Self-esteem affects individuals in a variety of psychological processes substantially and extensively. While an increase in self-esteem over time was observed in the USA, different patterns of temporal change in self-esteem were observed in other societies. We analysed the responses (n = 305 229) collected between 1993 and 2016 from 609 articles to examine the patterns of temporal change in self-esteem in China and its relations with socioecological conditions. Additionally, we explored the patterns in different groups, including secondary school students (158 samples; n = 97 751), college students (427 samples; n = 153 474), and community participants (232 samples; n = 54 004). Some major findings were noted: (i) overall, the level of self-esteem increased over time. However, we also found a significant curvilinear trend in self-esteem with a decline followed by a recent increase; (ii) some evidence for the relationship between socioecological factors and self-esteem was obtained; and (iii) the patterns varied in different cohort groups. Specifically, secondary school students showed a different pattern, in which their self-esteem level did not show a significant linear trend and was not correlated with the examined socioecological factors. The implications on the theories for the relationship between personality characteristics and socioecological conditions were discussed. 相似文献

Color coding is used to guide attention in computer displays for such critical tasks as baggage screening or air traffic control. It has been shown that a display object attracts more attention if its color is more similar to the color for which one is searching. However, what does similar precisely mean? Can we predict the amount of attention that a display color will receive during a search for a given target color? To tackle this question, two color‐search experiments measuring the selectivity of saccadic eye movements and mapping out its underlying color space were conducted. A variety of mathematical models, predicting saccadic selectivity for given target and display colors, were devised and evaluated. The results suggest that applying a Gaussian function to a weighted Euclidean distance in a slightly modified HSI color space is the best predictor of saccadic selectivity in the chosen paradigm. Hue and intensity information by itself provides a basis for useful predictors, spanning a possibly spherical color space of saccadic selectivity. Although the current models cannot predict saccadic selectivity values for a wide variety of visual search tasks, they reveal some characteristics of color search that are of both theoretical and applied interest, such as for the design of human–computer interfaces. 相似文献

早期应激对抑郁相关行为及神经内分泌反应的长期影响 总被引:12,自引:0,他引:12
临床研究发现,早期创伤性经历是导致成年抑郁症易感性增加的高风险因素之一。但早期应激通过何种途径对抑郁发病产生长期的影响,目前尚不清楚。本文综述了近年来有关的实验动物研究,从早期应激的动物模型建立、早期应激对成年动物抑郁相关行为及神经内分泌反应的长期影响等方面进行了系统论述和分析,进而提出了早期应激并不影响动物的本能行为,但早期应激影响与行为动机和应激应对等认知相关的行为的观点,进一步论证了早期应激是通过增加个体潜在的易患病素质对抑郁症发病产生影响 相似文献

Although creativity has long been recognized as an important aspect of mathematical thinking, both for the advancement of the field and in students' developing expertise in mathematics, assessments of student creativity in that domain have been limited in number and focus. This article presents an assessment developed for creativity that provides a score for mathematical creativity (MaC) in addition to a score for general creativity in the numeric domain, or what we might call numerical creativity (NuC). We developed different rating scales for each and then explored how each scoring method accounts for the students' mathematical/numerical and creative skills. The psychometric properties for both scoring approaches were examined. Each method was shown to reflect different relationships with other performance tests. In addition, it is proposed that MaC may provide useful insight into students' levels of adaptive expertise in mathematics, as reflected by their ability to apply mathematical knowledge (i.e., language, operations, concepts) to novel situations, representing an informative supplement to performance indicators of math achievement. 相似文献

微生态药物包括益生物、益生菌及其复方产品合生素。国外大量临床随机对照试验结果已肯定此类药物用于儿童消化道感染、呼吸道感染等各类感染及 H IV母婴传播等疾病状态中的疗效。微生态药物用于普通婴幼儿群体是安全的,但用于免疫缺陷、患有某些基础疾病、处于临床危象的患儿或早产儿应谨慎。这是由于益生菌为活体,对于其潜在风险如传递细菌耐药、肠道菌群易位及其诱生性感染、诱发乳酸酸中毒和对肠道菌群的长期不良影响等,都需要在临床中仔细体察。本文重点回顾近10年来益生菌、合生素预防和治疗儿童感染性疾病的临床进展。 相似文献

儿童执行功能与情绪调节 总被引:5,自引:1,他引:5
大脑执行功能是一种调节、控制、综合、分析个体心理过程和外显行为的认知神经机制。儿童的高级认知活动、社会性行为(同伴交往、攻击性行为)都受到执行功能发展水平的制约。研究者希望通过儿童执行功能的发展,了解整个执行系统的发展成熟过程,揭示执行控制机能的内在机制。同时,有研究者把执行控制这种认知神经机制和儿童的社会性行为包括自我控制、情绪调控等方面的发展结合起来研究,从中发现二者的联系。该文就这方面的核心问题以及研究成果进行了综述。 相似文献

在网络突发事件的产生和传播中, 人们往往更关注负面信息的加工和传递, 存在负性偏向。本研究依据事件酝酿、爆发、蔓延阶段的特征, 构建心理机制模型, 通过3项研究分别检验了信息内容、信息加工和信息传递中负性偏向的产生和发展。结果表明, 负性偏向不仅产生于网络突发事件的源头语篇中, 还产生于个体信息加工和人际信息传递过程, 表现为个体对负性词汇更好的记忆效果及更高的辨别力, 以及网民间对负性信息的选择性传递和对模糊信息的负性解读。研究有利于认识网络突发事件信息传播规律, 科学应对舆情危机, 创新网络治理。 相似文献

Influence of emotional valence on perceived psychological distance depends on emotional intensity 下载免费PDF全文
Previous findings regarding the relationship between emotional valence and psychological distance were mixed. The current research examined whether emotional intensity moderates the influence of emotional valence on psychological distance. We manipulated intensity and valence by asking participants to describe a positive or negative event from either a high intensity or low intensity perspective. Studies 1 and 2 revealed that negative events were perceived to be more distant than positive events in the low‐intensity condition in two distinct cultural groups. Study 3 further proved that the obtained patterns were generalizable to different emotions. Finally, Study 4 found that a reduced alert level, but not perceived threats, mediated the interactive effects of valence and intensity on psychological distance. This research highlights the importance of considering the joint effect of different dimensions of emotion, thus advancing the understanding of complex processes of emotion. 相似文献
