小规模群体开放式与封闭式讨论任务的工作特性比较

１４个小组的大学生共６８人参加两种不同的群体工作,其中７组进行开放式问题的讨论,７组进行封闭式问题的讨论。从工作进程、工作模式和工作特点等方面记录群体工作行为：工作进程各阶段所用时间,发言的针对性,发言的连续性,说明问题的方式和深度,群体的意见分歧与支持行为和表达方式。结果表明：封闭式问题需要更多的时间澄清问题并且更多引用例子来阐述观点;讨论开放式问题多采用归纳推理而封闭式问题多采用演绎推理;无论在哪种问题的讨论中,针对个体的发言都显著多于针对整体的发言,而且人们更多地以非言语的方式而不是口头方式表示赞成。本文对以上结果在电视、电话和计算机辅助会议系统设计中的应用作了进一步讨论     

加压素对记忆巩固过程作用的研究 Ⅱ.GABA在加压素易化记忆巩固过程中作用的探讨

本文探讨了脑内GABA能神经元在加压素易化记忆巩固过程中的作用。结果表明,第三天建立实验后立即腹腔注射印防己毒素(picrotoxin,0.5mg/kg),消除了加压素对条件反应消退过程的延缓作用,而注射氨氧乙酸(aminooxy-acetic acid,20mg/kg)获得相反结果。 实验结果提示,脑内GABA能神经元可能参与了加压素对记忆巩固过程的易化作用。     

The relation between type A behavior and chronic emotional distress: a meta-analysis

A meta-analysis was conducted of studies examining the relation between Type A behavior and chronic emotional distress as measured by standard psychological scales. Aggregating across all studies, the average effect size was .27, indicating a positive association between Type A and chronic dysphoria; however, there was considerable variability in the size of the relation among studies. Partitioning by Type A measure revealed that Structured Interview-assessed Type A was unrelated to chronic dysphoric emotions; however, most of the self-report measures of Type A behavior were moderately correlated with upset. The Framingham Type A Scale and the Bortner Scale showed the strongest relations. Thus, contrary to the traditional view, Type A measured by self-report does have some emotional concomitants, although they are not in the pathological range. Also discussed are how the results bear on the proposal that the maladjusted personality confers coronary risk, the implications for reported associations between Type A and illness complaints, and for the study of the Type A as a social psychological construct.     

Chronic self-destructiveness: Conceptualization,measurement, and initial validation of the construct

Individual differences in various behaviors suggest that those who are primarily motivated by current emotional factors are more likely than those motivated by more distant cognitive considerations to engage in acts that are ultimately self-destructive. To assess and explore these behavioral differences, 12 samples of undergraduate subjects, totaling 864 (527 females, 337 males), a group of 15 businesswomen, and 111 male VA patients were used to develop a measure of this construct in a series of reliability and construct validity studies. By means of internal-consistency item analyses, two cross-validated 52-item measures of chronic self-destructiveness were constructed for males and females. Reliability was established with respect to internal consistency (alpha coefficients range from .73 to .97) and temporal consistency over a 1-month period (test-retest correlations range from .90 to .98). There is a slight drop in chronic self-destructiveness scores across age groups. Test scores were found to be positively related to external locus of control, negatively related to Type A coronary-prone behavior, and unrelated to either social desirability response set or need for achievement. Individuals high in chronic self-destructiveness, compared to those with low scores, are more likely to be in treatment for drug or alcohol abuse, to report having cheated in courses, to have had traffic violations, to report having gone through a rebellious stage in adolescence, and to postpone obtaining a medical test for cancer. Chronic self-destructiveness appears to be a personality dimension that affects behavior across a wide range of ages and situations.We wish to thank John Wapner for his assistance in obtaining data in the clinical sample.     

民族文化认同与大学生职业成熟度的关系及其心理机制

为考察大学生民族文化认同与职业成熟度的关系及其内在心理机制,本研究采用多民族青少年文化认同问卷、大学生生涯自我效能感量表和大学生职业成熟度量表对4292名在校大学生进行测查,结果发现：（1）大学生的主流文化认同、民族文化认同、生涯自我效能感和职业成熟度之间具有明显的正相关;（2）主流文化认同--生涯自我效能感在民族文化认同与职业成熟度之间起链式中介作用;（3）生涯自我效能感中介民族文化认同与职业成熟度的关系在男生样本中不显著而在女生样本中显著;主流文化认同、生涯自我效能感分别单独中介民族文化认同与职业成熟度的关系在汉族大学生样本中为部分中介,而在少数民族大学生样本中为完全中介。     

Enhanced perceptual priming for neutral stimuli in a traumatic context: A pathway to intrusive memories?

Clinical observations suggest that re-experiencing symptoms are triggered by stimuli that are perceptually similar to those present shortly before the trauma or its worst moments. Two experiments investigated the possible role of perceptual priming in this phenomenon. Volunteers (N = 28, N = 62) watched a series of “traumatic” and neutral picture stories, and completed blurred object identification (priming) and recognition memory tasks. Neutral objects that immediately preceded the “traumatic” stories were more strongly primed, but not better recognised, than objects from neutral stories. Enhanced priming predicted subsequent re-experiencing symptoms. The results support the role of perceptual priming in re-experiencing.     

共患难,更同盟:共同经历相同负性情绪事件促进合作行为

4项实验探讨了共同经历相同负性情绪事件,相比单独经历负性情绪事件,是否以及如何促进了个体间的合作。实验1~3分别采用抽奖任务和瑞文推理测验任务操纵负性情绪事件,采用公共物品博弈任务测量合作行为,结果表明,共同经历相同负性情绪事件,相比单独经历负性情绪事件,促进了个体间的合作行为。实验2通过测量归属需要、社会联结和内群体认同,实验3通过操纵归属需要,来考察共同经历相同负性情绪事件促进合作行为的潜在机制,结果表明,共同经历者之间的合作行为受归属需要的驱动,而社会联结和内群体认同不足以对该现象进行解释。实验4通过操纵个体共同经历“相同”和“不同”的负性情绪事件,进一步厘清了,促进个体间的合作是由于“共同经历相同的负性情绪事件”而非“共同经历负性情绪”造成的。研究结果有利于解释小群体的形成,对群体和社会管理亦具有借鉴意义。     

社会决策中的公平准则及其神经机制

社会决策中的公平准则一直受到广泛的关注,经济学家和心理学家们分别从动机和认知的角度对这个课题进行了深入探索.在这些工作中,最为突出的是“均等”,“互惠”和“情绪”三个模型的提出.均等和互惠模型试图从动机角度理解个体的公平行为,而情绪模型则更强调个体在公平决策中的认知和情绪的加工过程.近年来脑成像的研究也为这些模型提供了相应的支持,其中与公平准则最密切的脑区是脑岛和背外侧前额叶:前者一般被认为是反映了个体面对不公平待遇时的负性情绪体验;而后者主要负责决策过程中的抑制控制.但这些脑区具体的功能还存在很多争议,反映了不同理论模型对特定脑区功能的不同理解.未来研究应注意三个模型之间的相互补充,以及加强多模态的脑指标的运用,并注重相关脑区的整体性,此外,公平决策行为中的个体差异,以及社会情境对其的影响也应受到重视.
