Convergent, Discriminant, and Incremental Validity of the Pictorial Attitude Implicit Association Test and the Picture Story Exercise as Measures of the Implicit Power Motive

The Pictorial Attitude Implicit Association Test (PA–IAT) has recently been proposed as new measure of implicit motives. We report a study that provides the first evidence for the convergent validity of the PA–IAT by showing that the PA–IAT correlates significantly with a standard measure of implicit motives [i.e. the Picture Story Exercise (PSE)]. Discriminant validity of the PA–IAT was verified in the sense that the PA–IAT shared virtually no common variance with explicit motive measures. Our analyses revealed that the PA–IAT and PSE can best be conceived as related but distinct measures. We further showed that the PA–IAT had incremental validity in predicting performance on a memory recall task over and above the PSE. In general, our results confirm that the PA–IAT is a valid measure of implicit motives and can serve as valid alternative to the PSE. Copyright © 2012 John Wiley & Sons, Ltd.
