One effective way for organizations to capture expert knowledge and experience is to encapsulate it within an expert system (ES) and make that system available to others. While ES users have access to the system's knowledge, they shoulder the difficult task of appropriately incorporating the ES recommendations into the decision-making process.One proposed application of an ES is in the realm of deception detection. Humans are inherently poor at recognizing deception when it occurs and their confidence in their judgments is poorly calibrated to their performance. An ES has the potential to significantly improve deception detection; however, joining an ES and a human decision maker creates many important questions that must be addressed before such a system will be useful in a field environment. These questions concern changes in decision outcomes, decision processes, and the decision maker that result from ES use.To examine these questions, a prototype system was created that implements new and unobtrusive methods of deception detection. Kinesic analysis examines the body movement of a potential deceiver and linguistic analysis reviews the structure of utterances from a potential deceiver. This prototype, complete with explanations, was utilized in two experiments that examined the effects of access to the prototype, accuracy level of the prototype, user training in deception detection, and novice or professional lie-catcher status of the users.Use of the prototype system was found to significantly improve professional and novice accuracy rates and confidence alignment. Training was found to have no effect on novice accuracy rates. Accuracy level of the prototype significantly elevated accuracy rates and confidence alignment among novices; however, this improvement was imperceptible to the novices. Novices using the prototype performed on a level equivalent to professionals using the prototype. Neither professional nor novice users of the prototype exceeded the performance of the prototype system alone. Implications of these findings include emphasizing the development of computer-based tools to detect deception and defining a new role for human users of such tools.

In this dissertation I direct critique at a conception of self-deception prevalent in analytical philosophy, where self-deception is seen as a rational form of irrationality in which the self-deceiver strategically deceives himself on the basis of having judged that this is the best thing to do or, in order to achieve something advantageous. In Chapter One, I criticize the conception of self-deception as analogous to deceiving someone else, the so-called “standard approach to self-deception”. The account under investigation is Donald Davidson’s. I criticize Davidson’s outline of self-deception as involving contradictory beliefs, and his portrayal of self-deception as a rational and strategic action. I trace the assumptions involved in Davidson’s account back to his account of radical interpretation and argue that the problems and paradoxes that Davidson discusses are not inherent in self-deception as such but are problems arising in and out of his account. In Chapter Two, I present Sebastian Gardner’s account of self-deception. Gardner is concerned with distinguishing self-deception as a form of “ordinary” irrationality that shares the structure of normal, rational thinking and action in being manipulation of beliefs from forms of irrationality treated by psychoanalysis. I object to the way in which Gardner makes this distinction and further argue that Gardner is mistaken in finding support in Freud for his claim that self-deception involves preference. In Chapter Three, I present a different understanding of self-deception. I discuss self-deception in the context of Sigmund Freud’s writings on illusion, delusion, different kinds of knowledge, etc., and propose a view of self-deception where it is not seen as a lie to oneself but rather as motivated lack of self-knowledge and as a flight from anxiety. In Chapter Four, I discuss some problems inherent in the three accounts under investigation, for example, problems arising because first-person awareness is conflated with knowledge of objects.

Deception is not only part of daily life for adults, but it is also part of typical development throughout childhood. Research has shown that the ability to deceive improves with age and has been found to be related to the development of cognitive skills such as executive functioning processes, theory of mind, and intelligence. However for some children, lie-telling becomes problematic and atypical. For children with conduct problems, deception is one of the most common presenting symptoms and has been found to be pervasive across childhood and into adolescence. While most studies analyze the lying behaviours of these children based on parent and teacher reports, no studies have yet empirically evaluated the actual deceptive behaviours of children with severe conduct problems. The current study investigated the antisocial and prosocial deception rates and abilities of children with and without severe conduct problems. Additionally, cognitive measures and parental reports of lying and parenting styles were considered in order to determine how such variables may be related to deception. A total of 66 children participated in the current study with half of the sample originating from a community agency for children with behaviour problems and the other half consisting of an age- and gender-matched control sample. Results demonstrated that compared to their typically developing counterparts, children with conduct problems were more likely to behave antisocially by committing antisocial transgressions, and subsequently lying. These children were also less likely to tell prosocial lies. Consistent with previous research, many cognitive measures, such as Executive Functioning (e.g., inhibition) and Theory of Mind (1st and 2nd Order) were found to be related to deception for the typically developing sample, though fewer and different cognitive measures were found to be predictive of deception within the clinical sample. Parent ratings of lie-telling frequency were not predictive of antisocial or prosocial deception, though they were predictive of antisocial lie-telling sophistication. Parenting styles were minimally predictive of deception. Results suggest that the mechanisms used by children with conduct problems during deception differ from a typically developing sample. Limitations as well as implications are discussed.

Were it necessary to choose two words that could capture the philosophy of Jean-Jacques Rousseau, these two words would have to be truth and nature for, in his works, this philosopher does more than assert that he, and he alone, possesses truth in its entirety. He equally maintains that his sole desire lies in sharing this truth with human kind, that we might rediscover our true nature, one that we have long ago forgotten. In fact, these very words adorn his tomb in the Pantheon where he was finally brought to rest: "Ici repose l'homme de la nature et de la verite." However, upon closer examination of two of his major works, Emile or on Education and The Social Contract, both published in 1762, a surprising contradiction is brought to light. In these treatises, he makes the child and the people believe that they are free when he is merely using rhetoric to manipulate them. For example, in Emile he gives the following advice to tutors: "Take the opposite course with your pupil; let him always think he is master while you are really master. There is no subjection so complete as that which preserves the forms of freedom; it is thus that the will itself is taken captive." While in The Social Contract he recommends using divine intervention to assure that the people "obey freely, and bear with docility the yoke of public happiness." Is Rousseau simply a gifted sophist who, by hiding the rhetoric he uses, can present himself as a man of truth in order to better form the child and the people to do his bidding? Or, is there a justification for his duplicity? Could it be possible that in some instances duplicity must be used if truth is ever to be attained by all human beings? By examining the rhetoric Rousseau uses in Emile and The Social Contract, this thesis attempts to shed some light on this somewhat troubling contradiction.

The purpose of this study was to investigate the influences of smoking on rural and urban pregnant women. More specifically, the variables of the knowledge of health effects, health provider recommendations, subscores from the Health Belief Model (HBM), and social support were explored in relation to the smoking behavior of pregnant women. A secondary purpose was to investigate the accuracy of self-reported smoking during pregnancy using biochemical validation. Pregnant women (N=71) completed an anonymous questionnaire, designed by the researcher, to identify variables that predicted smoking for urban and rural women. Participants also gave a saliva sample for cotinine testing. Approximately 47% of rural participants and 49% of urban participants were classified as smokers. The overall smoking deception rate for the current study was 5.6%. The deception rate for rural and urban participants in this study was 2.8% and 8.6%, respectively. Variables were entered into a standard multiple regression analysis to predict smoking status of the pregnant women. Participants reporting barriers (a component of the HBM) to stopping smoking during pregnancy were significantly less likely to be smokers. Through t-test and chi-square analyses, other variables related to smoking status during pregnancy included: Marital status, financial source for the pregnancy, living with husband or boyfriend, mean scores of the participants‘ knowledge of the health effects of smoking during pregnancy, susceptibility and benefits (constructs of the HBM). Many healthcare providers performed 1A, 2A, and 3A; however, few completed the last step of 4A and none completed 5A. Implications for health promotion specialists include an increase in the education of pregnant women about the health risks of maternal smoking. Additional training for pre-natal healthcare providers is necessary in order to increase the number of healthcare providers that implement all of the 5A‘s. It is important to include the husband/boyfriend in any smoking cessation interventions since they have daily influence on the smoking status of the pregnant woman. Money used to conduct biochemical verification of maternal smoking status could be better spent on patient education of the health risks of smoking during pregnancy and physician education in implementing all 5A‘s in daily practice.

Undersökningens syfte är att pröva om en mindre stat kan nyttja sig av vilseledning för att minska åverkan från en motståndare som nyttjar sig av Wardens systemteori. Undersökningen fokuserar främst på att vilseleda en motståndares målinhämtning innan ett angrepp. Undersökningen ger förslag på ett antal sätt att genomföra defensiv vilseledning, både innan ett angrepp och under påbörjat angrepp. För att underlätta för undersökningen tas fiktiva målval ut inom Sverige med stöd av Wardens litteratur och med stöd i viss annan litteratur. En mindre jämförelse mot befintliga sårbarhetsanalyser genomförs. Undersökningen har visat att alla presenterade målval utom ett har viss användning av den defensiva vilseledningen som skildras i uppsatsen. Vidare har undersökningen presenterat en motståndares troliga målval mot Sverige om motståndaren följer Wardens teori. Uppsatsen har också visat på ett antal sårbarheter i Sverige om en motståndare nyttjar Wardens teori. / The purpose of the survey is to test whether a smaller state can use deception to reduce the impact of an opponent who uses Wardens theory regarding the enemy as a system. The survey focuses on an opponent's target acquisition before an attack and the deception that might complicate the target acquisition. The survey presents a number of ways to implement defensive deception, both before and during an attack. To aid the survey a fictitious target acquisition within Sweden has been produced with the support of Wardens literature and with the support of other sources. A comparison is made between the identified vulnerabilities and existing vulnerability reports. The survey has shown that all the presented fictitious targets except one has some use of the defensive deception as presented. Furthermore the survey has presented credible targets in Sweden that an opponent might choose to attack if the opponent makes use of Wardens theory. The survey has shown several vulnerabilities in Sweden if the opponents makes use of Wardens theory.

In this thesis, Seneca&rsquo / s notion of self as self-love and the problem of self-deception are analyzed. In examining three types of self-love, &ndash / ignorant, progressing selves,&ndash / three models of self-deception are discussed. Self-deception is related to the problem of self-knowledge. I discuss the nature of self-love as self-esteem and self-preservation and self-shaping all of which are innate qualities and develop into more complex forms of knowing. Passions are concrete examples of the representations of deceived self / central to the overestimation of indifferents, the deceived self displays a pattern of reasoning that creates a paradox between what the self intends to do and what it actually appears or what the self wants to see himself as and what it actually is. In discussing various types of self-deception, it is argued that problem of deception can hardly be overcome practically even by education, although it is naturally possible. While the ignorant deceive themselves beyond their recognition, in the case of the educated selves, the tension between the knowledge of ignorance and the desire to be the person play an important role in self-deception. No one except the sage is free from self-deception. The thesis deals with the issue of self-knowing as a scarce possibility.
