q1 i? The authors propose that experimenter-controlled video segmentation, rather than learner-controlled pacing, may have obstructed memory encoding in both conditions. → Mavilidi 2026

Mavilidi, M.F., Paas, F., Zou, L., Lubans, D.R., Mokhtari, L., Schmidt, M., Castro Alonso, J.C., Ng, R., & Bennet, S. (2026). Effects of Videos with Whole-Body Movements on Young Children's Geography Learning. npj Science of Learning. https://doi.org/10.1038/s41539-026-00408-8

q1 · i? · causal · r2

Authors' post hoc interpretation (type e) in the Discussion, citing eye-tracking evidence that frequent user-driven content shifts in short-video watching may impair event segmentation needed for continuous memory encoding, while personalised videos or static images did not show this effect.

"it is possible that the video segmentation occurring by the experimenters, who controlled the pace and timing of each video, obstructed children's memory encoding."
