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…

Obesity, physical activity, and sedentary behavior in childhood are important indicators of present and future health and are associated with school-related outcomes such as academic achievement, behavior, peer relationships, and self-esteem. Using logistic regression models that controlled for gender, age, ethnicity/race, and socioeconomic…

The present study evaluated the stability of math learning difficulties over a 2-year period and investigated several factors that might influence this stability (categorical vs. continuous change, liberal vs. conservative cut point, broad vs. specific math assessment); the prediction of math performance over time and by performance level was also…

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…

Three groups of children of different ages who were considered by their teachers as showing symptoms of attention-deficit/hyperactivity disorder (ADHD) and matched controls were tested in a series of expressive writing tasks, derived from a standardized writing test. In the first study, 24 sixth- and seventh-grade children with ADHD symptoms wrote…

The study examined the developmental lag hypothesis for learning disabilities by evaluating dichotic listening ability using both free recall and directed attention conditions in 24 learning disabled (LD) adults. Findings indicated LD adults showed similar deficits in lateralized selective auditory linguistic processing as children with LD. (DB)

The study examined the demographic distribution of 102 subjects with attention deficits in the Wechsler Intelligence Scale for Children-Revised standardization sample. Although neither age nor occupational status were significant, males and female residents of the West were overrepresented. (Author/DB)

Data from three studies identified the cognitive deficits associated with reading difficulties as distinct from attentional deficits. The studies found consistent cognitive deficits (especially naming and phonological awareness) associated with difficulty in reading. Deficits were consistent across samples, developmental levels, definitions, and…

This article presents results from two interrelated studies. The first study conducted a meta-analysis of the published literature since 1990 to determine the magnitude of achievement problems associated with attention-deficit/hyperactivity disorder (ADHD). Effect sizes were significantly different between participants with and without ADHD…

This study investigated early clinical differences between 27 children (ages 0-4) with pervasive developmental disorder not otherwise specified and 27 children with attention deficit disorder. Results revealed almost no differences between both groups with respect to pregnancy or birth complications and suggest that differences become more…

This study examined early childhood characteristics of 82 11-year- old boys with either reading disabilities (RD) only, attention-deficit/hyperactivity disorder (ADHD) only, or both conditions. At ages 3 and 5 the RD only boys had performed poorly on measures of receptive and expressive language, whereas the RD/ADHD groups performed poorly on…
