选取154名3~5岁学前儿童(M=4.11,SD=0.31),采用母亲报告法收集儿童最近3个月最常观看的电视节目、外倾性气质、问题行为和亲社会行为,对19部儿童最常观看的动画片的暴力性进行编码,考察电视暴力频率和暴力残酷性和儿童外倾性对学前儿童社会行为的共同作用。结果:(1)在预测儿童的问题行为时,电视暴力频率与儿童外倾性的交互作用显著,与低外倾性儿童相比,高外倾性儿童观看较多的电视暴力内容会表现出更多的问题行为,观看较少电视暴力内容也会表现出更少的问题行为,支持差别易感性模型;(2)在预测儿童的亲社会行为时,电视暴力频率和暴力残酷性的主效应及其与儿童外倾性的交互作用不显著,外倾性有显著的预测作用,高外倾性儿童表现出更多亲社会行为。  相似文献

基于家庭系统理论与个体-环境交互理论,研究考察了父母情绪表达在父母婚姻质量与儿童内化问题关系中的中介作用,以及儿童迷走神经活动的调节作用。研究选取155名6~7岁小学儿童为被试,运用便携式生理多道记录仪采集儿童静息与任务状态下的心电(ECG)与呼吸率,换算出基线RSA与RSA反应作为迷走神经活动的指标,采用母亲报告的《婚姻质量问卷》、《家庭情绪表达问卷》和《儿童行为量表》测评父母婚姻质量、父母情绪表达及儿童内化问题。结果发现:(1)父母婚姻质量负向预测小学儿童内化问题;(2)父母消极、积极情绪表达在父母婚姻质量与小学儿童内化问题关系中起中介作用;(3)小学儿童迷走神经张力(基线RSA)调节父母消极情绪表达与儿童内化问题关系。研究结果表明父母婚姻质量不仅直接影响儿童内化问题,同时会通过父母情绪表达间接地影响儿童内化问题。另外,较高迷走神经张力能够缓冲父母消极情绪表达对儿童内化问题的影响。  相似文献

New technologies based on artificial agents promise to change the next generation of autonomous systems and therefore our interaction with them. Systems based on artificial agents such as self-driving cars and social robots are examples of this technology that is seeking to improve the quality of people’s life. Cognitive architectures aim to create some of the most challenging artificial agents commonly known as bio-inspired cognitive agents. This type of artificial agent seeks to embody human-like intelligence in order to operate and solve problems in the real world as humans do. Moreover, some cognitive architectures such as Soar, LIDA, ACT-R, and iCub try to be fundamental architectures for the Artificial General Intelligence model of human cognition. Therefore, researchers in the machine ethics field face ethical questions related to what mechanisms an artificial agent must have for making moral decisions in order to ensure that their actions are always ethically right. This paper aims to identify some challenges that researchers need to solve in order to create ethical cognitive architectures. These cognitive architectures are characterized by the capacity to endow artificial agents with appropriate mechanisms to exhibit explicit ethical behavior. Additionally, we offer some reasons to develop ethical cognitive architectures. We hope that this study can be useful to guide future research on ethical cognitive architectures.  相似文献

This paper starts with the social and moral implications of wall in history and in the contemporary world, to usher in the early Confucian discourse on wall and gate. The Confucian discourse implies that walls—either actual, virtual or symbolic—are there to defend and/or to separate, while gates enable the managed access to and opening-up the self-imposed insularity or moderate the self-centred exclusiveness that walls imply. By way of reinterpretation and reconstruction, we will extract from a variety of Confucian discussions the ethical awareness that however strongly built, walls must be associated with gates, and that the wall and the gate are therefore locked in mutuality to make possible the reality of interconnectedness between the inside and the outside and between the self and the other. It will be argued that by using ethical virtues as tools to moderate separation and exclusiveness, Confucian discourses highlight the dynamics of the self-other relationship, and establishes an ethics that may well be still applicable to contemporary situations and can be drawn upon to help dissolve the tension between the values of populist self-centrism and those of globalist interconnectedness.  相似文献

当代中国企业伦理建设是中华人民共和国史的一个重要组成部分。经过革命化、探索与借鉴、培育等阶段,当代中国企业伦理不仅从政治伦理中分离出来,与社会主义市场经济日益相适应,而且企业伦理建设方法也表现出多样化和个性化的趋势。当代中国企业伦理的进步,既有中国经济体制、加入世界贸易组织等制度、环境的牵引,也有市场经济发展过程中企业作为”经济人”的理性选择、买方市场形成等要素的影响。企业伦理道德日益成为企业核心竞争力不可或缺的要素。  相似文献

The goal of this study was to test the response styles theory of depression in a sample of 3rd- and 7th-grade children. In addition, we examined whether the relationship between rumination and increases in depressive symptoms is mediated by hopelessness and low self-esteem. The procedure involved an initial assessment in which depressive symptoms, response styles, hopelessness, and self-esteem were assessed. The procedure also involved a follow-up assessment, 6 weeks later, in which depressive symptoms, hopelessness, and self-esteem were reassessed. Children with a ruminative response style exhibited increases in depressive symptoms over the 6-week period. In addition, the relationship between rumination and increases in depressive symptoms was mediated by both hopelessness and low self-esteem. Last, contrary to our hypotheses, neither distraction nor problem-solving response styles predicted decreases in depressive symptoms over the course of the study.  相似文献

This study, using secondary data analysis, examined prospectively a mediation model of the relationship between acculturation and problem behavior proneness among 330 Hispanic children and adolescents from an urban school district in the southwest region of the United States. Acculturation was predicted to have an indirect, but positive, relationship to problem behavior proneness through parental involvement and self-esteem. The results partially supported the model and indicated that parental involvement, but not self-esteem, played a significant mediational role in children's problem behavior proneness. The individual indicators of problem behavior proneness among Hispanic youth were significantly interrelated, which is consistent with problem behavior theory as conceptualized by R. Jessor (1984) and R. Jessor and S. L. Jessor (1977). Findings from this study provide implications for future research and intervention designs.  相似文献

This paper examines some of the ethical dilemmas that arise when testing for the late onset, untreatable condition of Huntington disease (HD) specifically now that technology allows us to test younger generations of the family for the mutant gene. Drawing on interview data from families with Huntington disease, the reactions to testing and perceived impact on other family members are considered. These are discussed in the light of the possible lowering of the age of test applicants. This potentially raises problems for a younger generation as they are confronted with reproductive decisions that the older generation did not have to face. It also means that individuals have the prospect of living with knowledge of a future illness for much longer.  相似文献
