Aging of theory of mind: The influence of educational level and cognitive processing

Previous studies of theory of mind (ToM) in old age have provided mixed results. We predicted that educational level and cognitive processing are two factors influencing the pattern of the aging of ToM. To test this hypothesis, a younger group who received higher education (mean age 20.46 years), an older group with an education level equal to that of the young group (mean age 76.29 years), and an older group with less education (mean age 73.52 years) were recruited. ToM tasks included the following tests: the second‐order false‐belief task, the faux‐pas task, the eyes test, and tests of fundamental aspects of cognitive function that included two background tests (memory span and processing speed) and three subcomponents of executive function (inhibition, updating, and shifting). We found that the younger group and the older group with equally high education outperformed the older group with less education in false‐belief and faux‐pas tasks. However, there was no significant difference between the two former groups. The three groups of participants performed equivalently in the eyes test as well as in control tasks (false‐belief control question, faux‐pas control question, faux‐pas control story, and Eyes Test control task). The younger group outperformed the other two groups in the cognitive processing tasks. Mediation analyses showed that difficulties in inhibition, memory span, and processing speed mediated the age differences in false‐belief reasoning. Also, the variables of inhibition, updating, memory span, and processing speed mediated age‐related variance in faux‐pas. Discussion focused on the links between ToM aging, educational level, and cognitive processing.     

Models with discrete latent variables for analysis of categorical data: A framework and a MATLAB MDLV toolbox

Studies in the social and behavioral sciences often involve categorical data, such as ratings, and define latent constructs underlying the research issues as being discrete. In this article, models with discrete latent variables (MDLV) for the analysis of categorical data are grouped into four families, defined in terms of two dimensions (time and sampling) of the data structure. A MATLAB toolbox (referred to as the “MDLV toolbox”) was developed for applying these models in practical studies. For each family of models, model representations and the statistical assumptions underlying the models are discussed. The functions of the toolbox are demonstrated by fitting these models to empirical data from the European Values Study. The purpose of this article is to offer a framework of discrete latent variable models for data analysis, and to develop the MDLV toolbox for use in estimating each model under this framework. With this accessible tool, the application of data modeling with discrete latent variables becomes feasible for a broad range of empirical studies.     

群体独特性对群际偏差的影响

群体独特性影响群体认同,较高或较低的群体独特性都可能引发群际偏差,分别称为“反射式独特性假说”与“反应式独特性假说”.调节作用研究揭示,在较低群体认同或上位群体分类凸显时,群体独特性越高越易引发群际偏差;而在较高群体认同时,独特性越低越易引发群际偏差.动机作用的研究表明,在具有群际竞争目标时,这两种过程分别受工具性动机与认同性动机的驱动.情绪与认知的中介作用研究显示,在低独特性条件下,社会身份复杂性与焦虑情绪可起中介作用引发群际偏差.     

基于潜在类别分析的6~15岁儿童平衡秤任务认知规则探索

本研究使用自编平衡秤测验测试468名6~15岁儿童,通过潜在类别分析对认知规则进行分类。结果发现,被试使用了规则Ⅰ、规则Ⅰ'、规则Ⅱ、补偿规则、规则Ⅳ、距离优势规则等六种规则;6~9岁儿童主要使用规则Ⅰ;10~13岁儿童主要使用补偿规则;14岁以上儿童主要使用规则Ⅳ;13岁到14岁之间,使用规则Ⅳ的儿童数量呈跳跃式增加。与规则评估技术相比,潜在类别分析用于认知规则研究具有明显优势,最后对运用此方法的前提假设与局限进行了讨论。     

Abusive supervision and subordinate emotional labor: The moderating role of openness personality

We investigated the differential relationships between abusive supervision and two emotional labor strategies used by subordinates (surface acting and deep acting). Furthermore, we examined whether subordinates' openness personality moderated the above relationships. Using the questionnaire survey method, we collected data from 210 employees in China. The results of hierarchical regression showed that abusive supervision related positively to surface acting (regulating facial expression) but negatively to deep acting (regulating inner feeling). Openness personality moderated the relationships between abusive supervision and the two emotional labor strategies, such that the relationships were stronger for employees with lower openness. Findings of our study contribute to the literature on workplace emotions and negative leadership.     

The impact of the opinions of others on variety‐seeking behavior

One reason for consumer variety‐seeking behavior is interpersonal motivation. Building on previous theories, we suggest that the different information types of interpersonal sources influence the variety‐seeking behavior of individuals. Two laboratory experiments are conducted to examine the influence of the opinions of others on such behavior. The results support the author's contention that to derive more enjoyment from a shared product, an individual will make choices congruent with the opinions of others in online information. The managerial implications and study limitations are also discussed.     

Cross-Cultural Generalizability of the Reactive–Proactive Aggression Questionnaire (RPQ)

In this study, we assessed the cross-cultural generalizability of the Reactive–Proactive Aggression Questionnaire (RPQ) and tested the hypotheses that boys show higher levels of proactive aggression with increasing age and that a two-factor (reactive–proactive) structure will be observed in an East Asian population. We administered the RPQ to 5,615 male and female 11- to 15-year-old schoolchildren. CFA demonstrated a good fit of the two-factor reactive–proactive model. Proactive aggression increased significantly with age in boys but not girls, whereas reactive aggression showed no gender difference and only a minimal age increase. Results suggest the presence of meaningful differences between these aggression subtypes and the generalizability of the RPQ in an East Asian population.

Managing Coworker Assistance Through Organizational Identification

This article investigates how different sources of management support promote coworker helping behavior in organizations. We contend that senior management, managers responsible for Human Resource practices, and team leaders contribute to coworker assistance by encouraging employees to identify with the organization. Based on survey evidence drawn from nine Australian (N?=?1,349 employees) and six Chinese firms (N?=?828 employees), and using structural equation modeling, we show that organizational identification mediates the effects of perceived support from these three sources on coworker assistance. Differences in the strength of relationships between the variables are highlighted and discussed.     

Disclinations and rotational deformation in fine-grained materials

A theoretical model is presented which describes a new mechanism of plastic deformation in fine-grained materials. In the framework of the model, rotational deformation occurs via motion of dipoles of grain-boundary disclinations and is associated with the emission of lattice dislocations from grain boundaries into adjacent grain interiors. Ranges of defect system parameters are identified in which the disclination motion is energetically favourable. It is shown that the mechanism can contribute to plastic flow in fine-grained materials prepared by highly non-equilibrium methods such as ball milling, severe deformation and high-pressure compaction.
