The inspection time and over-claiming tasks as predictors of MBA student performance

Elementary cognitive tasks (ECTs) are typically used in laboratory settings for basic research on the structure of intelligence. More recently, ECTs have been shown to predict important educational and clinical outcomes. Here we found that ECTs possess both criterion and incremental validity over IQ and the graduate management admission test (GMAT) as predictors of (N = 116) MBA student grades and scores on a capstone exam. Validity coefficients for the ECTs ranged from 0.24 to 0.50. A median split on an ECT component showed that the best-performing ECT group had substantially higher grades, exam scores, IQs and GMAT scores. The inspection time ECT possessed significant incremental validity over both IQ and the GMAT. ECTs could therefore be promising additions to the arsenal of assessment techniques currently used in predicting important real-world outcomes.
