为探究感恩对初中生合作水平的影响,本研究采用追踪调查与实验相结合的方法,通过两个研究分别探究了特质感恩与内在的合作倾向,状态感恩与外在的合作行为之间的关系。结果发现:(1)初中女生的特质感恩、人物取向感恩显著高于男生;初一下的合作倾向显著低于初一上、初二上时期;(2)初中生的特质感恩水平能显著正向预测合作倾向,状态感恩的唤起会增加公共物品困境中的合作行为。  相似文献

多时点结果跨期选择涉及两个及两个以上多个时点结果的权衡, 正日益成为跨期选择的研究重点。现有研究主要从两时点结果和序列结果两方面深入探讨了多时点结果跨期选择中的诸多决策效应, 包括:隐藏的零效应、象征效应、额外金额效应、前端金额效应以及序列效应, 并运用序列模型和权衡模型对上述决策效应进行阐释。未来还应深入探索同时涉及损益结果混合的多时点结果跨期选择, 运用决策过程追踪技术揭示决策效应的过程机制。  相似文献

The student leader system is commonly used in Chinese schools. Student leaders are children who are elected by classmates, then assigned by teachers, to be responsible for monitoring classmates' behaviour. Based on the data collected through an intensive ethnographic study in a rural primary boarding school in China in 2016, this article discusses emotional experiences in peer relationships reported by both student leaders and other ‘ordinary’ students, who were not student leaders. The article argues that China's student leader system is likely to create hierarchical relationships between student leaders and ‘ordinary’ students, and exposes ‘ordinary’ students to the potential risk of being exploited by student leaders. The article also argues that because of this student leader system and relevant student evaluation values, student leaders and ‘ordinary’ students all feel stressed when they are building up and maintaining peer relationships, such as friendships, with each other.  相似文献

This study examined the association between grandparental co-residence and child academic and behavioral outcomes using a sample from Shanghai, China (n = 1,763), and was built on two theoretical perspectives: intergenerational solidarity theory and the contextual model of family stress. These models integrate the impact of residential and relational proximity to grandparents on child well-being and underscore the importance of family context. This study also explored the moderating effects of family resources using proxies that prior theoretical and empirical studies have found to be important to such associations: family income, parental education, hukou status, and subjective social status. Results indicated that among families without co-residing grandparents, rural and low-income parents reported their children to have more externalizing behavioral issues than their respective urban and non-low-income counterparts. In addition, children who resided in poorly resourced families (i.e., low family income, low parental education, low subjective social status, or rural hukou status) tended to benefit from living with grandparents compared to their well-resourced counterparts in terms of lower externalizing and internalizing behaviors reported by teachers. These results do not negate the potential beneficial effects of living with grandparents for children in well-resourced environments. Implications for practice and policy, as well as future research directions, are discussed.  相似文献

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.  相似文献

为探究留守初中生同伴侵害与攻击性的关系机制,通过构建链式多重中介模型,考察歧视知觉、孤独感和心理韧性在二者关系中的多重中介效应。采用问卷调查法对519名留守初中生进行调查,结果显示:(1)留守初中生同伴侵害的发生率为96.3%,具有普遍性;(2)留守初中生同伴侵害、歧视知觉、孤独感、心理韧性与攻击性之间均呈显著相关;(3)留守初中生的歧视知觉、孤独感和心理韧性在其同伴侵害与攻击性的关系中具有链式多重中介作用;(4)同伴侵害与攻击性关系模型具有一定稳定性,同时在是否留守及单亲与双亲外出留守初中生群体中存在显著差异。研究结果揭示了同伴侵害与攻击性的关系机制,可为探索留守初中生不良同伴关系的教育策略提供参考。  相似文献

Community psychology, indeed psychology as a discipline, has been largely absent from the table of school reform. Schools are critical socializing forces in society and serve as the one institution through which the full diversity of our child population passes. At the start of the 21st century, despite successive waves of legislation, the goals of the civil rights struggle for equality in educational opportunity have yet to be achieved. Negative self-fulfilling prophecies, reflected at individual, interpersonal, institutional, and societal levels, play a critical role in creating and perpetuating unequal opportunities to learn. Such effects as well as pathways for preventive intervention are best understood through ecological lenses. Our field must commit a greater share of resources to collaborative and systemic change for a broader learning so that all children, regardless of their differences, have continuing and nonstigmatized opportunities to develop into competent adults.  相似文献

Experiments have shown that human and nonhuman subjects are capable of performing new arbitrary stimulus-stimulus relations without error. When subjects that are experienced with matching-to-sample procedures are presented with a novel sample, a novel comparison, and a familiar comparison, most respond by correctly selecting the novel comparison in the presence of the new sample. This exclusion paradigm was expanded with two California sea lions that had previously formed two 10-member equivalence classes in a matching-to-sample procedure. Rather than being presented with a novel sample on a given trial, the sea lions were presented with a randomly selected familiar member of one class as the sample. One of the comparisons was a randomly selected familiar member of the alternative class, and the other was a novel stimulus. When required to choose which comparison matched the sample, the subjects reliably rejected the familiar comparison, and instead selected the unfamiliar one. Next, the sea lions were presented with transfer problems that could not be solved by exclusion; they immediately grouped the new stimuli into the appropriate classes. These findings show that exclusion procedures can rapidly generate new stimulus relations that can be used to expand stimulus classes.  相似文献
