Incentives have surprisingly inconsistent effects when it comes to encouraging people to behave prosocially. Classical economic theory, according to which a specific behavior becomes more prevalent when it is rewarded, struggles to explain why incentives sometimes backfire. More recent theories therefore posit a reputational cost offsetting the benefits of receiving an incentive -- yet unexplained effects of incentives remain, for instance across incentive types and countries. We propose that social norms can offer an explanation for these inconsistencies. Ultimately, social norms determine the reputational costs or benefits resulting from a given behavior, and thus variation in the effect of incentives may reflect variation in norms. We implemented a formal model of prosocial behavior integrating social norms, which we empirically tested on the real-world prosocial behavior of blood donation. Blood donation is essential for many life-saving medical procedures, but also presents an ideal testing ground for our theory: Various incentive policies for blood donors exist across countries, enabling a comparative approach. Our preregistered analyses reveal that social norms can indeed account for the varying effects of financial and time incentives on individual-level blood donation behavior across 28 European countries. Incentives are associated with higher levels of prosociality when norms regarding the incentive are more positive. The results indicate that social norms play an important role in explaining the relationship between incentives and prosocial behavior. More generally, our approach highlights the potential of integrating theory from across the economic and behavioral sciences to generate novel insights, with tangible consequences for policy-making., 34 pages, 11 figures

ObjectiveProsocial behavior has been linked to improved physical health, but the biological mechanisms involved remain unclear. This study tested whether a 4-week kindness intervention could reduce expression of a stress-related immune response gene signature known as the Conserved Transcriptional Response to Adversity (CTRA).MethodsIn a diverse sample of community adults (N=182), study participants were randomly assigned to perform 3 kind acts for other people, to perform 3 kind acts for themselves, or to list daily activities (control), on one day per week over 4weeks. CTRA gene expression was measured by RNA sequencing of dried blood spots (DBS) collected at baseline and 5weeks later (1week after completing study assignments). Participants' descriptions of their kind acts were coded for protocol adherence and act content.ResultsParticipants who were randomized to perform kind acts for others showed significant reductions in CTRA gene expression relative to controls. Participants who were randomized to perform kind acts for themselves also showed significant reductions in CTRA gene expression relative to controls, but this pattern emerged only for those who failed to perform the requested self-kind acts (protocol non-adherent). Those who fully adhered to the self-kindness protocol showed no change in CTRA gene expression and did not differ from controls. Act content analyses implicated self-stress-reducing behavior in the paradoxical effects of self-kindness and the physical presence of others in the effects of prosocial behavior.ConclusionsProsocial engagement-doing something kind for others rather than oneself-reduces CTRA gene expression. The nature of kind acts and their intended recipient plays a key role in shaping the genomic impact of kindness.

This study investigates how customer requests, a common phenomenon, influence frontline employee (FLE) job outcomes. We propose and demonstrate that (1) FLEs possess tendencies to appraise customer requests in both positive (i.e., challenge appraisal tendency) and negative (i.e., hindrance appraisal tendency) ways, (2) higher levels of challenge appraisal tendency result in higher levels of FLE performance and lower levels of turnover (mediated through job engagement), (3) higher levels of hindrance appraisal tendency lead to increased FLE turnover (mediated through job stress), (4) the effects of FLE appraisal tendencies on situational engagement and stress are magnified when a specific customer request is deemed to be more (rather than less) demanding, and (5) customer request appraisal tendencies are shaped by the interaction between FLEs’ level of prosocial motivation and intrinsic motivation. These results are very encouraging for managers as they imply that FLE responses to customer requests are not determined by the nature of the requests themselves (which is beyond their control) but, rather, they are a function of how FLEs construe customer requests, a process that can be influenced through organizational human resource practices.

The goal of this study was to elucidate the fundamental connectivity-resting-state connectivity-within and between nodes in the olfactory and prosocial (PS) cores, which permits the expression of social monogamy in males; and how differential connectivity accounts for differential expression of prosociality and aggression.Using resting-state functional magnetic resonance imaging, we integrated graph theory analysis to compare functional connectivity between two culturally/behaviorally distinct male prairie voles (Microtusochrogaster).Illinois males display significantly higher levels of prosocial behavior and lower levels of aggression than KI (Kansas dam and Illinois sire) males, which are associated with differences in underlying neural mechanisms and brain microarchitecture. Shared connectivity 1) between the anterior hypothalamic area and the paraventricular nucleus and 2) between the medial preoptic area and bed nucleus of the stria terminalis and the nucleus accumbens core suggests essential relationships required for male prosocial behavior. In contrast, Illinois males displayed higher levels of global connectivity and PS intracore connectivity, a greater role for the bed nucleus of the stria terminalis and anterior hypothalamic area, which were degree connectivity hubs, and greater PS and olfactory intercore connectivity.These findings suggest that behavioral differences are associated with PS core degree of connectivity and postsignal induction. This transgenerational system may serve as powerful mental health and drug abuse translational model in future studies.

Although previous research has found that prosocial behavior increases personal and relationship well-being, a particularly costly type of prosocial behavior — sacrifice — can sometimes have aversive effects and is the focus of the current review. We consider effects for both the individual who enacts the sacrifice and the recipient. Sacrifice, can take a toll on the giver's well-being, is a mixed blessing for the recipient (when they perceive the sacrifice), and may have some harmful consequences for relationships in the long-run. We discuss the importance of finding the right strategies (e.g. alternative solutions, comparison of costs and rewards between partners, reappraisals) to navigate these complex interpersonal situations in which partners' goals and preferences conflict.

The field of prosociality is flourishing, yet researchers disagree about how to define prosocial behavior and often neglect defining it altogether. In this review, we provide an overview about the breadth of definitions of prosocial behavior and the related concept of altruism. Common to almost all definitions is an emphasis on the promotion of welfare in agents other than the actor. However, definitions of the two concepts differ in terms of whether they emphasize intentions and motives, costs and benefits, and the societal context. In order to improve on the conceptual ambiguity surrounding the study of prosociality, we urge researchers to provide definitions, to use operationalizations that match their definitions, and to acknowledge the diversity of prosocial behavior.

Prosociality is an important part of the work context. For instance, employees, leaders, and organizations show various forms of prosocial behavior such as supporting colleagues suffering from heavy workload, voluntarily organizing social events fostering a good organizational climate, or providing goods and services that benefit society at large. From the plethora of constructs related to prosociality at work, I herein provide a brief introduction to the currently most prominent ones with regard to organizational members in general (organizational citizenship behavior) and leaders (servant leadership), respectively. Moreover, I briefly sketch how research on prosociality at work would probably profit from a stronger integration of research from related fields, within and beyond the organizational literature.

The extant literature is mostly dichotomized in examining the effect of either prosocial behavior on well-being or well-being on prosocial behavior. After reviewing the emerging line of research on the positive feedback loop between prosocial behavior and well-being, I integrate all up-to-date empirical findings to present a reciprocal model where prosocial behavior begets well-being and well-being begets prosocial behavior. This article provides fresh insights, including the moderating roles of prosocial behavior and well-being and fading (and anti-fading) of the positive feedback loop. I also offer various promising lines of inquiry for future work and highlight powerful and ecologically valid research designs, such as experience-sampling studies and multiple-time point field experiments to capture the dynamic interplay between prosocial behavior and well-being.

Personality disorders (PDs) are characterized by interpersonal dysfunction, and deficits in prosociality are theorized to contribute to this. We review studies linking categorical PDs to prosocial and antagonistic traits and highlight studies that assessed prosocial behavior in PDs via economic games. We structure our review based on the recently proposed affordance framework of prosocial behavior, summarizing evidence for exploitation, reciprocity, temporal conflict, and dependence under uncertainty as situational affordances allowing the expression of personality in prosocial behavior. We conclude that some of the inconsistencies in the literature may be due to studies focusing on different situational affordances and the reliance on categorical PDs. We suggest a research agenda and a set of testable hypotheses based on maladaptive personality traits included in the newly implemented dimensional PD diagnoses in ICD-11 and DSM-5.

Antibiotic prescribing can be conceptualised as a social dilemma in which the overuse of antibiotics, to minimise immediate risks to individual patients, results in a sub-optimal outcome for society (antimicrobial resistance) and increased risks to all patients in the long run. Doctors face the challenge of balancing the interests of individual patients against the collective good when prescribing antibiotics. While evidence suggests that doctors tend to prioritise individual interests over those of the collective, the conventional interpretation of such decisions as selfish may be inappropriate, because most doctors are motivated by prosocial concerns about their patients. This review of antibiotic decision research provides a more nuanced understanding of prosociality in the context of the social dilemma of antibiotic prescribing.

Reward and punishment change the payoff structures of social interactions and therefore can potentially play a role in promoting prosocial behavior. Yet, there are boundary conditions for them to be effective. We review recent work that addresses the conditions under which rewards and punishment can enhance prosocial behavior, the proximate and ultimate mechanisms for individuals’ rewarding and punishing decisions, and the reputational and behavioral consequences of reward and punishment under noise. The reviewed evidence points to the importance of more field research on how reward and punishment can promote prosocial behavior in real-world settings. We also highlight the need to integrate different methodologies to better examine the effects of reward and punishment on prosocial behavior.

Recently Press and Dyson have dramatically changed our view on the Prisoner's Dilemma by proposing a new class of strategies that enforce a linear relationship between the two players' scores. Players adopting ‘extortion’ respond with cooperation to cooperation in most cases, defect in other rounds, but respond to defection with defection. In this way, extortion enforces full cooperation of the partner who accedes to it because he profits from doing so. This unbeatable strategy is nevertheless prosocial because it is mostly cooperative and induces cooperation even though it gains most itself. Experiments show that about 40% of humans choose to use extortion in competitive situations or when they have the power to exchange coplayers. On being punished in egalitarian situations, they use a generous strategy.

Theory and experiments suggest people have different strategies (1) to condition their prosocial behavior in ways that maximize individual benefits and (2) to punish others who have exploited their own and others’ prosocial behaviors. To date, most research testing existing theories has relied on experiments. However, documenting prosocial and punishment behaviors outside of the laboratory via experience sampling and diary methods can yield additional, rich insights. Recent work demonstrates these methods can describe social behaviors in daily life and be used to test theory about how behaviors change across situations and relationships. These methods have exposed discrepancies between what people experience in daily life and the problems researchers want to solve to understand the nature of human prosociality.

This review compiles and contextualizes the available empirical literature on natural occurrences of high-stakes altruism among nonrelatives, i.e., behaviors often called ‘heroic’. Four domains are covered: exceptional bravery and self-sacrifice in war, heroism in civilian life, undirected organ donations, and rescues of persecuted persons during mass violence and genocides. The diversity of strategies used to identify instances of heroic behavior and the multiplicity of data collection methods employed in this relatively sparse literature currently preclude a systematic comparison of results. Therefore, the aim of this overview is to provide an exhaustive point of entry to a fascinating field of research with much untapped potential for testing theories about prosocial behavior.

Children act prosocially already in their first years of life. Research has shown that this early prosociality is mostly motivated by sympathy for others, but that, over the course of development, children's prosocial behaviors become more varied, more selective, and more motivationally and cognitively complex. Here, we review recent evidence showing that starting at around age 5, children become gradually capable of strategically using prosocial acts as instrumental means to achieve ulterior goals such as to improve their reputation, to be chosen as social partners, to elicit reciprocity, and to navigate interpersonal obligations. Children's sympathy-based prosociality is thus being extended and reshaped into a behavioral repertoire that enables individuals to pursue and balance altruistic, mutualistic, and selfish motives.

One reason people engage in prosocial behavior is to reap the reputational benefits associated with being seen as generous. Yet, there isn't a direct connection between doing good deeds and being seen as a good person. Prosocial actors are often met with suspicion and sometimes castigated as disingenuous braggarts, empty virtue-signalers, or holier-than-thou hypocrites. In this article, we review recent research on how people evaluate those who engage in prosocial behavior and identify key factors that influence whether observers will praise or denigrate a prosocial actor for doing a good deed.

Some moral actions - including prosocial actions - are more exceptional than others. Within psychology, interest in such moral exceptionality is mounting, but a definition of the concept is lacking. Our review addresses this issue by integrating insights from the moral exemplar, heroism, and supererogation literatures. We propose an action-based definition that places the outperformance of prescriptive or descriptive moral norms at the core of moral exceptionality. Using our definition, we i) discuss how exceptionality is represented in moral constructs studied across psychology and ii) provide a template for identifying moral exceptionality in the prosocial domain.

Adults often understand their lives by constructing personal stories and then living into them. Time and time again, a positive relation has been found between the tendency to build redemptive personal stories wherein negative and challenging experiences ultimately give way to positive endings and prosocial behavior. Here, I review the relevant literature in the interest of advancing the notion that redemptive stories and prosociality exist in a virtuous cycle. Engaging in prosocial acts can stimulate the redemptive framing of one's past. By the same measure, once formed, individuals work to bring the story to life, and the ethos of redemption holds the potential to stimulate and sustain prosocial behavior.

Direct and indirect reciprocity are two fundamental mechanisms that promote prosocial behavior within groups and across societies. Here, we review recent work that illustrates how a (direct and indirect) reciprocity framework can illuminate our understanding of several factors related to prosocial behavior — namely group membership, gossip, and third-party punishment. We propose that each of these factors can promote prosocial behavior via proximate psychological mechanisms related to direct and indirect reciprocity: reputational concern, expectations, and anticipation of future interaction. Finally, we discuss the implications of adopting such a framework and highlight a number of avenues for future research.

Gratitude promotes well-being, but people may not express it even when they feel it. A core aspect of rational behavior is that people make decisions based on the expected value of their actions. While acting on expectations may be rational, the choices one makes may not be optimal if those expectations are misguided. Because people underestimate the benefit and overestimate the cost of expressing gratitude, miscalibrated predictions can create a misplaced barrier to gratitude expression. These mistaken beliefs about interpersonal interactions stem partly from a perspective-based asymmetry between actors and targets. The propensity to undervalue one's positive impact on others may reflect a broader tendency that undermines prosociality in daily life - to the detriment of one's own, and others', well-being.

Stress under extreme conditions can promote not only negative reactions but also prosocial behaviour or provision of protection and social support. This study presents research aimed at detecting the ‘tend-and-befriend’ stress response among crewmembers of the SIRIUS-19 international spaceflight simulation (120 days, 3 men, 3 women). Emotional energy proved to be a good indicator of individual capability to emotionally invest in relationships with crewmates. To measure emotional energy, we applied a subscale of Shirom-Melamed Vigor Measure. Personal Self Perception and Attitudes computerised test and sociometry were used to assess cohesion and psychological closeness in the crew. The results show a high level of emotional energy invested by the crew in their crewmates. Crew cohesion, assessed on the basis of reciprocal sociometric choices, and psychological closeness, measured as perceived similarity, both tended to increase during the isolation experiment. In a mixed crew, both men and women showed high levels of emotional energy and social support. It seems therefore that in a cohesive crew, emotional relationships – expressed in increased psychological closeness, emotional energy, and the tend-and-befriend behaviour (provision of mutual protection and assistance) – represent the dominant prosocial response to the challenge of social isolation. This line of research deserves further development in the context of simulated space flights and would profit from further work on instruments aimed at a deeper analysis of emotional relationships in small isolated groups.

Desensitization, the reduction of cognitive, emotional, and/or behavioral responses to a stimulus, is an automatic and unconscious phenomenon often experienced in everyday life. Exposure to violent media, especially violent video games, may cause desensitization to real-life violence. Desensitization to violence blocks empathy which is needed to trigger the moral reasoning process that triggers prosocial responding. Representative research was reviewed to examine links between exposure to violent video games and desensitization to violence in children and adolescents. It was concluded that exposure to violent video games increases the risk of desensitization to violence, which in turn may increase aggression and decrease prosocial behavior. Parents should be counseled to discuss the differences between real and screen violence, to encourage nonviolent problem-solving, and to provide empathy-building experiences for their children.

Although, sustainable consumption is gaining in relevance for consumers and retailers in Germany, pro-social consumption is still often neglected. Therefore, this study investigates factors influencing the purchase intention of German flower buyers in relation to Fairtrade-cut roses based on an online survey of 1,201 flower buyers in retail shops in 2017. As a basic theoretical framework, the Theory of Planned Behavior (TPB) was utilized and extended with two additional constructs. The addition of emotions and perceived consumer effectiveness reveals a strong explanatory power of the model proposed. Data analysis via partial least square structural equation modeling (PLS-SEM) suggests that emotions and subjective norm are the two most influential determinants of intention to purchase Fairtrade roses. However, emotions also significantly influence all determinants of behavioral intention introduced to the extended model. The findings of this study can be used to fine-tune marketing and communication activities related to pro-social and Fairtrade products.

Time pressure could make drivers exhibit more risky driving behaviour. Attitudes can influence people’s behaviours, but few studies have explored the influence of prosocial attitudes on driving behaviour. The purpose of this study was to explore the influence of prosocial attitudes on driving behaviour under time pressure. A 2 (high/low prosocial attitude) *2 (present/no time pressure) mixed design was used to investigate the interaction between prosocial attitude and time pressure on driving behaviour. Prosocial attitudes and time pressure have a significant main effect on driving behaviour. Drivers with high prosocial attitudes made lane changes at a greater distance from pedestrians and decelerated to a greater degree than drivers with low prosocial attitudes when interacting with pedestrians. Under time pressure, people drive faster and accelerate more quickly. Specifically, we found an interaction between time pressure and prosocial attitudes on driving behaviour. Drivers with low prosocial attitudes showed higher speeds than drivers with high prosocial attitudes under the time pressure scenario on foggy roads. The results showed that high prosocial attitudes lead to friendly interactions with pedestrians and careful driving in specific situations, even under time pressure. The present study not only expands the research on driving behaviour and attitude but can also provide some data support and guidance for driver selection and training.

This research project aims to know the effectiveness of autogenic meditation training on selective and sustained attention, state and trait anxiety and a set of emotional and behavioral symptoms in a Spanish scholar population sample. DESIGN: Multi-arm randomized controlled trial through three parallel conditions: 1. Autogenic meditation training program: AMT; 2. Natural reading training program: NRT (active control); and 3. Waiting list (passive control). MEASURES: Selective and sustained attention (Tot and Con indexes respectively) assessed using the d2 test of attention (Brickenkamp, 1962) in its Spanish adapted version (Seisdedos, 2002; State anxiety and trait anxiety indexes assessed employing the state-trait anxiety inventory for children: STAIC (Spielberger, 1973)in its adapted version to the Spanish population (Seisdedos, 1990). Emotional symptoms (ES), behavioral problems (BP), hyperactivity–inattention (HI), peer relationship problems (PR), total difficulty index (DS) and prosocial behaviors (PB), assessed utilizing the Strengths and Difficulties questionnaire: SDQ (Goodman, 1997) for Spanish population (Gomez-Beneyto et al., 2013). HYPOTHESIS: 1) AMT, unlike NRT or passive control, will improve selective and sustained attention. 2) AMT, unlike NRT or passive control, will reduce state and trait anxiety. 3) AMT, unlike NRT or passive control, will minimize emotional symptoms, behavioral problems, hyperactivity-inattention, peer relationship problems and difficulty score, and promote prosocial behavior; and hence will provide a better profile or adjustment of mental health. Files description Detailed protocol of the procedure with each group. This protocol includes autogenic meditation program and the detailed account of the training workshop, and also natural reading program, and the detailed account of the training workshop. Dataset. This dataset includes pre and post scores of the participants in the d2 test, in the state-trait anxiety inventory for children (STAIC), and the strengths and difficulties questionnaire (SDQ).

The aim of this paper is to investigate the effect of different factors like Religiosity, Social Class, Social Capital, Financial Capital, and Human Capital, on prosocial behavior. We proposed a theoretical framework hypothesizing a positive effect of these factors in enhancing compassion, and in turn affecting prosocial behavior. Factors of prosocial behavior included (Helping Behavior, Charitable Donation, and Volunteering). Empirical validity was established by conducting a survey using a close-ended questionnaire. Data were collected from 450 respondents and analyzed using confirmatory factor analysis and structured equation modeling. We found that Result showed that religiosity and financial capital significantly impact on compassion. Whereas compassion having a significant effect on helping behavior. Financial capital and religiosity significantly effect on helping behavior also seem to be directly affecting helping behavior. Volunteering and charitable donations do not seem to get affected either indirectly or indirectly by any of the factors. This study will help the charitable organization to build and maintain the charity norms and helping & prosocial behavior in Pakistan.

Multiple studies suggest that, contrary to economic rationale, offering monetary incentives to complete a task can negatively affect task performance. This phenomenon is attributed to so-called crowding-out effects, in which monetary rewards “crowd out” non-monetary sources of value that people derive from task completion (e.g., intrinsic value of the task; social recognition). Yet, recent work calls the validity of crowding-out effects into question. In this study, we revisit a well-known field experiment by Gneezy and Rustichini (2000) that provides evidence for crowding-out effects in the context of prosocial behavior. We test the robustness of these effects using a larger sample and adjust the experiment’s design to better elucidate the role of non-monetary incentives in prosocial behavior. Specifically, we give 245 pairs of high school students different incentives to collect donations for charity: low monetary incentives (1% of the total donations collected), high monetary incentives (10% of the total donations collected), non-monetary incentives (a better sense of the task’s importance and public recognition), or no external incentives. In line with crowding-out effects and Gneezy and Rustichini's (2000) findings, our results show that low monetary incentives elicit lower performance (collected donations) compared with the absence of external incentives. Importantly, non-monetary incentives elicit higher performance compared with either monetary incentive or the absence of external incentives.

This paper experimentally investigated luck framing. Specifically, we analyzed the difference between being assigned an advantageous role in a distribution game and being assigned the same role while being explicitly told that you were lucky to be in that favorable position. We tested this difference by implementing a dictator game and a no-veto-cost ultimatum game. We observed that: a) dictators transferred larger amounts in the game when they were explicitly told they were lucky to be the dictator compared to dictators who did not receive this message, and b) responders in the no-veto-cost ultimatum game who were explicitly told they were lucky to be in that role were significantly less likely to reject a particular offer compared to responders in the game who did not receive this message. The combination of these results is consistent with the hypothesis that people are more likely to behave in a more prosocial and egalitarian manner when they are reminded that they are lucky to be in a particular position.

Two types of social policy instruments — making group behavior public to the individual and making individual behavior public to the group — are used by charities to encourage giving and by policymakers to incentivize other prosocial behaviors. However, models of social norms suggest that the effects of such interventions are theoretically ambiguous and may even backfire in low-compliance environments. We examine these questions in the context of a public good game. Exploiting a unique experimental design, we show that initial contributors' giving decisions are sensitive to the behavior of the group while initial non-contributors' decisions are not. In contrast, making own behavior public to the group increases contributions for all group types, even those comprised entirely of initial non-contributors. These findings suggest that publicizing contributions causes individuals to respond to a common understanding of prosocial behavior that is not defined solely by the initial group norm.

Borderline personality disorder (BPD) and persistent depressive disorder (PDD) are related to interpersonal dysfunction which might become particularly apparent in situations of social exclusion (SE). While emotional responses to SE have been widely explored, behavioral data in clinical samples are lacking. In this cross-diagnostic study, we applied a variant of the Cyberball paradigm to investigate the dynamic behavioral response to partial SE in BPD and PDD. BPD patients (n = 36), PDD patients (n = 34) and age and gender matched healthy controls (HC) (total n = 70) played experimental (i.e. partial SE Cyberball) and control (i.e. inclusion only) conditions in randomized order. While all groups tended to increase ball tosses towards the excluder in response to SE, this behavioral turn was significantly lower in PDD (p = .03, d = -.30) and trendwise in BPD patients (p = .06, d = -.28). Thus, an altered immediate response to partial SE was observed in BPD and PDD, in addition to the emotional reactions. This study supports the hypothesis of a behavioral coping with SE in BPD and PDD that might be problematic in the long run and provides an experimental paradigm for future research on interpersonal dysfunction.

‘Altruism born of suffering’ (ABS) predicts that, following an adverse life event such as a health shock, individuals may become motivated to help others and act pro-socially. However, despite anecdotal support this has not been examined systematically. Using data from the United States Panel Study of Income Dynamics, we find that an adverse health shock does not lead to a general increase in pro-social behaviour; it neither causes people to start giving, nor does it spark an increase in donations across charitable causes. Instead, ABS is akin to a specific shock that affects giving to health charities. We find a significant increase in the probability of giving to health charities, with no change for other charity types. Accompanying this is an increase in amounts given to health charities, which comes at the expense of non-health, non-religious charities. The impact is greatest in the year after the health shock, attenuating thereafter.

We present experimental evidence on how pro-sociality, trust and attitudes towards risk and ambiguity evolved over the six weeks following the imposition of stringent Covid-19 related lockdown measures in the Hubei province of China. We compare incentivized economic decision-making in a baseline sample, collected pre-epidemic, with a series of repeated cross-sectional samples drawn from the same population between January and March, 2020. We find high rates of altruism, cooperation and aversion to risk taking under ambiguity in the immediate aftermath of the lockdown, while trust is significantly below its baseline level. Risk attitudes also differ in the post-lockdown sample, with decreased risk tolerance in the loss domain and lesser risk aversion in the gain domain. We further uncover significant transitory effects for trust and risk aversion around the date of a high-profile whistleblower's death from Covid-19. Our findings suggest that the onset of a public health crisis may have unintended consequences for economic preferences that determine population compliance with interventions designed to reduce the spread of a novel coronavirus.

Traditionally, charities that seek donations for human-suffering causes have relied heavily on emotional appeals designed to motivate negative feelings such as sadness and fear. Past research supports a sympathy-helping hypothesis that donation campaigns that use images of human-suffering to evoke sympathy and empathy increase prosocial behaviors. Empirical evidence also supports an inspiration-helping hypothesis whereby the positive emotion of strength inspires people to donate. Consistent with the proposed sympathy + inspiration-helping hypothesis, appeals that combine hope and sadness (vs. hope-dominant and sadness-dominant appeals) elicit sympathy and inspiration that motivate increased donations toward human-suffering causes. In addition, Study 2 results support that improving emotion appeals (sad to hopeful) generate higher donations than declining emotion appeals (hopeful to sad). Study 3 shows that cognitive load moderates the emotion-donation relationship. Under high load when mental resources are constrained, donations declined for the sadness + hope mixed emotion appeal.

Limited prosocial emotions (LPE) are characterized by a lack of remorse or guilt, callousness/lack of empathy, being unconcerned about performance, and shallow/deficient affect. While previous research has largely focused on the presence or absence of LPE in youth, there is considerable evidence that symptom presence/absence and symptom impairment are separable dimensions, where impairment often is found to play a significant, unique role in assessing child psychopathology. The current study utilized a newly developed questionnaire with the purpose of exploring its psychometric properties and better understand the dual and potentially differential role LPE symptom presence and LPE-related impairment have in youth. Mothers (n = 265) of children (Mage = 8.04, SD = 2.07) completed questionnaires assessing LPE impairment, LPE symptoms, externalizing disorder symptoms, and functional impairment. Results demonstrated strong support for the psychometric properties of the newly developed measure of LPE impairment. Importantly, LPE-related impairment uniquely predicted all impairment domains above-and-beyond the effects of LPE symptoms, oppositional defiant disorder, and CD symptoms (as well as child age and sex covariates). Moreover, youth in the top 25th percentile on both LPE symptoms and LPE-related impairment (compared to youth only in the top 25th percentile in LPE symptoms) had greater mean externalizing symptoms and functional impairment. The preliminary evidence provided suggests researchers and clinicians may benefit from assessing both LPE symptoms and LPE-related impairment when attempting to identify youth with high levels of conduct problem symptoms and/or psychosocial impairment. Future research should aim to replicate and expand our findings to other clinical populations.

We review research on personality/religiousness associations, integrating earlier meta-analyses with recent large-sample online studies. We find that general religiousness shows small positive associations with broad personality factors (e.g. HEXACO Honesty-Humility, Big Five Agreeableness, Conscientiousness) and somewhat stronger positive associations with narrower personality traits involving prosocial tendencies (e.g. altruism, fairness, forgivingness). The link between religiousness and prosociality appears not to be an artifact of self-report method variance. Religious fundamentalism and spirituality show negative and positive associations, respectively, with the Openness factor of personality. Religiousness/personality associations tend to be weak in relatively non-religious countries but moderately strong in highly religious countries. The direction of causal influence between personality and religiousness is not yet clear. Religiousness shows modest negative associations with IQ and appears to be somewhat negatively related to scientific thinking.

I study the first case of a large-scale land tenure reform implemented as a randomized control-trial in rural Benin to isolate the effects of formalizing property rights on trust and cooperation. The reform transformed informal and collective land tenure by registering individual rights over land and making it possible to sell, collateralize, and defend these rights in court. Seven years after the intervention, results of a public goods game and a trust game show that cooperation and trust substantially increase but only for participants in villages served by paved roads who can benefit from access to institutions and government services introduced by the reform. Conversely, in more isolated communities characterized by larger costs to access institutions, the reform significantly reduced prosocial behavior. An analysis of possible mechanisms suggests that subjects in isolated villages perceived the reform as facilitating institutional shopping for wealthy individuals, thus sparking resentment against the replacement of the customary conflict resolution system and increasing the support for banning the land market.

This paper examines how decision-making may change when individuals face a permanent change in financial resources after a major life transition. We experimentally elicit preference and cognitive measures from Colombian students on the job market, as well as from a comparison group of college peers in lower years, over 8 months. This period encompasses the job search process while students are in college and ends after they graduate and begin their full-time jobs. Using a difference-in-differences setup, we find that students entering the job market perceive greater financial liquidity and take on more responsibilities. We do not find any evidence of an increase in the take-up of credit or of students moving out of their parents’ homes, features commonly associated with this transition in other countries. Regarding preferences, we find suggestive evidence that the students become less present biased and more prosocial during this transition to the workforce. We do not find significant changes in risk and ambiguity preferences or cognitive performance. These findings help us document the changes experienced during a universal transition, one that is achieved through own effort rather than cash transfers or government policies.

Purpose This study examines the mental health impact of the COVID-19 pandemic on adolescents in the United Kingdom as well as social, demographic, and economic variations in the impact. Methods Nationally representative longitudinal panel data from the Understanding Society COVID-19 survey were analyzed. The analytical sample comprises 886 adolescents aged 10–16 years surveyed both before and during the pandemic. The Strengths and Difficulties Questionnaire was used to measure adolescents' mental health. Results The results from person fixed-effects regression models show that adolescents with better-than-median mental health before the pandemic have experienced an increase in their emotional problems, conduct problems, hyperactivity, and peer relationship problems, but a decrease in their prosocial tendency during the pandemic. In contrast, adolescents with worse-than-median mental health before the pandemic have experienced opposite changes in each Strengths and Difficulties Questionnaire domain. Further results from lagged dependent variable regression models show that compared with girls, boys have experienced a smaller increase in emotional problems but a greater decrease in prosocial tendency. The negative mental health impact is particularly prominent among adolescents in one-parent, one-child, and low-income households. Adult household members' COVID-19 symptoms and illness have undermined adolescents' peer relationships. Conclusions The results reveal the pandemic's diverse impacts on adolescent mental health, which vary with adolescents' prepandemic mental health and sociodemographic backgrounds. The findings underline the need for tailored mental health support for adolescents and targeted measures to mitigate inequalities in the mental health impact of the pandemic.

Sharing platforms struggle to remain financially viable and preserve their prosocial and environmental aspirations; therefore, effort to empirically study successful sharing economy business models (SEBMs) is needed. The aim of this research is to identify business model patterns among existing SEBMs in order to suggest business model attributes that support successful implementation. Patterns describe one or several recurring business model attributes observed among existing business models. This study investigates 63 SEBMs across 93 different configuration options. The k-medoids clustering approach was used to identify configuration options recurring repeatedly across the data. The empirical results were triangulated with existing business model patterns from literature. The study presents a framework to describe and analyse SEBMs; eight prototypical patterns, with a corresponding list of relevant business model attributes; and six solution patterns unique to the sharing economy. The patterns – as well as insights across locations, shared practices, and platform types – advance knowledge on the sharing economy. Furthermore, these patterns support sharing platforms to communicate, learn, and experiment, ideally supporting successful implementation of SEBMs.

Indirect reciprocity – the notion that third-party observers offer rewards to prosocial actors – is known to increase levels of cooperative behavior. Yet we know relatively little about how people decide to grant indirect reciprocity. This process is complex because it relies on assessing moral character, which is unobservable. In the current research, we identify a salient cue in the social environment that observers use to calibrate their indirect reciprocity: power differences. Across three experiments, observers were less likely to offer indirect reciprocity to employees who targeted their generosity toward higher- rather than lower-power co-workers. Indirect reciprocity was measured through the allocation of participants’ own financial resources (Experiments 1 and 2), as well as behavioral intentions (Experiment 3). Experiment 3 also showed that this effect is driven by observers’ perceptions of actors’ motives, which inform assessments of moral character.

Prosocial acts typically take the form of time- or money-donations. Do third-parties differ in how they evaluate these different kinds of donations? Here, we show that people view time-donations as more morally praiseworthy and more diagnostic of moral character than money-donations, even when the resource investment is comparable. This moral preference occurs because people perceive time-donations as signaling greater emotional investment in the cause and therefore better moral character; this occurs despite the (correct) belief that time-donations are typically less effective than money-donations (Study 1). This effect in turn is explained by two mechanisms: People believe that time-donations are costlier even when their objective costs are equated, which happens because people rely on a lay theory associating time with the self (Study 2). The more signaling power of time-donations has downstream implications for interpersonal attractiveness in a dating context (Study 3A), employment decisions (Study 3B), and donor decision-making (Study 3). Moreover, donors who are prompted with an affiliation rather (versus dominance) goal are likelier to favor time-donations (Study 4). However, reframing money-donations in terms of time (e.g., donating a week’s salary) reduced and even reversed these effects (Study 5). These results support theories of prosociality that place reputation-signaling as a key motivator of moral behavior. We discuss implications for the charity market and for social movements, such as effective altruism, that seek to maximize the social benefit of altruistic acts.

Background This study aims to explore the mediational effects of emotional and behavioral problems on the association between childhood emotional abuse and depressive symptoms among college students. Methods Data were drawn from 60 universities from 10 provinces in China (n=30,374). Information about childhood maltreatment, depressive symptoms, emotional and behavioral problems were gathered through the Childhood Trauma Questionnaire-Short Form (CTQ-SF), the Center for Epidemiologic Studies Depression Scale (CES-D) and the Strengths and Difficulties Questionnaire (SDQ), respectively. Univariable and multivariable logistic regression models and mediating models were used. Results After controlling for demographic factors, childhood emotional abuse was the strongest risk factor for depressive symptoms (adjusted odds ratio (aOR)=2.54, 95%CI=2.27-2.85). The relationship between childhood emotional abuse and depressive symptoms was partially mediated by emotional and behavioral problems with 68.7% total indirect effect. Among the 5 identified subtypes of emotional and behavioral problems, the mediating effects of emotional problems (57.3%) and hyperactivity (28.6%) were higher than peer problems (7.8%) and prosocial behavior (3.6%). Conduct problems did not show a significant mediating effect (p>0.05). Limitations The cross-sectional design is limited to make inferences about causality. Conclusions Childhood emotional abuse was strongly associated with depressive symptoms in college students. Of the five identified subtypes of emotional and behavioral problems, four subtypes mediated the relationship between childhood emotional abuse and depressive symptoms, including emotional problems, hyperactivity, peer problems and prosocial behavior.

As the influence of online consumer reviews grows, deceptive reviews are a worsening problem, betraying consumers' trust in reviews by pretending to be authentic and informative. This research identifies factors that can separate deceptive reviews from genuine ones. First, we create a novel means of detection by contrasting authentic versus fake word patterns specific to a given domain (e.g., hotel services). We use a survey on a crowdsourcing platform to obtain both genuine and deceptive reviews of hotels. We learned the word patterns from each category to discriminate genuine reviews from fake ones for positively and negatively evaluated reviews, respectively. We show that our All Terms procedure outperforms current benchmark methods in computational linguistics and marketing. Our extended analysis reveals the factors that determine fake reviews (e.g., a lack of details, present- and future-time orientation, and emotional exaggeration) and the factors influencing people's willingness to write fake reviews (including social media trust, product quality consciousness, deal proneness, hedonic and utilitarian consumption, prosocial behavior, and individualism). We also use our procedure to analyze more than 250,000 real-world hotel reviews to detect fake reviews and identify the hotel and review characteristics influencing review fakery in the industry (e.g., star rating, franchise hotel, hotel size, room price, review timing, and review rating).

Prosocial behaviors are essential for group cooperation, which enrich life experience and enhance survival. These complex behaviors are governed by intricate interactions between numerous neural circuits functioning in concert. Impairments in prosocial interactions result from disruptions of this coordinated brain activity and are a prominent feature of several pathological conditions including autism spectrum disorder, depression and addiction. Here we highlight recent studies that use advanced techniques to anatomically map, monitor and manipulate neural circuits that influence prosocial behavior. These recent findings provide important clues to unravel the complexities of the neural mechanisms that mediate prosocial interactions and offer insights into new strategies for the treatment of aberrant social behavior.

Empathy is an essential function for humans as social animals. Emotional contagion, the basic form of afffective empathy, comprises the cognitive process of perceiving and sharing the affective state of others. The observational fear assay, an animal model of emotional contagion, has enabled researchers to undertake molecular, cellular, and circuit mechanism of this behavior. Such studies have revealed that observational fear is mediated through neural circuits involved in processing the affective dimension of direct pain experiences. A mouse can also respond to milder social stimuli induced by either positive or negative emotional changes in another mouse, which seems not dependent on the affective pain circuits. Further studies should explore how different neural circuits contribute to integrating different dimensions of affective empathy.

High traffic density may lead to more traffic accidents because of more frequent lane change and overtaking behaviors, but drivers with different characteristics may exhibit different driving behaviors. The present study explored the difference in driving behaviors between drivers with a high/low prosocial attitude under high/low traffic density. In this study, a 2 (high/low prosocial attitude) *2 (high/low traffic density) mixed design was used to investigate the interaction between prosocial attitude and traffic density on lane change and overtaking behavior. The implicit association test paradigm was used to measure prosocial attitude, and drivers were divided into two groups. Forty subjects were asked to complete simulated driving tasks under the two conditions of high and low traffic density, and driving behaviors were recorded by driving simulators. The results show that high traffic density leads to more lane change and overtaking behavior. Drivers with a high prosocial attitude have better driving performance under both high and low traffic density, but drivers with a low prosocial attitude maintain a smaller transverse distance from adjacent vehicles in high traffic density, which may increase risk. This study provides support for the selection, training and intervention of professional drivers.

We propose a dynamic model of moral decision making whereby people revise their morally relevant preferences as their options evolve. We employ this model to reinterpret prior findings on moral hypocrisy. In particular, we revisit the finding that, when tasked to assign themselves and another person to tasks that differ in pleasantness, participants who “flip a coin” to determine the task allocation assign themselves to the preferable task more than fifty percent of the time. This result was originally thought to reveal that people will take moral credit for flipping a coin while simultaneously harboring the intention of disregarding its outcome if it is negative. We suggest instead that people flip the coin not with the intention of disregarding the outcome, but with the hope of maximizing their self-interest without self-reproach (Studies 1 and 2); only when this outcome proves unachievable do they resort to rationalizing their self-interested assignment (Studies 3 and 4). These findings offer a novel perspective on the flexibility of moral decisions.

The design of effective incentive schemes that are both successful in motivating employees and keeping down costs is of critical importance. Research has demonstrated that prosocial incentives, where individuals’ effort benefits a charitable organization, can sometimes be more effective than standard monetary incentives. However, most research has focused on the intensive margin, examining effort conditional on participation in the activity. We examine the effectiveness of standard and prosocial incentives on the extensive margin, corresponding to people’s decisions to opt-in to an incentivized activity. In addition, we test the effectiveness of optional prosocial incentives, where individuals can choose between keeping or donating all or part of their payment. Across four experiments that vary the type and size of incentives, we find that individuals are more likely to avoid activities that involve any prosocial incentive. Our results highlight the importance of considering the margin of decisions when designing incentive schemes.

This research draws on signaling theory to investigate the impact of corporate sponsorship of nonprofits on consumer prosocial behavior. Across two experiments, the authors examine how information about the sponsorship engagement of a nonprofit organization and people’s degree of familiarity with the nonprofit influence their willingness to engage in prosocial behavior toward the nonprofit. Study 1 shows that consumers are more willing to offer support to a nonprofit if they believe the nonprofit has extensive sponsorship engagement. Further, Study 1 shows that people’s perceptions of their donations’ impact on the nonprofit transmit the positive effects of sponsorship engagement to willingness to donate. Study 2, which is based on different sponsorship rosters and different measures, confirms Study 1 findings regarding the direct effects of sponsorship engagement on willingness to support and the indirect effects on willingness to donate. Implications for corporate sponsors and nonprofits are discussed.
