"济世"是丘处机一生的主要人格特征,它包含三方面内容:积功累德,自善其身;拯世济民,兼善天下;悲天悯物,兼济苍生.丘处机之"济世"根源于人之"善心",仁爱慈善、珍爱一切生命是它的精神内核.丘处机"济世"人格的形成是其立足道教,吸纳儒家思想的结果,包蕴着深刻而丰富的人文内涵,体现出全真道以善求真、以善合真、真善结合的审美追求.本文试图从对丘处机"济世"人格的剖析中,探求全真道的宗教美学思想. 相似文献

720名中学生自我同一性地位研究 总被引:9,自引:0,他引:9
对中学生自我同一性实证研究表明,中学生自我同一性发展经由一个理慰朦胧——困惑疑为——现实提升的过程。中学生自我同一性地位度数分布中间大,两头小。中学生自我同一性地位存在性别差异。中学生自我同一性地位与学习成效自评交互影响。对中学生自我同一性教育训练应予以重视和加强。 相似文献

An adult-like concept of intention includes a deliberate action to achieve a goal and a belief that one's action (if successful) will cause the desired outcome. For example, good outcomes caused by accident or by chance are not believed to be caused intentionally. In two experiments, we asked whether children understand this connection between intentions and outcomes. Children played two games in which actions could produce unintended outcomes (i.e., causes were unplanned). Children sometimes received a desirable reward independent of intention. In Experiment 1, 4- and 5-year-olds mistakenly claimed they had intended the desirable outcome even when it was unexpected. Four-year-olds judged that they had not intended a deliberate action if it did not yield a rewarding outcome. Experiment 2 demonstrates that 6-year-olds seldom make these errors. The results suggest that 4- and 5-year-old children have not yet attained an adult-like concept of intention. Their inaccurate judgments regarding their intentions, given a rewarding yet unexpected outcome, can be explained by a positivity bias. 相似文献

该研究以某985高校550名硕士毕业生为样本,编制、修订了相关问卷或量表,通过数据分析探讨了就业压力源对就业过程产生的负性情绪的直接效应及人格、情绪调解策略等中介变量的效应。结果发现,就业压力源、神经质性对负性情绪有显著直接效应,就业压力源通过人格的神经质性维度对负性情绪产生显著间接效应;神经质性的影响程度大于就业压力源的影响程度。关于负性情绪,未发现情绪调节策略对其有显著的直接效应或中介效应。 相似文献

采用长时重复启动范式进一步探讨言语理解中信息表征的方式.实验1探讨听力理解中的信息表征,学习阶段采用句子理解任务,测验阶段进行图片判断任务,结果发现匹配和不匹配的图片的反应时和正确率没有显著差异,学过和未学过的图片的反应时和正确率也没有显著差异,说明听力理解中的信息表征是命题符号表征,而非知觉符号表征.实验2探讨阅读理解中的信息表征,结果同实验1,说明阅读理解中的信息表征也是命题符号表征,而非知觉符号表征.实验3在学习阶段和测验阶段都采用句子理解任务,结果发现学过的句子的反应时快于未学过的句子的反应时,学过的句子的正确率高于未学过的句子的正确率,说明前两个实验中没有出现学习效应是因为两个阶段任务类型差异较大造成的.综合3个实验的结果,可以初步得出结论,排除策略影响后,言语理解中没有产生知觉符号表征,先前句图匹配范式下的知觉符号表征很可能是一种策略性的表征. 相似文献

The kynurenine (KYN) pathway, which is initiated by indoleamine 2,3-dioxygenase, is the main tryptophan (TRP) metabolic pathway. It shares TRP with the serotonin (5-HT) pathway. We investigated the influence of inescapable-predator (rat) stress on behavior and brain TRP metabolism in mice. Male ICR mice (4W) were exposed to 20-min inescapable-predator stress. Behavior on an elevated plus-maze, and TRP, KYN, and 5-HT levels in the prefrontal cortex, hippocampus, amygdala, and dorsal raphe nuclei were measured 1 and 4 weeks after stress exposure. Predator stress increased the number of open-arm entries (NOA) 4 weeks after stress exposure without altering the number of closed-arm entries (NCA). Thus, the open/closed-arm entry ratio (NOA/NCA) increased after stress exposure. Predator stress increased KYN levels in the prefrontal cortex (until 4 weeks after stress exposure) and dorsal raphe nuclei (for 1 week after stress exposure), decreased 5-HT levels in all brain regions (until 4 weeks after stress exposure). Thus, predator stress increased the KYN/5-HT ratio in all regions, in particular in the prefrontal cortex and hippocampus until 4 weeks after stress exposure. Predator stress shifted the balance between the KYN and 5-HT pathways to the KYN pathway, and induced behavioral disinhibition. 相似文献

Self-regulatory behavior in early childhood is an important characteristic that has considerable implications for the development of adaptive and maladaptive functioning. The present study investigated the relations between a functional polymorphism in the upstream region of monoamine oxidase A gene (MAOA) and self-regulatory behavior in a sample of Chinese infants at 6 months of age. Self-regulation was assessed by observing infants' behavior of orienting visual attention away from a threatening event in the laboratory situation. The results indicated that regulatory behavior was associated with the functional MAOA gene polymorphism in girls, but not boys. Girls with 4/4 genotypes displayed significantly higher regulation than girls with 3/3 and 3/4 genotypes. The present study provided evidence for gender differences on the role of MAOA gene polymorphism in socioemotional functioning in the early years. 相似文献
