title: An ontological test of the IAT: Self-activation can increase predictive validity.
abstract: Extensive research has been conducted demonstrating the predictive validity and reliability of the Implicit Association Test (IAT) for a broad array of behaviors and contexts. However, less work has been done examining its underlying construct validity. This contribution focuses on examining whether a core theoretical foundation of the IAT paradigm is valid, specifically, whether the IAT effect draws on the social knowledge structure (SKS). We present four studies within different domains that show that the IAT does indeed appear to draw on the SKS. The data show that activation of the self before the categorization task enhances the predictive validity of the IAT, as one would expect if the IAT reflects the SKS. We discuss theoretical reasons for these findings, with emphasis also on underlying statistical/psychometric issues.
