Literature suggest thet checking behaviors are aimed at reducing feelings of uncertainty both in clinical samples with obsessive-compulsive disorder and in general population. Previous studies also showed that deontological guilt is an emotion often associated with obsessive-compulsive disorder. Thus, the aim of the current study was to investigate the differences in checking behaviors in the condition of high versus low uncertainty, by exploring the moderating role of deontological versus altruistic guilt. Partecipants were 108 undergraduate Italian university students who took part in a visual search a difference was more consistent when participants experienced deontological rather then altruistic guilt. Limitations and further directions are discissed.
