This study used Event-related Potentials (ERPs) to examine the difference between three issue types (related, foil, and unrelated issues) and two reaction types (honesty and deception reaction). This was a subject-in design. Two sets of data were collected. First, the behavior data showed that the reaction time of the deception was 200ms slower than that of honesty, and the decreasing order of ...

Deception is related to the ability to inhibit prepotent responses and to engage in mental tasks such as anticipating responses and inferring what another person knows, especially in social contexts. However, the neural correlates of deception processing, which requires mentalizing, remain unclear. Using functional magnetic resonance imaging (fMRI), we examined the neural correlates of deceptio...

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 re...

Lie or deception analysis is a significant challenge for investigators especially in crime cases. Identifying liar from normal human behaviour has higher relevance with external behaviour and cognitive functionality of human brain. Methods such as polygraph, cognitive polygraph, facial electromyography, eye tracking, voice stress analysis and functional magnetic resonance imaging have been alre...

BACKGROUND This study was aimed at: (i) examining levels of self-deception in substance dependent individuals following addiction treatment, and (ii) examining the association between participants’ levels of self-deception and (a) personality disorders, (b) addiction-related beliefs, (c) duration of abstinence, and (d) estimates of craving. METHOD We administered self-report questionnai...

With the advent of the Internet, the impact of online deception on interpersonal communication becomes intriguing. This study focuses on twenty online chatters in Taiwan with at least 2-year online chatting experience as research targets and employed qualitative interviews to solicit information about online interpersonal deception. It is found that (1) most interviewees reported that they had ...

Everyone, with the possible exception of those who are really good at it, is personally familiar with the phenomenon of self-deception. Anyone who has been conscious of struggling with a temptation to do what goes against her own better judgment and has then found justification for yielding to temptation is familiar with self-deception. So if I may be allowed to begin with the assumption that m...

The present study investigated the beliefs of students and police officers about cues to deception. A total of 95 police officers and 104 undergraduate students filled out a questionnaire addressing beliefs about cues to deception. Twenty-eight verbal cues were included in the questionnaire, all extracted from verbal credibility assessment tools (i.e., CBCA, RM, and SCAN). We investigated to wh...

We studied deceptive decision making in hypothetical scenarios that involved risk of being caught of deceiving, or a penalty after being caught of deceiving, or both. We found that the deception rate was the lowest in the scenarios involving both the risk and the penalty. Our hierarchical model for deception suggests that in balancing the possible benefits from deception, the personal discomfor...

The use of deception techniques for intelligence operations, strategic and tactical deception in war, politics, business and media manipulation is well established and well documented. This paper analyses established deception techniques in the context of the four canonical strategies of Information Warfare, to establish an information theoretical and game theoretical framework for future model...
