两种水化疗法对预防对比剂肾病的效果研究

比较两种水化疗法对对比剂肾病(contrast-induced nephropathy,CIN)的预防效果.将150例患者随机分为氯化钠水化组(50例)、碳酸氢钠水化组(50例)和常规治疗组(50例),检测患者造影前3天内及造影后第3天、7天的血肌酐、尿素氮和尿β2微球蛋白.分析三组患者CIN的发病率.结果两水化组CIN的发病率均显著低于常规治疗组(P<0.05),两水化组闻CIN的发病率无明显差异(P>0.05).结果提示两种水化疗法对CIN的预防效果相仿.     

《管子》财富哲学思想初探

财富的本质与源泉是人的感性活动即力、劳身的结果,是人的本质力量的对象化产物。人是最宝贵的财富,财富还包括劳动产品如谷物、自然财富、货币财富。财富的分配和消费具有社会权力性,社会权力是人的感性活动异化的结果。财富具有道德性,财富和道德融为一体即实德。     

从归因视角探讨公共物品两难中惩罚系统对合作的影响

社会两难中惩罚系统对合作的影响是当前的一个研究热点。前人研究发现惩罚系统可以促进合作,但也有学者提出惩罚系统对合作动机具有破坏作用,存在不一致结论。且这些研究大多只关注金钱惩罚而忽略了社会惩罚。本文采用2(惩罚类型:金钱,社会)×2(惩罚频率:高,低)×2(阶段:有惩罚,无惩罚)混合设计,利用"惩罚撤除"实验范式,比较了社会高低频惩罚和金钱高低频惩罚对合作、归因以及预期的影响。并探讨了合作、归因、预期之间的相互关系,结果发现:(1)金钱和社会惩罚均可提高被试合作水平;(2)金钱高频惩罚减少了对合作行为的内归因,惩罚撤除后合作行为下降,而低频惩罚没有出现下降效应;(3)社会惩罚增加了对合作的内归因,高低频惩罚在移除之后均保持较高水平,且之前的惩罚频率越高,保持效果越好;(4)合作、预期与内归因正相关,外归因负相关,同时合作与预期正相关。     

From glamour-oriented idolatry to achievement-oriented idolatry: A framing experiment among adolescents in Hong Kong and Shenzhen

The present study examined the framing effect of two modes of idolatry among a sample of 1095 secondary school students in Hong Kong and Shenzhen. Two experimental conditions were set up: in the glamour frame condition, subjects were exposed to frames that enhanced perfection and mystification of idols' personal or ideological characteristics; in the achievement frame condition, subjects were exposed to frames that enhanced emulation and identification of idols' pro-social behaviours or desirable dispositional traits. The experiment selected a prominent pop music and movie star well known in Chinese societies, Andy Lau, as the target idol. Subjects showed a consistently and significantly greater desire to glorify, idealize, identify with, emulate, and attach to Andy Lau in the achievement frame condition than in the glamour frame condition. The finding suggests that an achievement frame can heighten young people's adoration of an idol by emphasizing the idol's achievement processes. This suggestion is favourable to the possibility of transforming an idol into a role model for young people to learn to pursue career success.     

Recruitment of the pre-motor area in human inductive reasoning: An fMRI study

Recent studies indicated that the pre-motor area may be recruited in human higher level cognitive functions, including inductive reasoning. In the present study, a typical task of inductive reasoning, function-finding, was explored using functional MRI. fMRI results showed the significant activation of bilateral pre-motor cortex (BA 6), and its left lateralization. Taking together the previous studies and the present experimental design, we concluded that the left pre-motor cortex in the present study may associate with implicit relation synthesis, while the right pre-motor cortex may reflect spatial information processing involved in arithmetic rules.     

RTbox: A device for highly accurate response time measurements

Although computer keyboards and mice are frequently used in measuring response times (RTs), the accuracy of these measurements is quite low. Specialized RT collection devices must be used to obtain more accurate measurements. However, all the existing devices have some shortcomings. We have developed and implemented a new, commercially available device, the RTbox, for highly accurate RT measurements. The RTbox has its own microprocessor and high-resolution clock. It can record the identities and timing of button events with high accuracy, unaffected by potential timing uncertainty or biases during data transmission and processing in the host computer. It stores button events until the host computer chooses to retrieve them. The asynchronous storage greatly simplifies the design of user programs. The RTbox can also receive and record external signals as triggers and can measure RTs with respect to external events. The internal clock of the RTbox can be synchronized with the computer clock, so the device can be used without external triggers. A simple USB connection is sufficient to integrate the RTbox with any standard computer and operating system.     

重复犯罪罪犯人格特征的分析及预防对策

采用《中国罪犯心理测试个性分测验》(COPA-P)I测量罪犯的人格特征,并对初犯和重复犯罪罪犯的人格特征进行比较。结果发现,在攻击性、报复性、犯罪思维模式这三个因子上,重复犯罪的罪犯明显高于初犯。并具体分析了其人格特点,针对重复犯罪罪犯人格的特殊性,提出了在改造过程中相应的措施。     

应聘情境下作假识别量表的开发

在应聘情境中, 被试容易对人格测验作假。应对作假的常用方法是采用社会称许性量表对作假直接测量, 再去校正和识别作假效应。但是采用社会称许性量表测量作假存在很多问题, 因而基于作假的特殊性质开发了《作假识别量表》。采用探索性因素分析证实了量表的单维性, 解释率为54.650%。概化理论检验表明测验信度较好, G系数为0.906, j系数为0.902。采用一个真实的应聘情境检验效度, 发现《作假识别量表》对作假更加敏感, 能够比较充分地测量作假。     

轻度阿尔茨海默症患者的前瞻记忆

轻度阿尔茨海默症往往伴随着不同程度的前瞻记忆衰退。已有研究以轻度阿尔茨海默症与前瞻记忆衰退的关联程度为主线, 对比了这一关联与“其他认知缺陷疾病-前瞻记忆衰退”、“轻度阿尔茨海默症-回溯记忆衰退”以及“轻度阿尔茨海默症-遗传表达”这三种关联的类似程度。此外, 也有研究涉及到了如何促进轻度阿尔茨海默症患者的前瞻记忆。将来的研究应引入病情程度、前瞻记忆任务类型等变量, 深入探讨轻度阿尔茨海默症与前瞻记忆衰退的关联, 并使用ERP、fMRI等神经生理技术确定轻度阿尔茨海默症患者前瞻记忆衰退的机制。     

基础认知与社会认知中内隐过程及其脑机制*

认知过程及其脑机制是心理学研究的重要内容。社会认知是人们在社会生活中对他人行为的意图及情感的认识,是人际互动的重要方面,具有深刻的理论和实践意义。本文全面深入地对社会认知和基础认知中自动加工过程进行了研究综述,对基础认知与社会认知的研究方式进行了比较。自动加工过程是社会认知和基础认知中都存在的重要过程,从脑机制研究角度,相关的电生理学指标(如N400等)都可以作为研究的指标来考察社会认知中的自动加工过程。本文从社会认知与基础认知的比较入手,介绍了各种领域的研究方法,特别是事件相关电位技术等认知神经科学研究方法。
