On the relationship between need for cognition and self-control capacity

In the present study, we examined the hypothesis that individuals’ motivational tendency to engage in effortful information processing (i.e., their need for cognition; NFC) is positively related to their self-control capacity. This hypothesis was based on previous findings that effortful information processing and self-control both depend on a joint strength resource, and that this resource is boosted by frequent use. NFC was assessed via questionnaire. One week later, the participants (N = 46) completed a test of self-control capacity (Stroop Task). As expected, NFC was positively related to self-control capacity but unrelated to general processing speed
