The recalibration of rotational locomotion

Rotational locomotion (i.e., turning in place) can be recalibrated by arran ging a situation in which one steps around at I speed but turns through the world at a different speed. After exposure to such a situation, people wil l show predictable changes if asked to look at a target, close their eyes, and turn to face it. In 5 experiments, this recalibration was shown to be a ttributable to 2 different mechanisms, one a sensory adaptation-like compon ent from simply turning in place for several minutes and the other a percep tual-learning-like component related to the discrepancy created by the rear rangement of optical flow and action.
