自我同一性与相关概念的辨析

自我同一性是一个多层次、多维度的心理学概念．这一概念自提出后就面临着概念澄清的问题．尤其是与相关概念的边界划分问题。因此．要把握自我同一性的概念就需要对与自我同一性相关联的概念进行辨析。这主要涉及到(1)自我与同一性;(2)自我同一性与自我概念;(3)自我同一性与个人同一性、角色同一性和社会同一性。     

Imageability and semantic association in the representation and processing of event verbs

This study examined the relative salience of imageability (the degree to which a word evokes mental imagery) versus semantic association (the density of semantic network in which a word is embedded) in the representation and processing of four types of event verbs: sensory, cognitive, speech, and motor verbs. ERP responses were recorded, while 34 university students performed on a lexical decision task. Analysis focused primarily on amplitude differences across verb conditions within the N400 time window where activities are considered representing meaning activation. Variation in N400 amplitude across four types of verbs was found significantly associated with the level of imageability, but not the level of semantic association. The findings suggest imageability as a more salient factor relative to semantic association in the processing of these verbs. The role of semantic association and the representation of speech verbs are also discussed.     

19世纪英国的济贫院制度初探

从17世纪开始,济贫院在英国逐步发展起来;1834年后,院内救济成为新济贫法体系的核心。济贫法委员会希望通过济贫院的威慑作用,促使贫民自力更生,减少济贫开支。济贫院遵循“劣等处置”和“济贫院检验”两个原则,院内的生活比较悲惨,被大众冠以穷人的“巴士底狱”,到19世纪70年代后才逐步得到改善。济贫院制度在英国社会保障制度和福利国家形成过程中起到不可忽视的作用。     

民族国家的三大矛盾——来自吉登斯的启示

民族国家思想是吉登斯现代性思想体系的重要组成部分,代表了他对现代政治发展所作的反思。他从民主与监控、主权与暴力、民族与国家等三个角度出发,深入剖析了现代民族国家的发展动力和内在张力,深刻揭示了现代政治发展的矛盾性特征。     

高低行为激活系统个体在赌博任务下的决策模式

为考察不同行为激活系统/行为抑制系统下的个体在Iowa赌博任务反应模式下的决策行为,本研究采用人格问卷与行为实验相结合的方式,探讨了人格、冲动和行为决策间的关系。结果发现:(1)行为激活系统三个维度与行为决策存在显著负相关,行为激活系统低分组的IGT得分较高,行为激活系统高分组的IGT得分较低,而冲动特征与IGT得分相关不显著;(2)行为激活系统高、低分者在IGT任务上差异显著,且行为激活系统高分组者在收益-风险并存情境中表现出"即时收益优先"的决策模式。结果提示,在收益-风险并存情境中,高行为激活的人格特征者倾向风险决策模式。     

Unconsciously learning task-irrelevant perceptual sequences

We demonstrated unconscious learning of task-irrelevant perceptual regularities in a Serial Reaction Time (SRT) task in both visual and auditory domains. Participants were required to respond to different letters (‘F’ or ‘J’, experiment 1) or syllables (‘can’ or ‘you’, experiment 2) which occurred in random order. Unbeknownst to participants, the color (red, green, blue or yellow) of the two letters or the tone (1–4) of the syllables varied according to certain rules. Reaction times indicated that people indeed learnt both the color and tonal regularities indicating that task-irrelevant sequence structure can be learned perceptually. In a subsequent prediction test of knowledge of the color or tonal cues using subjective measures, we showed that people could acquire task irrelevant knowledge unconsciously.     

The nature of the memory buffer in implicit learning: Learning Chinese tonal symmetries

Previous research has established that people can implicitly learn chunks, which (in terms of formal language theory) do not require a memory buffer to process. The present study explores the implicit learning of nonlocal dependencies generated by higher than finite-state grammars, specifically, Chinese tonal retrogrades (i.e. centre embeddings generated from a context-free grammar) and inversions (i.e. cross-serial dependencies generated from a mildly context-sensitive grammar), which do require buffers (for example, last in-first out and first in-first out, respectively). People were asked to listen to and memorize artificial poetry instantiating one of the two grammars; after this training phase, people were informed of the existence of rules and asked to classify new poems, while providing attributions of the basis of their judgments. People acquired unconscious structural knowledge of both tonal retrogrades and inversions. Moreover, inversions were implicitly learnt more easily than retrogrades constraining the nature of the memory buffer in computational models of implicit learning.     

蒙古统治西域时宗教政策特点探析

蒙古人统治西域后,对各种宗教采取兼容包并的政策,在整体上影响了各种宗教在西域的传播和发展格局。本文对蒙古统治西域时期宗教政策特点进行剖析,除兼容包并的宗教政策特点外,各种宗教在西域的传播发展,在一定程度上还受到蒙古统治者个人或家族的影响。究其宗教政策而言,宗教神权始终置于世俗政权之下,宗教政策具有法律化和延续性。随着历史推移,西域的蒙古人的宗教信仰由最初的萨满教占主导地位逐渐被伊斯兰教逐渐取代。

本文介绍了当前中国低生育率及其相关研究状况,指出社会和人口方面都存在着许多降低生育率的重要因素,而以往研究则因为思想方法问题忽视了它们的存在.本文还就低生育率新时期对人口形势判断及前瞻性研究中的新特点及实际中存在的问题进行了梳理与评论.本文指出,必须及时扭转以往形成的片面观念和思维定势,否则将会在人口发展问题上贻误战机.     

On the orientation relationship between a2 precipitates and the B2 phase in a Ti-47at.%Al-2at.%W-0.5at.%Si alloy

An k -phase Mn-Al-C single crystal was grown and annealed to obtain an intermediate stage of the k M transformation. The crystal was analysed by transmission electron microscopy, and direct evidence for the operation of the shear mode was obtained. The transformation occurs in two steps from the hcp structure ( k ) over the orthorhombic structure ( k ' phase) to the tetragonal phase. The study reveals the morphologies of k ' and , the necessity for reordering during the second transformation step ( k ' M ) which is not a purely martensitic transformation, and the selection of variants which is controlled by stresses through the selection of one k ' variant.
