Incidental emotions associated with uncertainty appraisals impair decisions in the Iowa Gambling Task

International audienceWith the Appraisal Tendency Framework, it has been established that (un)certainty appraisals associated with incidental emotions trigger the kind of information processing to cope with situation. We tested the impact of (un)certainty-associated emotions on a sequential task, the Iowa Gambling Task. In this task, intuitive processing is necessary to lead participants to rely on emotional cues arising from previous decisions and to making advantageous decisions. We predicted that certainty-associated emotions would engage participants in intuitive processing, whereas uncertainty-associated emotions would engage them in deliberative processing and lead them to make disadvantageous decisions. As expected, we observed in two distinct experiments, that participants induced to feel uncertainty (fear, sadness) were found to decide less advantageously than participants induced to feel certainty (anger, happiness, disgust)
