众所周知，不愉快的图像会吸引我们的注意力。然而，这些图像引起的情绪的原因可能各不相同。Trypophobia是对聚集的物体的恐惧。最近的一项研究声称，这种恐惧症是由这些图像的特定功率谱引起的。在本研究中，我们测量眼跳轨迹，以研究具有特征功率谱的密集恐惧图像如何影响视觉注意。参与者的任务是在提示所指示的方向上进行扫视。在0 ms、150 ms和450 ms时，四个具有不同情绪内容的无关图像被呈现为线索图像起始时间的外围干扰物。不相关的图像包括密集恐怖，恐惧或中性场景。由密集恐惧图像引起的扫视轨迹偏差的存在表明，完整的密集恐惧图像将注意力集中在它们的位置上。此外，当图像相位混乱时，眼跳曲线远离密集恐惧图像，表明密集恐惧功率谱也触发注意捕获，这是微弱的，然后导致抑制。这些发现表明，不仅功率谱特征，而且密集恐惧图像的要点影响注意部署。
It is known that unpleasant images capture our attention. However, the causes of the emotions evoked by these images can vary. Trypophobia is the fear of clustered objects. A recent study claimed that this phobia is elicited by the specific power spectrum of such images. In the present study, we measured saccade trajectories to examine how trypophobic images possessing a characteristic power spectrum affect visual attention. The participants' task was to make a saccade in the direction that was indicated by a cue. Four irrelevant images with different emotional content were presented as periphery distractors at 0 ms, 150 ms, and 450 ms in terms of cue-image onset asynchrony. The irrelevant images consisted of trypophobic, fearful, or neutral scenes. The presence of saccade trajectory deviations induced by trypophobic images suggest that intact trypophobic images oriented attention to their location. Moreover, when the images were phase scrambled, the saccade curved away from the trypophobic images, suggesting that trypophobic power spectra also triggered attentional capture, which was weak and then led to inhibition. These findings suggest that not only the power spectral characteristics but also the gist of a trypophobic image affect attentional deployment.
