The Hebb repetition effect is a phenomenon in which a repeated presentation of the same list increases the performance in immediate serial recall. This provided the theoretical basis for a core assumption of the Atkinson and Shiffrin model regarding information transfer from short-term memory to long-term memory. The Hebb repetition effect was originally reported for the verbal domain, but subsequent studies found similar phenomena using visuospatial paradigms, for example, in serial-order memory for dot locations. The present study examined in two experiments the effects of presentation timing of nine spatial locations on Hebb repetition learning. In Experiment 1, the Hebb repetition effects were observed for spatial locations with constant timing presentation as well as temporal grouping presentation. In the latter condition, all lists were presented with the same temporal structure, that is, temporal pauses were inserted after the third and sixth serial positions. This manipulation led to a better recall performance in comparison with the constant presentation, but did not interact with the repetition. In Experiment 2, the Hebb list was presented with a different temporal structure in every repetition in the random-grouping condition. Although this manipulation is known to eliminate or weaken the Hebb effect in the verbal domain, we observed stable repetition effects in this experiment. This suggests that there might be some domain-specific mechanisms in Hebb repetition learning. These results may facilitate the development of theories of the relationship between short-term and long-term memory.
赫布重复效应是一种现象，即在同一列表重复呈现会增加即时序列回忆的表现。这为阿特金森和希夫林模型关于从短期记忆到长期记忆的信息转移的核心假设提供了理论基础。赫布重复效应最初是在言语领域报告的，但随后的研究使用视空间范式发现了类似的现象，例如，在点位置的序列顺序记忆中。本研究在两项实验中检验了九个空间位置呈现时间对赫布重复学习的影响。在实验 1 中，观察到了空间位置的赫布重复效应，具有恒定的呈现时间和时间分组呈现。在后一种情况下，所有列表都以相同的时间结构呈现，即，在第三个和第六个序列位置之后插入时间停顿。与恒定呈现相比，这种操作导致了更好的回忆表现，但与重复没有交互作用。在实验 2 中，在随机分组条件下，每个重复的赫布列表呈现不同的时间结构。尽管这种操作已知会在言语领域消除或削弱赫布效应，但我们在这个实验中观察到了稳定的重复效应。这表明赫布重复学习中可能存在一些特定于领域的机制。这些结果可能有助于发展短期和长期记忆之间关系的理论。
