Abstract: Apparent motion perception depends on both stimulus properties and attentional allocation, yet the role of the spatial distribution of attention remains unclear. The present study examined whether biases in attentional distribution systematically modulate bistable apparent motion perception. Using a motion quartet stimulus, three experiments manipulated attention along horizontal and vertical axes. In Experiments 1 and 2, attention was biased using elongated attentional cues. In Experiment 3, attention was manipulated via a secondary task while controlling for physical cue properties. Across all experiments, perceived motion direction was biased toward the attended axis: horizontal motion predominated under horizontal attention, whereas vertical motion predominated under vertical attention. These results demonstrate that the spatial distribution of attention plays a functional role in motion correspondence and highlight attention as a key factor shaping apparent motion perception.

コメント: 本研究では，注意の空間的な分布が仮現運動の知覚に与える影響を検討しています。3つの実験の結果，水平方向に注意を向けると水平運動が，垂直方向に注意を向けると垂直運動が知覚されやすくなることが示されました。この結果は，仮現運動の知覚が刺激の物理的な特性だけでなく，注意の空間的な配分によっても変化することを示しており，視覚運動の知覚における注意の重要性を明らかにしています。
