摘 要：This pilot study tests the effects on individual performance of dyadic versus individual practice in a 3D virtual world (VW) home safety assessment. Sixty medical students in three conditions (dyadic spatially separated with paired avatars DPA; individual with avatar IND; and dyadic spatially together with single avatar DSA) participated in a geriatric home safety simulation. The participants, via avatars, conducted an assessment of physical hazards. Participants then worked individually in a separate 3D VW home assessment. Dyadic practice, spatially together with a single avatar (DSA), improved individual performance in the subsequent 3D VW home assessment.
