This paper describes how basic concepts from information theory can be used to analyze deception. We show how a general definition of deception can be mapped to a simple communication model known as a Z-channel, and we show that any deception has associated with it a closely related deception we call it’s symmetric complement. These ideas allow computation of a specific form of conditional entr...

UNLABELLED This study examined the impact of evidence concerning the presence of 1) a biomedical basis for pain and 2) psychosocial influences on practitioner appraisals of patient pain experiences. Furthermore, the potential moderating role of patient pain behavior was examined. In an online study, 52 general practitioners and 46 physiotherapists viewed video sequences of 4 patients manifestin...

The paper proposes to use Rhetorical Structure Theory (RST) analytic framework to identify systematic differences between deceptive and truthful stories in terms of their coherence and structure. A sample of 36 elicited personal stories, self-ranked as completely truthful or completely deceptive, is manually analyzed by assigning RST discourse relations among a story’s constituent parts. Vector...

Deception has been demonstrated as a task that involves executive control such as conflict monitoring and response inhibition. In the present study, we investigated whether or not the controlled processes associated with deception could be trained to be more efficient. Forty-eight participants finished a reaction time-based differentiation of deception paradigm (DDP) task using self- and other-...

The orchid family is renowned for its enormous diversity of pollination mechanisms and unusually high occurrence of non-rewarding flowers compared to other plant families. The mechanisms of deception in orchids include generalized food deception, food-deceptive floral mimicry, brood-site imitation, shelter imitation, pseudoantagonism, rendezvous attraction and sexual deception. Generalized food...

the attempt to find out if someone is telling a lie has been of human's interest. one of the techniques which is believed to be efficient in future is fmri (functional magnetic resonance imaging), using which the changes of regional blood flow during the designed paradigm can be recorded. this method has been considered as a better technique for studying lie and deception. for investigatin...
