General Cognitive Ability Predicts Job Performance.

摘要

The roles of general ability (g) and specific abilities (s) were investigated as predictors of several job performance criteria for Air Force enlistees in 8 jobs. General cognitive ability and specific abilities (the interaction of general ability and experience) were defined by scores on the first and subsequent principal components of the enlistment selection and classification test, the Armed Services Vocational Aptitude Battery. Multiple regression conducted in correlation matrices corrected for range restriction revealed that g was the best predictor of all criterion measures and that s added a statistically significant but practically small amount to predictive efficiency. For classification of large numbers of applications into large numbers of jobs the incremental prediction due to s could be useful.
