视觉工作记忆对自上而下注意控制的影响:发展视角的探讨

注意控制探讨个体以何种方式选择性地注意外界信息。本研究从发展角度探讨视觉工作记忆对自上而下注意控制的影响。研究采用记忆任务与视觉搜索任务相结合的范式,以小学三、四、五年级学生为被试,从视觉工作记忆中信息性质和视觉工作记忆负荷两个角度考察了视觉工作记忆对自上而下注意控制影响的发展特点。结果发现,(1)自上而下注意控制能力存在年级差异,小学五年级学生的成绩显著优于小学三年级学生;(2)视觉工作记忆内容影响自上而下注意控制,目标相关信息促进目标搜索,而目标无关信息干扰目标搜索;(3)视觉工作记忆负荷影响自上而下注意控制,高视觉工作记忆负荷条件下的反应时显著长于低视觉工作记忆负荷。     

中学生学习成功感量表的初步研究

在访谈、开放式问卷等的基础上,自编了中学生学习成功感量表,并对上海市随机抽取的642名中学生进行了测量。结果表明：该量表的49个项目均有较好的区分度;四个分量表之间的相关表明该量表的建构是正确的;因素分析表明成功感分量表可以分为：与学习本身有关的积极情感、与他人有关的积极情感、满意感和学业自我效能感四个因子;该量表有较高的信度和效度,可以作为评鉴中学生学习成功感的有效工具。

传统本体论哲学的终结和马克思哲学变革的实质

本文从讨论Ontology的译名开始,主张严格区分作为一门哲学分支学科的“存在论”,和作为一种特定哲学理论形态的“本体论”两个概念;通过对传统西方哲学所代表和象征的哲学理念的把握,揭示了其基本特征和历史命运;进而从马克思哲学与传统西方哲学的否定性关系视角,阐明了马克思哲学变革的实质和意义。作者认为,马克思哲学在哲学史上最具深远意义的革命变革,就在于它通过对传统本体论哲学的批判和超越,开创了哲学发展的新方向．奠定了哲学发展新形态的基础。     

Eye movements and the perceptual span in silent and oral reading

Previous research has examined parafoveal processing during silent reading, but little is known about the role of these processes in oral reading. Given that masking parafoveal information slows down silent reading, we asked whether a similar effect also occurs in oral reading. To investigate the role of parafoveal processing in silent and oral reading, we manipulated the parafoveal information available to readers by changing the size of a gaze-contingent moving window. Participants read silently and orally in a one-word window and a three-word window condition as we monitored their eye movements. The lack of parafoveal information slowed reading speed in both oral and silent reading. However, the effects of parafoveal information were larger in silent reading than in oral reading, because of different effects of preview information on both when the eyes move and how often. Parafoveal information benefitted silent reading for faster readers more than for slower readers.     

面孔部件相似性判断研究

用Morph变形方法构建家族相似性面孔部件样例,采用多级估量法探讨分类活动中面孔部件相似性判断问题。结果发现,部件样例对部件原型的隶属度及部件样例对整体原型中对应部件的隶属度与部件样例变形百分比间是3次函数关系;耳朵、脸型、眼睛等部件样例对整体原型中对应部件的隶属度小于其对部件原型的隶属度,嘴巴样例对整体原型中嘴巴部件的隶属度高于其对部件原型的隶属度。表明面孔部件物理相似性与心理相似性间是3次函数关系;整体原型中其他部件降低了耳朵、脸型、眼睛等部件样例对整体原型中对应部件的隶属度,而提高了嘴巴样例对整体原     

Cognitive and Personality Characteristics of Masculinity and Femininity Predict Wayfinding Competence and Strategies of Men and Women

Bem (1974) reconceptualized masculinity and femininity as independent and orthogonal constructs that both men and women possess to varying degrees. This perspective was used as a starting point to investigate whether the contributions of gender-typed characteristics can help to account for commonly observed gender differences in wayfinding (the ability to identify one’s current location and successfully navigate to an unseen location in the environment) favoring men. We further divided gender-typed characteristics into cognitive and personality characteristics to assess their separate influence on wayfinding and explored whether gender-typed characteristics predicted self-reported use of masculine wayfinding strategies (i.e., orientation strategies) and self-reported wayfinding competence. Participants were 452 college women and men in a southern U.S. public university. They completed the Gender-Stereotypic Characteristics questionnaire (Diekman and Eagly 2000), a social comparison questionnaire (created by the authors), a wayfinding strategy questionnaire (Lawton 1994), and a wayfinding competence questionnaire (Hegarty et al. 2002). For both men and women, higher masculine cognitive characteristics significantly correlated with greater use of orientation wayfinding strategies typical of men. For men, both higher masculine and feminine cognitive characteristics predicted better overall wayfinding competence whereas for women, only higher masculine cognitive characteristics predicted better overall wayfinding competence. For both men and women, higher feminine personality characteristics predicted poorer wayfinding competence. These results demonstrated the importance of considering cognitive and personality characteristics of masculinity and femininity in explaining individual differences in wayfinding.     

Crossover of Weekly Work Engagement Among Dual-Working Couples

Purpose

Based on crossover theory and the actor-partner interdependence model, the purpose of this study was to investigate the crossover process of work engagement among Chinese dual-working couples.

Design/Methodology/Approach

Fifty-one dual-working couples first completed a general questionnaire to collect basic demographic information and then completed a weekly diary over five consecutive work weeks.

Findings

The results of multilevel analyses showed that (1) actor’s work engagement had a significant impact on his or her own work performance, (2) communication quality between the dual-working couples moderated the crossover of work engagement, but this effect was only found from husbands to wives and when women scored high on communication quality, (3) when men were treated as actors, the actor’s work engagement interacted with communication quality to relate to the partner’s work performance, through the mediating mechanism of the partner’s work engagement.

Implications

Dual-working couples should communicate with each other frequently through sharing positive experiences, and each member of the couple should support the partner through concrete actions. Organizations should adequately facilitate employees’ engagement, as engaged employees can not only positively influence their colleagues but also their partners at home.

Originality/Value

Previous research on work engagement has focused mainly on static and cross-sectional studies, and most studies on crossover have been conducted primarily in the context of western cultures, whereas systematic and empirical study of oriental cultures, especially Chinese cultures, is relatively scarce. The current study explored the crossover process of work engagement among Chinese dual-working couples using a diary study methodology.

     

证券资本及其二重性分析

证券资本是指证券法所调整的各类社会关系中参与直接投/融资活动之货币运动的总和,货币是证券资本的主要表现形式。无论是资本形态还是资本规模,证券资本均与公司资本存在重大差别,公司资本仅是证券资本之发行资本的一部分。以证券法所调整的社会关系分析,证券资本二重性最直观的表现是发行资本和交易资本,而其本质是实体资本和虚拟资本;广义地看,证券资本二重性又表现为境内资本和境外资本、自有资本和非自有资本、长期资本和短期资本。证券资本及其二重性是证券立法中若干二元结构性问题的基础。     

非酒精性脂肪肝的治疗策略

非酒精性脂肪肝是一种无过量饮酒史,与遗传-环境-代谢应激相关性疾病,导致肝相关性患病率和病死率升高的主要原因之一。非酒精性脂肪肝的发病机制尚未完全明确,也无疗效理想的治疗药物。治疗策略主要是减肥,合理控制血糖和血脂并去除其他引起肝病的病因,酌情选用相关药物辅助治疗。
