Does Economic Development Affect Life Satisfaction? A Spatial–Temporal Contextual Analysis in China

Social context affects people’s life satisfaction because it provides a natural reference for evaluating their own socioeconomic standing. Given their reference role, social contexts operationalized by space versus time may have very different implications. Our hypothesis is that spatial variation in economic development has little impact on life satisfaction as individuals living in different locales are unlikely to experience this variation personally, but that short-term temporal changes in economic development, on the other hand, do have an impact, as individuals in a given locale experience these changes directly. These two very different implications of spatial versus temporal social contexts are tested with an analysis of repeated survey data in 60 counties of China from 2005 to 2010. The results show that life satisfaction does not vary much with regional differences in economic development but responds positively to the local level of economic development over time. That is, the contextual effects of economic development vary greatly depending on how social context is operationalized. Temporal context matters far more than regional context where individuals’ life satisfaction is concerned.     

内隐和外显记忆任务之间的实验性分离:编码程度和提取要求的作用

通过操纵编码程度(实验1)和提取要求(实验2)比较了内隐和外显记忆任务之间的操作变化.结果表明,编码时的语义和非语义加工之间存在着相互抑制的倾向;提取要求中更多意识成份的参与使先前情节中的语义成份得到更多的提取,而很少影响非语义成份的提取,编码程度和提取要求之间存在着相互作用.     

材料模式与认知负荷对小学生类比学习的影响

探讨学习材料不同模式和学习过程不同的认知负荷对小学生类比推理学习迁移的影响.包括两个分实验.实验1探讨学习材料的不同组织模式对小学生类比推理学习迁移的影响,两组小学生分别学习模式化与非模式化的材料,然后完成迁移程度远近不同的四类测题.结果表明,非模式化条件下完成远迁移题目的成绩显著优于模式化条件下的成绩.实验2探讨小学生在不同认知负荷条件下类比推理学习的迁移效果,两组小学生分别在高认知负荷与低认知负荷情况下学习类比推理的材料,然后完成上述四类测题.结果表明,高认知负荷条件下完成远迁移题目的成绩显著优于低认知负荷条件下的成绩.本实验结果表明,对于小学生类比推理的学习来说,非模式化、高负荷的学习更有利于促进迁移,支持了积极反应理论.

中国女性应该尽快走出迷茫

中国是一个封建统治甚久、封建主义影响很深的国家,也是一个封建意识浓重的国度,在科学高度发达的今天,没落的封建色彩仍有广阔的市场。由于小农经济的思想意识的长期积累,业已渗透到人的个性心理和社会心理之中。所以,迷信盲从的现象有着极其深刻的历史渊源。仅就这一点而论     

复杂图形的双眼视差敏感性

该研究用心理物理学实验方法,以能正确分辨图形在深度上起伏周期数的多少作为判据,检测了七名被试的体视性能。实验结果表明,被试者观看复杂图形的视差敏感性是和图形在深度上变化的复杂程度有关。如果以视差作纵坐标,以图形在深度起伏频率为横坐标,则其深度感知的范围是一个区域,该区域的频率变化范围是从０．１周／度到４周／度,当深度变化频率大于４周／度,则无深度感知。七名被试的双眼深度敏感区有个体差异,但其区域的形状是相似的。     

初中生学业成就动机量表的编制

本研究根据我国初中生的实际编制了一套测量初中生学业成就动机的自陈式量表。该量表由外部行为表现和内部心理因素两个分量表构成。行为表现分置表包括主动性、行为策略和坚持性三个子量表,心理因素分量表包括能力、兴趣、目的、知识价值观四个子量表。测题分析和测验分析的结果表明此量表具有较高的信度和效度,能用于鉴别初中生学业成就动机的水平。     

任务难度对前瞻记忆TAP效应影响的研究

前瞻记忆中的TAP效应是指,当进行中任务和前瞻任务加工类型一致时,前瞻记忆成绩要好于两者工类型不一致时.该研究采用双重任务范式,以大学生为被试,探讨了进行中任务难度对前瞻记忆TAP效应的影响,以揭示注意资源在TAP效应产生中的关键作用.结果表明:当进行中任务难度较低时,没有出现TAP效应,即进行中任务和前瞻任务的加工类型是否一致不会对前瞻记忆成绩产生显著影响;当进行中任务难度较高时,TAP效应部分出现.进一步说,当进行中任务加工类型为语义型时,语义型的前瞻任务成绩要显著好于结构型的前瞻任务成绩;而当进行中任务加工类型为结构型时,前瞻任务的加工类型没有对前瞻记忆成绩产生显著影响.     

生存加工的编码和提取双重优势效应:ERP证据

生存加工比控制条件有更好的记忆表现,产生稳定的记忆优势,这就是记忆生存优势.已有研究多采用行为学实验验证了此现象的存在,但没有确定该优势发生在记忆的何种阶段.本研究采用ERP技术和“间接学习-再认”实验范式,比较被试在生存情境、迁徙情境和愉悦判断中对词汇编码和提取过程的记忆加工,结果发现:在500-700ms时间段,生存情境的相继记忆效应显著大于迁徙情境和愉悦判断:在400-600ms时间段,生存情境的新旧效应显著大于迁徙情境和愉悦判断.表明生存加工具有编码和提取双重优势.     

Characterisation of magnesium oxide and its interface with α-Mg in Mg–Al-based alloys

Magnesium oxide (MgO) films and particles have been collected by pressurised filtration of a Mg-8.6wt%Al-0.67wt%Zn (AZ91D) alloy melt. The morphology of the oxides and their interfaces with the α-Mg phase were investigated by high-resolution transmission electron microscopy. It was found that the oxide films consisted of large numbers of sub-micrometre-sized MgO particles, and that melt shearing can effectively break up the oxide films and disperse the oxide particles. For the first time, orientation relationships (ORs) of OR I: [1?1?1]_MgO～2° from (0?0?0?1)_α-Mg and (0?1?1)_MgO?//[2?1?1?0)_α-Mg; and OR II: (1?1?1)_MgO//(1?1?0?1)_α-Mg and [0?1?1]_MgO//[1?2?1?1]_α-Mg, were observed between the MgO particles and the α-Mg matrix. The calculated Bramfitt planar disregistries were 5.5% and 2.5% for the two ORs, respectively, indicating good lattice matching between MgO and α-Mg at the interface. With the evidence of grain refinement effect observed in the sheared AZ91D magnesium alloy, the possibility of MgO particles to act as potent nucleants for heterogeneous nucleation of α-Mg grains is discussed in terms of the crystallographic criterion.
