Attachment theory provides a useful framework for understanding emotional reactions to separation and loss and the process of adapting to these painful events. In this paper, we review adult attachment studies that have examined emotional reactions and adjustment to separation and loss in romantic and marital relationships. We begin with a brief account of attachment theory. Next, we review studies

Impulsive and risky decision-making peaks in adolescence, and is consistently associated with the neurodevelopmental disorder Attention-Deficit/Hyperactivity Disorder (ADHD), regardless of age. In this brief review, we demonstrate the similarity of theoretical models explaining impulsive and risky decision-making that originate in two relatively distinct literatures (i.e. on adolescence and on ADHD)

Fossil fuel-based development has resulted in climate change and biodiversity loss, threatening the ability of the biosphere to sustain civilization. However, despite the transformative change needed to address climate change, the complexity inherent in dynamic, coupled social-ecological systems can create challenges that stifle mitigation and adaptation efforts. For example, increasing urbanization

Adolescence is a period of rapid change, with cognitive, mental wellbeing, environmental biological factors interacting to shape lifelong outcomes. Large, longitudinal phenotypically rich data sets available for reuse (secondary data) have revolutionized the way we study adolescence, allowing the field to examine these unfolding processes across hundreds or even thousands of individuals. Here, we outline

The meaning of success in conversation depends on people's goals. Often, individuals pursue multiple goals simultaneously, such as establishing shared understanding, making a favorable impression, having fun, or persuading a conversation partner. In this article, we introduce a novel theoretical framework, the Conversational Circumplex, to classify conversational motives along two key dimensions: 1)

Adolescence is a period of dynamic change across multiple systems. Concurrent maturation of neural, biological, and psychosocial functioning renders adolescence a time of heightened sensitivity to both negative and positive experiences. Here, we review recent literature across these domains, discuss risk and opportunity in the context of ongoing neural development, and highlight promising directions

We review the logic of an evolutionary perspective on forgiveness, highlighting how insight into the likely function of forgiveness — solving adaptive problems related to acquiring and maintaining social relationships — has productively guided research and theory. A combination of experimental, longitudinal, cross-sectional, and cross-cultural evidence supports the claim that victims' perceptions of

In this article, we outline the current state of research concerning cooperation in the cross-national context. We present several theoretical approaches and empirical findings regarding national differences in cooperation, as well as how cooperation may depend on the national background of the interaction partner. In addition, we discuss the influence of (national) group norms, cultural similarity

Overall, people want to behave ethically. In some cases, temptation steers them away from ethical behavior. In other cases, purely ethical behavior is not possible, because the same behavior entails both ethical and unethical consequences. For example, collaboration with others may require people to be dishonest. We suggest that to justify their choices in such cases, people engage in a moral calculus

Human brain networks undergo pronounced changes during development. The emergence of highly connected hub regions that can support integrated brain function is central to this maturational process, with these areas undergoing a particularly protracted period of development that extends into adulthood. The location of cortical network hubs emerges early but connections to and from hubs continue to strengthen

Few people are as important for an adolescent's development as their parents. However, most research on parent–adolescent relationships describes long-term population-wide effects. Therefore, little is known about everyday interactions between adolescents and parents in individual families. Ecological momentary assessment (EMA) measures families several times a day as they go through daily life. This

One piece of the puzzle to prosocial behavior is understanding its underlying cognitive and affective processes. We discuss how modeling behavior in social dilemmas can be expanded by integrating cognitive theories and attention-based models of decision processes, and models of affective influences on prosocial decision-making. We review theories speaking to the interconnections of cognition and affect

Adolescence is a dynamic period for the development of emotion regulation. For many individuals, emotion regulation skills improve dramatically during adolescence; however, for some youth, adolescence marks the beginning or worsening of psychopathology characterized by difficulties with emotion regulation. In the present review, I describe evidence that caregiving experiences play an outsized role

In this contribution, we review current research on daily-life experiences of trust in diverse and naturally occurring social interactions ranging from close relationships to complete strangers. Experience-sampling methodology allows the joint examination of situational, relational, dispositional, motivational, and behavioral variables in their relation to trust. Thereby, these recent studies advance

Why do humans develop beliefs in supernatural entities that punish uncooperative behaviors? Leading hypotheses maintain that these beliefs are widespread because they facilitate cooperation, allowing their groups to outcompete others in intergroup competition. Focusing on within-group interactions, we present a model in which people strategically endorse supernatural punishment beliefs as intuitive

The extant literature is mostly dichotomized in examining the effect of either prosocial behavior on well-being or well-being on prosocial behavior. After reviewing the emerging line of research on the positive feedback loop between prosocial behavior and well-being, I integrate all up-to-date empirical findings to present a reciprocal model where prosocial behavior begets well-being and well-being

Prior research has found that people’s choices in economic games are often only modestly related to their prosocial personality traits and to mundane prosocial behaviors. The present article reviews the recent literature showing that the strength of these relationships depends on the level of aggregation. Specifically, we demonstrate an increase in behavioral consistency after horizontal aggregation

Prosociality (measured with economic games) is correlated with individual differences in psychological constructs (measured with self-report scales). We review how methods from natural language processing, a subfield of computer science focused on processing natural text, can be applied to understand the semantic content of scales measuring psychological constructs correlated with prosociality. Methods

Executive functions are core to multiple aspects of daily cognitive, social and affective functioning. An extensive body of work has charted developmental trajectories and neural substrates of executive functions through the lifespan. Robust associations between executive functions early in life, and later, wellbeing and success has led to considerable efforts to improve executive functions through

In this review, we describe the development of prosocial behavior in adolescence as a critical inflection period for social adjustment. Experimental research using prosocial giving tasks demonstrates that adolescents differentiate more between recipients and contexts, suggesting increasing ingroup-outgroup differentiation during adolescence. We also demonstrate that social brain development during

High-cost cooperation directed towards strangers is difficult to explain from an evolutionary perspective. Here, it is argued that by studying the behaviours, motivations, and preferences of real-world high-cost cooperators — blood and organ donors — insights can be uncovered into the mechanisms supporting cooperation. In this respect, this article details two novel mechanisms to enhance cooperation

Personality disorders (PDs) are characterized by interpersonal dysfunction and deficits in prosociality are theorized to contribute to this. We review studies linking categorical PDs to prosocial and antagonistic traits and highlight studies that assessed prosocial behavior in PDs via economic games. We structure our review based on the recently proposed affordance framework of prosocial behavior,

Recently Press and Dyson have dramatically changed our view on the Prisoner's Dilemma by proposing a new class of strategies that enforce a linear relationship between the two players' scores. Players adopting ‘extortion’ respond with cooperation to cooperation in most cases, defect in other rounds, but respond to defection with defection. In this way, extortion enforces full cooperation of the partner

The global climate crisis can be perceived as threat to existential human needs like control, certainty and personal existence. These threat appraisals elicit an affective state of individual anxiety – one of the strongest motivators of individual pro-environmental behavior and collective policies and activism. Direct action against threat is associated with other affective approach-motivated states

Pro-environmental behavior, a form of prosocial behavior that ultimately benefits all humanity, is essential for addressing climate change. This review presents pro-environmental behavior in a social dilemma framework describing how non-aligned interests in nested groups (e.g. smaller groups with interests opposing the interests of a superordinate group entailing the smaller groups) and unequal opportunities

In this review, we examine relationships between empathy, prosocial behavior, and moral judgment. We focus on recent evidence for these relationships, with a focus on motivated empathy regulation as an important process that shapes empathic and moral outcomes. In particular, we highlight tradeoffs in contexts that involve competing victims with different needs, such as in large-scale suffering situations

Moral judgments about interpersonal transgressions are shaped by attributions about the actor's mental state (intent), responsibility, and harmful consequences. Curiously, most research has investigated these judgments from a third-party perspective, often overlooking perceptions of the individuals directly involved in the transgression. We address this by reviewing research on how victims and transgressors

The spatiotemporal group-level patterns of brain macrostructural development are relatively well-documented. Current research emphasizes individual variability in brain development, including its causes and consequences. Although genetic factors and prenatal and perinatal events play critical roles, calls are now made to also study brain development in transactional interplay with the different aspects

Peer influence occurs across a wide variety of behavioral domains, which is an important reason for peer-led interventions: interventions in which peers are involved in the delivery of the program. These programs are promising in combatting undesirable behaviors (e.g. risk behavior) and promoting desirable behavior (e.g. healthy lifestyle), but it was shown recently that the effectiveness of these

Mindfulness is a hot topic in psychological research and the popular media. One central claim in the literature is that enhanced mindfulness fosters prosocial behavior. This article recapitulates what is currently known about this widespread claim. We first review theoretical perspectives on why enhanced mindfulness should foster prosocial behavior and discuss relevant empirical evidence. Two meta-analyses

Antibiotic prescribing can be conceptualised as a social dilemma in which the overuse of antibiotics, to minimise immediate risks to individual patients, results in a sub-optimal outcome for society (antimicrobial resistance) and increased risks to all patients in the long run. Doctors face the challenge of balancing the interests of individual patients against the collective good when prescribing

Prosociality is an important part of the work context. Employees, leaders, and organizations show various forms of prosocial behavior such as supporting colleagues suffering from heavy workload, voluntarily organizing social events fostering a good organizational climate, or providing goods and services that benefit society at large. From the plethora of constructs related to prosociality at work,

Moral courage, that is, defending moral beliefs despite personal risks, is often seen as a hallmark of prosocial behavior. We argue that prosociality in moral courage is, however, complex. While its prosociality is often evident at a higher societal level, it can be contested in some aspects of morally courageous acts. We review the literature on two such aspects and highlight that differences and

The field of prosociality is flourishing, yet researchers disagree about how to define prosocial behavior and often neglect defining it altogether. In this review, we provide an overview about the breadth of definitions of prosocial behavior and the related concept of altruism. Common to almost all definitions is an emphasis on the promotion of welfare in agents other than the actor. However, definitions

People usually engage in (or at least profess to engage in) altruistic acts to benefit others. Yet, they routinely fail to maximize how much good is achieved with their donated money and time. An accumulating body of research has uncovered various psychological factors that can explain why people's altruism tends to be ineffective. These prior studies have mostly focused on proximate explanations (e

Much of human learning comes from learning from others. In this article, I review empirical work on the extent to which prosocial behavior is inspired by exposure to prosocial models. In fact, witnessing a prosocial model in person leads to an increase in the future prosocial behavior of the observer. Other research has shown that exposure to media (TV, music, video games) with depictions of prosocial

Reward and punishment change the payoff structures of social interactions and therefore can potentially play a role in promoting prosocial behavior. Yet, there are boundary conditions for them to be effective. We review recent work that addresses the conditions under which rewards and punishment can enhance prosocial behavior, the proximate and ultimate mechanisms for individuals’ rewarding and punishing

We review psychological approaches of helping behavior in the context of refugee immigration. Refugee migration, compared with nonrefugee migration, is characterized by greater forcedness and related perils. Taking into account perceptions of forcedness and perils, we examine potential helpers' responses at each of four successive stages toward helping people in perilous, distressing, or emergency

Intergroup conflict can be modeled as a two-level game of strategy in which prosociality can take the form of trust and cooperation within groups or between groups. We review recent work, from our own laboratory and that of others, that shows how biological and sociocultural mechanisms that promote prosocial preferences and beliefs create in-group bounded, parochial cooperation, and, sometimes, parochial

The sharing economy is fueled by trust, which allows strangers to cooperate. To share responsibly, one needs to be aware of the various consequences sharing has on interacting and third parties. When transparency about such consequences is lacking, mutual trust among interacting parties may encourage people to cooperate and share, in turn, creating unintended negative impacts. Psychologists have long

People who are socially isolated or lonely report having lower levels of social support. Supportive social networks help buffer individuals against the deleterious effects of negative events and stressors. Supportive social networks also help individuals maximize the benefits of positive events and accomplishments. In short, those who are socially isolated suffer more when bad things happen and gain

The path from perspective-taking to prosocial behavior is not as straightforward or robust as it is often assumed to be. In some contexts, imagining the viewpoint of other person leads the perspective taker to thoughts about how that person might have negative thoughts or intentions toward them. It can also prompt other kinds of counter-productive egocentric projection. In this review, we consider

The functioning of social collectives hinges on the willingness of their members to cooperate with one another and to help those who are in need. Here, we consider how such prosocial behavior is shaped by emotions. We offer an integrative review of theoretical arguments and empirical findings concerning how the experience of emotions influences people's own prosocial behavior (intrapersonal effects)

Literature reviews on how social media use affects adolescent mental health have accumulated at an unprecedented rate of late. Yet, a higher-level integration of the evidence is still lacking. We fill this gap with an up-to-date umbrella review, a review of reviews published between 2019 and mid-2021. Our search yielded 25 reviews: seven meta-analyses, nine systematic, and nine narrative reviews. Results

More than 420 million children live amid political conflict. In such settings, understanding the development of prosocial behaviours, specifically directed at outgroups, can provide opportunities for peacebuilding. Informed by research on intergroup competition and structural inequality, we focus on outgroup prosocial behaviour targeting conflict rivals. Already from a young age, children are politically

Although previous research has found that prosocial behavior increases personal and relationship well-being, a particularly costly type of prosocial behavior — sacrifice — can sometimes have aversive effects and is the focus of the current review. We consider effects for both the individual who enacts the sacrifice and the recipient. Sacrifice, can take a toll on the giver's well-being, is a mixed

For most of our species’ history, humans have lived in relatively small subsistence communities, often called small-scale societies. While these groups lack centralized institutions, they can and often do maintain large-scale cooperation. Here, we explore several mechanisms promoting cooperation in small-scale societies, including (a) the development of social norms that encourage prosocial behavior

Humans are regularly in suboptimal psychophysiological states like stressed or hungry. Previous research has made both claims that such impairments should decrease and that they should increase prosocial behaviour. We describe the overarching theoretical reasoning underlying these opposing predictions. Then we discuss empirical research on the two impairments most frequently studied, acute stress and

Prosociality is a core feature of human functioning and has been a topic of interest across disciplinary boundaries for decades. In this review, we highlight different neuroscientific approaches that have enriched traditional psychological methods for studying prosocial behavior among individuals and groups. First, we outline findings from task-based neuroimaging studies that provide correlational

Impression management is a fundamental aspect of social life. From self-promotion to feedback giving, from advice seeking to networking, people frequently find themselves in situations where they need to make a positive impression on others. Despite the long-term benefits of making a favorable impression, impression management attempts can backfire in unintended ways. In this article, I review recent

The network theory of prolonged grief posits that causal interactions among symptoms of prolonged grief play a significant role in their coherence and persistence as a syndrome. Drawing on recent developments in the broader network approach to psychopathology, we argue that advancing our understanding of the causal system that gives rise to prolonged grief will require that we (a) strengthen our assessment

In this article, we examine the empirical and theoretical support for the idea that experiences of isolation can intensify substance use, even among those in committed close relationships, and can increase the likelihood of negative conflict behaviors, including intimate partner violence (IPV). Cross-sectional, longitudinal, and laboratory-based research suggest that individuals and couples who report

Following interpersonal transgressions, both victims and offenders can experience psychological loss owing to threatened needs for agency and moral-social identity. Moral repair is the process by which these losses are restored. Rather than involving only intraindividual static processes, research is starting to recognize that moral repair is dyadic, reciprocal, and interactionist. It involves the

How do people evaluate how much social progress has been achieved, and how do these perceptions influence intergroup attitudes? We present a model summarizing the signals and sense-making that arise when people think about progress. We review the signals that shape progress perceptions when people observe individual exemplars of success from, or substantive advances for, negatively stereotyped groups

Norms prescribe how to make decisions in social situations and play a crucial role in sustaining cooperative relationships and coordinating collective action. However, following norms often requires restricting behavior, demanding to curtail selfishness, or suppressing personal goals. This raises the question why people adhere to norms. We review recent theories and empirical findings that aim at explaining

The onset of parenthood irrevocably changes the landscape of adults' functioning, amplifying the potential for parents' experiences of both developmental losses and gains/growth, in context of increased responsibilities and more limited access to environmental resources/supports. In this article, we draw on dual theoretical lenses to integrate the frameworks of Baltes' lifespan development theory of

In Western dual-educated, male-female marriages, women who divorce face greater burdens because of decreased income and primary or sole responsibility for caring for children than men who divorce. Why, then, do these women initiate divorce more and fare better psychologically after a divorce than men? Here, we articulate an evolutionary mismatch perspective, informed by key findings in relationship

Science is unthinkable without collaboration between scientists. Yet, science is also unthinkable without competition (i.e., competing for the best and most solid arguments and limited, precious resources). In this review, we argue that scientific work routines represent social dilemmas and that two facets of prosociality help researchers solve these dilemmas: (i) sacrificing personal profit for the
