Perseverance toward goals that carry short-term costs is an important component of adaptive functioning. The present experiments examine the role that the emotion pride may play in mediating such perseverance. Across 2 studies, pride led to greater perseverance on an effortful and hedonically negative task believed to be related to the initial source of pride. In addition, the causal efficacy of pride was further demonstrated through dissociating its effects from related alternative mechanisms. Study 1 differentiated the effects of pride from self-efficacy. Study 2 differentiated the effects of pride from general positive affect. Taken together, these findings provide support for the proposed motivational function of pride in which this emotion serves as an incentive to persevere on a task despite initial costs.
