数学学业不良初中生的工作记忆特点：领域普遍性还是特殊性?

研究选取上海111名(男生48名, 女生63名, 平均年龄11.97岁)初中学生(数学学业不良学生55名与数学学业优秀学生56名), 根据国家数学课程标准, 将数学划分为数与代数、空间与几何两部分, 又从空间与几何领域中选取初一数学学业知识点—— 轴对称和中心对称图形, 分析在不同内容知识领域的解答过程中所涉及的工作记忆成分。结果发现：(1)数与代数学习需要中央执行系统、视觉-空间模板、语音环路三个成分的共同作用; 空间与几何学习主要受到视觉-空间模板和中央执行系统的影响, 但不存在语音环路的影响。(2)对轴对称与中心对称图形任务的成绩影响最大的是视觉-空间模板, 其次是中央执行系统, 语音环路对该任务作用不明显。两个研究说明工作记忆在初中不同年级的各类数学学业任务中具有不同的作用, 中央执行系统和视觉-空间模板相对更具有普遍性作用, 语音环路具有特殊性作用, 并且随着年龄增高, 视觉－空间模板对数学学业任务的作用更为突显。     

Main and interactive effects of social support in predicting mental health symptoms in men and women following military stressor exposure

Abstract

Evidence across a multitude of contexts indicates that social support is associated with reduced risk for mental health symptoms. More information is needed on the effectiveness of different sources of support, as well as sex differences in support. Associations between social support from two sources – the military unit and friends and family – and mental health symptoms were examined in a study of 1571 Marine recruits assessed at the beginning and end of a highly stressful 13-week training program. Military social support buffered the stressor exposure–posttraumatic stress symptomatology (PTSS) relationship, whereas the relationship between stressor exposure and PTSS was highest when civilian social support was high. Further inspection of the interactions revealed that military support was most important at high levels of stressor exposure. Sex differences in the relationship between social support and symptoms were found, such that support from military peers was associated with lower levels of PTSS for men, whereas civilian support was associated with lower PTSS for women. While civilian social support was associated with lower levels of depression symptom severity in both women and men, the relationship was stronger for women. Reviewed implications focus on the importance of considering the recipient, source, and context of social support.     

Sexual Harassment and Posttraumatic Stress Symptoms among Asian and White Women

Sexual harassment is a prevalent problem that has been associated with negative psychological and physical health outcomes. Although sexual harassment has been linked to posttraumatic stress (PTS) symptoms, little is known about how PTS symptoms that arose from sexual harassment experiences might be associated with psychological and physical health. This study examined the associations among sexual harassment, PTS symptoms, and psychological and physical well-being in a sample of Asian and White women. In addition, given the lack of research on sexual harassment among Asian women, we investigated the moderating role of ethnicity. Results indicated that greater sexual harassment frequency and PTS symptom severity predicted more depression, overall psychological distress, and physical symptoms. PTS symptom severity and ethnicity moderated the relationship between sexual harassment frequency and physical symptoms. We discuss the implications of these findings and directions for further research.     

Community-Based Interventions in New York City After 9/11

Abstract

The horrors of 9/11 have created tremendous psychosocial needs in the population of New York. For all major providers in this field, this has meant taking up the challenge of learning within the new situation, creating new frameworks for intervention, and implementing programs that previously had not been a part of the traditional social services environment. In this article, we will describe the process of transforming this challenge into an opportunity for organizational, professional and conceptual growth.     

Attributions for Different Types of Traumatic Events and Post-Traumatic Stress Among Women

This study investigated the relationship of attributions to post-traumatic stress symptoms among women exposed to different types of traumatic events. Participants were 424 female undergraduates who previously experienced a serious accident, natural disaster, child abuse, or adult interpersonal violence. Path analysis indicated a significant indirect pathway from event type to post-traumatic stress through global attributions. Interpersonal-violence survivors exhibited the highest levels of global attributions and post-traumatic stress symptoms. Regression analyses revealed significant interactions between event type and attributions in predicting post-traumatic stress. Stable attributions were associated with increased symptoms in sexual-assault survivors and decreased symptoms in natural-disaster survivors. These findings have implications for improving cognitive interventions for survivors of different types of traumatic events.     

Toward a Public Mental Health Approach for Survivors of Terrorism

Abstract

Although most people exposed to bioterrorism or mass casualties will be extremely distressed during the immediate aftermath, only a minority (approximately 30%) will develop clinically significant psychiatric disorders. From a public mental health perspective, the challenge is to provide both preventive programs for the entire population and early detection and intervention for those at greatest risk for PTSD or other post-traumatic psychiatric disorders. Both individual and soci-etal preventive and early intervention approaches are reviewed. Utilization of the media, especially television, is presented as an example of one of many potential community/societal public mental health approaches.     

The Primary Care Health System as a Core Resource in Response to Terrorism

Abstract

Living through a terrorist event or under threat of attack affects both mental and physical health. A nation's primary care system plays a critical role under such circumstances. This article reviews the American experience after September 11, 2001 and advocates for integration of mental and physical health services in primary care settings as a key counter-terrorism strategy. Americans put their trust in primary care providers. The nation's healthcare system must develop and implement a strategy that informs and supports primary care providers in meeting the mental health needs of a nation confronted by terrorism.     

Community Mental Health in Emergencies and Mass Disasters

Summary

Mass disasters are widespread and intensive, affecting individuals, families, communities, society, and culture. Mental health services must play a crucial role in order to meet non-routine challenges that put basic professional issues to the test both in theory and in practice. In the Tel Aviv Model, responsible planning is based on a broad system of mediators and activities during normal times, supplemented by intervention personnel and techniques set in motion during emergencies. This operation is coordinated with municipal and governmental support systems, which must be aware of the importance of comprehensive and flexible emergency systems for treating the population.     

Impact of Workplace Bullying on Emotional and Physical Well-Being: A Longitudinal Collective Case Study

Bullying and mobbing are occupational safety hazards pervasive in developed and developing countries. Our study aim was to determine whether bullying and mobbing caused poor health for a victim and a witness from the same workplace in western Canada. Longitudinal semistructured interviews were conducted in 2007 and 2008 with both parties. The interviews were transcribed, analyzed, and arranged into arrays using chronological ordering and time sequencing. The victim felt targeted because she represented a threat to the bully, with victim and witness experiencing negative health outcomes. The authors suggest that wellness programs should place greater emphasis on mental health promotion to discourage workplace bullying.     

Social Responsibility and the Mental Health Professions

Summary

While mental health professionals tend to primarily focus on their professional responsibilities toward the specific members of the public whom they serve, many are also concerned about positively impacting the broader society or culture in which they live and work. This notion of social responsibility is addressed in the ethics codes of both psychologists and social workers. This article reviews how this notion is addressed for these two mental health professions and also examines the changes that have occurred for psychologists between the 1992 and 2002 ethics codes. Finally, some general issues regarding the role of mental health professionals in changing society are considered.
