A multi-perspective multi-domain model of self-concept: structure and sources of self-concept knowledge

A perspective-specific model which deals with the sources of self-concept knowledge as construed by two theories (symbolic interaction and social comparison) was combined with Shavelson's domain-specific model to form a two-facet model of self-concept. The structure of this two-facet model was tapped by a new self-concept instrument, the Multi-Perspective Multi-Domain Self-Concept Inventory (MMSI), which was constructed by crossing domain and perspective facets. Results of confirmatory factor analysis by grade level of the data from a large sample of primary two, four, and six students lent support to the multi-perspective multi-domain model. The MMSI facilitates the estimation of (a) the differential contribution of domain and perspective factors, and (b) the differential contribution of different sources of self-concept knowledge. It also serves as an exemplar of an interesting application of the multi-trait multi-method model in confirmatory factor analysis.     

论现代传染病防治中医患关系的特点

现代传染病防治中传统的医患关系的内涵和外延都发生了一定的变化,无论是医方还是患方都体现出强烈超医学性和社会性,在社会大防治的概念下医患之间出现一定的界限模糊甚至角色重叠。现代传染病的发展给我们提供了审视医患关系的新视角,引发人们关于医学发展、社会道德的深层次的思考。     

中小学教师心理健康状况的调查研究

采用SCL-90对566名教师的心理健康受损情况的调查研究表明：总均分≥2者,占教师总人数的14.2%。从单项因子看,依因子分大于2者所占百分数由少至多依次是精神病性、恐怖、焦虑、躯体化、人际敏感、抑郁、偏执、敌对等,有30.6%的教师有强迫症状。男性教师与女性教师、中学教师与小学教师、任课教师与行政人员的心理健康水平大体相当。乡村教师心理健康水平远远低于城市教师,1~10年教龄的教师远远低于10年以上教龄的教师。

A Field-Tested Task Analysis for Creating Single-Subject Graphs Using Microsoft<Superscript>®</Superscript> Office Excel

Creating single-subject (SS) graphs is challenging for many researchers and practitioners because it is a complex task with many steps. Although several authors have introduced guidelines for creating SS graphs, many users continue to experience frustration. The purpose of this article is to minimize these frustrations by providing a field-tested task analysis for creating SS graphs using Microsoft^® Office Excel. Results from the field test are presented and the task analysis, which includes steps for creating a variety of SS graphs, is provided. The article includes various illustrations, a list of prerequisite skills, tips, and troubleshooting items.     

Moral disengagement moderates the predicted effect of trait self‐control on self‐reported aggression

An increasing number of studies reveal that self‐control is an important preventative factor for aggression. However, the involvement of potential explanatory variables has received less research attention. Drawing upon the feedback‐loop model of self‐control, the current research assumed that the preventing effect of trait self‐control on aggression may be moderated by moral disengagement. Self‐reported measures of trait self‐control, moral disengagement and aggression were administered to 946 Chinese university students. Results show that trait self‐control had a negative effect on physical aggression, verbal aggression, anger and hostility, whereas moral disengagement positively predicted each of these constructs. Of particular importance was a significant interaction between trait self‐control and moral disengagement for verbal aggression and hostility. Specifically, the preventing effect of trait self‐control on these two types of aggression was more pronounced in individuals with low rather than high moral disengagement. In conclusion, low conditional endorsement of transgressive acts and having high trait self‐control are both important individual‐difference variables that explain reduced aggression.     

The Interface Between Core Affects and the Challenge–Skill Relationship

Different models have been developed to describe human experiences. One of these models is the core affect model, which states that the core of emotional experience is a simple state of feeling good or bad, energized or drowsy. Another model is the experience fluctuation model (EFM), which has been developed to map how emotions and other experiences fluctuate along with the relationship between challenges and skills. In this study, we first mathematically refined the EFM. Second, we tested if fluctuations in core affect could be modeled with a continuous wave-like sine function (Study 1). Third, we applied the sine function to our own experience-sampling data, which we collected via mobile phones from 55 university students, and located each challenge–skill relationship in a two-dimensional core affect space (Study 2). The results were consistent in both studies and showed that fluctuations in core affect dimensions, measured as a function of the relationship between challenges and skills, can be modeled with the sine function. The results also indicated that there is a systematic link between challenge–skill relationships and core affect: High challenge–high skill situations were connected to a very active and pleasant core affect, whereas high challenge–low skill situations were connected to a quite active but unpleasant core affect, low challenge–low skill situations to a very passive and unpleasant core affect, and low challenge–high skill situations to a quite passive and pleasant core affect. Compared to previous studies, this study presents a more fine-grained and comprehensive level of information on the relationship between core affect and challenges and skills.     

Ambivalent Versus Univalent Voters: Perceived Media Influences and Third-Person Perceptions

By differentiating “ambivalent” from “univalent” voters, this study argues that ambivalent voters need information to reach a decision, which implies they are more open to persuasion through media coverage than are univalent voters. In turn, they may infer that election coverage exerts a greater influence on them, resulting in smaller self–other perceptual discrepancies in terms of their coverage susceptibility. Conversely, univalent voters have made their voting choices early during the campaign; for them, only when the intended influence seems desirable does the perceived influence of campaign news on them increase, leading to a smaller self–other perceptual gap. In other words, ambivalent voters engage in motivated inferences to reduce their ambivalence-aroused discomfort, whereas univalent voters engage in motivated inferences to avoid dissonance. The results of a survey conducted during the official campaign for the 2012 Taiwanese presidential election support these predictions, demonstrating the utility of categorizing voters as ambivalent or univalent when examining the perceived effects of election campaign news.
