**Goal**: High disgust sensitivity has a pathogenic influence on several psychological disorders, like for example the obsessive-compulsive disorder subtype contamination and washing (C-OCD) (for review: Cisler, Olatunji, and Lohr, (2009). There are several indications that disgust and fear differ with regard to habituation and extinction. Various studies find that the habituation to disgust stimuli is slower than to fear stimuli (Adams, Willems, & Bridges, 2011; Cougle, Wolitzky-Taylor, Lee, & Telch, 2007; Olatunji, Wolitzky-Taylor, Willems, Lohr, & Armstrong, 2009; Tolin, Woods, & Abramowitz, 2006). Furthermore, disgust, compared to fear, leads to greater resistance in extinction (Mason & Richardson, 2012; Olatunji, Lohr, Sawchuk, & Tolin, 2007). Both effects are responsible that exposure therapy with response prevention in OCD may not reach its full potential. These findings might be associated with a specific disgust related appraisals (Carretié, Ruiz-Padial, López-Martín, & Albert, 2011) as well as a different temporal urgency for processing and reaction that ist signalled by disgust and fear stimuli (Scherer, 2001). To better understand these effects, however, it is important for research to examine the temporal differences in the processing and urgency of disgust and fear. This is what this project is all about.
