My PhD research focus is on fake identities in the online space, specifically social media, and how these fake identities present in the form of fake social media profiles. The main overall aim of the research is to investigate whether humans can accurately detect fake social media profiles and the processes they use to detect said profiles. The bulk of the current literature on fake social media profiles and how they can be detected is derived from computer science researchers, who have developed a series of algorithms or data bots (Efthimion et al., 2018; Van der Walt & Eloff, 2018) to detect and remove said profiles from social media platforms. However, there is a lack of research in this area from a psychological perspective, specifically in relation to what is actually analysed on the profile to conclude that it is fake (i.e. the profile characteristics, and who the people are behind the creation of such profiles). To investigate these issues, we seek to extend traditional research on social perception and 'realistic accuracy judgements' (Funder, 1999) to the domain of real and fake persona by applying a 'Turing test' style methodology.A total of three studies have been completed so far, all of which involved the same methodology: participants were required to view a series of fake and real Facebook profiles (screenshot images of the profile) and asked to judge the authenticity of the profile. The fake profiles were created specifically for this research using google images and photoshop. The information regarding the characteristics of the profiles that were manipulated were gathered from statistical reports regarding Facebook use, and the limited literature available on the topic. The real profiles were obtained from people known to the researcher to allow for them to be officially authenticated as real. Once participants had made their authenticity judgement of the profiles, they were asked to click on the areas of the profile they used when making their judgement. The purpose for this being that it would allow us to see which characteristics of the profile are used the most and thus may provide us answers as to which characteristics to look out for when judging a profile ourselves. Results from these three studies indicate that humans overall are not very accurate at judging the authenticity of social media profiles, a result that was predicted due to the larger amount of literature on human deception detection accuracy being around the level of chance (DePaulo, 2004). Additionally, consistently across each study, participants clicked the most on the photos on the profile, which came under the umbrella characteristic of Photo-Type, more than any other characteristic, suggesting an overreliance on the visual imagery presented on the profile and less so on the language used and items posted on the 'wall'. The fourth study that is currently ongoing is using the same methodology as the previous three, with the introduction of a different culture. The study will be comparing profiles from Western culture to Eastern cultures, specifically India. India is the country with the highest Facebook use around the world, with over 40 million users, and so is an area of great interest to this research. The main aim of this study is to analyse whether humans from one culture are more accurate at detecting fake profiles from another culture or from their own culture. Further, the aim is to also understand what constitutes a fake social media profile in another culture, i.e., what areas of the profile are they looking at/using when making their authenticity judgement. Do these areas differ from the results found previously from Western participants? To test this, the same methodology will be used alongside a series of new Indian fake profiles that have been created and real Indian profiles that are being sourced from International students at Lancaster University.

我的博士研究重点是在线空间中的假身份，特别是社交媒体，以及这些假身份如何以假社交媒体个人资料的形式存在。该研究的主要总体目标是调查人类是否可以准确地检测虚假的社交媒体资料以及他们用来检测所述资料的过程。目前关于虚假社交媒体配置文件以及如何检测它们的大部分文献都来自计算机科学研究人员，他们开发了一系列算法或数据机器人（Efthimion等人，2018;货车der Walt & Eloff，2018）检测并从社交媒体平台上删除所述配置文件。然而，在这一领域缺乏从心理学角度进行的研究，特别是在对个人资料进行实际分析以得出结论认为它是假的方面（即个人资料的特点，以及创建这种个人资料的人是谁）。为了研究这些问题，我们试图扩展传统的社会感知和“现实准确性判断”的研究（Funder，1999）应用“图灵测试”风格的方法学，将人物角色分为真实的和虚假的。迄今为止，共完成了三项研究，所有这些研究都涉及相同的方法：参与者被要求查看一系列假的和真实的Facebook个人资料（个人资料的截图图像），并被要求判断个人资料的真实性。这些虚假的个人资料是专门为这项研究使用谷歌图片和photoshop制作的。关于被操纵的个人资料特征的信息是从关于Facebook使用的统计报告和关于该主题的有限文献中收集的。这些真实的资料是从研究人员认识的人那里获得的，以便他们被正式认证为真实的。一旦参与者对个人资料的真实性做出判断，他们被要求点击他们在做出判断时使用的个人资料的区域。这样做的目的是，它将允许我们看到配置文件的哪些特征被使用得最多，从而可以为我们提供答案，即在我们自己判断配置文件时要注意哪些特征。这三项研究的结果表明，人类总体上在判断社交媒体资料的真实性方面并不十分准确，这一结果是由于大量关于人类欺骗检测准确性的文献所预测的（DePaulo，2004）。此外，在每项研究中，参与者在个人资料上的照片上点击最多，这些照片属于照片类型的保护伞特征，比任何其他特征都多，这表明过度依赖于个人资料上呈现的视觉图像，而不是使用的语言和张贴在“墙上”的物品。目前正在进行的第四项研究采用了与前三项研究相同的方法，但引入了不同的文化。这项研究将比较西方文化和东方文化，特别是印度文化的概况。印度是世界上Facebook使用率最高的国家，拥有超过4000万用户，因此也是这项研究非常感兴趣的地区。这项研究的主要目的是分析来自一种文化的人是否更准确地检测来自另一种文化或来自他们自己文化的虚假个人资料。此外，目的是了解在另一种文化中什么构成了虚假的社交媒体资料，即，当他们做出真实性判断时，他们正在查看/使用配置文件的哪些区域。这些领域与以前从西方参与者那里发现的结果不同吗？为了测试这一点，将使用相同的方法，同时使用一系列新的印度假档案，这些档案是从兰开斯特大学的国际学生那里创建的，以及真实的印度档案。
