Much robotics research explores how robots can clearly communicate true information. Here, we focus on the counterpart: communicating false information, or hiding information altogether – in one word, deception. Robot deception is useful in conveying intentionality, and in making games against the robot more engaging. We study robot deception in goal-directed motion, in which the robot is conce...

We report results from a sender-receiver cheap talk game, which explores whether an individual’s decision to deceive is influenced by a concern for relative standing in a reference group. We show theoretically that positively biased senders, who think they are higher in the deception distribution than they actually are, will correct their beliefs and increase their cheating, when presented with...

To explain how people judge that others are lying, an expectancy-violation model is proposed. According to the model, deception is perceived from nonverbal behavior that violates normative expectation. To test the model, 3 experiments were conducted, 2 in the United States and 1 in India. In each experiment, people described acquaintances while exhibiting weird nonverbal behaviors, such as arm ...

BACKGROUND Deception detection has been a longstanding concern throughout human history. It has also interested scientists, who have explored psychological and behavioral differences between liars and truth tellers, as well as ways to improve detection accuracy. METHOD In recent years, substantial advances have been made in the field. Some of these advances are briefly reviewed in the current...

Individuals often work together in environments where computers mediate their communication. One key area affected by computer mediated communication in group settings is the transmission of cues to deception. If cues to deception are filtered, such as they are with computer-mediated communication, deception detection accuracy can be hindered due to the lack of cues available, and group task pe...

We present a system for covert automated deception detection using information available in a video. We study the importance of different modalities like vision, audio and text for this task. On the vision side, our system uses classifiers trained on low level video features which predict human microexpressions. We show that predictions of high-level microexpressions can be used as features for...

This study examined whether priming with social deception affects responses (pain estimates, self-reported sympathy, inclination to help) towards others' pain. We further explored whether the priming effect is mediated by the valence of the patients (positive/negative), as indicated by the participants. First, participants (N=55) took part in an 'independent' delayed memory study in which they ...

Pollination by sexual deception is arguably one of the most unusual liaisons linking plants and insects, and perhaps the most illustrative example of extreme floral specialization in angiosperms. While considerable progress has been made in understanding the floral traits involved in sexual deception, less is known about how this remarkable mimicry system might have arisen, the role of pre-adap...

How does self-deception affect the appreciation of humor and laughter? Fifty-nine undergraduates at Rutgers University (33 females, 26 males) were videotaped while watching a stand-up comedian for 28 min. Positive emotional expressions associated with laughter were analyzed for short sections of the act (total: 8 min or 14,400 video frames) and were scored for each subject using the facial acti...

Scripture uses several Greek and Hebrew words to denote deception, particularly in relation to the future period of Tribulation. Second Thess 2:11 is of special interest in discussions of deception during that future time, because God is the agent who sends the “deluding influence” (energeian plan‘s) among unbelievers. Two OT passages which present God as in some way deceiving are analogous to ...
