This study investigated the relationship between mathematics difficulties and psychopathology in a large community sample (N = 881) of youth (8-18 years of age) in the United States. The primary aims of the study were to (a) test the associations between mathematics difficulties and specific components of internalizing, externalizing, attention,…

This study investigated the association of a performance-based measure of executive functioning (EF) with academic, social, and behavioral performance ratings in a convenience sample of 153 children aged 5 to 12 (78% male, 83% Caucasian) diagnosed with attention-deficit/hyperactivity disorder (ADHD). Multivariate regression showed that above 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:…

This study examined the role of adolescents' perceived close relationships with significant others (attachment relationships with mothers/fathers, appraisal of homeroom teacher as secure base, and quality of peer friendship) in explaining differences in their socioemotional and behavioral functioning (peer-network/peer-dyadic loneliness,…

Children with academic and behavioral difficulties have been found to report overly positive self-perceptions of performance in their areas of specific deficit. Researchers typically investigate self-perceptions in reference to both actual performance and ratings by teachers, peers, and parents. However, few studies have investigated whether or…

Although behavioral difficulties are well documented in reading disabilities, little is known about the relationship between math ability and internalizing and externalizing behaviors. Here, we use standardized measures to investigate the relation among early math ability, math anxiety, and internalizing and externalizing behaviors in a group of…

We analyzed two nationally representative, longitudinal data sets of U.S. children to identify risk factors for persistent mathematics difficulties (PMD). Results indicated that children from low socioeconomic households are at elevated risk of PMD at 48 and 60 months of age, as are children with cognitive delays, identified developmental delays…

The co-occurrence of reading disorder (RD) and attention-deficit/hyperactivity disorder (ADHD) has received increasing attention. This review summarizes the epidemiology, treatment strategies, psychosocial impact, and economic burden associated with the co-occurrence of these conditions. Common genetic and neuropsychological deficits may partially…

Errors in written multi-digit computation were investigated in children with math difficulties. Third- and fourth-grade children (n = 291) with coexisting math and reading difficulties, math difficulties, reading difficulties, or no learning difficulties were compared. A second analysis compared those with severe math learning difficulties, low…

The authors examined behavior problems in a matched sample of 58 youths with persistent dyscalculia (PD) and nonpersistent dyscalculia (NPD). Participants were classified as having dyscalculia at age 10-11 years. Parents completed the Child Behavior Checklist for their children at ages 10-11, 13-14, and 16-17 years, while the youths did so at the…

This study employed a correlated trait-correlated method application of confirmatory factor analysis to disentangle trait and method variance from measures of attention-deficit/hyperactivity disorder obtained at the college level. The two trait factors were "Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition" ("DSM-IV")…

Research and research needs on the peer relationships of hyperactive children are reviewed. Among topics studied are negative perceptions by peers and disruptive classroom behavior. Topics which need to be addressed include effects of age, sex, and cognitive deficits on relations. (CL)

Forty-three adolescents with learning disabilities attending a residential school were assessed for externalizing behavior problems and academic achievement in reading, spelling, and arithmetic. Some indices of externalizing behavior predicted some measures of underachievement, but the reverse relation was not evident. Inattention interfered with…

Characteristics of a behavioral approach to remediating academic deficits of learning disabled (LD) children are reviewed. The behavioral approach encompasses individualization and mastery learning, direct teaching, and an emphasis on measurement. (SEW)

The literature review finds valid the distinction within the diagnostic category of Attention Deficit Disorder (ADD) of either the presence or absence of hyperactivity. ADD children without hyperactivity exhibit less serious conduct problems, are less impulsive, less rejected by peers, but more socially withdrawn, and more likely to exhibit…
