Abstract

The study of infant gaze has long been a key tool for understanding the developing mind. However, labor-intensive data collection and processing limit the speed at which this understanding can be advanced. Here, we demonstrate an asynchronous workflow for conducting violation-of-expectation (VoE) experiments, which is fully "hands-off" for the experimenter. We first replicate four classic VoE experiments in a synchronous online setting, and show that VoE can generate highly replicable effects through remote testing. We then confirm the accuracy of a state-of-the-art gaze annotation software, iCatcher+ in a new setting. Third, we train parents to control the experiment flow based on the infant's gaze. Combining all three innovations, we then conduct an asynchronous automated infant-contingent VoE experiment. The hands-off workflow successfully replicates a classic VoE effect: infants look longer at inefficient actions than efficient ones. We compare the resulting effect size and statistical power to the same study run in-lab and synchronously via Zoom. The hands-off workflow significantly reduces the marginal cost and time per participant, enabling larger sample sizes. By enhancing the reproducibility and robustness of findings relying on infant looking, this workflow could help support a cumulative science of infant cognition. Tools to implement the workflow are openly available. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

用于婴儿观察时间实验的非同步、无需动手的工作流程。

长期以来，婴儿凝视研究一直是了解心智发育的重要工具。然而，劳动密集型的数据收集和处理限制了这种理解的推进速度。在这里，我们展示了一种进行违背期望（VoE）实验的异步工作流程，实验者完全可以 "放手不管"。我们首先在同步在线环境中复制了四个经典的 VoE 实验，并证明 VoE 可以通过远程测试产生高度可复制的效果。然后，我们在新的环境中确认了最先进的注视标注软件 iCatcher+ 的准确性。第三，我们训练父母根据婴儿的注视来控制实验流程。结合所有三项创新，我们进行了异步自动婴儿视情 VoE 实验。放手式工作流程成功复制了经典的VoE效应：婴儿看低效动作的时间比看高效动作的时间长。我们将得出的效应大小和统计能力与实验室内和通过 Zoom 同步进行的相同研究进行了比较。无需动手的工作流程大大降低了每位参与者的边际成本和时间，从而实现了更大的样本量。通过提高依赖于婴儿观察的研究结果的可重复性和稳健性，该工作流程有助于支持婴儿认知科学的积累。实施该工作流程的工具可公开获取。(PsycInfo Database Record (c) 2024 APA，保留所有权利）。

期刊介绍： Developmental Psychology ® publishes articles that significantly advance knowledge and theory about development across the life span. The journal focuses on seminal empirical contributions. The journal occasionally publishes exceptionally strong scholarly reviews and theoretical or methodological articles. Studies of any aspect of psychological development are appropriate, as are studies of the biological, social, and cultural factors that affect development. The journal welcomes not only laboratory-based experimental studies but studies employing other rigorous methodologies, such as ethnographies, field research, and secondary analyses of large data sets. We especially seek submissions in new areas of inquiry and submissions that will address contradictory findings or controversies in the field as well as the generalizability of extant findings in new populations. Although most articles in this journal address human development, studies of other species are appropriate if they have important implications for human development. Submissions can consist of single manuscripts, proposed sections, or short reports.
