团体决策支持系统和团体讨论对团体决策的影响

通过模拟实验的方法,探讨了团体决策支持系统（GDSS）和团体讨论对团体决策的影响。以大学生为被试,运用小组决策任务,对小组决策过程进行了研究。实验记录了在有无GDSS的支持和有无团体讨论两个变量所决定的4种实验条件下,小组决策取得结果的正确性和组内的一致性。用ANOVA方法分析了4种条件下的实验结果,发现GDSS能提高团体决策的正确性,而团体讨论将有助于成员做出一个正确的、一致的决策     

Autobiographical Memory Retrieval and Problem-Solving Deficits of Iranian Depressed Patients Attempting Suicide

The underlying hypothesis was that suicide attempters tend to retrieve overgeneral autobiographical memories, with a considerable latency. Two cognitive measures (Autobiographical Memory Test and Means-Ends Problem-Solving Task, Persian versions) were used to assess 20 suicide patients who met DSM-IV criteria for depression, in comparison with a matched control group. The results showed that the suicide attempters produced more overgeneral memories and responded more slowly to positive than negative cue words, compared to the control participants. In the problem-solving task, the depressed patients evidenced less effective strategies, fewer and more irrelevant means, and took longer to respond to the task than the matched healthy participants. Moreover, there were significant correlations between autobiographical memory and problem-solving variables.     

An argument game for stable semantics

In this paper, we present a discussion game for argumentationunder stable semantics. Our work is inspired by Vreeswijk andPrakken, who have defined a similar game for preferred semantics.In the current paper, we restate Vreeswijk and Prakken's workusing the approach of argument labellings and then show howit can be adjusted for stable semantics. The nature of the resultingargument game is somewhat unusual, since stable semantics doesnot satisfy the property of relevance.     

通过样例和问题求解学习物理──加强对条件的认知

这项研究支持了我们先前的研究结果,即知识可以表征为一组产生式规则,产生式规则的学习可以通过考察样例和通过问题求解的方式进行。这项研究特别探讨了加强对于产生式的条件认知加工活动的效果。结果表明了我们这一构思的有效性。此外,还讨论了这一学习模式的学习过程。     

初中学生问题解决能力发展的跨文化研究

本研究采用多因素实验设计。实验中的问题是初三教学涉及的电阻定律,要求学生自己动牧比较抽象概括来解决问题。通过方差分析考察诸多因素对问题解决水平的影响。结果表明：初中学生解决问题能力的水平有多个层次,目前约有６５％的初中生面对较复杂问题无法进行较好的抽象概括,但有针对怀的启发对问题解决有明显遥促进作用;学生的年龄、智力、学绩、教学方式和社会文化环境影响着问题解决的水平。     

Juggling Multiple Roles and the Act of Resistance

This article addresses some ways mothers cope with the multiple stresses associated with their dual roles as workers and primary family caregivers. During the often stressful family life-cycle when adolescent children are individuating, a mother's active resistance can call attention to her need for support and validation of her efforts. While both parents are in the process of negotiating the intricate balance between letting go and forming new collaborative relationships with their soon to be adult children, heavy responsibilities associated with the maternal role can be especially challenging. In addition to gender-sensitive family interventions, mutual support groups for women who parent can help explore ways to effectively respond to cross-generational conflicts and problem solving.
