The facilitation of vection by "full-grass-water method"

Abstract

We report a new method of facilitating illusory self-motion perception (vection). Participants held either a full glass of water or a half glass of water while experiencing vection, and were instructed not to spill any of the water. Vection strength was indexed by its latency, duration, and magnitude. Results showed that vection was enhanced in the full glass of water condition. We want to name this method of vection facilitation “full-glass-water method”.
