Abstract

視野の大部分を占める領域で視覚刺激が均一に運動するのを観察した場合に,静止しているはずの自己の身体が視覚刺激とは反対方向に運動して知覚される.この現象は自己身体誘導運動知覚(もしくはベクション)と呼ばれ,視覚情報が自己定位に大きな影響を及ぼすことの根拠として古くから検討の対象となっている.今回の実験では,これまで検討されることの少なかった視覚刺激の付加的属性の同期的な変化がベクションに及ぼす影響を検討し,視覚刺激の同期的な付加振動がベクションを増強し,刺激色の同期的変化が反対にベクション強度を抑制することを示した.前者には視覚刺激の剛体性知覚が,後者には色の恒常性に基づく照明光変化の知覚が関与していることが示唆された.

Uniform motion of a visual stimulus which occupies larger area of observer's visual field can induce illusory perception of self-motion in the direction opposite to the visual motion. This perceptual phenomenon is called visually induced self-motion perception (or veciton), and has been investigated as a strong evidence which indicates that visual information can strongly affect self-orientation. The current research was aimed to investigate the effects of coherent modulations of additional stimulus attributes which has been ignored by the vection studies. Three psychophysical experiments revealed that coherent stimulus oscillation enhances self-motion perception, whereas coherent modulation of the stimulus color inhibits vection. Rigidity perception of the stimulus pattern can explain the former, and perceived modulation of illumination would be responsible for the latter.
