在组织感知时，人类视觉系统利用视觉输入中的噪声来感知地分组相关的图像元素。简单的刺激，可以感知分组的基础上，例如通过形成一个虚幻的轮廓，在进入视觉意识的竞争优势。在这里，我们表明，从视觉环境中的复杂的，有意义的对象的相对定位所产生的干扰也调节视觉意识。使用连续的闪光抑制，我们发现，根据真实世界的空间位置（例如，桌子上方的灯）比以不规则配置示出的相同对象对（例如，灯上方的桌子）。这种优势是特定的直立刺激和取消刺激反转，这意味着它不反映物理刺激混淆或简单的图像元素的分组。因此，对环境中物体的空间结构的认识塑造了意识知觉的内容。
In organizing perception, the human visual system takes advantage of regularities in the visual input to perceptually group related image elements. Simple stimuli that can be perceptually grouped based on physical regularities, for example by forming an illusory contour, have a competitive advantage in entering visual awareness. Here, we show that regularities that arise from the relative positioning of complex, meaningful objects in the visual environment also modulate visual awareness. Using continuous flash suppression, we found that pairs of objects that were positioned according to real-world spatial regularities (e.g., a lamp above a table) accessed awareness more quickly than the same object pairs shown in irregular configurations (e.g., a table above a lamp). This advantage was specific to upright stimuli and abolished by stimulus inversion, meaning that it did not reflect physical stimulus confounds or the grouping of simple image elements. Thus, knowledge of the spatial configuration of objects in the environment shapes the contents of conscious perception.
