Email, chat, instant messaging, blogs, and newsgroups are now common ways for people to interact. Along with these new ways for sending, receiving, and storing messages comes the challenge of organizing, filtering, and understanding them, for which text mining has been shown to be useful. Additionally, it has done so using both content-dependent and content-independent methods.Unfortunately, computer-mediated communication has also provided criminals, terrorists, spies, and other threats to security a means of efficient communication. However, the often textual encoding of these communications may also provide for the possibility of detecting and tracking those who are deceptive. Two methods for organizing, filtering, understanding, and detecting deception in text-based computer-mediated communication are presented.First, message feature mining uses message features or cues in CMC messages combined with machine learning techniques to classify messages according to the sender's intent. The method utilizes common classification methods coupled with linguistic analysis of messages for extraction of a number of content-independent input features. A study using message feature mining to classify deceptive and non-deceptive email messages attained classification accuracy between 60\% and 80\%.Second, speech act profiling is a method for evaluating and visualizing synchronous CMC by creating profiles of conversations and their participants using speech act theory and probabilistic classification methods. Transcripts from a large corpus of speech act annotated conversations are used to train language models and a modified hidden Markov model (HMM) to obtain probable speech acts for sentences, which are aggregated for each conversation participant creating a set of speech act profiles. Three studies for validating the profiles are detailed as well as two studies showing speech act profiling's ability to uncover uncertainty related to deception.The methods introduced here are two content-independent methods that represent a possible new direction in text analysis. Both have possible applications outside the context of deception. In addition to aiding deception detection, these methods may also be applicable in information retrieval, technical support training, GSS facilitation support, transportation security, and information assurance.

Nusikaltimo ir civilinės teisės pažeidimo atribojimo problema nepraranda savo aktualumo. Jį ypač išryškėja bandant atrasti civilinės teisės pažeidimo ir sukčiavimo atribojimo kriterijus. Šio magistro baigiamojo darbo tikslas - nustatyti baudžiamosios ir civilinės teisės santykį, visapusiškai išnagrinėti sukčiavimą kaip teisinį reiškinį, atskleisti jo sudėties požymius, raidą, pasireiškimo formas bei atrasti atribojimo nuo civilinės teisės pažeidimų kriterijus. Darbe analizuojama teisės normų taikymo praktika, jos trūkumai, pateikiami pasiūlymai, siekiant įstatymo taikymo tobulinimo. Darbe iškelta hipotezė, kad trys pagrindiniai sukčiavimo atribojimo nuo civilinės teisės pažeidimo kriterijai yra apgaulė, kreditoriaus galimybės apginti savo teises civilinės teisės priemonėmis atėmimas ar apsunkinimas panaudojant apgaulę bei tiesioginę tyčią. / The problem of the delimitation between criminal and civil delict is still relevant. Especially it appears significant when attempting to find the delimitation criterions for the fraud and the civil delict. The aim of this Master’s thesis is to find the relation between the criminal and civil law, to analyze a fraud in all its legal aspects, to detect the elements constituting this criminal offence, its evolution and realization forms and to justify delimitation criterions between it and civil delict. Court practice in fraud field and its drawbacks are considered; also suggestions for development of law practice are given in this Master’s thesis. Hypothesis of this Master’s thesis is proposition, that there are three principal delimitation criterions between fraud and civil delict: deception, deprivation of access for creditor to maintain his (her) rights by means of civil law or imposition on these rights by means of deception and the deliberate tortuous intent.

Three studies were undertaken to examine the relationship between the Dark Triad (i.e., psychopathy, Machiavellianism, and narcissism) and faking ability. Study 1 examined the relationship between psychopathy and the ability to fake good and fake bad on self-report personality inventories in a sample of 84 male federal offenders. Results showed that when faking good, successful fakers scored significantly higher than unsuccessful fakers on carefree nonplanfulness, and significantly lower on stress immunity. When faking bad, successful and unsuccessful fakers did not differ significantly on psychopathy total or subscale scores. Study 2 examined the effect of the Dark Triad on the ability to fake good and fake bad on self-report personality inventories in a sample of 166 undergraduates. Results indicated that when faking good, total psychopathy significantly predicted successful faking for 1 of 3 methods of evaluation, while Machiavellianism significantly predicted success at faking good for 2 of 3 methods of evaluation. Narcissism was unrelated to success at faking good. In addition, the Dark Triad constructs did not predict success at faking bad. Study 3 examined the relationship between the Dark Triad constructs and the ability to fake good interpersonally. In this study, 32 undergraduates comprising four groups (i.e., controls, and individuals high in psychopathy, Machiavellianism, and narcissism) provided videotaped self-presentations. A separate group of 134 university students subsequently rated the veracity of these presentations. Results indicated that when faking good, psychopathy and narcissism groups were rated as more believable than the control group. Conversely, the Machiavellianism group was less successful at faking good than the control group. Contributions of this research to the fields of personality assessment and self-presentation are discussed. / Thesis (Ph.D, Psychology) -- Queen's University, 2008-10-14 11:24:45.946

Traditionally, Macbeth has been read as a morality tale about the perils of ambition. The question that has implicitly animated most treatments of the play is, "Why does Macbeth kill Duncan?" By shifting the emphasis away from Macbeth's motives for killing Duncan onto his inability to refrain from killing him, I draw attention to the striking fact that, in killing King Duncan, Macbeth acts against a fully considered better judgment not to. This suggests the possibility that Macbeth's much-discussed ambition can be understood as a subset of the broader theme of akrasia , the condition in which an agent is unable to perform an action he knows to be right. After identifying and exploring the theme of akrasia in several of Shakespeare's plays, I go on to situate Macbeth's murder of Duncan in the context of the long literary and philosophical debate on incontinence. I then suggest four interrelated explanations of Macbeth's akrasia. First, Macbeth's connection to the motivational conditions of his knowledge is shallow; he does not feel what he knows. Second, Macbeth's lack of self-control is habitual because his weak connection to the conative dimension of his knowledge prohibits him from appealing to techniques of skilled resistance. Third, his habitual lack of self-control renders him vulnerable to Lady Macbeth's taunts, which not only deplete the motivation supporting his better judgment but also prevent him from giving full deliberative weight to his better judgment. Finally, Macbeth also engages in a consistent pattern of self-deception that not only facilitates his akratic slaughter of King Duncan but also enables him to murder Banquo and MacDuff's family. My explanation of how Macbeth is able to act self-deceptively against his better evidence echoes my account of how he is able to act akratically against his better judgment: he does not feel what he knows.

With the judicial system worldwide investigating finance companies for misleading disclosures, deception has become a topical issue. However, deception is an area that has historically not been favoured in academia. The paper aims to determine whether disclosure practices of failed companies show more characteristics of deception than those of viable companies. The research will involve a mixture of qualitative and quantitative methodologies, including the use of content analysis and the software DICTION. An index of deception is constructed. The higher the deception score, the more deceptive the authors are deemed to be. This study tests this argument with respect to the prospectuses of a sample of failed and non-failed New Zealand finance companies.

The construct of repression has received a resurgence of experimental attention in the past 20 years, due in large part to the development of the typology method of classification (Weinberger, Schwartz, and Davidson, 1979). According to the typology method, individuals are classified as repressors if they self-report low anxiety and high social desirability. Since the typology method of classification does not differentiate between the two factors comprising social desirability (impression management and self-deception), it is important to determine which component is actually characterizing repressors, or whether it is a combination of the two. The present study examined two questions; (1) are repressors engaging in self-deception, impression management, or both and (2) does the construct of repression change as a function of age? Results suggest that in a college age population self-deception characterized the repressor memory; in an elderly population present negative mood state was the only variable predicting repressive memory. / Department of Psychological Science

In our pilot study investigating Texas Hold ‘em poker, we found that players bluffing (with a losing hand) elicits a similar physiological arousal response (as measured by skin conductance levels) to those in a position of strength and poised to win. Since arousal has been suggested to be a reinforcing factor in problematic gambling behaviour, we sought to replicate the findings of our pilot study in the current investigation. We aimed to extend our previous findings further by: isolating truthful betting (strong betting) to disambiguate deception when players are in positions of strength (i.e. trapping), measuring subjective excitement levels and risk assessments, investigating the physiological arousal responses following wins versus losses, and finally, exploring group differences (i.e. problem gambling status, experience levels). 71 participants played 20 naturalistic rounds of Texas Hold ‘em poker for monetary rewards. We were able to replicate our previous findings that bluffing triggers a physiological arousal (as measured by skin conductance responses) similar to truthful strong betting. Trapping was also found to elicit a skin conductance response similar to both bluffing and strong betting. Measures of subjective excitement revealed a pattern that converged with physiological data. Furthermore, wins were found to be more arousing than losses. Finally, our exploratory analysis of group differences (i.e. problem gambling status, experience) proved to be an insignificant factor with all measures. We conclude that the effect of bluffing on physiological arousal is so powerful that it pervades all participants; which is problematic due to its risky nature and potential to be self-triggered. With its ever increasing popularity and availability, more research on Texas Hold ‘em poker is warranted for treatment implications.
