During the recent pandemic, it became necessary to adapt lab-based studies to online experiments. To investigate the impact of online testing on the quality of data, we focus on three paradigms widely used in infant research: a word recognition task using the Intermodal Preferential Looking Paradigm, a word learning task using the Switch task, and a language assessment tool (WinG) where children identify a target word amongst a set of picture cards. Our results for synchronous and asynchronous studies provide support for the robustness of online testing. In Experiment 1, robust word recognition was found in 24-month-old toddlers. In Experiment 2, 17-month-old infants consistently learned a new word. Finally, Experiment 3 demonstrated that 19- to 26-month-old children performed well on a language assessment test administered online. Overall, effect sizes or language scores were found to be higher than in lab-based studies. These experiments point to promising possibilities for reaching out to families around the world.

将语言发展研究范式适应在线测试：来自幼儿偏好观察、单词学习和词汇评估的数据


在最近的大流行期间，有必要将实验室研究改为在线实验。为了研究在线测试对数据质量的影响，我们重点关注婴儿研究中广泛使用的三种范式：使用联运优先查看范式的单词识别任务、使用 Switch 任务的单词学习任务以及语言评估工具（ WinG），孩子们可以在一组图片卡中识别目标单词。我们的同步和异步研究结果为在线测试的稳健性提供了支持。在实验 1 中，24 个月大的幼儿发现了强大的单词识别能力。在实验 2 中，17 个月大的婴儿持续学习一个新单词。最后，实验 3 表明 19 至 26 个月大的儿童在在线语言评估测试中表现良好。总体而言，效果大小或语言分数高于实验室研究。这些实验表明了接触世界各地家庭的有希望的可能性。
