Disgust, Need for Affect, and Responses to Microbiome Research

Contributing to the literature on affective processing and attitude formation, this study investigates the effects of a discrete emotion (disgust) and an emotional disposition (need for affect [NFA]) on support for regulation in the context of microbiome research. Data from a web-based experiment (N = 1,005) showed that experienced disgust mediated the effect of disgust-eliciting information on support for regulation. This mediated relationship was moderated by NFA. More specifically, NFA moderated the path between experienced disgust and regulatory attitudes but not that between message exposure and experienced disgust. The two dimensions of NFA played different moderating roles: Emotional approach amplified the relationship between disgust and the attitudinal outcome, whereas emotional avoidance attenuated it. The study furthers understanding about how NFA influences emotional processing and contributes to research on disgust as a relatively understudied discrete emotion.
