影响视觉复合刺激中整体和局部性质加工的几种因素

文章研究了视知觉组织,空间位置不确定性和视野位置等因素对复合刺激中整体和局部性质加工的影响。实验发现,（１）当复合刺激呈现在白背景上时,反应时和干扰作用都表明复复合刺激中大图的加工优于小图,刺激位置的不确定削弱大图对小图的干扰作用;而当复合刺激呈现在由“＋”组成的背影或时,小图的加工优于大图,刺激位置的不确定延长分辩小图的ＲＴ;（２）与周国刺激相比,分辨视野中央的复合刺激的ＲＴ较短,这种影响对分辨     

在押毒品犯人格的基本特征及其相关因素的研究

本研究以 3 78名在押毒品犯为被试 ,以CPI为测量工具 ,探讨了在押毒品犯的基本特征和类型特征 ,并采用方差分析技术研究了影响毒品犯人格的若干因素。结果发现 ,与对照组相比 ,在押毒品犯除了在“自我控制”分量表上未发现显著差异外 ,其余的 1 9个分量表上均有显著差异 ;在押毒品犯在四种人格类型上的分布不平衡 ,主要集中在Delta类型 ;年龄、关押时间对毒品犯的人格特征的变异有一定影响 ,而减刑次数的影响不显著     

沟通、意义和组织化行动研究

组织化行动对组织发展和学习意义很大。有一种观点认为,组织化行动由成员之间的共识而引发;但又有另一种观点认为组织化行为产生的基础在于交换而不在于共识。本研究试图综合以上两种看法,指出等效型意义能够带来组织化或集体性行为。有效的沟通机制能够创造维持等效型意义。     

The Role of School-based Group Mentoring in Promoting Resilience among Vulnerable High School Students

This study examined the role of participation in a year-long school-based group mentoring program, Project Arrive (PA), on increasing resilience during the first year of high school among students identified as being at high risk for school dropout. Participants were 114, ninth grade students taking part in one of 32 PA mentoring groups, and 71 statistically matched comparison students (53% male, 75% eligible for free/reduced-price lunch, 62% Latinx). Using a propensity score with inverse probability of treatment weighting (IPTW) to reduce selection bias, and a multi-level model to account for non-independence of data within mentoring groups, we examined changes from pre-test to program exit on seven external resilience resources (developmental supports and opportunities) and four internal resilience assets (personal strengths). At program exit, PA participants had higher adjusted means than comparisons on six external resources, including school support, school belonging, school meaningful participation, peer caring relationships, prosocial peers, and home meaningful participation. PA participants also had higher adjusted means on one internal asset, problem solving. Results point to the promise of group mentoring as an approach for increasing resilience among academically vulnerable adolescents.     

Transformation of Miller indices in twinned structures

Abstract

The parent–twin transformation equations derived by Mügge and subsequent workers have been reinvestigated in view of the observation that these equations produce similar, but not numerically identical, transformations. The current study suggests that, from the point of view of the classical orientation relations, the assumptions made in several derivations are applicable only to special transformation situations.     

汉字属性匹配与大脑两半球协同活动

在识别汉字时,大脑两半球同时加工的作业成绩是否随加工阶段的增加而显出优势。本研究用汉字形、音、义三种属性分别相匹配的方法用用指定指定提取法,所得实验结果一致表明,形似材料双侧视野同时识别与单侧视野识别成绩无显著差别,而同音与近义材料则表现出双侧呈现显著优于单侧呈现的作业成绩。最后结合脑功能成像研究,对加工阶段影脑半球佃同活动的原因进行了讨论。     

Different paths to protest: predictors of collective action in the Occupy Movement

This study investigated the variables that shaped people's willingness to engage in collective action in the context of the Occupy Movement. Data were collected in 2011 from nonprotesting supporters at the New York City Occupy encampment and active occupiers at the New York and Atlanta encampments. Participants distinguished between different kinds of collective action based on cost. Furthermore, different predictors motivated distinct kinds of collective action. Identity and anger predicted low‐cost collective action. Efficacy predicted relatively costly collective action and mediated the link between identity and costly collective action. This study provides evidence that people draw distinctions between different actions based on cost and that, when it comes to predicting collective action, these distinctions matter.     

Joint Maximum Likelihood Estimation for Diagnostic Classification Models

Joint maximum likelihood estimation (JMLE) is developed for diagnostic classification models (DCMs). JMLE has been barely used in Psychometrics because JMLE parameter estimators typically lack statistical consistency. The JMLE procedure presented here resolves the consistency issue by incorporating an external, statistically consistent estimator of examinees’ proficiency class membership into the joint likelihood function, which subsequently allows for the construction of item parameter estimators that also have the consistency property. Consistency of the JMLE parameter estimators is established within the framework of general DCMs: The JMLE parameter estimators are derived for the Loglinear Cognitive Diagnosis Model (LCDM). Two consistency theorems are proven for the LCDM. Using the framework of general DCMs makes the results and proofs also applicable to DCMs that can be expressed as submodels of the LCDM. Simulation studies are reported for evaluating the performance of JMLE when used with tests of varying length and different numbers of attributes. As a practical application, JMLE is also used with “real world” educational data collected with a language proficiency test.     

Linking Maternal Socialization of Positive Emotions to Children’s Behavioral Problems: The Moderating Role of Self-Control

Little is known about how parents socialize children’s positive affect regulation during late childhood. Consequently, we examined how mothers’ reported responses to their children’s (aged 7–12 years) positive emotions were linked to children’s behavioral problems and how children’s self-control moderated these associations. Our results indicated that maternal encouragement of positive emotions predicted fewer externalizing behaviors, but only for youth with lower self-control. Maternal explanation about their children’s positive emotions was unrelated to youth’s behavioral problems. Lastly, maternal dismissing responses to their children’s positive emotions (i.e., reprimanding responses and discomfort) were related to more externalizing and internalizing in youth, and these effects were not dependent on the children’s self-control. The current study adds to the limited research on positive affect socialization and offers some evidence that youth’s self-control may serve as a vantage-sensitivity factor in the association between maternal positive affect socialization and youth adjustment.
