记忆重构和信心评估:商标属性与使用经验的影响

记忆是重现,还是重构?已有理论存在争论。本研究以商标信息为实验材料,应用任务分离范式、元记忆检测范式等方法,探讨了商标属性和用户使用经验对记忆重构的影响。结果发现:(1)商标信息的正确回忆频数及成绩显著低于错误回忆的频数和成绩。(2)简单商标的记忆成绩高于复杂商标的记忆成绩;同时,忠实用户对商标信息的记忆成绩显著高于非忠实用户;(3)在回忆任务之前,人们对商标信息的回忆及其信心评估存在分离;但在回忆任务后二者的变化趋于一致。这表明,复杂程度对商标信息的记忆重构存在显著影响,而且存在用户类型差异;商标信息的记忆重构过程中元认知判断及信心评估会发生变化。

Stigma building blocks: how instruction and experience teach children about rejection by outgroups

Gaining an understanding of intergroup relations and outgroup rejection is an important childhood development. Children learn about rejection by outgroups via their own experiences and external instruction. A comparison of the impact of experience and instruction on first-, third-, and fifth-grade children's evaluations of rejection by outgroups in a minimal-groups paradigm suggests that the relative impact of experience and instruction differs as children age. In Study 1, younger children were more influenced by instruction, and older children were more influenced by what they experienced for themselves. In Study 2, younger children were more influenced by instruction, even when that instruction conflicted with what they experienced; older children were more influenced by their own experiences, even when those experiences contradicted what they were told to expect. These findings suggest that children begin learning about outgroup rejection through instruction but start to rely more on their own experiences as they age.     

童年晚期同伴关系不利与儿童的攻击行为:自我概念与同伴信念的中介作用

采用整群抽样法选取1806名小学儿童(平均年龄11.27±0.36岁)为被试,考察同伴拒绝、侵害两种同伴关系不利与儿童攻击行为间的关系、以及儿童的自我概念与同伴信念在其中的中介作用.结果发现,(1)同伴拒绝、侵害与儿童的身体攻击、关系攻击显著正相关,与儿童的自我概念、同伴信念显著负相关,自我概念、同伴信念与两类攻击显著相关.(2)同伴拒绝、关系侵害对身体攻击和关系攻击具有正向预测作用;身体侵害仅对身体攻击具有正向预测作用,对关系攻击无显著影响.(3)儿童的身体自我概念、社交自我概念及同伴信念在同伴拒绝、同伴侵害与攻击的联系中具有中介作用.本研究结果表明,同伴拒绝对儿童的身体攻击、关系攻击主要表现为直接效应,不同类型的侵害经历与儿童攻击间的联系存在类型特定性.     

Personalized persuasion: tailoring persuasive appeals to recipients' personality traits

Persuasive messages are more effective when they are custom-tailored to reflect the interests and concerns of the intended audience. Much of the message-framing literature has focused on the advantages of using either gain or loss frames, depending on the motivational orientation of the target group. In the current study, we extended this research to examine whether a persuasive appeal's effectiveness can be increased by aligning the message framing with the recipient's personality profile. For a single product, we constructed five advertisements, each designed to target one of the five major trait domains of human personality. In a sample of 324 survey respondents, advertisements were evaluated more positively the more they cohered with participants' dispositional motives. These results suggest that adapting persuasive messages to the personality traits of the target audience can be an effective way of increasing the messages' impact, and highlight the potential value of personality-based communication strategies.     

不同透析类型对尿毒症患者超敏C-反应蛋白与甲状腺功能的影响

分析不同透析类型对尿毒症患者的超敏C-反应蛋白与甲状腺功能的变化,并探讨其临床意义.对我院肾脏内科2009年10月～2011年6月的尿毒症维持性透析患者进行回顾性分析,20例血液透析(HD)患者为HD治疗组,20例腹膜透析(PD)患者为PD治疗组,20例健康者为正常对照组,各组检测超敏C-反应蛋白(hsCRP)、血清游离T3(FT3)、血清游离甲状腺激素(FT4)、促甲状腺激素(TSH)的含量等指标,分析各组间hsCRP有无差异性,同时分析hsCRP与FT3、FT4、TSH之间有无相关性.与正常对照组相比,HD组和PD组FT3、FT4显著降低(P＜0.05),hsCRP显著升高(P＜0.05).FT3和FT4在HD组中和PD组中相比差异无显著统计学意义(P＞0.05).PD组中,TSH水平显著高于HD组与正常对照组(P＜0.05).HD组中,hsCRP与FT3存在着负相关,但在PD组中没有发现此相关性.血液透析患者炎症反应与低FT3综合征有关,腹膜透析患者无此关联性,hsCRP及甲状腺功能检测可能有助于判断尿毒症透析患者的病情及预后.     

放弃治疗的法律和伦理学思考

调查放弃治疗后死亡病案629例,主要病因为恶性肿瘤和脑血管病.目前在临床工作中,对疾病晚期和临终期的患者,放弃治疗已成为家属和患者本人重要的选择之一.医患双方应该尊重医学科学,理性对待放弃治疗,履行双方应尽的义务,维护双方合法权力,维护法律的尊严.医院应该加强管理,正确处理放弃治疗的相关问题,更好地服务于患者和社会.     

On Public Aid to Christian Schools in the United States: A Reformed Christian Perspective

This paper seeks to provide a conceptual framework for understanding the topic of public aid to Christian schools in a Reformed Christian perspective. To do so, I need to clarify a Reformed Christian approach in regard to this topic and then review the studies of the issue in legal and educational aspects in the light of the Reformed perspective. Through reviewing legal and educational discussions, I argue that Christian schools are necessary for people to exercise their religious freedom and make a society more moral and spiritual and thus deserve receiving public aid. Nevertheless, public aid to religious schools needs to be carried out in a careful, restricted way.     

Effects of Racial Discrimination,Childhood Trauma,and Trauma Symptoms on Juvenile Delinquency in African American Incarcerated Youth

To understand racial disproportionality in juvenile delinquency, we studied relationships between 2 possible contributors: effects of manifestations of a structural factor (racism) and psychological consequences of trauma. Informed by Carter’s (2007) theory of race-based trauma, we explored the role of experiences of racial discrimination, childhood trauma, and trauma symptoms in juvenile delinquency through self-reported experiences of incarcerated African American youth. We found that childhood trauma, trauma symptoms, and racial discrimination experiences all significantly contributed to juvenile delinquency, but participants who experienced greater racial discrimination had higher posttraumatic stress symptoms and elevated delinquency rates. Considering the well-documented effects of trauma symptoms on juvenile delinquency, race-based trauma experiences might help us understand one aspect of racial disproportionality in juvenile delinquency.
