越来越多的心理物理学证据表明，早期的视觉计算对刺激的拓扑特性很敏感，比如确定物体是否有洞。先前的研究已经证明，在有意识的知觉过程中，洞特征具有一定的优势。在本研究中，我们探讨了无意识知觉过程中是否存在对洞刺激的优先加工。通过应用连续闪光抑制范例，将目标逐渐引入到一只眼睛以与呈现给另一只眼睛的闪光的全对比度蒙德里安图案竞争。该方法保证了目标图像在初始感知阶段被抑制。我们比较了初始抑制的持续时间之间的刺激和没有孔的功能，发现孔刺激需要更少的时间比无孔刺激获得优势，对相同的抑制噪声。这些结果表明，孔特征可以在没有意识的情况下进行加工，并且在眼间竞争的抑制阶段存在对孔刺激的优先检测。
Mounting psychophysical evidence suggests that early visual computations are sensitive to the topological properties of stimuli, such as the determination of whether the object has a hole or not. Previous studies have demonstrated that the hole feature took some advantages during conscious perception. In this study, we investigate whether there exists a privileged processing for hole stimuli during unconscious perception. By applying a continuous flash suppression paradigm, the target was gradually introduced to one eye to compete against a flashed full contrast Mondrian pattern which was presented to the other eye. This method ensured that the target image was suppressed during the initial perceptual period. We compared the initial suppressed duration between the stimuli with and without the hole feature and found that hole stimuli required less time than no-hole stimuli to gain dominance against the identical suppression noise. These results suggest the hole feature could be processed in the absence of awareness, and there exists a privileged detection of hole stimuli during suppressed phase in the interocular rivalry.
