A fairer comparison between the Implicit Association Test and the Single Category Implicit Association Test

The Implicit Association Test (IAT) and the Single Category Implicit Association Test (SC-IAT) are the most common procedures for the assessment of implicit attitudes, stereotypes, and self-concept. The IAT has been found to outperform the SC-IAT in predicting behavioral choices. However, the comparison between the IAT and the SC-IAT might have been affected by many differences in both the administration and the scoring of the two procedures. This study was aimed at developing a common scoring procedure for the IAT and the SC-IAT that would allow a fair comparison of the two. Results supported the higher accuracy of the IAT in predicting the behavioral choice, regardless of the scoring procedure. Implications of the results and limitations of the study are discussed.
