器官移植手术中的医患利益冲突

我国的器官移植手术得到超常发展的重要原因是走了捷径,海归医学人士为我国器官移植手术的开展做出了贡献。但器官移植发展“喜忧参半”。手术背后有医患之间的利益冲突。科学利益和经济利益至上给器官移植的健康发展蒙上阴影。必须加强器官移植的法规建设和管理监督,使我国的器官移植更符合伦理的要求。     

Adolescent Report of Interparental Conflict: The Role of Threat and Self-blame Appraisal on Adaptive Outcome

Research consistently shows that children exposed to interparental conflict are at-risk for experiencing psychopathology. Establishing a link, however, between interparental conflict and maladjustment is not the same as understanding how specific outcomes manifest. Therefore, we examined the relation of interparental conflict and appraisal with adolescent outcome with 169 high school students (ages 14–19 years). Specifically, threat and self-blame appraisals were hypothesized to mediate the relation between interparental conflict and both adaptive and maladaptive outcomes. Results suggest that threat partially mediated the relation between interparental conflict and externalizing problems, interparental conflict and internalizing problems, and interparental conflict and adaptive behaviors. Additionally, self-blame appears to partially mediate the relation between interparental conflict and internalizing problems. Implications of the current findings are discussed.     

注意缺陷多动障碍儿童在不同加工阶段的干扰控制

采用刺激－刺激和刺激－反应相容性任务范式,将信息加工在知觉和反应阶段的冲突效应分离开来,考察注意缺陷多动障碍（Attention Deficit Hyperactivity Disorder,简称ADHD）儿童在知觉和反应阶段冲突控制的模式和时间轨迹。结果发现,在反应阶段,ADHD儿童的干扰控制能力明显弱于正常对照组儿童,混合型ADHD儿童的能力更弱于注意缺陷型ADHD儿童;在知觉阶段,ADHD儿童没有明显的干扰抑制缺损,两组ADHD儿童（注意缺陷型和混合型）的表现模式相似;儿童抑制冲突干扰所遵循的时间轨迹在知觉和反应阶段有所不同：与知觉阶段相比,反应阶段需要更长的时间才能抑制冲突干扰。但ADHD儿童和正常儿童之间的表现模式相似     

Psychophysiological evidence of response conflict and strategic control of responses in affective priming

This experiment investigated the role of conflict in the response and evaluative categorization systems in the affective congruency effect using event-related brain potentials (ERPs). Participants completed a primed evaluative decision task in which the proportion of congruent to incongruent trials was manipulated. The size of the affective congruency effect increased along with the proportion of congruent trials. ERP data identified the locus of this effect in the response system: the lateralized readiness potential (LRP) showed that preferential response activation occurred in motor cortex following prime onset, and the fronto-central N2 (conflict monitoring) component indicated that conflict occurred when the response activated by the prime differed from the target response, irrespective of the affective congruency of the prime and target. The extent of this conflict covaried with strategic processing of primes, as participants directed less attention to primes that were likely to elicit conflict. These data support a response conflict account of affective congruency effects in the evaluative decision task and indicate that strategic control of attention is important in determining the extent to which conflict occurs.     

冲突与支持影响情侣依恋的文化差异

采用香港和美国的被试,运用亲密关系经历量表、冲突量表和社会支持量表,考察了冲突和支持对于情侣依恋影响的文化差异。结果发现,当以依恋焦虑为因变量时,冲突、支持和文化 × 冲突 × 支持都是显著的预测变量;当以依恋逃避为因变量时,仅文化和文化 × 支持是显著的预测变量。由此可见,文化影响冲突 × 支持与依恋焦虑的关系：在香港,情侣之间的冲突和支持各自对于依恋焦虑的作用在很大程度上相互抵消;在美国,情侣之间冲突的负面影响比支持的积极影响要强,冲突 × 支持越高,依恋焦虑越高。对于依恋逃避,文化差异仅调节支持与依恋逃避的关系：在香港,支持对依恋逃避的影响要比美国强。整个研究表明,对不同类型的情侣依恋,文化的调节作用不同。     

目标取向与社会认知冲突调节的关系

本研究采用问卷法考察目标取向与社会认知冲突调节的关系.结果表明:任务取向对认识冲突调节有显著的正向预测作用;趋向型自我取向对关系冲突调节有显著的正向预测作用;逃避型自我取向对社会认知冲突调节无显著的预测作用;社会认知冲突调节的直接与间接测量方式具有等价作用.     

婚姻冲突、应对策略及其与婚姻满意度的关系

探讨婚姻冲突、应对策略、婚姻满意度的特点及其关系。采用方便取样,选取辽阳市已婚完整家庭1～10年的夫妻620对进行问卷调查。结果表明：1）夫妻报告的前三项冲突是：家务琐事、不良习惯和交流解决问题方面。在家务琐事、交流解决问题和孩子方面,妻子报告的冲突显著多于丈夫;妻子报告的双方回避应对显著多于丈夫;2）人际关系冲突和工作方面的冲突分别对妻子和丈夫的婚姻满意度有显著预测作用;双方都报告人际关系方面的冲突对对方婚姻满意度有显著预测作用,但妻子报告的人际关系冲突对丈夫婚姻满意的预测作用更大;3）自己和对方的应对策略在妻子报告的冲突与婚姻满意中起完全中介作用,在丈夫报告的冲突与婚姻满意中起部分中介作用。     

Parental Depression and Child Externalizing and Internalizing Symptoms: Unique Effects of Fathers’ Symptoms and Perceived Conflict as a Mediator

Although a developing body of literature suggests that depressive symptoms in fathers are related to child psychopathology, little evidence suggests that paternal depression plays a unique role in children’s symptoms. We used a high-risk design involving children of mothers with and without histories of depression to test the unique mediating role of father–child conflict in the relations between fathers’ depressive symptoms and child externalizing and internalizing symptoms. In all regression analyses, mothers’ history of depression and current depressive symptoms were controlled. Depressive symptoms in fathers were associated with child externalizing and internalizing symptoms, and father–child conflict. Father–child conflict mediated relations between fathers’ depressive symptoms and child externalizing symptoms above and beyond the effects of maternal depression history and depressive symptoms. The results suggest that negative interpersonal consequences of parental depression on child psychopathology may not be limited to mothers.     

团队内冲突对团队效能的影响及作用机制

冲突是团队有效运作面临的主要挑战之一。学术界关于冲突与团队效能关系的研究结论未能达成共识, 引发了关于冲突对团队效能作用机制的探讨。回顾国内外相关文献发现, 团队特征(团队情绪、多元化、团队规范与文化价值观)、团队过程(冲突管理、信任)及任务特征等因素, 对于冲突对团队效能的作用过程具有调节作用。而基于冲突原因视角探讨团队内冲突对团队效能的影响、冲突的动态性、团队新成员冲突的激活效应和冲突与团队效能关系的本土化研究等应是未来的研究方向。     

强迫症病理的认知–行为研究述评

认知–行为领域对强迫症(OCD)的病理进行了深入的探索。强迫症的认知–行为理论认为功能失调性信念、应对策略及中和行为对强迫症的发生和维持有重要作用; 强迫症的安全动机模型把强迫行为归因于安全动机系统不能产生停止安全防卫行为的信号, 在此基础上有研究表明, 在做停止强迫行为的决策时, 强迫症患者依赖于主观停止标准, 导致决策困难, 延长了强迫行为持续的时间。通过整理近年来此领域的研究, 认为趋–避冲突存在于一些强迫症患者中, 且可能是导致强迫症的又一重要因素。
