Abstract
This article reviews the Reynolds Intellectual Assessment Scales (RIAS). The RIAS was developed as a theoretically and psychometrically sound instrument designed to measure general intelligence. In contrast to most existing measures of intelligence, the RIAS eliminates dependence on motor coordination, visual-motor speed, and reading skills and can be administered in a short period of time. The RIAS is an individually administered test of intelligence, which has been normed and standardized on an age population from 3 to 94 years. Utilizing the Cattell-Horn Model of Intelligence (Horn & Cattell, 1966), the authors have developed a reliable measure of general intelligence and its two primary components, fluid and crystallized intelligence. The RIAS includes a measure of verbal and non-verbal intelligence and a resultant Composite Intelligence Index (CIX). Verbal intelligence is assessed with tasks involving verbal problem solving and verbal reasoning tasks. Non-verbal intelligence is assessed by visual and spatial ability tasks.
