Oxytocin and the emergence of individual differences in the social regulation of stress

The ability to use social support to regulate stress is critical to mental and physical health. Here, we posit that the oxytocin system contributes to the variability in individual responses to social support. We first review the evidence that oxytocin is related to both social functioning and stress regulation. We focus on results from molecular genetics suggesting that individual variations in both of these functions are associated with natural variations in the oxytocin receptor gene (OXTR). We then describe research that exploits this natural variation to directly and experimentally test relationships between the oxytocin system, social support, and stress regulation in both infants and adults. On the basis of our findings, we propose a novel theoretical model of how biological processes might interact with psychological beliefs about relationships—even in infants—to affect long‐term patterns of social regulation of stress.     

The harms of ignoring the social nature of science

In this paper I argue that philosophers of science have an obligation to recognize and engage with the social nature of the sciences they assess if those sciences are morally relevant. Morally-relevant science is science that has the potential to risk harm to humans, non-humans, or the environment. My argument and the approach I develop are informed by an analysis of the philosophy of biology literature on the criticism of evolutionary psychology (EP), the study of the evolution of human psychology and behaviour. From this literature, I tease out two different methods of scientific critique. The first I call the “truth-detectional” approach. Those who take this approach are first and foremost concerned about the truth of EP claims as that truth can be determined by evidence. The second I call the “social-dimensional” approach. Those who take this approach talk about the production and truth of EP claims but within a social framework. On this account, the legitimacy and perceived legitimacy of EP claims are not separate from the institutional and social processes and values that lend to their production. I show that the truth-detectional approach risks harms to society and to the philosophy of science, but that the social-dimensional approach avoids these harms. Philosophers of science, therefore, should take a social-dimensional approach to the assessment of morally-relevant science.

     

Toleration and prejudice-reduction: Two ways of improving intergroup relations

While a large body of social psychological research has shed light on the nature of prejudice and how to reduce it, we argue that such work does not address situations of cultural or religious outgroup beliefs and practices that are considered incompatible with one's own. The present theoretical article contrasts a prejudice-reduction approach with a toleration-based approach to consider the differences each have with regard to the attitude object they focus upon, the perceived reasonableness of the attitude, and the behavioral consequences each may lead to. In doing so, we consider the psychological processes involved in whether the negative attitude leads to negative actions. We conclude by arguing that a toleration-based approach forms an important addition to the psychological thinking about cultural diversity and intergroup relations. Collectively, the present work makes a novel contribution to the social psychological literature by stimulating theory development and raising novel questions for empirical research.     

Conceptual constraints and mechanisms in children's selective learning

Although we can support Heyes’ call for more research on mechanisms, we disagree that the problem has been ignored as Heyes suggests. We also doubt that basic learning mechanisms are alone sufficient to account for the broad range of findings in the selective social learning literature. Although phylogenetically shared learning mechanisms must support selective social learning, we believe that they must also be guided by top‐down conceptual considerations that may be special to humans. Research to date has been focused on establishing the boundary conditions on selective social learning, with the goal of making generalizations that will constrain theorizing about the character of that special knowledge. This is critical to our understanding of both why and how selective social learning manifests in children.     

“Danger,Will Robinson!” The challenges of social robots for intergroup relations

Society's increasing reliance on robots in everyday life provides exciting opportunities for social psychologists to work with engineers in the nascent field of social robotics. In contrast to industrial robots that, for example, may be used on an assembly line, social robots are designed specifically to interact with humans and/or other robots. People tend to perceive social robots as autonomous and capable of having a mind. As such, they are also more likely to be subject to social categorization by humans. As social robots become more human like, people may also feel greater empathy for them and treat robots more like (human) ingroup members. On the other hand, as they become more human like, robots also challenge our human distinctiveness, threaten our identity, and elicit suspicion about their ability to deceive us with their human‐like qualities. We review relevant research to explore this apparent paradox, particularly from an intergroup relations perspective. We discuss these findings and propose three research questions that we believe social psychologists are ideally suited to address.     

Beyond Discrete Categories: Studying Multiracial,Intersex, and Transgender Children Will Strengthen Basic Developmental Science

Developmental research on social categorization has overwhelmingly focused on perceptions about and experiences of individuals who are clear or prototypical members of discrete and usually dichotomous social categories. For example, studies of social categorization, stereotyping, prejudice, and social identity have generally explored how children reason about others who are gender-typical boys or girls or monoracial White or Black children. Similarly, research participants have generally been gender-typical and monoracial. However, our efforts to build theories that account for the true range of variation require acknowledging the increasing visibility of children who do not fit into these discrete categories and raise the question of whether existing theories can capture the dynamics that arise for them. Focusing on race and gender/sex, the social categories that have received the most attention in the developmental literature, we review research that has gone beyond simple dichotomies by including multiracial, gender-nonconforming, or intersex children, either as the targets of social perception or as participants themselves. We argue that this emerging work reveals problematic assumptions built into our theories and methods and highlights the value of building a more inclusive science.     

Social constructionism in the study of career: Accessing the parts that other approaches cannot reach

In this article we consider the contribution of a social constructionist perspective to our understandings of career. We examine this approach in relation to two studies: a study of women's career transition from organizational employment to portfolio work, and a study of the careers of research scientists. Within the career literature a dichotomy has emerged between what are seen as “traditional” and “new” careers. On the face of it these studies seem to neatly illustrate this dichotomy. However, when examined from a social constructionist perspective, questions are raised about the viability of this binarism. In this article we argue this approach enables us to transcend dualisms which have prevailed in career theory, facilitates analyses of the relationship between careers and the social contexts in which they are embedded, and illuminates issues of power and ideology which are often eclipsed by more positivistic research approaches.     

催产素对情绪识别的影响及其机制

催产素(oxytocin)被称为“社会键(social bonds)荷尔蒙”, 时刻影响着社会行为和认知, 其中包括情绪识别。目前, 关于催产素对情绪识别的影响主要有3种观点：(1)催产素选择性地促进个体对积极情绪的识别、减慢对消极情绪的识别; (2)催产素选择性地增强对消极情绪的识别; (3)催产素提高对所有情绪的识别, 与情绪效价无关。催产素影响情绪识别神经机制的研究主要集中在3个方面：情绪效价、性别差异和精神疾病。此外, 还运用社会显著假说解释催产素对情绪识别的作用。催产素可能对情绪识别障碍类精神疾病有潜在的治疗效果, 未来的研究应深入探究催产素与情绪效价的关系, 考虑性别等个体因素的影响, 进一步探讨催产素的临床应用并拓展研究范围。     

Marmosets as a next-generation model of comparative cognition

Common marmosets have traditionally been used in fields such as comparative psychology, cognitive neuroscience, and ethology, and as animal models of human disease research because of their relatively small body size, high reproductive rate, similar breeding system characteristics to those of humans, high dependency on vocal communication, and behavioral effects from drug administration that resemble those of humans. Although the animal has proved to be quite advantageous in animal model research in comparison to rodents, and has specific ecological and evolutionary characteristics that are worthy of exploration, few attempts have been made until recently to combine both types of approach. Thus, supported by neuroscientific methodologies that have recently been developed using this species, the authors suggest that the evolutionary origins of cognitive and social functions common to or differentiated in primates, could be uncovered through research that explores the behavioral and neural bases of cognition in the marmosets.     

催产素对社会善念的提升作用

两个实验考察催产素对社会善念的作用以及面孔吸引力对二者关系的影响。实验1采用双盲实验，使用安慰剂作对照，发现催产素可以促进社会善念，不受面孔性别的影响。实验2依然采用双盲实验，进一步考察面孔吸引力与面孔性别对催产素与社会善念关系的作用，发现催产素对社会善念的作用不受面孔吸引力的影响；女性面孔（与男性面孔相比）吸引力对男性的社会善念影响更大。研究表明，催产素可以稳定地提高社会善念水平。     

Tend and Befriend: Biobehavioral Bases of Affiliation Under Stress

ABSTRACT— In addition to fight-or-flight, humans demonstrate tending and befriending responses to stress—responses underpinned by the hormone oxytocin, by opioids, and by dopaminergic pathways. A working model of affiliation under stress suggests that oxytocin may be a biomarker of social distress that accompanies gaps or problems with social relationships and that may provide an impetus for affiliation. Oxytocin is implicated in the seeking of affiliative contact in response to stress, and, in conjunction with opioids, it also modulates stress responses. Specifically, in conjunction with positive affiliative contacts, oxytocin attenuates psychological and biological stress responses, but in conjunction with hostile and unsupportive contacts, oxytocin may exacerbate psychological and biological stress responses. Although significant paradoxes remain to be resolved, a mechanism that may underlie oxytocin's relation to the health benefits of social support may be in view.     

Ways to independence

Much research attests to the beneficial effects of equine interventions on physical development and ability. However, less is known about the possible psychological benefits of horse activities, such as therapeutic riding or interactions with horses. Although there is public consensus that horses can have psychological benefits, it is an under-researched area and conclusions are largely based on anecdotal data. The little empirical evidence that is available about the efficacy of equine-assisted interventions on psychological outcomes tends to be mixed and is often difficult to interpret due to the lack of rigorous research designs. The purpose of this review was to examine the current state of the literature regarding the psychological effects of equine-assisted interventions, and to make recommendations for future research. Findings from this review suggest that equine-assisted interventions hold much promise, particularly in terms of child/adolescent social and behavioural issues, and perhaps adult affective disorders. However, the current state of the literature does not allow us to definitively conclude that equine-assisted interventions are efficacious. Well-designed randomised controlled trials are greatly needed in this area, as it is an appreciation of the need to standardise and document equine-assisted interventions and outcomes in future research.     

The ‘Fractionable Autism Triad’: A Review of Evidence from Behavioural,Genetic, Cognitive and Neural Research

Autism is diagnosed on the basis of a triad of impairments in social interaction, communication, and flexible imaginative functions (with restricted and repetitive behaviors and interests; RRBIs). There has been a strong presumption that these different features of the syndrome are strongly intertwined and proceed from a common cause at the genetic, cognitive and neural levels. In this review we examine evidence for an alternative approach, considering the triad as largely ‘fractionable’. We present evidence from our own twin studies, and review relevant literature on autism and autistic-like traits in other groups. We suggest that largely independent genes may operate on social skills/impairments, communication abilities, and RRBIs, requiring a change in molecular-genetic research approaches. At the cognitive level, we suggest that satisfactory accounts exist for each of the triad domains, but no single unitary account can explain both social and nonsocial features of autism. We discuss the implications of the fractionable-triad approach for both diagnosis and future research directions.     

Consumer intention to purchase and corporate social responsibility: Evidence from an experiment in an entrepreneurial context

Previous research has addressed the effects of corporate social responsibility (CSR) initiatives on consumer purchase intention (CPI). However, most of the empirical evidence is based on the analysis of mature large-scale firms; much less examines the effects of CSR initiatives on CPI in entrepreneurial contexts. In this study, we address this gap by investigating whether entrepreneurial start-ups' declaration of CSR engagement affects consumers' purchasing intent. We assert that consumers may consider firms' CSR engagement as a signal for unobserved product quality. We exploit a vignette experimental approach to test our theoretical predictions. In our experiment, participants received online invitations to subscribe to an electronic catalog that advertised various products supplied by entrepreneurial start-ups. The invitations are of five types, some of which presenting different CSR-related information on the suppliers to the participants. Overall, we find that the displayed information on CSR engagement promotes participants' willingness to subscribe to the electronic catalog, indicating that consumers will increase their purchase intentions for ethically oriented suppliers. Moreover, we find that among all the initiatives, external CSR initiatives (social contribution and environmental responsibility) promote consumers' intentions to purchase most effectively. To the best of our knowledge, our study is the first to explore the effects of different CSR initiatives on entrepreneurial start-ups in entrepreneurship literature. We highlight the heterogeneous effects of CSR initiatives on CPI, contributing new insights to research on CSR and consumer behavior.     

Collective intentionality and socially extended minds

There are many ways to advance our understanding of the human mind by studying different kinds of sociality. Our aim in this introduction is to situate claims about extended cognition within a broader framework of research on human sociality. We briefly discuss the existing landscape, focusing on ways of defending socially extended cognition. We then draw on resources from the recent literature on the socially extended mind, as well as the literature on collective intentionality, to provide a framework for thinking about the social dimension of individual minds. We then turn to a brief overview of the individualistic approaches advanced by Ludwig and Spaulding in this volume. And we close with a discussion of the transformative role of the social mind in individual life presented by Kern and Moll, as well as the distributed approach to interacting systems defended by Goldstone and Theiner.     

Social identity and psychosis: Explaining elevated rates of psychosis in migrant populations

A substantial body of literature suggests that migrants are at greater risk of developing psychotic symptoms, such as paranoia, compared to non‐migrants. To date, researchers have been unable to identify the primary cause of this effect, finding scarce support for biological, diagnostic, and economic explanations. Social determinants have received little empirical attention in this domain, which we assert is a critical gap in the literature. Here, we propose that the social identity approach offers a framework to help explain the elevated rates of psychosis among migrants, and in turn inform policies and interventions to address this important mental health issue. We propose that cultural identities play a central role in mitigating the psychological precursors of psychosis and that disidentification and social disconnection subsequent to migration could initiate or exacerbate psychosis for multiple generations. We draw together research from social and clinical psychology to detail a social identity approach to psychosis in migrant populations, and make recommendations for future research.     

Asymmetric frontal brain activity and parental rejection predict altruistic behavior: Moderation of oxytocin effects

Asymmetric frontal brain activity has been widely implicated in reactions to emotional stimuli and is thought to reflect individual differences in approach–withdrawal motivation. Here, we investigate whether asymmetric frontal activity, as a measure of approach–withdrawal motivation, also predicts charitable donations after a charity’s (emotion-eliciting) promotional video showing a child in need is viewed, in a sample of 47 young adult women. In addition, we explore possibilities for mediation and moderation, by asymmetric frontal activity, of the effects of intranasally administered oxytocin and parental love withdrawal on charitable donations. Greater relative left frontal activity was related to larger donations. In addition, we found evidence of moderation: Low levels of parental love withdrawal predicted larger donations in the oxytocin condition for participants showing greater relative right frontal activity. We suggest that when approach motivation is high (reflected in greater relative left frontal activity), individuals are generally inclined to take action upon seeing someone in need and, thus, to donate money to actively help out. Only when approach motivation is low (reflected in less relative left/greater relative right activity) do empathic concerns affected by oxytocin and experiences of love withdrawal play an important part in deciding about donations.     

Dominance or prestige: A review of the effects of power poses and other body postures

Research on the effects of body positions has attracted enormous attention in recent years but has been plagued by failed replication attempts. Today, there is some confusion about which effects can be considered reliable. One problem that may have contributed to this confusion is the fact that most previous studies have not clearly distinguished between different types of body positions. We apply the dominance‐prestige framework to distinguish between two types of body positions. On the basis of this reasoning, we argue that research on so‐called power poses in fact has analyzed expansiveness as an indicator of dominance, whereas research on postures has focused on the straightness of the spine, which may be seen as a display of prestige. We review the literature and conclude that there is no clear evidence that short‐term interventions involving body positions affect physiology or behavior. Still, there are effects on actors' self‐perceptions. Repeatedly, studies on power poses have found effects on feelings of power and self‐evaluations, and studies on postures have found effects on emotional experience. However, there is hardly any research that has directly compared the two types of interventions.     

The dot-probe task to measure emotional attention: A suitable measure in comparative studies?

For social animals, attending to and recognizing the emotional expressions of other individuals is of crucial importance for their survival and likely has a deep evolutionary origin. Gaining insight into how emotional expressions evolved as adaptations over the course of evolution can be achieved by making direct cross-species comparisons. To that extent, experimental paradigms that are suitable for investigating emotional processing across species need to be developed and evaluated. The emotional dot-probe task, which measures attention allocation toward emotional stimuli, has this potential. The task is implicit, and subjects need minimal training to perform the task successfully. Findings in nonhuman primates, although scarce, show that they, like humans, have an attentional bias toward emotional stimuli. However, the wide literature on human studies has shown that different factors can have important moderating effects on the results. Due to the large heterogeneity of this literature, these moderating effects often remain unnoticed. We here review this literature and show that subject characteristics and differences in experimental designs affect the results of the dot-probe task. We conclude with specific recommendations regarding these issues that are particularly relevant to take into consideration when applying this paradigm to study animals.
