Saccade-induced retrieval enhancement (SIRE) refers to the phenomenon that actively engaging in horizontal eye movements before recall enhances subsequent memory performance. This effect is thought to be the result of interhemispheric interactions stimulated by saccades. An alternative explanation is that saccades promote memory retrieval by improving top-down attention control. Thus, the mechanisms of SIRE are unclear, and the present meta-analysis quantitatively analysed the effect of saccades on memory performance and examined the mechanisms of SIRE. We searched "Web of Science," "PubMed," and "Springer" for peer-reviewed papers using the keywords "eye movements + memory" and "saccades + memory." Twenty-two papers were included in the final analysis. There was a significant facilitation of horizontal saccades on overall memory performance, with a pooled effect size (Cohen's ) of 0.45 ( < .001). However, the overall effect of vertical saccades was not significant ( = 0.1, = .14). Moderation analysis showed that the handedness of participants was a significant moderator of SIRE, with strongly right-handed individuals benefitting more from horizontal saccades than non-strongly right-handed individuals ( < .01). Horizontal saccades improved memory performance, particularly for strongly right-handed individuals. These results support the interhemispheric interaction hypothesis.
眼跳诱发的提取增强（SIRE）是指在回忆前主动进行水平眼动可增强后续记忆表现的现象。这种效应被认为是眼跳刺激的大脑两半球间相互作用的结果。另一种解释是，眼跳通过改善自上而下的注意力控制来促进记忆提取。因此，SIRE 的机制尚不清楚，本元分析定量分析了眼跳对记忆表现的影响，并检验了 SIRE 的机制。我们使用关键词“eye movements + memory”和“saccades + memory”在“Web of Science”、“PubMed”和“Springer”上搜索同行评审的论文。最终分析纳入了 22 篇论文。水平眼跳对整体记忆表现有显著的促进作用， pooled effect size (Cohen's )为 0.45（ < .001）。然而，垂直眼跳的总体效应不显著（ = 0.1， = .14）。调节分析表明，参与者的利手是 SIRE 的一个显著调节因素，强右利手个体从水平眼跳中获益大于非强右利手个体（ < .01）。水平眼跳改善了记忆表现，特别是对强右利手个体而言。这些结果支持了大脑两半球间相互作用的假说。
