Indirect Assessment of Implicit Disgust Sensitivity

Abstract

We propose a single-block, single-target, Implicit Association Test (SB-ST-IAT) for measuring implicit disgust sensitivity. Based on dual process theories, we tested the construct validity of this new measure using a sample of N = 75 participants. Incremental validity of the newly developed SB-ST-IAT was demonstrated using a disgust sensitivity questionnaire as a direct measure of disgust sensitivity, as well as two behavioral criteria. A controlled approach versus avoidance task with disgusting stimuli (worms) was employed as a measure of controlled behavior. Facial disgust expression and withdrawal of hands and upper body from the disgust stimuli were used as indicators of automatic behavior. Implications of our research for the validation of indirect measures are discussed.
