通过参与者的网络摄像头远程测量眼球运动有望成为实验室中面对面眼球追踪的一种有吸引力的方法。然而，目前还缺乏对幼儿远程网络眼动追踪与实验室眼动追踪进行比较的系统研究。我们报告了一项多实验室研究，在使用WebGazer.js和jsPsych的幼儿中比较了这两种测量方法。我们对18 - 27个月大的幼儿（N= 125）进行了远程测试，结果显示，基于网络的眼动追踪成功地捕捉到了基于目标的行动预测，尽管与实验室样本（N= 70）相比，目标导向的预期性注视的比例较低。正如预期的那样，基于网络的样本的流失率（42%）远远高于实验室样本（10%）。排除基于时间锁定凝视坐标和参与者的网络摄像头视频叠加在刺激上的视觉检查匹配的试验是减少数据噪声的重要预处理步骤。我们讨论使用这种远程网络为基础的方法，与其他当前的方法创新进行比较。我们的研究表明，基于网络的远程眼动追踪可以成为测试幼儿的有用工具，有助于招募更大、更多样化的样本；需要考虑的一个警告是更大的辍学率。
Measuring eye movements remotely via the participant's webcam promises to be an attractive methodological addition to in‐person eye‐tracking in the lab. However, there is a lack of systematic research comparing remote web‐based eye‐tracking with in‐lab eye‐tracking in young children. We report a multi‐lab study that compared these two measures in an anticipatory looking task with toddlers using WebGazer.js and jsPsych. Results of our remotely tested sample of 18‐27‐month‐old toddlers (N= 125) revealed that web‐based eye‐tracking successfully captured goal‐based action predictions, although the proportion of the goal‐directed anticipatory looking was lower compared to the in‐lab sample (N= 70). As expected, attrition rate was substantially higher in the web‐based (42%) than the in‐lab sample (10%). Excluding trials based on visual inspection of the match of time‐locked gaze coordinates and the participant's webcam video overlayed on the stimuli was an important preprocessing step to reduce noise in the data. We discuss the use of this remote web‐based method in comparison with other current methodological innovations. Our study demonstrates that remote web‐based eye‐tracking can be a useful tool for testing toddlers, facilitating recruitment of larger and more diverse samples; a caveat to consider is the larger drop‐out rate.
