Both external motivational incentives (e.g., monetary reward) and internal motivational incentives (e.g., self-determined choice) have been found to promote memory, but much less is known about how these two types of incentives interact with each other to affect memory. The current study (N = 108) examined how performance-dependent monetary rewards affected the role of self-determined choice in memory performance, also known as the choice effect. Using a modified and better controlled version of the choice paradigm and manipulating levels of reward, we demonstrated an interactive effect between monetary reward and self-determined choice on 1-day delayed memory performance. Specifically, the choice effect on memory decreased when we introduced the performance-dependent external rewards. These results are discussed in terms of understanding how external and internal motivators interact to impact learning and memory.
外部激励因素（例如，金钱奖励）和内部激励因素（例如，自主选择）都被发现可以促进记忆，但人们对这两种激励因素如何相互作用以影响记忆知之甚少。本研究（N=108）考察了绩效相关的金钱奖励如何影响自主选择在记忆表现中的作用，即选择效应。使用修改后的、控制更好的选择范式版本，并操纵奖励水平，我们证明了金钱奖励和自主选择对 1 天延迟记忆表现的交互作用。具体来说，当引入基于绩效的外部奖励时，记忆的选择效应会降低。这些结果是根据理解外部和内部激励因素如何相互作用以影响学习和记忆来讨论的。
