The relation between working memory capacity (WMC) and baseline pupil diameter was examined. Participants (N = 341) performed several WMC tasks and baseline pupil diameter was measured in a dark room with a black background screen. The results indicated a weak and non-significant correlation between WMC and baseline pupil diameter consistent with some prior research. A meta-analysis of available studies (k = 26; N = 4356) similarly indicated a weak and non-significant correlation between WMC and baseline pupil diameter. Moderator analyses indicated that the primary moderator responsible for heterogeneity across studies was where the study was conducted. Studies from one laboratory tend to demonstrate a significant positive correlation, whereas other laboratories have yet to demonstrate the correlation. Broadly, the results suggest that the correlation between WMC and baseline pupil diameter is weak and not particularly robust.
研究了工作记忆容量（WMC）与基线瞳孔直径之间的关系。参与者（N = 341）完成了多项WMC任务，并在一个带有黑色背景屏幕的暗室中测量了基线瞳孔直径。结果表明，WMC与基线瞳孔直径之间存在微弱且不显著的相关性，这与之前的一些研究一致。对现有研究的荟萃分析（k = 26；N = 4356）同样表明，WMC与基线瞳孔直径之间存在微弱且不显著的相关性。调节因素分析表明，造成各研究之间异质性的主要调节因素是研究的开展地点。来自一个实验室的研究往往显示出显著的正相关，而其他实验室尚未证实这种相关性。总体而言，结果表明WMC与基线瞳孔直径之间的相关性较弱，且不太稳定。
