This study was to assess the moderating roles of intrinsic value in the relation of basic psychological needs support to academic engagement in mathematics. We recruited 246 middle school students by using the Basic Psychological Needs Support Scale, the Intrinsic Value Scale and the Academic Engagement Scale. This study found that both basic psychological needs support and intrinsic value had significant predictions on the three aspects of academic engagement. Moreover, the interaction item between basic psychological needs support and intrinsic value could significantly affect emotional and cognitive engagement, but not behavioural engagement. The findings indicated that except for behavioural engagement, the associations between basic psychological need support and emotional or cognitive engagement could be moderated by intrinsic value. This study provides a special perspective for educators and researchers to recognise the role of intrinsic value in promoting adolescents' higher levels of involvement in mathematics class.  相似文献

We investigated how the ability to deceive emerges in early childhood among a sample of young preschoolers (Mean age = 34.7 months). We did this via a 10‐session microgenetic method that took place over a 10‐day period. In each session, children played a zero‐sum game against an adult to win treats. In the game, children hid the treats and had opportunities (10 trials) to win them by providing deceptive information about their whereabouts to the adult. Although children initially showed little or no ability to deceive, most spontaneously discovered deception and systematically used it to win the game by the tenth day. Both theory of mind and executive function skills were predictive of relatively faster patterns of discovery. These results are the first to provide evidence for the importance of cognitive skills and social experience in the discovery of deception over time in early childhood.  相似文献

Starting in early childhood, children are socialized to be honest. However, they are also expected to avoid telling the truth in sensitive situations if doing so could be seen as inappropriate or impolite. Across two studies (total N = 358), the reasoning of 3- to 5-year-old children in such a scenario was investigated by manipulating whether the information in question would be helpful to the recipient. The studies used a reverse rouge paradigm, in which a confederate with a highly salient red mark on her nose asked children whether she looked okay prior to having her picture taken. In Study 1, children tended to tell the truth only if they were able to observe that the mark was temporary and the confederate did not know it was there. In Study 2, children tended to tell the truth only if they were able to observe that the mark could be concealed with makeup. These findings show that for children as young as age 3, decisions about whether to tell the truth are influenced by the likelihood that the information would be helpful to the recipient.  相似文献

Sleep problems are a significant risk factor for identifying and preventing suicidal involvement among adolescents. However, there is limited evidence to assess the underlying mechanisms between them. This study investigated the longitudinal relationship between sleep problems and suicidal behavior and examined whether this relationship was moderated by negative emotions, low self-control, and nonsuicidal self-injury (NSSI).  相似文献

在非等组铆测验设计中,铆题量占测验长度的多大比例比较合适,这个比例随测验长度的增大可否发生变化?这些是实际工作者和研究者非常关心的问题。该文在固定被试数和测验长度的条件下,探查铆题量所占测验长度比例(简称铆题比例)的变化对等值精度的影响,讨论了在实际等值中如何在等值精度和铆题比例之间取得平衡的问题。并在模拟研究的条件下,给出了几个反应实际等值精度的指标。  相似文献

以群体偏爱的IAT测验为实验材料,结合社会支持和学校适应问卷,考察初中流动儿童在内隐群体偏爱、社会支持上与本地儿童之间的差异,并探讨这两种变量对流动儿童学校适应的影响.结果表明:(1)流动儿童存在内隐外群体偏爱,对自身所属群体表现出内隐的消极认同;本地儿童存在内隐内群体偏爱,对流动儿童具有内隐的消极认知;(2)流动儿童在父亲、教师以及同性朋友的社会支持上显著差于本地儿童;(3)在对流动儿童学校适应的影响上,社会支持的主效应显著,内隐群体偏爱和社会支持的交互作用显著;高内隐群体偏爱组中,高社会支持流动儿童的学校适应优于低社会支持儿童.  相似文献

Effective literacy education in deaf students calls for psycholinguistic research revealing the cognitive and neural mechanisms underlying their written language processing. When learning a written language, deaf students are often instructed to sign out printed text. The present fMRI study was intended to reveal the neural substrates associated with word signing by comparing it with picture signing. Native deaf signers were asked to overtly sign in Chinese Sign Language (CSL) common objects indicated with written words or presented as pictures. Except in left inferior frontal gyrus and inferior parietal lobule where word signing elicited greater activation than picture signing, the two tasks engaged a highly overlapping set of brain regions previously implicated in sign production. The results suggest that word signing in the deaf signers relies on meaning activation from printed visual forms, followed by similar production processes from meaning to signs as in picture signing. The present study also documents the basic brain activation pattern for sign production in CSL and supports the notion of a universal core neural network for sign production across different sign languages.  相似文献

葛洪年表     
葛洪的生平事迹,前人多有稽考,但其扶南之行、庚寅封侯、生卒年以及部分作品的系年等问题,至今分歧较大,仍有深入探讨的必要。文章在前人研究的基础上,重新稽考史料,力求对葛洪的生平进行更为详尽客观的钩稽梳理。  相似文献

本研究采用经典的句尾畸义词诱发N400的ERP实验范式探讨了中国英语学习者在进行英文阅读时语音的影响及其相关脑机制。实验包括两类畸义语句:1.同音畸义:句尾词有畸义,但语音和相应正常语义句尾词相同;2.非同音畸义:句尾词有畸义,且语音和相应正常语义句尾词不同。行为数据显示:在错误率上同音畸义显著地高于非同音畸义。ERP显示:无论在早期(N100)还是晚期(N400)脑电成份上,同音畸义和非同音畸义的ERP振幅都有明显差异。本研究从行为和脑电两个方面一致揭示中国英语学习者阅读英文时受到了语音的影响。  相似文献

葛洪卒年考     
葛洪的年寿及卒年,历来争议较大。通过详细考辨《神仙传》《世说新语》《高僧传》《晋书》《道藏》以及敦煌遗书等所载有关葛洪卒年的各种文献,笔者认为葛洪实卒于晋康帝建元元年(公元343年),享年六十一岁。  相似文献
