Exposure of erect subjects to stationary tilted visual frames or rooms produces only up to 20\u00b0 of illusory tilt. But, in studies using static tilted rooms, subjects remained erect and the body axis was not aligned with the room. We have revealed a new class of disorientation illusions that occur in many subjects when placed in a 90\u00b0 or 180\u00b0 tilted room containing polarised objects (familiar objects with tops and bottoms). For example, supine subjects looking up at a wall of the room feel upright in an upright room and their arms feel weightless when held out from the body. We call this the levitation illusion. We measured the incidence of 90\u00b0 or 180\u00b0 reorientation illusions in erect, supine, recumbent, and inverted subjects in a room tilted 90\u00b0 or 180\u00b0. We report that reorientation illusions depend on the displacement of the visual scene rather than of the body. However, illusions are most likely to occur when the visual and body axes are congruent. When the axes are congruent, illusions are least likely to occur when subjects are prone rather than supine, recumbent, or inverted.<\/jats:p>","DOI":"10.1068\/p3106","type":"journal-article","created":{"date-parts":[[2002,8,24]],"date-time":"2002-08-24T17:28:38Z","timestamp":1030210118000},"page":"583-600","source":"Crossref","is-referenced-by-count":60,"title":["Visually
