摘要:

努力(Effort)与奖赏系统关系密切。当前关于努力在奖赏加工中的作用存在两个截然相反的观点:努力是一种成本还是一种奖赏?理论模型包括:其一, 努力是一种成本, 会降低奖赏的价值, 相应的理论解释包括内部成本模型、机会成本模型及信号模型等; 其二, 努力能够提升奖赏的价值, 相应的理论解释包括认知失调和努力的合理化模型、习得性勤奋理论及认知需求理论等。这两种观点均得到了来自于动物学、行为学、电生理学以及神经影像学等证据的支持。未来研究需要对努力准确定义, 从时间进程角度对努力的理论进行整合, 进一步考察努力的相关影响因素。

关键词: 努力, 成本, 奖赏

Abstract:

Effort plays a critical role in reward processing, which has been couched within two contradictory theories regarding effort as either a cost or a reward. On the one hand, effort is regarded as a cost whereby it reduces reward value, which has been articulated in the intrinsic cost model, the opportunity cost model, and the signal model. On the other hand, effort can boost the value of reward, which has been explained by the cognitive dissonance model, the learned industriousness model, and the need for cognition model. Both theories have been supported by converging evidence from animal studies, human behavioral studies, electrophysiological studies, and neuroimaging studies. Future research is needed to specify the definition of effort, integrate the competing theories in terms of the time course of effort expenditure, and explore potential factors that impact on effort.

Key words: effort, cost, reward
