**Goal:** The goal of this project is to better understand how disgust can be changed therapeutically. Disgust seems to be a triggering and maintaining factor in various mental disorders, such as contamination-based obsessive-compulsive disorder. Although exposure with response prevention is a very successful therapeutic method, especially the effects of extinction and habituation of disgust seemed to be reduced compared to fear. In this project we investigate further strategies to improve disgust exposure. Thus, we look at whether emotion regulation strategies such as imagery rescripting and cognitive reappraisal can be used to better change the experience of disgust (Fink, Pflugradt, Stierle & Exner, 2018). In addition, we are looking at whether brain stimulation, such as transcranial direct current stimulation (tDCS), can improve these effects (Fink & Exner, 2019a) and whether brain stimulation can be a helpful therapeutic strategy for obsessive-compulsive disorders in general (Fink & Exner, 2019b). In further studies we want to see if imagery rescripting has a specific effect on disgust or if other imaginative strategies show similar effects (Fink, Platter, Stierle & Exner, submitted).
