Reward improves memory through both encoding and consolidation processes. In this preregistered study, we tested whether reward effects on memory generalize from high-rewarded items to low-rewarded but episodically related items. Fifty-nine human volunteers incidentally encoded associations between unique objects and repeated scenes. Some scenes typically yielded high reward, whereas others typically yielded low reward. Memory was tested immediately after encoding ( = 29) or the next day ( = 30). Overall, reward had only a limited influence on memory. It did not enhance consolidation and its effect did not generalize to episodically related stimuli. We thus contribute to understanding the boundary conditions of reward effects on memory.
奖励通过编码和巩固过程来改善记忆。在这项预先注册的研究中，我们测试了奖励对记忆的影响是否从高奖励的项目推广到低奖励但与情节相关的项目。59 名人类志愿者偶然地在独特的物体和重复的场景之间编码关联。一些场景通常会产生高奖励，而另一些场景通常会产生低奖励。记忆在编码后立即进行测试（n=29）或第二天进行测试（n=30）。总的来说，奖励对记忆的影响是有限的。它不能增强巩固，其效果也不能推广到情节相关的刺激。因此，我们有助于理解奖励对记忆的影响的边界条件。
