COGNITIVE-COMPONENTS TESTS ARE NOT MUCH MORE THAN G - AN EXTENSION OFKYLLONEN ANALYSES

A battery of 10 traditional paper-and-pencil aptitude tests and a batt ery of 25 cognitive-components-based tests were administered to 298 me n and women to investigate the common sources of variance in those bat teries. Earlier confirmatory factor analyses showed each battery to ha ve a hierarchical structure, each with a single higher order factor. T he higher order factor in the paper-and-pencil battery had previously been identified as general cognitive ability, or g. The higher order f actor from the cognitive-components battery had been identified as wor king memory. The intercorrelation of the higher order factors from the two batteries was .994, indicating that both measured g. The proporti on of common variance because of g was greater in the cognitive-compon ents battery than in the paper-and-pencil battery. The correlations be tween each factor based on cognitive components and g averaged .946. D espite theoretical foundations and arguments, cognitive components tes ts appear to measure much the same thing as traditional paper-and-penc il tests.
