听写障碍儿童的字形输出错误特点

阅读正常而听写落后的听写障碍是一种特殊的学习障碍类型,相关研究非常缺乏.本研究首先根据听写错误分类,考察了听写障碍儿童在认读正确的听写错误中,各种错误类型分布特点.发现,(1)对于所有被试来说,零反应都是一种主要的错误形态;(2)听写障碍被试的零反应比例明显高于总体平均成绩.为了进一步考察障碍组较高零反应的原因,本研究考察了字形提示对听写成绩的影响.结果,(3)障碍组被试的提示有效率明显高于对照组.这表明,听写障碍儿童形音表征联结的缺陷可能是导致大量的零反应的主要原因.     

客观认识心脏介入治疗

心脏介入治疗技术作为当代心血管领域里先进技术的代表,已在我国很多医院广泛应用,取得了良好的疗效.然而,近年来由于医疗卫生体制的不完善,导致某些医务人员对它的认识出现了偏差,甚至滥用心脏介入治疗技术,给国家和患者带来沉重的负担.因此笔者认为有必要客观认识它,规范它在临床上的应用,使其真正做到为患者解除疾苦.     

我国非瓣膜病房颤抗凝的现状与思考

心房纤颤增加缺血性脑中风4倍～5倍,抗凝治疗可减少60%的缺血性脑中风,但是同时会增加出血的风险,尤其是脑出血.我国是脑中风,特别是出血性脑中风的高发国家,所以对于房颤抗凝的临床决策往往偏保守,造成我国房颤患者抗凝比例很低.本文就如何在我国房颤患者中进行抗凝提出意见.     

自恋与自尊：社会赞许性的中介作用

目的：考察社会赞许性在自恋与自尊关系中所起的中介作用。方法：对614名大学生进行自恋人格问卷（NPI）、自尊问卷（SES）、马洛一克罗恩社会赞许量表（MCSD）测评。结果：高自恋者的自尊水平显著高于低自恋者;自恋总分及权欲、优越感、自我钦羡三个因子与自尊显著性正相关,特权感因子与自尊负相关;自恋总分及权欲、优越感、自我钦羡因子对自尊有较好的直接预测效应,以社会赞许性为中介能更好地解释特权感因子与自尊的关系。结论：自恋与自尊关系稳定,自恋的权欲、优越感、自我钦羡因子预测健康的自尊,特权感因子预测防御性的自尊。     

The My Emotions Questionnaire: A self-report of mothers’ emotional responses to infant crying

The purpose of this article was to examine the psychometrics of the My Emotions Questionnaire, a self-report designed to assess mothers’ emotional reactions when their infants cry. Participants were 240 first-time mothers. When infants were 6 months and 1 year old, mothers completed the new questionnaire and measures assessing beliefs and behavioral responses to infant crying, and interview-based measures of mothers’ emotional reactions and causal attributions about crying were administered. Maternal sensitivity and negative behaviors were observed when infants were 6 months and 1 and 2 years old. Mothers reported on their discipline practices when children were 2 years old. Five emotion factors emerged based on exploratory factor analysis (EFA) of the 6-month data: Amusement, Anxiety, Frustration, Sympathy, and Protective. The five-factor structure was supported via a confirmatory factor analysis (CFA) of the 1-year data. All scales demonstrated adequate internal consistency reliability and significant stability from 6 months to 1 year. Amusement, Frustration, and Protectiveness demonstrated the best convergent validity with cry cognitions and predictive validity to parenting measures, followed by Anxiety, although effects tended to be small to moderate. Evidence for the validity of Sympathy was less compelling. The potential utility of the questionnaire for basic and applied research is discussed.     

周代士婚礼对中国古代王室婚礼的影响

中国传统婚礼礼仪来源于儒家礼学经典著作《仪礼·士昏礼》中所反映的周代婚姻六礼,但这些礼仪是怎样影响中国古代的王室婚礼,时至今日没有任何学者对此作过全面系统的解释并得出令人信服的结论。文章运用比较研究的方法,从议婚到结婚过程中的文辞话语和仪式要素两个方面,全面深入地比较了周代士婚礼与秦汉以后部分朝代王室婚礼的共同性和差异性。就此认为,中国古代以汉族为主的历代王室婚礼的基本范式均来自于周代的士婚礼,以其他民族为主建立政权而形成的王室婚礼则具有各自的区域民族特色,从而使得中国古代的王室婚礼在总体上形成了一种具有二元结构的仪式象征符号体系。     

From Glossy to Greasy: The Impact of Learned Associations on Perceptions of Food Healthfulness

We demonstrate that consumers have learned that unhealthy snacks such as potato chips tend to be sold in glossy packages, whereas healthier snacks such as crackers tend to be sold in matte packages (in studies 1–3). As a result, consumers who see a snack food package with a glossy [matte] surface will infer lesser [greater] healthfulness of its contents (study 4), consume less [more] of it (study 5), and be more likely to choose a glossy [matte] package from an assortment of snack packages if motivated to engage in tasty [healthful] eating (study 6). Theoretical and managerial implications as well as future research opportunities are discussed.     

Delayed response, preoperative overtraining, and prefrontal lesions in the rat

An earlier study in this laboratory found that preoperative overtraining improved retention of a delayed alternation task after prefrontal lesions in the rat. In this study, however, it was found that preoperative overtraining did not improve performance of the rat in a delayed response task following prefrontal lesions. These results support the hypothesis that preoperative overtraining can improve postoperative performance only when postoperative recovery is ordinarily present, as it is with delayed alternation. but not with delayed response, in the prefrontal rat. This suggests that effects of preoperative overtraining and postoperative recovery may be mediated by similar mechanisms. It further suggests that a shift of function, which seems to account for postoperative recovery, may occur in some parts of the normal adult brain as a result of overtraining.

催产素调控心理韧性:基于对海马的作用机制

心理韧性指个体面对逆境、挫折或重大威胁等应激情境下的有效且灵活适应的能力, 促进机体恢复正常的生理和心理功能。研究表明海马是调控心理韧性的重要脑区, 且催产素可能通过作用于海马增强心理韧性。海马内部环路内嗅皮层-齿状回-CA3可能调节恐惧记忆的泛化和消退以增强心理韧性; 海马外部环路齿状回-杏仁核-伏隔核及海马-伏隔核环路调节情绪, 可能分别通过促进奖赏和带来厌恶进而增强或降低心理韧性。催产素作用于海马增强心理韧性的可能途径有:催产素促进海马神经发生, 降低海马腹侧成熟神经元对应激的敏感性, 提高海马“模式分离”功能, 降低应激记忆泛化; 催产素恢复海马谢弗侧枝-CA1突触长时程增强, 促进机体适应应激; 催产素降低海马糖皮质激素受体水平, 重新建立机体稳态。
