This paper makes two contributions to the research on cooperation in experimental social dilemmas. First, we demonstrate an interaction between group size and communication in which the effectiveness of communication in promoting cooperation declines as group size increases. Second, we corroborate some previous research showing the positive effect of communication is due to sincere signaling of cooperative intentions. The experimental data comes from 289 undergraduate student subjects playing public goods games over a computer network. These (...) findings suggest that large group size opens up a niche for the evolution of institutions for collective action. (shrink)

The ArgumentThe notion that experimentation provides an appropriate means for acquiring valid knowledge about some aspects of social reality has always depended on certain presuppositions about the nature of social reality and about the role of expenment in knowledge acquisition. In this paper I examine historical changes in these presuppositions from the beginnings of social psychological experimentation to the period after World War II.It was late nineteenth-century crowd psychology that provided the theoretical inspiration fo the first systematic (...) steps in the application of expermental methods to the investigation of social psychological problems. The basic question addressed by these early experiments was derived from the individualistic social ontology of crowd psychology. It was this ontology that made the microcosm of the experimental situation appear relevant to social reality outside this situation.In the 1940s experimental social psychology was briefly influenced by a nonindividualistic social ontology for which group phenomena were real. In the work of Kurt Lewin this was linked to an anti-inductivist conception of experimentation derived from Gestalt psychology and the philosophy of Ernst Cassirer. However, this model proved to be utterly unassimilable by American social psychology which was dominated by an individualistic social ontology and an inductivist philosophy of experimentation that mutually supported each other.

This article is an account of the dynamics of interaction across the social sciences and neurosciences. Against an arid rhetoric of ‘interdisciplinarity’, it calls for a more expansive imaginary of what experiment – as practice and ethos – might offer in this space. Arguing that opportunities for collaboration between social scientists and neuroscientists need to be taken seriously, the article situates itself against existing conceptualizations of these dynamics, grouping them under three rubrics: ‘critique’, ‘ebullience’ and ‘interaction’. Despite their (...) differences, each insists on a distinction between sociocultural and neurobiological knowledge, or does not show how a more entangled field might be realized. The article links this absence to the ‘regime of the inter-’, an ethic of interdisciplinarity that guides interaction between disciplines on the understanding of their pre-existing separateness. The argument of the paper is thus twofold: (1) that, contra the ‘regime of the inter-’, it is no longer practicable to maintain a hygienic separation between sociocultural webs and neurobiological architecture; (2) that the cognitive neuroscientific experiment, as a space of epistemological and ontological excess, offers an opportunity to researchers, from all disciplines, to explore and register this realization.

Are the landscapes of real-world decisions adequately represented in our laboratory tasks? Are the goals and expertise of experimental participants the same as real-world decision-makers? Are we neglecting crucial forces that lead to group outcomes? Are the contingencies necessary for producing experimental demonstrations of bias present in the real world? In the target article, I argued that the answers to these questions are needed to understand whether and how laboratory research can inform real-world group disparities. Most (...) of the commentaries defending experimental social psychology neglected to directly address these main arguments. The commentaries defending implicit bias only revealed the inadequacy of this concept for explaining group disparities. The major conclusions from the target article remain intact, suggesting that experimental social psychology must undergo major changes to contribute to our understanding of group disparities.

A correlational pilot study (N = 143) and an integrative data analysis of two experiments (total N = 377) provide evidence linking anger to the psychology of social hierarchy. The experiments demonstrate that the experience of anger increases the psychological accessibility of implicit cognitions related to social hierarchy: compared to participants in a control condition, participants in an anger-priming condition completed word stems with significantly more hierarchy-related words. We found little support for sex differences in the effect of (...) anger on implicit hierarchy-related cognition; effects were equivalent across male and female participants. Findings fit with functionalist evolutionary views of anger suggesting that anger may motivate the use of dominance to strive for high social rank in group hierarchies. Implications for downstream behaviour, including aggression and negotiation, are discussed. (shrink)

Social media chat groups, such as WeChat and WhatsApp groups, are widely applied in online communication. This research has conducted two studies to examine the individual level and collective level’s opinion dynamics in those groups. The opinion dynamic is driven by two variables, people’s perceived peer support and willingness of opinion expression. The perceived peer support influences the willingness of opinion expression, and the willingness influences the dynamics of real opinion-expression. First, the quasi-experimental study recruited twenty-five participants as (...) the observation group and found that decreasing perceived peer support would significantly increase individuals’ expression willingness to protect his/her opinion. To generalize the individual level findings to a collective level, the second study treated the social media chat groups as an undirected fully-connected social network and simulated people’s opinion expression dynamics with an agent-based model. The simulation indicated that with the help of increased willingness of opinion expression, the minority opinion supporters as a collective did not fall silent but continue to express themselves and increasing willingness of opinion expression would maintain the existence of minority opinion but could not help the minority reverse to the majority.

Psychological essentialism has played an important role in social psychology, informing influential theories of stereotyping and prejudice as well as questions about wrongdoers’ accountability and their ability to change. In the existing literature, essentialism is often tied to beliefs in shared biology—i.e., the extent to which members of a social group are seen as having the same underlying biological features. Here we investigate the possibility of “value-based essentialism” in which people think of certain social groups in (...) terms of an underlying essence, but that essence is understood as a value. Study 1 explored beliefs about a wide range of social groups and found that both groups with shared biology (e.g., women) and shared values (e.g., hippies) elicited similar general essentialist beliefs relative to more incidental social categories (e.g., English-speakers). In Studies 2-4, participants who read about a group either as being based in biology or in values reported higher general essentialist beliefs compared to a control condition. Because biological essences about social groups have been connected to a number of downstream consequences, we also investigated two test cases concerning value-based essentialism. In Study 3, beliefs about both shared biology and shared values increased inductive generalizations about the social group relative to control, but in Study 4, only the shared biology condition reduced blame for wrongdoing. Together these findings join with recent work to support a broader theoretical framework of essentialism about social groups that can be arrived at through multiple pathways, including, in the present case, shared values.

In this paper it is argued that a) altruism is an inadequate label for human cooperative behavior, and b) an adequate account of cooperation has to depart from the standard economic model of human behavior by taking note of the agents' capacity to see themselves and act as team-members. Contrary to what Fehr et al. seem to think, the main problem of the conceptual limitations of the standard model is not so much the assumption of sel shness but rather the (...) atomistic conception of the individual. A much-neglected question of the theory of cooperation is how the agent's social identity is determined, i.e. how individuals come to think of themselves and act as members of a group. Considering as an example one of Fehr et al.'s third party punishment experiments, I shall argue that the agents' identities are strongly in uenced by the way the experiment is presented to the participants, especially by the collectivity-related vocabulary used in the instructions.

This article questions the widespread use of experimental social psychology to understand real-world group disparities. Standard experimental practice is to design studies in which participants make judgments of targets who vary only on the social categories to which they belong. This is typically done under simplified decision landscapes and with untrained decision-makers. For example, to understand racial disparities in police shootings, researchers show pictures of armed and unarmed Black and White men to undergraduates and have (...) them press “shoot” and “don't shoot” buttons. Having demonstrated categorical bias under these conditions, researchers then use such findings to claim that real-world disparities are also due to decision-maker bias. I describe three flaws inherent in this approach, flaws which undermine any direct contribution of experimental studies to explaining group disparities. First, the decision landscapes used in experimental studies lack crucial components present in actual decisions. Second, categorical effects in experimental studies are not interpreted in light of other effects on outcomes, including behavioral differences across groups. Third, there is no systematic testing of whether the contingencies required to produce experimental effects are present in real-world decisions. I apply this analysis to three research topics to illustrate the scope of the problem. I discuss how this research tradition has skewed our understanding of the human mind within and beyond the discipline and how results from experimental studies of bias are generally misunderstood. I conclude by arguing that the current research tradition should be abandoned. (shrink)

Corporate social responsibility is widely established by companies that aim to contribute to society and minimize their negative impact on the environment. In CSR research, employees’ reactions to CSR have extensively been researched. Social identity theory is often used as a theoretical background to explain the relationship between CSR and employee-related outcomes, but until now, a sound empirical examination is lacking, and causality remains unclear. CSR can unfold its effect mainly because of three theoretically important aspects of CSR (...) initiatives, which increase identification, i.e., distinctiveness, prestige, and salience of the out-group. This study examines how far identification can explain the effect of CSR on employees. In an experimental vignette study, CSR was manipulated in three degrees to examine its effects on job satisfaction, organizational commitment, and organizational citizenship behavior. In the vignettes, information on distinctiveness, prestige, and salience of the out-group were presented. Regression analyses showed that CSR significantly predicted commitment and job satisfaction, but not OCB. We found mediation effects of CSR on commitment, job satisfaction, and OCB through identification, but the effect of CSR on identification explained only little variance which indicates additional underlying mechanisms. The applicability of social identity theory for explaining CSR is discussed. Moreover, we discuss further explaining mechanisms. (shrink)

Biology is seen not merely as a privileged oppressor of women but as a co-victim of masculinist social assumptions. We see feminist critique as one of the normative controls that any scientist must perform whenever analyzing data, and we seek to demonstrate what has happened when this control has not been utilized. Narratives of fertilization and sex determination traditionally have been modeled on the cultural patterns of male/female interaction, leading to gender associations being placed on cells and their components. (...) We also find that when gender biases are controlled, new perceptions of these intracellular and extracellular relationships emerge. (shrink)

Computational simulations have provided evidence that the use of linguistic cues as group markers plays an important role in the development of linguistic diversity shortcite. Other simulations, however, have contradicted these findings. Similar disagreements exist in sociolinguistics. This paper describes an experimental study in which participants played an anonymous economic game using an instant-messenger-style program and an artificial ‘alien language’. The competitiveness of the game and the frequency with which players interacted were manipulated. Given frequent enough interaction with (...) team-mates, players were able to use linguistic cues to identify themselves. In the most competitive condition, this led to divergence in the language, which did not occur in other conditions. This suggests that both frequency of interaction and a pressure to use language to mark identity play a significant role in encouraging linguistic divergence over short periods, but that neither is suffi cient on its own.

Since Darwin, the idea of psychological continuity between humans and other animals has dominated theory and research in investigating the minds of other species. Indeed, the field of comparative psychology was founded on two assumptions. First, it was assumed that introspection could provide humans with reliable knowledge about the causal connection between specific mental states and specific behaviors. Second, it was assumed that in those cases in which other species exhibited behaviors similar to our own, similar psychological causes were at (...) work. In this paper. we show how this argument by analogy is flowed with respect to the case of second-order mental states. As a test case, we focus on the question of how other species conceive of visual attention, and in particular whether chimpanzees interpret seeing as a mentalistic event involving internal states of perception, attention, and belief. We conclude that chimpanzees do not reason about seeing in this manner, and indeed, there is considerable reason to suppose that they do not harbor representations of mental states in general. We propose a reinterpretation model in which the majority of the rich social behaviors that humans and other primates share in common emerged long before the human lineage evolved the psychological means of interpreting those behaviors in mentalistic terms. Although humans, chimpanzees, and most other species may be said to possess mental states, humans alone may have evolved a cognitive specialization for reasoning about such states. (shrink)

This study uses a quasi-experimental design to investigate what happens to individual socially responsible attitudes when they are exposed to group dynamics. Findings show that group engagement increases individual attitudes toward social responsibility. We also found that individuals with low attitudes toward social responsibility are more likely to change their opinions when group members show more positive attitudes toward social responsibility. Conversely, individuals with high attitudes do not change much, independent of group (...) characteristics. To better analyze the effect of group dynamics, the study proposes to split social responsibility into relative and absolute components. Findings show that relative social responsibility is correlated with but different from absolute social responsibility although the latter is more susceptible than the former to group dynamics.

In this paper, we use the risk apportionment technique of Eeckhoudt, Rey and Schlesinger (2007) to study higher order risk preferences for others’ health as well as ex-ante and ex-post inequality preferences for social risky distributions, and their interaction. In an experiment on a sample of university students acting as impartial spectators, we observe risk aversion towards social health losses and a dislike of ex-ante inequality. In addition, evidence for ex-post inequality seeking is much weaker than evidence for (...) ex-ante inequality aversion. Because ex-ante inequality aversion is unrelated to risk aversion, we conclude that simple forms of utilitarianism are not relevant for individual judgment of social risk over health. Last, our investigation of precautionary distribution, which would occur when one particular group in the society suffers from background health risk, shows substantial polarization of preferences.

Social identity is embedded in social structures, generated by various social processes, and has multiple dimensions. We report findings from a laboratory experiment eliciting two-dimensional social identities: a horizontal identity determined either randomly or by preferences and a vertical identity defined by income status and determined either by luck or performance. We also vary income gaps between vertical identity groups. Participants make redistributive allocation decisions between two beneficiaries differing in identity attributes. We find robust evidence of (...) in-group favoritism and that both the identity distance between the allocator and the in-group recipient and income gaps influence the degree of in-group favoritism.

The study examined the effectiveness of group investigation versus lecture-based instruction on students’ concept mastery and transferability in social studies learning. The researcher used an experimental design to randomly assign 116 eighth-grade students into control and experimental groups. The control and experimental group had 58 students, respectively. The researcher exposed the control group to lecture-based instruction through an oral presentation led by an instructor. On the other hand, students in the group investigation (...) approach were grouped into groups of 6 and asked to investigate, think, discuss, and share their ideas on the topic with the class of 56 students. As the researcher hypothesized, the experimental group that the instructor exposed to the group investigation method that required learners to be active, plan, discuss, question, investigate a given topic, think, inquire, and present their findings to the class significantly outperformed the control group where learners mainly were passive listeners, on both concept mastery and transferability. Therefore, a significant difference exists between the lecture-based approach and group investigation towards promoting concept mastery and transfer performance among eighth-grade students. Based on the study results, the researcher recommends that eighth-grade social studies instructors adopt the group investigation method since it keeps learners active and also enhances transfer and concept mastery.

Orphans and vulnerable children fall under the category of children who are at risk of exposure to more stressful circumstances and receive less social assistance compared to other children. This study aims to investigate the impact of group counseling based on social intervention and psychological therapy on social support and the perceived stress growth of orphans and vulnerable children. In one special educational needs school in Nanning, China, the SSGPC was developed and implemented. Using the (...) class='Hi'>social support and post-stress growth scales, the researchers investigated the effects of SSGPC on orphans and vulnerable children. Twenty-seven orphans and vulnerable children between the ages of nine and 12 were arbitrarily assigned to the experimental and control groups. A pre-test post-test method of quasi-experimental design was applied, with 13 participants in the experimental group and 14 in the control group. The results revealed that the intervention group had significantly higher scores for social support and post-stress growth than the control group. The SSGPC had significantly improved the levels of social support for orphans. The findings indicated that the SSGPC provided an effective way to improve social support and post-stress growth of orphans and vulnerable children. (shrink)

Most decision-making research in economics focuses on individual decisions. Yet, we know, from psychological research in particular, that individual preferences can be sensitive to social pressures. In this paper, we study the impact of a group environment on individual preferences for risky and ambiguous prospects. In our experiment, each participant was invited to make a series of lottery-choice decisions in two different conditions. In the Alone condition, individuals made private choices, whereas in the Group condition, individuals belonged (...) to a three-person group and group members’ choices were aggregated according to either a majority or unanimity rule. This design allows us to study the impact of a group environment on individuals’ attitude towards both risky and ambiguous prospects, while controlling for the decision rule used in the group. Our experimental results show that when individuals are in the Group condition, they tend to be less risk averse and more ambiguity averse than when they are not part of a group. Our experiment also suggests that the decision rule matters as it shows that these two trends tend to be stronger when the group implements a unanimity rule. Specifically, we found that individuals who belong to a group implementing a unanimity rule are significantly less risk averse than individuals who belong to a group that relies on the majority rule. We obtained a similar—but non-significant—result under ambiguity. (shrink)

Integrating different perspectives is a sophisticated strategy for developing constructive interactions in collaborative problem solving. However, cognitive aspects such as individuals’ knowledge and bias often obscure group consensus and produce conflict. This study investigated collaborative problem solving, focusing on a group member interacting with another member having a different perspective. It was predicted that mavericks might mitigate disadvantages and facilitate perspective taking during problem solving. Thus, 344 university students participated in two laboratory-based experiments by engaging in a simple (...) rule-discovery task that raised conflicts among perspectives. They interacted with virtual partners whose conversations were controlled by multiple conversational agents. Results show that when participants interacted with a maverick during the task, they were able to take others’ perspectives and integrate different perspectives to solve the problem. Moreover, when participants interacted in groups with a positive mood, groups with a maverick outperformed groups having several perspectives. (shrink)

Cesario provides a compelling critique of the use of experimental social psychology to explain real-world group disparities. We concur with his targeted critique and extend “the problem of missing information” to another common measures of bias. We disagree with Cesario's broader argument that the entire enterprise be abandoned, suggesting instead targeted utilization. Finally, we question whether the critique is appropriately directed at experimental social psychologists.

This monograph investigates the collaborative creation of scientific knowledge in research groups. To do so, I combine philosophical analysis with a first-hand comparative case study of two research groups in experimental science. Qualitative data are gained through observation and interviews, and I combine empirical insights with existing approaches to knowledge creation in philosophy of science and social epistemology. -/- On the basis of my empirically-grounded analysis I make several conceptual contributions. I study scientific collaboration as the interaction of (...) scientists within research groups. Thereby, I argue that research groups and their role in scientific practice deserve more philosophical attention than they have hitherto received. In contemporary natural science, research groups are key to the formulation and corroboration of scientific knowledge claims prior to their publication. Specifically, I suggest epistemic difference and the porosity of social structure as two conceptual leitmotifs in the study of group collaboration. With epistemic difference, I emphasize the value of socio-cognitive heterogeneity in group collaboration. With porosity, I underline the fact that a research group as social structure does not entirely contain the inter-individual efforts necessary to formulate and corroborate knowledge claims. -/- In my analysis of research groups, I focus on the division of epistemic labor among group members. Through their complementary collaborative efforts single scientists engage in relations of mutual epistemic dependence. To deepen philosophy’s understanding of scientific practice in its diversity, a distinction should be made between opaque and translucent epistemic dependence. While opaque epistemic dependence involves asymmetries in expertise, translucent epistemic dependence does not. As epistemic dependence is facilitated by trust, I investigate the dynamics of epistemic trust in group collaboration. Trust among collaborating scientists is inherently incomplete, and I show that scientists make use of diverse strategies to increase and to supplement personal trust. Based on my reflections on trust and dependence, I give an account of the relation between individual knowing and collaboratively created knowledge in research groups. Together these investigations contribute to the discussion of philosophical methodology in the study of scientific practice and promote the use of empirical methods. (shrink)

Experimental research by social and cognitive psychologists has established that cooperative groups solve a wide range of problems better than individuals. Cooperative problem solving groups of scientific researchers, auditors, financial analysts, air crash investigators, and forensic art experts are increasingly important in our complex and interdependent society. This comprehensive textbook--the first of its kind in decades--presents important theories and experimental research about group problem solving. The book focuses on tasks that have demonstrably correct solutions within mathematical, (...) logical, scientific, or verbal systems, including algebra problems, analogies, vocabulary, and logical reasoning problems.The book explores basic concepts in group problem solving, social combination models, group memory, group ability and world knowledge tasks, rule induction problems, letters-to-numbers problems, evidence for positive group-to-individual transfer, and social choice theory. The conclusion proposes ten generalizations that are supported by the theory and research on group problem solving. Group Problem Solving is an essential resource for decision-making research in social and cognitive psychology, but also extremely relevant to multidisciplinary and multicultural problem-solving teams in organizational behavior, business administration, management, and behavioral economics.

Currently there is an unattached link between the study of social influence in experimental psychology and bad faith in the existential philosophy of Jean-Paul Sartre. The methods of psychology and philosophy differ significantly and can be integrated into a unified whole to provide enhanced insight into a topic of investigation compared to what can be achieved separately in each of these disciplines. The goal of this paper is to review the social influence literature with the aim of (...) expositing, integrating and synthesising the findings with Sartre’s analysis of bad faith and authenticity. As a result, this paper aims to uncover the scientific findings that provide clarification to the findings of bad faith in Sartre’s existential philosophy. Precisely, this paper will provide concrete and descriptive empirical examples of the experimental causes and conditions that appear to be identified by participants as a reason to act in bad faith. Specifically, this paper provides evidence that bad faith appears to arise when an individual believes she should be accurate or affiliated with the group. An analysis of the concepts that are necessary to understand bad faith will also be reviewed to uncover the arguments that provide clarification to understanding conformity found in the social influence literature. This paper will benefit both psychologists and philosophers by bridging these two fields of investigation. Further work with the integration of these findings into existential psychotherapy is encouraged and described throughout. (shrink)

Experimental philosophy has been engaged in many fields of philosophy and has tried to challenge philosophy from a new horizon. In this article, I have tried to examine what the role of sciences are in altering people’s intuition about free will. Could science educate people’s philosophical intuitions? If yes, should we still rely on their intuition as a rational instrument for our philosophical questions? Do science plus cultural and social differences effect on folks’ view? In this cross-cultural research, (...) the emphasis is mostly on recent breakthroughs on neuroscience and its impact on people’s perspective to free will. I have asked some questions about free will and determinism from two groups of Iranian and European participants. The results of this study revealed an interesting amount of cross-cultural similarities. The findings showed that people have a relatively independent view to free will and determinism. It seems that manipulating laymen’s opinion by either the idea of scientific determinism or living under pressure and challenging social conditions cannot touch their perspective. I tried to indicate that the techniques of experimental philosophy and the data offered might help us to learn more and more about the psychological processes, in the mind of the folks, that engender philosophical problems.

Evolutionary economics often focuses on the comparison between economic competition and the process of natural selection to select the fitter members of a given population. But that neglects the other "half" of an evolutionary process, the mechanism for the generation of new possibilities that is key to dynamic efficiency. My topic is the process of parallel experimentation which I take to be a process of multiple experiments running concurrently with some form of common goal, with some semi-isolation between the experiments, (...) with benchmarking comparisons made between the experiments, and with the "migration" of discoveries between experiments wherever possible to ratchet up the performance of the group. The thesis is that parallel experimentation is a fundamental dynamic efficiency scheme to enhance and accelerate variation, innovation, and learning in contexts of genuine uncertainty or known ignorance. Within evolutionary biology, this type of parallel experimentation scheme was developed in Sewall Wright's shifting balance theory of evolution. It addressed the rather neglected topic of how a population on a low fitness peak might eventually be able to go "downhill" against selective pressures, traverse a valley of low fitness, and then ascend a higher fitness peak. The theme of parallel experimentation is used to recast and pull together dynamic and pluralistic theories in economics, political theory, philosophy of science, and social learning. (shrink)

There is strikingly little agreement across academic fields about the existence of free will, what experimental results show, and even what the term ‘free will’ means. In Lee and Harris’ “A Social Perspective on Debates About Free Will” the authors argue that group identities and their attendant social rewards are part of the problem. As they portray it, “different philosophical stances create social groups and inherent conflict, hindering interdisciplinary intellectual exploration on the question of free (...) will because people incorporate their support for a particular stance into their identity” (ms 1). Lee and Harris’ exciting approach downplays the stated basis of academic disagreements, instead looking to social phenomena to explain why academic theorists adopt their positions. In particular, they argue that (1) philosophical convictions are structured by social group membership, and (2) the way such groups operate disfavors alternative philosophical commitments on free will.

Economic small group research points to groups as more rational decision-makers in numerous economic situations. However, no attempts have been made to investigate whether groups are affected similarly by behavioral biases that are pervasive for individuals. If groups were also able to more effectively avoid these biases, the relevance of biases in actual economic contexts dominated by group decision-making might be questioned. We consider the case of anchoring as a prime example of a well-established, robust bias. Individual and (...) group biasedness in three economically relevant domains are compared: factual knowledge, probability estimates and price valuations. In contrast to previous anchoring studies, we find groups to successfully reduce, albeit not eliminate, anchoring in the factual knowledge domain. For the other two domains, groups and individuals are equally biased by external anchors. Group cooperation thus reduces biases for predominantly intellective tasks only, while no such reduction is achieved when judgmental aspects are involved. (shrink)

The emerging field of cognition and culture has had some success in explaining the spread of counterintuitive religious concepts around the world. However, researchers have been reluctant to extend its findings to explain the widespread occurrence of culturally counterintuitive ideas in general. This article develops a broader notion of social counterintuitiveness to include ideas that violate shared expectations of a group of people and argues that the notion of social counterintuitiveness is more crucial to explaining cultural success (...) of surprising ideas than the traditional notion of individual counterintuitiveness. Building on the context-based account of individual counterintuitiveness, the article also outlines how the once unorthodox cultural ideas become conventionalized over time only to be swept under the next wave of cultural innovation. By helping us peel away the layers of tradition that weave together the multilayered tapestry of culture, this account can be useful for understanding the development of cultural scaffolding that is needed to support the spread of maximally counterintuitive concepts such as widespread religious concepts of God and ghosts.

We report the results of an experiment on how individual risk taking clusters together when subjects are informed of peers’ previous risk taking decisions. Subjects are asked how much of their endowment they wish to allocate in a lottery in which there is a 50% chance the amount they invest will be tripled and a 50% chance their investment will be lost. We use a 2 × 2 factorial design varying: (i) whether the subjects initially observed high or low investment (...) social anchors, (ii) whether information about the investment decisions of other subjects in their social group is provided. We find strong evidence that individuals' risk taking decisions are malleable to that of their peers, which in turn leads to social clustering of risk taking. Social anchors shape initial risk taking, with mean investment then converging to a high level across treatments. (shrink)

Social epistemologists should be well-equipped to explain and evaluate the growing vulnerabilities associated with filter bubbles, echo chambers, and group polarization in social media. However, almost all social epistemology has been built for social contexts that involve merely a speaker-hearer dyad. Filter bubbles, echo chambers, and group polarization all presuppose much larger and more complex network structures. In this paper, we lay the groundwork for a properly social epistemology that gives the role and (...) structure of networks their due. In particular, we formally define epistemic constructs that quantify the structural epistemic position of each node within an interconnected network. We argue for the epistemic value of a structure that we call the (m,k)-observer. We then present empirical evidence that (m,k)-observers are rare in social media discussions of controversial topics, which suggests that people suffer from serious problems of epistemic vulnerability. We conclude by arguing that social epistemologists and computer scientists should work together to develop minimal interventions that improve the structure of epistemic networks. (shrink)

The social psychology of science is a compelling new area of study whose shape is still emerging. This erudite and innovative book outlines a theoretical and methodological agenda for this new field, and bridges the gap between the individually focused aspects of psychology and the sociological elements of science studies. Presenting a side of social psychology that, until now, has received almost no attention in the social sciences literature, this volume offers the first detailed and comprehensive study (...) of the social psychology of science, complete with a large number of empirical and theoretical examples. The volume's introductory section provides a detailed analysis of how modern social psychology might apply to the study of science. Chapters show how to analyze science in terms of social cognition, attribution theory, attitudes and attitude change, social motivation, social influence and social conformity, and intergroup relations, weaving extensive illustrations from the science studies literature into the theoretical analysis. The nature and role of experimentation are discussed, as are metaanalytic methods for summarizing the results of multiple studies. Ways to facilitate the generalization of causal inferences from experimental work are also examined. The book focuses on such topics as interactions among small groups of scientists, and the impact of social motivation, influence, and conformity on scientific work. Also covered are scientists' responses to ethical issues in research, differences in cognitive style distribution, creativity in research and development, and the sociologists's view of the social psychology of science and technology. In addition, the book provides two annotated bibliographies, one on the philosophy of science and the other on social psychology, to guide readers in both disciplines to salient recent works. Valuable to the entire science studies community, this text will be of special interest to philosophers, sociologists, psychologists, and historians of science interested in the nature of knowledge development in science. Because of its novel application of social psychological theories and methods, this book will be useful as a primary text or a secondary text in courses on science studies in psychology, sociology, or philosophy departments.

Today, the linguistic approach offers us an irreplaceable method for the direct study of the constitutive processes of social phenomena (A. Delobelle, 1981). In fact, each social phenomenon is basically inhabited or interpreted by language. It is language processes that give its ramifications to the social and form disstinct sub-groups in it. This is why, when these processes are observed in their formal dynamics, outside their vehiculated “contents,” it is as though we find ourselves faced with the (...) very functioning of the social: as though we have in it a typically experimental terrain for the direct study of social phenomena.

Social network structure has been argued to shape the structure of languages, as well as affect the spread of innovations and the formation of conventions in the community. Specifically, theoretical and computational models of language change predict that sparsely connected communities develop more systematic languages, while tightly knit communities can maintain high levels of linguistic complexity and variability. However, the role of social network structure in the cultural evolution of languages has never been tested experimentally. Here, we present (...) results from a behavioral group communication study, in which we examined the formation of new languages created in the lab by micro‐societies that varied in their network structure. We contrasted three types of social networks: fully connected, small‐world, and scale‐free. We examined the artificial languages created by these different networks with respect to their linguistic structure, communicative success, stability, and convergence. Results did not reveal any effect of network structure for any measure, with all languages becoming similarly more systematic, more accurate, more stable, and more shared over time. At the same time, small‐world networks showed the greatest variation in their convergence, stabilization, and emerging structure patterns, indicating that network structure can influence the community's susceptibility to random linguistic changes (i.e., drift).

Previous research has discovered a curious phenomenon: groups cooperate less than individuals in a deterministic prisoner’s dilemma game, but cooperate more than individuals when uncertainty is introduced into the game. We conducted two studies to examine three possible processes that might drive groups to be more cooperative than individuals in reducing risks: group risk concern, group cooperation expectation, and pressure to conform to social norms. We found that ex post guilt aversion and ex-post blame avoidance cause (...) class='Hi'>group members to be more risk concerned than individuals under uncertainty. These concerns drive groups to choose the cooperation (and risk-reduction) strategy more frequently than individuals. Groups also have higher cooperation expectations for their corresponding groups than individuals have for their corresponding individuals. We found no evidence of pressure to conform to social norms driving groups to be more cooperative than individuals. (shrink)

Concerning the ubiquity of social media, this research tried to examine the impacts of using Telegram on Iranian EFL learners’ foreign language motivation, foreign language anxiety, and attitude toward learning. To achieve these purposes, 60 Iranian EFL learners at the intermediate level were selected and randomly divided into two groups: experimental and control. After that, both groups were pretested on motivation and anxiety variables. After pretesting, the participants in the experimental class received treatmentviausing the Telegram application, and (...) the control students were trained traditionally without using any social media. After an 18-session instruction, a post-test of motivation and a post-test of anxiety were given to both groups, and also an attitude questionnaire was distributed among the experimental group to inspect their attitudes toward the Telegram application in language learning. The results of using two one-way ANCOVA tests showed significant differences between the post-tests of the control and experimental groups in favor of the experimental group. The findings demonstrated that using the Telegram application increased the motivation of the experimental group and decreased their level of foreign language anxiety. Also, the results of one sample t-test showed that the participants of the experimental group held positive attitudes toward using the Telegram application in English language learning. The implications of this research can encourage both teachers and learners to use social media-based instruments in English teaching and learning. (shrink)

Capacities for abstract thinking and problem‐solving are central to human cognition. Processes of abstraction allow the transfer of experiences and knowledge between contexts helping us make informed decisions in new or changing contexts. While we are often inclined to relate such reasoning capacities to individual minds and brains, they may in fact be contingent on human‐specific modes of collaboration, dialogue, and shared attention. In an experimental study, we test the hypothesis that social interaction enhances cognitive processes of rule‐induction, (...) which in turn improves problem‐solving performance. Through three sessions of increasing complexity, individuals and groups were presented with a problem‐solving task requiring them to categorize a set of visual stimuli. To assess the character of participants’ problem representations, after each training session, they were presented with a transfer task involving stimuli that differed in appearance, but shared relations among features with the training set. Besides, we compared participants’ categorization behaviors to simulated agents relying on exemplar learning. We found that groups performed superior to individuals and agents in the training sessions and were more likely to correctly generalize their observations in the transfer phase, especially in the high complexity session, suggesting that groups more effectively induced underlying categorization rules from the stimuli than individuals and agents. Crucially, variation in performance among groups was predicted by semantic diversity in members’ dialogical contributions, suggesting a link between social interaction, cognitive diversity, and abstraction.

We often remember in groups, yet research on collaborative recall finds “collaborative inhibition”: Recalling with others has costs compared to recalling alone. In related paradigms, remembering with others introduces errors into recall. We compared costs and benefits of two collaboration procedures—turn taking and consensus. First, 135 individuals learned a word list and recalled it alone (Recall 1). Then, 45 participants in three-member groups took turns to recall, 45 participants in three-member groups reached a consensus, and 45 participants recalled alone but (...) were analysed as three-member nominal groups (Recall 2). Finally, all participants recalled alone (Recall 3). Both turn-taking and consensus groups demonstrated the usual pattern of costs during collaboration and benefits after collaboration in terms of recall completeness. However, consensus groups, and not turn-taking groups, demonstrated clear benefits in terms of recall accuracy, both during and after collaboration. Consensus groups engaged in beneficial group source-monitoring processes. Our findings challenge assumptions about the negative consequences of social remembering. (shrink)

This article describes the historical abandonment of the distinctive conception of the social dimensions of cognition, emotion and behavior embraced by American social psychologists in the early decades of the twentieth century. It is suggested that part of the reason why the original conception of the social was abandoned by American psychologists was because of its association with theories of the “group mind,” the apparent threat it posed to cherished principles of rationality and autonomy, and the (...) impoverished conception of the social inherited from European crowd theorists that came to inform the experimental study of social groups. It is suggested that while these factors partly explain the neglect of the social in American social psychology, none represent particularly good reasons for abandoning the original conception of the social. Consequently there are in principle no impediments to the revival of the theoretical and experimental study of the social dimensions of cognition, emotion and behavior in contemporary American social psychology.
