The research, plainly
Gabriel Radvansky's experiments had people carry objects through virtual and real rooms. Simply passing through a doorway made them more likely to forget what they were carrying — the brain treats thresholds as event boundaries and closes the file on the previous scene.

What it means for events
Transitions aren't dead space; they're memory punctuation. A physical threshold between chapters of your event separates the memories — and skipping transitions smears everything into one forgettable blur.
Where to run it
Immersive & activation
Design literal thresholds — a corridor, a curtain, a light change — between acts. Each doorway starts a fresh memory file.
Conference flow
Move people between rooms for genuinely different modes: learn, commit, celebrate. The walk is doing cognitive work.
Virtual & broadcast
No hallways online — so build visual thresholds: full scene changes, not slide transitions.
