OBJECTIVES: This study assesses age-related differences in the weighting and integration of appearance and behavior cues to trustworthiness. The aim is to assess whether it becomes more difficult with age to detect a cheater in disguise. METHOD: Young and older adults invested real money in a repeated trust game with trustees who varied on facial expression (smiling, neutral, angry) and return rate (high, low). Trustees were also rated for trustworthiness pre- and post-trust game...

OBJECTIVE: This study identified items on the Child Behavior Checklist (CBCL) that predict those children and adolescents with epilepsy at highest risk for multiple psychiatric diagnoses. METHODS: Three hundred twenty-eight children, ages 5-18 years, and their parents participated in separate structured psychiatric interviews about the children, which yielded Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition Text Revision (DSM-IV-TR) diagnoses...

Disorderly environments are linked to disorderly behaviors. Broken windows theory (Wilson & Kelling, 1982), an influential theory of crime and rule-breaking, assumes that scene-level social disorder cues (e.g., litter, graffiti) cause people to reason that they can get away with breaking rules. But what if part of the story is not about such complex social reasoning? Recent research suggests that basic visual disorder cues may be sufficient to encourage complex rule-breaking behavior. To test this hypothesis, we first conducted a set of experiments (Experiments 1-3) in which we identified basic visual disorder cues that generalize across visual stimuli with a variety of semantic content...

For individuals in exclusive romantic relationships, the dynamics of sexual experimentation are nuanced. Extradyadic behavior outside of a relationship may be perceived as cheating or infidelity, with much of those perceptions driven by the biological sex of the perceiver. This study significantly reframes seminal research on perceptions of cheating with third-party friends by Kruger et al. (2013), in order to further nuance an evolutionary threat-based model. In doing so, this furthers our understanding of the associated perceptions of individuals in heterosexual relationships when confronted by partners' cheating with their same-sex cross-orientation friends...

Cooperation and conflict in microorganisms is being recognized as an important factor in the organization and function of microbial communities. Many of the cooperative behaviors described in bacteria are governed through a cell-cell signaling process generally termed quorum sensing. Communication and cooperation in diverse microorganisms exhibit predictable trends that behave according to social evolutionary theory, notably that public goods dilemmas produce selective pressures for divergence in social phenotypes including cheating...

The present study was a direct test of the cheater-hawk hypothesis which argues that psychopathy is related to two potentially adaptive interpersonal strategies: cheating and aggression. As expected, the measures of cheater and hawk behaviors comprised a single factor, according to a maximum-likelihood factor analysis. As hypothesized, psychopathic traits exhibited large positive correlations with measures of both cheater (entitlement, exploitiveness, and short-term mating orientation) and hawk (vengeance and aggression) behaviors...

The present study serves to test whether the cognitive mechanisms underlying social cooperation are affected by cognitive load. Participants interacted with trustworthy-looking and untrustworthy-looking partners in a sequential Prisoner's Dilemma Game. Facial trustworthiness was manipulated to stimulate expectations about the future behavior of the partners which were either violated or confirmed by the partners' cheating or cooperation during the game. In a source memory test, participants were required to recognize the partners and to classify them as cheaters or cooperators...

AIM: To asses if the level of intention to engage others in academic transgressions was comparable among medical students from five schools from neighboring Southern-European countries: Croatia, Bosnia and Herzegovina, and Macedonia; and medical students from western EU studying at Split, Croatia. METHODS: Five medical schools were surveyed in 2011, with ≥87% of the targeted population sampled and a response rate of ≥76%. Students' intention to engage a family member, friend, colleague, or a stranger in academic transgression was measured using a previously validated the Intention to Engage Others in Academic Transgression (IEOAT) questionnaire and compared with their intention to ask others for a non-academic, material favor...

Dishonesty in academic settings is a reckless behavior that is unique to students and is associated with cheat    ing and plagiarism of academic tasks. Incidents involving dishonesty in higher education have increased considerably in the past decade, with regard to the extent of these practices, the types of dishonesty employed, and their prevalence. The current study examines the profile of "academic offenders". Which types are more prone to commit academic offenses? To what degree are they "normative" and do they represent the average student with regard to personal traits, personal perceptions, features of their academic studies, risk behaviors, and health risks...

People remember uncooperative individuals better than cooperative ones. We hypothesize that this is particularly true when uncooperative individuals belong to one's ingroup, as their behavior violates positive expectations. Two studies examined the effect of minimal group categorization on reputational memory of the social behavior of particular ingroup and outgroup members. We manipulated uncooperative behavior as the unfair sharing of resources with ingroup members (Study 1), or as descriptions of cheating (Study 2)...

: Communication has been suggested as a mechanism to stabilize cooperation. In bacteria, chemical communication termed quorum sensing (QS) has been hypothesized to fulfill this role, and extracellular public goods are often induced by QS at high cell density. Here we show with the bacterium Vibrio harveyi that QS provides strong resistance against invasion of a QS-defector strain by maximizing growth rate at low cell densities while achieving maximum productivity through protease upregulation at high cell density...

The reciprocal exchange of goods and services among social partners is a conundrum in evolutionary biology because of its proneness to cheating, but also the behavioral and cognitive mechanisms involved in such mutual cooperation are hotly debated. Extreme viewpoints range from the assumption that, at the proximate level, observed cases of "direct reciprocity" can be merely explained by basic instrumental and Pavlovian association processes, to the other extreme implying that "cultural factors" must be involved, as is often attributed to reciprocal cooperation among humans...

Ample evidence documents that power increases unethical behavior. This article introduces a new theoretical framework for understanding when power leads to more versus less unethical behavior. Our key proposition is that people hold expectations about power that are both descriptive (how the powerful do behave) and prescriptive (how the powerful should behave). People hold descriptive beliefs that the powerful do behave more unethically than the powerless, but they hold prescriptive beliefs that the powerful should behave more ethically than the powerless...

Deterministic evolutionary theory robustly predicts that populations displaying altruistic behaviors will be driven to extinction by mutant cheats that absorb common benefits but do not themselves contribute. Here we show that when demographic stochasticity is accounted for, selection can in fact act in the reverse direction to that predicted deterministically, instead favoring cooperative behaviors that appreciably increase the carrying capacity of the population. Populations that exist in larger numbers experience a selective advantage by being more stochastically robust to invasions than smaller populations, and this advantage can persist even in the presence of reproductive costs...

In the symbiosis between rhizobia and legumes, host plants can form symbiotic root nodules with multiple rhizobial strains, potentially showing different symbiotic performances in nitrogen fixation. Here, we investigated the presence of mixed nodules, containing rhizobia with different degrees of mutualisms, and evaluate their relative fitness in the Sinorhizobium meliloti-Medicago sativa model symbiosis. We used three S. meliloti strains, the mutualist strains Rm1021 and BL225C and the non-mutualist AK83. We performed competition experiments involving both in vitro and in vivo symbiotic assays with M...

Religion can have an important influence in moral decision-making, and religious reminders may deter people from unethical behavior. Previous research indicated that religious contexts may increase prosocial behavior and reduce cheating. However, the perceptual-behavioral link between religious contexts and decision-making lacks thorough scientific understanding. This study adds to the current literature by testing the effects of purely audial religious symbols (instrumental music) on moral behavior across three different sites: Mauritius, the Czech Republic, and the USA...

Fraud is a pervasive and challenging problem that costs society large amounts of money. By no means all fraud is committed by 'professional criminals': much is done by ordinary people who indulge in small-scale opportunistic deception. In this paper, we set out to investigate when people behave dishonestly, for example by committing fraud, in an online context. We conducted three studies to investigate how the rejection of one's efforts, operationalized in different ways, affected the amount of cheating and information falsification...

Social news, unlike video games or TV programs, conveys real-life interactions. Theoretically, social news in which people help or harm each other and violate rules should influence both prosocial and violation behaviors. In two experiments, we demonstrated the spreading effects of social news in a social interaction context emphasizing social conventions and a nonsocial interaction context emphasizing moral norms. Across the two studies, the results showed that positive social news increased cooperation (decreased defection) but had no effect on cheating, whereas negative social news increased cheating but with no change in cooperation (or defection)...

In a networked society like ours, reputation is an indispensable tool to guide decisions about social or economic interactions with individuals otherwise unknown. Usually, information about prospective counterparts is incomplete, often being limited to an average success rate. Uncertainty on reputation is further increased by fraud, which is increasingly becoming a cause of concern. To address these issues, we have designed an experiment based on the Prisoner's Dilemma as a model for social interactions. Participants could spend money to have their observable cooperativeness increased...

Although, lying (bear false witness) is explicitly prohibited in the Decalogue and a focus of interest in philosophy and theology, more recently the behavioral and neural mechanisms of deception are gaining increasing attention from diverse fields especially economics, psychology, and neuroscience. Despite the considerable role of heredity in explaining individual differences in deceptive behavior, few studies have investigated which specific genes contribute to the heterogeneity of lying behavior across individuals...
