Reliability Evidence for the Gibson Assessment of Cognitive Skills (GACS): A Brief Tool for Screening Cognitive Skills Across the Lifespan
Children and adults across the lifespan
What Did Researchers Study?
Researchers examined reliability evidence for the paper-based Gibson Assessment of Cognitive Skills, a brief screening tool measuring working memory, processing speed, visual processing, reasoning, and auditory processing.
What Did Researchers Find?
Internal consistency, split-half reliability, and test-retest reliability results provided evidence supporting the reliability of the screening tool across the ages examined.
This study addresses reliability of the assessment tool; it does not establish that cognitive training produces specific learning outcomes.
