网络旗帜广告的记忆效果

由于人们对网络旗帜广告效果的质疑,在网络广告的计费方式上也出现了两种计价模式,分别为按照浏览率和点击率来计量广告效果。其本质问题在于单纯浏览是否能够产生广告效果,以及浏览和点击各自所能带来的广告效果差异有多大。本研究利用模糊测量及相应统计方法,就上网者对网络旗帜广告的记忆效果进行测量。结果显示,在单纯浏览的情况下,上网者对网络旗帜广告已经留有印象,但这种记忆效果并不随着浏览次数的增加而显著改善;点击所能带来的广告记忆效果约为单纯浏览对应效果的1.4~1.5倍     

3．5～5．5岁学前儿童年龄认知发展的研究

该实验采用三个问题作业(“年龄比较”、“出生年龄”、“年龄变化”)及一个“图示作业”,调查了60名3．5～5．5岁儿童年龄认知的发生、发展情况,结果表明：3．5岁儿童处于年龄认知萌芽状态,4．5岁儿童年龄认知开始发生,5．5岁儿童的年龄认知已发展到较高水平。儿童年龄认知变化可用变化分割模型(简称CS模型)来解释。     

Imagining stereotypes away: the moderation of implicit stereotypes through mental imagery.

Research on implicit stereotypes has raised important questions about an individual's ability to moderate and control stereotypic responses. With few strategies shown to be effective in moderating implicit effects, the present research investigates a new strategy based on focused mental imagery. Across 5 experiments, participants who engaged in counterstereotypic mental imagery produced substantially weaker implicit stereotypes compared with participants who engaged in neutral, stereotypic, or no mental imagery. This reduction was demonstrated with a variety of measures, eliminating explanations based on response suppression or shifts in response criterion. Instead, the results suggest that implicit stereotypes are malleable, and that controlled processes, such as mental imagery, may influence the stereotyping process at its early as well as later stages.     

Culture, Change, and Prediction

Five studies showed that Chinese and Americans perceive change differently. Chinese anticipated more changes from an initial state than Americans did. When events were changing in a particular direction, Chinese were more likely than Americans to predict change in the direction of change. Moreover, for patterns with changing slopes, Chinese predicted greater change in the way slopes changed, in comparison to Americans. In addition, people who predicted change were perceived as wise by Chinese more than by Americans. Implications for social attribution, tolerance for contradiction, persistence on tasks, and the illusion of control are discussed.     

基于行为的绩效评定方法的研究进展

从20世纪60年代至今,基于行为的绩效评定一直是各类组织的主要绩效评定方法。基于工作结果的非判断性绩效测量有其难以克服的局限,各种基于工作行为的判断性绩效测量方法相继开发出来。行为指标的筛选成为研究的主要问题之一。组织公民行为、区分作业绩效与关系绩效等研究,向基于行为的绩效评定提出了新的问题。     

社会建构论心理学对维果茨基思想的继承和发展

维果茨基理论为社会建构论的产生与发展奠定了基础,社会建构论从维果茨基思想中汲取了丰富的营养,并从多方面丰富发展了维果茨基的社会建构思想。社会建构论心理学沿袭了维果茨基的反叛精神,继承并发展了维果茨基倡导的认识论和发展观,借鉴了维果茨基提出的工具论和方法论,对现代心理学的基本预设进行了根本性动摇和冲击     

加压素对记忆巩固过程作用的研究 Ⅲ.GABA能药物对加压素易化大白鼠被动回避反应的影响

本文以平台被动回避反应为行为模式,采用侧脑室微量注射AVP和GABA能受体激动剂蝇蕈醇(Muscimol)、受体拮抗剂印防己毒素(Picrotoxin),进一步研究了AVP易化记忆巩固效应及与中枢GABA能系统的关系。主要实验结果如下: 1.AVP对被动回避行为模式的学习训练过程无促进作用,但促进了这种行为的记忆巩固过程,注射AVP的动物记忆保持能力显著高于对照组动物,有效剂量为30ng/大鼠。 2.侧脑室注射100ng/大鼠蝇蕈醇后,AVP仍非常显著地保持其行为效应,但注射100ng/大鼠印防己毒素后,AVP的效应已见下降,剂量增至300ng/大鼠后,AVP的效应已被完全消除。 实验结果再次提示,加压素具有促进记忆巩固过程的中枢性效应,脑内GABA能神经元的活动可能参与了这种效应。     

Interpolation and amalgamation properties in varieties of equivalential algebras

Important positive as well as negative results on interpolation property in fragments of the intuitionistic propositional logic (INT) were obtained by J. I. Zucker in [6]. He proved that the interpolation theorem holds in purely implicational fragment of INT. He also gave an example of a fragment of INT for which interpolation fails. This fragment is determined by the constant falsum (), well known connectives: implication () and conjunction (), and by a ternary connective defined as follows: (p, q, r)= ^df (pq)(pr).Extending this result of J. I. Zucker, G. R. Renardel de Lavalette proved in [5] that there are continuously many fragments of INT without the interpolation property.This paper is meant to continue the research mentioned above. To be more precise, its aim is to answer questions concerning interpolation and amalgamation properties in varieties of equivalential algebras, particularly in the variety determined by the purely equivalential fragment of INT.
