The watching eyes effect has gained significant attention in recent years both from scientists and from policy makers and professionals in the field. The phenomenon posits that the mere presence of eye cues can promote prosocial behavior. However, there is a growing debate about the generality of the effect across various measures and contexts. This review seeks to combine various distinct -and formerly isolated- perspectives by identifying four key components for effective interventions based on the watching eyes effect: Anonymity, crowdedness, costs, and exposure. Eye cues need to reduce perceived anonymity, be placed in non-crowded places, target low-cost prosocial acts and appear for a short amount of time. Next to these conditions, we discuss implications for other cues to reputation and recommend directions that will stimulate further research and applications in society. [ABSTRACT FROM AUTHOR]

People cooperate every day in ways that range from largescale contributions that mitigate climate change to simple actions such as leaving another individual with choice – known as social mindfulness. It is not yet clear whether and how these complex and more simple forms of cooperation relate. Prior work has found that countries with individuals who made more socially mindful choices were linked to a higher country environmental performance – a proxy for complex cooperation. Here we replicated this initial finding in 41 samples around the world, demonstrating the robustness of the association between social mindfulness and environmental performance, and substantially built on it to show this relationship extended to a wide range of complex cooperative indices, tied closely to many current societal issues. We found that greater social mindfulness expressed by an individual was related to living in countries with more social capital, more community participation and reduced prejudice towards immigrants. Our findings speak to the symbiotic relationship between simple and more complex forms of cooperation in societies. [ABSTRACT FROM AUTHOR]

We aimed to investigate the role of moral value in influencing cooperative behavior in environmental conservation. Our research involved two studies examining whether attributing moral value to non-sentient resources (the environment) impacts participants’ resource preservation actions. Results revealed that associating an environmental consequence with resource consumption led to increased cooperative behavior, driven by a desire to protect trees and nature’s intrinsic value. Further, participants demonstrated higher conservation efforts when the environmental consequence was paired with a beautiful image of a tree. These findings suggest that the beauty of nature may be a significant driver of cooperation. The results of these studies shed light on the non-monetary value that people place on resources. Beauty and the inherent value of nature may be critical for our understanding of environmental conservation, emphasizing the potential of moral and aesthetic appreciation as key drivers of pro-environmental actions.

People are quick to form impressions of others' social class, and likely adjust their behavior accordingly. If social class is linked to prosociality, as literature suggests, then an interaction partner's class should affect prosocial behavior, especially when costs or investments are low. We test this expectation using social mindfulness (SoMi) and dictator games (DG) as complementary measures of prosociality. We manipulate target class by providing information regarding a target's (a) position on a social class ladder, and (b) family background. Three studies using laboratory and online approaches (N overall = 557) in two nations (the Netherlands [NL], the UK), featuring actual and hypothetical exchanges, reveal that lower class targets are met with greater prosociality than higher class targets, even when based on information about the targets' parents (Study 3). The effect of target class was partially mediated by compassion (Studies 2 and 3) and perceived deservingness of the target (Study 3). Implications and limitations are discussed.

How may feelings of love and hate impact people's attention? We used a modified Attentional Blink (AB) task in which 300 participants were asked to categorise a name representing a person towards whom they felt either hate, love, or neutral (first target) plus identify a number word (second target), both embedded in a rapidly presented stream of other words. The lag to the second target was systematically varied. Contrary to our hypothesis, results revealed that both hated and loved names resulted in higher accuracy for the second target than neutral names, which was largely independent of lag. Also, there we observed no sustained transfer effects of love and hate onto neutral name trials. The findings differ from prior research on attentional blink and transient, non-personal, stimulus-driven emotions, suggesting that interpersonal feelings activate different attention-relevant mechanisms. Relevant to future research, we speculate that love and hate are motivators of goal-directed behaviour that facilitate subsequent information processing. [ABSTRACT FROM AUTHOR]

Even before COVID-19, it was well known in psychological science that people's well-being is strongly served by the quality of their close relationships. But is well-being also served by social contact with people who are known less well? In this article, we discuss three propositions that support the conclusion that the benefits of social contact also derive from interactions with acquaintances and even strangers. The propositions state that most interaction situations with strangers are benign (Proposition 1), that most strangers are benign (Proposition 2), and that most interactions with strangers enhance well-being (Proposition 3). These propositions are supported, first, by recent research designed to illuminate the primary features of interaction situations. This research shows that situations with strangers often represent low conflict of interest. Also, in interactions with strangers, most people exhibit high levels of low-cost cooperation (social mindfulness) and, if the need is urgent, high levels of high-cost helping. We close by sharing research examples showing that even very subtle interactions with strangers yield short-term happiness. Broader implications for COVID-19 and urbanization are discussed.

As a complement to high-cost cooperation as assessed in economic games, the concept of social mindfulness focuses on low-cost acts of kindness. While social mindfulness seems quite natural, performed by many most of the time (reaching a level of 60-70 percent), what happens if such acts become more costly, and if costs become more salient? The present research replicates the prevalence of social mindfulness when costs are salient, but low. Yet we show that, with small increments in costs, the vast majority no longer exhibits social mindfulness. This holds even if we keep the outcomes for self high in comparison with the beneficiary. We conclude that the literature on social mindfulness should pay attention to cost. Clearly, if being socially mindful comes with high costs, this is not what most people are prepared to do. In contrast as long as costs are low and not salient, social mindfulness seems natural and normative. [ABSTRACT FROM AUTHOR]

Are there systematic trends around the world in levels of creativity, aggressiveness, life satisfaction, individualism, trust, and suicidality? This article suggests a new field, latitudinal psychology, that delineates differences in such culturally shared features along northern and southern rather than eastern and western locations. In addition to geographical, ecological, and other explanations, we offer three metric foundations of latitudinal variations: replicability (latitudinal gradient repeatability across hemispheres), reversibility (north-south gradient reversal near the equator), and gradient strength (degree of replicability and reversibility). We show that aggressiveness decreases whereas creativity, life satisfaction, and individualism increase as one moves closer to either the North or South Pole. We also discuss the replicability, reversibility, and gradient strength of (a) temperatures and rainfall as remote predictors and (b) pathogen prevalence, national wealth, population density, and income inequality as more proximate predictors of latitudinal gradients in human functioning. Preliminary analyses suggest that cultural and psychological diversity often need to be partially understood in terms of latitudinal variations in integrated exposure to climate-induced demands and wealth-based resources. We conclude with broader implications, emphasizing the importance of north-south replications in samples that are not from Western, educated, industrialized, rich, and democratic (WEIRD) societies.

Acting prosocially can be quite challenging in one of the most salient intergroup contexts in contemporary society: Soccer. When winning is the ultimate goal, balancing self-interest with helping a fellow player in distress can be a tough decision; yet it happens. To date, we know little about what motivates soccer players to offer such help in the heat of the game. We propose that sex and what is at stake will matter in such prosocial dilemma situations. A pilot study (N = 107) indicated that female players may be more likely to help than male players, but this difference was only observed when the players are close to scoring position rather than far away from the goal (midfield). The main study (N = 366) finds that young soccer players show elevated inclinations to help in low-stakes situations, for example when their team is winning or when the outcome of the game seems pretty much decided. Contrariwise, helping intentions decline in high-stakes situations, for example when one’s own team is losing, when one is close to a scoring position in the offense (rather than at the midfield), or when the outcome of the game is still uncertain. Furthermore, female players show somewhat greater inclinations to help than their male counterparts. The current data point at some differences for male and female soccer players, albeit small in effect size. In contrast, we conclude that especially quick cost-benefit judgments regarding the stakes can play a major role in decisions to help or not to help another player on the soccer field.

Can psychological science offer evidence-based solutions to climate change? Using insights and principles derived from the literature on social dilemmas and human cooperation, we discuss evidence in support of three solutions: crossing the borders of thought, time, and space. First, borders of thought could be crossed by using persuasion that is concrete and tailored to local circumstances and by highlighting information about people’s efforts as evidence against the myth of self-interest. Second, borders of time could be crossed by using kinship cues, which can help make the future less distant, and relatively uninvolved advisors, who may help make the future salient. And third, borders of space could be crossed by showing group representatives how they might benefit from a frame of altruistic competition—focusing on the benefits of being seen as moral and global in orientation. Our overall conclusion is that psychological science can offer evidence-based solutions to climate change. [ABSTRACT FROM AUTHOR]

Aggression and violence levels generally increase as one moves closer to the equator, but why? We developed a new theoretical model, CLimate, Aggression, and Self-control in Humans (CLASH; van Lange, Rinderu, & Bushman, 2017b, 2017c), to understand differences within and between countries in aggression and violence in terms of differences in climate. Colder temperatures, and especially larger degrees of seasonal variation in climate, call for individuals and groups to adopt a slower life history strategy, revealed in a greater focus on the future (vs. present) and a stronger focus on self-control—variables that are known to inhibit aggression and violence. Other variables (e.g., wealth, income inequality, parasite stress) are also linked to both climate differences and to aggression and violence differences. When people think of the consequences of climate change, they rarely think of the impact on aggression and violence levels, but they should. CLASH has broad implications for the effects of climate change on intergroup conflict. [ABSTRACT FROM AUTHOR]

The evolution of cooperation is a major question in the biological and behavioral sciences. While most theoretical studies model cooperation in the context of an isolated interaction (e.g., a Prisoner's Dilemma), humans live in heterogeneous social environments, characterized by large variations in fitness interdependence--the extent to which one's fitness is affected by others. Theoretical and experimental work indicates that humans can infer, and respond to, variations in interdependence. In a heterogeneous ancestral environment, these psychological mechanisms to infer fitness interdependence could have provided a selective advantage, allowing individuals to maximize their fitness by deciding when and with whom to cooperate. Yet, to date, the link between cognitive inference, variation in fitness interdependence, and cooperation remains unclear. Here we introduce a theoretical framework to study the evolution of inference and cooperation in heterogeneous social environments, where individuals experience interactions with varying levels of corresponding interests. Using a combination of evolutionary game theory and agent-based modeling, we model the evolution of adaptive agents, who incur a cost to infer interdependence, in populations of fixed-behavior agents who always cooperate or defect. Our results indicate that natural selection could promote the evolution of psychological mechanisms to infer fitness interdependence, provided that there is enough variation in fitness interdependence to offset the cost of inference. Under certain conditions, the fixation of adaptive agents results in higher levels of cooperation. This depends crucially on the type of inference performed and the features of the interdependence landscape. [ABSTRACT FROM AUTHOR]

Research from evolutionary psychology suggests that the mere presence of eye images can promote prosocial behavior. However, the ''eye images effect'' is a source of considerable debate, and findings across studies have yielded somewhat inconsistent support. We suggest that one critical factor may be whether the eyes really need to be watching to effectively enhance prosocial behavior. In three experiments, we investigated the impact of eye images on prosocial behavior, assessed in a laboratory setting. Participants were randomly assigned to view an image of watching eyes (eyes with direct gaze), an image of nonwatching eyes (i.e., eyes closed for Study 1 and averted eyes for Studies 2 and 3), or an image of flowers (control condition). Upon exposure to the stimuli, participants decided whether or not to help another participant by completing a dull cognitive task. Three independent studies produced somewhat mixed results. However, combined analysis of all three studies, with a total of 612 participants, showed that the watching component of the eyes is important for decision-making in this context. Images of watching eyes led to significantly greater inclination to offer help as compared to images of nonwatching eyes (i.e., eyes closed and averted eyes) or images of flowers. These findings suggest that eyes gazing at an individual, rather than any proxy to social presence (e.g., just the eyes), serve as a reminder of reputation. Taken together, we conclude that it is ''eyes that pay attention'' that can lift the veil of anonymity and potentially facilitate prosocial behavior. [ABSTRACT FROM AUTHOR]

Psychology has been "zooming in" on individuals, dyads, and groups with a narrow lens to the exclusion of "zooming out," which involves placing the targeted phenomena within more distal layers of influential context. Here, we plea for a paradigm shift. Specifically, we showcase largely hidden scientific benefits of zooming out by discussing worldwide evidence on inhabitants' habitual adaptations to colder-than-temperate and hotter-than-temperate habitats. These exhibits reveal two different types of theories. Clement-climate perspectives emphasize that generic common properties of stresses from cold and hot temperatures elicit similar effects on personality traits and psychosocial functioning. Cold-versus-heat perspectives emphasize that specific unique properties of stresses from cold and hot habitats elicit different effects on phenomena, such as speech practices and intergroup discrimination. Both zooming-out perspectives are then integrated into a complementary framework that helps identify explanatory mechanisms and demonstrates the broader added value of embedding zooming-in approaches within zooming-out approaches. Indeed, zooming out enriches psychology. [ABSTRACT FROM AUTHOR]

Research has shown that the mere presence of stimuli that resemble eyes is sufficient to attract attention, elicit aesthetic responses, and can even enhance prosocial behavior. However, it is less clear whether eye-like stimuli could also be used as a tool for nature conservation. Several animal species, including butterflies, develop eye-like markings that are known as eyespots. In the present research, we explored whether the mere display of eyespots on butterfly wings can enhance: (a) liking for a butterfly species, and (b) attitudes and behaviors towards conservation of a butterfly species. Four online experimental studies, involving 613 participants, demonstrated that eyespots significantly increased liking for a butterfly species. Furthermore, eyespots significantly increased positive attitudes towards conservation of a butterfly species (Studies , and ), whereas liking mediated the eyespot effect on conservation attitudes (). However, we also found some mixed evidence for an association between eyespots and actual conservation behavior (Studies and ). Overall, these findings suggest that eyespots may increase liking for an animal and sensitize humans to conservation. We discuss possible implications for biodiversity conservation and future research directions. [ABSTRACT FROM AUTHOR]

This article addresses generalized trust, a construct that is examined in various scientific disciplines and assumed to be of central importance to understanding the functioning of individuals, groups, and society at large. We share four basic lessons on trust: (a) Generalized trust is more a matter of culture than genetics; (b) trust is deeply rooted in social interaction experiences (that go beyond childhood), networks, and media; (c) people have too little trust in other people in general; and (d) it is adaptive to regulate a “healthy dose” of generalized trust. Each of these lessons is inspired and illustrated by recent research from different scientific disciplines. [ABSTRACT FROM PUBLISHER]

Nearly 25 years ago, four studies examined the development of social value orientation (SVO) and uncovered that SVO was related to specific and general adult attachment, the number of siblings, and age. However, some of these findings have been challenged by two recent replication studies. The present (pre-registered) research extends these replication studies and the original research by using multiple measurements of both SVO and adult attachment on two large samples that allowed us to detect small effect sizes. With online samples (N = 1446 and 2644) from MTurk and Prolific, we replicated earlier findings that prosociality was associated with a greater level of secure attachment and a lower level of avoidant attachment. Moreover, prosociality was positively related to the number of siblings, especially sisters, as discovered by Study 3 of the original study. However, we failed to replicate the significant relation between SVO and age. Generally, we conclude that prosocial orientation is associated—even if modestly—with secure and avoidant attachment and the number of siblings, but the link with age is a question open to future investigation.

Over the past decades, numerous twin studies have revealed moderate to high heritability estimates for individual differences in a wide range of human traits, including cognitive ability, psychiatric disorders, and personality traits. Even factors that are generally believed to be environmental in nature have been shown to be under genetic control, albeit modest. Is such heritability also present in social traits that are conceptualized as causes and consequences of social interactions or in other ways strongly shaped by behavior of other people? Here we examine a population-based sample of 1,012 twins and relatives. We show that the genetic influence on generalized trust in other people (trust-in-others: h2 = 5%, ns), and beliefs regarding other people’s trust in the self (trust-in-self: h2 = 13%, ns), is virtually absent. As test-retest reliability for both scales were found to be moderate or high (r = .76 and r = .53, respectively) in an independent sample, we conclude that all variance in trust is likely to be accounted for by non-shared environmental influences. We show that, relative to cognitive abilities, psychiatric disorders, and classic personality variables, genetic influences are smaller for trust, and propose that experiences with or observations of the behavior of other people shape trust more strongly than other traits.

Many theories of trust emphasize that trust is most relevant to behavior in situations involving a conflict of interests. However, it is not clear how trust relates to behavior across situations that differ in the degree of conflicting interest: Does trust matter more when the conflict of interest is sma!l or large? According to an interdependence perspective, trust becomes an especially important determinant of behavior in situations involving larger, compared to smaller, degrees of conflicting interests. To examine this perspective, we conducted a meta-analysis involving 212 effect sizes on the relation between trust (both state and dispositional trust in others) and cooperation in social dilemmas--situations that involve varying degrees of conflict between self-interest and collective interest. Results revealed that the positive relation between trust and cooperation is stronger when there is a larger, compared to smaller, degree of conflict. We also examined several other possible moderators of the relation between trust and cooperation. The relation between trust and cooperation was stronger during individual, compared to intergroup, interactions but did not vary as a function of the situation being either a one-shot or repeated interaction. We also find differences across countries in the extent that people condition their own cooperation based on their trust in others. We discuss how the results support an emerging consensus about trust being limited to situations of conflict and address some theoretical and societal implications for our understanding of how and why trust is so important to social interactions and relationships.

Punishment promotes contributions to public goods, but recent evidence suggests that its effectiveness varies across societies. Prior theorizing suggests that cross-societal differences in trust play a key role in determining the effectiveness of punishment, as a form of social norm enforcement, to promote cooperation. One line of reasoning is that punishment promotes cooperation in low-trust societies, primarily because people in such societies expect their fellow members to contribute only if there are strong incentives to do so. Yet another line of reasoning is that high trust makes punishment work, presumably because in high-trust societies people may count on each other to make contributions to public goods and also enforce norm violations by punishing free riders. This poses a puzzle of punishment: Is punishment more effective in promoting cooperation in high- or low-trust societies? In the present article, we examine this puzzle of punishment in a quantitative review of 83 studies involving 7,361 participants across 18 societies that examine the impact of punishment on cooperation in a public goods dilemma. The findings provide a clear answer: Punishment more strongly promotes cooperation in societies with high trust rather than low trust. [ABSTRACT FROM AUTHOR]

The construction and development of theory is one of the central routes to scientific progress. But what exactly constitutes a good theory? What is it that people might expect from an ideal theory? This article advances a new model, which delineates truth, abstraction, progress, and applicability as standards (TAPAS) for a good theory. After providing the rationale for TAPAS, this article evaluates several social-psychological theories in terms of TAPAS, especially classic theories, and illustrates its utility with some more recent theoretical contributions of social psychology. This article concludes by outlining recommendations for effective theory construction and development, such as the utility of meta-analytic approaches for pursuing truth, the utility of theory-oriented courses and journals for pursuing abstraction, and the utility of adversarial collaboration for pursuing progress, and reaching out to major personal or societal issues for pursuing applicability.

Do political preferences reflect individual differences in interpersonal orientations? Are conservatives less other-regarding than liberals? On the basis of past theorising, we hypothesised that, relative to individuals with prosocial orientations, those with individualistic and competitive orientations should be more likely to endorse conservative political preferences and vote for conservative parties. This hypothesis was supported in three independent studies conducted in Italy (Studies 1 and 2) and the Netherlands (Study 3). Consistent with hypotheses, a cross-sectional study revealed that individualists and competitors endorsed stronger conservative political preferences than did prosocials; moreover, this effect was independent of the association between need for structure and conservative political preferences (Study 1). The predicted association of social value orientation and voting was observed in both a four-week (Study 2) and an eight-month (Study 3) longitudinal study. Taken together, the findings provide novel support for the claim that interpersonal orientations, as measured with experimental games rooted in game theory, are important to understanding differences in ideology at the societal level.

Cooperation in social dilemmas is often challenged by negative noise, or unintended errors, such that the actual behavior is less cooperative than intended—for example, arriving later than intended for a meeting due to an unusual traffic jam. The present research was inspired by the notion that doing a little more for one's interaction partner, which may be movitvated by empathetic feelings, can effectively reduce the detrimental effects of “negative noise,” or unintended incidents of noncooperation. Consistent with hypotheses, negative noise exhibited detrimental effects on cooperation, but such effects were absent when empathy-motivated cooperation was present. We conclude that empathy has broad benefits for social interaction, in that it can be an effective tool for coping with misinterpreted behaviors, thereby maintaining or enhancing cooperation.

An obituary for relationship science scholar Caryl Rusbult is presented.

How do we interpret other's behavior when we lack important pieces of information? Do we give the other the benefit of the doubt, believing that the other behaves in a fair manner? Or do we “fill in the blanks” with self-interest? To address these questions, we designed a new method—the dice-rolling paradigm—in which participants observed another person assigning outcomes by rolling two dice and allocating one of them to the participant, who only had information about one of the two dice. Using different baselines, the results revealed that participants underestimated the outcomes the other allocated to the participants, and overestimated the outcomes the other allocated to self, indicating that people assume self-interest from others when information is incomplete.

The authors present an interdependence theoretical framework and advance the argument that generosity serves the important purpose of communicating trust, which is assumed to be of utmost importance to coping with incidents of negative noise (i.e., when the other every now and then behaves less cooperatively than intended). Using a new social dilemma task (the parcel delivery paradigm), it was hypothesized that incidents of negative noise would exert detrimental effects on trust and trust-related judgments and experiences, as well as cooperation, and that relative to tit for tat and self-regarding strategies (stingy or unconditionally cooperative strategies), other-regarding strategies (i.e., unconditional cooperation and generosity) would be more effective at reducing such as detrimental effects. Results from 2 studies provided strong support for these hypotheses, suggesting that the power of generosity is underestimated in the extant literature, especially in its ability to maintain or build trust, which is essential for coping with noise.

Sometimes people may no longer engage in conservational behavior (e.g., to reduce emissions) because their attempts to do so have been thwarted by “negative noise”, or external forces that may cause otherwise cooperative intentions to translate into non-cooperative action (e.g., strikes prevented to commute by public transport rather than by car). The purpose of the present research is to examine whether experiences with negative noise in a commons dilemma may undermine conservational motivation and behavior, even in a subsequent commons dilemma that is free of noise. Participants first interacted in a commons dilemma task—with noise versus without noise—in which the common pool was sustained versus deteriorating. Afterwards, participants were involved in an identical second task in the same pool size condition but noise-free for everybody. Consistent with hypotheses, participants who faced noise and a deteriorating resource in the first task exhibited lower levels of conservation in the second task than did participants who were always acting free of noise. This pattern was mediated by a reduced motivation to preserve the common pool, suggesting that the experience of noise in combination with a decline in collective resources may especially undermine cooperative motivation and behavior.

Despite the pervasive use of promises and threats in social life, very little research has been devoted to examining the effectiveness of these interpersonal tactics in promoting cooperation in social dilemmas. Based on the Goal-Prescribes-Rationality principle, we hypothesized that cooperation should be most strongly enhanced when promises and threats are communicated in combination, rather than in isolation. Also, we hypothesized that the combination of promises and threats should be especially effective among individuals with prosocial rather than proself orientations. Two studies provided good evidence for the latter hypothesis, in that the combination of promises and threats was only effective in people with prosocial orientations, people who are concerned with equality and collective interest.

The current research addresses the psychological benefits of superstitious rituals in top sport, examining the circumstances under which top-class sportspersons are especially committed to enacting rituals prior to a game (ritual commitment). Consistent with the hypotheses, findings revealed that ritual commitment is greater when (a) uncertainty is high rather than low; and (b) importance of the game is high rather than low. Complementary analyses revealed that the state of psychological tension mediated both effect of importance and uncertainty on ritual commitment. Moreover, players with an external locus of control exhibited greater levels of ritual commitment than did players with an internal locus of control. The results are discussed in terms of the tension-regulation function of superstitious rituals in top sport. [ABSTRACT FROM AUTHOR]

Interactions in social life may be seriously affected by negative noise, whereby actual or perceived behavior is less cooperative than was intended (e.g., arriving late due to an unforeseen traffic jam). The present research examines whether negative noise exerts detrimental effects on impressions and cooperation and whether such effects could be reduced by communication. Consistent with hypotheses, Study 1 revealed that negative noise exerts detrimental effects on both impressions of partners' benign intent and cooperation and that these detrimental effects could be effectively reduced by communication about noise. Study 2 replicated both findings but only for individuals with low trust. Mediation analysis revealed that impressions of benign intent and prosocial interaction goals underlie the positive effects of communication on cooperation. [ABSTRACT FROM AUTHOR]

This study examines preference for commuting to work by car or public transportation (PT) within an expanded social dilemma framework (i.e., one that recognizes the importance of both social and temporal concerns). Commuters completed scales assessing commuting preferences, beliefs regarding the environmental impact of cars, social value orientation (SVO), and the consideration of future consequences (CFC). Preference for PT was higher among commuters who believed that commuting by car harms the environment and among those scoring high in CFC. Most important, a significant two-way interaction revealed that preference for commuting by PT was positively related to beliefs regarding the harmful environmental consequences of commuting by car only among those high in CFC. SVO was unrelated to commuting preferences. In sum, a future orientation may be more important than a prosocial orientation in shaping commuting preferences. [ABSTRACT FROM AUTHOR]

The present research addresses the question of when and why forgiving might enhance psychological well-being. The authors predict that forgiving is associated with enhanced well-being but that this association should be more pronounced in relationships of strong rather than weak commitment. This hypothesis received good support in Studies 1-3. Studies 2 and 3 addressed the issue of why forgiving might be associated with psychological well-being, revealing that this association was reduced after controlling for psychological tension (i.e., a psychological state of discomfort due to conflicting cognitions and feelings). Study 4 revealed that in the context of marital relationships, tendencies toward forgiving one's spouse exhibited a more pronounced association with psychological well-being than did tendencies to forgive others in general.

Interdependence theory presents a logical analysis of the structure of interpersonal situations, offering a conceptual framework in which interdependence situations can be analyzed in terms of six dimensions. Specific situations present specific problems and opportunities, logically implying the relevance of specific motives and permitting their expression. Via the concept of transformation, the theory explains how interaction is shaped by broader considerations such as long-term goals and concern for a partner's welfare. The theory illuminates our understanding of social-cognitive processes that are of longstanding interest to psychologists such as cognition and affect, attribution, and self-presentation. The theory also explains adaptation to repeatedly encountered interdependence patterns, as well as the embodiment of such adaptations in interpersonal dispositions, relationship-specific motives, and social norms.

Interpersonal misunderstanding is often rooted in noise, or discrepancies between intended and actual outcomes for an interaction partner due to unintended errors (e.g., not being able to respond to an E-mail because of a local network breakdown). How can one effectively cope with noise in social dilemmas, situations in which self-interest and collective interests are conflicting? Consistent with hypotheses, the present research revealed that incidents of noise exert a detrimental effect on level of cooperation when a partner follows strict reciprocity (i.e., tit for tat) but that this effect can be overcome if a partner behaves somewhat more cooperatively than the actor did in the previous interaction (i.e., tit for tat plus 1). Also, when noise was present, tit for tat plus 1 elicited greater levels of cooperation than did tit for tat, thereby underscoring the benefits of adding generosity to reciprocity in coping with noise in social dilemmas. The Discussion outlines implications of the present work for theories focusing on self-presentation and attribution, communication, and trust and prorelationship behavior. [ABSTRACT FROM AUTHOR]

The present field study examined commuters' (N = 152) willingness to fund improvements in public transit. Consistent with Samuelson's (1993; Samuelson & Messick, 1995) multiattribute evaluation model of structural change in social dilemmas, support for the transit plan was higher when it was perceived to be (a) effective at reducing congestion and pollution, (b) personally beneficial, and (c) fair in terms of taxes and benefits. Also consistent: with predictions, these relationships were moderated by individual differences in social value orientation (McClintock, 1978; Messick & McClintock, 1968) and the consideration of future consequences (CFC; Strathman, Gieicher, Boninger, & Edwards, 1994). Prosocials responded more to the perceived fairness of the plan, while proselfs responded more to the plan's effectiveness in reducing congestion. Low CFCs responded more to the plan's personal benefits and effectiveness in reducing congestion, while high CFCs responded more to the plan's effectiveness in reducing pollution.

Two studies used a thought-listing technique to examine perceived superiority, or the inclination to regard one's own relationship as better than (and not as bad as) others' relationships. Consistent with the claim that this is a motivated phenomenon--and motivated in part by strong commitment--Study 1 revealed that (a) tendencies toward perceived superiority and (b) the commitment-superiority link are both strongest given psychologically threatening instructions and weakest given accuracy instructions (control instructions are intermediate). Consistent with the claim that this phenomenon serves a functional purpose, Study 2 revealed that earlier perceived superiority predicts later relationship status (persisted vs. ended) and increases over time in dyadic adjustment. Also, commitment accounts for unique variance in perceived superiority beyond self-esteem. [ABSTRACT FROM AUTHOR]

Conspiracy theories have been treated mostly as a homogeneous phenomenon in empirical research. However, to fully understand their causes and consequences, a multifaceted approach to conspiracy theories would be useful. Here, we propose an organizational framework with three facets (groups, ideology, and status) to conceptualize conspiracy theories. Based on a review of recent research, the current contribution highlights the psychological differences between (a) perceived conspiracies within or outside of one’s valued community; (b) ideological versus nonideological conspiracy beliefs, based on whether conspiracy beliefs are directly relevant for people’s core values; and (c) upward versus downward conspiracy beliefs, that is, whether the perceived conspiracy involves a relatively high- or low-status group. Finally, we discuss some distinct consequences of these facets in affecting societally consequential behaviors, such as collective action, protest, hostility, or polarization. [ABSTRACT FROM AUTHOR]

This manuscript describes a preliminary study examining judgments of authors and reviewers regarding manuscripts that have been either accepted or rejected for publication. Consistent with hypotheses, results reveal that participants believe that their own manuscripts are superior to others' manuscripts in terms of general, theoretical, and methodological quality. Relevant to the presumed tendency among reviewers to stress limiting aspects of manuscripts (SLAM), reviewers exhibited greater agreement with editorial decisions favoring rejection, relative to those favoring acceptance. These findings suggest that authors' beliefs in reviewers' tendencies to SLAM can be partially understood in terms of authors' unrealistically favorable and optimistic beliefs regarding their manuscripts and in reviewers' actual tendencies to be quite critical--at least more critical than editors.

The authors address locomotion in social dilemmas, examining the influence of social value orientation (prosocial, individualistic, and competitive orientations) and partner's strategy (100% cooperation, tit for tat, and 100% noncooperation) on cooperative behavior and locomotion to enhanced or reduced levels of interdependence (tendencies toward approach vs. avoidance). Extending prior research on behavioral assimilation (e.g., H. H. Kelley & A. J. Stahelski, 1970), results revealed that a noncooperative partner elicited not only relatively low levels of cooperation but also locomotions to low interdependence. Also, relative to prosocials and individualists, competitors exhibited low levels of cooperation and locomotions to low interdependence with a tit-for-tat partner. This underscores the functionality of tit for tat, in that it moves away those who seek relative advantage, thus minimizing the costs following from noncooperative interactions.

The author provides a conceptual framework for understanding differences among prosocial, individualistic, and competitive orientations. Whereas traditional models conceptualize prosocial orientation in terms of enhancing joint outcomes, the author proposes an integrative model of social value orientation in which prosocial orientation is understood in terms of enhancing both joint outcomes and equality in outcomes. Consistent with this integrative model, prosocial orientation (vs. individualistic and competitive orientations) was associated with greater tendencies to enhance both joint outcomes and equality in outcomes; in addition, both goals were positively associated (Study 1). Consistent with interaction-relevant implications of this model, prosocial orientation was strongly related to reciprocity. Relative to individualists and competitors, prosocials were more likely to engage in the same level of cooperation as the interdependent other did (Study 2) and the same level of cooperation as they anticipated from the interdependent other (Study 3).

The present research examines how a single behaviour that is informative of both the morality and intelligence of a person influences impressions, degree of cooperative behaviour expected from that person, and degree of cooperative behaviour displayed toward that person in a mixed-motive interdependence situation (i.e., a social dilemma). Furthermore, it is investigated how individual differences in social value orientation influence these processes. Participants were provided with behavioural information that could be construed in terms of both morality (high/low) and intelligence (high/low). Consistent with the morality-importance hypothesis, participants assigned greater weight to morality than to intelligence aspects of the information. Congruent with the social value orientation hypothesis (i) only proselfs and not prosocials expected more cooperation from unintelligent than from intelligent others, and (ii) prosocials attended more strongly to morality aspects than proselfs in deciding on own cooperation. Finally, consistent with the relative benefit hypothesis, people overall expected more cooperation than they were willing to display, and this tendency was especially pronounced with others described by moral/unintelligent behaviour, and for people with a proself value orientation. The authors discuss a model describing influences of the perceiver and the perceived on cooperative behaviour. Copyright © 1999 John Wiley & Sons, Ltd. [ABSTRACT FROM AUTHOR]

Two studies investigated how behavioral information about the morality or intelligence of another person influences impressions, expectations of cooperative behavior, and own cooperation in a mixed-motive interdependence situation. Consistent with the morality-importance hypothesis results revealed that morality information influenced impressions, expectations of other's cooperative behavior, as well as own cooperation more strongly than intelligence information, and led to greater confidence in expectations and better recall. Consistent with the negativity effect hypothesis negative information about morality and intelligence had more impact on impressions and interaction-relevant measures than positive information. An additional finding was that people overall expected more cooperation from others than they were willing to display themselves, and that this difference was especially pronounced for unintelligent and moral targets. Explanations and implications are discussed from a behavioral-adaptive perspective on impression formation. Copyright © 1999 John Wiley & Sons, Ltd. [ABSTRACT FROM AUTHOR]

This research adopted an interdependence analysis of sacrifice, examining the link between commitment (i.e., the subjective experience of dependence and long-term orientation) and willingness to sacrifice in ongoing close relationships, and determining whether this link is moderated by preexisting individual differences in social value orientation (i.e., prosocial, individualistic, or competitive orientation). Consistent with hypotheses, results of 2 studies revealed both that willingness to sacrifice was associated with greater commitment and that this link was more pronounced among individualists than among prosocials. Results also revealed an association between one's own willingness to sacrifice and beliefs regarding the partner's willingness to sacrifice (this link was somewhat more pronounced among prosocials than among individualists) and one's own willingness to sacrifice and actual partner's willingness to sacrifice.

The authors adopt an interdependence analysis of social value orientation, proposing that prosocial, individualistic, and competitive orientations are (a) partially rooted in different patterns of social interaction as experienced during the periods spanning early childhood to young adulthood and (b) further shaped by different patterns of social interaction as experienced during early adulthood, middle adulthood, and old age. Congruent with this analysis, results revealed that relative to individualists and competitors, prosocial individuals exhibited greater levels of secure attachment (Studies 1 and 2) and reported having more siblings, especially sisters (Study 3). Finally, the prevalence of prosocials increased--and the prevalence of individualists and competitors decreased--from early adulthood to middle adulthood and old age (Study 4).

The authors advance an interdependence analysis of willingness to sacrifice. Support for model predictions was revealed in 6 studies (3 cross-sectional survey studies, 1 simulation experiment, 2 longitudinal studies) that used a novel self-report measure and a behavioral measure of willingness to sacrifice. Willingness to sacrifice was associated with strong commitment, high satisfaction, poor alternatives, and high investments; feelings of commitment largely mediated the associations of these variables with willingness to sacrifice. Moreover, willingness to sacrifice was associated with superior couple functioning, operationalized in terms of level of dyadic adjustment and probability of couple persistence. In predicting adjustment, willingness to sacrifice accounted for significant variance beyond commitment, partially mediating the link between commitment and adjustment; such mediation was not significant for persistence.

The present study examines a two-person give-some dilemma characterized by the conflict between the pursuit of own benefits (not giving) and collective benefits (giving). The major purpose was two-fold: (a) to examine the effects of person perceptions manipulated along the dimensions of morality (goodness) and potency (strength) on co-operation, and (b) to examine whether pre-existing differences between individuals in their preference for specific self-other outcome distributions (social values) would modify the effects of person perception. First, we predicted and found that across social values the degree of co-operative behaviour increased as a linear function of the extent to which the other was seen as moral. Concerning the perceptions in terms of potency, we found a significant quadratic trend; another seen as moderate on potency elicited more co-operative behaviour than another seen as either high or low on potency. These effects of person perception were not moderated by social value. More interesting was the finding that even though persons classified as pro-social (co-operators and altruists) and pro-self (individuals and competitors) held about the same expectation about the magnitude of another's co-operation, pro-socials behaved more co-operatively than pro-self. This suggests that under certain conditions behavioural differences pro-socials and pro-self are not conditional upon expectational differences between those two social values.

In the current field experiment we evaluate a structural solution to a real-life social dilemma by examining the effects of a carpool priority lane on judgments and preferences concerning the decision to commute by carpool (i.e., the presumed cooperative option) or driving alone (i.e., the presumed non-cooperative option). Our general hypothesis was that this intervention would evoke a process of self-justification in solo drivers, arising from feelings of relative deprivation and/or cognitive dissonance. Consistent with predictions, we found that in comparison with judgments made before the implementation of the carpool lane, solo drivers tended to decrease the importance of an attribute inherently linked to carpooling (i.e., low travel costs) and to increase the importance of an attribute inherently linked to driving alone (i.e., flexibility). Moreover, solo drivers exhibited a weaker preference for carpooling after the establishment of the carpool lane. This finding suggests that the negative side effects of this structural measure were more pronounced than the intended carpool-promoting effects. [ABSTRACT FROM AUTHOR]

The present study examines a two-person social dilemma characterised by the conflict between the pursuit of own benefits and collective benefits. The main purpose is twofold: (1) to examine the effect of perceptions of one person's morality (e.g. honesty) on expected cooperation from another and own cooperation, and (2) to examine whether pre-existing differences between individuals in their social value orientation, or preferences for certain patterns of outcomes to self and others (McClintock, 1978), would modify these effects of other's morality. As predicted on the basis of the Might over Morality hypothesis (Liebrand, Jansen et al., 1986), it was found that considerably more cooperation was expected from one perceived as highly moral than from another perceived as low on morality. Contrary to a second Might over Morality prediction, however, this effect was not moderated by individual differences in social value orientation. In addition, it was found that subjects with pro-social value orientations, as well as those with individualistic and competitive orientations cooperated considerably more with a person perceived as highly moral than with another perceived as low on morality. This latter finding extends previous work on social value orientation in that it suggests that individuals who are predisposed to choose noncooperatively in social dilemmas are willing to cooperate if they are quite confident that the other has truly cooperative and good intentions. Finally, the aforementioned findings were observed in two experiments, one conducted in The Netherlands, the other in the United States. This supports the cross-cultural generalisability of the present findings. [ABSTRACT FROM AUTHOR]

The current research examines the role of social value orientation in determining the extent to which individuals are inclined to reciprocate cooperation exhibited by others perceived as either honest, intelligent, or unintelligent. Results revealed that individuals with prosocial orientation reciprocated high levels of cooperation regardless of other's characteristics. Individuals with proself orientation (i.e. individualists and competitors) exhibited some reciprocal cooperation toward others perceived as honest, yet took advantage of others perceived as intelligent or unintelligent. These results suggest that proselfs can be motivated to reciprocate cooperation by others if they have faith in others' benign intentions and trustworthiness. © 1998 John Wiley & Sons, Ltd.

This research provides evidence for the generality of the Muhammad Ali effect (Allison, Messick, & Goethals, 1989), demonstrating that Dutch participants believe that the trait honesty is more descriptive of the self than of others, whereas the trait intelligence is believed to be equally descriptive of the self and others. Congruent with proposed explanations for the Muhammad Ali effect, participants regard honesty as more desirable, more controllable, and less verifiable than intelligence. Mediation analyses indicated that the Muhammad Ali effect is stronger among participants who view honesty as more desirable than intelligence. © 1998 John Wiley & Sons, Ltd. [ABSTRACT FROM AUTHOR]
