Paths from core belief disruption to post-traumatic stress symptoms and post-traumatic growth among Korean undergraduates: The mediating role of rumination

The post-traumatic growth (PTG) model proposes that cognitive processing is a key mechanism that leads to growth in the aftermath of traumatic events. Building upon the PTG model, the present study examined the paths from the disruption of core beliefs to post-traumatic stress symptoms (PTSS) and PTG via intrusive and deliberate rumination. The sample includes 370 Korean undergraduate students who reported at least one highly stressful experience in their lifetime. Structural equation modeling demonstrated that disruption of core beliefs predicted PTG both directly and indirectly through multiple pathways: via deliberate rumination, intrusive rumination, and the path from intrusive to deliberate rumination. The disruption of core beliefs positively predicted PTSS only through intrusive rumination. No bivariate relationship was found between PTSS and PTG. These findings support the different roles of intrusive rumination and deliberate rumination in mediating the paths from disruption of core beliefs to PTSS and PTG. Implications and limitations of this study were discussed.     

Explaining the Asian American Youth Paradox: Universal Factors versus Asian American Family Process Among Filipino and Korean American Youth

This study used longitudinal survey data of Filipino American and Korean American youth to examine ways in which universal factors (e.g., peer antisocial behaviors and parent–child conflict) and Asian American (AA) family process variables (e.g., gendered norms) independently and collectively predict grade point average (GPA), externalizing, and internalizing problems. We aimed to explain the “Asian American youth paradox” in which low externalizing problems and high GPA coexist with high internalizing problems. We found that universal factors were extensively predictive of youth problems and remained robust when AA family process was accounted for. AA family process also independently explained youth development and, in part, the AA youth paradox. For example, gendered norms increased mental distress. Academic controls did the opposite of what it is intended, that is, had a negative impact on GPA as well as other developmental domains. Family obligation, assessed by family-centered activities and helping out, was beneficial to both externalizing and internalizing youth outcomes. Parental implicit affection, one of the distinct traits of AA parenting, was beneficial, particularly for GPA. This study provided important empirical evidence that can guide cross-cultural parenting and meaningfully inform intervention programs for AA youth.     

Belief in Hell and Parenting Priorities Concerning Child Independence and Obedience: Does Economic Context Matter?

This study examines the ways that belief in hell is associated with parental goals concerning child independence and obedience. Further, it assesses how this association is contingent upon economic circumstances of a nation, reflected by a country's Gross Domestic Product (GDP) per capita. Multilevel analyses with data from the sixth wave of the World Values Survey (2010-2014) show that belief in hell is associated with a greater likelihood of opposing independence and endorsing obedience. Yet, these observed associations differ across national economic context. Specifically, the negative association between belief in hell and parental endorsement of independence is greater in countries that are more economically developed. Similarly, the positive association between belief in hell and parental endorsement of obedience is greater in countries that are more economically developed. The theoretical implications of these findings are discussed regarding the interplay of religion, parental values about child socialization, and social context.     

急性应激损害对威胁刺激的注意解除

急性应激会增强个体对威胁刺激的注意偏向, 但急性应激是增强了对威胁刺激的注意定向还是损害了对威胁刺激的注意解除还不清楚。本研究采用社会评估冷压任务和点探测任务, 结合事件相关电位技术, 考察急性应激对威胁刺激注意偏向影响的认知机制。在进行社会评估冷压任务后, 应激组个体的状态焦虑和皮质醇浓度显著升高。在注意偏向中, 应激组对威胁刺激的注意解除比控制组更慢, 应激组和控制组在对威胁刺激的注意定向上无显著差异。ERP结果上, 威胁刺激诱发应激组比控制组产生了更负的SPCN, 在N2pc上没有显著差异。应激组和控制组皮质醇增量的差异和N2pc、SPCN的组间差异均有显著正相关。这些结果说明, 急性应激增强对威胁刺激的注意偏向是因为其损害个体对威胁刺激的注意解除, 这可能是因为急性应激损害了与注意解除相关的额-顶网络的功能所致。     

直觉和分析在不同信息获取与呈现方式下对多特征目标判断质量的影响

采用多特征目标判断任务,考察了不同信息获取方式与信息呈现方式条件下,直觉和分析思维模式对判断质量的影响。结果发现：（1）在多特征目标判断任务中,直觉思维比分析思维更有效;（2）直觉型决策者运用直觉思维的判断质量比感觉型决策者更高;（3）归类组块的信息呈现方式能够有效提升决策者运用直觉思维的判断质量;（4）思维模式、信息获取方式与信息呈现方式对多特征目标的判断质量存在三阶交互作用,归类组块的信息呈现方式使直觉型决策者运用直觉思维的判断质量最高,而运用分析思维的判断质量低于感觉型决策者;归类组块排列信息时,直觉型决策者运用分析思维的判断质量低于信息随机排列时的水平。     

Work-group characteristics and performance in collectivistic and individualistic cultures

The authors conducted a cross-cultural longitudinal investigation of the effects of culture (individualism-collectivism dichotomy) on group characteristics (functional heterogeneity, preference for teamwork, group potency, outcome expectation) and on performance of 83 work groups performing 2 decision-making tasks over a 15-week period. The individualists (U.S. students) reported higher levels of functional heterogeneity and group potency and attained higher levels of group performance than did the collectivists (Korean students). In addition, culture and time interacted to influence ratings of group potency and outcome expectation. The difference in ratings of group potency between individualists and collectivists increased over time. Outcome expectation was greater among the collectivists in Time 1 and among the individualists in Time 2. The authors discuss implications for future cross-cultural group research and international management.     

Adaptive self-regulation: meeting others' expectations of leadership and performance

The authors used longitudinal multisource field data to examine core aspects of the adaptive self-regulation model (A. S. Tsui & S. J. Ashford, 1994) in terms of linkages between self-monitoring, discrepancy in manager match-to-position, 5 measures of leadership, and manager performance. At Time 1, 64 superiors of focal managers rated the managers' matches to their positions within the organization; at Time 3, they rated the managers' performance. At Time 2, the 64 focal managers completed a measure of self-monitoring, and 192 subordinates rated the focal managers' leadership behaviors. Results of partial least squares analysis revealed that discrepancy in manager match-to-position was associated with reductions in laissez faire and passive management-by-exception behaviors and increases in transformational leadership behavior. Self-monitoring was positively associated with all 5 leadership behaviors. Performance was related positively to transformational leadership behavior and negatively to passive management-by-exception and contingent-reward behaviors
