记忆面孔,男女有别:关于面孔再认性别差异的行为与ERP研究

采用行为实验及事件相关电位技术,通过学习-测验范式考察面孔再认中的性别差异,结果发现:(ⅰ)女性面孔更容易被记住,且女性很可能比男性更擅长记忆面孔.(ⅱ)旧面孔诱发的N170波幅更大,表明该脑电成分可受到面孔熟悉度的调制.(ⅲ)女性面孔诱发的N170波幅更大,而男性面孔引发的P2波幅更大;前者可能与女性面孔可变化的特征较多、需要更大的心理负载有关;后者可能与男性面孔可变化的特征较少、再认难度较大,从而需要更深的加工有关.(ⅳ)新旧面孔诱发女性被试的P1波幅存在差异,但男性被试身上不存在此现象,提示女性的脑活动可能比男性更早地受面孔的熟悉度所调制.此外,女性被试对于新旧面孔还表现出P2,N250波幅的差异,且女性被试新旧效应涉及的头皮范围比男性更广,这些都为女性较好的面孔再认能力提供了电生理证据.

Emotional Intelligence and Belief in Just World Among Engineering Students

The present study is an attempt to find out relation between emotional intelligence and Belief in Just World （BJW） among engineering students of Pune city. The sample consisted of 217 second year engineering students from various engineering colleges of Pune city. Emotional intelligence was measured with the help of one of the popular measures of emotional intelligence developed by Schutte et al. in 1998 （SE1S）. BJW was measured with the help of General Belief in a Just World scale by Dalbert et al. in 1987. Pearson＇s Product moment correlation was used to find out correlation between BJW and emotional intelligence and test was used to find out gender differences on the variables of the study. Obtained results showed a significant positive correlation between BJW and emotional intelligence. The results demonstrated sex differences in general belief in a just world and also on emotional intelligence. Implications of the study in the light of engineering course have been discussed.

A Study of College Students＇ Autonomous English Listening Ability

Based on the data got from questionnaire in which 75 college students from Heze University participated, the present study aims to explore the current situation of college students＇ autonomous listening ability, its gender difference and the correlation between autonomous listening ability and CET-4 listening achievement. The results indicate that the autonomous listening ability for college students is at the medium level with a great individual difference and there＇s a vast space to be promoted. Moreover, there＇s no significant gender difference in autonomous listening ability for college students and there＇s significant positive correlation between autonomous listening ability and CET-4 Listening achievement, especially the dimension of Application of Strategies. Thus, a conclusion can be drawn that in English listening teaching, teachers should change their teaching model and strengthen the application of network teaching; in English listening learning, English learners should promote their ability of using strategies in English listening in order to improve their autonomous learning ability.

Feminists＇ Culture and Ethics at Work-- A Critical Analysis

The male writers＇ intuitive gift and superb insight describe feminine characters, feminine nature, femaleness, and femininity. In the 19th century, the study of the character logical portrait and cultural traits associated with femininity enunciated feminists＇ discourse to justify vindication of rights as regards women＇s cultural anxiety, political identification, and aesthetic experimentation. Similarly, the women writers＇ imaginative powers characterize women＇s emotions either reflecting shrinking subjectivity or elaborating notion of voluntary subjectivity as regards their experiences and existence, their passions and sensations, and their self and life. The 20th century women＇s writings raised inquiry against presentation of gendered self, performance of gender, gender discontent as regards with their sex and gender, which are assigned at birth as well as also for the alignment of biological sex, sexuality, gender identity, and gender roles. In this paper, the study of the four selected novels such as The Scarlet Letter, Tess of the D ＇Urbervilles, Emma, Surfacing, and Inner Line shows how circumstances, strata of time, and externalities of others objectify woman and her domestic space; how a woman perceives her deprivation as regards her own image which seems nobody to herself due to the sense of low perception; in what way sexual difference and gender-specific practices and ideology enforce woman to chide herself in the given environment and surroundings of legal codifications, moral prescriptions, and medical prognostications. The analyses of the novels draw how woman＇s experience as living subject in the vital dimension of human existence and utopian image of human fellowship is potentially undone by way of sexual exploitation, dismemberment, and embodiment. What kind of vulnerable moments force woman to withdraw from her body and fi＇om her essence is the center of concern in this paper？ While discussing the feminists＇ culture and ethics in their works, the focus is on the essentialized notion of gender-specific discrimination as well as on the frustrating double-consciousness that characterizes the cultural position of the other.

Research on English Majors＇ Willingness to Communicate Inside Classroom

As a new affective variable in the field of L2 （Second Language） Acquisition, the study of WTC （Willingness to Communicate） has attracted widespread attention since the 1990s, which is not only an effective way to promote language learning but also an important language target itself. Based on the data got from the questionnaire, the present study intends to explore the level, gender difference, correlation with academic .performance, and influencing factors of English majors＇ WTC inside classroom using both quantitative and qualitative research method. The results reveal that English majors＇ WTC inside classroom is comparatively high; there is no significant gender difference in English majors＇ WTC inside classroom, and there is significant positive correlation between WTC inside classroom and academic achievement; furthermore, language capacity, language anxiety, and communicative atmosphere are the main influencing factors

独立于铁代谢,雌性对铁超负荷心肌病有保护作用:氧化应激的关键作用

人类和实验动物中存在心脏功能和铁代谢的性别相关差异。男性患者和雄性动物模型更易患心肌病和心力衰竭。然而，在铁超负荷性心肌病中是否存在类似差异并不清楚。方法和结果：雄性和雌性野生型小鼠和铁调素调节蛋白（hemojuvelin）缺陷小鼠分别注射并高铁喂食，以诱导继发性铁超负荷和遗传性血色素沉着症。观察到雌性小鼠被保护免于发生铁超负荷性心肌病，而雄性铁超负荷小鼠发生明显的舒张功能障碍（基于超声心动图和侵入性压力一容积分析）。
