On the Actual Risk of Bystander Intervention: A Statistical Study Based on Naturally Occurring Violent Emergencies

Objectives: Bystander studies have rarely considered the victimization risk associated with intervention into violent, dangerous emergencies. To address this gap, we aim to identify factors that influence bystanders’ risk of being physically victimized. Method: We observed bystander behavior from video surveillance footage of naturally occurring violence in nighttime economy settings, and data were analyzed with a logistic regression model. Results: Data show that approximately one of the six interventions results in some type of victimization, typically with a relatively low degree of severity. The bystander’s social group membership, the setting of the emergency, and the bystander’s intervention type are estimated as risk factors for victimization. Conclusions: Previous research suggests that a bystander’s social group membership with victims promotes intervention behavior. Our results expand the role of social group membership as being a factor that also influences whether the intervening bystander is victimized.

Consolation in the aftermath of robberies resembles post-aggression consolation in chimpanzees

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.

Stress Response and Cognitive Performance Modulation in Classroom versus Natural Environments: A Quasi-Experimental Pilot Study with Children

Stress during childhood can have mental and somatic health influences that track throughout life. Previous research attributes stress-reducing effects to natural environments, but has mainly focused on adults and often following leisurely relaxation in natural environments. This pilot study explores the impact of natural environments on stress response during rest and mental load and cognitive performance in 47 children aged 10–12 years in a school context. Heart rate variability measures indexing tonic, event, and phasic vagal tone and attention scores were compared across classroom and natural environments. Tonic vagal tone was higher in the natural environment than the classrooms, but no differences were found in event or phasic vagal tone or cognitive performance measures. These findings suggest a situational aspect of the conditions under which natural environments may give rise to stress-buffering influences. Further research is warranted to understand the potential benefits in a real-life context, in particular with respect to the underpinning mechanisms and effects of accumulated exposure over time in settings where children spend large proportions of time in natural environments.

Caring collectives and other forms of bystander helping behavior in violent situations

Social science research has traditionally described bystanders in violent emergencies as being passive. Recent evidence, however, stresses that bystanders typically intervene proactively and successfully in violent, dangerous emergencies. This article examines the multiple ways bystanders act in situations of violence, with the aim of moving beyond the understanding of bystanders as being either passive or active. Based on a qualitative analysis of surveillance camera recordings of urban public assaults, the study maps different types of bystander behaviors as they unfold in real-life violent events. The first part of the analysis is summarized in a typology that covers three types of bystander action: distancing, ambivalence, and involvement. The second part shows that the involvement action also unfolds through coordinated interactions between the bystanders, what the article characterizes as a ‘caring collective.’ This interactional aspect of bystander involvement has rarely been examined in the bystander literature, which tends to focus on individual bystander actions and motivations.
