Armed Services Vocational Aptitude Battery (ASVAB): Predicting Military Criteria from General and Specific Abilities

“…In his landmark summary of aptitude test validation research, Ghiselli (1966) reached conclusions which were opposed to those of McNemar (1964). However, Ghiselli failed to take into account sampling error in the hundreds of validity coefficients used in his meta-analysis.…”

“…!n the following two decades, three major reviews of the literature on the predictive utility of tests of cognitive ability provided evidence of the overarching importance of g for prediction of educational and occupational success criteria (Ghiselli, 1966(Ghiselli, & 1973McNemar, 1964). McNemnar's analysis led him to conclude that differential validity could not be found in a representative multiple-aptitude battery for prediction of educational criteria.…”

A Componential Interpretation of the General Factor in Human Intelligence

“…We shall present here only a cursory examination of the main findings that lead us to accept the existence of a general factor, since careful and thorough reviews of the documentation exist elsewhere (e.g., Eysenck, 197.;Humphreys, 1979;McNemar, 1964). For the most part, we shall assume that a general factor exists, and proceed to what we believe to be the interesting question facing contemporary theorists of intelligence: What is the nature of the general factor?…”

Predicting aircrew training performance with psychometric g

“…For example, McNemar (1964) reported that multiple aptitude batteries achieved little differential validity (Brogden, 1951) compared to tests designed to measure general ability. He reviewed 4,096 validity coefficients of one such test, the Differential Aptitude Test (Bennett, Seashore, & Wesman, 1982), and reported that only four of the eight subtests demonstrated "adequate" differential validity.…”
