Embodied word learning in schools and sustained attention in virtual reality.

This study examined whether immersive virtual reality (VR) supports second-language vocabulary learning in school-aged children compared to passive computer-based training. Seventy-three Swedish middle-school students learned novel words by assembling objects in VR and by viewing object assembly on a computer screen in a crossover design. Word recall was tested after each condition, and individual differences in language aptitude and sustained attention were assessed. Overall, recall was higher after computer-based training than VR. However, sustained attention was the strongest predictor of learning outcomes, and the difference between conditions was (marginally) significant only for children with higher sustained attention. No VR behavioural measures (gaze, assembly time, rotation) explained learning outcomes. These findings suggest that VR may not universally enhance vocabulary learning but could benefit learners with specific attentional profiles. Further research should explore how VR design and training duration influence language acquisition in school settings.
