Attention deficit/hyperactivity disorder (ADHD) has been linked to higher engagement in sexual risk-taking behavior (SRTB). The current study aims to establish the link between ADHD symptoms and SRTB in the general population and to examine whether an exaggerated perceived benefit of the positive outcomes of SRTB explains that link. A scale for measuring the frequency, likelihood, perceived benefit, and perceived risk of SRTB was developed. Young adult sexually active participants who did not have a stable partnership completed the above scale, (...) as well as a scale of ADHD symptoms. Level of ADHD symptoms positively correlated with the frequency and likelihood of SRTB, even when the overall level of sexual behavior was controlled for. ADHD symptoms also correlated with the perceived benefit of SRTB, but not with the perceived risk of SRTB. Mediation analysis confirmed an indirect pathway: ADHD symptoms predicted perceived benefit of SRTB, which in turn predicted increased likelihood to engage in SRTB. These findings suggest a positive link between ADHD symptoms and SRTB in the general population, which is accounted for by an exaggerated perceived benefit of SRTB. (shrink)

Risk-taking behavior is particularly widespread during adolescence, and negatively impacts the healthy growth and social adaptation of adolescents. Utilizing problem-behavior theory and the family stress model, the current study examined the relationship between socioeconomic status and adolescents’ risk-taking behavior, as well as the mediating role of psychological capital and self-control. A total of 1,156 Chinese adolescent students completed a series of questionnaires anonymously. The results showed that: Socioeconomic status was negatively correlated with adolescents’ risk-taking behavior; Both psychological capital and (...) self-control mediated the relationship between SES and adolescents’ risk-taking behavior independently; and Psychological capital and self-control also mediated the relationship between SES and the risk-taking behavior of adolescents sequentially. This study reveals the internal mechanism of risk-taking behavior during adolescence and provides theoretical support and empirical evidence for preventing and reducing such behavior in this age group.

Most research on risk aversion in behavioral science with human subjects has focused on a component of risk aversion that does not adapt itself to context. More recently, studies have explored risk aversion adaptation to changing circumstances in sequential decision-making tasks. It is an open question whether one can identify evidence, at the single subject level, for such risk aversion adaptation. We conducted a behavioral experiment on human subjects, using a sequential decision making task. We developed a model-based approach (...) for estimating the adaptation of risk-taking behavior with single-trial resolution by modelling a subject’s goals and internal representation of task contingencies. Using this model-based approach, we estimated the subject-specific adaptation of risk aversion depending on the current task context. We found striking inter-subject variations in the adaptation of risk-taking behavior. We show that these differences can be explained by differences in subjects’ internal representations of task contingencies and goals. We discuss that the proposed approach can be adapted to a wide range of experimental paradigms and be used to analyze behavioral measures other than risk aversion. (shrink)

This research examined whether youth's forecasted risk taking is best predicted by a compensatory (namely, subjective expected utility) or non-compensatory (e.g., single-factor) model. Ninety youth assessed the importance of perceived benefits, importance of perceived drawbacks, subjective probability of benefits, and subjective probability of drawbacks for 16 risky behaviors clustered evenly into recreational and health/safety domains. In both domains, there was strong support for a noncompensatory model in which only the perceived importance of the benefits of engaging in a (...) risky behavior predicted youths' forecasted engagement in risky behavior. The study overcomes earlier methodological weaknesses by fully decomposing participants' assessments into importance and probability aspects for both benefits and drawbacks. As such, the findings provide clear evidence in support of a boundedrationality perspective on youth decision making regarding risk taking. (shrink)

This chapter presents a model of risk‐taking behaviour. That is, it describes some simpler patterns of preference than real people ever have, and then discusses some strategies that would make sense for people with these simple preferences when faced with choices between risky options. These strategies can also make sense for people, with the more complicated preferences. The chapter also discusses some more detailed assumptions about snobs' preferences. There are several ways in which the Snobs can find (...) their way through risky situations. The chapter considers two. The first is, in effect, to refuse to reason probabilistically. Given every risky prospect they can decide what the most likely outcome is, equate it to a certainty of that outcome, and choose accordingly. In more complex situations something closer to real probabilistic reasoning will be needed. And this is the second way in which preferences such as those of the snobs can come to terms with risk.

Investigating the bases of inter-individual differences in risk-taking is necessary to refine our cognitive and neural models of decision-making and to ultimately counter risky behaviours in real-life policy settings. However, recent evidence suggests that behavioural tasks fare poorly compared to standard questionnaires to measure individual differences in risk-taking. Crucially, using model-based measures of risk taking does not seem to improve reliability. Here we put forward two possible - not mutually exclusive - explanations for these results and suggest future avenues (...) of research to improve the assessment of inter-individual differences in risk-taking by combining repeated online testing and mechanistic computational models.

Models of risk-taking as used in the social sciences may be improved by including concepts from life history theory, particularly environmental unpredictability and life expectancy. Community college students completed self-report questionnaires measuring these constructs along with several well-known correlates. The frequency of risk-taking was higher for those with higher future unpredictability beliefs and shorter lifespan estimates (as measured by the Future Lifespan Assessment developed for this study), and unpredictability beliefs remained significant after accounting for standard predictors, such as sex and (...) temperament. The results demonstrate the usefulness of applying concepts from life history theory to enhance our understanding of human behavior. (shrink)

The present study assessed the degree to which probabilistic reasoning performance and thinking style influenced perception of risk and self-reported levels of terrorism-related behaviour change. A sample of 263 respondents, recruited via convenience sampling, completed a series of measures comprising probabilistic reasoning tasks (perception of randomness, base rate, probability, and conjunction fallacy), the Reality Testing subscale of the Inventory of Personality Organization (IPO-RT), the Domain-Specific Risk-Taking Scale, and a terrorism-related behaviour change scale. Structural equation modelling examined three progressive (...) models. Firstly, the Independence Model assumed that probabilistic reasoning, perception of risk and reality testing independently predicted terrorism-related behaviour change. Secondly, the Mediation Model supposed that probabilistic reasoning and reality testing correlated, and indirectly predicted terrorism-related behaviour change through perception of risk. Lastly, the Dual-Influence Model proposed that probabilistic reasoning indirectly predicted terrorism-related behaviour change via perception of risk, independent of reality testing. Results indicated that performance on probabilistic reasoning tasks most strongly predicted perception of risk, and preference for an intuitive thinking style (measured by the IPO-RT) best explained terrorism-related behaviour change. The combination of perception of risk with probabilistic reasoning ability in the Dual-Influence Model enhanced the predictive power of the analytical-rational route, with conjunction fallacy having a significant indirect effect on terrorism-related behaviour change via perception of risk. The Dual-Influence Model possessed superior fit and reported similar predictive relations between intuitive-experiential and analytical-rational routes and terrorism-related behaviour change. The discussion critically examines these findings in relation to dual-processing frameworks. This includes considering the limitations of current operationalisations and recommendations for future research that align outcomes and subsequent work more closely to specific dual-process models.

We examine the implications of the US government’s too-big-to-fail policy as it has been applied to banks. Using alternative measures of risk, we compare the risk-taking behavior of 11 TBTF banks, identified by the Comptroller of the Currency in 1984, to a number of non-TBTF banks. We provide both theory and new empirical evidence to support our argument that the TBTF policy leads management to significantly increase risk-taking, with no corresponding increase in performance. While prior studies have considered the effects (...) of the TBTF policy on limited, but risk-related aspects of bank behavior, such as the cost of funds, our study provides direct evidence about the risk-taking behavior associated with the TBTF policy. Our study has important implications for the current political debate regarding the too-big-to-fail policy. (shrink)

The attempts to mitigate the unprecedented health, economic, and social disruptions caused by the COVID-19 pandemic are largely dependent on establishing compliance to behavioral guidelines and rules that reduce the risk of infection. Here, by conducting an online survey that tested participants’ knowledge about the disease and measured demographic, attitudinal, and cognitive variables, we identify predictors of self-reported social distancing and hygiene behavior. To investigate the cognitive processes underlying health-prevention behavior in the pandemic, we co-opted the dual-process model of (...) thinking to measure participants’ propensities for automatic and intuitive thinking vs. controlled and reflective thinking. Self-reports of 17 precautionary behaviors, including regular hand washing, social distancing, and wearing a face mask, served as a dependent measure. The results of hierarchical regressions showed that age, risk-taking propensity, and concern about the pandemic predicted adoption of precautionary behavior. Variance in cognitive processes also predicted precautionary behavior: participants with higher scores for controlled thinking (measured with the Cognitive Reflection Test) reported less adherence to specific guidelines, as did respondents with a poor understanding of the infection and transmission mechanism of the COVID-19 virus. The predictive power of this model was comparable to an approach (Theory of Planned Behavior) based on attitudes to health behavior. Given these results, we propose the inclusion of measures of cognitive reflection and mental model variables in predictive models of compliance, and future studies of precautionary behavior to establish how cognitive variables are linked with people’s information processing and social norms.

Risk-taking behaviours often reflect ambivalent ways of calling for the help of one’s close friends and family – those who count. It is an ultimate means of finding meaning and a system of values; and it is a sign of the adolescent’s active resistance and his attempts to find his place in the world again. It contrasts with the far more insidious risk of depression and the radical collapse of meaning. In spite of the suffering it engenders, risk-taking nevertheless has (...) a positive side, fostering independence in adolescents and a search for reference points, it leads to a better self-image and is a means of developing one’s identity. It is nonetheless painful in terms of its possible repercussions: injuries, death or addiction. But let us not forget that the suffering is upstream, perpetuated by a complex relation between a society, a family structure and a life history. Paradoxically, for some young people who are suffering, the risk is rather that they will remain immured in their world-weariness, with a potentially radical outcome (i.e. suicide). The turbulence caused by risk-taking behaviours illustrates a determination to be rid of one’s suffering and to fight on so that life can, at last, be lived. (shrink)

This paper studies the effects of social comparison on risk taking behavior. In our theoretical framework, decision makers evaluate the consequences of their choices relative to both their own and their peers’ conditions. We test experimentally whether the position in the social ranking affects risk attitudes. Subjects interact in a simulated workplace environment where they perform a work task, receive possibly different wages, and then undertake a risky decision that may produce an extra gain. We find that social comparison matters (...) for risk attitudes. Subjects are more risk averse in the presence of small social gain than social loss. In addition, risk aversion is decreasing in the size of the social gain. (shrink)

An issue that affects the academic engagement, performance, health and wellbeing of university undergraduates is bullying. Substantial literature has examined the predictors of bullying perpetration, but there is little research on the contributions of internet-related factors and the propensity to take risks in bullying. We examined the roles of IGD, risk-taking behavior, and internet addiction in social bullying. Four instruments were used for data collection, namely: Young Adult Social Behavior Scale, the Internet Gaming Disorder Scale, Domain-Specific Risk-Taking Scale, and the (...) Internet Addiction Test Scale. Participants were 552 undergraduate students from the University of Nigeria, Nsukka consisting of 143 males and 409 females. Results of regression analysis showed that gaming disorder and risk-taking behavior had positive associations with social bullying. Thus, the more people grow addicted to internet gaming and takes more risks, the more they are likely to become bullies. Internet addiction had no significant association with social bullying. Efforts should be made to minimize the rate of dysfunctional internet use, GD and risk-taking behaviors of undergraduates in order to curtail bullying perpetration. (shrink)

Mood and optimism have been demonstrated to influence risk-taking decisions; however, the literature on mood, optimism, and decision-making is mixed and conducted primarily with western samples. This study sought to address this gap in the literature by examining the impact of mood and dispositional optimism on risk-taking and whether these associations differed between undergraduate students from the United States and the People’s Republic of China. Both samples completed a dispositional optimism questionnaire and an autobiographical mood induction task. They were then (...) tasked with choosing to complete the Raven’s Advanced Progressive Matrices reasoning task on easy, medium, or hard difficulty for hypothetical money. Selecting harder difficulties was interpreted as more risk-taking due to a higher chance of failure. More positive mood and higher dispositional optimism were associated with decreased risk-taking, i.e., selecting easier puzzle difficulties, in the American sample but increased risk-taking decisions, i.e., selecting harder difficulties, in the Chinese sample. These findings suggest that the effect of mood and optimism on decision-making may differ by nationality and/or culture. (shrink)

The study seeks to determine the influence of economic reward on unethical behavior with the help of a Reward Punishment Model. The model postulates that ethical or unethical behavior depends on the relationship among three factors: economic reward or benefit that a businessperson receives from the unethical practice, the severity of punishment the society imposes for such wrong-doing, and the probability of receiving the punishment. A short survey, which contained a hypothetical ethical situation, was administered to 251 respondents. (...) The findings indicate that the probability of risk-taking decreases as the level of punishmentand the chance of being caught increases. (shrink)

This article analyzes the conditions under which any change in a multiplicative background risk induces a more cautious behavior. We give necessary and sufficient conditions under which any change in the multiplicative background risk with respect to the Nth-degree stochastic dominance raises local risk aversion. Surprisingly, decreasing relative risk aversion of any order up to N in the sense of Pratt coupled with decreasing relative risk aversion in the sense of Ross are sufficient to guarantee an increase in local risk (...) aversion after any deterioration of the multiplicative background risk thanks to the Nth-degree stochastic dominance. We link our results concerning second-order stochastic dominance with the concept of multiplicative risk vulnerability. (shrink)

This paper examines the mechanisms that influence team-level performance, which is critical to organizational effectiveness. It investigates psychological safety, a shared belief that the team is safe for interpersonal risk-taking, and a causal model mediated by learning behavior and efficacy. This model hypothesizes that psychological safety and efficacy are related, which have been believed to be the same-dimension constructs. It also explains the process of how learning behavior affects the team’s efficacy. According to a study of 104 field (...) teams in a multinational enterprise in Korea, psychological safety did not affect team effectiveness. However, when mediated by learning behavior and efficacy, a full mediation effect was found. The result supports a well-known metaphor that psychological safety is the engine of performance, not the fuel. It also explains how individuals contribute to group performance under a psychologically safe climate, enhancing team processes. Based on the findings, this paper suggests theoretical and methodological implications for future research to maximize the effectiveness of teams. (shrink)

This study explores the impact of cooperative engagement with nonfamily employees, consumers, and communities on risk-taking behavior of privately held, long-lived family firms. We posit that cooperative relations can build and reinforce connectedness among the family and nonfamily stakeholders which, in turn, can lead to increased risk-taking. More specifically, the increased stability from widespread cooperative nonfamily engagement will positively moderate risk-taking behavior by amplifying the influence of family involvement in privately held family firms. Using a unique survey of long-lived, privately (...) held family firms, we find support for our hypotheses: cooperative engagement interacts with the essence of family involvement to amplify risk-taking. This study contributes to the stakeholder engagement and family firm literatures and offers managerial and policy implications by underscoring the benefits of cooperative engagement as it enhances risk-taking of family firms, a precursor of growth.

This paper will explore some of the implications of attending to the performative aspects of language for the sociological understanding of issues of risk and trust among lay communities. Ulrich Beck and Anthony Giddens have alerted us to the way that in late or reflexive modernity trust in authority cannot be taken for granted, but increasingly has to be actively earned and actively invested. For his part, Brian Wynne has pointed out that lay judgements are relational and hermeneutic, including as (...) they do judgements about the behaviour of relevant expert institutions, and about the risk to one's self-identity incurred by being caught up in relationships of dependency. Wynne has also argued that public avowals of trust can often mask deep private distrust, and thus be expressions more of fatalistic acceptance than of genuine trust. However, all of these analyses work from a basic model of ' trust ' as being the result of a cognitive process – as a judgement as to the trustworthiness of others. Yet trust is frequently 'active' in an even stronger sense than this. To take a posture of trust towards another can often be best understood not just as a cognitive judgement but as an attempt to bind the 'trusted' into a relationship and attitude of responsibility – and thus perhaps to alter their behaviour – through the taking up of a position in a social ritual. Speech act theory can help us be sensitive to this sort of use of the language of ' trust ', by reminding us that language can perform a number of different functions – not just that of describing the world, or of acting out ascribed roles and identities, but also that of trying to change the world. The analysis of public discourse about risk, trust and mistrust must thus be sensitive to the range of things that people might be attempting to do when they are saying things if it is to avoid drawing misleading conclusions about public attitudes to risk.

Recent developmental models assume a higher tendency to take risks in mid-adolescence, while the empirical evidence for this assumption is rather mixed. Most of the studies applied quite different tasks to measure risk-taking behavior and used a narrow age range. The main goal of the present study was to examine risk-taking behavior in four task settings, the Treasure Hunting Task (THT) in a gain and a loss domain, the Balloon Analogue Risk Task (BART) and the STOPLIGHT task. These task settings (...) differ in affective task moderators, like descriptive vs. experienced outcomes, anticipation of gains vs. losses, static vs. dynamic risk presentation and time pressure vs. no-time pressure and were applied in a sample of 187 participants from age 9 to 18. Beneath age trends, we were interested in their association with individual differences in approach behavior, venturesomeness, impulsivity and empathy above age, gender and fluid intelligence. Our findings revealed that risk-taking behavior is only low to moderately correlated between the four task contexts, suggesting that they capture different aspects of risk-taking behavior. Accordingly, a mid-adolescent peak in risk-propensity was only found under time pressure in the STOPLIGHT that was associated with higher impulsivity and empathy. In contrast, risky decisions decreased with increasing age in task settings, in which losses were anticipated (THT Loss), and this was associated with higher cognitive abilities. We found no age differences when gains were anticipated, neither in a static (THT Gain) nor in a dynamic task setting (BART). These findings clearly suggest the need to consider affective task moderators, as well as individual differences in temperament and cognitive abilities, in actual models about adolescent development.

School psychologists often break confidentiality if confronted with risky adolescent behavior. Members of the National Association of School Psychologists ( N = 78) responded to a survey containing a vignette describing an adolescent engaging in risky behaviors and rated the degree to which it is ethical to break confidentiality for behaviors of varying frequency, intensity, and duration. Respondents generally found it ethical to break confidentiality when risky adolescent behaviors became more dangerous or potentially harmful, although there was considerable variability between (...) respondents. Significant gender effects were found between male and female respondents for alcohol use, and a significant Form Type (i.e., male or female vignette) Frequency/Duration interaction was observed for antisocial behaviors. School psychologists could benefit from further training in ethical decision making because these ethical dilemmas are not always clear-cut. (shrink)

The unsafe behavior of construction workers is one of the most important and direct causes of safety accidents. Managers usually develop effective incentives aimed at regulating worker safety behavior. Due to the large number of workers in construction projects, there are multiple differences in fairness preference, risk preference and ability level, which will lead to the complex effect of the traditional mechanism to regulate workers’ safety behavior. In order to improve the effectiveness of incentive measures for worker safety behavior, this (...) paper takes into account the multiple differences of individual workers’ fairness preference, risk preference and ability level, based on the tournament mechanism to construct a competition incentive model. By designing a tournament reward and salary distribution for heterogeneous workers, the occurrence of unsafe behaviors can be reduced. The study found that in terms of the optimal level of safety investment, workers with risk aversion attitude generally invest higher than that of workers with risk preference, no matter whether they have a strong fairness preference or not; In terms of the distribution of tournament rewards, workers with a risk aversion attitude and a higher level of fairness preference need to be given higher incentives.

This poster presents results from applying agent-based modeling to an exploration of risk attitudes and rational decision making in the context of group interaction. We are also interested in the place of agent-based modeling and computational philosophy within the computational humanities. Computational philosophy has not typically been included in Digital Humanities; computational work has been done using philosophy texts as a source for analysis (Kinney 2022; Malaterre et al. 2021; Fletcher et al. 2021; Zahorec et al. 2022), but there are (...) few examples of philosophical arguments being made based on computation (Zahorec et al. 2022). Modeling is largely accepted as a computational humanist method (McCarty 2004; So 2022), but typically models are based on data rather than designed simulations as a method analogous to a thought experiment (Mayo-Wilson / Zollman 2021). Agent-based modeling is not as common in computational humanities, but we are interested in its potential; for instance, see work modeling correspondence networks to better understand lost information and biases in correspondence data sets (Buarque / Vogl 2023), or work simulating past human societies (Romanowska et al. 2021). Our project explores Lara Buchak’s theory of risk-weighted rational decision making by extending it to the context of group populations and interactions. Buchak has proposed risk-weighted expected utility maximization, which incorporates individual risk attitudes into the standard expected utility (EU) calculation based on utility and probability of outcomes (Buchak 2017). This theory provides an explanation for differences of behavior seen in human populations, while still allowing those different choices to be rational. Buchak’s theory has previously only been applied to individual decision making; our work uses agent-based modeling to develop and analyze simulations which incorporate a variety of risk attitudes (risk avoidance and risk seeking) into game theoretic interactions. This project is a collaboration between a philosopher and a research software engineer; we have worked together to develop simulations that implement agents with risk attitudes making risky choices. This presentation focuses on results from an implementation of a hawk/dove game with multiple risk attitudes and risk attitude adjustment. In the hawk/dove game cooperation, or playing dove, is better for the population, but acting aggressively, or playing hawk, is better for an individual if they are in a neighborhood of doves. To set up the game, we place agents on a grid and have them play against each of their neighbors, and accumulate payoffs based on the success of their plays. We define risk attitudes 0 through 9, where that number corresponds to the minimum number of neighbors playing dove for an agent to play hawk. An agent with risk attitude 0 is most risk seeking and always plays hawk; an agent with risk attitude 1 will play hawk if at least one neighbor plays dove; an agent with risk attitude 9 always takes the safe choice and plays dove; an agent with risk attitude 4 or 5 is risk neutral (breaking ties in different ways), which corresponds to expected utility. In this simulation we randomly set agent initial risk attitudes, and then every ten rounds agents compare their payoffs with their neighbors and adopt the most successful risk attitude in their neighborhood. The simulation is coded to stop once risk attitude adjustments stabilize. We define 13 different population states based on primary and second majority of risk averse, risk inclined, or risk moderate, and analysis of over 1 million runs indicate that while it’s more likely to stabilize with the population having become majority risk inclined, that is not the only outcome; we also see cases where the population stabilizes as risk neutral, risk avoidant, and many cases with no clear majority. This diversity of stable populations provides support for the argument that no one risk attitude is uniquely rational, but rather that risk attitudes are conventional. This matches what we observe in the real world: that different populations have different risk attitudes. Our simulations include numerous parameters to vary grid size; adjustment frequency, strategy, and wealth comparison; neighborhood sizes for observing previous choice, playing against, and comparing payoffs for adjusting risk attitudes; and different distributions for initializing risk attitudes. Analysis of parameters and adjusted risk attitudes shows that the strongest correlations are the initial distribution of risk attitudes, which tend to be preserved. * * * This poster was accepted and presented at the DH2024 conference in Washington, D.C.

There are several strategies to promote health in individuals and populations. Two general approaches to health promotion are behavior change and empowerment. The aim of this article is to present those two kinds of strategies, and show that the behavior-change approach has some moral problems, problems that the empowerment approach (on the whole) is better at handling. Two distinct ‘ideal types’ of these practices are presented and scrutinized. Behavior change interventions use various kinds of theories to target people’s behavior, which (...) they do through information, persuasion, coercion and manipulation. Empowerment is a collaborative method where those ‘facilitated’ participate in the change process. Some ethical problems with the behavior-change model are that it does not sufficiently respect the right to autonomy of the individuals involved and risks reducing their ability for autonomy, and that it risks increasing health inequalities. Empowerment, on the other hand, respects the participant’s right to autonomy, tends to increase the ability for autonomy, as well as increasing other coping skills, and is likely to reduce inequalities. A drawback with this approach is that it often takes longer to realize. (shrink)

Much research has explored the physiological, energetic, environmental, and psychological factors that influence pacing in endurance events. Although this research has generally neglected the role of psychological variation across individuals, recent studies have hinted at its importance. Here we conducted an online survey of over 1,300 marathon runners, testing whether any of five psychological constructs—competitiveness, goal achievement, risk taking in pace (RTP), domain-specific risk taking, and willingness to suffer in the marathon—predicted slowing in runners’ most recent marathons. Analyses revealed that (...) RTP—the extent to which runners agreed that they began the marathon at a pace that was so fast that it would jeopardize their capacity to maintain this pace throughout the event—was a robust predictor of marathon slowing. RTP proved a substantial predictor even in regression models controlling for the other psychological constructs, training, experience, and other known pacing correlates. This result suggests that marathoners consider trade-offs when making pacing decisions, and that individuals vary in their pacing decision making. (shrink)

Reporting peers’ counterproductive work behaviors (CWBs) is important for maintaining an ethical organization, but is a significant and potentially risky action. In Bandura’s Theory of Moral Thought and Action (Bandura, 1991) he states that such acts require significant moral agency, which is generated when an individual possesses adequate moral self-regulatory capacities to address the issue and is in a context that activates and reinforces those capacities. Guided by this theory, we assess moral potency (i.e., moral courage, moral efficacy, and moral (...) ownership) as key capacities predicting peer reporting intentions and assess three contextual factors influencing the generation and effects of moral potency: whether a potential informant (1) works for an ethical leader, (2) is embedded in a psychologically safe climate promoting interpersonal risk-taking, and (3) operates in a more normal or extreme context. We assess the proposed model across three field studies entailing both normal and extreme (i.e., firefighting units) contexts. Results show that ethical leaders raise employees’ moral potency, promoting greater willingness to report their peers’ CWBs. In normal work contexts, psychological safety positively moderated both the relationship between ethical leadership and moral potency and between moral potency and peer reporting intentions. However, psychological safety had the opposite effects in more extreme work contexts. Whereas psychological safety strengthens the positive association between moral potency and peer reporting intentions in normal work contexts, in contexts where individuals are more frequently exposed to extreme events, psychological safety weakens this relationship, thus highlighting the unforeseen downsides of psychological safety in extreme contexts.

The study of the autonomic nervous system (ANS) function has shown to provide useful indicators for risk stratification and early detection on a variety of cardiovascular pathologies. However, data gathered during different tests of the ANS are difficult to analyse, mainly due to the complex mechanisms involved in the autonomic regulation of the cardiovascular system (CVS). Although model-based analysis of ANS data has been already proposed as a way to cope with this complexity, only a few models coupling the (...) main elements involved have been presented in the literature. In this paper, a new model of the CVS, representing the ventricles, the circulatory system and the regulation of the CVS activity by the ANS, is presented. The models of the vascular system and the ventricular activity have been developed using the Bond Graph formalism, as it proposes a unified representation for all energetic domains, facilitating the integration of mechanic and hydraulic phenomena. In order to take into account the electro-mechanical behaviour of both ventricles, an electrophysiologic model of the cardiac action potential, represented by a set of ordinary differential equations, has been integrated. The short-term ANS regulation of heart rate, cardiac contractility and peripheral vasoconstriction is represented by means of continuous transfer functions. These models, represented in different continuous formalisms, are coupled by using a multi-formalism simulation library. Results are presented for two different autonomic tests, namely the Tilt Test and the Valsalva Manoeuvre, by comparing real and simulated signals. (shrink)

Research suggests that people with psychopathic traits experience fear-inducing stimuli differently from others, seeming to interpret fear as more positive and less negative. We expected that this reaction, termed fear enjoyment, would impact the effect of fear-inducing stimuli on self-report risk-taking behaviour. Risk-taking was measured before and after viewing excitement- and fear-inducing videos (N = 825). As expected from research showing that fear induction tends to reduce risk-taking tendencies, participants showed reduced risk-taking scores following a fear-inducing stimulus. Importantly, this (...) relationship was moderated by psychopathic traits. Participants who did not decrease their risk-taking tendencies following the video scored significantly higher on psychopathic traits. Also, some of the variance in the relationship between psychopathic traits and change in risk-taking was partly accounted for by fear enjoyment, suggesting that future research should examine whether fear enjoyment may play a role in the relationship between psychopathy and risk-taking.

There continues to be significant confusion about the goals, scope, and nature of modelling practice in neuroeconomics. This article aims to dispel some such confusion by using one of the most recent critiques of neuroeconomic modelling as a foil. The article argues for two claims. First, currently, for at least some economic model of choice behaviour, the benefits derivable from neurally informing an economic model do not involve special tractability costs. Second, modelling in neuroeconomics is best understood (...) within Marr’s three-level of analysis framework and in light of a co-evolutionary research ideology. The first claim is established by elucidating the relationship between the tractability of a model, its descriptive accuracy, and its number of variables. The second claim relies on an explanation of what it can take to neurally inform an economic model of choice behaviour. 1 Introduction2 Neurally Informed Models of Choice: A Case Study2.1 A case study on risk-sensitive choice2.1.1 Target and modelling framework2.1.2 Research question and hypotheses2.1.3 Competitive models of risk-sensitive behaviour2.1.4 Model-based fMRI: from economics to brains and back2.2 Neurally informed modelling3 Tractability: When Does Size Matter?4 Neural Integration and the Co-evolutionary Research Ideology5 Conclusion.

La théorie de la décision a inspiré des modèles du risque qui formalisent des choix de comportement dont la diversité tient à des facteurs individuels, sociaux et environnementaux. Comme le droit routier cherche à modifier les comportements, ces modèles ont inspiré des politiques publiques et des réformes juridiques ou judiciaires. Leurs effets sont limités par la diversité des déterminants des comportements et l’éclatement des groupes qui prennent des risques. Ces modèles n’en restent pas moins un guide pertinent pour l’action générale (...) de l’État, surtout si des actions spéciales la complètent. Celles-ci pourraient porter sur des cibles spécifiques avec des démarches appropriées, appuyées par l’éducation et la prévention.The decision-making theory has inspired risk models which formalize behaviour choices. Their diversity is due to individual, social and environmental factors. Since road safety laws aim at changing behaviours, these models have inspired policies as well as legal or judicial reforms. Their effects are limited by the variety of decision factors and the dispersal of risk-taking groups. Yet these models do remain a relevant guide for overall state action, particularly if it is enhanced by special actions. The latter could be aimed at special targets using adequate strategies backed by education and prevention. (shrink)

We present a theoretical model of health beliefs and behaviors that explicitly takes into account the emotional impact of possible bad news, ex-ante in the form of anxiety and ex-post in the form of disappointment. Our model makes it possible to explain a number of anomalies such as ’low’ testing rates, heterogeneous perceptions of risk levels, underestimation of health risk, ostriches and hypochondriacs, over-use and under-use of health services, patient preference for information when relatively certain of not being (...) ill, yet avoiding information when relatively certain of being ill, etc. Our model matches observed patterns both in health beliefs and health behaviors and irrational health beliefs and behaviors can be characterized as the optimal response under a given structure of emotions and preferences.

Are risk-takers more likely to engage in unethical behaviors? We examined the relationship between risk-taking propensity and cheating in two experimental studies. In Study 1, we examined the relationship between subjects’ risk-taking propensity and their actual self-serving dishonesty using a gambling-like task. The results suggested that risk-taking propensity, measured using a behavioral approach, was positively correlated with actual self-serving dishonest behavior. In Study 2, we measured participants’ performances using a matrices test and found that the positive correlation still held. We (...) found that participants with high risk-taking propensity reported a lower perceived probability of being detected, which might drive their dishonest behavior. (shrink)

At present, there are almost 700 million rural population in China, and the farm and farmers in China are highly associated with the steadiness and development of the country and even the world. Farmers are the main subjects in rural development and play a vital role in the reception, management, and benefit distribution in rural tourism activities during the development of rural tourism. Farmers’ perception and participation intention in rural tourism development are directly related to the sustainable development of rural (...) tourism and the realization of rural revitalization goals. The decision-making process of participation in the rural tourism development fits the application conditions of the technology acceptance model. Therefore, in order to explore the influencing factors of farmers’ decision-making process in participating in the rural tourism, this study employs the technology acceptance model to predict and judge individual farmers’ willingness and behavior to participate in the rural tourism. The government trust and perceived risk in the real problem of low participation of farmers in the rural tourism development are considered. Then, an extended technology acceptance model was established by taking 409 farm households as research samples. The influence of government trust on farmers’ participation intention in the rural tourism was empirically analyzed based on the PLS-SEM model. The results show that farmers’ perceived usefulness and perceived ease of use in rural tourism affect their participation intention. Farmers’ judgments on whether governments can assume public responsibilities and achieve public interests through rural tourism development affects their trust in government, while the government trust can positively affect farmers’ participation intention via perceived usefulness and perceived ease of use. This indicates that government trust is an important antecedent variable influencing farmers’ participation in the rural tourism. The perceived risk affects farmers’ perceived usefulness and participation intention in the rural tourism, and plays a moderating role in the relationship between government trust and perceived usefulness. Finally, this study recommends to highlight the utility and convenience of rural tourism participation during the promotion of farmers’ participation in rural tourism development, enhance the ability of farmers to participate in rural tourism development, and choose multiple channels to increase government trust to reduce farmers’ risk concerns.
