我们开发并验证了一种症状量表，可以用来识别色觉恐惧症，在这种情况下，个体会体验到对圆形物体集群的图像所引起的厌恶。锥虫恐惧症问卷(TQ)是基于各种症状类型的报告，但它仍然显示出单一的结构，具有很高的内部一致性和重测可靠性。TQ分数预测了恐胰症图像的不适感，但不能预测中性或令人不快的图像，而且与焦虑没有关联。通过使用图像过滤，我们还减少了与恐胰症和不舒服图像相关的中端空间频率的过剩能量。与未过滤的恐惧症图像相比，TQ分数高的观察者从过滤的图像中感受到的不适感比对照图像和TQ分数低的观察者所感受到的要少。此外，我们发现，成群的凹形物体(洞)并不比成群的凸起物体(凸起)引起明显更多的不适感，这表明恐惧症涉及到具有特定光谱轮廓的图像，而不是空洞集群本身。
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.
