Our objective was to determine whether the influence of linear perspective cues and texture gradients in the perceptual rescaling of stimulus size transfers from one eye to the other. In experiment 1, we systematically added linear perspective cues and texture gradients in a background image of the corridor illusion. To determine whether perceptual size rescaling takes place at earlier or later stages, we tested how the perceived size of top and bottom rings changed under binocular (rings and background presented to both eyes), monocular (rings and background presented to the dominant eye only), and dichoptic (rings and background presented separately to the dominant and nondominant eyes, respectively) viewing conditions. We found differences between viewing conditions in the perceived size of the rings when linear perspective cues, but not texture gradients, were presented. Specifically, linear perspective cues produced a stronger illusion under the monocular compared to the dichoptic viewing condition. Hence, there was partial interocular transfer from the linear perspective cues, suggesting a dominant role of monocular neural populations in mediating the corridor illusion. In experiment 2, we repeated similar procedures with a more traditional Ponzo illusion background. Contrary to findings from experiment 1, there was a full interocular transfer with the presence of the converging lines, suggesting a dominant role of binocular neural populations. We conclude that higher order visual areas, which contain binocular neural populations, are more involved in the perceptual rescaling of size evoked by linear perspective cues in the Ponzo compared to the corridor illusion.

我们的目标是确定线性透视线索和纹理梯度在刺激大小的感知重新缩放中的影响是否从一只眼睛转移到另一只眼睛。在实验 1 中，我们在走廊错觉的背景图像中系统地添加了线性透视提示和纹理渐变。为了确定感知大小重新缩放是否发生在早期或后期阶段，我们测试了在双目（双眼呈现环和背景）、单眼（仅优势眼呈现环和背景）下，顶部和底部环的感知大小如何变化，和二分光（分别呈现给优势眼和非优势眼的环和背景）观看条件。当线性透视提示时，我们发现观察条件在环的感知大小方面存在差异，但没有呈现纹理渐变。具体来说，与双视观察条件相比，线性透视线索在单眼下产生了更强的错觉。因此，来自线性透视线索的部分眼间转移，表明单眼神经群在介导走廊错觉中的主导作用。在实验 2 中，我们使用更传统的庞佐错觉背景重复了类似的程序。与实验 1 的结果相反，在存在会聚线的情况下存在完全的眼间转移，表明双眼神经群体的主要作用。我们得出结论，与走廊错觉相比，包含双目神经群的高阶视觉区域更多地参与由 Ponzo 中的线性透视线索引起的大小的感知重新缩放。
