Grounding together: Shared reality and cleansing practices.

We propose that cleansing behaviors and other acts of separation or connection have more powerful effects when they are grounded in shared practices - in a shared reality. We conceptualize sensorimotor and shared reality effects as synergistic. Most potent should be physical behaviors performed collectively as a shared practice (e.g., communal bathing), grounded both in sensorimotor experience and in shared reality.
