Deception is a central component of the personality ''Dark Triad'' (Machiavellianism, Psychopathy and Narcissism). However, whether individuals exhibiting high scores on Dark Triad measures have a heightened deceptive ability has received little experimental attention. The present study tested whether the ability to lie effectively, and to detect lies told by others, was related to Dark Triad, Lie Acceptability, or Self-Deceptive measures of personality using an interactive group-based deception task. At a group level, lie detection accuracy was correlated with the ability to deceive others—replicating previous work. No evidence was found to suggest that Dark Triad traits confer any advantage either to deceive others, or to detect deception in others. Participants who considered lying to be more acceptable were more skilled at lying, while self-deceptive individuals were generally less credible and less confident when lying. Results are interpreted within a framework in which repeated practice results in enhanced deceptive ability. 相似文献

Can deceitful intentions be discriminated from truthful ones? Previous work consistently demonstrated that deceiving others is accompanied by nervousness/stress and cognitive load. Both are related to increased sympathetic nervous system (SNS) activity. We hypothesized that SNS activity already rises during intentions to lie and, consequently, cues to deception can be detected before stating an actual lie. In two experiments, controlling for prospective memory, we monitored SNS activity during lying, truth telling, and truth telling with the aim of lying at a later instance. Electrodermal activity (EDA) was used as an indicator of SNS. EDA was highest during lying, and compared to the truth condition, EDA was also raised during the intention to deceive. Moreover, the switch from truth telling toward lying in the intention condition evoked higher EDA than switching toward non-deception related tasks in the lie or truth condition. These results provide first empirical evidence that increased SNS activity related to deception can be monitored before a lie is stated. This implies that cues to deception are already present during the mere intention to lie. 相似文献

Lies and deception are often used in the care for demented elderly and often with the best intentions. However, there is a strong moral presumption against all forms of lying and deceiving. The goal of this article is to examine and evaluate concrete examples of deception and lies in dementia care, while addressing some fundamental issues in the process. It is argued that because dementia slowly diminishes the capacities one needs to distinguish between truths and falsehoods, the ability to be lied to also disappears. When the moral reasons to reject lying are explored, it becomes clear that most of them also hold where demented patients are concerned, though this also depends on the capacities of the patient. Lying, though prima facie wrong, can sometimes be justified with an appeal to well-being. The relationship between well-being and the truth is further explored. Two examples of deceiving demented patients for reasons of beneficence are discussed, from which it can be concluded that although in some cases beneficent lies or deception will not enhance patients' well-being, there are circumstances in which they do. In general, methods that enhance the well-being of the patient without deception or lies should be favored above options that use deceit, and methods of getting the truth across without hurting the patient should be favored above blunt honesty Finally it is important to note that not only the patient but also the nursing and medical staff can be affected by the use of lies and deception. 相似文献

The use of placebo medication, long recognized by clinicians, often has serious practical implications, such as patient deception. Past evidence has suggested that resident physicians tend to misuse placebo medication. Interns from two consecutive years of a residency program were surveyed anonymously to assess their knowledge and use of placebos. Of the 74 interns surveyed, 44 (59%) were familiar with placebo use in patient care. Fifty percent of these interns familiar with placebo use had learned about placebos from another physician. All interns who had learned about placebos during their internships had learned from another physician, whereas interns who had gained their knowledge of placebos as medical students were as likely to have learned from the medical literature as they were to have learned from a physician (P = 0.027). Interns aware of placebo use were more likely to consider placebo administration for suspected, factitious pain (P = 0.022). The present study uncovered no relationship between interns' estimations of placebo efficacy and the utility they attributed to placebos in assessing a complaint of pain. This suggests that conceptual inconsistencies underlie their use of placebos. Interns often learn of placebos as medical students and are influenced by physician-mentors. Placebo use in patient care is an area of attention for medical educators. 相似文献

The neural correlates of lying about affective information were studied using a functional magnetic resonance imaging (fMRI) methodology. Specifically, 13 healthy right-handed Chinese men were instructed to lie about the valence, positive or negative, of pictures selected from the International Affective Picture System (IAPS) while their brain activity was scanned by a 3T Philip Achieva scanner. The key finding is that the neural activity associated with deception is valence-related. Comparing to telling the truth, deception about the valence of the affectively positive pictures was associated with activity in the inferior frontal, cingulate, inferior parietal, precuneus, and middle temporal regions. Lying about the valence of the affectively negative pictures, on the other hand, was associated with activity in the orbital and medial frontal regions. While a clear valence-related effect on deception was observed, common neural regions were also recruited for the process of deception about the valence of the affective pictures. These regions included the lateral prefrontal and inferior parietal regions. Activity in these regions has been widely reported in fMRI studies on deception using affectively-neutral stimuli. The findings of this study reveal the effect of valence on the neural activity associated with deception. Furthermore, the data also help to illustrate the complexity of the neural mechanisms underlying deception. 相似文献

An organism may use misinformation, knowingly (through deception) or unknowingly (as in the case of camouflage), to gain advantage in a competitive environment. From an evolutionary perspective, greater tactical deception occurs among primates closer to humans, with larger neocortices. In humans, the onset of deceptive behaviours in childhood exhibits a developmental trajectory, which may be regarded as 'normal' in the majority and deficient among a minority with certain neurodevelopmental disorders (e.g. autism). In the human adult, deception and lying exhibit features consistent with their use of 'higher' or 'executive' brain systems. Accurate detection of deception in humans may be of particular importance in forensic practice, while an understanding of its cognitive neurobiology may have implications for models of 'theory of mind' and social cognition, and societal notions of responsibility, guilt and mitigation. In recent years, functional neuroimaging techniques (especially functional magnetic resonance imaging) have been used to study deception. Though few in number, and using very different experimental protocols, studies published in the peer-reviewed literature exhibit certain consistencies. Attempted deception is associated with activation of executive brain regions (particularly prefrontal and anterior cingulate cortices), while truthful responding has not been shown to be associated with any areas of increased activation (relative to deception). Hence, truthful responding may comprise a relative 'baseline' in human cognition and communication. The subject who lies may necessarily engage 'higher' brain centres, consistent with a purpose or intention (to deceive). While the principle of executive control during deception remains plausible, its precise anatomy awaits elucidation. 相似文献

In summary, I have argued that the arguments offered or hinted at in favour of doctors'' breaking medical confidentiality by passing on information about their patients'' HIV state to others, including other doctors, when this is against the patient''s considered wishes are generally unconvincing. Although in highly exceptional cases there may be justifications for overriding confidentiality, the requirement of medical confidentiality is a very strong, though not absolute, obligation. Patients, their contacts, doctors and their staff, and the common good are most likely to be best served if that tradition continues to be honoured. 相似文献

While there has been much research on adults' abilities to detect deception, there have been very few studies examining both children's and adults' abilities to detect children's real, spontaneous lies. The present study asked both children and adults to make judgments of children's true and false reports. Participants (N = 156) were shown videotaped sessions of children who were either spontaneously lying or telling the truth. Results indicate that both children's and adults' accuracy for detecting children's true statements was below chance. However, older children were significantly better at detecting lies than both younger children and adults. 相似文献

Current legislation indicates that physicians in Canada have a legal responsibility to know which medical conditions may impede driving ability, to detect these conditions in their patients and to discuss with their patients the implications of these conditions. The requirements to report unfit drivers vary among the provinces, and the interpretations of the law vary among the courts; therefore, physicians'' risks of liability are unclear. Physicians may be sued by their patients if they fail to counsel the patients on the dangers of driving associated with certain medications or medical conditions. Physicians may also face legal action by victims of motor vehicle accidents caused by their patients if the court decides that the physicians could have foreseen the danger of their patients'' continuing to drive. Physicians'' legal responsibilities to report patients with certain medical conditions override their ethical responsibilities to keep patients'' medical histories confidential. 相似文献

There has been a close association between Yale University and educational institutions in China for almost 80 years. Although this relationship was interrupted during the early years of the People''s Republic of China, collaboration between Yale and medical institutions in China is in the process of being resumed. The history of this collaboration and the opening phases of its resumption are described. 相似文献

To detect any change in medical students'' attitudes toward medical ethics, students from the same class were given a questionnaire on their first day of medical school and again near the end of their fourth year of study. The results showed a strong shift away from the students'' initial expectations that they would rely on specialists or scholarly sources in the future; the need for a medical ethics course in the curriculum, while still felt, was less important to them by the fourth year. The reasons for these changes were not apparent, for the students'' levels of knowledge and perceptions of the role of ethics in medicine in the first and fourth years did not differ. It is recommended that medical school faculty actively reinforce the initially positive attitudes of students during clinical supervision. 相似文献

OBJECTIVE: To assess differences between male and female medical students concerning their experiences of abuse during training in a large Canadian medical school. DESIGN: Voluntary, anonymous cross-sectional survey of first- and fourth-year medical students during February 1991. SETTING: University of Toronto School of Medicine. PARTICIPANTS: Of 396 first- and fourth-year students surveyed after one of their regular classes, 347 (117 women, 230 men) completed the questionnaire. INTERVENTION: A 165-item, multiple-choice questionnaire concerning experiences of verbal or emotional abuse, sexual harassment and physical abuse, completed within 30 minutes. MAIN OUTCOME MEASURES: Differences between male and female respondents in abuse experiences before and during medical training, the relation between abuse before and during training, and the psychologic and behavioural effects of abuse during training. RESULTS: The experiences of the male and female respondents differed mainly in regard to sexual harassment: 42% (49/117) of the women and 11% (25/230) of the men reported sexual harassment before entering medical school (p < 0.0001); 46% (54/117) and 19% (43/230) respectively reported sexual harassment during medical training (p < 0.0001); and women who reported sexual harassment were the only respondents for whom a significant relation was found between abuse before and during training (p < 0.043). The women were more distressed than the men by all forms of abuse. A significant relation was shown between male students who reported experiencing abuse during medical training and mistreating patients (p < 0.0001). CONCLUSION: Female students'' experiences of sexual harassment differed from those of their male counterparts. As well, the female students'' reactions to and ways of coping with all types of abuse differed from those of the male students. 相似文献

An Electroencephalography Network and Connectivity Analysis for Deception in Instructed Lying Tasks 总被引:1,自引:0,他引:1
Deception is an impactful social event that has been the focus of an abundance of researches over recent decades. In this paper, an electroencephalography (EEG) study is presented regarding the cognitive processes of an instructed liar/truth-teller during the time window of stimulus (question) delivery period (SDP) prior to their deceptive/truthful responses towards questions related to authentic (WE: with prior experience) and fictional experience (NE: no prior experience). To investigate deception in non-experienced events, the subjects were given stimuli in a mock interview scenario that induced them to fabricate lies. To analyze the data, frequency domain network and connectivity analysis was performed in the source space in order to provide a more systematic level understanding of deception during SDP. This study reveals several groups of neuronal generators underlying both the instructed lying (IL) and the instructed truth-telling (IT) conditions for both tasks during the SDP. Despite the similarities existed in these group components, significant differences were found in the intra- and inter-group connectivity between the IL and IT conditions in either task. Additionally, the response time was found to be positively correlated with the clustering coefficient of the inferior frontal gyrus (44R) in the WE-IL condition and positively correlated with the clustering coefficient of the precuneus (7L) and the angular gyrus (39R) in the WE-IT condition. However, the response time was found to be marginally negatively correlated with the clustering coefficient of the secondary auditory cortex (42L) in the NE-IL condition and negatively correlated with the clustering coefficient of the somatosensory association cortex (5L, R) in the NE-IT condition. Therefore, these results provide complementary and intuitive evidence for the differences between the IL and IT conditions in SDP for two types of deception tasks, thus elucidating the electrophysiological mechanisms underlying SDP of deception from regional, inter-regional, network, and inter-network scale analyses. 相似文献

The deception hypothesis has been proposed as an explanation for polygyny in the pied flycatcher. According to this hypothesis, already-mated males hide their mating status with polyterritorial behaviour and thereby increase their chances of obtaining a second mate. In a study area at Oslo, Norway, secondary females raised 84% as many fledglings as did concurrent monogamous and primary females. The unmated males sang most of the time near their nest site, whereas the already-mated males frequently disrupted singing for longer periods in their secondary territories to visit their primary nest; such visits to the primary nest occurred both before and after the time of their second mating. The behaviour of the males suggests that deception of females is not an evolutionarily stable strategy, as an observant female would soon discern the male's status. Another difficulty with the deception hypothesis is that secondary females laid larger clutches than primary females. The number of young fledged from secondary nests was not dependent on the distance to the primary nest. The deception hypothesis was not supported by the data, and the reduced reproductive success of secondary females may be explained by the cost of searching for a mate. 相似文献

The two physicians who started Canada''s first national pay-per-use medical-advice line closed the service after determining that Canadians are not willing to pay directly for their medical services. The issue of public versus private payments will likely be raised during the CMA''s annual meeting later this month. 相似文献

The doctor‐patient relationship is built on an implicit covenant of trust, yet it was not until the post‐World War Two era that respect for patient autonomy emerged as an article of mainstream medical ethics. Unlike their medical forebears, physicians today are expected to furnish patients with adequate information about diagnoses, prognoses and treatments. Against these dicta there has been ongoing debate over whether placebos pose a threat to patient autonomy. A key premise underlying medical ethics discussion is the notion that the placebo effect necessitates patient deception. Indeed, the American Medical Association guidelines imply that placebo treatment necessary entails a form of deception. As a consequence of this assumption, the fulcrum of debate on the use of placebo treatment has hinged on whether that deception is ever justified. Recently performed experiments with open‐label transparently prescribed placebos have begun to challenge the notion that deception is necessary in eliciting the placebo effect and such effects necessarily involve a binary distinction between autonomy and beneficence. In this article we focus on the content of disclosures in distinctive open‐label, transparently disclosed placebo studies and inquire whether they might be said to invoke deception in clinical contexts, and if so, whether the deception is unethical. We find that open placebos may be said to involve equivocation over how placebos work. However, drawing on surveys of patient attitudes we suggest that this equivocation appears to be acceptable to patients. We conclude that open placebos fulfil current American Medical Association guidelines for placebo use, and propose future research directions for harnessing the placebo effect ethically. 相似文献

Initiated by Associated Medical Services (AMS), Educating Future Physicians for Ontario is a 5-year collaborative project whose overall goal is to make medical education in Ontario more responsive to that province''s evolving health needs. It is supported by AMS, the five universities with medical schools or academic health sciences centres and the Ontario Ministry of Health. The project''s five objectives are to (a) define the health needs and expectations of the public as they relate to the training of physicians, (b) prepare the educators of future physicians, (c) assess medical students'' competencies, (d) support related curricular innovations and (e) develop ongoing leadership in medical education. There are several distinctive features: a focus on "demand-side" considerations in the design of curricula, collaboration within a geopolitical jurisdiction (Ontario), implementation rather than recommendation, a systematic project-evaluation plan and agreement as to defined project outcomes, in particular the development of institutional mechanisms of curriculum renewal as health needs and expectations evolve. 相似文献

Fifty years after the Nuremberg medical trial there remain many unanswered questions about the role of the German medical profession during the Third Reich. Other than the question of human experimentation, important ethical challenges arising from medicine in Nazi Germany which have continuing relevance were not addressed at Nuremberg. The underlying moral question is that of the exercise of professional power and its impact on vulnerable people seeking medical care. Sensitisation to the obligations of professional power may be achieved by an annual commemoration and lament to the memory of the victims of medical abuse which would serve as a recurring reminder of the physician''s vulnerability and fallibility. 相似文献

Both sex--the biologic aspects of being female or male--and gender--the cultural roles and meanings ascribed to each sex--are determinants of health. Medical education, research and practice have all suffered from a lack of attention to gender and a limited awareness of the effects of the sex-role stereotypes prevalent in our society. The Women''s Health Interschool Curriculum Committee of Ontario has developed criteria for assessing the gender sensitivity of medical curricula. In this article, the effects of medicine''s historical blindness to gender are explored, as are practical approaches to creating curricula whose content, language and process are gender-sensitive. Specific areas addressed include ensuring that women and men are equally represented, when appropriate, that men are not portrayed as the prototype of normal (and women as deviant), that language is inclusive and that women''s health and illness are not limited to reproductive function. By eliminating or at least addressing the subtle and often unintentional gender stereotyping in lecture material, illustrations and problems used in problem-based learning, medical educators can undertake a much-needed transformation of curriculum. 相似文献

Despite increased research during the past years, many characteristics of resting behavior in elephants are still unknown. For example, there is only limited data suggesting elephants express longer lying bouts and increased total nightly lying durations on soft substrates as compared to hard surfaces. Additionally, it has not been investigated how frequently elephants change body sides between lying bouts. Here we present these characteristics based on observations of nighttime lying behavior in 10 zoo elephants (5 African Loxodonta africana and 5 Asian Elephas maximus elephants) living in five different European facilities. We found that elephants housed on soft substrates have significantly increased total lying durations per night and longer average lying bouts. Furthermore, at 70%−85% of all bouts, a consistently higher frequency of side change between lying bouts occurred on soft substrates, leading to an overall equal laterality in resting behavior. Deviations from this pattern became evident in elephants living on nonsand flooring or/and in nondominant individuals of nonfamily groups, respectively. Based on our findings, we consider elephants to normally have several lying bouts per night with frequent side changes, given an appropriate substrate and healthy social environment. We encourage elephant-keeping facilities to monitor these characteristics in their elephants' nighttime behavior to determine opportunities for further improvements and detect alterations putatively indicating social or health problems in individual elephants at an early stage. 相似文献
