任务框架及利他人格对社会折扣的影响

与自我存在一定社会距离的他人获得收益或遭受损失都会给自我带来一定的效用,这种效用随着与他人间社会距离的增加而减少,该现象被称为社会折扣。本研究采用情境式选择滴定程序,探索并比较了“为他人得益而放弃自我得益”(NG-G)、“为他人不失而放弃自我得益”(NG-NL)、“为他人得益而承担自我损失”(L-G)以及“为他人不失而承担自我损失”(L-NL)4种任务框架下的社会折扣程度。结果发现：(1)4种框架下,指数模型均比双曲模型更好地描绘了被试的社会折扣规律;(2)任务框架影响社会折扣程度,“为他人不失”框架下(含NG-NL、L-NL)的折扣程度比“为他人得益”框架下(含NG-G、L-G)低;(3)任务框架与社会距离的交互作用影响社会折扣程度。随着社会距离增加, NG-G与NG-NL框架下折扣程度的差异逐渐变小, L-G与L-NL框架下折扣程度的差异也逐渐变小;(4)社会距离与利他人格的交互作用显著,高低利他人格者的社会折扣程度只在社会距离较远时存在显著差异。上述结果表明,个体不仅存在自我损失规避倾向,也存在不同程度的他人损失规避倾向。     

老化刻板印象研究现状及展望

老化刻板印象是人们对老年人所持有的观念与预期,它能显著影响老化刻板印象持有者的生理功能、认知功能和行为结果。现有研究主要集中在老化刻板印象的机制、影响因素和中介变量方面。研究发现,老化刻板印象是通过内化形成的,刻板印象威胁理论和自我刻板化是解释老化刻板印象的两种作用机制。认知加工过程中的抑制能力、情境和文化差异是影响老化刻板印象的主要因素,而老化自我知觉和刻板期望则是老化刻板印象影响效果变量的中介因素。未来研究除了要继续探讨意识水平、情境因素、个体特征对老化刻板印象的影响以及老化刻板印象对不同年龄群体影响的特点以外,还应关注中介和干预研究,并进一步加强跨文化研究。     

Repetition-lag training to improve recollection memory in older people with amnestic mild cognitive impairment. A randomized controlled trial

The results of a randomized controlled trial of repetition-lag training in older adults with amnestic mild cognitive impairment (aMCI) are reported. A modified repetition-lag training procedure with extended encoding time and strategy choice was used. The training required discriminating studied words from non-studied lures that were repeated at varying intervals during the test phase. Participants were assessed pre/post using untrained measures of cognition and self-report questionnaires. Primary outcome measures were recall of unrelated word pairs both immediately following presentation and following a delay. Secondary outcomes were a measure of attention, cognitive flexibility, and visual working memory. Participants were also asked to report on the frequency of cognitive failures and mood before and after training. Participants (N = 31) were randomized into either the treatment or a no-contact control group and attended the clinic twice per week over a four week period. Twenty-four participants completed the study (twelve in each group). Results indicated that the training group improved at recalling unrelated word pairs after a delay. There were no significant effects of training on other outcomes, self-reported cognitive failures or mood. The results are discussed along with suggestions for future research.     

血尿酸水平与脑梗死及其各指标的相关性分析

研究血尿酸(UA)与脑梗死发病与预后的相关性.本试验选择2008年5月至2009年3月中国医科大学附属一院神经内科就诊的脑梗死患者为病例组,同期中国医科大学附属一院门诊体检者70例为对照组,均进行血尿酸(SUA)、总胆固醇(TC)、甘油三酯(TG)、低密度脂蛋白(LDL-C)、高密度脂蛋白(HDL-C)、空腹血糖(FBG)、纤维蛋白原(Fg)及C反应蛋白(hs-CRP)及血压的测定.比较病例组与对照组的相关指标的变化,并比较高尿酸与非高尿酸组的梗死例数与严重程度、生化指标等的变化.脑梗死组SUA水平明显高于对照组(P＜0.05);HUA组的患病率也显著高于非HUA组(P＜0.05);大梗死灶组UA值高于小梗死灶组(P＜0.05),中梗死灶组UA值高于小梗死灶组(P＜0.05).重度损伤组UA值大于轻度组(P＜0.05);中度损伤组UA值大于轻度组(P＜0.05).HUA组的SBP、DBP、TC、TG、LDL-C、FBG及hs-CRP各值高于非HUA组,HDL-CD低于非HUA,差异有统计学意义(P＜0.05).     

医学生妇产科临床见习渗透伦理学教学的意义

现代医生应是专业技能与人文素养兼备的形象,医学伦理学素质是医学生理应具备的品格.实践证明,医学伦理学临床见习是培养医学生医学伦理学素质的必要环节.医学伦理学的临床见习,能固化医学生的知识体系,有利于医学生医学伦理学素质的养成,帮助提高医学生分析和解决医学临床实践中面临的伦理困境.而妇产科室由于其特殊性,在临床见习中渗透伦理学教学的意义尤为重大,通过妇产科医学伦理学临床见习的设计与实施,科学合理地选择见习的内容,寻找最佳的见习方式和方法,完善见习的评定体系和考核形式,医学伦理学的教学效果立竿见影.     

化疗后不同时间有氧运动对乳腺癌癌因性疲乏的影响

探讨化疗后不同时间运动干预对乳腺癌癌因性疲乏的影响.将60例行根治术并完成第二周期化疗,接受第三周期化疗的乳腺癌患者随机分为四组,每组15人,对照组行医院常规护理;试验组分为A、B、C三组,除常规护理外按护士制定的有氧运动干预方式分别于化疗后第1天、化疗后第3天,化疗结束后规律锻炼.使用修订的Piper疲乏量表(RPFS)对四组患者在化疗前2天、化疗后第1天(运动干预之前)和化疗后21天进行评估.结果化疗前2天四组RPFS得分均无差异(P＞0.05),化疗后21天对照组RPFS得分均高于试验组,试验C组RPFS得分高于试验A、B组.因此,化疗后及早活动能有效缓解患者的癌因性疲乏.     

The Relationship‐specific Interpretation Bias Mediates the Link between Neuroticism and Satisfaction in Couples

Neuroticism has repeatedly been shown to be a predictor of relationship dissatisfaction in couples. The aim of the current research was to uncover the underlying cognitive processes of this robust effect. We focused on anxiety as one aspect of neuroticism that is associated with different kinds of cognitive biases. On the basis of the assumption that biased information processing will also affect specific interpersonal contexts such as romantic relationships, it was expected that the tendency to interpret ambiguous partner and relationship scenarios in a rather negative way would work as a potential mediator. In Study 1, parallel forms of a new measure to capture the relationship‐specific interpretation bias (RIB) were developed (N = 182). In Study 2, the proposed meditational role of the RIB was investigated in a dyadic sample of 210 couples. Dyadic analysis using the Actor–Partner Interdependence Mediation Model showed mediation of the interpretation bias even when the general interpretation bias and attachment styles were controlled. Results support the assumption that biased relationship‐specific interpretations are one important mechanism for how neuroticism exerts its negative influence on relationship satisfaction. We conclude that personality‐congruent cognitive processing may not only have individual consequences but also affect overall couple functioning. Copyright © 2013 John Wiley & Sons, Ltd.     

八字易象对性二元论的思想贡献及其意义——兼论术数对中国古代哲学的影响

儒家性二元论的产生与流行与当时所流行的八字术(八字易象)密切相关。八字易象是一种以人出生时间的天干地支所形成的阴阳五行之象研究人生及天人关系的术数。其思想观点和术数活动,影响了宋代理学性二元论。八字易象在性、理、气等问题上也具有一定的思想深度。中国古代术数及其思想对中国哲学史的影响与意义,是一个长期被忽略的问题。研究术数的思想资源,有助于我们批判迷信思想,了解中国思想史上阴阳五行思想多方面的内容,也有助于我们吸收传统思想,建立新时代的中国哲学。     

压力使人短视?来自跨期决策的证据

跨期决策是指个体对不同时间点上的收益或损失进行的权衡和选择。本研究探讨了日常慢性压力知觉和实验室急性压力操作对跨期决策的影响。研究一通过问卷调查发现高压力感与跨期决策中的短期偏好有关;研究二采用社会压力测试范式(TSST)在实验室进行压力操作,同样发现压力组被试比控制组更偏好"小而近"的选项。研究认为,压力使人在跨期决策中倾向于短视选择,可能与双系统激活模式和自我控制资源损耗有关。
