云南少数民族女性与宗教研究述评

宗教作为一种社会意识形态,隐含着人类历史的文化基因.男女两性共同创造了历史,也创造了文化.近年来随着女性主义视角下社会性别研究的兴起,学术界对宗教的研究也开拓了新的理论视角与学术旨趣,如女性与宗教这一新动向的出现.云南民族众多,由于其地域文化的多样性和历史发展的不均衡性,其宗教类型齐全,信仰内涵丰富.在此背景下,本文拟对近些年来云南少数民族女性与宗教的相关研究情况,分别作一宗教人类学理论视角下的概述.     

Causation in Branching Time (I): Transitions,Events and Causes

We propose a theory of events and causes against the background of branching time. Notions discussed include possibility based on reality, transitions, events, determinacy, contingency, causes and effects. The main idea in defining causal relations is to introduce a certain preconditioning circumstance under which one event follows another. We also briefly compare this theory with some other theories.     

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。     

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.     

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.     

A study of the greater male variability hypothesis in creative thinking in Mainland China: Male superiority exists

This study tested the greater male variability hypothesis in creative thinking with a Chinese student sample in Mainland China. The Test for Creative Thinking-Drawing Production (TCT-DP) was administered to 627 Chinese adolescent boys (n = 332) and girls (n = 295). Results using the boy/girl variance ratio (VR) generally supported the hypothesis that boys have greater variability than girls in creativity test performance. However, results using the boy/girl ratios from different regions of the creativity score distribution revealed a pattern of male superiority. While boys significantly outnumbered girls in the higher extremes, girls tended to outnumber boys in the central region and the lower extremes. Results from an analysis of the means lent further support to the findings of male superiority. Plausible explanations for greater male variability and male superiority in Mainland China are proposed. The theoretical and practical implications of the findings are discussed.     

上下意象图式向抽象概念映射的心理现实性研究

通过考察上下意象图式隐喻的映射机制和形成机制,验证其向抽象概念的映射具有心理现实性.实验一中,学龄期儿童阅读与图式一致材料反应时,较阅读与图式不一致材料反应时短,说明上下意象图式存在于概念水平,并在即时阅读中被激活.实验二中,学龄前幼儿表现出物品摆放的上下方位偏好差异,表明幼儿在概念形成过程中,抽象概念与空间上下方位存在体验性联结.研究证明:部分抽象概念表征具有上下方位线索,人们借助上下意象图式建构抽象概念.     

视觉恐惧加工的神经通路

对危险信号的快速警觉具有生物学意义,研究发现视觉恐惧信号可以经过两条不同的通路传达杏仁核:一条直接的皮层下通路,另一条是间接的视觉皮层通路.最近三年(2004-2006)一批脑成像和电生理研究对此进行了深入探讨.本文以此为基础对两条通路的主要神经结构,神经传递的先后过程以及它们间的关系进行了详细的综述.     

儿童在错误信念任务上的知识偏差

采用3种任务考查儿童在错误信念（FB）推理中是否存在知识偏差。被试为60名3—5岁幼儿,结果表明,对于3岁及4岁儿童来说,FB任务是存在知识偏差的。知识偏差的大小与年龄呈负相关关系,3岁与4岁、4岁与5岁儿童的知识偏差的大小均有显著差异。     

Influence analysis for the factor analysis model with ranking data

Influence analysis is an important component of data analysis, and the local influence approach has been widely applied to many statistical models to identify influential observations and assess minor model perturbations since the pioneering work of Cook (1986) . The approach is often adopted to develop influence analysis procedures for factor analysis models with ranking data. However, as this well‐known approach is based on the observed data likelihood, which involves multidimensional integrals, directly applying it to develop influence analysis procedures for the factor analysis models with ranking data is difficult. To address this difficulty, a Monte Carlo expectation and maximization algorithm (MCEM) is used to obtain the maximum‐likelihood estimate of the model parameters, and measures for influence analysis on the basis of the conditional expectation of the complete data log likelihood at the E‐step of the MCEM algorithm are then obtained. Very little additional computation is needed to compute the influence measures, because it is possible to make use of the by‐products of the estimation procedure. Influence measures that are based on several typical perturbation schemes are discussed in detail, and the proposed method is illustrated with two real examples and an artificial example.
