密集恐惧症是一种常见但不寻常的恐惧症，是由观看许多聚集的物体引起的。之前的研究表明，这种密集恐惧症是由图像的特定功率谱引起的；这个想法尚未得到充分的实证研究。在本研究中，我们使用突破性连续闪光抑制（b-CFS）来阐明密集恐惧症图像是否影响视觉意识的获取，以及密集恐惧症图像的哪些特征有助于快速获取意识。在 b-CFS 范例中，呈现给一只眼睛的动态掩蔽图案会抑制呈现给另一只眼睛的目标图像。参与者的任务是通过镜面立体镜指示目标图像出现在二分视显示器中的位置。目标图像由密集恐惧症、恐惧相关、集群或中性图像组成。密集恐惧症图像比其他类型的图像更快地进入人们的意识。然而，密集恐惧症图像的相位扰乱版本并未显示出图像类型之间的任何差异，这表明密集恐惧症功率谱本身并不影响获得意识。此外，没有 CFS 的相位置乱密集恐惧图像往往比相位置乱的恐惧图像和中性图像更早被检测到。这些发现表明，密集恐惧症功率谱可能会影响感知后处理，例如反应产生。
Trypophobia is a common but unusual phobia that is induced by viewing many clustered objects. Previous studies suggested that this trypophobia is caused by the specific power spectrum of the images; this idea has not been fully investigated empirically. In the present study, we used breaking continuous flash suppression (b-CFS) to clarify whether the trypophobic images affect access to visual awareness, and what features of trypophobic images contribute to rapid access of awareness. In the b-CFS paradigms, a dynamic masking pattern presented to one eye suppresses the target images shown to the other eye. The participants' task was to indicate where the target image appeared in a dichoptic display through a mirror stereoscope. The target images consisted of trypophobic, fear-related, clusters or neutral images. The trypophobic images emerged into awareness faster than the other types of images. However, the phase-scrambled versions of the trypophobic images did not show any differences across the image types, suggesting that the trypophobic power spectra themselves did not affect access to awareness. Moreover, the phase scrambled trypophobic images without CFS tended to be detected earlier than the phase scrambled fearful and neutral images. These findings indicate that trypophobic power spectra might affect post-perceptual processing, such as response production.
