大学生自我复杂性与主观幸福感的关系

对188名大学生采用生活满意度量表和情感量表测量主观幸福感,运用与Linville相近的方式测量自我复杂性,并探讨两者的关系。研究发现:(1)积极自我复杂性与消极自我复杂性相互独立。(2)积极自我复杂性和消极自我复杂性与主观幸福感有着不同的关系。(3)自我复杂性测量时积极词汇与消极词汇的比例以及幸福感测量工具的不同都可能使两者关系出现不同结果。     

儿童假装游戏中假想角色现象初探

通过对145名4~5岁儿童进行结构式访谈,调查幼儿假装游戏中假想角色现象的概况,包括假想同伴和角色扮演现象。结果如下:42.7%的儿童有假想同伴,绝大多数是玩具形式,女孩更多有假想同伴;男孩倾向于选择动物类型的假想同伴,而女孩倾向于人物类型;假想同伴绝大多为同性别并且比自己年龄小。44.8%的儿童有角色扮演活动,其中男孩倾向于装扮动画中的英雄人物,女孩倾向于装扮现实人物。     

大学生优秀辩手与非辩手的非形式推理能力比较

为考察大学生优秀辩手与非辩手非形式推理能力的差异,运用"提示访谈法"对大学生中的优秀辩手与非辩手的普通大学生进行了比较研究。结果表明:大多数优秀辩手达到间接反驳推理水平,而多数非辩手处在直接反驳推理水平。优秀辩手不论在功能性和条件性理由的数量上,还是在理由领域广度上都显著优于普通大学生。在反驳式推理过程中,优秀辩手的间接反驳次数显著多于非辩手。研究表明大学生优秀辩手的非形式推理能力显著优于非辩手。     

论我国社会养老保险的整合

由于复杂的历史原因,我国各种养老保险未能作为一个整体进行系统设计,从而形成养老保险模式体制分割、城乡分割、地区分割的局面,导致公务员、事业单位职工、企业职工养老金差距悬殊以及农民工养老保险关系无法转移接续.应遵循促进公平正义、适应发展趋势、实现多方共赢的理念和原则对养老保险体系进行整合.具体做法是:(1)四大养老保险均应实行"统账结合"的基本制度,实现体制并轨;(2)"基础养老金"全国统筹,实现各种养老保险的可转移接续.(3)国家调节"基础养老金",逐步缩小养老金差距.

Feeling of knowing for names in response to faces

Participants were asked to recall the names when shown photographs of faces in both a semantic task (Experiment 1) and an episodic task (Experiments 2 and 3). When recall failed, feeling of knowing (FOK) ratings were solicited. In addition, participants reported on the strategies that they used to make their ratings, whether they could recall other pieces of information (the target-accessibility strategy, e.g., Koriat, A. (1993). How do we know that? The accessibility model of the feeling of knowing. Psychological Review, 100, 609–639) or whether the faces simply looked familiar (the cue-familiarity strategy, e.g., Schwartz, B. L., & Metcalfe, J. (1992). Cue familiarity but not target accessibility enhances feeling of knowing ratings. Journal of Experimental Psychology: Learning, Memory, and Cognition, 18, 1074–1083). In all experiments, FOK ratings were fairly accurate in that participants were successful in predicting their performance on a subsequent recognition test. More importantly, participants reported using the cue-familiarity strategy more often, although they gave higher FOK ratings when they reported using the target-accessibility strategy. The FOK ratings that were given using the two strategies were equally accurate.     

Mereological vagueness and existential vagueness

It is often assumed that indeterminacy in mereological relations—in particular, indeterminacy in which collections of objects have fusions—leads immediately to indeterminacy in what objects there are in the world. This assumption is generally taken as a reason for rejecting mereological vagueness. The purpose of this paper is to examine the link between mereological vagueness and existential vagueness. I hope to show that the connection between the two forms of vagueness is not nearly so clear-cut as has been supposed.     

Individual attitudes and perceived social norms: Reports on HIV/AIDS‐related stigma among service providers in China

This study examined HIV/AIDS‐related stigma among Chinese service providers by comparing their personal attitudes toward people living with HIV/AIDS with their perception of social norms related to people living with HIV/AIDS. We randomly selected three provincial hospitals, four city/prefecture hospitals, 10 county hospitals, 18 township health clinics, and 54 village clinics from Yunnan, China. Doctors and nurses were randomly sampled proportionally to the doctor–nurse ratio of each hospital or clinic. Lab technicians were over‐sampled in order to include an adequate representation in the analysis. A total of 1,101 service providers participated in a voluntary, anonymous survey where demographic characteristics, individual attitude and perceived social norms toward people living with HIV/AIDS, discrimination intent at work, general prejudicial attitude and knowledge on HIV/AIDS were measured. A majority of the sample demonstrated a similarity between their personal views and what they thought most people in society believe. Multiple logistic regressions revealed that participants who were younger or reported personal contact with people living with HIV/AIDS were significantly more likely to report personal attitudes toward the population that were more liberal than their perceived social norms. Holding a more liberal personal attitude toward people living with HIV/AIDS than perceived social norms was significantly and negatively related to the level of discrimination intent at work, perceived discrimination at interpersonal level and the level of general prejudicial attitude toward people living with HIV/AIDS. Results underscored the importance of understanding social norms and personal attitudes in studying HIV‐related stigma and called for the incorporation of existing human capital into future HIV stigma reduction programs.     

A Structural Analysis of the Phlogiston Case

The incommensurability thesis, as introduced by T.S. Kuhn and P.K. Feyerabend, states that incommensurable theories are conceptually incompatible theories which share a common domain of application. Such claim has often been regarded as incoherent, since it has been understood that the determination of a common domain of application at least requires a certain degree of conceptual compatibility between the theories. The purpose of this work is to contribute to the defense of the notion of local or gradual incommensurability, as proposed by late Kuhn. The application of this notion would allow to render the incommensurability thesis coherent. To support this view, a typical example of incommensurability will be formally analyzed by applying the structuralist metatheory developed, among others by W. Balzer, C.U. Moulines and J.D. Sneed. The structural reconstruction of the relation between the phlogiston theory and the oxygen theory offered here will reveal that they are locally incommensurable, and will even make possible to determine the ontological reduction relation that they also exemplify.

Behavioral and neural correlates of memory selection and interference resolution during a digit working memory task

Neuroimaging studies have shown the involvement of prefrontal and posterior parietal cortexes in regulating information processing. We conducted behavioral and fMRI experiments to investigate the relationship between memory selection and proactive interference (PI), using a delayed recognition task with a selection cue presented during the delay indicating which two of the four studied digits were relevant to the present test. PI was indexed by the response time differences between rejecting probes matching and not matching the no longer relevant digits. By varying the delay intervals, we found that the effect of PI did not diminish, even for cases in which the postcue interval was extended to 9 sec, but was stronger when the precue interval was lengthened to 5 sec. By examining the correlation between PI index and neural correlates of memory selection, we found that stronger PI is predicted by lower selection-related activity in the left inferior parietal lobe, the precuneus, and the dorsal middle frontal gyrus. Our results suggest that activity in the prefrontal-parietal network may contribute to one’s ability to focus on the task-relevant information and may proactively reduce PI in working memory.
