Gender differences in children's arithmetic performance are accounted for by gender differences in language abilities

Studies have shown that female children, on average, consistently outperform male children in arithmetic. In the research reported here, 1,556 pupils (8 to 11 years of age) from urban and rural regions in the greater Beijing area completed 10 cognitive tasks. Results showed that girls outperformed boys in arithmetic tasks (i.e., simple subtraction, complex multiplication), as well as in numerosity-comparison, number-comparison, number-series-completion, choice reaction time, and word-rhyming tasks. Boys outperformed girls in a mental rotation task. Controlling for scores on the word-rhyming task eliminated gender differences in arithmetic, whereas controlling for scores on numerical-processing tasks (number comparison, numerosity estimation, numerosity comparison, and number-series completion) and general cognitive tasks (choice reaction time, Raven's Progressive Matrices, and mental rotation) did not. These results suggest that girls' advantage in arithmetic is likely due to their advantage in language processing.     

孙中山与中国近代医学

孙中山是中国革命伟大的先行者,他早年接受西医教育,从事医生职业,弃医从政后,又致力于医疗卫生管理事业的发展.先生所处的时代与接受的西医教育、济世救人的行医生涯中所体现出的医术与医德、坚持中西医结合的远见卓识以及对医疗卫生事业的创新发展都与中国近代医学有着不可分割的联系.     

基于内科查房会话语料的医生礼貌策略分析

采用录音方式收集50例内科查房语料,用Brown和Levinson的面子理论分析了医患会话中医生的礼貌策略,发现医生使用的积极礼貌策略类型有反馈、称谓、关照和赞誉等,消极礼貌策略主要有弱化、主动两类,且消极礼貌策略使用频率高于积极礼貌策略.分析显示现阶段平等的医患关系尚未完全建立.     

竹简《文子》天道论初探

＂天道＂是中国思想史上的重要概念。在竹简《文子》中,天道不仅是对于世界万物起源的认识,也是对社会发展规律性的认识,它具有自然和社会双重属性。竹简《文子》的天道论继承了老子＂道生于有＂的思想,但否认＂有生于无＂,＂有＂是其终极。人的行为必须遵循天道。竹简《文子》中对于＂天道＂自然属性和社会属性的阐释,也为后世很多思想家所继承。     

浅谈如何提高医疗活动中药师的服务质量与技术水平

药师工作是集业务、技术及服务于一体的综合性工作,是患者在整个医疗诊治过程中的一个非常重要的环节,其服务质量的好坏对患者的治疗效果以及药剂科的形象有着重要的影响.减少医患纠纷、改善患者的就医环境以及治疗质量,要求药师在医疗活动中不断提高自身的服务质量与技术水平.     

潜在锚定效应的加工机制初探

潜在锚定效应指的是阈限下的启动锚定数字导致的锚定效应现象.本研究探讨了潜在锚定效应的产生机制.采用2(潜在锚类型:高锚vs低锚)×2(词汇类型:夏天vs冬天)混合设计.结果发现,在潜在高锚情况下,夏天词汇的反应时(M=745.50)显著快于冬天词汇的反应时;在潜在低锚情况下,冬天词汇的反应时(M=697.47)显著快于夏天词汇的反应时.即被试对与启动锚定数字信息一致的词汇判断的反应时比不一致的更快.研究结果表明,潜在锚定效应的产生是由于锚定数字内部命题属性被激活导致的.     

Cold-blooded loneliness: social exclusion leads to lower skin temperatures

Being ostracized or excluded, even briefly and by strangers, is painful and threatens fundamental needs. Recent work by Zhong and Leonardelli (2008) found that excluded individuals perceive the room as cooler and that they desire warmer drinks. A perspective that many rely on in embodiment is the theoretical idea that people use metaphorical associations to understand social exclusion (see Landau, Meier, & Keefer, 2010). We suggest that people feel colder because they are colder. The results strongly support the idea that more complex metaphorical understandings of social relations are scaffolded onto literal changes in bodily temperature: Being excluded in an online ball tossing game leads to lower finger temperatures (Study 1), while the negative affect typically experienced after such social exclusion is alleviated after holding a cup of warm tea (Study 2). The authors discuss further implications for the interaction between body and social relations specifically, and for basic and cognitive systems in general.     

Ethnic and mainstream social connectedness, perceived racial discrimination, and posttraumatic stress symptoms

Carter (2007) proposed the notion of race-based traumatic stress and argued that experiences of racial discrimination can be viewed as a type of trauma. In a sample of 383 Chinese international students at 2 predominantly White midwestern universities, the present results supported this notion and found that perceived racial discrimination predicted posttraumatic stress symptoms over and above perceived general stress. Furthermore, Berry (1997) proposed an acculturation framework and recommended that researchers advance the literature by examining the moderation effects on the association between racial discrimination and outcomes. The present results supported the moderation effect for Ethnic SC (i.e., social connectedness in the ethnic community), but not for Mainstream SC (i.e., social connectedness in mainstream society). A simple effects analysis indicated that a high Ethnic SC weakened the strength of the association between perceived racial discrimination and posttraumatic stress symptoms more than a low Ethnic SC. Moreover, although Mainstream SC failed to be a moderator, Mainstream SC was significantly associated with less perceived general stress, less perceived racial discrimination, and less posttraumatic stress symptoms.     

The Concerns about Counseling Racial Minority Clients scale

The purpose of this study was to develop and validate the Concerns about Counseling Racial Minority Clients (CCRMC) scale among counselor trainees. Sample 1 was used for an exploratory factor analysis and confirmatory factor analysis. Four factors were identified, Managing Cultural Differences (α = .82), Offending or Hurting Clients (α = .87), Biased Thoughts and Behaviors (α = .81), and Client Perceptions (α = .77). The coefficient alpha for the CCRMC was .90. The results support the validity of the scale. The scores on the CCRMC and its subscales have positive associations with fear of negative evaluation from others (r = .19 to .40) and negative associations with general counseling self-efficacy (r = -.30 to -.46) and multicultural intervention self-efficacy (r = -.30 to -.64). The CCRMC significantly predicted fear of negative evaluation, session management self-efficacy, and multicultural intervention self-efficacy over and above multicultural social desirability. The validity evidence was not different between White and minority graduate trainees. In Sample 2, the estimated 1-week test-retest reliabilities ranged from .75 to .96 for the CCRMC and its four subscales.
