Assessing Deception Differences with Mimicry Deception Theory

Mimicry Deception Theory (MDT) argues that deception varies along a long- to short-term continuum. Long-term deception involves complex deception, community integration, slow resource extraction, and low detectability, whereas short-term deception is the opposite. To date, no self-report scale exists that assesses a dispositional orientation toward long-term deception. Across four studies, we developed and validated a Mimicry Deception Scale (MDS) to assess individuals' dispositional orientation toward long-term deception. Using theoretically driven items, we found a reliable four-factor structure through exploratory and confirmatory factor analyses. Further, MDS components were strongly correlated and had acceptable internal consistency. For convergent validity, long-term MDS positively correlated with Machiavellianism, conscientiousness, and planning. Finally, the test-retest reliability of the MDS was acceptable, and the complexity facet of the MDS predicted successful lying over time. The findings have implications for how to profile, identify, and recognize patterns of deception, especially with respect to long-term patterns using self-report.

Lie prevalence, lie characteristics and strategies of self-reported good liars

Meta-analytic findings indicate that the success of unmasking a deceptive interaction relies more on the performance of the liar than on that of the lie detector. Despite this finding, the lie characteristics and strategies of deception that enable good liars to evade detection are largely unknown. We conducted a survey (n = 194) to explore the association between laypeople’s self-reported ability to deceive on the one hand, and their lie prevalence, characteristics, and deception strategies in daily life on the other. Higher self-reported ratings of deception ability were positively correlated with self-reports of telling more lies per day, telling inconsequential lies, lying to colleagues and friends, and communicating lies via face-to-face interactions. We also observed that self-reported good liars highly relied on verbal strategies of deception and they most commonly reported to i) embed their lies into truthful information, ii) keep the statement clear and simple, and iii) provide a plausible account. This study provides a starting point for future research exploring the meta-cognitions and patterns of skilled liars who may be most likely to evade detection.

Brain activation and adaptation of deception processing during dyadic face-to-face interaction

Though deception is consistently characterized by the slippery-slope effect, i.e., the escalation of small lies over time, differing interactive situations and interacting processes may influence the trajectories of deception. To explore this influence, we investigated naturalistic face-to-face (FF) and computer-mediated face-blocked (FB) interactions using functional near-infrared spectroscopy (fNIRS). Pairs of participants acted as deceivers and receivers in an adapted ultimatum game while brain activity in the right dorsolateral prefrontal cortex (rDLPFC) and temporoparietal junction (rTPJ) was recorded. Comparison of deception in the two types of interactions showed that the FF interactions resulted in more successful deception, as well as acceptance of deception, and prompted more neural activation in the rDLPFC than the FB interactions. We found that the deception magnitude escalated in both FF and FB interactions, but rDLPFC activity during deception diminished over time only in the FF interactions but not in FB interactions, suggesting that the deceivers behaviourally adapted to deception over time in both types of interactions, but the neural adaptation occurred only in the FF interactions. Furthermore, neural adaptation in FF interactions was associated with behavioural switching after deception, indicating that the rDLPFC contributes to deception adaptation and the control of switching between deception and honesty. The FF interactions were also characterized by activity in the rTPJ, which showed an adaptation to deception. These findings highlight the importance of interactive situations in dyadic naturalistic settings for deception and the role of the rDLPFC and rTPJ in the slippery-slope effect in deception.

Communication, compassion, and computers: Adolescents' and adults' evaluations of online and face-to-face deception

We explored Canadian adolescents', emergent adults', and adults' understandings of deception in computer mediated communication (CMC) compared to face to face (FtF). Participants between 13 and 50 years read vignettes of different types of questionable behaviour that occurred online or in real life, and were asked to judge whether deception was involved, and the acceptability of the behaviour. Age groups evaluated deception similarly; however, adolescents held slightly different views from adults about what constitutes deception, suggesting that the understanding of deception continues to develop into adulthood. Furthermore, CMC behaviour was rated as more deceptive than FtF in general, and participants scoring higher on compassion perceived vignettes to be more deceptive. This study is a step towards better understanding the relationships between perceptions of deception across adolescence into adulthood, mode of communication, and compassion, and may have implications for how adults communicate with youth about deception in CMC and FtF contexts.

Trading with privacy: the price of personal information

Purpose

– The purpose of this paper is to examine how users in an anonymous virtual environment react to an offer to trade in access to their social network profile.

Design/methodology/approach

– The experiment was conducted in Second Life (SL). Participants were offered varied sums of money in exchange for access to their Facebook profile, effectively undermining their anonymity.

Findings

– Even in an anonymous environment, money plays a role in users’ decisions to disclose their offline identity, but a closer look at the findings reveals that users also use deception to enjoy the benefits of the offer without paying the costs. The results illustrate three types of users according to the strategies they employ: abstainers, traders, and deceivers.

Research limitations/implications

– The implications to the field of online information disclosure lie at the ability to illustrate and distinguish between the different strategies users choose with regard to online information disclosure, as the study design simulates a common information disclosure trade offer in online environments.

Originality/value

– Unlike previous studies that focussed on trades with specific pieces of information, this study examines willingness to sell access to a user’s entire profile, by thus better simulating online services conduct. This is also the first privacy experiment conducted in the anonymous environment of SL, and the first to study deception as a privacy protection strategy.

Self-reported gambling problems and digital traces

The Diagnostic and Statistical Manual of Mental Disorder, Fifth Edition (DSM-5), lists concealment as one of the symptoms of a gambling disorder. However, some transactions are more likely to leave permanent records of gambling transactions (credit, consumer loyalty schemes) than others (cash, Internet cash, Internet cafes, prepaid phones). An online survey of 815 participants recruited through newspaper and online sites elicited consumer preferences for a variety of transactions and communication media. Hierarchical multiple regression accounted for age, gender, housing status, and involvement in gambling before considering relationships between consumer preferences and scores on the Problem Gambling Severity Index. Even after statistically allowing for the contributions of other variables, a greater risk of developing a gambling problem was associated with a preference for cash transactions, prepaid mobile phones, and Internet cafes. Problem gamblers may seek to reduce their digital trace.

An evidence-based approach to an ancient pursuit: systematic review on converting online contact into a first date

OBJECTIVE

To determine, for people seeking a date online, what activities and behaviours have an effect on the chances of converting electronic communication into a face-to-face meeting.

METHODS

Literature in psychology, sociology, and computer, behavioural and neurocognitive sciences that informed effective online dating was captured through electronic searching of Psychinfo, Medline and Embase in November 2013. Study selection and meta-narrative synthesis were carried out in duplicate.

RESULTS

There were 3938 initial citations and 86 studies were synthesised. Initial interest was best captured through: a desirable screen name starting with a letter in the top half of the alphabet; an attractive still picture; and a fluent headline message. For those attracted to browse into the profile, a description of personal traits increased likeability when it: showed who the dater was and what they were looking for in a 70:30 ratio; stayed close to reality; and employed simple language with humour added. Invitations were most successful in obtaining a response from the potential date when they: were short personalised messages addressing a trait in their profile; rhymed with their screen name or headline message; and extended genuine compliments. Online communication was most effective in leading to an in-person meeting if there were: a genuine interest; a rapid turnaround; reciprocity in self-disclosure; mimicry of body movements on the webcam; avoidance of criticism; humour; uncertainty about whether there was likeability; and an early move from electronic chat to a date.

CONCLUSIONS

Attraction and persuasion research provides an evidence-based approach to online dating.
