The present study explored the effects of state overconfidence on persistent behavior with consideration of feasibility and desirability as mediators. The persistent behaviors of 61 participants (35 women, 26 men; M age = 20.9 yr, SD = 1.9), placed in overconfidence and under-confidence groups based on random positive or negative bogus feedback, were measured. Results showed that participants with overconfidence were more persistent in solving problems than were those with under-confidence. Further mediation analyses revealed that the rating of the feasibility rather than the desirability of the task mediated the influence of state overconfidence on persistent behaviors. These findings provided future support for the self-justification hypothesis, and addressed arguments regarding the origins of overconfidence.
Assuming that the principle of an active-self account holds true in real life, priming certain constructs could selectively activate a working self-concept, which in turn guides behavior. The current study involved two experiments that examined the relationships between stereotypic identity, working self-concept, and memory performance in older adults. Specifically, Study 1 tested whether a stereotype threat can affect older adults' working self-concept and memory performance. A modified Stroop color naming task and a separate recognition task showed that a stereotype threat prime altered the activation of the working self-concept and deteriorated the older adults' memory performance. Additionally, the working self-concept mediated the effect of stereotype threat on memory performance. Accordingly, we designed Study 2 to assess whether priming different identities can alter the working self-concept of the elderly and buffer the stereotype threat effect on memory performance. The results not only were the same as Study 1 but also revealed that activating multiple identities could mitigate the stereotype threat. These results support an active-self account and the efficacy of stereotype threat intervention. This intervention strategy may be able to be used in real situations to help the elderly alleviate stereotype threats and memory impairment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
