THE most used IQ tests do not provide just a single figure as a measure of ability but have at least two (and usually more) scores. For instance, the IQ test most commonly used by psychologists is the WISC (Wechsler Intelligence Scales for Children). This has two main IQ figures, currently called index score: a verbal comprehension index (or verbal IQ) and a perceptual reasoning index (or nonverbal IQ). The verbal index or IQ is a measure of spoken language ability; the score shows how the child performed on tests of vocabulary and verbal reasoning. The nonverbal index or IQ is a measure of visual-spatial ability; here the score shows how the child performed on puzzle- and pattern-based tests. The two IQ scores may be combined to give an overal indication of ability, called general or full scale IQ.
