Abstract

近年,3次元構造の復元過程に頭部運動や眼球運動情報などの網膜外情報が影響を与えるという報告が見られるようになってきた.これらの網膜外情報の利用は人間の発達過程を経て成立してきたと考えられる一方で,新奇な操作行動についても同様の関係が存在・成立するのか,もし成立するのであればどのような過程を経るのかは明らかではない.本研究では操作行動が実験では多義的な3次元構造の解釈をもつ2D optic flowの解釈に与える影響と,その成立過程について検討を行った.実験ではタッチパネル上での被験者のペンの移動に同期して3次元空間内を移動するドット刺激が呈示された.実験の結果,セッションが進むにつれて被験者の操作に同期した奥行き運動を知覚する頻度が増加した.このとき,被験者が操作した刺激の移動だけを自動的に呈示した条件や,腕の移動と奥行きの関係を反転させたセッションでは奥行きを知覚する頻度が減少しており,操作の重要性が示唆された.

It has recently become clear that the preparation and execution of a variety of motor actions can have an effect on three-dimensional perceptual processes. These effects might be caused by the sorts of action-perception relationships engendered by active locomotion. It is unclear, however, whether such an effect can be seen in the novel action-perception relationship. In the present study, we investigated the effect of a novel manual action on 3D interpretation for an ambiguous 2D optic flow field, and the formation of the effect. A stimulus was a slanted plane formed by white dots. The stimulus synchronously moved and rotated in depth with subjects' hand movement on a tablet panel. Subjects answered the direction of its axis of rotation. The results showed that the frequency of perception with depth movement synchronized with subjects' manual movement increased as sessions proceeded. The frequency, however, was decreased when subjects were displayed the replay of a previous session without manual movement and when the relation between subjects' movement and the direction of stimulus movement was reversed They indicate that the visual system used the association between manual movements and object movements formed during the experiment.
