The Psychological Consequences of Money

How effort-based self-interest motivation shapes altruistic donation behavior and brain responses

Prosocial behaviors are central to individual and societal well-being. Although the relationship between effort and prosocial behavior is increasingly studied, the impact of effort-based self-interested motivation on prosocial behavior has received less attention. In the current study, we carried out two experiments to examine the effect of motivation to obtain a reward for oneself on donation behavior and brain response. We observed that individuals who accumulated more money in the effort-expenditure rewards task (EEfRT) donated a lower proportion of their earnings. The sigmoid model fitted participants' choices in the EEfRT task, and the effort-reward bias and sigma parameters negatively correlated with the amount of money donated in the donation task. Additionally, the effort-reward bias and sigma parameters negatively predicted N2 amplitude during processing of charitable donation-related information. We propose that individuals who exhibit a lower level of effort-based self-interest motivation may allocate more cognitive control or attentional resources when processing information related to charitable donations. Our work adds weight to understanding the relationship between effort-based self-interest motivation and prosocial behavior and provides electrophysiological evidence.

Impact of COVID-19 pandemic on road traffic injuries in Iran: An interrupted time-series analysis

INTRODUCTION

Globally, the COVID-19 pandemic has affected the number of road accidents and deaths caused by them. The present study aimed to identify the effect of this epidemic on traffic accidents and their casualties in Iran.

METHODS

In this study, Interrupted Time Series Analysis (ITSA) was used in a semi-experimental design to measure the impact of the restrictive policies of COVID-19 on road accidents. Data were collected retrospectively from the Iran Red Crescent Society data set for 31 provinces from March 2017 to February 2022. The information related to the number of road accidents, injuries, deaths, and deaths in the hospital was collected. The Newey-West method is used for estimation. Statistical analyses were carried out using R software version 3.6.1.

RESULTS

Since February 2020 in Iran, the reduction in the number of road accidents and the number of injuries and deaths in these accidents was significant at 5% but the reduction of deaths in the scene and hospital was significant at 10%. In general, for all variables, the reduction trend was established only in the first months, and then it had an upward trend.

CONCLUSION

In the early months of the COVID-19 epidemic in Iran, the number of road accidents and their casualties decreased. Policies restricting traffic, quarantine, and fines for violators can be reasons for changing people's behavior and travel patterns and also lead to a reduction in traffic accidents and fatalities. Such studies can explain the importance of the policies in changing behavioural patterns and can be used as a guide in future policies.

Beyond monetary value: how reward type drives cheating in a gender-judgment task

Background

Investigating the effects of monetary incentives on dishonest behavior provides valuable insights into human integrity and ethical decision-making processes. This study is conducted through the lens of self-concept maintenance theory.

Aim

The aim of this study is to examine the influence of different types of rewards (score-based vs. monetary) and their magnitude on dishonest behavior within a gender judgment task.

Method

Using a quantitative experimental design, this study involved 116 participants who were randomly assigned to conditions that differed in reward type (score or money) and magnitude (10 yuan vs. 50 yuan). Dishonest behavior was assessed using a gender judgment task with mechanisms to simulate conditions conducive to planned cheating.

Results

Results revealed significant differences in dishonesty rates between score and money conditions, with a higher proportion of dishonest participants observed in the score condition compared to the money condition. The timing of initial cheating was earlier in the score condition compared to the money condition. No significant differences were found in the proportion of dishonest participants, the cheating rate, or the timing of initial cheating across reward levels within either condition. The rate of cheating increased over time, suggesting a temporal dynamic in unethical decision making.

Conclusion

The study demonstrates that the nature of rewards significantly influences the likelihood of dishonest behavior, with intangible score-based rewards facilitating rationalizations for dishonesty more readily than tangible financial incentives. These findings enrich the understanding of moral psychology by highlighting the complex interplay between reward types, ethical rationalization, and the dynamics of dishonest behavior.

The Effect of Socioeconomically Disadvantaged Stereotype Threat on Inhibitory Control in Individuals with Different Household Incomes

Previous studies have discussed the impact of the socioeconomically disadvantaged stereotype threat (SDST) on inhibitory control. But the specific influences of the SDST on inhibitory control in different household income groups are not clear. We hypothesized that the SDST had different effects on inhibitory control in individuals with distinct household income, and the attribution of stimuli would influence it as well, especially the currency value of the stimuli. To investigate it, two studies were conducted, which required inhibiting their motor responses. Specifically, Study 1 explored the influence of the SDST on basic inhibitory control. Study 2 analyzed the influence of the SDST on inhibitory control when the input stimuli included currency values and monetary conception. The results revealed that the inhibitory control ability was worse in the lower income group but not during the processing of stimuli with currency value. For the effect of the SDST, it found that there was a negative effect on those with a lower household income and a positive effect on those with a higher household income. Based on the findings, the effect of the SDST on inhibitory control in human beings is not stable; instead, it varies depending on the traits of the stimuli in different tasks and of the individuals themselves.

The moderation effect of social capital in the relationship between own income, social comparisons and subjective well-being: Evidence from four international datasets

In this paper we check whether social capital changes the association of subjective well-being with own income and social comparisons. We use panel data from Germany and publicly available data from three international surveys, for a total of nearly 500,000 respondents from industrial countries. Results show that the association of own income and social comparisons to subjective well-being weakens for individuals with high social capital. This finding holds in a variety of settings, and is robust to various measures of subjective well-being, of social capital, and of social comparisons. We also find evidence indicating that the role of social capital is, at least in part, causal. Finally, our findings support the macro-level implication that income differences are less related to subjective well-being differences in countries with high social capital.

Boosting attachment security promotes prosociality: The mediating effect of moral disengagement

While attachment security is known to promote prosocial behaviour, a closer examination is needed to clarify the active mechanism in this relationship. We addressed this issue by examining the mediation effect of moral disengagement in two studies. Participants were assigned to the control priming group or the attachment security priming group. After the priming procedure, they completed the measurements of a sense of security, moral disengagement and prosocial behaviour. The results from both studies showed that compared with control priming, attachment security priming enhanced prosociality. Furthermore, mediation analysis showed that moral disengagement mediated the relationship between attachment security and prosociality. The present findings extend the understanding of the underlying mechanisms of attachment security and prosociality, and provide insights into the effectiveness of boosting attachment security in intervening in moral disengagement.

Nostalgic intergroup contact and intergroup relations:Theoretical, empirical, and applied dimensions

Recent research has highlighted the potential of nostalgic recall of intergroup contact as a means of enhancing intergroup relationships and tackling prejudice. In this article, we review the scarce but promising literature that integrates research on nostalgia and intergroup contact. We outline the mechanisms that explain the link between nostalgic intergroup encounters and improved intergroup attitudes and behavior. We further highlight the benefits that nostalgic contact reverie may have for intergroup relations - and beyond. We then discuss the potential of nostalgic intergroup contact as a strategy for real-world, prejudice reduction interventions. Finally, we draw on current research from the fields of nostalgia and intergroup contact to make suggestions for future research. "… nostalgic memories … lead to a vivid sense of commonality [which] accelerates the process of acquaintance in a community where formerly only barriers may have existed." [1, p. 454].

Thinking about neither death nor poverty affects delay discounting, but episodic foresight does: Three replications of the effects of priming on time preferences

We outline three attempts to replicate experiments that reported priming effects on time preferences measured by delay discounting. Experiment 1 tested the claim that images of poverty prime impulsive choice in people from less affluent backgrounds compared with people from more affluent backgrounds. Experiment 2 tested the claim that mortality salience-thinking about death-primes people to place more value on the future than people who thought about dental surgery. Experiment 3 tested the claim that an episodic foresight manipulation primes greater discounting than no episodic foresight. Experiments 1 and 2 failed to replicate the effects of priming on discount rates. Experiment 3 was a successful and very close replication of the effect of episodic foresight on discount rates.

The Dual Effect of Participation Level on Consumer Participation in Participatory CSR: The Role of CSR Fit and Social Support

Corporate social responsibility (CSR) provides companies with two benefits: creating social value and strengthening consumer relationships. Companies implement various types of CSR to maximize the positive effects of CSR, participatory CSR being one of these types. However, although the number of companies using participatory CSR in practice is increasing, academic interest in the effectiveness of participatory CSR has been insufficient. In particular, prior studies on the consumer perception of the participation level presented in participatory CSR do not show clear results. This study examines the influence of the participation level based on CSR fit and social support. The results of this study indicate that when there is a high CSR fit, consumers perceive the participation level as a benefit. However, when the CSR fit is low, consumers perceive the participation level as a cost. Additionally, the results show that the interactive effect of the participation level and CSR fit occurs only when there is less social support. When there is strong social support, consumers perceive the participation level as a benefit regardless of the CSR fit. Finally, the academic and practical implications of the results of this study are presented.

Priming congruence and COVID-19 vaccination intention: a mediation analysis

BACKGROUND

This study took place at the height of the fifth wave of COVID-19 in France, coinciding with stigmatizing communication toward the unvaccinated. We hypothesized that adherence to this communication would facilitate or inhibit the effects of priming on vaccination intention, depending on whether the priming included a dimension of connection to others.

PARTICIPANTS AND PROCEDURE

In a convenience online French sample (N = 1800, M age = 26.30), vaccination intention was asked after love priming, no love/prejudice priming, materialism priming, or a control condition. Participants also reported their adherence to restrictive measures, i.e., media control, vaccination pass, and mandatory vaccination.

RESULTS

Vaccination intention was higher in the no love/prejudice and materialism conditions than in the love and control conditions. Adherence to restrictive measures mediated the effect of prejudice or materialism priming on intention to get vaccinated.

CONCLUSIONS

Implications of these results are discussed in light of the socially situated cognition perspective and the congruence of (a) a societal context of communication toward the vaccine and the unvaccinated, (b) the participant's degree of adherence to that communication, (c) the theme of priming, whether or not related to feeling connected to others. Implications of materialism priming are discussed, and the effect of commitment on intention to get vaccinated.

Typical diet and type of economy do not predict food-sharing behaviors in three Tanzanian societies

Food sharing behavior is a widely observed phenomenon, and it draws attention of scholars interested in finding both proximate and ultimate explanations of such practices. In the current study, we focused on possible socio-economic and environmental food-sharing predictors: type of economy (i.e., immediate-return vs. delayed-return) and typical diet composition (i.e., proportion of proteins and carbohydrates in typical daily caloric intake). We investigated whether members of three societies from Tanzania (N = 177), namely hunter-gatherers (Hadza), pastoralists (Datoga), and agriculturalists (Iraqw) differ with regard to food-sharing patterns in the Dictator Game and reactions to violations of the food-sharing norms in the Ultimatum Game. We found that neither the type of economy nor the typical diet influenced our outcomes. The results indicated, however, that food sharing behavior was positively predicted by certain individual-level characteristics: people of higher strength and lower body fat shared more food, and women were more willing to share food than men.

Nostalgia: An impactful social emotion

Nostalgia (a sentimental longing for one's past) is a highly social emotion. We provide an evidence-based argument that nostalgia's sociality is one of its most defining and impactful characteristics. First, we review evidence that has established the highly social content of nostalgic reflection. Second, we summarize research that has demonstrated nostalgia's capacity to provide a sense of connectedness with others, and that this social connectedness, in turn, conveys intrapersonal psychological benefits (i.e., meaning in life, self-continuity, optimism, inspiration). Third, we outline research that has documented the interpersonal consequences of nostalgia (e.g., greater physical closeness, strengthened relational goals, increased help seeking, intensified empathy, elevated prosocial behavior). Finally, we call for applied research to investigate how the social character of nostalgia can be harnessed to improve people's social lives.

Are monetary gifts negatively labeled? Material benefits and prosocial motivation evaluation

We examined whether people perceive prosocial actors' prosocial motivations differently when prosocial actors gain monetary gifts and goods gifts. Across five studies, 1351 participants read different prosocial scenarios that depicted prosocial actors who gained either monetary or goods gifts. Then, they evaluated the prosocial motivations of the prosocial actors. Studies 1-5 consistently found that people perceived prosocial motivations to be less authentic when prosocial actors chose to receive monetary gifts compared with goods gifts. In addition, moral disgust and moral character evaluation mediated this effect (Studies 3-4). Moreover, the negative effect of monetary gifts on people's perception of prosocial motivation further undermined their helping intention to prosocial actors (Study 5). Our research expanded the understanding of people's perception of material gifts in prosocial behavior by proposing the model of monetary benefits aggravated tainted altruism. Besides, our findings provide insights into public policy and charity rules.

Economic inequality breeds corrupt behaviour

Economists and political scientists have long debated the relations between economic inequality and corruption at the societal level. Extending this literature, we proposed and tested that economic inequality breeds the corrupt behaviour of individuals. Analyses of 45-year archival data from the United States found that official corruption crimes were more prevalent in years and states with greater economic inequality. Three subsequent experiments (N = 776) using economic games showed that individuals exposed to greater economic inequality exhibited more corrupt behaviour in both Chinese and American cultures. Furthermore, the increased desire for wealth and the perception of reduced fairness accounted for this effect. These findings highlight that excessive economic inequality creates a competitive environment in which people give priority to themselves over others and suggest a vicious cycle between economic inequality and corruption.

Behavioral economics: who are the investors with the most sustainable stock happiness, and why? Low aspiration, external control, and country domicile may save your lives—monetary wisdom

Slight absolute changes in the Shanghai Stock Exchange Index (SHSE) corresponded to the city’s immediate increases in coronary heart disease deaths and stroke deaths. Significant fluctuations in the Shenzhen Stock Exchange Index (SZSE) corresponded to the country’s minor, delayed death rates. Investors deal with money, greed, stock volatility, and risky decision-making. Happy people live longer and better. We ask the following question: Who are the investors with the highest and most sustainable stock happiness, and why? Monetary wisdom asserts: Investors apply their deep-rooted values (avaricious love-of-money aspiration and locus of control, Level 2) as a lens to frame critical concerns in the proximal-immediate (Shanghai Stock Exchange Index changes, Level 1) and the omnibus-distal contexts (domicile: city vs. country, Level 2) to maximize expected utility (portfolio changes, Level 1) and ultimate serenity (stock happiness, Level 1). We collected multilevel data—the longitudinal SHSE and 227 private investors’ daily stock happiness and portfolio changes for 36 consecutive trading days in four regions of China. Investors had an average liquid asset of $76,747.41 and $54,660.85 in stocks. This study is not a “one-shot” game with “nothing at stake.” We classified Shanghai and Beijing as the city and Shenzhen and Chongqing as the country. Our cross-level 3-D visualization reveals that regardless of SHSE volatility, investors with low aspiration, external control, and country domicile enjoy the highest and most sustainable stock happiness with minimum fluctuations. Independently, investors with low aspiration, external control, and country domicile tend to make fewer portfolio changes than their counterparts. Behaviorally, less is more, debunking the myth—risky decisions excite stock happiness. Our longitudinal study expands prospect theory, incorporates attitude toward money, and makes robust contributions to behavioral economics and business ethics. We help investors and ordinary citizens make happy, healthy, and wealthy decisions. Most importantly, the life you save may be your own.

The impact of nature video exposure on pro-environmental behavior: An experimental investigation

We analyze whether exposure to a nature documentary increases pro-environmental behavior (PEB). We test this causal link in an experiment where subjects viewed a video featuring either an urban (control treatment) or a nature setting (nature treatment). We consider two types of behavior: a monetary donation to an environmental non-governmental organization (ENGO) that we call an eco-donation, and subsequently, a non-monetary decision (i.e., recycle or not recycle headphone protectors) that we call an eco-action. We find that virtual exposure to nature boosts both eco-donation and eco-action. Interestingly, the increase in PEB only occurs for individuals who express low environmental values. We did not find any negative or positive spillover effects on the eco-action. We finally provide robustness checks and discuss policy implications.

EXPRESS: Market mindset hinders interpersonal trust: The exposure to market relationships makes people trust less through elevated proportional thinking and reduced state empathy

In a series of five experiments, we provided evidence that evoking the market mindset negatively affects trust. We found that the market mindset reduces trust compared to the communal mindset (Experiment 1) and a neutral condition (Experiment 2). Next, we examined the psychological mechanisms behind the detrimental effect of the market mindset on trust and found that this effect was mediated by enhanced proportional thinking (Experiments 3 and 4) and reduced state empathy (Experiments 4 and 5). Finally, in a preregistered Experiment 5, we showed that these two psychological mechanisms are relatively independent.

The Influence of Affective Priming on the Affective Response During Exercise: A Replication Study

The affective response during exercise is an important factor for long-term exercise adherence. Pottratz et al. suggested affective priming as a behavioral intervention for the enhancement of exercise-related affect. The present paper aims to replicate and extend upon these findings. We conducted a close replication with 53 participants completing a brisk walking task in two conditions (prime vs. no prime). Affective valence was assessed during exercise, and exercise enjoyment and remembered/forecasted pleasure were assessed postexercise. We could not replicate the findings of Pottratz et al., finding no evidence for positive changes in psychological responses in the priming condition. However, linear mixed models demonstrated significant interindividual differences in how participants responded to priming. These results demonstrate that affective priming during exercise does not work for everyone under every circumstance and, thus, provide an important contribution to the understanding of boundary conditions and moderating factors for priming in exercise psychology.

I will help you survive but not thrive: Helping decisions in situations that empower women

This research examines gender-based helping behavior from a social dominance perspective. We focused on the interplay between the gender of a prospective donor and the gender of the recipient in shaping donation decisions in contexts that either empower recipients or not. In two studies ( N = 866), male (but not female) donors chose to donate less often (Study 2) and to give lower amounts (Studies 1–2) to women in need than to men when donations were made in a potentially empowering context – a business context (e.g., donating to a person whose shop burned down), than in a nonempowering context – a domestic context (e.g., donating to a person whose house burned down). Lack of empathy for the female recipient among men partially mediated this gender–donation bias effect (Study 2). These findings suggest that men are less likely to help women in situations that empower women and challenge the existing gender hierarchy.

The Influence of Infant Schema Cues on Donation Intention in Charity Promotion

This research performed four experiments to investigate the influence of infant schema cues on charitable donation intention and examine the moderating effect of gender. The results indicate that: (1) individuals stimulated by infant schema (vs. adult schema) cues had a higher willingness to donate when facing charity promotion; (2) the main effect was not due to the perceived cuteness of character in posters; (3) empathy played an entirely mediating role in the relationship between infant schema cues and donation intention; (4) gender moderated the influence of infant schema on donation intention: infant schema cues are effective for improving females’ donation intention, but ineffective for males. These findings contributed to the literature on infant schema and provide practical significance for introducing infant schema in charity promotion.

Impact of Sexual Harassment and Social Support on Burnout in Physician Mothers

Background: Burnout affects >50% of physicians, especially women. This study aimed to examine how negative workplace interactions can predict burnout, and whether positive social interactions can mitigate risk. Materials and Methods: In a study of 1627 physician mothers who responded to a survey by the Physician Moms Group, an online Facebook group, we first examined the association between workplace sexual harassment and burnout. In an embedded experiment, we then measured the causal impact of priming perceived social support and connectedness on the three dimensions of employee burnout. Results: Two-thirds of respondents reported having experienced sexual harassment in the past year. Sexual harassment by patients was associated with 0.27 points higher emotional exhaustion, one dimension of burnout (95% confidence interval [CI] 0.12-0.41), equivalent to the predicted impact of an additional 22 weekly work hours on emotional exhaustion. Sexual harassment by patients was also associated with 0.40 points higher patient depersonalization, another dimension of burnout (95% CI 0.27-0.53). Sexual harassment by colleagues was associated with 0.16 points higher emotional exhaustion (95% CI 0.02-0.30), but not other dimensions of burnout. We found no significant relationship between experiences of sexual harassment and levels of personal accomplishment (the third dimension of burnout) among this sample. Priming physician mothers to reflect on their connectedness with other physician mothers significantly increased their sense of personal accomplishment. The priming intervention did not yield a significant effect on emotional exhaustion or depersonalization. Conclusions: Negative and positive social interactions each affect different dimensions of burnout. Sexual harassment-a pervasive type of negative social interaction-strongly predicts emotional exhaustion and depersonalization. Reflecting on social connectedness-a type of positive social interaction-can improve one's sense of personal accomplishment with an effect similar in magnitude to more intensive in-person interventions, suggesting that social connectedness through online groups merits further consideration as a tool to mitigate burnout.

Materialism Predicts College Students' Entrepreneurial Intention: A Serial Mediation Model

Entrepreneurship is perceived as a critical pillar for unemployment alleviation and economic growth, especially in the era of COVID-19, which highlights the importance of the entrepreneurial potential of college students. The current research focused on the role of personal values in the entrepreneurial process and investigated the relationship between materialism and entrepreneurial intention among college students. Few studies have been examined this relationship, and the underlying mechanisms were also not identified. From the perspective of personal value, we hypothesized that materialism could positively predict entrepreneurial intention. Moreover, based on McClelland's theory of need for achievement and the theory of planned behavior, a serial mediation model, with achievement motivation and entrepreneurial attitude as the mediators, was proposed. We conducted a correlational study on a sample of 1,002 Chinese university students to examine our hypotheses. They participated in an online survey and completed the measurement of entrepreneurial intention, entrepreneurial attitude, materialism, and achievement motivation. The hypothesized models were examined through serial mediation bootstrapping procedures. The results showed that materialism positively predicted college students' entrepreneurial intention, and this relationship was serially mediated through achievement motivation and entrepreneurial attitude. Materialism boosted college students' achievement motivation, which in turn was associated with a more positive entrepreneurial attitude and subsequently stronger entrepreneurial intention. The present research is the first to empirically examine this association's mechanism and establish a serial mediation involving achievement motivation and entrepreneurial attitude. For the theoretical contribution, the present research provides a more comprehensive picture of the role of personal values in entrepreneurship by complementing the effect of materialism. And regarding the practical implications, the present research implies the silver lining of materialism and points out a possible way to enhance college students' entrepreneurial intention, i.e., entrepreneurial education could take advantage of the characteristics of materialism and transform the “harmful” value into socially beneficial entrepreneurial intentions through enhancing their achievement motivation and positive attitude toward entrepreneurship.

The influence of reward anticipation on conflict control in children and adolescents: Evidences from hierarchical drift-diffusion model and event-related potentials

Reward is deemed a performance reinforcer. The current study investigated how social and monetary reward anticipation affected cognitive control in 39 children, 40 adolescents, and 40 adults. We found that cognitive control performance improved with age in a Simon task, and the reaction time (RT) was modulated by the reward magnitude. The conflict monitoring process (target N2 amplitudes) of adolescents and the attentional control processes (target P3 amplitudes) of adolescents and adults could be adjusted by reward magnitude, suggesting that adolescents were more sensitive to rewards compared to children. Reward magnitudes influenced the neural process of attentional control with larger P3 in congruent trails than that in incongruent trials only in low reward condition. The result of hierarchical drift-diffusion model indicated that children had slower drift rates, higher decision threshold, and longer non-decision time than adolescents and adults. Adolescents had faster drift rates in monetary task than in social task under the high reward condition, and they had faster drift rates under high reward condition than no reward condition only in the monetary task. The correlation analysis further showed that adults' non-decision time and decision threshold correlated with conflict monitoring process (N2 responses) and attentional control process on conflicts (P3 responses). Adolescents' drift rates associated with neural process of attentional control. The current study reveals that reward magnitude and reward type can modulate cognitive control process, especially in adolescents.

The Effect of Ostracism on Adults' Materialism: The Roles of Security and Self-Construal

With consumer culture becoming more prominent, the value of materialism is growing rapidly. This study explored the formation of materialism in adults, based on the temporal need–threat model of ostracism and the theory of materialistic values. Specifically, this study examined the link between ostracism and materialism from the perspective of security and the moderating role of self-construal in this process. A sample of 1,272 Chinese adults (M_age = 35.90 ± 11.59, 47.2% male) was recruited to complete the Ostracism Experiences Scale, the Material Values Scale, the Security Questionnaire, and the Self-Construal Scale. The results showed that (1) ostracism positively predicted materialism in Chinese adults; (2) security partially mediated the relationship between ostracism and materialism; (3) and self-construal moderated this mediation model. The moderating effect of self-construal on the relationship between ostracism and security was significant. Specifically, the direct effect of ostracism on security was much stronger for adults with interdependent self-construal than for those with independent self-construal. However, self-construal had no significant moderating effect on the direct effect of ostracism on materialism. These findings suggest that ostracism may affect materialism by damaging adults’ feelings of security, and independent self-construal can buffer the damage of ostracism on security.

Social exclusion modulates neural dynamics of monetary and social reward processing in young adult females

Evidence suggests that social exclusion increases one's sensitivity to monetary and social rewards. However, whether and how social exclusion modulates the neural dynamics of reward processing remains unknown. The current study aimed to address this gap by systematically investigating the differential influences of social exclusion on various stages of monetary and social reward processing. Forty-five female participants were recruited, and the Cyberball game was used to manipulate social exclusion. To disentangle the anticipatory and consummatory stages of monetary and social reward processing, we recorded event-related potentials during two incentive delay tasks, one with a monetary reward and one with a social reward. The results showed that during the anticipatory stage, a larger contingent negative variation was observed for the exclusion group than for the inclusion group, regardless of reward type. During the consummatory stage, although the reward-related positivity was larger in the exclusion group than in the inclusion group, this difference was only observed for the social, and not monetary, reward feedback. These findings advance our understanding of the relationship between social exclusion and reward processing and suggest that while social exclusion might exert comparable enhancement effect for monetary and social reward processing during the anticipatory stage, it exerts a specific enhancement effect for social reward processing during the consummatory stage.

The development of trait greed during young adulthood: A simultaneous investigation of environmental effects and negative core beliefs

Recent models of personality development have emphasized the role of the environment in terms of selection and socialization effects and their interaction. Our study provides partial evidence for these models and, crucially, extends these models by adding a person variable: Core beliefs, which are defined as mental representations of experiences that individuals have while pursuing need-fulfilling goals. Specifically, we report results from a longitudinal investigation of the development of trait greed across time. Based on data from the German Personality Panel, we analyzed data on 1,965 young adults on up to 4 occasions, spanning a period of more than 3 years. According to our results, negative core beliefs that have so far been proposed only in the clinical literature (e.g., being unloved or being insecure) contributed to the development of trait greed, indicating that striving for material goals might be a substitute for unmet needs in the past. Additionally, greedy individuals more often self-selected themselves into business-related environments, which presumably allow them to fulfill their greed-related need to earn a lot of money. Our results expose important mechanisms for trait greed development. Regarding personality development in general, core beliefs were identified as an important variable for future theory building.

Money priming and children’s self-evaluations

Previous studies have shown that money priming changes adults’ behavior and self-esteem, making them become more congruent with market mode. Money priming has also been seen to change behavior in children who have yet develop a complete understanding of its instrumental functions. Since money’s association with markets changes people’s behavior even in childhood, it is possible that its links and ties to self-esteem are forged at an early stage in life. The studies presented in this article aimed to verify how money priming affects various types of self-evaluations made by children. Two experimental studies were conducted. A total of 83 children aged 8–10 years took part in the first study, while 103 children aged 4–6 years took part in the second study. The results demonstrate that priming with money may change some, but not all, of children’s self-evaluations. Subsequent to money priming, children’s self-evaluations became more congruent with market mode: under the influence of money priming, children’s self-evaluations increased in domains involving perceived competences (associated with feelings of agency), but did not increase in domains related to social relationships.

Bias correction for eta squared in one-way ANOVA

Eta squared is a popular effect size, but contains positive bias. Bootstrapping can be used to remove the bias from eta squared. Compared to epsilon squared and omega squared, bootstrap bias correction does not make distributional assumption, and it is easy to implement. A real example and computer simulations are included to illustrate its application. The bootstrap bias-corrected eta squared shows very little bias, and it serves as a good alternative to eta squared and epsilon squared, the latter of which can turn negative in some circumstances.

Internet Use and Quality of Life: The Multiple Mediating Effects of Risk Perception and Internet Addiction

The impact of internet use on quality of life (QoL) has become an increasing focus of academic research. This paper aims to explore the internal influencing mechanisms of internet use (i.e., leisure-oriented internet use (LIU); work-oriented internet use (WIU)) on QoL, with a focus on the multiple mediating effects of risk perception and internet addiction. We constructed a theoretical framework from a psychological perspective and tested the hypotheses using hierarchical regression analysis with a sample of 1535 participants. The results showed that: (1) LIU had a positive effect on QoL, while WIU did not have a significant impact on QoL; (2) both risk perception and internet addiction had a negative influence on QoL; (3) risk perception positively impacted internet addiction; (4) risk perception and internet addiction had multiple mediating effects on the relationship between internet use and QoL.

Global evidence on the selfish rich inequality hypothesis

People’s beliefs about why the rich are richer than the poor have the potential to affect both policy attitudes and economic development. We provide global evidence showing that where the fortunes of the rich are perceived to be the result of selfish behavior, inequality is viewed as unfair, and there is stronger support for income redistribution. However, we also observe that belief in selfish rich inequality is highly polarized in many countries and thus a source of political disagreement that might be detrimental to economic development. We find systematic country differences in the extent to which people believe that selfishness is a source of inequality, which sheds light on international differences in public morality, civic virtues, and redistributive policies.

We report on a study of whether people believe that the rich are richer than the poor because they have been more selfish in life, using data from more than 26,000 individuals in 60 countries. The findings show a strong belief in the selfish rich inequality hypothesis at the global level; in the majority of countries, the mode is to strongly agree with it. However, we also identify important between- and within-country variation. We find that the belief in selfish rich inequality is much stronger in countries with extensive corruption and weak institutions and less strong among people who are higher in the income distribution in their society. Finally, we show that the belief in selfish rich inequality is predictive of people’s policy views on inequality and redistribution: It is significantly positively associated with agreeing that inequality in their country is unfair, and it is significantly positively associated with agreeing that the government should aim to reduce inequality. These relationships are highly significant both across and within countries and robust to including country-level or individual-level controls and using Lasso-selected regressors. Thus, the data provide compelling evidence of people believing that the rich are richer because they have been more selfish in life and perceiving selfish behavior as creating unfair inequality and justifying equalizing policies.

Exposure to money modulates the processing of charitable donation: An event-related potentials study

Exposure to monetary cues might affect charitable donations, but little is known about how monetary cues affect charitable donations from the neural perspective. The present study examined the effect of monetary cues on charitable donations by means of event-related potentials (ERPs). Participants primed with monetary or neutral images decided whether to accept donation offers with the high, moderate, and low costs. The behavioural results showed that in the money-primed condition, participants took more time to decide for the high-cost than for the moderate and low-cost donation offers. The ERP results showed that the P2 and P3 were larger in the money-primed condition relative to the neutral images condition. Notably, participants primed with money demonstrated larger P3 for the high-cost donation offers than for the moderate and low-cost offers, but this difference was not observed in the control condition. These findings indicate that people primed with money may pay more attention to the cost-relevant information related to their self-interests when conducting prosocial behaviours.

Synaptic dysfunction of Aldh1a1 neurons in the ventral tegmental area causes impulsive behaviors

Background

Aldh1a1 neurons are a subtype of gamma-aminobutyric acid (GABA) inhibitory neurons that use Aldh1a1 rather than glutamate decarboxylase (GAD) as an enzyme for synthesizing GABA transmitters. However, the behaviors and circuits of this newly identified subtype of inhibitory interneurons remain unknown.

Methods

We generated a mutant mouse line in which cyclization recombination enzyme (CRE) was expressed under the control of the Aldh1a1 promotor (Aldh1a1-CRE mice). Using this mutant strain of mice together with the heterozygous male Alzheimer’s disease (AD) related model mice (APPswe/PSEN1dE9, or AD mice) and a genetically modified retrograde and anterograde synaptic tracing strategy, we have studied a specific synaptic circuit of Aldh1a1 neurons with system-level function and disease progression in AD mice.

Results

We demonstrate that Aldh1a1 neurons encode delay of gratification that measures self-control skills in decision making by projecting inhibitory synapses directly onto excitatory glutamate neurons in the intermediate lateral septum (EGNIS) and receiving synaptic inputs from layer 5b pyramidal neurons in the medial prefrontal cortex (L5PN). L5PN → Aldh1a1 synaptic transmission undergoes long-term potentiation (LTP). Pathway specific inhibition by either genetic silencing presynaptic terminals or antagonizing postsynaptic receptors impairs delay of gratification, resulting in the impulsive behaviors. Further studies show that reconstitution of Aldh1a1-deficient neurons with the expression of exogenous Aldh1a1 (eAldh1a1) restores Aldh1a1 → EGNIS synaptic transmission and rescues the impulsive behaviors in AD mice.

Conclusions

These results not only identify a specific function and circuit of Aldh1a1 neurons but also provide a cellular point of entry to an important but understudied synaptic mechanism for the induction of impulsive behaviors at an early stage of AD.

Publication bias and low power in field studies on goal priming

Research on goal priming asks whether the subtle activation of an achievement goal can improve task performance. Studies in this domain employ a range of priming methods, such as surreptitiously displaying a photograph of an athlete winning a race, and a range of dependent variables including measures of creativity and workplace performance. Chen, Latham, Piccolo and Itzchakov (Chen et al. 2021 J. Appl. Psychol. 70, 216-253) recently undertook a meta-analysis of this research and reported positive overall effects in both laboratory and field studies, with field studies yielding a moderate-to-large effect that was significantly larger than that obtained in laboratory experiments. We highlight a number of issues with Chen et al.'s selection of field studies and then report a new meta-analysis (k = 13, N = 683) that corrects these. The new meta-analysis reveals suggestive evidence of publication bias and low power in goal priming field studies. We conclude that the available evidence falls short of demonstrating goal priming effects in the workplace, and offer proposals for how future research can provide stronger tests.

Psychological Oneness: A Typology

Oneness is a sense of profound unity with some other entity, typically a large, abstract entity such as nature or all of existence. This article offers a typology of oneness based on a review of oneness concepts in the psychology literature. The typology distinguishes between oneness experiences and oneness intuitions or beliefs, the latter being propositions about how self and other are connected. It also distinguishes between three perceived ontologies: expansion (including other in self), interdependence (self and other in symbiosis), and essential (self and other sharing some fundamental property). Confirmatory factor analysis ( n = 102) supported the typology’s dimensions within the scope of nature, using novel sets of items based on restructuring extant oneness measures. Implications of the typology for understanding oneness with nature and its role in addressing environmental crises are discussed, including how these may interact with cultural context.

Social status affects how third parties assess unfairly shared losses and unfairly shared gains

The present paper focused on how a third party's social status affects third-party intervention to maintain social fairness. Study 1 adopted a quasi-experimental design. Selecting high and low-status members of real social groups, we observed that high-status individuals intervened more forcibly and more frequently when assessing the fairness of players' behavior in a dictator game (DG). The manifestation of social status is generally divided into power and economic capital. In Study 2a, using the same DG punishment-compensation paradigm we randomly assigned the third party in the lab to high, medium, and low impact conditions, where their actions had relative multiplier effects on the resources retained by dictators and recipients. This tested whether the power to influence the situation would systematically affect third party's behavior. We found that greater influence predicted increased interventions. Study 2b investigated the influence of economic capital or intrinsic wealth on a third party's altruistic behavior by varying how much capital the third party had at their disposal to spend on punishment or recompensing. Having high capital predicted an increase in the size of penalty inflicted or compensation offered, but resource abundance had no effect on the likelihood that the third party would intervene. In conclusion, the paper showed that the social status of the third party truly does affect their altruistic interventions and the impact of social status on altruistic behaviors for maintaining fairness by the third party occurred primarily through the third parties' perception of their power. Furthermore, the influence of gain and loss contexts and social status on third-party punishment and compensation were independent of each other. This paper provided a new perspective for third-party altruistic behaviors and help to clarify the view of social fairness.

Who cares about ethical practices at workplace? A taxonomy of employees’ unethical conduct from top management perspective

Purpose

The purpose of the study is to explore the various kind of prevailing unethical practices at workplace along with identification of factors triggering such unethical practices. Growing incidences of indulgence of employees in unethical acts in various organisation and negative consequences associated with it for the organisation such as erosion of reputation because of advance digital media coverage, shareholder value and others made compulsive to study the root cause of unethical behaviour at the workplace.

Design/methodology/approach

This study extracts meaning from the experiences of top managers working in nine Indian organisations to understand the challenges faced by individuals at the workplace using the Gioia methodology. A total of 33 top management team (TMT) members were interviewed in detail to capture their experience in regard to various challenges that impose a threat to ethical conduct in the organisation.

Findings

The authors identified four categories of unethical behaviour, namely, pro-self, lack of autonomy, pro-organisation, systemic and negligence. Further, the authors have developed a taxonomy suggesting strategies to control unethical conduct at the workplace. Besides, the current study unravels the triggers behind different categories of unethical conduct, such as bottom-line mentality, rent-seeking behaviour of government officials, fluid ethical study culture and others.

Originality/value

Various types of unethical behaviour have been identified and frameworks to address such unethical practices are suggested in the paper. TMTs views have been captured to understand the root cause of unethical practices and strategies for addressing them have been discussed in the paper.
