Unconscious motor control that conflicts with conscious awareness.

During my recent Europe vacation, on stepping onto an escalator in the Munich metro that I knew was stopped, I noticed that odd sensation accompanied by clumsy movements that is probably also familiar to you, as if my motor behavior and sensations were being guided by a “phantom” of a moving escalator. Fukui et al. show that this is the consequence of an unconscious automatic habitual motor program cued by the escalator itself. Their results suggest a dissociation between conscious awareness and subconscious motor control: the former makes us perfectly aware of the current environmental situation, but the latter automatically emerges as a result of highly habituated visual input no matter how unsuitable the motor control is.

I'd never really thought about it, but I've always liked going up and down static escalators for that slight woozy feeling it gives you.
