Relative roles of cognitive ability and practical intelligence in the prediction of success.
Initial investigations into the construct of practical intelligence have identified a new general factor of practical intelligence (gp), which is believed to be independent of general cognitive ability. This construct, gp, is also believed to be a better predictor of success than cognitive ability, personality, or any combination of variables independent of gp. The existence of this construct and its independence from Spearman's g is, however, under debate. The purpose of the present study is to investigate both the relationship between gp and g and the relative roles of practical intelligence and cognitive ability in the prediction of success. The participants included 197 college students. Each completed both the Multidimensional Aptitude Battery and Sternberg and Wagner's measure of practical intelligence in academic psychology. The results of structural equation modeling support Sternberg and Wagner's assertion that practical intelligence and general cognitive ability are relatively independent constructs. Results of regression analysis, however, do not support their contention that practical intelligence is related to success after controlling for general cognitive ability. Implications of these results for research and theory on practical intelligence are discussed.
