Subjective experiences of resource scarcity can make individuals short‐term oriented, capture attention, and trigger feelings of unfairness. However, the impact of scarcity on information processing and ethical decision‐making remains poorly understood. This eye‐tracking study explored how acute financial scarcity affects selective information search and ethical decision‐making in an economic task with competing incentives (N = 60, 12,000 observations). Results revealed that participants experiencing financial scarcity displayed a strong attentional bias towards financially tempting information, although they ultimately did not behave more unethically. These findings might reveal a "moral boundary" dictating when attentional biases translate into decision‐making. Our results contribute to understanding how individuals in scarcity contexts process and prioritize information in ethical decision‐making, helping organizations and policymakers combat stereotypes surrounding resource‐deprived individuals, and design evidence‐based policy interventions promoting ethical behavior in financially scarce situations.

This document is a response to a previous article about experiment aversion. The authors conducted tests and found that experiment aversion is not a general tendency but rather specific to certain contexts. They also addressed factual errors and unsubstantiated claims made by the previous authors. The text includes various studies and disagreements with other researchers. More context is needed to provide a concise and accurate summary. [Extracted from the article]

What facilitates collaborative cheating in hierarchical teams, and what are its outcomes for those engaged? In two preregistered studies (N = 724), we investigated how subordinates are influenced by leaders signaling a willingness to engage in collaborative cheating, and how subordinates perceive such leaders. Participants performed a task in which they could either report their performance honestly, or cheat for financial gain. Each participant was assigned a leader who could choose to check the report's veracity. In Study 1, leaders who checked less often were perceived as more moral, trustworthy, competent, and psychologically closer than leaders who checked more often. This trustworthiness bonus translated to investments in a subsequent trust game. Study 2 revealed that these relationship benefits specifically arise for collaborative cheating, compared to competitive cheating (at the leader's expense). We conclude that collaborative cheating in subordinate–leader dyads strengthens in-group bonds, bringing people closer together and cultivating trust. [ABSTRACT FROM AUTHOR]

Over the past decade, governments and organizations around the world have established behavioral insights teams advocating for randomized experiments. However, recent findings by M. N. Meyer et al., Proc. Natl. Acad. Sci. U.S.A. 116, 10723–10728 (2019) and P. R. Heck, C. F. Chabris, D. J. Watts, M. N. Meyer, Proc. Natl. Acad. Sci. U.S.A. 117, 18948–18950 (2020) suggest that people often rate randomized experiments as less appropriate than the policies they contain even when approving the implementation of either policy untested and when none of the individual policies is clearly superior. The authors warn that this could cause policymakers to avoid running large-scale field experiments or being transparent about running them and might contribute to an adverse heterogeneity bias in terms of who is participating in experiments. In one direct and six conceptual preregistered replications (total N = 5,200) of the previously published larger-effect studies, using the same main dependent variable but with variations in scenario wordings, recruitment platforms, and countries, and the addition of further measures to assess people’s views, we test the generalizability and robustness of these findings. Together, we find that the original results do not appear to generalize. That is, our triangulation reveals insufficient evidence to conclude that people exhibit a common pattern of behavior that would be consistent with relative experiment aversion, thereby supporting recent findings by R. Mislavsky, B. Dietvorst, U. Simonsohn, Mark. Sci. 39, 1092–1104 (2020). Thus, policymakers may not need to be concerned about employing evidence-based practices more so than about universally implementing policies. [ABSTRACT FROM AUTHOR]

Innovative technologies often feature inherently conflicting properties. This poses a challenge for marketers because negative properties not only weigh heavily on consumers' technology adoption decisions but potentially do more so than positive ones. To shed light on the paradox of technology and its underlying processes, the present research develops a conceptual model drawing on technology adoption and valence perception theories about the prevalence of negativity bias in consumers' technology adoption decisions with its unique effect through the serial chain of consumers' perceptions of risk and trust regarding the technology. Results of three studies (N = 1309) demonstrate that the effect of negative valence consistently outperforms that of positive valence in consumers' technology adoption intentions (Studies 1–2) and decisions (Study 3). Furthermore, results show that the disproportionate effect of negative (vs. positive) valence can be explained by the proposed serial causal chain through consumers' perception of risk of the technology and trust in the technology (Studies 2–3) while ruling out company trust and consumer knowledge as alternative drivers of the effects (Study 3). These findings contribute to the pertinent literature on consumer psychology in decisions to adopt novel technologies in that they quantify and explain the potential outcome stemming from the ambiguous properties of novel technology. Moreover, this study finds negativity bias to be an often overlooked consumer bias with implications for marketing practice and useful for understanding and lowering resistance towards artificial intelligence technology.

The model of ownership psychology as a cognitive adaptation proposes that people flexibly navigate cognitive systems of cooperation and competition, thus enabling them to justify unethical behavior. We discuss how this model captures previous accounts of unethical behavior and propose that a disengagement heuristic can help us understand recent findings in the interconnection between scarcity psychology and unethical behavior.

Believing in conspiracy theories is a major problem, especially in the face of a pandemic, as these constitute a significant obstacle to public health policies, like the use of masks and vaccination. Indeed, during the COVID-19 pandemic, several ungrounded explanations regarding the origin of the virus or the effects of vaccinations have been rising, leading to vaccination hesitancy or refusal which poses as a threat to public health. Recent studies have shown that in the core of conspiracy theories lies a moral evaluation component; one that triggers a moral reasoning which reinforces the conspiracy itself. To gain a better understanding of how conspiracy beliefs about COVID-19 affect public health containment behaviors and policy support via morality-relevant variables, we analysed comprehensive data from the International Collaboration on the Social & Moral Psychology (ICSMP) of COVID-19, consisting of 49.965 participants across 67 countries. We particularly explored the mediating role of two levels of morality: individual and group-based morality. Results show that believing in conspiracy theories reduces adoption of containment health-related behaviors and policy support of public health measures, but moral identity and morality-as-cooperation significantly mediate this relationship. This means that beliefs in conspiracy theories do not simply constitute antecedents of cognitive biases or failures, nor maladaptive behaviors based on personality traits, but are morally infused and should be dealt as such. Based on our findings, we further discuss the psychological, moral, and political implications of endorsement of conspiracy theories in the era of the pandemic. [ABSTRACT FROM AUTHOR]

The COVID-19 pandemic continues to impact people worldwide–steadily depleting scarce resources in healthcare. Medical Artificial Intelligence (AI) promises a much-needed relief but only if the technology gets adopted at scale. The present research investigates people's intention to adopt medical AI as well as the drivers of this adoption in a representative study of two European countries (Denmark and France, N = 1068) during the initial phase of the COVID-19 pandemic. Results reveal AI aversion; only 1 of 10 individuals choose medical AI over human physicians in a hypothetical triage-phase of COVID-19 pre-hospital entrance. Key predictors of medical AI adoption are people's trust in medical AI and, to a lesser extent, the trait of open-mindedness. More importantly, our results reveal that mistrust and perceived uniqueness neglect from human physicians, as well as a lack of social belonging significantly increase people's medical AI adoption. These results suggest that for medical AI to be widely adopted, people may need to express less confidence in human physicians and to even feel disconnected from humanity. We discuss the social implications of these findings and propose that successful medical AI adoption policy should focus on trust building measures–without eroding trust in human physicians.

When medicines enter the environment, they harm living species and ecosystems. Improper disposal of household pharmaceutical waste increases the concentration of pharmaceuticals in the environment and thus their detrimental impacts. Since 2004, the EU has obliged its Member States to establish 'an appropriate collection system' for unused and/or expired medication. However, as no implementation guidelines exist, large differences in the systems and their use remain. Pressure for adoption of guidelines harmonising the systems across the EU has been increasing. We address the question whether such harmonisation could mitigate pharmaceutical pollution, and which regulatory measures would be appropriate. To answer this, we conduct a comparative investigation of the systems' regulation and an empirical study of citizens' beliefs and behaviour across four European countries. We find a potential for increasing the effectiveness of pharmaceutical take-back systems through their harmonisation and conclude that the EU has the competence and tools to regulate this.

It is widely assumed that mindfulness training will lead to a range of benefits, from improved attentional capacities to better decision-making. Indeed, many large corporations have begun to provide workplace mindfulness training with the aim of improving group-based decision-making. Yet, there has been little empirical work testing the effects of mindfulness training on complex group-based task performance. In a randomised experimental study (N = 332), we examine the effects of two different durations of mindfulness training on strategic decision-making using the classic NASA survival task, assessing individual and then group performance. We expected that a longer training duration (seven daily sessions) would be associated with better group performance relative to a "one-off" training session. We did not find such an association: groups in the longer training condition made slightly, but not significantly, more errors than groups in the one-off condition. We did not find any differences across training conditions when examining individual performance. Our findings should be interpreted in light of numerous studies demonstrating the benefits of even short durations of mindfulness practice on cognitive performance. We conclude that our lengthier mindfulness training duration did not confer measurable benefits over a one-off training session at either the individual or the group level on a strategic decision-making task.

Pharmaceutical science has provided humans with better and cheaper treatments. However, with improved access to medicines, the amount of pharmaceutical waste also grows. Pharmaceutical waste is regularly mismanaged by households, which is considerably and unnecessarily adding to the "pharmaceuticals in the environment" problem. Redesigning existing pharmaceutical takeback schemes and their regulation is a potential step towards a reduction of the problem. Interdisciplinary research between the fields of psychology, law, public health and medical science is necessary to tackle the issue and to design effective regulation steering responsible patient behaviours.

Virtual immersive training (VIT) systems based on gamification of tasks are increasingly employed to train assembly workers. In this article, we present a study that compares the effectiveness of virtual and physical training for teaching a bimanual assembly task and in a novel approach, we introduce task complexity (T$_{\mathrm{CXB}}$ CXB) as an indicator of assembly errors during final assembly. In a between-subjects experiment, 100 participants were trained to assemble a 3-D cube in one of the four conditions (physical, virtual and with trainer's verbal assistance or not). The results demonstrate that the best-performing conditions, both in terms of successful assemblies and time performance, are the ones that the physical objects are included in the training, whereas no significant difference is found when the trainer's verbal assistance is present or absent during training. Additionally, we address the validity of a practical T$_{\mathrm{CXB}}$ CXB list as a tool for supporting the design of VIT systems. [ABSTRACT FROM AUTHOR]

Although scientists agree that replications are critical to the debate on the validity of religious priming research, religious priming replications are scarce. This paper attempts to replicate and extend previously observed effects of religious priming on ethical behavior. We test the effect of religious instrumental music on individuals' ethical behavior with university participants (N = 408) in the Czech Republic, Japan, and the US. Participants were randomly assigned to listen to one of three musical tracks (religious, secular, or white noise) or to no music (control) for the duration of a decision-making game. Participants were asked to indicate which side of a vertically-bisected computer screen contained more dots and, in every trial, indicating that the right side of the screen had more dots earned participants the most money (irrespective of the number of dots). Therefore, participants were able to report dishonestly to earn more money. In agreement with previous research, we did not observe any main effects of condition. However, we were unable to replicate a moderating effect of self-reported religiosity on the effects of religious music on ethical behavior. Nevertheless, further analyses revealed moderating effects for ritual participation and declared religious affiliation congruent with the musical prime. That is, participants affiliated with a religious organization and taking part in rituals cheated significantly less than their peers when listening to religious music. We also observed significant differences in cheating behavior across samples. On average, US participants cheated the most and Czech participants cheated the least. We conclude that normative conduct is, in part, learned through active membership in religious communities and our findings provide further support for religious music as a subtle, moral cue.

Background/Objectives: Sharing the bed with a partner is common among adults and impacts sleep quality with potential implications for mental health. However, hitherto findings are contradictory and particularly polysomnographic data on co-sleeping couples are extremely rare. The present study aimed to investigate the effects of a bed partner's presence on individual and dyadic sleep neurophysiology. Methods: Young healthy heterosexual couples underwent sleep-lab-based polysomnography of two sleeping arrangements: individual sleep and co-sleep. Individual and dyadic sleep parameters (i.e., synchronization of sleep stages) were collected. The latter were assessed using cross-recurrence quantification analysis. Additionally, subjective sleep quality, relationship characteristics, and chronotype were monitored. Data were analyzed comparing co-sleep vs. individual sleep. Interaction effects of the sleeping arrangement with gender, chronotype, or relationship characteristics were moreover tested. Results: As compared to sleeping individually, co-sleeping was associated with about 10% more REM sleep, less fragmented REM sleep (p = 0.008), longer undisturbed REM fragments (p = 0.0006), and more limb movements (p = 0.007). None of the other sleep stages was significantly altered. Social support interacted with sleeping arrangement in a way that individuals with suboptimal social support showed the biggest impact of the sleeping arrangement on REM sleep. Sleep architectures were more synchronized between partners during co-sleep (p = 0.005) even if wake phases were excluded (p = 0.022). Moreover, sleep architectures are significantly coupled across a lag of ± 5min. Depth of relationship represented an additional significant main effect regarding synchronization, reflecting a positive association between the two. Neither REM sleep nor synchronization was influenced by gender, chronotype, or other relationship characteristics. Conclusion: Depending on the sleeping arrangement, couple's sleep architecture and synchronization show alterations that are modified by relationship characteristics. We discuss that these alterations could be part of a self-enhancing feedback loop of REM sleep and sociality and a mechanism through which sociality prevents mental illness. [ABSTRACT FROM AUTHOR]

This article analyses contractual governance practices within the value chains of large companies based in the USA and Europe between 2012 and 2017 with focus on human and labour rights. In line with the existing scholarship, we find that the use of contractual governance for safeguarding human and labour rights is best practice among large American and European businesses. The results show that value chain contractual governance should be studied in an interdisciplinary environment taking both legal and non-legal aspects into consideration. Moreover, we detect a general positive impact of the business and human rights regulatory wave of 2010–2011 on sustainable contractual governance practices. [ABSTRACT FROM AUTHOR]

Objective: The present study explores the relationship between neuroactive hormones and religious commitment. We hypothesised that religious commitment is mediated by neuropeptide Y and oxytocin. These neurohormones have a well-established role in general well-being, anxiety regulation, stress-resilience, social affiliation and spirituality. Methods: Sixty healthy women (median age 21) participated in the study and completed the Religious Commitment Inventory and other psychometric surveys. Blood was sampled from each participant and serum levels of neuropeptide Y were measured using radioimmunoassay. Oxytocin, stress and sex hormones were measured using enzyme-linked immunosorbent assay. Correlations were tested using non-parametric statistical methods. Results: We found a positive correlation between serum neuropeptide Y levels and religious commitment, but not between oxytocin and religious commitment. Conclusions: The present study provides preliminary evidence that neuropeptide Y is a biological correlate of religious commitment. [ABSTRACT FROM AUTHOR]

The present study aimed to explore dynamic and interactive aspects of cosleep in heterosexual couples. The sample consisted of eight young healthy adults who belonged to four heterosexual couples with a good relationship quality and a history of cosleeping. All individuals underwent simultaneous polysomnography in a sleep laboratory for four nights in which they slept individually and with their partner. Also, a sleep protocol of subjective sleep measures was completed. Statistical analyses included cross recurrence quantification analysis to assess synchronization during sleep. Cosleeping was associated with better subjective sleep quality, increased total sleep time, sleep efficiency, total slow wave sleep, and REM sleep. Sleep stages were more synchronized during cosleep independent of awakenings. Cardiorespiratory measures remained unchanged. The results indicate that young healthy couples in good relationships benefit from cosleeping on a subjective and objective level. Combining simultaneous polysomnography and cross recurrence quantification analysis is a promising method to study dynamic and interactive aspects of cosleep possibly leading to deeper understanding of the role of sleep for sociality, the nature of REM sleep, and the partner as a social zeitgeber. Moreover, clinical implications may arise from these findings. [ABSTRACT FROM AUTHOR]

A variety of joint action studies show that people tend to fall into synchronous behavior with others participating in the same task, and that such synchronization is beneficial, leading to greater rapport, satisfaction, and performance. It has been noted that many of these task environments require simple interactions that involve little planning of action coordination toward a shared goal. The present study utilized a complex joint construction task in which dyads were instructed to build model cars while their hand movements and heart rates were measured. Participants built these models under varying conditions, delimiting how freely they could divide labor during a build session. While hand movement synchrony was sensitive to the different tasks and outcomes, the heart rate measure did not show any effects of interpersonal synchrony. Results for hand movements show that the more participants were constrained by a particular building strategy, the greater their behavioral synchrony. Within the different conditions, the degree of synchrony was predictive of subjective satisfaction and objective product outcomes. However, in contrast to many previous findings, synchrony was negatively associated with superior products, and, depending on the constraints on the interaction, positively or negatively correlated with higher subjective satisfaction. These results show that the task context critically shapes the role of synchronization during joint action, and that in more complex tasks, not synchronization of behavior, but rather complementary types of behavior may be associated with superior task outcomes.

Priming with religious concepts is known to have a positive effect on prosocial behavior; however, the effects of religious primes associated with outgroups remain unknown. To explore this, we conducted a field experiment in a multicultural, multireligious setting (the island of Mauritius). Our design used naturally occurring, ecologically relevant contextual primes pertinent to everyday religious and secular life while maintaining full experimental control. We found that both ingroup and outgroup religious contexts increased generosity as measured by a donation task. In accordance with previous research, we also found an interaction between individual religiosity and the efficacy of the religious primes. We discuss these findings and their interpretation, and we suggest potential avenues for further research. [ABSTRACT FROM AUTHOR]

Music is a natural human expression present in all cultures, but the functions it serves are still debated. Previous research indicates that rhythm, an essential feature of music, can enhance coordination of movement and increase social bonding. However, the prolonged effects of rhythm have not yet been investigated. In this study, pairs of participants were exposed to one of three kinds of auditory stimuli (rhythmic, arrhythmic, or white-noise) and subsequently engaged in five trials of a joint-action task demanding interpersonal coordination. We show that when compared with the other two stimuli, exposure to the rhythmic beat reduced the practice effect in task performance. Analysis of the behavioral data suggests that this reduction results from more temporally coupled motor movements over successive trials and that shared exposure to rhythm facilitates interpersonal motor coupling, which in this context serves to impede the attainment of necessary dynamic coordination. We propose that rhythm has the potential to enhance interpersonal motor coupling, which might serve as a mechanism behind its facilitation of positive social attitudes. [ABSTRACT FROM AUTHOR]

Religion can have an important influence in moral decision-making, and religious reminders may deter people from unethical behavior. Previous research indicated that religious contexts may increase prosocial behavior and reduce cheating. However, the perceptual-behavioral link between religious contexts and decision-making lacks thorough scientific understanding. This study adds to the current literature by testing the effects of purely audial religious symbols (instrumental music) on moral behavior across three different sites: Mauritius, the Czech Republic, and the USA. Participants were exposed to one of three kinds of auditory stimuli (religious, secular, or white noise), and subsequently were given a chance to dishonestly report on solved mathematical equations in order to increase their monetary reward. The results showed cross-cultural differences in the effects of religious music on moral behavior, as well as a significant interaction between condition and religiosity across all sites, suggesting that religious participants were more influenced by the auditory religious stimuli than non-religious participants. We propose that religious music can function as a subtle cue associated with moral standards via cultural socialization and ritual participation. Such associative learning can charge music with specific meanings and create sacred cues that influence normative behavior. Our findings provide preliminary support for this view, which we hope further research will investigate more closely. [ABSTRACT FROM AUTHOR]

Laboratory and field studies have demonstrated that exposure to cues of intentional agents in the form of eyes can increase prosocial behavior. However, previous research mostly used 2-dimensional depictions as experimental stimuli. Thus far no study has examined the influence of the spatial properties of agency cues on this prosocial effect. To investigate the role of dimensionality of agency cues on fairness, 345 participants engaged in a decision-making task in a naturalistic setting. The experimental treatment included a 3-dimensional pseudo-realistic model of a human head and a 2-dimensional picture of the same object. The control stimuli consisted of a real plant and its 2-D image. Our results partly support the findings of previous studies that cues of intentional agents increase prosocial behavior. However, this effect was only found for the 3-D cues, suggesting that dimensionality is a critical variable in triggering these effects in a real-world settings. Our research sheds light on a hitherto unexplored aspect of the effects of environmental cues and their morphological properties on decision-making. [ABSTRACT FROM AUTHOR]

The physiological processes underlying trust are subject of intense interest in the behavioral sciences. However, very little is known about how trust modulates the affective link between individuals. We show here that trust has an effect on heart rate arousal and synchrony, a result consistent with research on joint action and experimental economics. We engaged participants in a series of joint action tasks which, for one group of participants, was interleaved with a PGG, and measured their heart synchrony and arousal. We found that the introduction of the economic game shifted participants' attention to the dynamics of the interaction. This was followed by increased arousal and synchrony of heart rate profiles. Also, the degree of heart rate synchrony was predictive of participants' expectations regarding their partners in the economic game. We conclude that the above changes in physiology and behavior are shaped by the valuation of other people's social behavior, and ultimately indicate trust building process. [ABSTRACT FROM AUTHOR]

How do people feel during extreme collective rituals? Despite longstanding speculation, few studies have attempted to quantify ritual experiences. Using a novel pre/post design, we quantified physiological fluctuations (heart rates) and self-reported affective states from a collective fire-walking ritual in a Mauritian Hindu community. Specifically, we compared changes in levels of happiness, fatigue, and heart rate reactivity among high-ordeal participants (fire-walkers), low-ordeal participants (non-fire-walking participants with familial bonds to fire-walkers) and spectators (unrelated/unknown to the fire-walkers). We observed that fire-walkers experienced the highest increase in heart rate and reported greater happiness post-ritual compared to low-ordeal participants and spectators. Low-ordeal participants reported increased fatigue after the ritual compared to both fire-walkers and spectators, suggesting empathetic identification effects. Thus, witnessing the ritualistic suffering of loved ones may be more exhausting than experiencing suffering oneself. The findings demonstrate that the level of ritual involvement is important for shaping affective responses to collective rituals. Enduring a ritual ordeal is associated with greater happiness, whereas observing a loved-one endure a ritual ordeal is associated with greater fatigue post-ritual. [ABSTRACT FROM AUTHOR]
