Research on emotional processes has been closely related to the use of emotional stimuli, promoting the development of different standardized sets of images. However, some kinds of images that would be relevant in clinical psychology research are not available, especially for small animal phobias. The aim of the present study is to validate a set of animal images that includes images of cockroaches, which are not present in the current sets of images. Two hundred and forty images depicting five types of animals (cockroaches, spiders, snakes, cats, and butterflies) were collected from online public domains. Four hundred and twenty-four participants (72.9% women) took part in the study rating the images in two affective dimensions (i.e., valence and arousal). Cockroach pictures were rated as significantly more unpleasant than pictures of spiders, snakes, butterflies, and cats. Moreover, results revealed that women rated cockroach, spider, and snake pictures as more negative than men did. Also, women in comparison with men rated cockroach images as more arousing. The results highlight the importance of using images of cockroaches, due to their high negative valence, which even exceeds that of snakes and spiders, the unpleasant animals typically used in phobic research. This set of images can be useful in research on small-animal phobias.

情绪过程的研究与情绪刺激的使用密切相关，促进了不同标准化图像集的发展。但是，某些与临床心理学研究相关的图像不可用，尤其是对于小动物恐惧症。本研究的目的是验证一组动物图像，其中包括当前图像集中不存在的蟑螂图像。从在线公共领域收集了 240 张描绘五种动物（蟑螂、蜘蛛、蛇、猫和蝴蝶）的图像。424 名参与者（72.9% 为女性）参与了这项研究，从两个情感维度（即效价和唤醒）对图像进行评分。蟑螂的照片被评为比蜘蛛的照片更令人不快，蛇、蝴蝶和猫。此外，结果显示，女性对蟑螂、蜘蛛和蛇图片的评价比男性更负面。此外，与男性相比，女性认为蟑螂图像更令人兴奋。结果突出了使用蟑螂图像的重要性，因为它们的负效价很高，甚至超过了通常用于恐惧症研究的令人不快的动物蛇和蜘蛛。这组图像可用于研究小动物恐惧症。这甚至超过了通常用于恐惧症研究的令人不快的动物蛇和蜘蛛。这组图像可用于研究小动物恐惧症。这甚至超过了通常用于恐惧症研究的令人不快的动物蛇和蜘蛛。这组图像可用于研究小动物恐惧症。
