婴儿在线数据收集为发展研究带来了特殊的机遇和挑战。在婴儿研究中最流行的方法之一是眼动追踪，它已被广泛应用于实验室环境中，以评估认知发展。技术进步现在允许对包括婴儿在内的各种人群进行在线眼动跟踪。然而，在线婴儿眼动追踪的准确性和可靠性仍有待全面评估。到目前为止，还没有研究直接比较基于网络摄像头和实验室的婴儿眼动跟踪数据，类似于成人的数据。目前的研究提供了一个直接的比较，在实验室和基于网络摄像头的眼动追踪数据，从婴儿谁完成了相同的看时间范式在两个不同的设置（在实验室或在线在家里）。我们评估了4 - 6个月大的婴儿（n = 38）在眼动追踪任务，测量检测视听障碍。基于网络摄像头和实验室内的眼动追踪数据在眼动追踪和视频数据质量、婴儿的观看行为和实验效果方面进行了比较。结果显示，在实验室和在线设置的技术问题的频率和参与者流失率之间没有差异。尽管在线帧速率和分辨率较低，但在完整性和亮度方面，两种设置之间的视频数据质量相当。眼动追踪数据的质量在实验室比在线更高，除了在相对样本丢失的情况下。在两种设置下，眼动跟踪记录的注视数据量均显著低于视频记录。在有效的试验中，眼动追踪和视频数据捕捉到了婴儿的观看行为，无论设置如何。尽管婴儿眼动追踪在实验环境中面临着共同的挑战，但我们的研究结果表明，有必要进一步提高婴儿在线眼动追踪的精度。总的来说，在线眼动追踪是一种很有前途的评估婴儿凝视行为的工具，但需要仔细的数据质量控制。这两个样本的人口构成与一般人群的护理人员教育不同：我们的样本包括教育水平高于平均水平的护理人员，挑战了在线研究本身将覆盖更多样化人群的概念。
Online data collection with infants raises special opportunities and challenges for developmental research. One of the most prevalent methods in infancy research is eye-tracking, which has been widely applied in laboratory settings to assess cognitive development. Technological advances now allow conducting eye-tracking online with various populations, including infants. However, the accuracy and reliability of online infant eye-tracking remain to be comprehensively evaluated. No research to date has directly compared webcam-based and in-lab eye-tracking data from infants, similarly to data from adults. The present study provides a direct comparison of in-lab and webcam-based eye-tracking data from infants who completed an identical looking time paradigm in two different settings (in the laboratory or online at home). We assessed 4-6-month-old infants (n = 38) in an eye-tracking task that measured the detection of audio-visual asynchrony. Webcam-based and in-lab eye-tracking data were compared on eye-tracking and video data quality, infants’ viewing behavior, and experimental effects. Results revealed no differences between the in-lab and online setting in the frequency of technical issues and participant attrition rates. Video data quality was comparable between settings in terms of completeness and brightness, despite lower frame rate and resolution online. Eye-tracking data quality was higher in the laboratory than online, except in case of relative sample loss. Gaze data quantity recorded by eye-tracking was significantly lower than by video in both settings. In valid trials, eye-tracking and video data captured infants’ viewing behavior uniformly, irrespective of setting. Despite the common challenges of infant eye-tracking across experimental settings, our results point toward the necessity to further improve the precision of online eye-tracking with infants. Taken together, online eye-tracking is a promising tool to assess infants’ gaze behavior but requires careful data quality control. The demographic composition of both samples differed from the generic population on caregiver education: our samples comprised caregivers with higher-than-average education levels, challenging the notion that online studies will per se reach more diverse populations.
