MAU程序和自由讨论的群体决策质量比较

采用实验室研究方法,比较了在信启、不分享条件下多特征效用模型(MAU)决策程序和自由讨论对群体决策质量的影响,并对影响MAU决策质量的主要因素进行了初步探讨。结果发现：(1)MAU程序可以较好地克服群体动力学方面的一些消极影响,表现出挖掘信息(尤其是非分享信息)的充分性。但MAU程序在被试的态度和社会交互作用等心理效标上并未显示出优势;(2)在MAU条件下,群体规模的增大对分享和非分享信息的讨论量无显著影响。而任务难度效应要和群体规模一起才能起到作用。     

A meta-analysis of bibliotherapy studies

Used meta-analysis to examine the efficacy of bibliotherapy. Bibliotherapy treatments were compared to control groups and therapist-administered treatments. The mean estimated effect size (d) of the 70 samples analyzed was +0.565. There was no significant differences between the effects of bibliotherapy and therapist-administered treatments, as well as no significant erosion of effect sizes at follow-up. Bibliotherapy did appear more effective for certain problem types (assertion training, anxiety, and sexual dysfunction) than for others (weight loss, impulse control, and studying problems). Overall, the amount of therapist contact during bibliotherapy did not seem to relate to effectiveness, but there was evidence that certain problem types (weight loss and anxiety reduction) responded better with increased therapist contact. Recommendations for future research were given, especially for more research on the commonly purchased books and moderator analyses by personality type and reading ability. This article is based on a doctoral dissertation by Rick W. Marrs under the direction of Steven D. Brown at Loyola University of Chicago.

The Influence of Posttreatment Mutual Help Group Participation on the Friendship Networks of Substance Abuse Patients

The effect of 12-step mutual help groups (e.g., Narcotics Anonymous) on members' friendship networks has received little attention. This 1-year longitudinal study examined such effects in a sample of 2,337 male substance abuse inpatients, 57.7% of whom became significantly involved in 12-step activities (e.g., reading program literature, attending meetings) after treatment. An a priori model of the interplay of 12-step involvement and friendship networks was tested using structural equation modeling, and found to have excellent fit to the data. Twelve-step group involvement after treatment predicted better general friendship characteristics (e.g., number of close friends) and substance abuse-specific friendship characteristics (e.g., proportion of friends who abstain from drugs and alcohol) at follow-up. Results are discussed in terms of how mutual help group involvement benefits patients and how the self-help group evaluation paradigm should be broadened.     

The Role of Problem Construction in Creative Production

This paper provides an overview of theory and research regarding problem construction and identification. Specifically, the paper reviews a theoretical model of processes associated with problem construction and empirical evidence in relation to the model. Finally, the paper reviews the literature on team problem construction.     

Re‐Operationalizing Established Groups in Brainstorming: Validating Osborn's Claims

Since the introduction of brainstorming as an idea‐generation technique to address organizational problems, researchers have struggled to replicate some of the claims around the technique. One major concern has been the differences in the number of ideas generated between established groups as found in industry versus the non‐established groups used in the laboratory. The impact of group establishment on idea quality has also been an area of interest. This study addresses these issues by using a more in‐depth induction to establish groups and testing some discrepancies in the relationship between idea quality and idea quantity using 42 three‐person brainstorming groups. Results indicate that brainstorming groups, given an adequate amount of time (10 weeks) to become established, did generate more ideas and higher quality ideas than non‐established groups. Also, a relationship between idea quality and idea quantity was found. Further discussion of results and implications follows.     

Effects of cohabitation with another female on aggressive behaviour in pregnant mice

Pregnant, nonpregnant (but mated) and virgin females were individually housed or lived with a pregnant or nonpregnant cagemate. They were subjected to a series of successive daily encounters with a male intruder, the cagemate being excluded. The most aggressive subjects were pregnant females living with a pregnant cagemate. Isolated pregnant females were as aggressive as pregnant females with a nonpregnant cagemate. Nonpregnant and virgin females were the least aggressive. Nevertheless nonpregnant subjects living with a pregnant cagemate generated higher aggressive scores than nonpregnant females living alone. The way in which a pregnant cagemate influences the aggressive behaviour of another pregnant or nonpregnant female is discussed.

Psychological Abuse Experienced in Groups Scale: Psychometric Properties of the Japanese Version

The purpose of this study was to adapt the Psychological Abuse Experienced in Groups Scale (PAEGS) for use in the Japanese population. This scale evaluates the frequency with which an individual has experienced psychologically abusive behaviors within a group. A questionnaire was administered to 130 former members of abusive groups and to a comparison sample composed of 124 former members of non‐abusive groups. The main results showed a one‐dimensional factor structure and an adequate reliability score. Significant correlations were found between the PAEGS and a group abusiveness measure, providing evidence of convergent validity. In addition, high discriminatory power was found, determining an optimal cut‐off point to distinguish between abusive experiences and non‐abusive experiences within groups. The Japanese version of the PAEGS is able to overcome limitations of previous instruments intended to assess the phenomenon, as sufficient empirical evidence is found for its use in research. In addition, it can be useful in clinical and legal contexts to assess the degree of psychological abuse experienced by Japanese people during their involvement in certain groups.     

Blurring boundaries and advancing interreligious understanding by engaging textual ‘others’ in a women’s interfaith book group

This article casts analytical light on how Jewish, Christian and Muslim women develop understanding of religious identities by engaging with multidimensional textual ‘others’ in the Daughters of Abraham interfaith book groups. It focuses on a group discussion of a rabbi’s memoir about her religious journey. Drawing on ethnographic material and Talal Asad’s analysis of the relationship between text and reader, I examine how narratives outside primary religious texts influence ideas about Jewish, Christian and Muslim identities. I argue that the Daughters members’ appropriation of literary voices advances their engagement with religious diversity by developing understanding of religious self and others. Moreover, members’ navigation of inter- and intra-religious relations during discussions of texts blur boundaries for inclusion into this interfaith encounter. This examination raises questions about issues of identity, power dynamics and interfaith relations. Importantly, it provides novel insight into the understudied areas of women’s interreligious encounter and shared reading practices.     

Police responses to diversity: A social representational study of rural British policing in a changing representational context

In the first decade of the 21st century, British policing faced two new challenges in how it responded to social diversity: As well as instituting reforms in response to a highly publicized report describing the British police as ‘institutionally racist’ (Macpherson, 1999 ), they faced challenges associated with rapid increases in numbers of immigrants into the UK. Studying social representations at such times of change allows access into processes, themes and value systems that may otherwise remain hidden. This paper uses social representations theory to explore interview accounts provided by regular police officers of interactions with members of minority groups. Empirically, we focus on an area of diversity policing that has received relatively little previous attention: Police work in a rural context that has recently played host to large numbers of migrant workers. Our analysis shows that interviews operate as a site of resistance in which respondents attempt to rework hegemonic representations of the police as prejudiced and to re‐present themselves and their work as able to respond appropriately to diversity. Fairness as a defining characteristic of good police practice is a central representational theme that links identity construction processes to police work with minority groups. Recent immigrant groups are represented as both needing and deserving help to assimilate into British culture: Their lack of acculturation and language difficulties provide additional challenges to police work and to how this is judged as ‘fair’. We discuss the broader origins and implications of police officers' understandings of fairness and the use of social representations theory to study representational fields within organizational settings.
