Under what conditions will a bystander intervene to try to stop a violent attack by one person on another? it is generally believed that the greater the size of the crowd of bystanders, the less the chance that any of them will intervene. A complementary model is that social identity is critical as an explanatory variable. For example, when the bystander shares common social identity with the victim the probability of intervention is enhanced, other things being equal. However, it is generally not possible to study such hypotheses experimentally for practical and ethical reasons. Here we show that an experiment that depicts a violent incident at life-size in immersive virtual reality lends support to the social identity explanation. 40 male supporters of Arsenal Football Club in England were recruited for a two-factor between-groups experiment: the victim was either an Arsenal supporter or not (in-group/out-group), and looked towards the participant for help or not during the confrontation. The response variables were the numbers of verbal and physical interventions by the participant during the violent argument. The number of physical interventions had a significantly greater mean in the in-group condition compared to the out-group. The more that participants perceived that the Victim was looking to them for help the greater the number of interventions in the in-group but not in the out-group. These results are supported by standard statistical analysis of variance, with more detailed findings obtained by a symbolic regression procedure based on genetic programming. Verbal interventions made during their experience, and analysis of post-experiment interview data suggest that in-group members were more prone to confrontational intervention compared to the out-group who were more prone to make statements to try to diffuse the situation. © 2013 Slater et al.

For most of the history of prejudice research, negativity has been treated as its emotional and cognitive signature, a conception that continues to dominate work on the topic. By this definition, prejudice occurs when we dislike or derogate members of other groups. Recent research, however, has highlighted the need for a more nuanced and ‘inclusive’ (Eagly 2004) perspective on the role of intergroup emotions and beliefs in sustaining discrimination. On the one hand, several independent lines of research have shown that unequal intergroup relations are often marked by attitudinal complexity, with positive responses such as affection and admiration mingling with negative responses such as contempt and resentment. Simple antipathy is the exception rather than the rule. On the other hand, there is mounting evidence that nurturing bonds of affection between the advantaged and the disadvantaged sometimes entrenches rather than disrupts wider patterns of discrimination. Notably, prejudice reduction interventions may have ironic effects on the political attitudes of the historically disadvantaged, decreasing their perceptions of injustice and willingness to engage in collective action to transform social inequalities. These developments raise a number of important questions. Has the time come to challenge the assumption that negative evaluations are inevitably the cognitive and affective hallmarks of discrimination?. Is the orthodox concept of prejudice in danger of side-tracking, if not obstructing, progress towards social justice in a fuller sense?. What are the prospects for reconciling a prejudice reduction model of change, designed to get people to like one another more, with a collective action model of change, designed to ignite struggles to achieve intergroup equality?

Although researchers know much about the causes of aggression, they know surprisingly little about how aggression leads to violence or how violence is controlled. To explore the microregulation of violence, we conducted a systematic behavioral analysis of footage from closed-circuit television surveillance of public spaces. Using 42 incidents involving 312 people, we compared aggressive incidents that ended in violence with those that did not. Behaviors of antagonists and third parties were coded as either escalating or conciliatory acts. Results showed that third parties were more likely to take conciliatory actions than to escalate violence and that this tendency increased as group size increased. This analysis revealed a pattern of third-party behaviors that prevent aggression from becoming violent and showed that conciliatory behaviors are more successful when carried out by multiple third parties than when carried out by one person. We conclude by emphasizing the importance of collective third-party dynamics in understanding conflict resolution.

Four experiments explored the interaction of group size, social categorization, and bystander behavior. In Study 1, increasing group size inhibited intervention in a street violence scenario when bystanders were strangers but encouraged intervention when bystanders were friends. Study 2 replicated and extended these findings to social category members. When gender identity was salient, group size encouraged intervention when bystanders and victim shared social category membership. In addition, group size interacted with context-specific norms that both inhibit and encourage helping. Study 3 used physical co-presence and gender identities to examine these social category effects. Increasing group size of women produced greater helping of a female victim, but increasing group size of men did not. Additionally, increasing numbers of out-group bystanders resulted in less intervention from women but more intervention from men. Study 4 replicated these findings with a measure of real-life helping behavior. Taken together, the findings indicate that the bystander effect is not a generic consequence of increasing group size. When bystanders share group-level psychological relationships, group size can encourage as well as inhibit helping.

Objectives: Belonging to groups can significantly affect people’s health and well-being for the better (‘the social cure’), or worse (‘the social curse’). Encouraging people to join groups is a central component of the Social Prescribing movement, however not everyone who might benefit from Social Prescribing aspires to participating in groups. This study aims to identify what barriers are preventing people from experiencing the associated health and wellbeing benefits of group belonging.
Method: Semi-structured interviews analysed using reflexive thematic analysis. Participants were 11 white British people (aged 48-86), 1 male and 10 female, recruited by a charity partner of a Social Prescribing project.
Results: the themes derived from the interviews are: 1) “The dread, the fear of being in a group”: When groups do not meet needs; 2) “I can remember as quite a young child backing out of things”: Accumulative barriers over the lifetime, and 3) “I’m singing away and feeling terribly miserable”: the challenges of fitting in with others in groups. The themes reflect how people can feel deterred from social interaction, which interferes with their ability to derive a sense of belonging or shared identity associated with the ‘social cure’.
Conclusions: a key challenge for Social Prescribing is to meet the social needs of people disinclined to join groups; groups can be detrimental to health and wellbeing if there are barriers to integration. Alternative ways of structuring groups or activities may be more effective and can still avail of the belonging and identity associated with ‘the social cure’.

Objective: Accumulating evidence shows that bystanders witnessing public disputes frequently intervene to help. However, little is known regarding the risks entailed for those bystanders who enter the fray to stop conflicts. This study systematically examined the prevalence of bystander victimizations and the associated risk factors. Method: Data were a cross-national sample of 93 surveillance camera recordings of real-life public disputes, capturing the potential victimizations of 417 intervening and 636 nonintervening bystanders. Results: Data showed that interveners were rarely physically harmed—at a rate of 3.6%—and noninterveners were virtually never victimized. Confirmatory regression results showed that conflict party affiliation was a moderately robust predictor of bystander victimization. The gender of the intervener was a highly fragile risk factor. More severe conflicts were not associated with a higher victimization likelihood. Conclusions: Our findings highlight the value of naturalistic observation for bystander research and emphasize the need for evidence-based bystander intervention recommendations.

Intergroup contact research has traditionally relied on retrospective accounts of intergroup encounters, mainly through survey-based or observational methods. This study introduces and tests the usability of a purpose-built, location-aware mobile application—the Contact Logger. This application enables the recording of interpersonal and intergroup encounters, in public and private spaces (both indoor and outdoor), in their here-and-now contexts. The main advantage of this approach, compared to traditional methods, lies in its ability to collect repeated and timely (near-time) self-assessments of individuals’ behaviours and experiences. It also allows for geographical location data to be logged. Usability testing was conducted in a real-world environment and took place over the course of seven days, during which participants (N = 12) logged every contact they encountered with an outgroup member (here: older people). Subsequently, participants completed a paper-and-pencil questionnaire, reporting on the usability and experience of using the Contact Logger. Results showed that the application is a viable and easy-to-use alternative to traditional methods. The information gathered aided the further development and optimisation of the application. The outcomes of this process are also briefly discussed.

Many violence prevention programs include a focus on the role of bystanders and third parties in violence prevention training. Central to this work has been the classic social psychological research on the “bystander effect”. However, recent research on bystander behavior shows that the bystander effect does not hold in violent or dangerous emergencies. Meta-analyses of the literature show that the presence of others can facilitate as well as inhibit intervention in emergencies. Studies of real-life bystander behavior captured on CCTV cameras shows that some bystander intervention is the norm and that the likelihood of bystanders being victimized is low. One reason for the limited effectiveness of violence reduction programs may be their approach to bystanders. We argue that violence reduction programs should: recognize that some intervention is likely (although it may not always be successful); see the group as a route to successful intervention rather than a threat to the likelihood of any single individual becoming an intervener; inform bystanders of the real risks of victimization; utilize the power of social relations between bystanders, victims, and perpetrators to enhance successful intervention; seek to deliver bystander intervention training in situ, rather than away from the context of the aggression or violence.

Narratives surrounding algorithmic surveillance typically emphasise negativity and concerns about privacy. In contrast, we argue that current research underestimates potentially positive consequences of algorithmic surveillance in the form of group-based recognition. Specifically, we test whether (accurate) algorithmic surveillance (i.e. the extent to which those surveilled believe surveillance mirrors their own self-concept) provides a vehicle for group-based recognition in two contexts: (1) those under outgroup surveillance and (2) surveillance from the perspective of stigmatised and misrecognised groups. In turn, we test whether this can lead to more positive (and less negative) feelings towards surveillance. Alongside this, we also test whether a countervailing negative pathway exists, whereby more accurate surveillance is associated with more privacy concern, and in turn, more negative (and less positive) feelings towards surveillance. The final study also tests whether positive perceptions of accurate surveillance arising through group-based recognition are limited only to misrecognised groups, or whether this is true for people more generally. Across seven studies, we test the core hypothesis that group-based recognition from accurate surveillance provides a basis for positive reactions to algorithmic surveillance that countervails the negative pathway through privacy concern. Overall, we found support for the positive pathway, whereby more accurate surveillance was associated with more positive feelings towards surveillance through group-based recognition. The positive pathway was present for both typically recognised and misrecognised groups. We also found partial support for the negative pathway; whereby privacy concern was associated with less positive feelings towards surveillance. However, we did not find that surveillance accuracy was associated with privacy concern; one implication of this is that the presence of surveillance per se overwhelms any additional effect of surveillance accuracy. Additionally, surveiller social identity (ingroup vs. outgroup) influenced both the positive and negative pathways: surveillance from an outgroup was considered less trustworthy than ingroup surveillance, which in turn predicted less positive outcomes in the form of more privacy concern and less group-based recognition. This thesis challenges the current techno-pessimistic view that algorithms are inherently negative and contributes to research that endeavours to gain a greater understanding of society’s relationship with algorithms and artificial intelligence.

Integrating security into software development involves more than learning principles or applying techniques. Security can be integrated into software development practice by following a middle path, through which developers draw together knowledge received through training and software development techniques.

the social identity approach suggests that group prototypical individuals have greater influence over fellow group members. This effect has been well-studied offline. Here, we use a novel method of assessing prototypicality in naturally occurring data to test whether this effect can be replicated in online communities. In Study 1a ( N = 53,049 Reddit users), we train a linguistic measure of prototypicality for two social groups: libertarians and entrepreneurs. We then validate this measure further to ensure it is not driven by demographics (Study 1b: N = 882) or local accommodation (Study 1c: N = 1,684 Silk Road users). In Study 2 ( N = 8,259), we correlate this measure of prototypicality with social network indicators of social influence. In line with the social identity approach, individuals who are more prototypical generate more responses from others. Implications for testing sociopsychological theories with naturally occurring data using computational approaches are discussed.

Violence prevention programs aim to raise awareness, change attitudes, normative beliefs, motivation, and behavioral responses. Many programs have been developed and evaluated, and optimistic claims about effectiveness made. Yet comprehensive guidance on program design, implementation, and evaluation is limited. The aim of this study was to provide an up-to-date review of evidence on what works for whom. A systematic search of PsycINFO, MEDLINE, ERIC, and Sociology Collection ProQuest identified 40 reviews and meta-analyses reporting on the effectiveness of violence prevention programs among young people (age 15–30) in educational institutions, published before October 2018. These included reviews of programs designed to reduce (i) bullying, (ii) dating and relationship violence, (iii) sexual assault, and (iv) antisocial behavior. Only evaluations that reported on behavioral outcomes such as perpetration, victimization, and bystander behavior were included. The reviewed evaluations reported on programs that were mainly implemented in high-income countries in Europe and North America. The majority found small effects on violence reduction and victimization and increases in self-reported bystander behavior. Our findings expose critical gaps in evaluation research in this area and provide recommendations on how to optimize the effectiveness of future programs.

© 2019 Elsevier Ltd Night-time economy (NTE) leisure zones, while providing local economic growth and positive social experiences, are hotspots for urban public violence. Research aimed at better understanding and thus reducing this violence has employed a range of empirical methods: official records, self-reports, experiments, and observational techniques. In this paper, we review the applications of these methodologies for analyzing NTE violence on key research dimensions, including mapping incidents across time and space; interpreting the motivations and meaning of violence; identifying social psychological background variables and health consequences; and the ability to examine mid-violent interactions. Further, we assess each method in terms of reliability, validity, and the potential for establishing causal claims. We demonstrate that there are fewer and less established methodologies available for examining the interactional dynamics of NTE violence. Using real-life NTE bystander intervention as a case example, we argue that video-based behavioral analysis is a promising method to address this gap. Given the infancy and relative lack of exposure of the video observational method, we provide recommendations for scholars interested in adopting this technique.

© 2019 American Psychological Association. Half a century of research on bystander behavior concludes that individuals are less likely to intervene during an emergency when in the presence of others than when alone. By contrast, little is known regarding the aggregated likelihood that at least someone present at an emergency will do something to help. The importance of establishing this aggregated intervention baseline is not only of scholarly interest but is also the most pressing question for actual public victims-will I receive help if needed? the current article describes the largest systematic study of real-life bystander intervention in actual public conflicts captured by surveillance cameras. Using a unique cross-national video dataset from the United Kingdom, the Netherlands, and South Africa (N = 219), we show that in 9 of 10 public conflicts, at least 1 bystander, but typically several, will do something to help. We record similar likelihoods of intervention across the 3 national contexts, which differ greatly in levels of perceived public safety. Finally, we find that increased bystander presence is related to a greater likelihood that someone will intervene. Taken together these findings allay the widespread fear that bystanders rarely intervene to help. We argue that it is time for psychology to change the narrative away from an absence of help and toward a new understanding of what makes intervention successful or unsuccessful.

Post-aggression consolation is assumed to occur in humans as well as in chimpanzees. While consolation following peer aggression has been observed in children, systematic evidence of consolation in human adults is rare. We used surveillance camera footage of the immediate aftermath of nonfatal robberies to observe the behaviors and characteristics of victims and bystanders. Consistent with empathy explanations, we found that consolation was linked to social closeness rather than physical closeness. While females were more likely to console than males, males and females were equally likely to be consoled. Furthermore, we show that high levels of threat during the robbery increased the likelihood of receiving consolation afterwards. These patterns resemble post-aggression consolation in chimpanzees and suggest that emotions of empathic concern are involved in consolation across humans and chimpanzees.

Low cost digital cameras in smartphones and wearable devices make it easy for people to automatically capture and share images as a visual lifelog. Having been inspired by a US campus based study that explored individual privacy behaviours of visual lifeloggers, we conducted a similar study on a UK campus, however we also focussed on the privacy behaviours of groups of lifeloggers. We argue for the importance of replicability and therefore we built a publicly available toolkit, which includes camera design, study guidelines and source code. Our results show some similar sharing behaviour to the US based study: people tried to preserve the privacy of strangers, but we found fewer bystander reactions despite using a more obvious camera. In contrast, we did not find a reluctance to share images of screens but we did find that images of vices were shared less. Regarding privacy behaviours in groups of lifeloggers, we found that people were more willing to share images of people they were interacting with than of strangers, that lifelogging in groups could change what defines a private space, and that lifelogging groups establish different rules to manage privacy for those inside and outside the group.

Using insights from a review of recent research on social identity approaches to helping, the Chapter sets out four key elements of a social identity approach to helping in emergencies: the salience of social identity, the boundaries of social identity, the contents of social identity, and the strategic interests of social identity. Evidence that illustrates the impact of social identity processes on group size and helping, which has traditionally focused on the inhibition of helping in the presence of others, is then reviewed. Finally, recent developments in the literature on intergroup emotions are considered, and their impact on a social identity approach to helping in emergencies is explored, highlighting the relatively neglected social identity relationship between bystanders and perpetrators. The review concludes by considering the current state of knowledge of a social identity approach to helping in emergencies, and identifies important questions that remain to be addressed. © 2014 © 2014 European Association of Social Psychology.

The attempt to regenerate city centres has led to the creation of a 'night-time economy' (NTE) based around alcohol-led entertainment. This has been accompanied by an increase of violence. Using insights from social identity research on collective action, we argue that NTE violence can be viewed as a group-level phenomenon. Twenty focus groups were conducted with participants who socialise together (total number of participants=53). Participants discussed their experiences of the NTE, including violence. A thematic analysis of the transcripts drew out four ways in which NTE violence is discussed in group terms: intergroup violence, intragroup violence, intragroup intervention (escalation) and intragroup intervention (regulation). The analysis reveals that groups can have both negative and positive roles in NTE violence, including regulating fellow group members away from violence. In demonstrating the importance of intragroup regulation of violence in the NTE, we extend social identity research beyond the focus on intergroup crowd violence and reveal the practical potential of harnessing such processes in anti-violence interventions. © 2012 John Wiley & Sons, Ltd.

This response clarifies, qualifies, and develops our critique of the limits of intergroup liking as a means of challenging intergroup inequality. It does not dispute that dominant groups may espouse negative attitudes towards subordinate groups. Nor does it dispute that prejudice reduction can be an effective way of tackling resulting forms of intergroup hostility. What it does dispute is the assumption that getting dominant group members and subordinate group members to like each other more is the best way of improving intergroup relations that are characterized by relatively stable, institutionally embedded, relations of inequality. In other words, the main target of our critique is the model of change that underlies prejudice reduction interventions and the mainstream concept of prejudice on which they are based. © 2012 Cambridge University Press.

This article explores accounts of bystanders to female-on-female public violence. Group interviews with participants in the night-time economy are carried out. Whereas men tend to respond to the discussion topic of female-on-female violence with laughter, this laughter reveals ambivalence and discomfort as much as amusement. Men seem to negotiate the tension between the expectation that they should intervene in emergencies and a catalogue of costs that attend intervention. Female bystanders appear to have a different set of concerns. They talk about feelings of shame at the interpersonal and the group level. Women cite the public spectacle, and the opportunity for men to demean or sexualize women, as reasons for intervention. The article concludes with some recommendations about the importance of exploring female violence in its own terms, beginning with a series of identified moral and social dilemmas incurred within possible third-party intervention. © the Author(s) 2012.

In this paper, we explore how white Catholic men talk about the indirect dilemma of non-intervention for black ethnic outgroups. We illustrate how they mobilise global categorisation (all humanity) and use various forms of denial to deal with their non-involvement. Having analyzed representative fragments of their prejudice avoidance talk, we conclude with some observation about the strategic deployment of categories and denial forms as part of identity management talk. In contrast to quantitative research that oversimplifies the ingroup-outgroup distinction, we show how the status and outgroupness levels of the needy appear to be both flexible and intricate, which depends on the often-ignored intersecting cultural factors, like the respondents' and victims' ethnic, racial and religious identities. © 2012: Marek Palasinski, Mark Levine, Jackie Abell, and Nova Southeastern University.

The attempt to regenerate city centres has led to the creation of a ‘night-time economy’ (NTE) based around alcohol-led entertainment.
This has been accompanied by an increase of violence. Using insights from social identity research on collective action, we
argue that NTE violence can be viewed as a group-level phenomenon. Twenty focus groups were conducted with participants
who socialise together (total number of participants=53). Participants discussed their experiences of the NTE, including violence.
A thematic analysis of the transcripts drew out four ways in which NTE violence is discussed in group terms: intergroup violence,
intragroup violence, intragroup intervention (escalation) and intragroup intervention (regulation). The analysis reveals that groups
can have both negative and positive roles in NTE violence, including regulating fellow group members away from violence. In
demonstrating the importance of intragroup regulation of violence in the NTE, we extend social identity research beyond the focus
on intergroup crowd violence and reveal the practical potential of harnessing such processes in anti-violence interventions.

Three studies consider the implicit bystander effect in the light of recent advances in social identity approaches to helping. Drawing on the social identity model of deindividuation effects we argue that the implicit bystander effect is shaped not by the number of others imagined, but by who those others are imagined to be. Studies 1 and 2 demonstrate that, when group membership is primed, increasing group size can facilitate helping in line with the norms and values of the group. Study 3 explores mediation processes in group level helping. As group size increases, female participants react faster to words associated with communalism when others are imagined as women rather than strangers. The paper demonstrates that group size and helping behaviour is qualified by an implicit identity effect.

Four experiments explored the interaction of group size, social categorization, and bystander behavior. In Study 1, increasing group size inhibited intervention in a street violence scenario when bystanders were strangers but encouraged intervention when bystanders were friends. Study 2 replicated and extended these findings to social category members. When gender identity was salient, group size encouraged intervention when bystanders and victim shared social category membership. In addition, group size interacted with context-specific norms that both inhibit and encourage helping. Study 3 used physical co-presence and gender identities to examine these social category effects. Increasing group size of women produced greater helping of a female victim, but increasing group size of men did not. Additionally, increasing numbers of out-group bystanders resulted in less intervention from women but more intervention from men. Study 4 replicated these findings with a measure of real-life helping behavior. Taken together, the findings indicate that the bystander effect is not a generic consequence of increasing group size. When bystanders share group-level psychological relationships, group size can encourage as well as inhibit helping.

Three studies consider a basis for intergroup helping. Specifically, they show that group members may help others to disconfirm a stereotype of their own group as mean. Study 1 shows that Scots believe they are seen as mean by the English, resent this stereotype, are motivated to refute it, and believe out-group helping is a particularly effective way of doing so. Study 2 shows that increasing the salience of the English stereotype of the Scottish as mean leads Scots to accentuate the extent to which Scots are depicted as generous. Study 3 shows that increasing the salience of the stereotype of the Scots as mean results in an increase in the help volunteered to out-group members. These results highlight how strategic concerns may result in out-group helping. In turn, they underscore the point that helping others may be a means to advance a group's interest. © 2007 by the Society for Personality and Social Psychology, Inc.

This article argues that an iconic event in the history of helping research-the story of the 38 witnesses who remained inactive during the murder of Kitty Genovese-is not supported by the available evidence. Using archive material, the authors show that there is no evidence for the presence of 38 witnesses, or that witnesses observed the murder, or that witnesses remained inactive. Drawing a distinction between the robust bystander research tradition and the story of the 38 witnesses, the authors explore the consequences of the story for the discipline of psychology. They argue that the story itself plays a key role in psychology textbooks. They also suggest that the story marks a new way of conceptualizing the dangers of immersion in social groups. Finally, they suggest that the story itself has become a modern parable, the telling of which has served to limit the scope of inquiry into emergency helping. © 2007 American Psychological Association.

Drawing on research in urban sociology, cultural geography, and social psychology, this paper explores some of the moral rules that govern social relations in public places. In particular, we consider how certain practices become classified as everyday incivilities -infractions of the moral order that sustains public life. In order to develop this notion, we draw illustrations from an ongoing research project that is investigating social attitudes towards "street drinking," an activity that has led to the creation of "alcohol-free zones" in over 100 British cities during the past decade. As an emergent theme, this research has suggested that the classification of street drinking as either acceptable or unacceptable conduct is contingent upon the social construction of public space that users invoke. This theme is discussed in the context of wider struggles over citizenship and social control in the public domain-struggles manifest within "ideological dilemmas" (Billig et al. 1988) over the limits of free conduct, the tension between open and closed public spaces, and the attempt to distinguish "admissible" from "inadmissible" publics. © 2006 International Society of Political Psychology.

This paper investigates the arguments used in public documents to mobilise Bulgarians against the deportation of Jews in World War II. We focus on the key documents relating to the first wave of mobilisation in 1940-1941 as provided by Todorov in the Fragility of Goodness (2001). We demonstrate that these documents are based on three types of argument. The first, category inclusion, treats the Jews as part of a common ingroup rather than as constituting a separate outgroup. The second, category norms, proposes that help for those under attack is a core aspect of ingroup identity. The third, category interest, suggests that the ingroup will be harmed if Jews are persecuted. In each case, the predominant category on which arguments are based is national identity (i.e. 'we Bulgarians. '). This analysis is used to validate and extend a social identity of model of helping. The theoretical and practical implications of such an approach are considered in the discussion. Copyright © 2006 John Wiley & Sons, Ltd.

The authors draw upon the principles of the social identity tradition in order to elaborate a psychological model of mass communication. This centres on the way in which people construe their social identities and the meanings of events for these identities. They then go on to look at the ways in which these principles have been employed both to mobilize collective support for genocide and collective resistance to genocide. They conclude that it is critical to understand these principles and to apply them effectively in order to promote social harmony and the defence of vulnerable groups. © 2005, International Committee of the Red Cross.

Two experiments exploring the effects of social category membership on real-life helping behavior are reported. In Study 1, intergroup rivalries between soccer fans are used to examine the role of identity in emergency helping. An injured stranger wearing an in-group team shirt is more likely to be helped than when wearing a rival team shirt or an unbranded sports shirt. In Study 2, a more inclusive social categorization is made salient for potential helpers. Helping is extended to those who were previously identified as out-group members but not to those who do not display signs of group membership. Taken together, the studies show the importance of both shared identity between bystander and victim and the inclusiveness of salient identity for increasing the likelihood of emergency intervention.

The authors developed a Self-Categorization Theory (SCT) approach to bystander behavior. Participants were 100 undergraduates at an English university. The authors made either a European or a British identity salient. Participants then rated their likelihood of offering both financial and political help after natural disasters in Europe and South America. When European (but not British) identity was salient, participants were less likely to offer help for disasters in South America than Europe. They were also more likely to offer financial help after disasters in Europe when European non-British identity was salient. There were no differences in levels of emotional response to disasters by identity salience. Results indicate that social category relations rather than geographical proximity or emotional reaction are most important in increasing helping behavior after natural disasters.

This paper begins by problematizing the ‘taken for granted’ status of Newtonian linear time at the heart of (social) psychology. Borrowing from Adam, the paper makes a distinction between an ‘events in time’ and ‘time in events’ approach to social psychology. It argues that a ‘time in events’ approach helps to reveal the importance of multiple times for social psychological theories and practices. To demonstrate this approach, it considers some of the multiple times that are relevant for analysing the concept of ‘identity’. It also explores the multiple times of the research encounter. In doing so, it suggests that traditional dichotomies in social psychology between synchronic and diachronic methods, and between experimental and qualitative methods, can be dissolved by this focus on the temporal.

This paper outlines a new approach to the study of bystander intervention. Using insights derived from self-categorization theory (Turner, Hogg, Oakes, Reicher, & Wetherell, 1987), we explore the social category relations among those present in the context of physical violence. The paper describes two experiments that manipulate the social category relations between (a) bystander and fellow bystanders, and (b) bystander and victim. Analysis indicates that fellow bystanders are only influential when they are in-group rather than out-group members. Furthermore, bystanders are more likely to help victims who are described as in-group as opposed to out-group members. Overall, the findings suggest an important role for a self-categorization perspective in developing strategies to promote bystander intervention.

Objectives. This paper describes two experiments which develop a self-categorization theory (SCT) approach to the way people make sense of their symptoms. The first experiment builds upon a study by Levine and Reicher in which it is proposed that symptoms are evaluated, not against pre-existing illness representations, but by reference to their impact on situationally salient identities. The second experiment extends the SCT perspective on symptom evaluation to argue that the identities that are instrumental in assigning meaning to symptoms are themselves situationally constructed. Design and methods. In the first experiment, 40 female secretaries, defined either in terms of a 'secretary' identity or in terms of a 'gender' identity, were asked to evaluate a number of scenarios which describe different illnesses or injuries. In the second experiment 40 men from a rugby club were asked to evaluate a number of scenarios relating to illness and injuries. The identity from which scenarios were evaluated was held constant, but the comparison groups (or frame of reference) was manipulated. Results. Overall, the results of the first study provide clear evidence that the significance ascribed to scenarios depends on which identity is salient. The results from the second study provided clear evidence that the significance ascribed by the males to the scenarios was a functions of the comparison groups they believed they were being compared to. Conclusions. Taken together, these two experiments provide strong evidence for the viability of an SCT approach to symptom evaluation.

Bystander apathy is a long established phenomenon in social psychology which has yet to be translated into practical strategies for increasing bystander intervention. This paper argues that the traditional paradigm is hampered by a focus on the physical co-presence of others rather than an analysis of the social meanings inherent in (non)intervention. The testimony provided by 38 bystanders at the trial of two 10-year-old boys for the murder of 2-and-a-half-year-old James Bulger is analyzed. It is argued that their failure to intervene can be attributed to the fact that they assumed - or were told - that the three boys were brothers. The way in which this category of "the family" served to prohibit or deflect intervention is analyzed. This approach is contrasted with a traditional bystander apathy account of the bystanders' actions in the Bulger case. It is argued that bystander (non)intervention phenomenon should be analyzed in terms of the construction of social categories in local contexts.

A central theme in both medical sociology and health psychology is how people make sense of their symptoms. Both literatures, despite their stress on different aspects of the health evaluation process, see illness in terms of matching present symptoms to an underlying understanding of illness. In this paper we argue that such accounts have difficulty in explaining the impact of contextual factors on how symptoms are evaluated. We therefore propose a model based on self-categorization theory (Turner, Hogg, Oakes, Reicher & Wetherell, 1987). It is proposed that symptoms are evaluated, not against pre-existing illness representations, but by reference to their impact on situationally salient identities. In support of this an experiment is described which involves students who are training to be physical education (PE) teachers. They are defined either in terms of a 'PE student' identity or in terms of a 'gender' identity and asked to evaluate a number of scenarios which describe different illnesses and injuries. Overall, the results provide clear evidence that the significance ascribed to scenarios depends on which identity is salient and hence indicate the viability of a self-categorization theory approach to symptom evaluation.

What happens if one treats social identity as a flexible resource in conversational interaction? Close attention to the sequencing of talk suggests that speakers' identities are much more subtle than simple pre-given category labels suggest, and that they change rapidly as a function of the ephemeral (but socially consequential) demands ot the situation. Were a psychologist to have sampled the interaction only at one given point, they would have seen a participant using, or being attributed with, only one identity; but we show that speakers use, and attribute each other with, a variety of different identities as their business progresses. In so doing, the speakers can be seen not only to avow contradictory identities but also to invoke both group distinctiveness and similarity - and neither of these strategies are easy to square with social psychological theories of identity. We put what we find in this particular case study into the debate between, on the one hand, ethnomethodological preference for working from participants' own orientations to identity and, on the other hand, social psychological research practices which tend to privilege analytically given social categories. At the very least, we argue, the social psychological approach can be enriched by attending more to identity as a matter of situated description and less as a matter of perceptuo-cognitive processing.
