits are or whether the deficits align with diagnostic category. The purpose of this study was to determine whether different working memory…

The current study tested a multiple-cognitive predictor model of word reading, math ability, and attention in a community-based sample of twins ages 8 to 16 years (N = 636). The objective was to identify cognitive predictors unique to each skill domain as well as cognitive predictors shared among skills that could help explain their overlap and…

This study was designed to understand the potential for gained Executive Functioning through an Art Education learning environment by students whom experience a Specific Learning Disability at the High School Level. The author actualizes a limited case study of three students to understand if students whom experience Specific Learning Disabilities…

This dissertation explored the lived experiences of undergraduate and graduate students with learning disabilities and learning-affected disorders within the context of the college writing classroom. Utilizing a critical incident technique (CIT) framework, the dissertation inquired about the writing processes, learning styles, decisions regarding…

Cognitive skill differences that are apparent early in pre-kindergarten (pre-K) might provide predictive insights into risk for learning difficulties at school entry, particularly around early markers of risk for comorbid difficulties in early math and literacy. Domain-specific abilities (approximate number system or ANS acuity, phonological…
