Contexto
What changed: Instructional videos were presented at accelerated playback rates ranging from 1.1x to 2.5x speed. Comparison: Instructional videos watched at normal 1.0x speed. Limits: Substantial heterogeneity across studies, potential publication bias detected via Egger's test, and samples largely restricted to university student laboratory settings.
