短时存贮与复述动态分离的ERP证据

工作记忆参与信息的短时贮存和操作加工。为了分离参与词语短时存贮与复述的脑区及其时间过程,测量并比较了14名正常青年被试进行汉字2-back、0-back和复述任务时的事件相关电位(ERPs)。结果发现,2-back任务减复述任务在头皮后部出现差异波N430,可能反映了信息的短时存贮及其时间进程。2-back任务减0-back任务在头皮前部得到的持续负成分SNC可能是复述加工的动态指标。SNC和N430持续时间的重叠提示,大脑额叶和后部区域分别参与信息的复述和短时存贮,两者的动态分离加工可能是工作记忆中暂时保持的神经基础。     

小学教师科学素养的调查研究

为了解大连地区小学教师科学素养的现状,采用自编调查问卷对265名大连市城乡小学教师进行了调查研究。结果表明:1)本、专科学历小学教师的科学素养明显高于中专学历的教师;2)小学教师较好地掌握了小学水平的科学知识,但对中学以上水平的科学知识掌握较差;3)教师的科学素养水平没有表现出随教龄的增长而提高。     

中国大陆、香港和美国大学生主观幸福感比较

采用量表法对中国大陆、香港和美国三个地区的大学生被试的主观幸福感(SWB)进行了比较。差异检验表明,在总体SWB水平上,三个地区没有表现出显著差异,但在生活满意感、积极情感和消极情感维度上差异都显著。分层回归的结果发现,经济状况、社会关系和外在价值变量对三个地区大学生的生活满意感和积极情感都作出了增值贡献;外在准则变量对三个地区的消极情感作出了增值贡献。     

儿童"零"概念形成的实验研究

该研究通过3项系统实验探讨了学前至小学低中年级儿童视野、掌握和应用“零”概念的发展水平。结果表明,学前至小学低中年级儿童对“零”概念的理解、应用“零”进行加减运算、乘除运算的能力都是不断提高的。但是。对于把“零”作为除数或被除数的理解要落后于将其作为乘数或被乘数使用的理解。最后,综合三项实验结果进行了总体讨论。     

意识和无意识权衡现象的四个特征

本实验以探讨意识和无意识之间的复杂关系为目的 ,采用 5 (年龄 :老年、中年、大学生、初三和高小 )× 2 (贡献来源 :意识和无意识 )的两因素混合设计 ,通过加工分离程序 (PDP)的包含和排除测验 ,计算意识和无意识的贡献大小。结果表明在对具体图片的记忆中 ,1)意识和无意识贡献出现了发展上的分离 ;2 )老年组的无意识贡献高于意识贡献 ,但未达到显著水平 ,其余四个组别则表现出意识贡献水平极其显著地高于无意识贡献水平。在此基础上 ,本研究对意识和无意识的权衡现象的四个特征 (相互独立、相互作用、互为主次、互相依存 )分别进行了阐述     

Impact of telepresence levels on internet advertising effects.

This study examined the dimensions of interactivity and vividness to propose three telepresence levels: content presence, social presence, and personal presence. Then, an experiment investigated the impact of different telepresence levels on Internet advertising. The effects of interactions between vividness of visual imagery (VVI) and product types in relation to telepresence levels and advertising effects were also analyzed. The study employed a factorial design: 4 (levels of telepresence) x 2 (product types) x 2 (VVI). Levels of telepresence and product types were both manipulated between subjects. VVI was measured within subjects. Experimental findings showed that high levels of telepresence of an Internet advertisement increased subject recall and recognition. The low VVI respondent group would have greater recognition than traditional advertisements when respondents were exposed above the level 2 (social presence) advertisement and the effect of recognition increased from level 1 (content presence) to level 3 (personal presence). Recognition increased from level 1 (content presence) to level 2 (social presence) for both search and experience product groups; however, only recognition of the experience product group increased in level 3 (personal presence).     

Cognitive-Behavioral Therapy With Chinese Americans: Research, Theory, and Clinical Practice

In this article, we discuss how to conduct cognitive-behavioral therapy with Chinese Americans. We present an integration of theory, research, and clinical practice to help mental health practitioners understand how Chinese culture may potentially influence the CBT treatment process for Chinese immigrants. Several recommendations are provided as to how to adapt and modify CBT to better meet the therapeutic needs of Chinese American clients. A case example demonstrates how cultural modifications of CBT can lead to effective psychotherapy outcomes for Chinese American clients.     

Gender differs: Modelling knowledge sharing from a perspective of social network ties

The present paper proposes a model of knowledge sharing, in which coworker congruence, outcome interdependence, perceived organizational support, and procedural justice influence knowledge sharing indirectly through the mediation of instrumental ties and expressive ties, and examined gender differences in causal connections within the model. In a sample of employees in Taiwan, it was shown that the influence of instrumental ties on knowledge sharing is stronger for females than for males; the influence of expressive ties on knowledge sharing is stronger for males than for females; the influence of coworker congruence on expressive ties is stronger for females than for males; the influence of outcome interdependence on instrumental ties is stronger for females than for males; and the influence of perceived organizational support on instrumental ties is stronger for males than for females.     

自尊水平划分方法与青少年自尊的现状

本文采用问卷法调查了349名中学青少年的一般自尊,通过三种自尊水平划分方法的结果比较,确定当代青少年中不同自尊水平的人数比例。结果表明:1青少年一般自尊状况接近正态分布,一般自尊水平普遍偏高;2总体来看,三种一般自尊水平青少年占青少年总数的比例是:高自尊38%,中等自尊52%,低自尊10%;男生、女生的各一般自尊水平的人数比例与总体各自尊水平的人数比例相近。     

5～9岁儿童极限概念认知发展的实验研究

皮亚杰(1985)认为儿童非要到11或12岁时才能掌握极限的概念。这个观点十分让人感兴趣,然而在众多文献中却很难发现相关研究。本研究运用实验法研究了5、6、7、9四组儿童的极限概念。结果表明:儿童在极限概念的发展存在两个快速期,即5~6岁和6~7岁;5岁儿童处于极限概念萌芽状态,6岁儿童有了部分极限概念,7岁儿童极限概念有了进一步发展但不稳定;9岁儿童开始接近有了极限概念,但仍未到达完全理解。本研究结果支持了皮亚杰的相关观点。
