This study extended the concept of collective efficacy to supplement the variable of career self-efficacy to predict vocational exploration and commitment among adolescents. We developed a Collective Contributions to Career Efficacy Scale (CCCE) to measure adolescents' perceived contributions from parents, teachers, and peers on their career-related matters. A total of 1175 high school students from Hong Kong, Shanghai and Michigan participated in the study by completing the CCCE, the Career Decision Self-Efficacy Scale (CDSE-SF), and the Vocational Exploration and Commitment Subscale (VEC). Using multi-sample Structural Equation Modeling, we found that the effect of CCCE on VEC was mediated by CDSE. Although we found cultural differences in the overall level of the vocational measures among the Hong Kong, Shanghai, and American students, the mediation model was confirmed in all three groups of students.  相似文献

A new test is proposed for the problem of comparing two independent groups in terms of some measure of location. The proposed test () uses a one‐step M‐estimator and a bootstrap‐t method with the procedure proposed by Özdemir and Kurt (2006) . Eight methods were compared in terms of actual Type I error and power when the underlying distributions differ in skewness and kurtosis under heterogeneity of variances. For the 21 theoretical distributions, the Yuen test with the bootstrap‐t method was the most favourable, followed by test. For the five real data sets, the proposed test and percentile bootstrap method with the one‐step M‐estimator performed best.  相似文献

Previous work on human memory has shown that prompting participants with false events and self-relevant information via different types of media such as narratives, edited 2-dimensional images, and mental imagery creates false memories. This study tested a new form of media for studying false memory formation: Immersive Virtual Environment Technology (IVET). Using this tool, we examined how memory was affected by viewing dynamic simulations of avatars performing novel actions. In the study, 55 preschool and elementary children were randomly assigned to 1 of 4 memory prompt conditions (idle, mental imagery, IVET simulation of another child, or IVET simulation of self). Each child was questioned 3 different times: once before the memory prompt, once immediately after the memory prompt, and once approximately 5 days after the memory prompt. Results showed that preschool children were equally likely to develop false memories regardless of memory prompt condition. But, for elementary children, the mental imagery and IVET self conditions caused significantly more false memories than the idle condition. Implications regarding the use of digital media in courtroom settings, clinical therapy settings, entertainment, and other applications are discussed.  相似文献

A model for practising genetic counselors to obtain clinical supervision via reciprocal peer observation and feedback was developed and trialled. The model was developed in response to a perceived lack of opportunity for immediate observational feedback for practising genetic counselors. The aims reached by consensus were to facilitate learning new approaches and skills, to revitalise current ways of practising, and to enhance supervision skills in a two-way process, where the observer learnt from the counselor, and vice-versa. The genetic counselors agreed on a process of paired reciprocal observation whereby the observer was present in the room during the counseling session, and a reflective feedback discussion was arranged within 24 h of the session. Four main themes emerged from analysis of the recorded discussions were (i) “I wasn’t sure if I-”: voicing of doubts or internal questions that occurred during session for the counselor conducting the session, (ii) “I really liked that”: positive feedback and validation from the observer, (iii) “I wonder whether-”: offering of alternative views, insights and strategies by the observer, and (iv) “That’s a real thing for me to take away and think about”: evidence of learning by both observers and counselors.  相似文献

This study examined whether the dimension of reflective processing (e.g., deep and elaborative processing) was connected to the use of relational aggressions, social aggression, or both. A convenience sample of 629 college students (66% female, 91.6% White) was surveyed to ascertain the relation between self-reported relational and social aggression and deep and elaborative processing. The overall multivariate regression model was significant, Wilks’s λ = .12, F(4, 2162) = 1010.80, p < .001. Univariate results were used to show that the two predictors (relational and social aggression) significantly and strongly positively predicted the use of deep processing, R2 = .81, p < .001, as well as the use of elaborative processing, R2 = .87, p < .001. In summary, higher levels of social and relational aggression were related to higher levels of deep and elaborative processing. Implications for these findings are presented.  相似文献

Transactive memory theory suggests that general awareness of expertise location in a group is sufficient to predict expertise seeking. Yet expertise seeking is, at least in part, a social phenomenon between two individuals embedded in a network of social relationships. Taking a multilevel, network perspective, we examined the interplay of affective relationships and awareness on expertise seeking in groups. Hypotheses were tested using network data collected from 693 employees in 53 sales groups. HLM analysis results indicated that awareness of expertise distribution positively influenced the decision to seek expertise at all levels of analysis examined. In addition, both positive and negative affective relationships influenced expertise seeking, although their pattern of influence differed across different levels of analysis. More specifically, having either a positive or a negative affective relationship with another group member affected the decision to seek expertise from that person. Although having many positive relationships had a positive effect on expertise seeking, having many negative affective relationships had no effect. Moreover, having both an awareness and a positive affective relationship with another group member amplified their positive effect on expertise seeking. Last, individuals who had more negative affective ties were less likely to leverage the positive impact of each awareness relationship on expertise seeking.  相似文献

As societal concern shifts from financial survival towards quality of life issues, both in and outside of the workplace, scholarly interest in employee well-being too has risen greatly in recent years. This greater attention to the antecedents and outcomes of employee well-being, such as job satisfaction, work engagement, and job burnout amongst others, is reflected in the proliferation of theories, constructs, and studies seeking to describe and explain why employees flourish or become exhausted at work, and the effect of employee well-being on individual behaviours and the organization at large. In this article, we provide a selective review of the current state of research in employee well-being, as well as key theories that have been employed in its study, with the aim of providing a critical assessment of the current state of employee well-being research as well as suggest future directions for the field. In particular, we discuss how research adopting intraindividual perspectives in the study of employee well-being can not only add value to our understanding of well-being but also complement the findings from between-individual studies, and offer suggestions for the development of a comprehensive theoretical model that integrates the two perspectives.  相似文献

Adolescence is a period of profound change, which holds substantial developmental milestones, but also unique challenges to the individual. In this opinion paper, we highlight the potential of combining two recently developed behavioural and neural training techniques (cognitive bias modification and functional magnetic neuroimaging‐based neurofeedback) into a research approach that could help make the most of increased levels of plasticity during childhood and adolescence. We discuss how this powerful combination could be used to explore changing brain–behaviour relationships throughout development in the context of emotion processing, a cognitive domain that exhibits continuous development throughout the second decade of life. By targeting both behaviour and brain response, we would also be in an excellent position to define sensible time windows for enhancing plasticity, thereby allowing for targeted intervention approaches that can help improve emotion processing in both typically and atypically developing populations.  相似文献

How would religion and a life event carrying an existential threat (LEET) jointly impact a person's life goals of becoming wealthy and successful in one's career? Goal reprioritisation, socioemotional selectivity, and gerotranscendence theories predict a shift away from material goals following a LEET, independent of the effect of religion. However, terror management theory (TMT) predicts that the effect of death thoughts depends on one's prevailing cultural values. As religion can be regarded as a culture, it is possible that Christians' and non-believers' material life goals would be differentially altered by LEET. Data from 1259 young Chinese adults reveal no main effect of LEET, but a strong effect of religion. Moreover, there was an interaction effect between LEET and religion on material life goals: LEET weakened material goals for Christians but not for non-believers. These findings suggest that TMT is more suitable than the other theories for predicting life goal changes.  相似文献

A wealth of evidence indicates that angiotensin II (Ang II) is involved in learning and memory. However, the precise role of this peptide in these cognitive processes is still controversial, with data indicating either an inhibitory or an enhancing action. The present study was designed to further investigate the effects of intracerebroventricular injections of Ang II (0.5, 1 or 3nmol/5microl) on a step-through passive avoidance task in male adult Wistar rats. When administered pretraining, Ang II did not affect the acquisition of passive avoidance, but markedly improved avoidance performance when given before the retrieval test. The latter effect was observed in retest sessions performed up to 72h after training. Administration of the peptide five minutes after training impaired retention of inhibitory avoidance. Therefore, Ang II may exert opposite effects on passive avoidance memory according to its interference with brain mechanisms leading to the storage or retrieval of this aversively motivated task.  相似文献
