作为历史唯物主义的重要内容,社会形态思想是对社会历史的形成、发展及其运动的内在规律的深刻揭示和整体阐发,正确把握社会形态思想中的社会历史分期和演进的规律具有十分重要的意义。本文通过对学界关于《政治经济学批判〈序言〉》中社会经济形态演进论述的理解所形成的“三形态说”和“五形态说”争论的梳理和辨析,进一步探讨马克思的社会形态思想,认为马克思在《政治经济学批判〈序言〉》中的相关论述既指出了社会形态演进的基础和发展方向,又隐含着一定社会历史中人的发展状态的内容,同时内蕴分析社会形态的基本原则。  相似文献

以345名12~17岁初中阶段流动儿童为被试,采用问卷法考察学校道德氛围感知在流动儿童父母心理控制与道德推脱关系中的中介作用,以及性别的调节作用。结果表明:(1)父母心理控制正向预测流动儿童道德推脱;(2)学校道德氛围感知在父母心理控制和流动儿童道德推脱之间起到部分中介作用。(3)性别在父母心理控制与学校道德氛围感知间起调节作用,性别调节了中介模型的前半路径,具体而言,与男孩相较,女孩的学校道德氛围感知受到父母心理控制的影响作用更加显著。  相似文献

Multifunctional products are ubiquitous in consumers' daily lives. However, scant research has examined whether and how the presence of multifunctional products systematically alters consumer behavior beyond product evaluations and adoption. Across four experiments and three supplementary studies, the authors identify a multifunction-impatience effect. They show that after exposure to multifunctional (vs. single-function) products, consumers are more likely to choose a smaller but sooner (vs. a larger but later) reward (Study 1), report more impatience when waiting for the web search results to load and perceive the loading time as longer (Study 2), and are willing to pay more for expedited shipping (Study 3). The authors further show that the effects occur because multifunctional products activate an efficiency goal among consumers, which renders them less patient (studies 2 and 3). In addition to the regular, “sequential” multifunctional products for which each of the functions has a specific usage situation, the proposed effect also applies to “simultaneous” multifunctional products whose functions operate simultaneously during consumption (Study 4). Taken together, this research broadens the scholarly understanding of the effects of multifunctional products from consumers' responses to these products to the unintended impact of such products on consumer impatience.  相似文献

随着近几年视频聊天的兴起, 越来越多的研究者开始探索视频聊天对儿童发展的影响。相较于传统通讯技术, 视频聊天具备了视听结合与即时互动的特征; 但同时, 作为数字媒体, 视频聊天仍然保持了传统屏幕媒体二维性的特征。汇总以往视频聊天与儿童学习的实证研究发现, 与录制视频教学比较, 视频聊天在婴幼儿词汇学习(d = 0.33)和动作学习(d = 0.90)上的教学效果更佳; 同时, 视频聊天也能够使婴幼儿在教学过程中保持较高的注意水平(d = 0.90)。视频聊天对儿童远距离亲子关系和同伴关系上均有一定的促进作用。视频聊天也可以作为一种辅助治疗手段应用于特殊儿童的干预中。未来研究仍需关注扩大视频聊天学习中儿童被试的年龄范围、共同观看者的不同支持行为对儿童视频聊天学习的效果产生的影响。  相似文献

为探讨挫折情境下自我肯定对执行功能的影响,创设挫折和非挫折情境,采用价值观自我肯定干预,通过Stroop范式和2-back范式分别测量抑制控制和工作记忆的刷新能力。结果发现,挫折情境下的Stroop任务和2-back任务反应时均高于非挫折情境;挫折情境下自我肯定组在Stroop任务和2-back任务上的反应时均显著低于非自我肯定组,而非挫折情境下两组的反应时没有显著性差异;Stroop效应量在情境与肯定条件上的交互作用不显著。结果表明挫折降低了执行功能的任务表现,自我肯定干预能够改善挫折情境下执行功能相关的任务成绩,促进了个体对工作记忆任务的刷新能力和Stroop任务的认知表现,但对抑制控制能力的改善没有明显作用。  相似文献

The Chinese path to modernization features socialist modernization with Chinese characteristics. It not only adheres to scientific socialism with Chinese characteristics but is also the Chinese road of development during global modernization, the path to realizing the great rejuvenation of the Chinese nation, and the creation of a new model for human advancement. Through the Chinese path to modernization, Chinese civilization with a long history now displays a brand-new form and its unique values and significance on the global stage. This paper probes into the vicissitudes of the Chinese nation in modern times, and reveals the leapfrog development of the great national rejuvenation to highlight the significance of the Chinese modernization by solving the “mystery of figures” ; explores the Chinese nation’s ideological progress during modernization since modern times to show the thought development that Chinese modernization achieved by analyzing the “mystery of thought” ; elaborates on the value orientation of the great national rejuvenation to demonstrate the guidance on values provided by Chinese modernization by explaining the “mystery of values” ; and studies the great rejuvenation of the Chinese nation from a strategic perspective to tap into the rich significance and institutional underpinnings of Chinese modernization by unraveling the “mystery of characteristics.” The Chinese Communists have conducted comprehensive theoretical explorations and pioneered practical innovations in the above aspects, which formed its powerful guidance in ideas and values, the underpinnings of the systematic structures and institutions, and created the Chinese path to modernization. The Chinese path to modernization pushes forward the leapfrog development of the Chinese nation towards modernization, advances the national rejuvenation along the right track, builds a new form of Chinese civilization, and shape the development course of contemporary human culture.  相似文献

In China, rural–urban migration is one of major influences on the mental health of migrant and left-behind children. Literature suggests that the perception of discrimination is an important factor that influences the mental health of these children. The present research explores (1) whether migrant children and left-behind children are different in the relationship between the perception of discrimination and mental health, and (2) whether the relationship between the perception of discrimination and mental health of these children is moderated by gender and age. Using a meta-analytic technique, the authors included 26 studies (generating 48 independent samples) with a total sample size of 28,883 participants. Results showed that the perception of discrimination of migrant children was negatively correlated with positive indicators of mental health, and it has a stronger effect than left-behind children; the perception of discrimination of migrant children was positively correlated with negative indicators of mental health, and it has a weaker effect than left-behind children. Additionally, gender moderated the relationship between the perception of discrimination and the positive indicators of mental health among left-behind children, while age moderated such relationship among migrant children.

Children may be prepared to associate adult disgust reactions with adult disgust elicitors. To test this, three-year olds (and adults) were presented with two images and an emotive vocalization. The images and vocalizations included stimuli adults found disgusting, fear-provoking, and sad. On one set of trials, the main dependent variable (DV) was time spent looking at each image and on a second set of repeat trials the DV was knowledge of image-sound matches. Fear and disgust vocalizations were both more effective at orienting a child's attention to adult fear and disgust images, than sad vocalizations. Parental disgust sensitivity was associated with this effect, moderated by explicit matching knowledge. Matching knowledge was poor in children and good in adults. These data suggest that in children, fear and disgust vocalizations may both promote attention to stimuli that adults find disgusting and/or fear-provoking, suggesting that “preparedness” may not be wholly emotion-specific.  相似文献
