Prediction of reading by Ga and Gc specific cognitive abilities for low-SES white and hispanic English-speaking children

Predicting Achievement From WISC-V Composites: Do Cognitive-Achievement Relations Vary Based on General Intelligence?

“…As in previous WISC studies (Beaujean et al, 2014;Caemmerer et al, 2018;Glutting et al, 2006;Oh et al, 2004), we found moderate to large relations between children's verbal abilities and their reading and writing performance. Similarly, verbal comprehension knowledge (Gc)-reading relations, including basic reading and reading comprehension, are supported by studies of different editions of the Woodcock-Johnson tests and the single Kaufman Assessment Battery for Children, Second Edition (KABC-II) study (Benson, 2008;Caemmerer, 2018;Cormier et al, 2016;Evans et al, 2002;Floyd et al, 2007;Garcia & Stafford, 2000;Hajovsky et al, 2014;McGrew, 1993;Niileksela et al, 2016;Vanderwood et al, 2002;Zaboski et al, 2018). CHC theory can be applied to the interpretation of many different cognitive tests including the WISC, WJ, and KABC.…”

“…Children's verbal comprehension knowledge abilities show a strong, consistent relation to their basic reading and reading comprehension skills. This strong relationship was found across several tests, including the WISC-V, Kaufman Assessment Battery for Children, Second Edition (KABC-II), and multiple editions of the Woodcock-Johnson tests (WJ; Benson, 2008;Caemmerer, 2018;Cormier et al, 2016;Evans et al, 2002;Floyd et al, 2007;Garcia & Stafford, 2000;Hajovsky et al, 2014;McGrew, 1993;Niileksela et al, 2016;Vanderwood et al, 2002;Zaboski et al, 2018).…”

Intelligence and Its Relationship to Achievement

“…Specifically, McGrew et al (1997) and Keith (1997) reported significant correlations between auditory processing (Ga) and crystalized intelligence (Gc) and reading achievement in school-age children from the WJ-R standardization sample. Similarly, Garcia and Stafford (2000) conducted a regression analysis and revealed that reading achievement could be significantly predicted by Ga and Gc for first and second grade students from lower-income families.…”

Los Angeles County Young Children’s Literacy Experiences, Emotional Well-Being and Skills Acquisition: Results from the Los Angeles Family and Neighborhood Survey

“…To assess parental literacy levels, L.A.FANS administered the passage comprehension test from the WJ-R The WJ-R has been shown to be a reliable test of reading and problem solving ability among individuals aged 3 to 99 years old (Tusing, 1999;Garcia & Stafford, 2000). To date, no systematic comparison has been made with Stanford-9 (SAT-9) used in the Los Angeles Unified School District and other L.A. County districts.…”
