Pathological lying (also called pseudologia fantastica and mythomania), is a behavior of habitual or compulsive lying. It was first described in the medical literature in 1891 by Anton Delbrueck.〔 Although it is a controversial topic,〔 pathological lying has been defined as "falsification entirely disproportionate to any discernible end in view, may be extensive and very complicated, and may manifest over a period of years or even a lifetime".〔 The individual may be aware they are lying, or may believe they are telling the truth, being unaware that they are relating fantasies. ==Characteristics== Defining characteristics of pathological lying include: * The stories told are usually dazzling or fantastical, but never breach the limits of plausibility, which is key to the pathological liar's tact. The tales are not a manifestation of delusion or some broader type of psychosis; upon confrontation, the teller can admit them to be untrue, even if unwillingly. * The fabricative tendency is chronic; it is not provoked by the immediate situation or social pressure so much as it is an innate trait of the personality. There is some element of dyscontrol present. * A definitely internal, not an external, motive for the behavior can be discerned clinically: e.g., long-lasting extortion or habitual spousal battery might cause a person to lie repeatedly, without the lying being a pathological symptom.〔 * The stories told tend toward presenting the liar favorably. The liar "decorates their own person"〔 by telling stories that present them as the hero or the victim. For example, the person might be presented as being fantastically brave, as knowing or being related to many famous people, or as having great power, position, or wealth. Pathological lying may also present as false memory syndrome, where the sufferer genuinely believes that fictitious (imagined) events have taken place. The sufferer may believe that he or she has accomplished superhuman feats or awe-inspiring acts of altruism and love — or has committed equally grandiose acts of diabolical evil, for which the sufferer must atone, or indeed has already atoned in her/his fantasies. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Pathological lying」の詳細全文を読む スポンサード リンク
