人们对先前获得的知识如何与新学到的知识相互作用以及先前知识如何促进语义和“图式”学习产生了极大的兴趣。在情景记忆的研究中，它与干扰广泛相关。很少有研究探讨了干扰和促进之间的平衡，在整个过程中的时间延长的事件和它的个体差异。在本研究中，我们招募了120名参与者进行为期两天的空间导航实验，其中第2天的参与者导航从第1天开始学习的虚拟路线，同时还学习新路线。关键的是，一半的新迷宫与旧迷宫重叠，而另一半没有，使我们能够在空间情景学习的背景下研究干扰和促进。总的来说，我们发现，与先前学习的路线重叠的新迷宫中的导航性能明显比新的非重叠迷宫差，这表明了主动干扰。有趣的是，我们发现在熟悉的环境中，在与以前学习的路线没有直接重叠的地方，新路线的记忆促进作用。认知地图准确性与前摄干扰呈正相关。此外，具有高自我报告空间能力和/或偏好基于位置的学习的参与者经历了更多的主动干预。综上所述，我们的研究结果表明：1）记忆干扰和促进可以同时发生作为先前学习的函数，2）在一条路线内的前摄干扰作为与旧知识重叠程度的函数而变化，3）空间能力和策略的个体差异可以调节前摄干扰。
There has been great interest in how previously acquired knowledge interacts with newly learned knowledge and how prior knowledge facilitates semantic and “schema” learning. In studies of episodic memory, it is broadly associated with interference. Very few studies have examined the balance between interference and facilitation over the course of temporally-extended events and its individual differences. In the present study, we recruited 120 participants for a two-day spatial navigation experiment, wherein participants on Day 2 navigated virtual routes that were learned from Day 1 while also learning new routes. Critically, half of the new mazes overlapped with the old mazes, while the other half did not, enabling us to examine interference and facilitation in the context of spatial episodic learning. Overall, we found that navigation performance in new mazes that overlapped with previously-learned routes was significantly worse than the new non-overlapping mazes, suggesting proactive interference. Interestingly, we found memory facilitation for new routes in familiar environments in locations where there was no direct overlap with the previously-learned routes. Cognitive map accuracy positively correlated with proactive interference. Moreover, participants with high self-report spatial ability and/or a preference for place-based learning experienced more proactive interference. Taken together, our results show that 1) both memory interference and facilitation can co-occur as a function of prior learning, 2) proactive interference within a route varied as a function of the degree of overlap with old knowledge, and 3) individual differences in spatial ability and strategy can modulate proactive interference.
