The Woodcock-Johnson IV Tests of Cognitive Abilities (WJ IV COG) is a comprehensive assessment battery designed to assess broad and narrow cognitive abilities, as defined by the Cattell-Horn-Carroll (CHC) theory of intelligence. Previous studies examined the invariance of the WJ assessments across sex and age groups using factor analytic methods.…

Although several studies have shown that planning, attention, simultaneous, and successive (PASS) cognitive processes--operationalized with the cognitive assessment system (CAS; Naglieri & Das, 1997)--are significant predictors of academic performance in the general population, little is known about their role among children with superior…

Consideration of the influence of English language skills during testing is an understandable requirement for fair and valid cognitive test interpretation. Several professional standards and expert recommendations exist to guide psychologists as they attempt to engage in best practices when assessing English learners (ELs). Nonetheless, relatively…

Writing is a complex academic task--it involves numerous mental processes. Given the necessity for developing writing skills from elementary to secondary school, this study aimed to investigate the role of broad cognitive abilities derived from the Cattell-Horn-Carroll (CHC) theory of intelligence in predicting skills associated with writing…

The selection and interpretation of individually administered norm-referenced cognitive tests that are administered to culturally and linguistically diverse (CLD) students continue to be an important consideration within the psychoeducational assessment process. Understanding test directions during the assessment of cognitive abilities is…

The authors review the "Shipley-2 Manual," a revised and restandardized version of the Shipley Institute of Living Scale, which is a brief yet robust measure of cognitive functioning and impairment. Like the previous version, the Shipley-2 assesses crystallized ability, which is gained through education and experience, and fluid…

This study examined associations between broad cognitive abilities (Fluid Reasoning [Gf], Short-Term Working Memory [Gwm], Long-Term Storage and Retrieval [Glr], Processing Speed [Gs], Comprehension-Knowledge [Gc], Visual Processing [Gv], and Auditory Processing [Ga]) and reading achievement (Basic Reading Skills, Reading Rate, Reading Fluency,…
