Predicting Achievement From WISC-V Composites: Do Cognitive-Achievement Relations Vary Based on General Intelligence?
In order to make appropriate educational recommendations, psychologists must understand how cognitive test scores influence specific academic outcomes for students of different ability levels. We used data from the WISC-V and WIAT-III ( N = 181) to examine which WISC-V Index scores predicted children’s specific and broad academic skills and if cognitive-achievement relations varied by general intelligence. Verbal abilities predicted most academic skills for children of all ability levels, whereas processing speed, working memory, visual processing, and fluid reasoning abilities differentially predicted specific academic skills. Processing speed and working memory demonstrated significant interaction effects with full-scale IQ when predicting youth’s essay writing. Findings suggest generalized intelligence may influence the predictive validity of certain cognitive tests, and replication studies in larger samples are encouraged.
期刊介绍:
The Journal of Psychoeducational Assessment (JPA) publishes contemporary and important information focusing on psychological and educational assessment research and evidence-based practices as well as assessment instrumentation. JPA is well known internationally for the quality of published assessment-related research, theory and practice papers, and book and test reviews. The methodologically sound and impiricially-based studies and critical test and book reviews will be of particular interest to all assessment specialists including practicing psychologists, psychoeducational consultants, educational diagnosticians and special educators.
