In the present study, the authors offer a window onto the mechanisms that drive the Hebb repetition effect through the analysis of eye movement and recall performance. In a spatial serial recall task in which sequences of dots are to be remembered in order, when one particular series is repeated every 4 trials, memory performance markedly improves over repetitions. This is known as the Hebb repetition effect. Eye movement recorded during the presentation of the to-be-remembered (TBR) information revealed that for the repeated sequence, participants fixated the location of the next TBR location before the actual presentation of the dot. The extent to which a TBR location was anticipated increased over repetition and occurred only for post-initial positions of the repeated sequence. Eye movement-based rehearsal activity was related to recall performance but not to sequence learning. The findings provide further evidence of anticipatory behavior in sequence learning and place key constraints on modeling the Hebb repetition effect.
在本研究中，作者通过对眼动和回忆表现的分析，揭示了驱动赫布重复效应的机制。在一个空间序列回忆任务中，要求按顺序记住一系列点，当每4次试验重复一个特定序列时，记忆表现会随着重复次数显著提高。这就是所谓的赫布重复效应。在呈现待记忆（TBR）信息期间记录的眼动显示，对于重复序列，参与者在实际呈现点之前就注视了下一个TBR位置。对TBR位置的预期程度随着重复次数增加，且仅在重复序列的初始位置之后出现。基于眼动的复述活动与回忆表现相关，但与序列学习无关。这些发现为序列学习中的预期行为提供了进一步证据，并对模拟赫布重复效应施加了关键限制。
