内隐记忆中通道效应的认知与神经机制

通道转换是使内隐和外显记忆任务之间产生功能性分离经常操纵的典型变量之一,被看作是内隐记忆主要依赖刺激知觉住处加工的有利语气。该文回顾了近些年通道效应实验和理论研究的有关文献。对产生通道效应的认知机制和神经解剖基础进行了总结和分析,并提出了有待于进一步验证的问题。     

句子语境中语义联系效应和句法效应的研究

通过对比研究句子语境中句法成分和语义联系对目标词加工的不同影响,来探讨句子语境的作用机制和作用点问题。实验一采用词汇命名任务研究发现,句法违反对词汇命名会产生抑制作用,而语义违反对词汇命名却没有发现抑制作用。实验二利用词汇决定任务发现,句法和语义成分影响词汇决定任务,句法违反和语义违反对词汇决定任务均会产生抑制作用。结果表明,句子语境加工中,对内容词语义整合过程中存在一个句法成分的独立加工水平。     

大学教师教学效果评价维度结构及影响因素研究

本文用协方差结构模型方法,对大学教师教学效果的评价结构维度以及维度结构关系和影响因素进行分析。结果表明：(1)教学绩效评价具有七个维度;(2)七个维度之间具有一定的因果关系：知识宽度、人际和谐为外源影响变量,教学热情、师生互动、教学管理、功课量为中介变量,学习价值感为结果变量;(3)评价问卷具有跨专业、跨年级稳定性,并不受课程类别影响,说明评价问卷具有很高的信度。     

句子语境中语义联系启动作用的研究

通过对比研究正序和乱序两种句子语境对目标词加工的不同影响,来探讨句子语境中语义联系启动作用及作用点问题。实验一采用词汇命名任务研究发现,句法成分影响命名任务,句法违反对命名任务产生较大的抑制作用。语义违反则对命名任务没有产生显著的抑制作用。实验二利用词汇决定任务发现,词序影响决定任务,乱序对词汇决定产生很大的抑制作用。语义违反对决定任务地产生较大的抑制作用。结果表,中义联系启动是短暂的,它的保持和传递需要句法成分的支持。     

Making a Party Leader Less of a Party Member: The Impact of Ambivalence on Assimilation and Contrast Effects in Political Party Attitudes

The present study tested the degree to which attitudes about a political party would be influenced by the context in which the party leader was rendered cognitively accessible. A sample of British undergraduates evaluated Prime Minister Tony Blair before expressing their opinion about the Labour party. In one condition, the two items were structured such that Blair was expected to be included in participants' representation of the party. In a second condition, the same items were structured such that Blair was expected to be excluded from participants' representation of the party. The results supported the hypothesis that manipulating the context in which Blair was made salient would produce different effects on a subsequent judgment of the Labour party, but only among politically ambivalent respondents.     

Framing the Lewinsky Affair: Third-Person Judgments by Scandal Frame

Recent studies have documented a “third-person effect” whereby people are found to judge others as more influenced than themselves by the mass media. Meanwhile, contemporary research on issue framing has demonstrated the powerful role of mass media in shaping people's political judgments. But are the perceptual judgments that define third-person effects sensitive to how the media frame an issue? Two studies investigated this question in the context of the Lewinsky-Clinton scandal, one in late August 1998 and the other during spring 1999. Several hundred undergraduates in each study were randomly assigned to one of two media frames. In the 1998 study, the political scandal was depicted as a matter of sexual indiscretion by the president or as legal wrongdoing; in the 1999 study, the recently concluded impeachment process was depicted as the consequence of partisanship or of Clinton's actions. The participants’ judgments of media influence on themselves and on the public were then recorded. The results show that third-person effects were sensitive to issue framing, but change occurred primarily in participants’ judgments about their own vulnerability to media influence.     

基线选择影响词语认知启动实验结果的研究

探讨了词语认知启动实验中,启动基线的选择问题。一项有关汉字识别中形音义激活时间进程的实验表明：是采用无关字启动还是采用图形符号启动作为衡量启动效应的基线,会对词语认知启动实验的结果产生不同的影响。根据本研究结果,对词语认知启动实验中基线的选择问题提出了建议。     

模板理论与限制调节理论的比较研究

直接针对专家记忆优势效应的理论主要有两个,模板理论和限制调节理论。模板理论认为,专家记忆优势效应是由于专家将许多模板存储于长时记忆中;而限制调节理论认为,专家记忆优势效应是由于专家能够抽取与目标关联的限制来建构刺激物。文章以中国象棋为实验材料．对两个理论进行了比较,实验结果否定了限制调节理论。     

Neighborhood Effects Examined Through the Lens of Residential Mobility Programs

Although researchers have consistently found that neighborhoods matter, relatively little is known about the processes through which neighborhood-level characteristics influence individual outcomes, and whether interventions targeting improving neighborhood characteristics will be beneficial for children. I examine whether relocating from high- to low-poverty neighborhoods affected low-income Black children's exposure to promotive developmental experiences. Participating families voluntarily relocated from high-poverty, minority segregated, inner-city Chicago neighborhoods to mostly White, low-poverty, suburban and Chicago neighborhoods. Data come from retrospective qualitative interviews with 22 Gautreaux One families an average of 15 years after initial relocation, and from interviews with 43 Gautreaux Two families as they relocated into their new communities. I find that children primarily benefited from the institutional versus the social interaction resources in their new neighborhoods. Furthermore, suburban placement was key in facilitating children's access to higher quality resources.     

Disaggregating the Distal,Proximal, and Time-Varying Effects of Parent Alcoholism on Children’s Internalizing Symptoms

We tested whether children show greater internalizing symptoms when their parents are actively abusing alcohol. In an integrative data analysis, we combined observations over ages 2 through 17 from two longitudinal studies of children of alcoholic parents and matched controls recruited from the community. Using a mixed modeling approach, we tested whether children showed elevated mother- and child-reported internalizing symptoms (a) at the same time that parents showed alcohol-related consequences (time-varying effects), (b) if parents showed greater alcohol-related consequences during the study period (proximal effects), and (c) if parents had a lifetime diagnosis of alcoholism that predated the study period (distal effects). No support for time-varying effects was found; proximal effects of mothers' alcohol-related consequences on child-reported internalizing symptoms were found and distal effects of mother and father alcoholism predicted greater internalizing symptoms among children of alcoholic parents. Implications for the time-embedded relations between parent alcoholism and children's internalizing symptoms are discussed.
