We explored the challenges, limitations, and potential effectiveness of a large-scale computerized working memory and numeracy intervention in the classroom with children at risk of mathematical learning disabilities (n = 428, M[subscript age] = 83.85 months, 41% female). Children were assigned to four different treatment protocols (working memory…

This study investigated the stability of latent classes of students with learning disabilities among a heterogeneous sample of elementary-aged children whose first language is Spanish. To this end, children (N = 284) in Grades 1, 2, and 3 at Wave 1 (Year 1) were administered a battery of vocabulary, reading, math, and cognitive measures…

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…

This study investigated whether a latent class of children with math difficulties (MD) or math learning disabilities (MLD) emerged within a heterogeneous sample of learners. A latent class analysis was computed on children (N = 447) in Grade 3 who were administered a battery of math, reading, and cognitive measures. The analysis yielded four…

Explanations of the marked individual differences in elementary school mathematical achievement and mathematical learning disability (MLD or dyscalculia) have involved domain-general factors (working memory, reasoning, processing speed, and oral language) and numerical factors that include single-digit processing efficiency and multidigit skills…

This study investigated the prevalence and stability of latent classes at risk for reading disabilities (RD) in elementary-aged children whose first language is Spanish. To this end, children (N = 489) in Grades 1, 2, and 3 at Wave 1 were administered a battery of reading, vocabulary, and cognitive measures (short-term memory [STM], working memory…

Reasons for poor performance on the Digit Span subtest of the Wechsler Intelligence Scale for Children-Revised were examined, using learning disabled (LD) children who performed poorly on the test, LD children who performed normally, and average children. One LD group was unable to establish mnemonic codes for familiar auditory stimuli.…

Two studies investigated (1) the ability of learning disabled children to perform tasks that specifically demand the recognition and production of main-idea statements, and (2) their ability to detect an inappropriate sentence in a paragraph. (PN)

In two experiments, the authors tested the effect of two types of reading on the spelling memory of strange or sound-spelling inconsistent words in Dutch students with and without learning disabilities: standard reading and regularized reading. Standard reading refers to reading the word the way it has to be read. Regularized reading refers to…

In two experiments, the importance of mnemonic illustrations for improving the learning and memory performance of learning disabled adolescents was studied. Results showed that students learned more when they studied passages with mnemonic pictures and that mnemonic instruction facilitated students ability to make inferences about information…

Three experiments exploring the relationship of cognitive effort to the differences in word recall between skilled and learning disabled readers are described. Results suggest the amount of cognitive effort that can be effectively expended to produce a distinctive memory trace is related to individual differences in attentional capacity.…

An experiment was designed to compare the speed with which normal and disabled readers in two age groups retrieved semantic information from memory. Results indicate that disabled readers need more time to retrieve categorical information from memory than normal readers. (Author/LMO)

Three studies of language comprehension skills compared 9- and 10-year-old learning-disabled children (LDC) with difficulty retaining verbal information (n=8) with LDC with normal memory spans (n=8) and normally achieving children (n=16). LDC did not have significant impairments in listening comprehension. However, LDC may experience difficulties…

Effects of task demands, age, and skill level on memory and metamemory performance were examined for 62 average and 66 low-achieving learning-disabled children. Memory improved with age and skill level, and strategic metamemory revealed age and skill-level differences, but taxonomic metamemory revealed age differences in the average group only.…
