The change in perceived motor competence and motor task values during elementary school: A longitudinal cohort study

Participation in motor activities is essential for social interaction and life satisfaction in children. Self‐perceptions and task values have a central position in why children do or do not participate in (motor) activities. Investigating developmental changes in motor self‐perceptions and motor task values in elementary school children would provide vital information about their participation in motor activities. We therefore examined the change in, and associations between, self‐perceptions and task values of fine motor competence, ball competence, and athletic competence in 292 children from kindergarten to grade 4. We also investigated differences between boys and girls, and between children with motor problems and typically developing children. Results indicated that self‐perceptions and task values are domain specific and differ between boys and girls, but not between children with motor problems and typically developing children. Self‐perceptions were not associated with task values. Educators should address specific self‐perceptions to enhance participation into the corresponding motor activities in children between kindergarten and grade 4, and differences in self‐perceptions and task values between boys and girls should be taken into account.     

教师集体效能理论及其应用

教师集体效能是教师效能在集体水平上的扩展,是教师对其作为一个整体的、能够组织和实施影响学生行为过程的能力知觉和信念,它以知觉到的平均数作为其集体效能测量的整合分数。教师集体效能在学生的学业成就、有效学校的特性以及教师的心理与行为的改变中有着重要的应用。但与教师个体效能相比,教师集体效能的研究在整体上还存在着明显的不足     

Reliability and validity of the self‐perception profile for adolescents: An Australian sample

In this study, we explored the psychometric properties and factorial validity of Harter's Self‐Perception Profile for Adolescents (SPPA) with an Australian sample drawn from the Raine study 14‐year follow‐up. Participants, boys (n = 795) and girls (n = 758) from Grades 8, 9, and 10, completed the SPPA. Cronbach's alpha showed good internal reliabilities for seven of the eight subscales and global self‐worth. Boys had significantly higher athletic (p < .001), physical appearance (p < .001), and romantic (p < .05) self‐perceptions, while the girls perceived significantly higher behavioural conduct (p < .001) and close friendships (p < .001). Exploratory factor analysis yielded similar factors to those reported by Harter with North American adolescents, although cross loadings resulted in one additional factor. Our findings generally supported Harter's conceptualisation of the self as a multidimensional construct, and with minor modifications, the use of the SPPA with Australian adolescents.     

Perceptions of Sense of Control,Relative Deprivation,and Expectations of Young Jews and Palestinians in Israel

Abstract

The author focused on the impact of personal deprivation, sense of control, and social context on the future expectations of advantaged and discriminated groups. Analysis of 6,430 Jewish and Palestinian high school students in Israel showed that Palestinian students had lower expectations and stronger feelings of deprivation than Jewish students. Also those who felt deprived had lower expectations regarding the prospects of marriage and the probability of owning a home and a car and of holding a permanent job. However, sense of control influenced these expectations more than did feelings of deprivation. The findings indicated that the processes by which future expectations are formed might be different for Jewish and Palestinian students and that these differences are—at least in part—related to long-term discrimination against Palestinians in Israel.     

Why are some people more susceptible to ingroup threat than others? The importance of a relative extrinsic to intrinsic value orientation

Whereas an individual differences perspective recently pointed to the importance of a relative extrinsic to intrinsic value orientation in the prediction of outgroup attitudes, the intergroup relations perspective stresses the importance of threat. This study investigates the interplay of both perspectives. A scenario study among high-school students showed that only people who attach greater relative importance to extrinsic values react with a negative attitude towards an outgroup that is portrayed as threatening. A longitudinal study among university students then showed that people with a relatively greater extrinsic value orientation are not only more likely to react to threat but also to perceive threat. Specifically, cross-lagged analyses showed that a relatively greater extrinsic value orientation predicted over-time increases in threat perceptions.     

工作场所中他人感知的员工工作-家庭冲突：刻板印象视角

以往研究发现工作场所中他人感知的员工工作-家庭冲突对员工工作结果具有重要影响, 但相关研究处于起步阶段。在文献回顾的基础上, 从刻板印象理论出发, 提出可能影响他人感知员工工作-家庭冲突的工作、家庭相关因素; 采用能力-热情维度框架探讨他人感知员工工作-家庭冲突的作用机制及其结果。今后研究可在整合工作-家庭冲突研究和刻板印象理论的基础上, 对他人感知员工工作-家庭冲突的形成及人际效用机制等方面进行拓展。     

Package size and perceived quality: The intervening role of unit price perceptions

This research examines how package size can influence quality judgments for packaged goods, and also identifies a price-based mechanism for the observed size–quality relationship. Results from several studies show that a product in a smaller package is rated more favorably than the equivalent product in a larger package. Further, this effect is due to the smaller package being associated with a higher unit price (despite having a lower overall price), which suggests that unit price information is more diagnostic than overall price information when forming judgments of product quality. We also find a theoretically-derived reversal of this effect under conditions in which the greater diagnosticity of unit price is overwhelmed by its lower ease of use. Namely, when overall price is the only explicitly-provided price cue and consumers are too distracted to estimate unit price, a larger package is now rated as being better. Finally, two concluding studies examine the downstream consequences of changes in package size, building off our basic conceptualization to document effects on product choice as well as consumption experience.     

Research into therapists’ perceptions of therapeutic change using vignettes and aMSN messenger

This article describes a research approach to investigating the ways in which therapists understand the nature of therapeutic change. The research was based in qualitative, narrative approaches to in-depth analysis of vignettes provided by drama therapists. The article describes the approach to the generation of data through the internet by aMSN messenger. It reports on the approach taken to the analysis of data along with samples from the findings.
