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,…

There is a virtual consensus regarding the types of language processes, interactions, and material supports that are central for young children to become proficient readers and writers (Shanahan et al., 2008). In this study, we examine these supports in both home and school contexts during children's critical transitional kindergarten year.…

This study explored the effects of ABRACADABRA, a free computer-assisted literacy program, on the reading accuracy and comprehension skills of children diagnosed with autism spectrum disorder (ASD). ABRACADABRA is a balanced literacy instruction program, targeting both code and meaning-based reading abilities. Twenty children with ASD, aged 5-11…

We review the development of the Jamaican home visiting intervention for children under 4 years and its evidence base. The intervention has focused on supporting mothers to promote the development of their children through interacting in a responsive way, labelling the environment and activities. The curriculum is structured and cognitively…

Neurological soft signs (NSSs), minor neurological abnormalities, have been implicated as risk factors for poor cognitive performance in small-scale studies. Here we investigate the associations between NSSs and multiple domains of cognitive performance in a large, population-based cohort and evaluate sex differences in these associations. We…

This study determined the working memory (WM) components (executive, phonological short-term memory [STM], and visual-spatial sketchpad) that best predicted mathematical word problem-solving accuracy in elementary schoolchildren (N = 392). The battery of tests administered to assess mediators between WM and problem-solving included measures of…

The current study examined predictors of academic achievement, measured by standardized test scores, and performance, measured by school grades, in adolescents (Mn = 16.8) who met diagnostic criteria for Attention-Deficit/Hyperactivity Disorder (ADHD)-Combined type in early childhood (Mn age = 8.5; N = 579). Several mediation models were also…

One hundred and fifty-five students (average age of 127 months) were tested using the WRAT-3 reading and arithmetic subtests, the Self-Perception Profile for Children with Learning Disabilities (SPPLD) and the Children's Depression Inventory (CDI). One year later they were again tested with the same instruments. The authors hypothesised that…

Investigated the concurrent validity of the Wechsler Intelligence Scale for Children (Revised) subtests and three IQs compared to Wide Range Achievement Test standard scores, in 28 learning-disabled children. Analysis showed no significant correlations between WISC-R and WRAT scores, indicating a lack of concurrent validity on the WAIS-R. (WAS)

Investigated relationships between the Kaufman Wechsler Intelligence Scale for Children-Revised factors, Wide-Range Achievement Test (WRAT) scores, and visual-motor maturation in children referred because of school-related problems. Results indicated significant correlations between Verbal Comprehension and Reading, Spelling, and Arithmetic…

WISC-R (Wechsler Intelligence Scale in Children-Revised) Verbal and Performance scores were correlated with WRAT-R Wide Range Achievement Test-Revised scores. The verbal score was found to predict reading, spelling, and arithmetic. The performance score did not add significantly to the predictions. Results were consistent with earlier studies.…

Compared regression lines for prediction of Wide Range Achievement Test scores by Wechsler Intelligence Scale for Children and revised WISC Full Scale IQs across race. Results support the use of a common regression line in the prediction of achievement scores for races. (Author)

Although Verbal IQ of the Wechsler Intelligence Scale for Children predicts statistically distinct Wide Range Achievement Test Reading scores dependent on the sex of the child, the differences are of little practical importance. (Author)

Results indicated recall and category clustering were highest following a manipulation to produce semantic encoding of items and lowest when children focused on items' physical features. Reading disabled boys failed to organize or study as effectively as normals. The reading disabled had difficulty in spontaneously generating effective study…

Study investigated efficacy of predicting academic achievement as measured by the WRAT, using Verbal and Performance scores of WISC-R as predictors. Both tests were given to 155 children referred for psychological evaluations. Performance IQ did not significantly predict academic achievement, and Verbal IQ significantly predicted only Reading and…
