ABSTRACT (Ma~xmum 200 words)A paper-and-pencil multiple-aptitude test battery and a computer-based psychomotor test battery were administered to a sample of 354 Air Force recruits. The tests of the multiple-aptitude battery were used to estimate psychometric g and to predict the psychomotor tests. The multiple correlation of the multiple-aptitude tests and each psychomotor test as a criterion was .50, corrected for range restriction.The average correlation of the psychomotor tests and psychometric g, corrected for range restriction and unreliability, was .73. The multiple-aptitude tests and the psychomotor tests were correlated and subjected to a principal components analysis. The average g saturations of the psychomotor and multiple-aptitude tests were .76 and .87, respectively.Confirmatory factor analyses disclosed hierarchical general cognitive and general psychomotor factors, two lower order multiple-aptitude test factors and three lower order psychomotor test factors. iii PREFACE This research and development was accomplished under work unit 77191845 which is dedicated to the study of selection and classification of Air Force Pilots. The authors thank Laurie C. Walters, Melody Darby, and Rick Siem for help in planning the data collection and in statistical analyses. We thank James Earles and Major David Perry for reading drafts and 1Lt Laura Kreitler for producing the figure of the structural model.Comments from Joseph Weeks on the correction for range restriction which helped clarify our thinking were appreciated. Professor Charles Lance, University of Georgia, is thanked for his helpful comments on statistical tests appropriate for the structural models. A special debt of gratitude is owed William C. Tirre for his generosity of time in developing the structural model.
