人们发现学习自己感兴趣的话题更容易，但人们对内在动机状态影响学习的机制知之甚少。我们使用功能性磁共振成像来研究好奇心（学习的内在动机）如何影响记忆。在即时记忆测试和一天延迟记忆测试中，参与者对他们感兴趣的信息和在高度好奇状态下学到的偶然材料的记忆都有所提高。FMRI结果显示，在高度好奇的状态下，中脑和伏隔核的活动增强。重要的是，中脑和海马体的预期活动以及这些区域之间的功能连接支持了好奇心驱动记忆对偶然材料的益处的个体差异。这些发现表明，支持外在奖励动机和内在好奇心的机制之间存在联系，并强调了激发好奇心对于创造更有效的学习体验的重要性。
People find it easier to learn about topics that interest them, but little is known about the mechanisms by which intrinsic motivational states affect learning. We used functional magnetic resonance imaging to investigate how curiosity (intrinsic motivation to learn) influences memory. In both immediate and one-day delayed memory tests, participants showed improved memory for information that they were curious about, and also for incidental material learned during states of high curiosity. FMRI results revealed that activity in the midbrain and the nucleus accumbens was enhanced during states of high curiosity. Importantly, individual variability in curiosity-driven memory benefits for incidental material was supported by anticipatory activity in the midbrain and hippocampus and by functional connectivity between these regions. These findings suggest a link between the mechanisms supporting extrinsic reward motivation and intrinsic curiosity and highlight the importance of stimulating curiosity in order to create more effective learning experiences.
