Philip Sullivan, Parmida Razavi
BACKGROUND: The coaching process is complex and dynamic. Coaches are known to affect athlete attitudes indirectly, through athletes' perceptions and interpretations. This process has been verified with a variety of ethical behaviors. OBJECTIVES: The current study investigated the relationships between athletes' perceived doping confrontation efficacy of their coaches and athlete's anti-doping attitudes. METHODS: A sample of athletes (N = 96) completed a version of the Doping Confrontation Efficacy Scale that was modified to assess their perception of their coaches' anti-doping confrontation efficacy, and the PEAS (Performance Enhancing Attitude Scale), which assessed their performance-enhancing attitudes...

Simon Gingins, Dominique G Roche, Redouan Bshary
Predatory reef fishes regularly visit mutualistic cleaner fish (Labroides dimidiatus) to get their ectoparasites removed but show no interest in eating them. The concept of compensated trait loss posits that characters can be lost if a mutualistic relationship reduces the need for a given trait. Thus, selective pressures on escape performance might have relaxed in L. dimidiatus due to its privileged relationship with predators. However, the cost of failing to escape a predatory strike is extreme even if predation events on cleaners are exceptionally rare...

We studied the emotional processes that allow people to balance two competing desires: benefitting from dishonesty and keeping a positive self-image. We recorded physiological arousal (skin conductance and heart rate) during a computer card game in which participants could cheat and fail to report a certain card when presented on the screen to avoid losing their money. We found that higher skin conductance corresponded to lower cheating rates. Importantly, emotional intelligence regulated this effect; participants with high emotional intelligence were less affected by their physiological reactions than those with low emotional intelligence...

Bacteria produce a wide variety of exoproducts that favourably modify their environment and increase their fitness. These are often termed 'public goods' because they are costly for individuals to produce and can be exploited by non-producers (cheats). The outcome of conflict over public goods is dependent upon the prevailing environment and the phenotype of the individuals in competition. Many bacterial species use quorum sensing (QS) signalling molecules to regulate the production of public goods. QS, therefore, determines the cooperative phenotype of individuals, and influences conflict over public goods...

Honesty plays a key role in social and economic interactions and is crucial for societal functioning. However, breaches of honesty are pervasive and cause significant societal and economic problems that can affect entire nations. Despite its importance, remarkably little is known about the neurobiological mechanisms supporting honest behavior. We demonstrate that honesty can be increased in humans with transcranial direct current stimulation (tDCS) over the right dorsolateral prefrontal cortex. Participants (n = 145) completed a die-rolling task where they could misreport their outcomes to increase their earnings, thereby pitting honest behavior against personal financial gain...

Biological studies of the evolution of cooperation are challenging because this process is vulnerable to cheating. Many mechanisms, including kin discrimination, spatial structure, or by-products of self-interested behaviors, can explain this evolution. Here we propose that the evolution of cooperation can be induced by other cooperation. To test this idea, we used a model organism Dictyostelium discoideum because it exhibits two cooperative dormant phases, the fruiting body and the macrocyst. In both phases, the same chemoattractant, cyclic AMP (cAMP), is used to collect cells...

Adam Fine, Benjamin van Rooij
Deterrence threats are essential mechanisms for affecting behavior, yet they are often ineffective. The literature is beginning to consider individual differences underlying differential susceptibility to deterrence. The present study sampled 223 adults from Amazon Mechanical Turk and used an experimental cheating paradigm to examine the role of 3 individual differences, including morality, self-control, and rule orientation, underlying differential susceptibility to deterrence. The results indicate that deterrence threats may be more influential for people who have low moral disengagement, who possess more self-control, or who are more rule oriented...

Wen-Hsiung Wu, Wen Cheng, Wen-Bin Chiou
Delay discounting refers to a pervasive tendency toward preferring smaller immediate gains over larger future gains. Recent empirical research has shown that episodic future thinking (EFT; i.e., projecting oneself into the future to pre-experience forthcoming events) can reduce the tendency toward discounting. A common tenet of psychological theories of crime is that delinquency results from focusing on short-term gains while failing to consider adequately the longer-term consequences of delinquent behavior...

Many species engage in mutualistic relationships with other species. The physiological mechanisms that affect the course of such social interactions are little understood. In the cleaning mutualism, cleaner fish Labroides dimidiatus do not always act cooperatively by eating ectoparasites, but sometimes cheat by taking bites of mucus from so-called "client" reef fish. The physiological mechanisms in these interspecific interactions, however, are little studied. Here, we focussed on three neuromodulator systems known to play important roles in intraspecific social behaviour of vertebrates to examine their role in clients' interspecific behaviour...

R Fredrik Inglis, Erica Ryu, Odion Asikhia, Joan E Strassmann, David C Queller
The evolution of multicellularity is one of the key transitions in evolution and requires extreme levels of cooperation between cells. However, even when cells are genetically identical, non-cooperative cheating mutants can arise that cause a breakdown in cooperation. How then, do multicellular organisms maintain cooperation between cells? A number of mechanisms that increase relatedness amongst cooperative cells have been implicated in the maintenance of cooperative multicellularity including single cell bottlenecks and kin recognition...

Sarah Trainer, Alexandra Brewis, Amber Wutich
Cultural notions equating greater morality and virtue with hard work and productive output are deeply embedded in American value systems. This is exemplified in how people understand and execute personal body projects, including efforts to become slim. Bariatric surgery is commonly viewed as a 'low-effort' means of losing weight, and individuals who opt for this surgery are often perceived to be 'cheating.' This extended ethnographic study within one bariatric program in the Southwestern United States shows how patients conscientiously perform this productivity...

Emissions of NOX by vehicles in real driving environments are only partially understood. This has been brought to the attention of the world with recent revelations of the cheating of the type approval tests exposed in the dieselgate scandal. Remote sensing devices offer investigators an opportunity to directly measure in-situ real driving emissions of tens of thousands of vehicles. The availability of remote sensing NO2 measurements are not as widely available as would be desirable. The aim of this study is to improve the ability of investigators to estimate the NO2 emissions and to improve the confidence of the total NOX results calculated from standard RSD measurements...

Most approaches to dishonest behavior emphasize the importance of corresponding payoffs, typically implying that dishonesty might increase with increasing incentives. However, prior evidence does not appear to confirm this intuition. However, extant findings are based on relatively small payoffs, the potential effects of which are solely analyzed across participants. In two experiments, we used different multi-trial die-rolling paradigms designed to investigate dishonesty at the individual level (i.e., within participants) and as a function of the payoffs at stake - implementing substantial incentives exceeding 100€...

REVIEW
Nick J Davis
Advances in neuroscience and pharmacology have led to improvements in the cognitive performance of people with neurological disease and other forms of cognitive decline. These same methods may also afford cognitive enhancement in people of otherwise normal cognitive abilities. "Cosmetic", or supranormal, cognitive enhancement offers opportunities to enrich our social or financial status, our interactions with others, and the common wealth of our community. It is common to focus on the potential benefits of cognitive enhancement, while being less than clear about the possible drawbacks...

Although all 3 of the Dark Triad members are predisposed to engage in exploitative interpersonal behavior, their motivations and tactics vary. Here we explore their distinctive dynamics with 5 behavioral studies of dishonesty (total N = 1,750). All 3 traits predicted cheating on a coin-flipping task when there was little risk of being caught (Study 1). Only psychopathy predicted cheating when punishment was a serious risk (Study 2). Machiavellian individuals also cheated under high risk-but only if they were ego-depleted (Study 3)...

Tracy E Douglas, David C Queller, Joan E Strassmann
Unequal investment by different sexes in their progeny is common and includes differential investment in the zygote and differential care of the young. The social amoeba Dictyostelium discoideum has a sexual stage in which isogamous cells of any two of the three mating types fuse to form a zygote which then attracts hundreds of other cells to the macrocyst. The latter cells are cannibalized and so make no genetic contribution to reproduction. Previous literature suggests that this sacrifice may be induced in cells of one mating type by cells of another, resulting in a higher than expected production of macrocysts when the inducing type is rare and a giving a reproductive advantage to this social cheat...

BACKGROUND: Advocacy for male involvement in family planning has been championed over the years after the 1994 International Conference on Population and Development (ICPD). There are a few contraceptive methods for men, and vasectomy uptake has been identified as one of the indicators of male involvement in family planning. Vasectomy also known as male sterilization is a permanent form of contraception. It is a generally safe, quick, easy, effective surgical operation with rare complications to prevent release of sperm...
