身体拥有感及其可塑性：基于内外感受研究的视角

身体自我表征中的身体拥有感(即我的身体属于我的感受)问题一直是自我意识研究的核心话题。大量的已有研究表明, 身体拥有感的体验涉及不同感官信号的整合, 当前大多数研究只重视视觉、触觉等外感受的作用, 一方面忽视了内感受的作用, 另一方面也缺乏对两类感受整合的关注。橡胶手错觉实验和身体障碍患者身上所表现出的外感受和内感受对身体拥有感的影响支持了身体拥有感的可塑性假设, 自由能量原理认为身体拥有感形成的基础是大脑不断评估更新可能性表征来维持稳定。未来的研究需要从改善内感受的测量和刺激呈现方法, 探索影响内感受的高阶认知因素以及关注某些神经症患者的内感受等方面寻求突破。     

工作反刍及其“双刃剑”效应

工作反刍指在没有要求其出现的情境下, 有意识的、重复发生的工作方面的相关想法, 分为工作相关情感反刍与工作相关问题解决沉思两个维度。工作反刍对个体健康、工作及幸福感的影响有“双刃剑”效应。持续性认知理论、压力认知激活模型与认知资源视角理论, 可以解释该效应的内在机制。未来研究应分析影响双刃剑效应的边界条件, 寻求减少消极效应、增加积极效应的途径, 拓展其双刃剑效应心理机制的分析视角和该效应的作用层面。     

身体表征的分离:二分解释模型及其证据

身体表征是一种内部结构,它具有追踪身体状态并对其进行编码的功能。这种结构可以对身体进行错误的表征,并可以从身体中分离出来。来自海豹肢症与躯体失认症等方面的病例,证实部分身体畸形与脑损伤患者的身体表征存在分离;来自橡胶手错觉与全身错觉的实验证据,验证了健康个体身体表征分离的事实。基于上述证据,以身体图式和身体意象为二分维度的模型解释了身体表征的分离。未来的研究可以从神经心理学实验和虚拟现实技术着手,对身体表征的分离进行深入探究。     

论霍耐特对卢卡奇物化理论的批判性重建

从卢卡奇对物化概念的分析开始,关于物化理论的研究在现代哲学界就从未停止。霍耐特立足于社会批判与社会发展之间落差的思考,以其独特的理论视角,将物化生发的判准向内翻转,以“原初承认”作为理论支点,拓展了卢卡奇的物化批判视域。霍耐特试图在社会生活层面及生存结构中寻求社会病态的可能成因,提供一种在当代社会推进物化批判的独特路径,在发展社会批判理论以及建立社会批判范畴新形式上作出独特贡献。     

医疗卫生产业组织研究与卫生政策

产业组织理论是经济学的重要分支之一,卫生经济的发展需要借鉴它的手段和方法,需要研究医疗卫生产业组织的相关问题.农村新型合作医疗的建立和发展,城市医疗卫生服务体系的再造,都离不开医疗卫生产业组织研究.市场,特别是非完全竞争的医疗服务市场,它的市场结构、市场主体行为和市场绩效之间内在的本质联系,是卫生政策能够发生应有效力的作用点.     

On the flexibility and the fallibility of associative memory

We report the results of four experiments in which we explored the flexibility and fallibility of associative recognition memory. In each experiment, pairs were studied one or more times, and the task was to discriminate intact from rearranged pairs. The critical findings are that the pattern of false alarm rates was dependent on the nature of the recognition procedure (e.g., ratings vs. yes-no) and the situation in which the task was performed. The specific pattern of findings suggest that subjects adopt different recognition strategies in order to achieve a desired level of performance in the most efficient manner possible by varying the degree to which they base their decisions on familiarity versus recollected information. Implications for theories of recognition memory are discussed.

该文对青少年学生的人际信任度与家庭因素的关系进行研究,结果表明:1)青少年学生人际信任度的性别差异不显著;2)青少年学生人际信任度的年级差异显著:大学生的人际信任水平最低,初中生的最高,职业中专学生的与大学生的相近;3)青少年学生的人际信任度与其家庭环境的相关不显著。     

Counterfactual comparison modulates fairness consideration in the mini‐ultimatum game: An event‐related potentials study

Existing literature on the mini‐ultimatum game indicates that counterfactual comparison between chosen and unchosen alternatives is of great importance for individual's fairness consideration. However, it is still unclear how counterfactual comparison influences the electrophysiological responses to unfair chosen offers. In conjunction with event‐related potentials’ (ERPs) technique, the current study aimed to explore the issue by employing a modified version of the mini‐ultimatum game where a fixed set of two alternatives (unfair offer vs. fair alternative, unfair vs. hyperfair alternative, unfair offer vs. hyperunfair alternative) was presented before the chosen offer. The behavioral results showed that participants were more likely to accept unfair chosen offers when the unchosen alternative was hyperunfair than when the unchosen alternative was fair or hyperfair. The ERPs results showed that the feedback‐related negativity (FRN) elicited by unfair chosen offers was insensitive to the type of unchosen alternative when correcting for possible overlap with other components. In contrast, unfair chosen offers elicited larger P300 amplitudes when the unchosen alternative was hyperunfair than when the unchosen alternative was fair or hyperfair. These findings suggest that counterfactual comparison may take effect at later stages of fairness consideration as reflected by the P300.     

The Training Effect of Working Memory Based on Central Executive System Intervention in Older Adults: A Randomized Controlled Study

This article aims to investigate the training effect of working memory in older adults. A total of 43 older adults ranging in age from 75 to 95 were recruited to participate in the study. A battery of tests regarding central executive function, working memory, and primary mental ability were administered in the pretest phase. A total of 22 of the older participants were randomly selected as the intervention group. Thirteen days after the pretest, the same tests were administered to all of the participants. The results showed that (1) the differences in the pretest and posttest gains in the task-switching tests were not significant between the intervention group and the control group; (2) the performance of the intervention group on the operation working memory span test and the graphical reasoning test showed a significant improvement after the intervention compared with the control group who did not receive the intervention. We can conclude that the working memory of old adults may be improved by an intervention targeting the central executive system. However, this possibility needs further investigation.     

中小学教师PTSD和PTG的影响因素研究：灾难前-中-后的视角

采用事件影响量表、创伤后成长问卷、社会支持问卷、应对方式问卷等对汶川地震1年后极重灾区的106名中小学教师进行调查,考察前灾难因子、灾难当下因子和后灾难因子等对教师创伤后应激障碍（PTSD）和创伤后成长（PTG）的影响。结果发现：（1）灾后中小学教师的PTSD处于中低水平、PTG处于中上水平,其中女教师的PTSD和PTG水平高于男教师,班主任教师PTSD水平高于非班主任教师,有过被困经历的教师PTSD水平高于没有被困经历的教师,有亲朋或学生受伤的教师其PTSD和PTG水平均高于无亲朋或学生受伤的教师;（2）社会支持对PTSD没有显著的预测作用,社会支持中的信息支持可以促进PTG,而情感支持和实质性支持对PTG没有显著的影响;（3）逃避的应对方式能显著地正向预测PTSD,问题解决的应对方式能显著正向地预测PTG,而寻求帮助的应对方式对PTSD和PTG都不具有显著的影响。
