The information content of panoramic images II: view-based navigation in nonrectangular experimental arenas

Two recent studies testing navigation of rats in swimming pools have posed problems for any account of the use of purely geometric properties of space in navigation (M. Graham, M. A. Good, A. McGregor, & J. M. Pearce, 2006; J. M. Pearce, M. A. Good, P. M. Jones, & A. McGregor, 2004). The authors simulated 1 experiment from each study in a virtual reality environment to test whether experimental results could be explained by view-based navigation. The authors recorded a reference image at the target location and then determined global panoramic image differences between this image and images taken at regularly spaced locations throughout the arena. A formal model, in which an agent attempts to minimize image differences between the reference image and current views, generated trajectories that could be compared with the search performance of rats. For both experiments, this model mimics many aspects of rat behavior. View-based navigation provides a sufficient and parsimonious explanation for a range of navigational behaviors of rats under these experimental conditions.     

Group problem-solving among teachers: A case study of how to improve a colleague’s teaching

A case study of six teachers cooperating to improve a teacher’s teaching showed the dynamics of the group problem-solving process. An analysis of their verbal interactions showed the importance of shared understanding to successful group problem solving. The cooperative group structure helped members resolve cognitive conflicts and build group understanding. During this process, the members’ past teaching experiences and knowledge contributed to their conceptualization of the teacher’s teaching problems and their proposed solutions to improve the teacher’s teaching. Tsz Cheung Lam graduated from the Department of Educational Psychology at the Chinese University of Hong Kong in 2004 and obtained his Master of Education degree. His research interests lie primarily on cooperative learning and problem solving. As a primary school teacher in practice, he is now studying part-time for another master degree in data science at the Department of Statistics of the Chinese University of Hong Kong.     

Quality of Work Life as a Mediator Between Emotional Labor and Work Family Interference

Purpose  We adopted the conservation of resources model (COR, Hobfoll Am Psychol 44:513–524, 1989; Hobfoll in Stress, culture, and community: the psychology and philosophy of stress, Plenum, New York, 1998) to examine the associations among emotional labor, work family interference, and quality of work life. Design/Methodology/Approach  Cross-sectional, self-reported data were obtained from 442 Hong Kong Chinese service employees. Findings  Correlation and hierarchical regression analyses showed that surface acting was a salient correlate of work-to-family interference, even when organizational display rules and employees’ demographic information were controlled. Furthermore, quality of work life had partially mediated the relationship between surface acting and work-to-family interference. However, deep acting and expression of naturally felt emotion did not relate to work-to-family interference. Finally, we found that family-to-work interference was a salient correlate of the use of surface acting in workplace. Implication  This study provided useful information of how adopting different emotional labor strategies related to work family interference. Based on our results, the use of deep acting should be promoted in workplace because it related positively to quality of work life and it did not amplify the work-to-family interference. Originality/value  While past studies often explored the role of emotional labor as the precursor of work family interference, our study is among the first attempt to examine family-to-work interference as the antecedent of emotional labor. Additionally, we had also confirmed the role of quality of work life as an important mediator between emotional labor-work-to-family interference.     

Emulation vs. indigenization in the reception of western psychology in Republican China: An analysis of the content of Chinese psychology journals (1922–1937)

The present study examines the practice of empirical psychology in China during the Republican period using a content analysis of its journals. By seeking answers to questions of what kinds of psychology from the West first attracted the Chinese; whether they found a way of developing a psychology more in tune to their own cultural assumptions of selfhood; and to what uses they felt the new discipline could be put, it shows the extent to which its journal content adopted a Western or an indigenous orientation. It thus contributes to the recent debate about indigenization of psychology globally and situates the origins of these issues in China much earlier than has been envisaged by contemporary Chinese indigenous psychologists. Throughout this period, indigenous concerns informed the research agenda, the dominant practice being psychometrics. But because of a lack of social support, they remained largely confined to the pages of psychology journals. © 2009 Wiley Periodicals, Inc.     

Self-discrepancy and Depressive Experiences among Chinese Early Adolescents: Significance of Identity and the Undesired Self

The paper addresses the cultural bias in the conceptualization and assessment of the self construct inherent in self-discrepancy theory proposed by Higgins. It argues that discrepancies between actual and undesired selves conceived in terms of salient identity should be better predictors of depressive experiences among Chinese early adolescents than the popular notion of actual:ideal discrepancies conceived in terms of individuated self. Eighty-four Chinese early adolescents drawn from the normal population in Hong Kong participated in the study, adopting a short-term two-wave prospective design. Empirical support was obtained showing that self-discrepancies conceived in terms of salient identity and discrepancies between actual and undesired selves were stronger predictors of depressive experiences over time. The findings were interpreted from the perspectives of Chinese culture and the development of self understanding.     

Effects of Gender and Profession Type on Definitions of Violence Against Women in Hong Kong

This study investigated the criteria chosen by male and female Chinese public servants (clinical psychologists, social workers, police officers, physicians, nurses, teachers, and lawyers) in Hong Kong to classify and define violence against women. Data were gathered via questionnaires completed by 2589 (686 male) public servants from 10,476 polled (response rate 24.7%). The questionnaires included a 14-item check-list of various behaviors constituting violence against women and a 10-item check-list of criteria that could be used to categorize behavior as violence against women. It was found that for this population, use of physical force and lack of consent were the main determinants of violence against women. Only half of respondents considered murder a form of violence against women, the rest categorized it as a crime that was "not merely violence." Most respondents defined sexual harassment, rape, and unwanted physical contact as forms of violence against women. The female public servants were more likely to define behaviors as violence against women and to use more criteria to define violence against women. Public servants who worked with the law enforcement and legal system were more likely than others to choose narrow definitions and rigid criteria.     

Accounting for Missing Correlation Coefficients in Fixed-Effects MASEM

Meta-analytic structural equation modeling (MASEM) is increasingly applied to advance theories by synthesizing existing findings. MASEM essentially consists of two stages. In Stage 1, a pooled correlation matrix is estimated based on the reported correlation coefficients in the individual studies. In Stage 2, a structural model (such as a path model) is fitted to explain the pooled correlations. Frequently, the individual studies do not provide all the correlation coefficients between the research variables. In this study, we modify the currently optimal MASEM-method to deal with missing correlation coefficients, and compare its performance with existing methods. This study is the first to evaluate the performance of fixed-effects MASEM methods under different levels of missing correlation coefficients. We found that the often used univariate methods performed very poorly, while the multivariate methods performed well overall.     

Parental, peer, and teacher influences on the social behavior of Hong Kong Chinese adolescents

Intensive interviews and self-report questionnaires were used to investigate parental, peer, and teacher influences on the prosocial and antisocial behaviors of Hong Kong Chinese adolescents. Students came from 5 academically different high schools. Results indicated that perceived parental influence was positively associated with frequency of prosocial behavior and negatively associated with frequency of delinquent behavior. Students with good relationships with their parents and peers showed lower frequencies of antisocial behaviors than did students with bad relationships. Adolescents in different identity statuses (achievement, moratorium, foreclosure, diffusion; E. H. Erikson, 1968) showed different patterns of prosocial and antisocial behaviors. For example, adolescents in the identity achievement group exhibited high frequencies of prosocial behaviors and low frequencies of antisocial behaviors, but those in the identity moratorium group exhibited quite high frequencies of both prosocial and antisocial behaviors.
