In this paper we focused on children’s deception (10-12 years, Experiment 1), and adult’s ability detect deception in children (Experiment 2). The self-presentational perspective (DePaulo, 1992) suggests that both liars and truth tellers will try to act in a convincing manner to be assessed as truth tellers. By asking unanticipated questions we put the liars in the following dilemma: If they di...

Aim: We examined the ability to detect lying about opinions with Devil’s Advocate Approach and Verifiability Approach. Method: Interviewees were first asked an opinion eliciting question argue in favour of their alleged personal view. This was followed by a devil’s advocate against Since reasons that support rather than oppose are more readily available people’s minds, we expected truth tellers...

A $2k computer can execute about 8k transactions per second. This is 80x more than one of the largest US bank’s 1970’s traffic – it approximates the total US 1970’s financial transaction volume. Very modest modern computers can easily solve yesterday’s problems. 1. A Thousand-Transactions-per-second was once difficult and expensive. In 1973, Bank of America wanted to convert their paper-based b...

Telling lies often requires creating a story about an experience or attitude that does not exist. As a result, false stories may be qualitatively different from true stories. The current project investigated the features of linguistic style that distinguish between true and false stories. In an analysis of five independent samples, a computer-based text analysis program correctly classified lia...

This report describes two simple extensions to the paper A Robust and Veri able Cryptographically Secure Election Scheme presented in the 1985 Symposium on the Foundations of Computer Science. The rst extension allows the \government" to be divided into an arbitrary number of \tellers". With this extension, trust in any one teller is su cient to assure privacy, even if the remaining tellers con...

Practitioners ask whether verbal veracity cues are (i) diagnostic across populations and resistant to countermeasures. We examined this by merging the three datasets reported Vrij, Leal et al. (2020, 2022).Participants from Lebanon (n = 187), Mexico 205) South-Korea 239) discussed a city-trip they had made (truth tellers, n 328) or up story (lie 303) about such trip. Some participants 325) were...

Timed automata is an abstraction that can provide a way of expressing timing delays when the behavior of a real time system is modeled. Then, for the verification of specifications and properties of the system model checking techniques can be used. In this work an attempt is made to model an on-line transaction processing system with timed automata. We describe a bank that has multiple branches...

Deception has evolved to become a fundamental aspect of human interaction. Despite the prolonged efforts in many disciplines, there has been no definite finding of a univocally "deceptive" signal. This work proposes an approach to deception detection combining cognitive load manipulation and T-pattern methodology with the objective of: (a) testing the efficacy of dual task-procedure in enhancin...

According to Vrij, the differences between liars and truth tellers are greater when interviewees report their stories in reverse order than in chronological order. We intend to explore such influences on the organization of behavior within the framework of the T-pattern model. This model grants the possibility to measure and compare behavior patterns between liars and truth tellers, not easily ...

We tested the hypothesis derived from eye blink literature that when liars experience cognitive demand, their lies would be associated with a decrease in eye blinks, directly followed by an increase in eye blinks when the demand has ceased after the lie is told. A total of 13 liars and 13 truth tellers lied or told the truth in a target period; liars and truth tellers both told the truth in two...
