We argue that hope is not an expectancy based on beliefs about pathways to desired goals and personal capacities to act on them, but an experience of the mere possibility of a desired outcome. We propose that in the latter sense, hope has unique motivational consequences for goal striving. Specifically, we predicted that hope buffers against the detrimental impact of negative feedback on goal-progress. The results of the two studies confirmed this prediction. In Study 1, we measured participants’ hopes of attaining a weight-loss goal. In Study 2, we induced hope at solving an unsolvable mathematical puzzle. In both studies, receiving negative feedback on goal-progress resulted in lower levels of success (Study 1) and persistence (Study 2) in goal-striving, but not for participants who experienced hope. We discuss the role of hope as an affective mechanism that functions to regulate energy expenditure in goal-striving.
