Agent-based modeling: a new approach for theory building in social psychology.

Most social and psychological phenomena occur not as the result of isolated decisions by individuals but rather as the result of repeated interactions between multiple individuals over time. Yet the theory-building and modeling techniques most commonly used in social psychology are less than ideal for understanding such dynamic and interactive processes. This article describes an alternative approach to theory building, agent-based modeling (ABM), which involves simulation of large numbers of autonomous agents that interact with each other and with a simulated environment and the observation of emergent patterns from their interactions. The authors believe that the ABM approach is better able than prevailing approaches in the field, variable-based modeling (VBM) techniques such as causal modeling, to capture types of complex, dynamic, interactive processes so important in the social world. The article elaborates several important contrasts between ABM and VBM and offers specific recommendations for learning more and applying the ABM approach.     

Promoting a culture of innovation: BJSP and the emergence of new paradigms in social psychology

In this paper, I start by describing the role played by British Journal of Social Psychology (BJSP) in nurturing two important new paradigms in social psychology - the social identity approach and discourse psychology. I then consider the forces in contemporary academia, in general, and psychology, in particular, that militate against innovation. I conclude by suggesting some ways in which individual social psychologists and our journals, particularly BJSP, can contribute to the development of an innovative and intellectually dynamic discipline.     

The probability of war in then-crises problem: Modeling new alternatives to Wright's solution

In hisStudy of War, Q. Wright considered a model for the probability of warP during a period ofn crises, and proposed the equationP=1–(1–p) ⁿ , wherep is the probability of war escalating at each individual crisis. This probability measure was formally derived recently by Cioffi-Revilla (1987), using the general theory of political reliability and an interpretation of the n-crises problem as a branching process. Two new, alternate solutions are presented here, one using D. Bernoulli's St. Petersburg Paradox as an analogue, the other based on the logic of conditional probabilities. Analysis shows that, while Wright's solution is robust with regard to the general overall behavior ofp andn, some significant qualitative and quantitative differences emerge from the alternative solutions. In particular,P converges to 1 only in a special case (Wright's) and not generally.C.C.-R. acknowledges support provided by the Merriam Laboratory for Analytic Political Research, the Research Board of the University of Illinois, and grant SES-84-00877 from the U.S. National Science Foundation.     

Getting too close: A problem and possible solution in social science PhD supervision

The duties of PhD supervisor involve combining the dimensions of intellectual critic and guide to doctoral students, whilst at the same time offering the latter pastoral care, tasks which occur under conditions of increasing difficulty. The combination of these duties is depicted, and the pastoral dimension of supervision is portrayed as harbouring the potential, unless skilfully handled, for supervisors to become too emotionally involved with their students. The costs of this over-involvement are subsequently identified and a solution is proposed, namely that training programmes for PhD supervisors should contain a pastoral skills component.     

Finding "meaning" in psychology: a lay theories approach to self-regulation, social perception, and social development

Much of psychology focuses on universal principles of thought and action. Although an extremely productive pursuit, this approach, by describing only the "average person," risks describing no one in particular. This article discusses an alternate approach that complements interests in universal principles with analyses of the unique psychological meaning that individuals find in their experiences and interactions. Rooted in research on social cognition, this approach examines how people's lay theories about the stability or malleability of human attributes alter the meaning they give to basic psychological processes such as self-regulation and social perception. Following a review of research on this lay theories perspective in the field of social psychology, the implications of analyzing psychological meaning for other fields such as developmental, cultural, and personality psychology are discussed.     

Negative priming between pictures and words in a selective attention task: Evidence for semantic processing of ignored stimuli

This study examined the processing of ignored pictures and words when attention was directed to a different picture or word. Previous work by Tipper (1985) demonstrated that the priming effect of an ignored picture on a subsequent categorically related picture is inhibitory. This effect was termednegative priming. Tipper concluded that ignored pictures achieved abstract categorical levels of internal representation, and that these representations were inhibited during selection of a simultaneously presented picture. This conclusion, however, was premature. Observation of the figures used by Tipper suggests that objects within a category have greater structural similarity than do objects in different categories. The negative priming effect could therefore be at a structural level of representation. The present study examined priming across symbolic domains (pictures and words) where there was no structural relationship between objects. Negative priming was again observed and was equivalent to the negative priming observed within symbolic domain. These data suggest that ignored drawings and words do achieve abstract categorical levels of representation, and that the mechanisms underlying negative priming operate at, or beyond, this level.     

Independent component analysis as a rotation method: A very different solution to Thurstone's box problem

In this paper we consider the well‐known Thurstone box problem in exploratory factor analysis. Initial loadings and components are extracted using principal component analysis. Rotating the components towards independence rather than rotating the loadings towards simplicity allows one to accurately recover the dimensions of each box and also produce simple loadings. It is shown how this may be done using an appropriate rotation criterion and a general rotation algorithm. Methods from independent component analysis are used, and this paper may be viewed as an introduction to independent component analysis from the perspective of factor analysis.     

From intrapsychic to ecological theories in social psychology: Outlines of a functional theory approach

Social psychology is facing a major developmental task, which is not primarily one of achieving larger data samples and stricter significance testing. What is needed, rather, is an improvement in logic of science and powerful theorizing. The starting point of this article is a critical appraisal that the intrapsychic concepts (motives, attitudes, and explicit and implicit goals) that are the major focus of social–psychological theories lack in explanatory power because they are too close to the effects (actions, judgments, and decisions) they are intended to explain. To overcome this apparent weakness (compared with neuroscience or genetics), it is proposed that more powerful theories should relate social cognition and behavior to more distant variables in the environment. A functional analysis reveals that intrapsychic processes are multiply predetermined by extrapsychic, environmental constraints. The theoretical value and fertility of the proposed ecological functionalism are illustrated with reference to three areas of empirical research: sampling approaches to understanding biases in judgment and decision making; strategic influences on priming effects within a functional analysis of adaptive behavior; and the impact of verbal and symbolic communication constraints on the construction of attributions, stereotypes, and culture.

Towards a balanced social psychology: causes, consequences, and cures for the problem-seeking approach to social behavior and cognition

Mainstream social psychology focuses on how people characteristically violate norms of action through social misbehaviors such as conformity with false majority judgments, destructive obedience, and failures to help those in need. Likewise, they are seen to violate norms of reasoning through cognitive errors such as misuse of social information, self-enhancement, and an over-readiness to attribute dispositional characteristics. The causes of this negative research emphasis include the apparent informativeness of norm violation, the status of good behavior and judgment as unconfirmable null hypotheses, and the allure of counter-intuitive findings. The shortcomings of this orientation include frequently erroneous imputations of error, findings of mutually contradictory errors, incoherent interpretations of error, an inability to explain the sources of behavioral or cognitive achievement, and the inhibition of generalized theory. Possible remedies include increased attention to the complete range of behavior and judgmental accomplishment, analytic reforms emphasizing effect sizes and Bayesian inference, and a theoretical paradigm able to account for both the sources of accomplishment and of error. A more balanced social psychology would yield not only a more positive view of human nature, but also an improved understanding of the bases of good behavior and accurate judgment, coherent explanations of occasional lapses, and theoretically grounded suggestions for improvement.     

Discourse, action, rhetoric: from a perception to an action paradigm in social psychology

This article provides a personal account of how discursive social psychology has been used to understand social and political change in South Africa and to reflect on the strengths and limitations of the approach. While celebrating the shift from the perception paradigm to the genuinely social constructionist focus on discursive interaction, the article also argues for an expanded focus on embodied action.     

Islam as a new social actor in Italian cities: mosque controversies as sites of inclusion and separation

Most Muslim immigrants oscillate in the public sphere between three levels in the public sphere: the local, the national and the transnational. While the national and transnational levels continue to be marked by a strong degree of conflictuality, it is at the local level where new integration strategies are implemented and ‘social capital’ is acquired. The comparison between two similar debates over the construction of a mosque in the Italian cities of Bologna and Florence with opposite outcomes reveals the importance of the local dimension in the construction of a national Islam and the significance of appropriate participatory tools in the inclusion of Muslims in the local public sphere. In particular, the article highlights the link between the legitimacy of Islam in the fabric of the city and the degree of openness of the Islamic community. It also illustrates how overcoming the reluctance and fear of different actors can allow citizens to assimilate the idea of ‘a mosque in the city’ and not just of ‘a mosque for Muslims’. The article describes how the use of appropriate tools, particularly of participatory decision-making, has made it easier for marginalised or politically excluded individuals to take steps towards full citizenship and for the Muslim community to emerge as a legitimate social actor in the local public sphere.     

Race as biology is fiction, racism as a social problem is real: Anthropological and historical perspectives on the social construction of race

Racialized science seeks to explain human population differences in health, intelligence, education, and wealth as the consequence of immutable, biologically based differences between "racial" groups. Recent advances in the sequencing of the human genome and in an understanding of biological correlates of behavior have fueled racialized science, despite evidence that racial groups are not genetically discrete, reliably measured, or scientifically meaningful. Yet even these counterarguments often fail to take into account the origin and history of the idea of race. This article reviews the origins of the concept of race, placing the contemporary discussion of racial differences in an anthropological and historical context.     

社交焦虑大学生情绪调节灵活性：情绪内容对策略选择和使用的影响

尽管社交焦虑个体被认为存在情绪调节灵活性的不足,但至今尚不清楚这种不足究竟在于难以灵活选择策略,还是难以灵活使用策略,抑或二者兼有？对此,本研究采用情绪调节策略选择任务考察了37名高社交焦虑大学生和29名低社交焦虑大学生在面对社交-非社交情绪图片时对认知重评-回避策略的选择模式和使用效果。结果发现：在面对社交情绪图片时,高社交焦虑被试比低社交焦虑被试更少选择认知重评,而更多选择回避;在面对非社交情绪图片时,两组被试对两种策略的选择模式无显著差异。同时,无论面对社交还是非社交情绪图片,两组被试对两种策略的使用效果也无显著差异。以上结果表明,相比低社交焦虑个体,高社交焦虑个体只有在面对社交情绪刺激时才存在情绪调节灵活性的不足,且这种不足主要在于难以灵活选择策略,而非难以灵活使用策略。     

Categorization and individuation in the cross-race recognition deficit: Toward a solution to an insidious problem

Recent theory and evidence suggest that the Cross-Race Effect (better recognition for same-race (SR) faces than for cross-race (CR) faces) is due to social-cognitive processes of categorization of out-group members, causing perceivers to attend to category-specifying information of CR faces at the expense of individuating information. Three experiments seek to extend this social-cognitive explanation of the CRE by investigating the extent to which the Cross-Race Effect can be reduced by inducing perceivers to individuate rather than categorize CR faces. In all three experiments, participants who received warning of the Cross-Race Effect prior to encoding, and instructions to individuate out-group members, showed no CRE. Experiment 2 suggests that this elimination of the CRE was not due merely to increased motivation to process all stimuli. This is one of few empirical displays of an elimination of the CRE outside of visual training. Moreover, these results are congenial with Levin’s (2000) feature-selection model, which suggests that the CRE is due to differential social cognitions about in-group and out-group members, rather than to differences in perceptual expertise. By eliciting individuation of out-group members at encoding, the CRE can be eliminated.     

A solution to a problem raised in Luce and Marley (2005)

Luce and Marley [2005. Ranked additive utility representations of gambles: Old and new axiomatizations. Journal of Risk and Uncertainty, 30, 21-62] examined various relations between mathematical forms for the utility of joint receipt ⊕ of gambles and for the utility of uncertain gambles. Their assumptions lead to a bisymmetry functional equation which, when the gambles are ranked, is defined on a restricted domain. Maksa [1999. Solution of generalized bisymmetry type equations without surjectivity. Aequationes Mathematicae, 57, 50-74] solved the general case and Kocsis [2007. A bisymmetry equation on restricted domain. Aequationes Mathematicae, 73, 280-284] presents the solution for the ranked case. The latter solution allows us to solve open problem 5 in Luce and Marley (2005) by showing that the assumptions of their Theorem 19 for an order-preserving ranked additive utility (RAU) representation U imply that U is a ranked weighted utility (RWU) representation that is additive over ⊕.
