Beyond 'stampedes': Towards a new psychology of crowd crush disasters.

The Bethnal Green tube shelter disaster, in which 173 people died, is a significant event in both history and psychology. While notions of 'panic' and 'stampede' have been discredited in contemporary psychology and disaster research as explanations for crowd crushes, Bethnal Green has been put forward as the exception that proves the rule. Alternative explanations for crushing disasters focus on mismanagement and physical factors, and lack a psychology. We analysed 85 witness statements from the Bethnal Green tragedy to develop a new psychological account of crowd disasters. Contrary to the established view of the Bethnal Green disaster as caused by widespread public overreaction to the sound of rockets, our analysis suggests that public perceptions were contextually calibrated to a situation of genuine threat; that only a small minority misperceived the sound; and that therefore, this cannot account for the surge behaviour in the majority. We develop a new model, in which crowd flight behaviour in response to threat is normatively structured rather than uncontrolled, and in which crowd density combines with both limited information on obstruction and normatively expected ingress behaviour to create a crushing disaster.

Social identification and risk dynamics: How perceptions of (inter)personal and collective risk impact the adoption of COVID-19 preventative behaviors.

Public adoption of preventative behaviors to reduce the transmission of COVID-19 is crucial to managing the pandemic, and so it is vital to determine what factors influence the uptake of those behaviors. Previous studies have identified COVID-19 risk perceptions as a key factor, but this work has typically been limited both in assuming that risk means risk to the personal self, and in being reliant on self-reported data. Drawing on the social identity approach, we conducted two online studies in which we investigated the effects of two different types of risk on preventative measure taking: risk to the personal self and risk to the collective self (i.e., members of a group with which one identifies). Both studies involved behavioral measures using innovative interactive tasks. In Study 1 (n = 199; data collected 27 May 2021), we investigated the effects of (inter)personal and collective risk on physical distancing. In Study 2 (n = 553; data collected 20 September 2021), we investigated the effects of (inter)personal and collective risk on the speed at which tests are booked as COVID-19 symptoms develop. In both studies, we find that perceptions of collective risk, but not perceptions of (inter)personal risk, influence the extent to which preventative measures are adopted. We discuss the implications both conceptually (as they relate to both the conceptualization of risk and social identity processes) and also practically (in terms of the implications for public health communications).

A warrant for violence? An analysis of Donald Trump's speech before the US Capitol attack.

On January 6th, 2021, Donald Trump's speech during a 'Save America' rally was followed by mass violence, with Trump's supporters storming the U.S. Capitol to prevent the certification of Joe Biden's victory in the presidential election. In its wake, there was a great deal of debate around whether the speech contained direct instructions for the subsequent violence. In this paper, we use a social identity perspective on leadership (and more specifically, on toxic leadership) to analyse the speech and see how its overall argument relates to violence. We show that Trump's argument rests on the populist distinction between the American people and elites. He moralises these groups as good and evil respectively and proposes that the very existence of America is under threat if the election result stands. On this basis he proposes that all true Americans are obligated to act in order prevent Biden's certification and to ensure that the good prevails over evil. While Trump does not explicitly say what such action entails, he also removes normative and moral impediments to extreme action. In this way, taken as a whole, Trump's speech enables rather than demands violence and ultimately it provides a warrant for the violence that ensued.

Engaged followership and toxic science: Exploring the effect of prototypicality on willingness to follow harmful experimental instructions.

Drawing on the 'engaged followership' reinterpretation of Milgram's work on obedience, four studies (three pre-registered) examine the extent to which people's willingness to follow an experimenter's instructions is dependent on the perceived prototypicality of the science they are supposedly advancing. In Studies 1, 2 and 3, participants took part in a study that was described as advancing either 'hard' (prototypical) science (i.e., neuroscience) or 'soft' (non-prototypical) science (i.e., social science) before completing an online analogue of Milgram's 'Obedience to Authority' paradigm. In Studies 1 and 2, participants in the neuroscience condition completed more trials than those in the social science condition. This effect was not replicated in Study 3, possibly because the timing of data collection (late 2020) coincided with an emphasis on social science's importance in controlling COVID-19. Results of a final cross-sectional study (Study 4) indicated that participants who perceived the study to be more prototypical of science found it more worthwhile, reported making a wider contribution by taking part, reported less dislike for the task, more happiness at having taken part, and more trust in the researchers, all of which indirectly predicted greater followership. Implications for the theoretical understanding of obedience to toxic instructions are discussed.

Is it really "panic buying"? Public perceptions and experiences of extra buying at the onset of the COVID-19 pandemic.

Shopping behaviour in response to extreme events is often characterized as "panic buying" which connotes irrationality and loss of control. However, "panic buying" has been criticized for attributing shopping behaviour to people's alleged psychological frailty while ignoring other psychological and structural factors that might be at play. We report a qualitative exploration of the experiences and understandings of shopping behaviour of members of the public at the onset of the COVID-19 pandemic. Through a thematic analysis of semi-structured interviews with 23 participants, we developed three themes. The first theme addresses people's understandings of "panic buying". When participants referred to "panic buying" they meant observed product shortages (rather than the underlying psychological processes that can lead to such behaviours), preparedness behaviours, or emotions such as fear and worry. The second theme focuses on the influence of the media and other people's behaviour in shaping subsequent shopping behaviours. The third theme addresses the meaningful motivations behind increased shopping, which participants described in terms of preparedness; some participants reported increased shopping behaviours as a response to other people stockpiling, to reduce their trips to supermarkets, or to prepare for product shortages and longer stays at home. Overall, despite frequently using the term 'panic', the irrationalist connotations of "panic buying" were largely absent from participants' accounts. Thus, "panic buying" is not a useful concept and should not be used as it constructs expected responses to threat as irrational or pathological. It can also facilitate such behaviours, creating a self-fulfilling prophecy.

Social norms, social identities and the COVID-19 pandemic: Theory and recommendations.

Sustained mass behaviour change is needed to tackle the COVID-19 pandemic, but many of the required changes run contrary to existing social norms (e.g., physical closeness with in-group members). This paper explains how social norms and social identities are critical to explaining and changing public behaviour. Recommendations are presented for how to harness these social processes to maximise adherence to COVID-19 public health guidance. Specifically, we recommend that public health messages clearly define who the target group is, are framed as identity-affirming rather than identity-contradictory, include complementary injunctive and descriptive social norm information, are delivered by in-group members and that support is provided to enable the public to perform the requested behaviours.

Self-categorization as a basis of behavioural mimicry: Experiments in The Hive.

INTRODUCTION: Do we always do what others do, and, if not, when and under what conditions do we do so? In this paper we test the hypothesis that mimicry is moderated by the mere knowledge of whether the source is a member of the same social category as ourselves. METHODS: We investigated group influence on mimicry using three tasks on a software platform which interfaces with mobile computing devices to allow the controlled study of collective behaviour in an everyday environment. RESULTS: Overall, participants (N = 965) were influenced by the movements of confederates (represented as dots on a screen) who belonged to their own category in both purposive and incidental tasks. CONCLUSION: Our results are compatible with collective level explanations of social influence premised on shared social identification. This includes both a heuristic of unintended mimicry (the acts of group members are diagnostic of how one should act), and communication of affiliation (based on a desire to make one's group cohesive). The results are incompatible with traditional 'contagion' accounts which suggest mimicry is automatic and inevitable. The results have practical implications for designing behavioural interventions which can harness the power of copying behaviour, for example in emergency evacuations.

Trends in the perceived body size of adolescent males and females in Scotland, 1990-2014: changing associations with mental well-being.

OBJECTIVES: This paper explores trends in Scottish adolescents' body size perceptions and associated mental well-being outcomes. METHODS: Data were collected on Scottish 11-, 13-, and 15-year-olds by the Health Behaviour in School-aged Children study between 1990 and 2014 (n = 42,312). Logistic regression was used to examine changes in the prevalence of over- and underweight perceptions. Ordinal and linear regressions were used to examine changes in the association between body perception and mental well-being. RESULTS: Little change was observed in over- or underweight perceptions. However, relative to those perceiving their body as 'about right', those perceiving themselves as overweight reported decreasing confidence (all groups), decreasing happiness (11- and 13-year-old girls), and increasing psychological health symptoms (all girls and 15-year-old boys). Perceived underweight is associated with poor well-being, especially in males, but we present little evidence that this is a recent phenomenon. CONCLUSIONS: We present evidence suggesting that the association between body size perception and poor mental health in adolescence is changing over time. This may play a role in the recently observed worsening of mental well-being in Scottish adolescents.

Trends in the sexual behaviour of 15-year olds in Scotland: 2002-14.

Background: Early sexual initiation and inadequate contraceptive use can place adolescents at increased risk of unplanned pregnancy and sexually transmitted infections. These behaviours are patterned by gender and may be linked to social inequalities. This paper examines trends in sexual initiation and contraceptive use by gender and family affluence for Scottish adolescents. Methods: Cross-sectional data from four nationally representative survey cycles (2002, 2004, 2010, 2014) (n = 8895) (mean age = 15.57) were analysed. Logistic regressions examined the impact of survey year on sexual initiation, condom use and birth control pill (BCP) use at last sex; as well as any changes over time in association between family affluence and the three sexual behaviours. Analyses were stratified by gender. Results: Between 2002 and 2014, adolescent males and females became less likely to report having had sex. Low family affluence females were more likely to have had sex than high family affluence females, and this relationship did not change over time. Condom use at last sex was reported less by males since 2002, and by females since 2006. Low family affluence males and females were less likely to use condoms than high family affluence participants, and these relationships did not change over time. There were no effects of time or family affluence for BCP use. Conclusion: There has been a reduction in the proportion of 15-year olds in Scotland who have ever had sex, but also a decrease in condom use for this group. Economic inequalities persist for sexual initiation and condom use.

Trends in bullying victimization in Scottish adolescents 1994-2014: changing associations with mental well-being.

OBJECTIVES: Bullying victimization among schoolchildren is a major public health concern. This paper aims to analyse the changing associations over two decades between bullying victimization and mental well-being in a representative Scottish schoolchildren sample. METHODS: Data were collected in six rounds of the cross-sectional Health Behaviour in School-aged Children study in Scotland, with 42,312 adolescents (aged 11, 13 and 15 years). Logistic and linear regressions were used to examine changes in the association between bullying victimization and mental well-being. RESULTS: The prevalence of bullying victimization rates in Scotland increased between 1994 and 2014 for most age-gender groups, apart from 13-year-old boys and 15-year-old girls. Over time, female victims reported less confidence and happiness and more psychological complaints than their non-bullied counterparts. This worsening effect over time was not observed in boys. CONCLUSIONS: Overall, our evidence indicates that the associations between bullying victimization and poor mental well-being strengthened overtime for bullied girls. This finding might partly explain the observed deterioration in mental health indicators among Scottish adolescent girls.

Trends in Adolescent Overweight Perception and Its Association With Psychosomatic Health 2002-2014: Evidence From 33 Countries.

PURPOSE: Perceiving oneself as overweight is common and strongly associated with adolescents' subjective well-being. The prevalence of overweight perceptions and their impact on well-being may have increased over the past decade due to an increase in the salience of weight-related issues. This study examines trends (2002-2014) in the prevalence of adolescent overweight perceptions and their association with psychosomatic complaints. METHODS: Data from 15-year-old adolescents were obtained between 2002 and 2014 in four rounds of the Health Behaviour in School-aged Children study in 33 countries in Europe and North America (N = 187,511). Design-adjusted logistic regressions were used to quantify changes in overweight perceptions over time. Linear modeling was used to assess change in the association between perceived overweight and self-reported psychosomatic complaint burden, adjusting for overweight status. RESULTS: Among boys, 10 of 33 countries saw an increase in overweight perceptions between 2002 and 2014, with Russia, Estonia, and Latvia showing the most pronounced year-on-year increases. Only England, France, Germany, and Norway saw an increase in the positive association between overweight perceptions and psychosomatic complaints among boys. Among girls, most countries (28/33) saw no change in the prevalence of overweight perceptions, with the prevalence over 40% in most nations. However, in 12 countries, the association between overweight perceptions and psychosomatic complaints increased among girls, with particularly strong changes seen in Scotland and Norway. CONCLUSIONS: Evidence is presented which suggests that for adolescent girls in 12 Northern and Western European countries and for boys in four perceiving oneself as overweight may be increasingly deleterious for psychosomatic health.

Preliminary research informing policy on remote alcohol monitoring in criminal justice: the Scottish experience.

OBJECTIVES: To explore the views of Scottish offenders on the impact of alcohol on their experience of offending and their lives in general. Furthermore, to explore their views on the concept of remote alcohol monitoring (RAM) as a way to address alcohol misuse upon liberation from prison. METHODS: A convenience sample of 12 serving offenders participated in one of three focus groups. Data were analysed using the principles of thematic analysis. RESULTS: Analysis of the data revealed the significant impact of alcohol on the lives of the participants. Key themes included the amount and frequency of alcohol consumption; the association of alcohol with harm; the association of alcohol with offending; the previous attempts to reduce alcohol consumption and possible reasons for failure; and the views of participants on the utility of RAM in relation to crime prevention. CONCLUSIONS: Participants had significant issues with alcohol misuse prior to incarceration that had impacted on their offending and resulted in both health and social harms. Participants were generally positive but pragmatic about RAM, recognising that technology alone may not be enough to change deeply ingrained and addictive behaviours.

Core disgust is attenuated by ingroup relations.

We present the first experimental evidence to our knowledge that ingroup relations attenuate core disgust and that this helps explain the ability of groups to coact. In study 1, 45 student participants smelled a sweaty t-shirt bearing the logo of another university, with either their student identity (ingroup condition), their specific university identity (outgroup condition), or their personal identity (interpersonal condition) made salient. Self-reported disgust was lower in the ingroup condition than in the other conditions, and disgust mediated the relationship between condition and willingness to interact with target. In study 2, 90 student participants smelled a sweaty target t-shirt bearing either the logo of their own university, another university, or no logo, with either their student identity or their specific university identity made salient. Walking time to wash hands and pumps of soap indicated that disgust was lower where the relationship between participant and target was ingroup rather than outgroup or ambivalent (no logo).

Unemployment, Parental Distress and Youth Emotional Well-Being: The Moderation Roles of Parent-Youth Relationship and Financial Deprivation.

We investigated, in a sample of 112 unemployed parents of adolescents aged 10-19 years, the links between parental distress and change in youth emotional problems related to parental unemployment, and the moderation roles of parent-youth relationship and financial deprivation. Data were analyzed using descriptive statistics and correlations. Further, simple moderation, additive moderation, and moderated moderation models of regression were performed to analyze the effects of parental distress, parent-youth relationship and financial deprivation in predicting change in youth emotional problems related to parental unemployment. Results show that parental distress moderated by parent-youth relationship predicted levels of change in youth emotional problems related to parental unemployment. This study provides evidence that during job loss, parental distress is linked to youth emotional well-being and that parent-youth relationships play an important moderation role. This raises the importance of further researching parental distress impacts on youth well-being, especially during periods of high unemployment rates.

An experimental trial exploring the impact of continuous transdermal alcohol monitoring upon alcohol consumption in a cohort of male students.

OBJECTIVE: To examine the impact of continuous transdermal alcohol monitoring upon alcohol consumption in male students at a Scottish university. METHOD: Using a within-subject mixed-methods design, 60 male university students were randomly allocated into three experimental conditions using AUDIT score stratified sampling. Participants in Conditions A and B were asked not to consume alcohol for a 14-day period, with those in Condition A additionally being required to wear a continuous transdermal alcohol monitoring anklet. Condition C participants wore an anklet and were asked to continue consuming alcohol as normal. Alcohol consumption was measured through alcohol timeline follow-back, and using data collected from the anklets where available. Diaries and focus groups explored participants' experiences of the trial. RESULTS: Alcohol consumption during the 14-day trial decreased significantly for participants in Conditions A and B, but not in C. There was no significant relative difference in units of alcohol consumed between Conditions A and B, but significantly fewer participants in Condition A drank alcohol than in Condition B. Possible reasons for this difference identified from the focus groups and diaries included the anklet acting as a reminder of commitment to the study (and the agreement to sobriety), participants feeling under surveillance, and the use of the anklet as a tool to resist social pressure to consume alcohol. CONCLUSIONS: The study provided experience in using continuous transdermal alcohol monitors in an experimental context, and demonstrated ways in which the technology may be supportive in facilitating sobriety. Results from the study have been used to design a research project using continuous transdermal alcohol monitors with ex-offenders who recognise a link between their alcohol consumption and offending behaviour.

Anxiety about anxiety in medical undergraduates.

BACKGROUND: Effective communication with patients is a vital ability for a doctor, and therefore training in communication skills forms an important component of the undergraduate medical curriculum. However, some medical undergraduates experience anxiety in communicating with patients and this makes it difficult for them to communicate with patients effectively. We developed workshops to equip students with skills to reduce communication-related anxiety, but turnout was low and only female students participated. PURPOSES: This study investigated the barriers that existed to workshop participation in order to inform the development of future workshops. METHODS: Semi-structured interviews with medical students who were completing their pre-clinical training (n = 16) were carried out. Interviews were transcribed and thematically analysed. RESULTS: Participants recognised symptoms of anxiety, and some reported experiencing it when speaking with patients. Participants acknowledged that the workshops would be useful to some students. Labelling the workshops as dealing with 'anxiety' contributed to non-participation, as students perceived their attendance as potentially showing weakness to fellow students and to medical school staff. Our findings indicated that the stigma attached to seeking guidance for communication-related anxiety is exacerbated for male students and by the competitive medical school environment. CONCLUSIONS: Attitudes towards 'anxiety' and experiencing anxiety can act as a barrier towards seeking support for communication-related anxiety.
