Abstract

Recognition memory, the ability to recognise previously encountered information, correlates with pupil diameter changes during the recognition period. This physiological response, known as the pupil old/new effect, generally reflects the variation in pupil dilation when encountering previously studied (old) stimuli compared to new stimuli. To develop a more precise understanding of the pupil old/new effect, we conducted a meta-analysis of 17 eye-tracking experiments (across 12 articles spanning from 2008 to 2023) involving 560 healthy adults with a mean age of 22.31 years. Analysis of publication bias showed a rather low risk of bias in the selected articles. The main meta-analysis revealed a significant and large pooled pupil old/new effect (Cohen's d_z = 0.73, 95% CI [0.50, 0.95]). Further analysis of moderators showed that the number of participants included in the experiments and the criteria for selecting trials (only correct trials vs. all trials) had a significant impact on the meta-analytic results. In general, the analyses revealed a robust pupil old/new effect across all selected articles. This finding underscores its potential utility as a marker of recognition memory across different stimuli type, and various experimental designs.

瞳孔新旧效应作为识别记忆的客观衡量标准：对 17 项眼球跟踪实验的荟萃分析。

识别记忆，即识别以前遇到的信息的能力，与识别期间瞳孔直径的变化有关。这种生理反应被称为瞳孔新旧效应，一般反映了在遇到以前学习过的（旧的）刺激与新刺激时瞳孔放大的变化。为了更准确地理解瞳孔新旧效应，我们对 17 项眼球追踪实验（涉及 12 篇文章，时间跨度从 2008 年到 2023 年）进行了荟萃分析，这些实验涉及 560 名健康成年人，他们的平均年龄为 22.31 岁。发表偏倚分析表明，所选文章的偏倚风险较低。主要的荟萃分析表明，瞳孔新旧效应显著且较大（Cohen's dz = 0.73，95% CI [0.50，0.95]）。对调节因子的进一步分析表明，实验中的参与者人数和试验选择标准（仅正确试验与所有试验）对元分析结果有显著影响。总的来说，分析结果表明，在所有选定的文章中，瞳孔新旧效应都很明显。这一发现强调了瞳孔旧/新效应作为识别记忆标记的潜在作用，可以跨越不同的刺激类型和各种实验设计。

期刊介绍： Memory publishes high quality papers in all areas of memory research. This includes experimental studies of memory (including laboratory-based research, everyday memory studies, and applied memory research), developmental, educational, neuropsychological, clinical and social research on memory. By representing all significant areas of memory research, the journal cuts across the traditional distinctions of psychological research. Memory therefore provides a unique venue for memory researchers to communicate their findings and ideas both to peers within their own research tradition in the study of memory, and also to the wider range of research communities with direct interest in human memory.
