Document Summary

Iq) than for high (. 23 and . 26, respectively) (detterman & daniel, 1989). Once g is derived, it correlates very highly with g derived from any other sample of tests of abstract reasoning (r > . 9). Furthermore, g itself is generally a better predictor of future performance on tasks which require abstract reasoning than is any single test of abstract reasoning. How intelligence should be partitioned at higher resolution levels than g is subject to debate. It is arguably reasonable, however, to consider g"s differentiation in terms of nonverbal and verbal ability, which correspond, roughly, to what has been considered fluid and crystallized intelligence. Verbal ability can be tapped quickly and easily using measures of vocabulary, which are potent indicators of acquired knowledge (probably because vocabulary tests assess literacy efficiently and accurately). Nonverbal ability, which is strikingly similar to g, can be most efficiently and accurately measured with progressive matrices tests, which require the decomposition of a sequential complex.
