基于时间投入——专注度双维核心模型的高中生学业勤奋度研究

为避免单维评估存在高估或者低估学生学业勤奋表现的不足,以学业勤奋度研究的"时间(行为)投入"和"专注度"两种取向为基础,提出了高中生学业勤奋度的时间(行为)投入—专注度双维核心模型,并考察386名高中生在该模型上的分布特点,进而检验其应用效果。结果表明:(1)以学业勤奋度的双维核心模型为基础,将学生分为四组,并且这四组学生在时间投入和专注度上的差异表现为:在时间投入上,高时间投入的两个组学生的时间投入水平较高,低时间投入两个组学生的时间投入水平较低;在专注度上的分布也是如此。这说明本研究的分组是有效的。(2)模型能够有效将高中生分组,其中高时间投入—低专注度组所占比例最大(30.4%),其次为低时间投入—低专注度组(28.6%),再次是低时间投入—高专注度组(23.6%),高时间投入—高专注度组所占比例最小(17.4%)。(3)模型在不同总体学业成绩和语文、数学、英语等单科成绩上的分组效应均显著,同时拥有高学习时间(行为)投入和高专注度的高中生具有最佳的总体和单科学业成绩。因此,学业勤奋度的学习时间(行为)投入—专注度模型具有良好的应用效果。     

网络成瘾的潜在结构:连续的还是分类的?

变量的潜在结构是连续的还是分类的不应被随意指定,错误的设定可能导致不正确的结论。本研究的目的在于从实证的角度探索网络成瘾的潜在结构。研究采用了来自中国杭州的2511名初中生对Young网络成瘾量表的有效作答数据,比较了Rasch模型、潜在类别模型和混合Rasch模型与数据的拟合情况。结果表明:2个潜在类别的混合Rasch模型可以最好地反映网络成瘾的潜在结构,说明网络成瘾包含两个存在着质的差异的群体,并且每个群体内的个体间存在量的差异。研究进一步比较了基于混合Rasch模型的分类与传统划界分数分类的区别,结果表明:Young的网络成瘾标准可能具有很小的误判率和较高的漏判率;基于Young网络成瘾测验的修订需要考虑有针对性地增加部分题目。     

外来务工女性刻板印象威胁的应对策略与认同管理

为了探讨外来务工女性群体刻板印象威胁的应对策略和认同管理,从天津市WX社区通过滚雪球抽样方法选取124名外来务工女性作为被试,采用问卷调查的形式,测查了外来务工女性群体刻板印象应对策略和认同管理模式,尤其考察了认同基线水平、认同融合、否定策略和榜样策略对于应对和认同管理的有效性。结果表明：（1）外来务工女性群体具有双重认同趋势;具有较高城市认同融合的外来务工女性群体具有显著的认同维护倾向;（2）不同印象管理水平的外来务工女性对否定策略的使用差异性很小,反而是刻板印象威胁的长期性和暴露性是引发否定策略的重要因素;（3）角色榜样成功的应得性对外来务工女性城市认同感的提高具有积极效应;（4）城市务工年数和收入成为这一群体城市认同的主要影响因素。     

成对数据分析之行动者-对象互依性模型(APIM)

成对关系是人际关系和人际互动的最基本的单元, 对成对关系的测量得到的成对数据具有人际关系的互依性特点, 这种互依性往往体现在对象效应上。考虑到数据的互依性以及同时估计行动者效应和对象效应的行动者-对象互依性模型(APIM)是一种相对简单但很有吸引力的指导分析的模型。成对数据中根据数据的变异源分为三种变量; 根据是否存在可区分开成对关系中的双方的变量而分为可区分和不可区分的数据; 成对数据的分析往往开始于互依性程度的检验; 在独立性不能得到满足的情况下, 考虑是否可区分, 则可以采用联合回归、多水平模型, 结构方程建模的方法, 对APIM中的各个效应进行估计。其中, 尤为详细地介绍了使用LISREL软件进行结构方程建模分析的方法。     

Definability and Invariance

In his thesis Para uma Teoria Geral dos Homomorfismos (1944), the Portuguese mathematician José Sebastião e Silva constructed an abstract or generalized Galois theory, that is intimately linked to F. Klein’s Erlangen Program and that foreshadows some notions and results of today’s model theory; an analogous theory was independently worked out by M. Krasner in 1938. In this paper, we present a version of the theory making use of tools which were not at Silva’s disposal. At the same time, we tried to keep in mind, so much as possible, the gist of his standpoint.     

Longer you play, the more hostile you feel: examination of first person shooter video games and aggression during video game play

This study investigated the effects of video game play on aggression. Using the General Aggression Model, as applied to video games by Anderson and Bushman, [2002] this study measured physiological arousal, state hostility, and how aggressively participants would respond to three hypothetical scenarios. In addition, this study measured each of these variables multiple times to gauge how aggression would change with increased video game play. Results showed a significant increase from baseline in hostility and aggression (based on two of the three story stems), which is consistent with the General Aggression Model. This study adds to the existing literature on video games and aggression by showing that increased play of a violent first person shooter video game can significantly increase aggression from baseline.     

Marital satisfaction and depression: a replication of the Marital Discord Model in a Latino sample

The Marital Discord Model of Depression maintains that marital discord is an important antecedent in the development of depression. Although empirical evidence supports this premise, none of this research has been done with Latinos. The purpose of this study was to test the longitudinal relationship between marital satisfaction and depression among 99 Brazilian women. Using structural equation modeling, results indicated that marital satisfaction was a strong predictor of depression 2 years later. Marital satisfaction was also related to cooccurring depression. These results provide evidence that the Marital Discord Model of Depression is an appropriate theoretical model for the conceptualization of marital discord and depression with Latina women and suggest the potential utility of using couples therapy for treating depression among this population.     

"What if…": The Use of Conceptual Simulations in Scientific Reasoning

The term conceptual simulation refers to a type of everyday reasoning strategy commonly called "what if" reasoning. It has been suggested in a number of contexts that this type of reasoning plays an important role in scientific discovery; however, little direct evidence exists to support this claim. This article proposes that conceptual simulation is likely to be used in situations of informational uncertainty, and may be used to help scientists resolve that uncertainty. We conducted two studies to investigate the relationship between conceptual simulation and informational uncertainty. Study 1 was an in vivo study of expert scientists; the results suggest that scientists do use conceptual simulation in situations of informational uncertainty, and that they use conceptual simulation to make inferences from their data using the analogical reasoning process of alignment by similarity detection. Study 2 experimentally manipulated experts' level of uncertainty and provides further support for the hypothesis that conceptual simulation is more likely to be used in situations of informational uncertainty. Finally, we discuss the relationship between conceptual simulation and other types of reasoning using qualitative mental models.     

"大七"人格结构模型下的汉族、纳西族人格结构比较

Relatedness of identities and emotional closeness with parents across and within cultures

Differences in emotional- and identity-relatedness with parents were explored across two cultural groups (863 university students from the USA and Turkey, representing individualist and collectivist societies, respectively) in Study 1 , and across two socioeconomic status (SES) groups (353 high school students from the upper and lower SES in Turkey) in Study 2 . In both studies, within-cultural differences in emotional- and identity-relatedness with parents were also explored in terms of: (i) self-directed and other-directed value orientations; and (ii) self-types, as suggested by the Balanced Integration-Differentiation Model. Results indicated cultural groups to be quite similar in emotional-relatedness, but to differ in relatedness of identities, with Turks reporting more related identities. Similarly, in Turkey, SES seemed to have more impact on identities than on emotional closeness, the lower SES adolescents reporting more relatedness with parents than upper SES adolescents. Thus, relatedness of identities appeared to be more important than emotional relatedness in differentiating between cultural and SES contexts. Results involving different self-types and value orientations pointed to both cross-cultural similarities and within-cultural diversity in the two domains of relatedness. Theoretical implications of cross- and within-culture differences in emotional- and identity-relatedness with parents are discussed.
