心理学视野下的社会变迁研究：研究设计与分析方法

近年来,社会变迁导致的文化、心理与行为变化及其相互建构已经成为心理学的研究热点。社会变迁研究通常涉及和变迁相关的时间效应、时代效应以及和变迁无关的年龄效应。在考察变迁趋势及其影响因素时,常用的研究设计有跨时间比较、跨代际比较、跨地区比较(历史重构)等方法;常用的分析方法有传统的相关和回归分析和现代的时间序列分析(比如交叉滞后相关和格兰杰因果检验)等。由于每一种设计都有其优点和不足,在具体研究中,研究者要根据研究的问题和可操作性选择合适的方法;如果可能,最好同时采用多种方法,以寻求基于不同方法的聚合证据。     

Hemispheric processing of lexical information in Chinese character recognition and its relationship to reading performance

Hemispheric predominance has been well documented in the visual perception of alphabetic words. However, the hemispheric processing of lexical information in Chinese character recognition and its relationship to reading performance are far from clear. In the divided visual field paradigm, participants were required to judge the orthography, phonology, or semantics of Chinese characters, which were presented randomly in the left or right visual field. The results showed a right visual field/left hemispheric superiority in the phonological judgment task, but no hemispheric advantage in the orthographic or semantic task was found. In addition, reaction times in the right visual field for phonological and semantic tasks were significantly correlated with the reading test score. These results suggest that both hemispheres involved in the orthographic and semantic processing of Chinese characters, and that the left lateralized phonological processing is important for Chinese fluent reading.     

Credal pragmatism

According to doxastic pragmatism, certain perceived practical factors, such as high stakes and urgency, have systematic effects on normal subjects’ outright beliefs. Upholders of doxastic pragmatism have so far endorsed a particular version of this view, which we may call threshold pragmatism. This view holds that the sensitivity of belief to the relevant practical factors is due to a corresponding sensitivity of the threshold on the degree of credence necessary for outright belief. According to an alternative but yet unrecognised version of doxastic pragmatism, practical factors affect credence rather than the threshold on credence. Let’s call this alternative view credal pragmatism. In this paper, I argue that credal pragmatism is more plausible than threshold pragmatism. I show that the former view better accommodates a cluster of intuitive and empirical data. I conclude by considering the issue of whether our doxastic attitudes’ sensitivity to practical factors can be considered rational, and if yes, in what sense.

     

Reverse evolution in nanoscale Cu-rich precipitates of an aged Fe–Cu alloy under electropulsing

Nanoscale Cu-rich precipitates (CRPs) are one of the most important microstructural nano-features responsible for embrittlement and hardening of reactor pressure vessels (RPVs), which threaten the safe operation of nuclear power plants (NPPs) and hinder the lifetime extension of nuclear reactors. A thermally aged Fe-1.1 wt.%Cu alloy, which is used to simulate embrittlement of the irradiated RPV steels, was treated by electropulsing with various parameters. The effect of electropulsing on nanoscale CRPs was investigated by using transmission electron microscopy (TEM). Compared to the traditional heat treatment, the electropulsing treatment (EPT) can accelerate the dissolution of CRPs in an aged Fe-Cu alloy on account of the higher atomic drift flux and the additional Gibbs free energy induced by electropulsing. More importantly, EPT is likely to be a new way of eliminating irradiation-induced Cu-rich precipitates.     

消极刻板印象和群际焦虑:阻碍群际交往的重要因素

消极刻板印象和群际焦虑是阻碍群际交往的重要因素。基于群际接触理论和群际焦虑理论模型,测量了少数民族和汉族交往时的群际焦虑水平、彼此持有的刻板印象和外群体态度等变量,考查了这些变量的特征及关系。结果表明:(1)汉族在群际交往过程中的群际焦虑水平显著高于少数民族;(2)女性比男性持有更积极的外群体态度;(3)消极刻板印象是产生群际焦虑和偏见态度的重要原因。减少消极刻板印象、降低群际焦虑是促进群际交往的重要途径。     

环境条件和兴趣对大学生妥协决策的影响

研究旨在考察个体在选择职业时是否会为了更好的环境条件(组织、城市)而降低对兴趣的要求。对63名大学生被试开展了两个实验,采用在环境条件和兴趣水平上有不同程度差异的职位配对来模拟两难决策。结果发现:(1)对不同组织声望和兴趣水平的职位的选择无性别差异;(2)组织声望差距、组织声望差距与兴趣差距的交互作用能显著预测职位的选择;(3)对不同城市级别和兴趣水平的职位的选择有性别差异,男生比女生更少放弃兴趣;(4)兴趣差距、城市级别差距与兴趣差距的交互作用能预测男生的选择,只有兴趣差距能预测女生的选择。结论:个体会为了更好的环境而或多或少在兴趣方面妥协。     

羞怯对攻击的影响:安全感和社会比较倾向的中介作用

为考察安全感和社会比较倾向在羞怯与攻击之间关系的中介作用,采用大学生羞怯量表、社会比较倾向量表、安全感量表和攻击问卷对543名大学生进行测量。结果发现(1)羞怯、攻击和社会比较倾向三者之间呈显著两两正相关,且三者分别与安全感呈显著负相关;(2)羞怯对攻击的直接效应显著;(3)安全感和社会比较倾向在羞怯与攻击关系间起完全中介作用。     

区分适应性自恋和非适应性自恋:多视角的证据

近40年来, 正常人的自恋得到了越来越多的关注.日益增加的证据显示正常人的自恋可以按照适应功能进一步区分为适应性自恋和非适应性自恋两类.本文对揭示两类自恋差异的证据进行了全面梳理, 包括二者的成分构成,适应功能,人格基础,发展规律和遗传基础.这些结果促进了对自恋复杂性的认识, 加深了对现有研究的理解, 同时也突出了未来区分二者的重要性.将来需要从理论上进一步澄清二者的差异, 编制相应的量表, 探讨二者在其它方面的不同, 特别是二者是否具有不同的神经基础.     

不同社会群体特征对内隐领导因素的影响

研究发现,中国人内隐领导理论的内容由个人品德、目标有效性、人际能力和多面性四个因素构成。不同的年龄、职业和教育水平等评分者的特点,对领导诸因素的评分有着显著的影响。综合分析发现,教育水平是影响内隐领导因素评分的主要变量。另外,各组都倾向于把人际能力作为领导最大的特质来加以评分。     

The dynamics of multimodal integration: The averaging diffusion model

We combine extant theories of evidence accumulation and multi-modal integration to develop an integrated framework for modeling multimodal integration as a process that unfolds in real time. Many studies have formulated sensory processing as a dynamic process where noisy samples of evidence are accumulated until a decision is made. However, these studies are often limited to a single sensory modality. Studies of multimodal stimulus integration have focused on how best to combine different sources of information to elicit a judgment. These studies are often limited to a single time point, typically after the integration process has occurred. We address these limitations by combining the two approaches. Experimentally, we present data that allow us to study the time course of evidence accumulation within each of the visual and auditory domains as well as in a bimodal condition. Theoretically, we develop a new Averaging Diffusion Model in which the decision variable is the mean rather than the sum of evidence samples and use it as a base for comparing three alternative models of multimodal integration, allowing us to assess the optimality of this integration. The outcome reveals rich individual differences in multimodal integration: while some subjects’ data are consistent with adaptive optimal integration, reweighting sources of evidence as their relative reliability changes during evidence integration, others exhibit patterns inconsistent with optimality.
