Abstract

Background: What we think we see consists of models constructed in our brains, which may be constrained, limited and perhaps modified at a cerebral level. Patients may view their mirror image differently to how others and the clinical team view them. Understanding potential variations in perception between real and mirror images is important in clinical practice. The aims were to assess differences in self-perception between frontal facial and mirrored photographs, comparing the results with selfie photographs.

Methods: Facial photographs were taken by one investigator under standardized conditions for preclinical and clinical students. Each student took a selfie photograph at rest and smiling using his/her smartphone. A mirror image was generated for each image. Each student was shown his/her original and mirror image, without being informed which was which. For each pair of images, students were asked to choose which photograph they perceived as more attractive. A set of photographs of a male volunteer was shown to all participants, to choose either the original or mirror image as the more attractive.

Results: Most observers preferred the true image of the volunteer (P < 0.05), which may be evidence that most people prefer the true image of others, which is how they normally view them. Most observers preferred their own original photograph in frontal view at rest and smiling (P < 0.05), but preferred the mirror image of their selfie photograph at rest and smiling (P < 0.05).

Conclusions: Significant differences in perceptions of attractiveness between true and mirror-reversed frontal and selfie images were found. Observers preferred their image the way they view themselves in a mirror. The selfie is how other people view an individual. If a selfie is flipped horizontally, that is how an individual sees themselves in a mirror. Most observers preferred the mirror image of their selfie, which is how they would view themselves in a mirror.

正面面部图像与其镜像相比较的感知:手性、对象辨别及其与临床实践的相关性。
背景:我们认为我们所看到的是由我们大脑中构建的模型组成的,这些模型可能在大脑层面上受到约束、限制,甚至可能被修改。患者对自己镜像的看法可能与其他人和临床团队的看法不同。了解真实图像和镜像之间感知的潜在变化在临床实践中很重要。目的是评估正面面部照片和镜像照片之间的自我认知差异,并将结果与自拍照片进行比较。方法:由一名调查员在标准化条件下拍摄临床前和临床学生的面部照片。每个学生都用自己的智能手机拍了一张休息时微笑的自拍照。为每个映像生成镜像。每个学生都被展示了他/她的原始和镜像,但不知道哪个是哪个。对于每一对照片,学生们被要求选择他们认为更有吸引力的照片。研究人员向所有参与者展示了一组男性志愿者的照片,让他们在自己的照片或镜像中选择更有吸引力的一张。结果:大多数观察者更喜欢志愿者的真实照片(P)。结论:在真实照片和倒映的正面照片以及自拍照片之间,人们对吸引力的感知存在显著差异。观察者更喜欢自己的形象,就像他们在镜子里看到自己一样。自拍是别人对一个人的看法。如果自拍是水平翻转的,这就是一个人在镜子里看到自己的样子。大多数观察者更喜欢自己自拍的镜像,这是他们在镜子里看到自己的方式。
