125 babies tested by 15 labs

33 authors from 11 countries on Infancy publication

In this multi-lab methodological project, we try to validate an open source, web-based, eye-tracking method for research on cognitive development in young children. More specifically, we evaluate whether this method, which is based on WebGazer.js (Papoutsaki et al., 2016) and jsPsych (de Leeuw, 2015), is comparable to lab-based eye-tracking. Therefore, we aim to replicate findings of an in-lab paradigm of the ManyBabies2 project, which revealed spontaneous goal-directed action anticipation in toddlers using commercial eye-tracking systems (Schuwerk, Kampis et al., 2021).
