天使之吻还是魔鬼之恋--对"医学整形美容热"的哲学困惑和价值存疑

当代医学罔顾主体深层危机和机制缺损,正危险地迎合着"造美风潮",从而使整形美容医学不断走向极端化,很值得理论医学界及时反思.医学应当履行"解社会之痛"之使命,而不能满足于"搔社会之瘁"."人工美女"的横空出世,是商业化炒作和恶俗化的医疗技术相结合的"尤物",是对医学核心价值体系的恣肆扭曲和嘲弄,更会引起哲学上的困惑和招致重大医学问题.     

斯腾伯格思维风格理论述评

通过对传统学校教育弊端的分析,引入了斯腾伯格的“思维风格”理论,即三个层面上13种不同风格的心理自我管理理论,同时阐述了该理论与智力的关系,以及对学校教学改革的影响。我们通过保存多种风格形式,提升学校教学和评估环爷,将多种教育方式匹配于不同的风格类型,并积极教授之来实现对传统教学体制的改革。     

择偶复制:一种适应性的性选择策略

择偶复制是一种择偶策略.在阐明择偶复制概念及研究范式的基础上,以阐述择偶复制影响因素的形式,介绍了择偶复制的研究成果、发展脉络.例如,性别影响择偶复制:相对于男性,女性被试更容易产生择偶复制;身体吸引力、性策略、年龄及性经验等影响择偶复制.在此基础上,进一步指出择偶复制的一般化是导致择偶偏好群体内一致性和群体间差异性的原因之一.最后,点明择偶复制的性质:基于社会学习的、适应性的性选择策略.     

影响ICU护士落实“知情同意原则”原因及对策

重症监护（intensive care unit,ICU）医生越来越重视在诊疗活动过程中的知情同意权,各种重要诊疗活动都与患者和家属沟通,并取得口头或文字上的同意,但部分护理人员对知情同意原则不重视,在环节中落实不力,从而易引发护患纠纷。而保证患者获得知情同意权是护理人员必须落实的义务,护士的告知是维护患者知情同意权和...     

竞争情境下社会比较认知偏差实验研究

本文以在校大学生为被试,考察社会比较的一个重要领域—学业竞争中的比较偏差。通过操纵竞争双方的实力(强VS.弱)以及竞争对手的信息清晰度(清晰VS.模糊)来考察不同的任务类型与信息清晰度对竞争中认知偏差的影响,以及探讨认知偏差对决策者决策意图的影响。结果发现,在社会比较中,面对不同类型的问题,会出现不同的认知偏差;竞争双方信息清晰时优于常人效应会减弱;认知偏差会影响个体的决策意图和决策行为。     

Using SAS PROC TCALIS for multigroup structural equation modelling with mean structures

Multigroup structural equation modelling (SEM) is a technique frequently used to evaluate measurement invariance in social and behavioural science research. Before version 9.2, SAS was incapable of handling multigroup SEM. However, this limitation is resolved in PROC TCALIS in SAS 9.2. For the purpose of illustration, this paper provides a step-by-step guide to programming the tests of measurement invariance and partial invariance using PROC TCALIS for multigroup SEM with mean structures. Fit indices and parameter estimates are validated, thus providing an alternative tool for researchers conducting both applied and simulated studies. Other new features (e.g., different types of modelling languages and estimation methods) and limitations (e.g., ordered-categorical SEM and multilevel SEM) of the TCALIS procedure are also briefly discussed.     

Integrating physical constraints in statistical inference by 11-month-old infants

Much research on cognitive development focuses either on early-emerging domain-specific knowledge or domain-general learning mechanisms. However, little research examines how these sources of knowledge interact. Previous research suggests that young infants can make inferences from samples to populations (Xu & Garcia, 2008) and 11- to 12.5-month-old infants can integrate psychological and physical knowledge in probabilistic reasoning (Teglas, Girotto, Gonzalez, & Bonatti, 2007; Xu & Denison, 2009). Here, we ask whether infants can integrate a physical constraint of immobility into a statistical inference mechanism. Results from three experiments suggest that, first, infants were able to use domain-specific knowledge to override statistical information, reasoning that sometimes a physical constraint is more informative than probabilistic information. Second, we provide the first evidence that infants are capable of applying domain-specific knowledge in probabilistic reasoning by using a physical constraint to exclude one set of objects while computing probabilities over the remaining sets.     

Induction, overhypothesis, and the origin of abstract knowledge. Evidence from 9-month-old infants

Human cognition relies on the ability to extract generalizable knowledge from limited evidence. One type of inductive learning, overhypothesis formation, allows learners to make inferences that take them beyond the limits of direct experience, leading to the creation of abstract knowledge. The developmental roots of this ability have yet to be investigated. We report three experiments examining whether 9-month-old infants are capable of forming overhypotheses. Our results show that when given evidence about a few objects in some category, infants formed a second-order generalization about categories in general. These findings provide evidence that infants possess a powerful mechanism for inductive learning-a mechanism that may be applied to many domains and that can account for the development of many inductive biases later on.
