协作抑制的认知机制

协作抑制是指当人们在一个记忆小组中一起提取信息的时候,小组提取的信息总量比等量个体提取的信息总量要少.心理学研究者致力于从认知角度对该现象进行解释,主要的理论解释有提取策略破坏假说和提取抑制假说.前者认为小组成员的提取结果对组内其他成员的信息组织策略产生了干扰,导致小组的提取成绩低.而后者认为小组内成员的提取结果会抑制其他成员对非提取项目的表征,降低小组协作提取能力,出现协作抑制.本文对两种理论假说的提出背景,基本观点,证据支持及现有争论进行了介绍,同时指出了未来的研究应关注于对两种机制的关键矛盾点进行区别性检验、对不同认知机制在不同条件下成立可靠性的检验以及通过对编码阶段进行操控来进一步考察协作抑制的认知机制.     

Disgust sensitivity and fear of animals: Effect of exposure to violent or revulsive material

Subjects were asked to rate their fear of four categories of animals both before and after viewing one of three brief video films. Subjects watched either (a) a video depicting extreme violence, (b) a video depicting revulsive scenes from a hospital operation, or (c) a video showing neutral landscape scenes. The results suggested that exposure to violent material produced an increase in fear ratings for animals in the Hi Fear/Hi Predatory category (e.g., lion, tiger, shark) which was significantly different from a decrease in fear ratings recorded for all other categories of animals. However, exposure to revulsive material produced an increase in fear ratings to animals in both the Hi Fear/Lo Predatory category (e.g., rat, spider, snake) and the Hi Revulsion category (e.g., slug, maggot, snail) which was significantly different to the decrease in fear ratings recorded for animals in the remaining categories. The neutral landscape scenes produced a decrease in mean fear ratings for all categories of animals. These results are considered further support for a disease-avoidance model of common animal fears, and suggest a causal link between disgust sensitivity and fear of certain fear-relevant animals.     

The protective role of compassion satisfaction for therapists who work with sexual violence survivors: an application of the broaden-and-build theory of positive emotions

Therapists who work with trauma survivors, such as survivors of sexual violence, can experience compassion satisfaction while experiencing negative effects of trauma work, such as secondary traumatic stress. We examined whether the negative effects of secondary traumatic stress on therapist adjustment would be buffered by compassion satisfaction and whether the broaden-and-build theory of positive emotions could be applied to examine the factors (positive emotions and positive reframing) that relate to compassion satisfaction. Sixty-one therapists who work with sexual violence survivors completed measures of secondary traumatic stress, compassion satisfaction, adjustment, positive emotions and positive reframing. Hierarchical multiple regression analyses found that compassion satisfaction buffered the negative impact of secondary traumatic stress on therapist adjustment when adjustment was conceptualised as anxiety. Using non-parametric bootstrapping, we found that the relationship between greater positive emotions and greater compassion satisfaction was partially mediated by positive reframing. The findings indicate that compassion satisfaction is likely to be helpful in ameliorating the negative effects of secondary traumatic stress on anxiety in therapists who work with sexual violence survivors and that the broaden-and-build theory of positive emotions may provide a strong theoretical basis for the further examination of compassion satisfaction in trauma therapists.     

Innovative Approaches to Child Custody and Domestic Violence in New Zealand

Summary

In 1995, as part of a major review of domestic violence law, the New Zealand Parliament amended the legislation under which disputes about custody of and access to children are determined by the Court. Specifically, the amendment introduced a rebuttable presumption that a parent who had used violence against a child or against the other parent would not have custody of, or unsupervised access to the child unless the Court could be satisfied that the child would be safe during visitation arrangements. Three years after the implementation of this legislation, it is timely to reflect on the impact of this major domestic violence law reform initiative. Our findings indicate that there are indeed advances. Psychological violence is now clearly being considered when Courts are assessing the issue of children's safety. As well, the delineation of mandatory risk assessment factors has led many judges to see a continuum of power and control tactics as relevant in domestic violence related visitation proceedings; the previous emphasis on physical violence has given way to an analysis which more closely reflects accords with women's and children's realities of the abuse they are exposed to. Some of the old problems continue to exist despite the law changes. There are still recent cases where perpetrators of serious violence are awarded unsupervised access and where their violence continues to be construed as “out of character,” arising because of the perpetrator's “despair” about the breakdown of his relationship. These and other issues are discussed.     

Multifaceted Approaches in Spouse Abuse Treatment

SUMMARY

The understanding of spouse abuse has changed considerably in the last 30 years, shifting from a perspective based on individual psychopathology to that of a pervasive social problem. Current treatment solutions for stopping violence are limited to those that address resocializing the batterer. Several states often restrict the use of state funds for batterers' groups and forbid couples treatment as a primary treatment option in spite of the fact that most couples choose to remain in their relationships in the presence of repeated violence. This article argues for broadening options to include a specific type of couples treatment as a part of a coordinated community response to remediate domestic violence. Solution-focused therapy is described as an example of treatment of relationships that makes safety a priority and is not victim-blaming. It is suitable treatment both for couples who wish to stay together and those seeking a safe way to separate.     

What Animated Cartoons Tell Viewers About Assault

Relying upon a content analysis of one specific type of medium to which young people are exposed beginning at an early age, on a regular basis, and for many years (i.e., animated cartoons), the present study examines what types of messages are provided about violence that takes the form of simple assault. Results indicate that assault is fairly prevalent in cartoons and that this prevalence has diminished over time. Most of the time, cartoons show assaults to “land” on their intended victims, but having done so, to cause few if any adverse effects. Moreover, assaults rarely backfire on the perpetrators. Anger, revenge, and inherent mean-spiritedness are the most common reasons implied for why characters commit acts of violent assault.     

Social Services Workers and Workplace Violence

Researchers and workplace violence experts have cited risk factors that theoretically increase the likelihood that individuals will experience workplace violence. Those include working alone, contact with the public, traveling to dangerous areas, as well as other factors. By the very nature of what social services workers do, many encounter these risk factors on a regular basis. Using national data, trends in workplace violence experienced by social services workers are examined, and comparisons are made between the rates of workplace violence among similar workgroups. Results suggest that social services workers are nearly six times more likely than other workers to experience workplace violence. In the discussion, attention is given to strategies to prevent violence against social services workers.     

Do You See What I See? The Influence of Gender Stereotypes on Student and Royal Canadian Mounted Police (RCMP) Perceptions of Violent Same-Sex and Opposite-Sex Relationships

ABSTRACT

Forty-one men and 67 women undergraduate students, as well as 35 men and 27 women Royal Canadian Mounted Police (RCMP) officers, rated the abusiveness of intimate partner violence (IPV) vignettes portraying each possible gender combination of victim and perpetrator (Harris &; Cook, 1994 Harris, R. J. and Cook, C. A. 1994. Attributions about spouse abuse: It matters who the batterers and victims are. Sex Roles, 30: 553–565. [Crossref], [Web of Science ®] , [Google Scholar]). Rating differences according to victim and perpetrator gender, occupation (student or RCMP officer), and participant gender were anticipated. Analyses found that student and RCMP ratings of abuse severity were both highest for the male-female scenario. However, the RCMP considered the female-male, male-male, and female-female scenarios to be more abusive than did the students. Our findings suggest that, while the RCMP appeared to be more sensitive to male and same-sex victims than students, both groups remain somewhat biased.     

Women Court-Ordered for Domestic Violence: Improvements in Depression

A quasi-experimental design was employed to compare depression at intake and completion of a sample of primarily Latina women court-ordered to a batterer intervention program. Data were derived from the intake assessments of 112 women over 24 months. Overwhelmingly, women reported being abused by their current and former partners. Approximately 58% of the women in this sample were depressed at intake. When culturally competent, gender-appropriate treatment is given to court-ordered women, depression symptomatology may decrease to levels of normal functioning. Further research is needed to understand court-ordered women as well as how to meet their unique needs.     

Characteristics of Male Batterers in Treatment

Abstract

This article presents information on the characteristics of a clinical population of male perpetrators of intimate partner violence (IPV) court-ordered for batterers' treatment, and how these characteristics co-varied with treatment attrition. The average demographic profile of male batterers in a midwestern treatment program that met present-day treatment guidelines was similar to that found in other studies. In addition, relationship length and status, alcohol/drug use, self-reports of past treatment and mental health issues, and self-report of witnessing or experiencing violence within the home during childhood was also similar. Batterers' self-reports of their own violent behavior were found to vary by data collection technique, with face-to-face interviews eliciting greater admission of violent behavior than paper-and-pencil questionnaires. However, the only predictors of successful treatment outcome were living arrangement at the time of treatment and racial category. Implications of these findings are discussed, and “local effects” program evaluation approaches are suggested.
