当我们对一段经历形成记忆时，我们可以利用我们对世界的图式知识（基于许多先前的情节构建）来预测会发生什么。我们开发了一种新的范式来研究复杂图式的发展如何影响感知过程中的预测过程并影响顺序记忆。参与者在六次训练中学习玩一种新的棋盘游戏（“四人一排”），并反复进行记忆测试，在测试中他们观看并回忆游戏中的动作序列。我们发现，随着图式的发展，参与者逐渐变得更善于记住游戏中的序列，这是由图式一致性动作的准确性提高所驱动的。眼动追踪显示，在编码过程中增加预测性眼球运动，这在专家玩家中最普遍，与更好的记忆有关。我们的结果确定预测是图式知识可以改善情景记忆的一种机制。
When forming a memory of an experience that is unfolding over time, we can use our schematic knowledge about the world (constructed based on many prior episodes) to predict what will transpire. We developed a novel paradigm to study how the development of a complex schema influences predictive processes during perception and impacts sequential memory. Participants learned to play a novel board game (‘four-in-a-row’) across six training sessions and repeatedly performed a memory test in which they watched and recalled sequences of moves from the game. We found that participants gradually became better at remembering sequences from the game as their schema developed, driven by improved accuracy for schema-consistent moves. Eye tracking revealed that increased predictive eye movements during encoding, which were most prevalent in expert players, were associated with better memory. Our results identify prediction as a mechanism by which schematic knowledge can improve episodic memory.
