Polar angle asymmetries (PAAs), the differences in perceptual experiences and performance across different regions of the visual field are present in various paradigms and tasks of visual perception. Currently, research in this area is sparse, particularly regarding the influence of PAAs during perceptual illusions, highlighting a gap in visual cognition studies. We aim to fill this gap by measuring PAAs across the visual field during an illusion applied to test conscious vision widely. Motion-induced blindness (MIB) is an illusion when a peripheral target disappears from consciousness as the result of a continuously moving background pattern. During MIB we separately measured the average disappearance time of peripheral targets in eight equidistant visual field positions. Our results indicate a significant variation in MIB disappearance times and frequencies as a function of target location. Specifically, we found shorter and fewer disappearances along the cardinal compared to oblique directions, and along the horizontal compared to the vertical meridian. Our results suggest specific consistencies between visual field asymmetries and conscious visual perception.
极角不对称（PAA）是指在各种视觉感知范式和任务中，不同视野区域的感知体验和表现存在差异。目前，该领域的研究相对较少，特别是关于在感知错觉期间 PAA 的影响，这突显了视觉认知研究中的一个空白。我们旨在通过在广泛应用于测试意识视觉的错觉期间测量整个视野中的 PAA 来填补这一空白。运动致盲（MIB）是一种错觉，当一个外围目标由于连续运动的背景图案而从意识中消失时。在 MIB 期间，我们分别测量了八个等距视野位置中外围目标的平均消失时间。我们的结果表明，MIB 消失时间和频率随目标位置的变化而显著变化。具体来说，我们发现沿正方向比斜方向，以及沿水平方向比垂直子午线的消失时间更短，消失的次数更少。我们的结果表明，视野不对称性和有意识的视觉感知之间存在特定的一致性。
