The present study examined whether temporal processing (TP) is associated with reading of a non-alphabetic script, that is, Chinese. A total of 126 primary school-aged Chinese children from Taiwan (63 children with dyslexia) completed cross-modal, visual, and auditory temporal order judgment tasks and measures of Chinese reading and…

The aim of the present study was to investigate the associations between elementary school children's mathematical achievement and their conservation abilities, visuospatial skills, and numerosity processing speed. We also assessed differences in these abilities between children with different types of learning problems. In Study 1 (N = 229), we…

This article reviews the results of a meta-analysis of the experimental published literature that compares the academic, cognitive, and behavioral performance of adults with reading disabilities (RD) with average achieving adult readers. The meta-analysis shows that deficits independent of the classification measures emerged for adults with RD on…

As a group, participants with attention-deficit/hyperactivity disorder (ADHD) are impaired in academic performance and learning. This may be due to a mild intellectual impairment, impaired attention, or inability to allocate sufficient effort. If the latter is the case, this should be evident in the learning strategies applied. Four indices of…

The aim of the study was to examine how goal-setting skills of children with attention-deficit/hyperactivity disorder (ADHD) can be predicted with elements of working memory. The study involved 30 children with an ADHD diagnosis and 30 healthy volunteers. The IQ of the participants was assessed, and ADHD symptoms were evaluated by parents. Each of…

The project Adult Dyslexia and Attention Deficit Disorder in Finland (Project DyAdd) compares adults (n = 119, 18-55 years) with dyslexia, attention-deficit/hyperactivity disorder (ADHD), dyslexia together with ADHD (comorbid), and healthy controls with neuropsychological, psychophysical, and biological methods. The focus of this article is on the…

Results of the comparison of metacomponential functioning and knowledge acquisition of adults with either mild mental retardation or learning disabilities found that (1) knowledge base is the best predictor of metacomponential skill, (2) metacomponential orchestration differentiates the two groups, and (3) IQ mediates metacognition, but does not…

This study, with 17 young adults with attention deficit hyperactivity disorder (ADHD) and 62 without ADHD, found no significant correlations between full scale IQ and scores on the Test of Variables of Attention (TOVA). However, analysis of variance revealed that subjects with ADHD made more errors of omission on the TOVA than did controls.…

Children (N=20, age 9-12) with severe dyslexia were slower in counting from memory and naming alternating digits and letters than children with milder reading impairment. The children most disabled also had poorer phonological sensitivity, shorter digit spans, and lower verbal intelligence quotients. (Author/DB)

A sample of 133 Spanish children (ages 8 to 13) was classified by IQ and reading level and given a lexical processing task. The study found that IQ did not explain differences between learning-disabled (LD) or nondisabled (NLD) children in lexical processing. Lexical and sublexical parameters had a greater influence on LD students than NLD…
