Although the pre-existing studies have shown that power can significantly affect individual time cogni-tion,the mechanism underlying this relationship is not clear.The purpose of this review is to reveal the potential mechanisms underlying the effect of power on time cognition by systematically summarizing the existing empirical and theoretical studies.Specifical-ly,research has shown that high-power people(vs.the low)are more likely to underestimate the expected time needed to complete tasks and overestimate the available time resource at present.Moreover,indi-viduals possessing high power also perceive the tem-poral distance between present and future much closer and show a lower level of temporal discounting.In summary,the mechanisms underlying the effect of power on time cognition involve attention,motivation,sense of control,temporal self,and thinking style.Future studies are necessary to further examine the effect of power on time cognition from the perspective of more ecological interpersonal relationship and so-cial situation,investigate the regulatory role of situa-tional cues and individual's goal-orientation in the association of power with prosocial behaviors,and expand the effect of power from the cultural back-ground.
