Deception has long been of interest to humans, but only recently has the neuroscience of deception started. Similarly, lie-detection, as an applied aspect of the study of deception, has long been studied but only with the advent of imaging techniques and the development of the neuroscience of deception has it become possible to develop techniques based on scanningour brains. Currently, both areas suffer from methodological and philosophical problems. As an applied science fMRI lie-detection has greater issues to deal with, specifically legal and ethical issues. Despite interesting results, implicating frontal regions as the neural correlates of deception, the neuroscience of deception need better designs and more study to be able to draw any general inferences. By its nature fMRI lie-detection suffers greatly from this, and additional problems concerning privacy and legality make it seem too early to implement it incourt or anywhere, as stated by many scientists. On the other hand the technology already exists and is likely to be used.

The current study examined the relationship between psychopathic personality traits and various forms of deception. Through the use of the Elemental Psychopathy Assessment to measure psychopathy, and several different assessment tools to measure deception, including the Multidimensional Deception Inventory (MDI), the relationship between psychopathic personality traits and deception was examined. Using an undergraduate sample of 261 participants at a large research university in the Southeastern United States, the relationship between the aforementioned constructs was explored. Results indicated that the overarching personality traits of Antagonism and Disinhibition were positively related to multiple dimensions of lying behavior. Frequency of lies told, Duping Delight (lies told for enjoyment), and lies told for personal gain/impression management and to avoid disclosing pertinent information were positively related to both Antagonism and Disinhibition. Results point to the need for future study in this area, as limited previous research has looked at the overlap between psychopathic personality traits and deception.

Today's world is an interconnected global village. Communication and business transactions are increasingly conducted in non-native languages. Literature suggests that biases are present when communicating in non-native languages; that a truth bias is present in first language communication, and a lie bias in second language communication. Less than 10% of South Africa's population identifies with English, the lingua franca of the country, as a first language. Not much research in the presence of bias in second language communication has been published in the South African multi-lingual context. This study evaluated the presences of bias within deception frameworks such as the Truth Default State and the veracity effect. This study investigated whether deception detection can be improved by modifying the conditions under which statements are given by placing statement providers under cognitive load. The accuracy of veracity judgment language profiling software, LIWC2015, using published deception language profiles was compared against the results of the participating veracity judges. Results of the study were mixed. It was consistent with extant literature in a presence of a truth bias overall, but mixed in terms of a lie bias. The results supported the Truth Default Theory and veracity effect frameworks. LIWC2015 performed marginally better than human judges in evaluating veracity.

This dissertation was performed with the aim of understanding more about how people interact with and deceive one another in an online context. To build that understanding, the study was motivated by five research questions: (1) How do users experience the process of misrepresenting themselves to others? (2) How do users present themselves in online contexts in which they may not feel comfortable with portraying themselves fully? (3) How do perceived norms and expectations within groups inform users’ self-presentations? (4) How do users’ perceptions of who will view their information impact self-representation? (5) How do perceived affordances impact how users feel they can engage in deceptive practices? To explore and answer these questions, 27 interviews were conducted via the social networking platform Discord with members of the r/Fantasy server. The findings from the research show that how users perceive the potential audiences they have in a group setting is impacted by what they perceive the affordances of the platform to be. In turn, these perceptions influence what users care to share about themselves and how and if they engage in deceptive practices with other group members, both of which are also motivated by a desire to fit in and be accepted by the group at large. These findings provide insight into how users interact with and deceive one another, but also open up room for future research into the intersection of affordances and audiences and how users modify how they present themselves in relation to those perceived components of the online experience.

Submitted in accordance with the requirements for the degree of DOCTOR OF LITERATURE AND PHILOSOPHY in the subjecr of Communication Science at the University of Zululand, 2005. / In this dissertation, I present the results of an analysis of the nature of deceptive communication. I examine when it is legitimate to deceive others and when it is not. The first part of the study renews theories and literature relevant to understanding and defining deceptive communication, human perceptions values and beliefs. I examine possible reasons why animals engage in deceptive communication. I focus on interpersonal deception; self-deception; persuasion and propaganda; nonverbal communication and people's inability to make accurate judgements of deception and ethical perspectives on deception. Subsequent chapters describe the construction of a survey instrument employed to measure and evaluate the extent of deceptive communication among university students. Penultimate chapters blend the insights gained from this literature review to interpret the results, obtained through the quantitative research methodology, to describe a set of conclusions and recommendations in the context of deceptive communication - when it is legitimate to deceive others and when it is not.

The primary aim of this research was to assess the adequacy of postexperimental inquiries (PEI) used in deception research, as well as to examine whether mood state, reward, or administering the PEI as a face-to-face interview or computer survey impacts participants' willingness to divulge suspicion or knowledge about a study. We also sought to determine why participants are not always forthcoming on the PEI. Study 1 examined how frequently PEIs are included in research and found that most researchers employing deception do use a PEI. Studies 2 and 3 showed that participants are often unwilling to divulge suspicion or awareness of deception or to admit to having prior knowledge about a study, though offering a reward and completing the PEI on a computer modestly improved awareness and admission rates. Study 4 indicated several reasons why participants may not reveal suspicion or knowledge about a study on the PEI.

“Parsing Truth in Merovingian Gaul: Evidence and the Early Medieval Critic” considers how people distinguished truth from falsehood in a set of post-Roman kingdoms occupying much of modern France and western Germany from c. 450 to 751. Using Merovingian saints’ lives, legal documents, law codes, letters, and theological and philosophical texts, I consider how people and institutions navigated the possibility that information might be presented with the intent to deceive, or might just be wrong. Responses to questions about the reliability of information ranged from the practical to the abstractly epistemological, and the period produced multiple and contradictory arguments about how knowledge could, indeed, be certain. The dissertation concludes by examining some points of contact between Merovingian critical practices and Early Modern ones, looking specifically at the management of knowledge about relics at Sens.

Online dating is becoming an increasingly used method for meeting significant others. This study had two central goals. The first goal was to explore the factors that contribute to deception used to attract a romantic partner online. The second aim was to discover the reasons that people with different attachment styles might lie as well as their justifications and interpretations for those lies. Male and female single college undergraduates (N = 208), who had previously completed an attachment style measure via an online screening, were asked to complete an online dating profile and an email to a potential dating partner. Participants reviewed these correspondences and noted any inaccuracies. They also completed a questionnaire related to lying in romantic relationships. It was hypothesized that both attachment style and gender would affect lying behavior. For online dating, results indicated that women told more self-oriented and subtle lies than men, and that high attachment avoidance and anxiety predicted greater lying behavior for participants with relationship experience. Offline, attachment predicted the motivations, justifications, and acceptability of lying to romantic partners. Implications related to online dating and attachment processes in relational deception are discussed.
