The diagnostic utility of the Woodcock-Johnson III Tests of Cognitive Abilities and Clinical Clusters was assessed in a sample of 52 children (26 Attention Deficit/Hyperactivity Disordered (ADHD) and 26 matched controls). Multivariate analysis of variance followed by post-hoc testing and d-ratios yielded some statistically significant and…

The Cattell-Horn-Carroll (CHC) factors of the Woodcock-Johnson Arabic Tests were studied with a group of children with dyslexia (n = 37), children with Intellectual Disability (ID) (n = 37), and average children (n = 37). A total sample of 111 Jordanian children with mean age of 116 months participated in the study. The purpose of this study was…

The purpose of this article is to provide the reader with insight into the clinical reasoning process involved in the assessment and intervention planning for a child with a reading disability. A Cattell-Horn-Carroll (CHC) theoretical/neuropsychological approach shall serve as the foundational theoretical framework for this case study, and…

The Cattell-Horn-Carroll (CHC) factors of the Woodcock-Johnson (WJ) Arabic Tests of Cognitive Abilities were studied with a group of students at risk of Math Disability (MD) (n50) and average students (n50) between second and fourth grades. Specifically, several statistical analyses were conducted using the seven CHC factors identified by the WJ…

Many children with problems learning in school can have educational deficits due to underlying auditory processing disorders (APD). For these children, they can be identified as having auditory learning disabilities. Furthermore, auditory learning disabilities is identified as a specific learning disability (SLD) in the IDEA. Educators and…

The purpose of this research was to investigate the cognitive abilities that explain reading comprehension across childhood and early adulthood. Drawing from the standardization sample of the Woodcock-Johnson III, analyses were conducted with large samples at age levels spanning early childhood to early adulthood: 5 to 6 (n = 639), 7 to 8 (n =…

The Woodcock-Johnson-Fourth edition (WJ IV; Schrank, McGrew, & Mather, 2014a) and the Wechsler Intelligence Scale for Children-Fifth edition (WISC-V; Wechsler, 2014) are two of the major tests of cognitive abilities used in school psychology. The complete WJ IV battery includes the Woodcock-Johnson IV Tests of Cognitive Abilities (Schrank,…

Psychoeducational assessment, and specifically cognitive testing, is important to the role of school psychologists; however, the utility of such testing has been called into question, and its future is unclear. Researchers are divided into two camps. One side grew disenchanted with cognitive testing after the failure of the discrepancy method to…

Elementary school children in three grade groups (Grades K/1, 3, and 5/6) completed either the auditory or the visual 1/9 vigilance task from the Gordon Diagnostic System (GDS) as well as subtests from the Wechsler Intelligence Scale for Children--Third Edition and auditory or visual processing subtests from the Woodcock-Johnson Tests of Cognitive…
