学业不良学生类型与特点的聚类分析   总被引:9,自引:0,他引:9  
该研究运用Q聚类分析对上海市区1480名初中预备班学生的能力和个性特征进行分类研究。结果发现1480名被试中存有心理发展水平不同的六个主要类别,这些类别与学生学业成绩的优劣关系密切。同时,353名差生可分为四个主要类型:即,暂时性困难学生、能力型困难学生、动力型困难学生和整体性困难学生,不同类型的差生具有不同的特点。这为针对不同类型学生的特点制定有效的教育措施提供了依据。  相似文献

铁路色灯信号不论在白天或夜间都指挥着列车的运行,其显示好坏直接关系到列车的安全和效率。影响色灯信号显示的因素很多,如光源参数,光系统结构,灯光散角,天气好坏等。而色灯信号的颜色,观察距离(或视张角)以及亮对比度是人对信号识别的三个较重要因素,所以我们想从这三个方面来讨论信号灯光显示问题。  相似文献

Following the release of the first COVID-19 vaccinations many people utilized social media to promote vaccination among their social circles. These attempts to persuade others to get vaccinated ranged from positive encouragement (e.g., emphasizing the prosocial benefits and positive outcomes) to shame and threats (e.g., name calling and threating to end friendships over vaccination status). The present study investigated how these different social media messages affected COVID-19 vaccination intentions. In June 2021, shortly after vaccines had been made freely available to anyone over the age of 16 in the United States, unvaccinated participants read a manipulated Twitter message designed to be either encouraging or shaming. Message-type did not significantly affect intentions to become vaccinated against COVID-19; however, participants who saw the encouraging message reported that the post made them feel more likely to get vaccinated. Self-efficacy was also manipulated but did not reveal any significant effects. Additional analyses suggest that having personal experience with COVID-19 moderates reactions to these different messages. We discuss limitations and promising avenues for future research on the effects of social media messages on health behaviors.  相似文献

要讲清无神论与道德问题,首先要讲清宗教与 道德问题。我们就从宗教与道德讲起。 第一部分:实践部分 一、布什到清华大学演讲,鼓励学生们信宗 教,说信了宗教,道德就高尚。 二、宗教界有不少人说,信了教,道德就高 尚。不信教,无法无天,无恶不作。 三、宗教研究的学者,也有不少人说,信了教 道德就高尚。并且援引某些资料说,某某地区信教 的多,犯罪率就低。某某人信了教,改掉了过去的 毛病。  相似文献

Underpinned by the stimulus–organism–response model, this study explores the underlying mechanism through which green advertising skepticism on social media affects consumer green purchase intention. It also investigates the boundary factors that moderate this indirect relationship. Performing structural equation modeling on data collected from an online survey on Sina Weibo, this study finds that green advertising skepticism on social media negatively affects green purchase intention through the mediation of perceived information utility. Moreover, interdependent self‐construal positively moderates, and independent self‐construal negatively moderates this indirect relationship. These findings suggest that truthful and consumer‐tailored green advertising is crucial to green product marketing.  相似文献

This experiment investigated effects of report order and training on multidimensional stimulus identification. Subjects were required to identify each two-dimensional symbol. There were two orders of reporting the two dimensions of a stimulus. Subjects performed the task for three practice sessions. Both behavioral data and event-related potentials were recorded. Analysis showed order of report had no significant effect on behavior data. But when participants responded in Order Shape/ Part, they showed more N2 inhibition for Order Part/Shape. The P3 mean amplitude was marginally significantly greater for Order Part/Shape than Order Shape/Part. This indicated Order Part/Shape, according to natural language habits, was more appropriate and less cognitively demanding than Order Shape/Part. For the two report orders, along with reduction of reaction time, amplitude of N1 and N2 increased with practice. Amplitude of P2 decreased with practice, and no P3 habituation was found. ERP data indicated no habituation effect. Results suggested neural activity depended not only on perceptual mechanism but also on extent of learning.  相似文献

A number of studies have supported the hypothesis that negative attributional styles may confer vulnerability to the development of depression. The goal of this study was to explore factors that may contribute to the development of negative attributional styles in children. As hypothesized, elevated levels of depressive symptoms and hopelessness at the initial assessment predicted negative changes in children's attributional styles over the 6-month follow-up period. In addition, elevated levels of verbal victimization occurring between the 2 assessments, as well as that occurring in the 6 months preceding the initial assessment, prospectively predicted negative changes in children's attributional styles over the follow-up. Further, initial depressive symptoms and verbal victimization during the follow-up continued to significantly predict attributional style change even when the overlap among the predictors was statistically controlled. Contrary to the hypotheses, however, neither parent-reported levels of overall negative life events nor parents' attributions for their children's events predicted changes in children's attributional styles.  相似文献

新课程背景下上海市中小学教师职业角色认同的研究   总被引:4,自引:0,他引:4  
沈之菲 《心理科学》2005,28(3):723-726
本研究是在了解新课程背景所倡导的教师角色的基础上,对教师职业角色认同状况的调查和分析。结果发现:教师在职业角色认同上可以分两个组:“高认同组”和“一般认同组”。在调查的十个教师职业角色中,“教师是文化的传播者”;“教师是学生学习能力的培养者”;“教师是学生人生的引路人”处于角色认同排序的前三位,“教师是专家”、“教师是教育家”、“教师是社区型的开放的教师”处于排序的后三位,其余“教师是教育教学的研究者”;“教师是学生的心理顾问”;“教师是课程的建设者和开发者”和“教师是学者”居中。教师所处的学校类型、教师性别和是否担任行政职务,在职业角色认同上有非常显著和显著的差异。小学教师的职业角色认同要高于初中教师,初中教师又高于高中教师。女教师的职业角色认同要高于男教师。学校行政领导的职业角色认同要高于普通教师。  相似文献

脑科学研究发现,简单心算主要涉及算术事实的提取,依赖于左半球的语言中枢,而复杂心算激活了左侧顶—额叶网络和双侧颞下回,与视觉空间表征和视觉表象加工有关;精算主要激活左额叶下部区域,而估算激活了两半球更大的区域。在计算过程中所激活的脑区受年龄发展与个体差异以及训练的影响。研究对有效地促进儿童计算能力的发展提供了重要启示。  相似文献

现象的本质   总被引:1,自引:0,他引:1  
沈顺福 《现代哲学》2007,45(4):80-86
物、现象是主体运用自己的先验感知模式整理纯粹本体的结果。它具有现实确定性、质量性、合理性、时间性、空间性、生灭性、特殊性、有用、有利等属性。拥有这些属性的现象是人类知识的对象。现象是相对的,因此它的这些属性也都是相对的。同时,存在不仅仅有生生不息的纯粹本体,而且它的必然伴随物即现象也是存在的真谛。现象与纯粹本体一起共同构成存在的事实本体。纯粹本体、现象的分与合即一三三一圆融构成了存在的综合本体。纯粹本体论、事实本体论和综合本体论构成了中国古代形而上学史上三个不同的发展阶段。  相似文献
