公安民警的创伤后应激症状对执行功能的影响—基于Stroop范式的探究

公安民警常常身临应激和危险情境中,是创伤事件的易感人群,但其创伤后应激症状对执行功能的影响研究尚且缺乏。已有研究发现,具有创伤后应激症状的个体的执行功能存在缺陷,表现在对冲突信息的抑制能力受损以及对创伤相关信息的注意偏向和情绪唤起。本研究以公安民警为实验组被试,据其创伤后应激症状分为高低两组,在校大学生为对照组被试,采用Stroop范式探究创伤后应激症状对公安民警“冷”、“热”执行功能的影响。结果表明,具有创伤后应激症状的公安民警在“冷”、“热”执行功能上不存在缺陷,但仍在一定程度上受到创伤后应激症状的影响。启示对具有创伤后应激症状的公安民警进行干预时,应关注其症状的严重程度,在“热”执行功能上寻求更有效的干预方式。     

Psychological disaster myths in the perception and management of mass emergencies

Disaster myths are said to be widespread and consequential. However, there has been little research on whether those involved in public safety and emergency response believe them. A survey examined how far police officers, civilian safety professionals, sports event stewards and comparison samples from the public believe the myths “mass panic,” “civil disorder,” and “helplessness.” Respondents endorsed the first two myths. However, they rejected the myth of helplessness and endorsed the view that emergency crowds display resilience. Despite these contradictions in stated beliefs, there was also evidence of ideological coherence: each model of mass emergency behavior (maladaptive vs. resilient) was linked to a model of crowd management (coercive and paternalistic vs. mass‐democratic). The practical implications of these findings are discussed.     

Weapons and Eye Contact as Instigators or Inhibitors of Aggressive Arousal in Police-Citizen Interaction1

A field experiment was conducted with police officers during the normal course of their traffic patrol duties. The purpose was to determine whether the presence of holstered weapons and mirror sunglasses affected the degree of aggressiveness expressed nonverbally, and reported on a mood scale by citizens halted for an information check (neutral condition) or in order to be given a traffic ticket (negative condition). Results indicated that subjects in the negative condition both expressed and reported more aggressivity when the police officer wore a weapon than when no weapon was visible. The use of sunglasses had no effect on aggressivity but resulted in the officer's being perceived more negatively, though he was not perceived more negatively when he wore a weapon. No sex differences in expressed or reported aggressivity were obtained, although some sex differences on measures of secondary interest did occur. The implications of these findings for research on the “weapons effect” and on policy regarding the visibility of police weapons and the wearing of sunglasses by police officers are discussed.     

American and Danish police “dropout” rates: Denmark's force as a case study in high job satisfaction,low stress,and low turnover

An excessive “dropout” rate among police officers—quitting prior to normal retirement—wastes resources and may result in a low level of experience. Denmark's police force appears to be a case study in low turnover and may provide valuable insights. A primarily qualitative analysis contends that factors related to Danish culture and police practices produce relatively low stress and high “need fulfillment” for Danish officers in comparison with their counterparts in typical U.S. police departments—variables previously found related to low turnover. Results of a mail questionnaire show rates of early leaving (prior to retirement) notably lower for the Danish police than for a U.S. national sample of 87 police departments in large cities, and a special subsample of 39 small-city departments in California. Qualifications and implications are discussed.     

On being mindful,emotionally aware,and more resilient: Longitudinal pilot study of police recruits

Police officers are at particular risk of stress when compared to people in other occupational groups. A compounding factor is that police are prone to the use of avoidant coping strategies when attempting to deal with this stress. Evidence suggests that “anti‐avoidance” strategies, of acceptance, mindfulness and emotional awareness, are more effective ways of coping, and are linked to both mental health and personal effectiveness. This study followed 60 trainee police officers from the recruit phase into the workplace to determine if these processes predicted more positive mental health and wellbeing in police recruits after 1 year of service. Mindfulness predicted depression at follow‐up, while emotion identification skill predicted general mental health. These results suggest that police officers and police organisations may benefit from interventions aimed at developing and promoting mindfulness and emotion identification.     

Identification from CCTV: Assessing police super‐recogniser ability to spot faces in a crowd and susceptibility to change blindness

Police worldwide regularly review closed‐circuit television (CCTV) evidence in investigations. This research found that London police experts who work in a full‐time “Super‐Recogniser Unit” and front line police identifiers regularly making suspect identifications from CCTV possessed superior unfamiliar face recognition ability and, with higher levels of confidence, outperformed controls at locating actors in a bespoke Spot the Face in a Crowd Test. Police were also less susceptible to change blindness errors and possessed higher levels of conscientiousness and lower levels of neuroticism and openness. Controls who took part in Spot the Face in a Crowd Test actor familiarisation training outperformed untrained controls, suggesting this exercise might enhance identification of persons of interest in real investigations. This research supports an accumulating body of evidence demonstrating that international police forces may benefit from deploying officers with superior face recognition ability to roles such as CCTV review, as these officers may be the most likely to identify persons of interest.     

Prejudice in the police: On the processes underlying the effects of selection and group socialisation

The principal aim of this study is to determine why police officers are generally found to be more prejudiced towards disadvantaged groups than are the standard population. Two independent processes were expected to account for this effect: Selection and group socialisation. Using a cross‐sectional design (N = 170), firstly, we compared, newly recruited police officers with a control population (selection effect), and secondly, police officers with 1 year of training with the newly recruited ones (group socialisation effect). Results reveal a significant effect of both selection and group socialisation, the two being underlined by distinct processes; right‐wing authoritarianism (RWA) in the case of the former and internalisation of a prejudice norm in the case of the latter. Finally, the results show that group identification moderates the change in internalisation of the prejudice norm. Copyright © 2009 John Wiley & Sons, Ltd.     

Cognitive models of stereotype change: (1). Generalization and subtyping in young people's views of the police

We report investigations of change in, and cognitive representation of young people's stereotypes of the police, in response to a police-schools liaison programme. This programme provides a real-life application of the ‘conversion’ model of stereotype change (in which stereotypes change radically in response to salient instances of disconfirming information). Study 1 revealed that school police officers were rated significantly more positively than the police in general, but that this view did not generalize to perceptions of the police in general. Stereotypes of the police became less positive over one year, although females were more positive than males, and school police officers were not judged typical of the category. Study 2 revealed that subjects categorized their school police officer separately from the police in general, and perceived him to share features with ‘caring and welfare’ professions, rather than other police officers and authority figures. Both studies converge on the limitations of the conversion model and tend to support the subtyping model (in which extremely disconfirming individuals are isolated from other group members).     

Policing the Ivory Tower: Students’ Perceptions of the Legitimacy of Campus Police Officers

Policing research has largely overlooked how college students’ perceptions of the legitimacy of campus police officers can be enhanced and diminished. Using data from interviews and focus groups with students and staff, along with data from two field observations, this article finds that although students expect the campus police to protect them from harm, they believe that officers should fulfill this function while not interfering with their lives as college students. Further, students delegitimize the power of the campus police by raising questions about their status as “real” officers and highlighting how they overreact to the wrong types of behaviors.     

Pre-operative transgender motivations for entering policing occupations

This article examines the motivations for American, English, and Welsh transgender motivations for entering policing. Historically and empirically, policing has been documented as a social environment where binary gendered ideologies are strictly enforced and upheld. Further, scant research on transgender perceptions of the police have highlighted fear of sexual assault, fear of arrest, heightened levels of police violence, and general uncomfortableness with interactions with the police. This article argues that instead of avoiding a perceived volatile binary gendered environment, pre-transition transgender identities seek out policing due to hyper masculine expectations of the job itself. I argue that MtF (male-to-female) and FtM (female-to-male) pre-transition transgender identities seek refuge within the hyper masculine environment of policing to ease internal conflicts as a result of gender dysphoria (i.e. pre-transition distress) prior to transition. In this study, 13 transgender police officers from America, England, and Wales were interviewed about their motivations for entering policing. This study found that a majority of male-to-female (MTF) and female-to-male (FTM) transgender identities chose to enter policing due to gender distress pre-transition. This research found that pre-transition people with MtF trasngender identies chose to enter policing to combat their gender dysphoria by proving their "masculinity," and people with FtM transgender identities enter policing to foster and embrace their “masculinity.”     

Embracing Change: Further Examination of a “Capabilities and Benevolence” Beliefs Model in a Military Sample

Building on earlier research that used a “capabilities/benevolence” framework to examine an “embracing change” disposition, the current investigation extended previous cadet-based findings to a sample of company- and field-grade military officers. We hypothesized that officers with a high learning orientation and a high propensity to trust others would hold a significantly more positive attitude toward change than other individuals, even when controlling for the officer's general dispositional resistance to change. As with the earlier cadet results, the findings confirmed the hypothesis for learning orientation but not for trust. Discussion focused on the utility of acquiring a better understanding of an embracing change disposition and on the value of salting individuals with high learning orientations throughout the organization. Additionally, for future research, we consider the importance of employing multiple and diverse methods when exploring the embracing change construct. Such methodological expansion will undoubtedly reduce some conceptual ambiguities associated with the current study.     

Police-Public Interactions: The Impact of Conflict Resolution Tactics1

Following Hammock and Richardson (1992), it was hypothesized that a preference among some police officers for confrontational rather than conciliatory tactics when dealing with the public may serve to escalate a conflict and thereby explain the documented individual differences in reports of officer assaults. In order to test this possibility, preferred conflict tactics and officers' recent experiences of citizen compliance (and non-compliance) were measured for a sample of 115 English police and 48 Australian police. The results supported the hypothesized relationship by indicating a significant correlation between preferences for specific confrontational and coercive tactics and experiences of noncompliance from the public.     

Quality of written record following mock eyewitness testimony: Note taking should be a minimum standard!

By using a video‐based narrative (unidirectional) eyewitness statement of an alleged victim, participants were asked to imagine they were police officers. We compared the quality of mock police officer written records in a between‐subjects design comprising three conditions: (a) a free recall (n = 27), (b) a free recall by using recall strategies of the cognitive interview (n = 27), or (c) note taking while watching the video (n = 26). The quality of the reports was determined by the amount of correctly recalled details, omitted details, added details (commission errors), and changed details (confabulations). As predicted, the number of correct details was higher in the “Note Taking” condition whereas performance in the “Free Recall” and in the “Cognitive Interview” conditions did not differ. Higher verbal memory ability resulted in a better quality of the written records. Our results suggest that note taking facilitates the quality of written records.     

Police and prosecution systems: An evaluation of a police criminal case preparation program

Program evaluation can provide objective information relevant to decisions on program maintenance. A program to address problems in the preparation of criminal investigation reports in a metropolitan police department was evaluated. The program permanently altered environmental conditions under which reports were prepared to facilitate performance. Police officers, who had previously prepared reports without assistance, visited the Case Preparation Room to prepare reports with assistance from office personnel. Compared to reports prepared without assistance, reports prepared in the Case Preparation Room documented more case elements required by the state legal code for criminal prosecution, were completed in fewer days following arrests, and received higher ratings from Assistant District Attorneys. Operation of a permanent program available to approximately 945 officers proved a practical solution to improving the preparation of criminal investigation reports.     

“I'm a police officer not a social worker or mental health nurse”: Online discourses of exclusion and resistance regarding mental health‐related police work

Despite estimates suggesting that around 15% of UK police incidents involve people with a mental health concern, officers receive very little mental health training. The police have faced high‐profile criticisms over their handling of mental health‐related incidents, whereas the underfunding and fragmentation of UK mental health services has led to concerns that police officers are being forced to undertake a primary role in mental health care. At a time of austerity and widespread cuts to public services, it is important to explore how particular groups work to justify the parameters of their professional duties. This article therefore explores the discourses surrounding mental health problems on an online police discussion forum, highlighting two distinct ways in which mental health‐related work is represented as being incompatible with policing. First, mental health problems are delegitimised and conflated with “scrounging,” positioning individuals as undeserving of police time; second, mental health problems are reified and associated with violence and extreme behaviour, justifying the use of force by police officers and deflecting responsibility onto mental health services. Findings are consistent with previous research suggesting that mental health work is not perceived to be a valid part of the police role.     

The Role of Police Perceptions and Practices in the Development of “Public Disorder”1,2

Recent studies suggest that crowd conflict needs to be understood as an interaction between the crowd and out‐groups such as the police. This paper describes a questionnaire survey in which 80 police officers from 2 United Kingdom forces were asked about their perceptions of crowds, appropriate “public order” policing methods, and attributions of responsibility for crowd conflict. As predicted, police officers saw the composition of crowds as mixed; yet they also constructed a dichotomy between a powerful minority, capable of exerting influence in the service of disorder, and a majority, who are unable to resist this influence. Police officers did not clearly endorse the view that crowds pose a homogeneous threat. They recommended control and quick intervention to prevent the escalation of crowd violence but denied that such methods might themselves contribute to conflict. Path analysis provides suggestive evidence that these perceptions of the crowd are related as part of a coherent ideology. Overall, these results offer support for the elaborated social identity model of crowd behavior as a dynamic intergroup process.     

Appraisal and coping processes in acute time-limited stressful situations: A study of police officers

This study focuses on the appraisal and coping process in acute, time-limited stressful situations in a stress experienced group: 54 Swedish police officers. Each police officer retrospectively reported their thoughts, emotions, and actions during five recent stressful job events. The relations among appraisals of threat and of coping options, seven forms of problem- and emotion-focused coping strategies, and selfrated performance were examined. Compared with previous studies of ordinary people in stressful situations, the police officers felt less threatened, appraised the situations as more solvable, and used considerably more problem-focused forms of coping. Age had a significant effect on appraisal, while organizational position had a significant effect on coping. Using latent profile analysis, four appraisal styles were obtained. Consistency of cross-situational appraisal style amongst individuals was high. The functional relationships among variables, i.e. appraisal, coping, and performance, are discussed.     

Getting narced: Neutralization of undercover identity discreditation

“Communicative work directed to transforming an individual's total identity into an identity lower in the group's social types is called a ‘status degradation ceremony'” (Garfinkel 1956, p. 420). Status degradation ceremonies are particularly troublesome for undercover narcotics agents. In this context, they act as the mechanism by which agents’ dissembled identities are questioned and their real police ones revealed. This process, what officers call “getting narced,” is the topic of the present paper. Explored here are both its causes and the responses officers proffer to neutralize full identity exposure. Causes are tactical in nature and involve transactional overaggressiveness. Neutralization responses are dramaturgical in nature and involve sarcastic admission, evidential refutation, and belligerent denial/threatening retort. Discussion focuses on the conceptual implications of officers’ counteruncovering moves (Goffman 1969) as these relate to the sociology of accounts (Scott and Lyman 1968). Data were drawn from ethnographic interviews with 30 high school undercover officers operating out of a large U.S. city.     

Perceived Authoritarianism in Self and Others by Male College Students and Police Officers

This study tested 62 police officers and 62 college males on their own authoritarianism and their estimates of the authoritarian beliefs of the other group. College students perceived police officers as much more authoritarian than the officers represented themselves as being ( p < .0001). Officers were accurate in their estimations of students' authoritarianism, and there was no difference between officers and students in their characterizations of their own authoritarianism. The differences between these findings and those in much of the literature (especially that from the early 1970s) may be due to differences in police experience: Many of the officers in this sample had some college and thus direct experience with students. It may also be that officers are now being specifically chosen on the basis of less authoritarian attitudes. The results imply that rather than focusing on changing the attitudes of officers, police departments desiring better public relations might do well to concentrate on correcting public opinion.     

Why Do Police Arrest Victims of Domestic Violence? The Need for Comprehensive Training and Investigative Protocols

After all the positive changes in the criminal justice system over the last ten to fifteen years concerning the response to incidents of domestic violence, there remains the problem of battered women who are arrested as perpetrators of domestic violence. The reasons for these arrests are complex and varied. They range from the patriarchal structure of criminal justice agencies, to the staffing of these agencies, and finally to the inappropriate and inadequate training of police officers. This article includes real life examples of cases where victims were arrested, and why these arrests occurred. It also includes suggestions on how to minimize these illegal arrests.
