Likert量表分析中不同IRT模型的有效性

5级Likert量表可直接分析,也可以转化为3级评分,或转化为2级评分。前二者可以采用等级IRT模型,后者可以采用2级IRT模型。研究表明2级IRT模型中的2参数模型是最适合的模型。多级评分模型与数据拟合也很好,而且等级越多测量精度越大。     

Small wonders of the Indian market

Heavy competition in India in almost all product categories, due to diversification by large and medium companies and increased entry of multinationals, has restricted the growth of domestic companies. Previously, large companies enjoyed high profit margins by targeting premium priced products in the upper strata of Indian society. High levels of competition from equally reputed brands have not only decreased the companies' market share but also created price wars, reducing profit margins and limiting market growth. This has motivated companies to consider the lower classes and the rural segments, which they had previously ignored. By targeting these segments with products in small packs at lower price points, companies have experienced great success. At the same time, small packs also pose some challenges for the companies. This paper explains the importance of small packs for market expansion in various product categories within the Indian market, drawing on several examples to support the views of the authors.

心理健康素质测评系统·中国成年人生活信念量表的编制

本研究的目的是编制适合中国社会文化特点的生活信念量表。通过搜集整理已有相关文献,并考虑《心理健康素质测评系统》的整体结构,确定了该量表的合理性和可控性两维度的理论构想。通过参考国外同类量表项目以及在心理学专家中征集项目的方式形成初始量表,并通过预测筛选确定量表的最终项目。测试结果表明,生活信念量表具有较高的重测信度、内部一致性信度和较高的结构效度、内容效度、聚合效度以及同时效度。结论：生活信念量表具备令人满意的心理测量学特征,可以被用来评估中国成年人的生活信念。     

Processing spatial relations with different apertures of attention

Neuropsychological studies suggest the existence of lateralized networks that represent categorical and coordinate types of spatial information. In addition, studies with neural networks have shown that they encode more effectively categorical spatial judgments or coordinate spatial judgments, if their input is based, respectively, on units with relatively small, nonoverlapping receptive fields, as opposed to units with relatively large, overlapping receptive fields. These findings leave open the question of whether interactive processes between spatial detectors and types of spatial relations can be modulated by spatial attention. We hypothesized that spreading the attention window to encompass an area that includes two objects promotes coordinate spatial relations, based on coarse coding by large, overlapping, receptive fields. In contrast, narrowing attention to encompass an area that includes only one of the objects benefits categorical spatial relations, by effectively parsing space. By use of a cueing procedure, the spatial attention window was manipulated to select regions of differing areas. As predicted, when the attention window was large, coordinate spatial transformations were noticed faster than categorical transformations; in contrast, when the attention window was relatively smaller, categorical spatial transformations were noticed faster than coordinate transformations. Another novel finding was that coordinate changes were noticed faster when cueing an area that included both objects as well as the empty space between them than when simultaneously cueing both areas including the objects while leaving the gap between them uncued.     

Distinguishing three levels in explicit self-awareness

This paper focuses on the development of explicit self-awareness in children. Mirror self-recognition has been the most popular paradigm used to assess this ability in children. Nevertheless, according to Rochat (2003), there are, at least, three different levels of explicit self-awareness. We therefore designed three different self-recognition tasks, each corresponding to one of these levels (a mirror self-recognition task, a picture self-recognition task and a masked self-recognition task). We observed a decrease in performance across the three tasks. This supports a developmental scale in self-awareness. Besides, the masked self-recognition performance makes it possible to assess the final and the most sophisticated level of self-awareness, i.e. the external self. To our best knowledge, this task is the first attempt to evaluate the external self in preverbal children. Our results indicate that 22-month old children show awareness of their external self or, at least, that this ability is in the process of being acquired.     

Impact of Jin‐Shang teachings on Chinese people's trust

Three studies are reported that explore the impact of Jin‐Shang teachings (a specialized Confucius teaching of trust on business practices) on mainland Chinese people's trust. In Study 1 , we primed Confucius and Jin‐Shang teachings on trust, and compared their effects on trusting tendency to a control prime. We found that these teachings made mainland Chinese participants score higher on three different trusting scales. In Study 2 , we found that the Jin‐Shang prime made mainland Chinese participants invest more money in a trust game than those in the control prime. In Study 3 , we compared the Jin‐Shang prime to Protestant teachings and contemporary writings on reciprocity, and found that only the Jin‐Shang prime induced a significantly higher trusting tendency from Chinese participants than the control condition.     

Cross‐cultural validation of factor structure in the Japanese Counselor Burnout Inventory

This article describes the cross‐cultural validation of the Counselor Burnout Inventory (CBI; Lee, Baker, Cho, Heckathorn, Holland, Newgent, Ogle, Powell, Quinn, Wallace & Yu, 2007 ) on a sample of professional counselors and psychotherapists in Japan. Confirmatory factor analysis was performed to examine the validity of the CBI with three models: a one‐factor model, a five‐factor model, and a second‐order model. The results showed that the five‐factor model was a better fit and more parsimonious than both the one‐factor model and the second‐order factor model. Additionally, the internal consistency reliability for the CBI subscale scores proved equivalent to that found for other populations (e.g. American and Korean). The results suggest that counselor burnout is not a unidimensional construct but a multidimensional construct. Implications and recommendations for future research are provided.     

Self-Efficacy in Service-Learning Community Action Research: Theory, Research, and Practice

The purpose of this article is threefold: In the first section, an overview of research and theory on the self-efficacy construct is provided, and the central role of self-efficacy in service-learning community action research is demonstrated. The second section reviews over 10 years of research validating the Community Service Self-Efficacy Scale (CSSES), which measures the individual’s confidence in his or her own ability to make clinically (meaningfully) significant contributions to the community through service. Within the context of this review, recent (previously unpublished) validation research is also reviewed. Alternate versions of the CSSES, each of which was developed for a specific purpose, are presented. The third section provides recommendations for further research focused on (a) validating the CSSES and (b) examining self-efficacy as an outcome, moderator, and mediating variable in service-learning community action research.     

重复犯罪罪犯人格特征的分析及预防对策

采用《中国罪犯心理测试个性分测验》(COPA-P)I测量罪犯的人格特征,并对初犯和重复犯罪罪犯的人格特征进行比较。结果发现,在攻击性、报复性、犯罪思维模式这三个因子上,重复犯罪的罪犯明显高于初犯。并具体分析了其人格特点,针对重复犯罪罪犯人格的特殊性,提出了在改造过程中相应的措施。     

偶像崇拜量表的修订及其理论模型的验证

对偶像崇拜量表进行修订获得较好的测量学指标,经探索性因素分析确定的量表条目为27个,得到五个维度分别命名为"娱乐社交"、"情感投射"、"完全认同"、"关系幻想"、"病理边缘",从低到高表示偶像崇拜的不同迷恋程度。经验证性因素分析,该结构具有良好的结构合理性和一致性,不同人口学背景被试共享该理论模型,模型的因素载荷一致性得到完全验证,题目截距一致性得到较大程度验证,可以用作测量青少年偶像崇拜有效工具。
