We developed and validated a symptom scale that can be used to identify "trypophobia", in which individuals experience aversion induced by images of clusters of circular objects. The trypophobia questionnaire (TQ) was based on reports of various symptom types, but it nevertheless demonstrated a single construct, with high internal consistency and test-retest reliability. The TQ scores predicted discomfort from trypophobic images, but not neutral or unpleasant images, and did not correlate with anxiety. Using image filtering, we also reduced the excess energy at midrange spatial frequencies associated with both trypophobic and uncomfortable images. Relative to unfiltered trypophobic images, the discomfort from filtered images experienced by observers with high TQ scores was less than that experienced with control images and by observers with low TQ scores. Furthermore, we found that clusters of concave objects (holes) did not induce significantly more discomfort than clusters of convex objects (bumps), suggesting that trypophobia involves images with particular spectral profile rather than clusters of holes per se.
我们开发并验证了一种症状量表，可用于识别“密集恐惧症”，即个体对圆形物体集群图像产生厌恶感。密集恐惧症问卷（TQ）基于各种症状类型的报告，但它仍表现出单一的结构，具有高内部一致性和重测信度。TQ得分可预测对密集恐惧症图像的不适感，但对中性或不愉快图像则不然，且与焦虑无关。通过图像滤波，我们还降低了与密集恐惧症和令人不适图像相关的中频空间频率处的多余能量。相对于未滤波的密集恐惧症图像，高TQ得分观察者对滤波后图像的不适感低于对对照图像以及低TQ得分观察者的不适感。此外，我们发现凹形物体（孔洞）集群不会比凸形物体（凸起）集群引起明显更多的不适感，这表明密集恐惧症涉及具有特定光谱特征的图像，而非孔洞集群本身。
