The purpose of this analysis was to describe cognitive processes associated with comorbid difficulty between word reading (WR) and mathematics computation (MC) at the start of first grade among children selected for WR and MC delays. A sample of 234 U.S. children (mean age 6.50 years, SD = 0.31) was assessed on WR, MC, core cognitive processes…

Rules and regularities of language are typically processed in an implicit and effortless way in the human brain. Individuals with developmental dyslexia have problems in implicit learning of regularities in sequential stimuli, but the neural basis of this deficit has not been studied. This study investigated extraction and utilization of a complex…

The note- and test-taking skills of typically functioning undergraduates are significantly and positively related to handwriting speed, listening comprehension, background knowledge and sustained attention. This study attempted to replicate these findings with two groups of high school students--those with and without the diagnosis of a learning…

Effectiveness of individual and group-based neuropsychological interventions on cognitive aspects of dyslexia in young adults was evaluated. Dyslexic adults were randomly assigned into individual intervention (n = 40), group intervention (n = 40), or wait-list control group (n = 40). The interventions focused on cognitive strategy learning,…

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…

High comorbidity rates between reading disorder (RD) and mathematics disorder (MD) indicate that, although the cognitive core deficits underlying these disorders are distinct, additional domain-general risk factors might be shared between the disorders. Three domain-general cognitive abilities were investigated in children with RD and MD:…

Sequential regression was used to evaluate whether language-related working memory components uniquely predict reading and writing achievement beyond cognitive-linguistic translation for students in Grades 4 through 9 (N = 103) with specific learning disabilities (SLDs) in subword handwriting (dysgraphia, n = 25), word reading and spelling…

The purpose of the present study was twofold: (a) to examine the extent to which Chinese dyslexic children experience deficits in phonological and orthographic processing skills and (b) to examine if Chinese dyslexia is associated with deficits in Planning, Attention, Simultaneous, and Successive (PASS) processing. A total of 27 Grade 4 children…

This investigation analyzed the relation between cognitive functioning and mathematical achievement in 114 students in fourth, fifth, and sixth grades. Differences in cognitive performance were studied concurrently in three selected achievement groups: mathematical learning disability group (MLD), low achieving group (LA), and typically achieving…

The primary purpose of the present study is to evaluate the emotional experience of students with (n = 52) and without attention problems (n = 272) during an achievement task. A secondary purpose of the present study is to compare students' emotional response to various stimuli, when motivated by various achievement goals. Participants were…

Methylphenidate (MPH) often ameliorates attention-deficit/hyperactivity disorder (ADHD) behavioral dysfunction according to "indirect" informant reports and rating scales. The standard of care behavioral MPH titration approach seldom includes "direct" neuropsychological or academic assessment data to determine treatment…

The authors examined the relationships between reading comprehension, visual attention, and magnocellular processing in 42 Grade 7 students. The goal was to quantify the sensitivity of visual attention and magnocellular visual processing as concomitants of poor reading comprehension in the absence of either vision therapy or cognitive…

This paper selectively reviews research on event-related potentials (ERPs) during cognitive processing among children with attention deficit disorder. Research indicates that performance deficits during sustained attention are coupled with reduced amplitude of the P3B component of the ERP, which may be increased with stimulants. P3B latency and…

Poor performance on the search task, which differentiated the clinical groups from the normal group but not from one another, was associated across groups with adverse conduct ratings, lower achievement, and lower scores on the Wechsler Intelligence Scale for Children (WISC) Arithmetic, Coding, Information, Digit Span (ACID) subtests.

A major focus in reading difficulty is lack of automaticity in decoding, which overloads the attentional system, leads to the use of small, meaningless visual processing units such as the individual letter, places heavy demands on short-term memory, and interferes with comprehension. Techniques for diagnosis and remediation are noted. (Author/JW)
