Social Categorization and Stereotyping: How Social Categorization Biases Person Perception and Face Memory

The current article offers a brief history of research and theory related to social categorization and stereotyping. We begin by outlining research focusing on category selection, category activation, and category application. We then discuss the consequences of social categorization, noting that one of the most important and ubiquitous effects of social categorization is homogenization or assimilation. We then extend this research related to the assimilative consequences of social categorization to the realm of face memory. Specifically, we introduce the Categorization‐Individuation Model (see also Hugenberg et al., forthcoming) as a new model of the Cross‐Race Effect, or the difficulty many perceivers have in recognizing members of other racial groups. The Categorization‐Individuation Model argues that the Cross‐Race Effect is due to the tendency to categorize out‐group members but individuate in‐group members. Finally, we summarize the extant research in support of this new model of person memory and close by discussing the current state of, and potential future directions for, social categorization research.     

Social Categorization in Intergroup Contexts: Three Kinds of Self‐Categorization

In reviewing self‐categorization theory and the literature upon which it is based, we conclude that individuals' attempts to form social categories could lead to three kinds of self‐categorization. We label them intergroup categorization, ingroup categorization, and outgroup categorization. We review literature supporting these three types and argue that they can help to explain and organize the existing evidence. Moreover, we conclude that distinguishing these three kinds of self‐categorization lead to novel predictions regarding social identity, social cognition, and groups. We offer some of those predictions by discussing their potential causes (building from optimal distinctiveness and security seeking literatures) and implications (on topics including prototype complexity, self‐stereotyping, stereotype formation, intergroup behavior, dual identity, conformity, and the psychological implications of perceiving uncategorized collections of people). This paper offers a platform from which to build theoretical and empirical advances in social identity, social cognition, and intergroup relations.     

Social Categorization and Stimulus Equivalence

Northern Irish Protestant subjects, Northern Irish Catholic subjects, and English Protestant subjects were taught a series of conditional discriminations using a matching-to-sample procedure. In the presence of Northern Irish Catholic names, subjects were trained to select three-letter nonsense syllables, and in the presence of the nonsense syllables subjects were trained to select Northern Irish Protestant symbols. Subjects were then tested to determine whether the Protestant symbols and Catholic names had become related through symmetry and transitivity. A generalization test was employed to allow for a preliminary investigation of the transfer of experimentally generated equivalence responding to untrained, socially loaded names. Preliminary findings suggest that prior social learning might interfere with equivalence responding. The relevance of these results to the theoretical interpretation of the equivalence phenomenon and to social attitude measurement in general is discussed.

     

Developmental and Social Determinants of Religious Social Categorization

The purpose of this study was to assess developmental and social determinants of the age at which children become aware that the social environment can be marked by categorization into religious groups and that those groups are associated with different religious beliefs. The results show that middle childhood is a critical period for this religious social categorization. Moreover, social factors play a role in the development. Religious categorization is likely to appear sooner in children attending heterogeneous schools than in those at homogeneous schools, and children from the minority religious group in the country understand religious categorization earlier than children from the majority group. However, no relation was found between the age at which religious categorization was understood and parents’ religious socialization practices. This study is of both theoretical and practical interest: It complements what is already known about gender, race, and ethnic categorization by integrating developmental and social frameworks, and it can serve as a guideline for educational programs.     

Social Categorization and Stereotyping In vivo: The VUCA Challenge

A substantial literature has examined the nature of social categorization, a fundamental process having important implications for a wide variety of social phenomena. The great majority of this research has focused on the role of particular, clearly identified social categories (e.g. race, nationality, etc.) while ignoring or holding constant other identity dimensions. This approach has afforded considerable leverage for understanding how salient social identities influence perception, judgment, and behavior. However, it leaves unaddressed many questions about how particular social identities become salient and how (and whether) identities might be inferred when category membership is ambiguous or unknown. Everyday social perception often occurs under conditions of volatility (dynamic contexts), uncertainty (missing information), complexity (multiple bases for categorization), and ambiguity (unclear meaning of available cues). As a consequence, research must address how these factors might qualify basic processes of social categorization. Available evidence is reviewed, and directions for future research are discussed.     

Integrating Social Information Processing and Attachment Style Research with Cognitive-behavioral Couple Therapy

The majority of the empirically validated interventions for relational distress focus primarily upon improving behavioral functioning, particularly couples’ communication patterns in conflict situations. However, although communication is highly predictive of relationship distress and later divorce, research on the effectiveness of premarital and marital interventions based on communication training has shown limited results. Therefore, although the skills-based approaches can be effective in treating relational discord and instability, they also often neglect another potentially powerful mechanism in the development of relational distress: the social cognitions and/or schemata regarding relationships that individuals carry into their marriages that stem from negative attachment experiences. Thus, this article describes how blending information gleaned from attachment style research with the body of literature addressing social information processing can enhance current methods for the treatment of relational discord. The existing research on adult romantic attachment styles is placed within a social-cognitive information processing framework and a case study demonstrating the utility of this approach with difficult couples is described.     

Blind to Object Changes: When Learning the Same Object at Different Levels of Categorization Modifies Its Perception

The perceptual features people extract from objects depend on how they typically categorize them. It is now commonly acknowledged that the human perceiver can interact with the objects of his or her world at different, hierarchically organized levels of categorization. People who have learned to categorize an object as general or specific may therefore perceive different features in this object. We report two experiments that examined the hypothesis that the nature of categorization (general vs. specific) can influence the perceived properties of an identical distal object.     

Social Categorization and the Influence of Drug Involvement on Drug Attitude Structures: Implications for Assessing Drug Use and Tolerance in the Workplace1

Theories of social categorization were used to generate hypotheses concerning the impact of drug involvement on the attitudes and knowledge structures that people use in making drug-related judgments. Data indicated that greater drug exposure tended to foster more complex knowledge structures for drugs and drug users as revealed by subjects’ perceptions of drug users, tolerance for drug use, and perceptions of drug seriousness. Basically, high drug involvement in terms of personal alcohol use and associating with illicit drug users was related to greater individuation of drug user types. Therefore, high-involved subjects, relative to low-involved individuals, were better able to discriminate between different drug user subtypes and drug user subtypes were more important to high-involved subjects when responding to drug-related survey items.     

A Social Categorization Explanation for Framing Effects in Nested Social Dilemmas

This study developed and tested the idea that social categorization processes help to explain framing effects in social dilemmas. Using self-categorization theory, we predicted that members of a collective would cooperate more when they faced homogeneous rather than heterogeneous resource frames. We manipulated the starting point of resources for the members of each of two subgroups making up a larger collective in a nested social dilemma. The resources of the subject's own subgroup started at the individual, subgroup, or collective level, and the resources of the opposing subgroup also started at the individual, subgroup, or collective level. The condition in which both subgroups' resources began at the collective level was similar to a traditional commons dilemma, while the condition in which both subgroups' resources began at the individual level was similar to a traditional public goods problem. The other conditions were new to this research domain. We found higher allocations to the collective account when the initial resource location was the same for both subgroups (versus different for each subgroup), even when this initial location was the subgroup or individual level. Whereas previous explanations for framing effects cannot account for these results, social categorization processes provide a parsimonious explanation for the observed pattern of allocations.     

Emergent Research in Social Vision: An Integrated Approach to the Determinants and Consequences of Social Categorization

Social categorization research has historically focused either on understanding how observers utilize visual cues in the face and body to make judgments of others or on understanding the downstream consequences that occur following social categorizations, but rarely both. Recently, however, research has evidenced a marked shift toward an integrated approach. Here, we provide a snapshot of social vision's contributions to the study of social categorization with a goal of illuminating the new and exciting directions afforded by an integrative approach. From this perspective, social categorizations are characterized not only as being informed by visual cues but also as being malleable, probabilistic, and contextualized. Moreover, the process of categorization itself can affect evaluative outcomes directly, independent of categorization. By exploring empirical evidence for this integrated approach to the determinants and consequences of social categorization, we show how the emerging field of social vision has revealed new insights into the nature of social categorization and by extension its implications for evaluations.     

社会分类的概念、线索及影响机制

作为社会认知的基本过程和重要途径,社会分类对预测刻板印象和群际感知、减少多元文化群体中的关系冲突、促进推理与决策以及指导社会关系推断等都有重要作用。人们进行社会分类的线索可以概括为明显线索和模糊线索、自然线索和社会线索以及静态线索和动态线索。社会分类会受到分类对象、情境和感知者等的作用,同时对人们认知、情绪、情感和行为等产生一系列影响。未来可以基于跨文化和发展视角探讨社会分类的线索偏向、潜在机制及立足本土文化检验社会分类的影响及干预策略。     

Popular and Rejected Children's Social Reasoning: Linking Social Status and Social Knowledge

The relationship between children's social status/sex and their moral judgments was examined. Sixty-four second- and third-grade children (33 boys, 31 girls) who were identified as popular or rejected by peer sociometric measures were shown pictures of children engaged in moral and second-order transgressions. The children were asked to rate each event on (a) the degree of seriousness for other and self, (b) the amount of punishment for other and self, and (c) rule alterability. The children were also asked for justification of the transgressions (why they thought the transgressions were wrong). The popular and rejected children differentiated between moral and second-order transgressions based upon criterion ratings and justifications. Differences emerged between the popular and the rejected children's ratings and justifications for moral transgressions, suggesting that children's moral judgments are related to social experiences associated with peer acceptance and rejection.     

Social Categorization and the Perception of Groups and Group Differences

The classification of human beings into distinct groups is a fundamental feature of social perception. Problematic phenomena, such as prejudice, discrimination, and intergroup conflict, are commonly traced back to categorization. We explore the minimal conditions under which categorization occurs and the basic mechanisms by which it affects cognition and behavior. We show that comparisons between groups are not necessary for categorization, reveal the conditions under which people overestimate or underestimate differences between groups, and sketch a model showing how social categorization gives rise to differences in the evaluation of ingroups and outgroups and to differences in the accuracy of judgments of ingroups and outgroups. We conclude with reflections on intergroup conflict and the role of moral judgment in such conflicts.

Interactions Between Mental Models Used in Categorization and Experiential Knowledge of Specific Cases

Three experiments investigated the relation between recognition of specific cases and categorization in a double-task paradigm that requires both types of information (Estes, 1986b). Results indicated that recognition and categorization were often affected differently by experimental variables. However, mental models used in categorization sometimes hindered development of experiential (case-based) knowledge, leading to lower levels of case recognition and suboptimal categorization performance. When mental models were complex or difficult to discover (non-salient), subjects often used experiential knowledge to classify into categories, resulting in dependence between categorization and recognition. A model of interactions between the two tasks is proposed that postulates two separate but interacting types of knowledge.     

Reactions to Social Categorization: Evaluating One Argument Against Affirmative Action1

One argument made against affirmative action is that it is undesirable or inappropriate to treat people on the basis of their group membership. The present study attempts to evaluate college students' opinions about this type of social categorization. Two variables were manipulated: type of social group (i.e., one based on race, gender, religion, sexual orientation, or college major), and the purpose of the categorization (to identify, to form a social group, to form a political group, or for affirmative action purposes). Results indicated that students were, in general, opposed to such social categorizations. The presence of interaction effects, however, suggests that opposition to affirmative action is not uniform across different target groups and is not based solely on objections to social categorization. Implications are discussed.     

信息线索变化条件下“性别/年龄”多重社会范畴的加工特性

选取40名老年人和38名年轻人做被试,以同时携带“年龄-性别”信息、体现着社会多重范畴的面孔作为靶子刺激,探究年龄或性别范畴中某一范畴发生变化时,多重社会范畴的类别化加工特性以及各个子范畴的类别化加工之间的相互关系。在此基础上进一步探讨了不同年龄（老年人-青年人）和性别（男性-女性）的认知者在面对社会多重范畴时相应的类别化加工过程是否存在差异。结果发现：当年龄或者性别中的某个社会范畴发生变化时,另一社会范畴的类别化加工未能达到完全自动化加工水平。具体地,年龄类别化加工的自动化程度高于性别;老年人对于面孔中的社会范畴信息的加工速度慢于年轻人;对老年面孔中的社会范畴信息进行加工需要耗费更多的认知资源;相对于老年女性而言,认知者更加偏好年轻女性的面孔。     

Social Structures and the Ontology of Social Groups

Social groups—like teams, committees, gender groups, and racial groups—play a central role in our lives and in philosophical inquiry. Here I develop and motivate a structuralist ontology of social groups centered on social structures (i.e., networks of relations that are constitutively dependent on social factors). The view delivers a picture that encompasses a diverse range of social groups, while maintaining important metaphysical and normative distinctions between groups of different kinds. It also meets the constraint that not every arbitrary collection of people is a social group. In addition, the framework provides resources for developing a broader structuralist view in social ontology.     

Object-Tool-Actor Interaction: Object Information Drives Intended Action

Tool use is typically explored via actor-tool interactions. However, the target-object (that which is being acted on) may influence perceived action possibilities and thereby guide action. Three different tool-target-object pairings were tested (Experiment 1). The hammering action demonstrated the greatest sensitivity and therefore subsequently used to further investigate target-object pairings. The hammer was removed as an option and instructions were provided using pictorial (Experiment 2), written (Experiment 3), and both pictorial and written formats (Experiment 4). The designed tool is chosen when available (Experiment 1) and when removed as a choice (i.e., the hammer), participants perform the same action associated with the designed tool (i.e., hammering) regardless of instruction method (Experiments 2, 3, and 4).
