关联效应中对情绪诱词的错误再认的实验研究

采用DRM范式,考察了在汉字单字词语音关联和形声关联条件下对具有情绪色彩的关键诱词的错误再认情况,结果表明:(1)汉字中存在着语音和字形关联,但是语音关联下的对诱词的错误再认率很低。(2)语音关联、形声关联条件下,尽管学习阶段没有出现带有情绪色彩的词,被试仍然对情绪诱词都产生了显著的错误再认。(3)形声关联下对关键诱词的错误再认近于语音关联的两倍,可见概括性的强度影响错误记忆的大小。     

自尊和同伴压力对关联性错误记忆的影响

目的:探索不同自尊水平的初中生在无同伴压力或有同伴压力下完成记忆任务时,产生的关联性错误记忆情况.方法:使用自尊量表(SES)从78名中学生中挑出高自尊和低自尊学生42人,采用错误记忆研究的DRM范式,探讨自尊、同伴压力对关联性错误记忆的影响.结论:(1)关键诱饵的错误再认率高于有关项目和无关项目,有关项目的错误再认率高于无关项目；(2)自尊和同伴压力对关联性错误记忆会产生影响,高自尊和低自尊被试在有无同伴压力条件下对三种未学习词的错误再认率有所不同；在有同伴压力条件下,三种未学习词的错误再认率在高自尊被试和低自尊被试间都不存在显著差异,产生了记忆一致性效应.     

高低字频对汉字记忆中错误联接的影响

通过实验考察高低字频对汉字记忆中错误联接的影响.实验表明,汉字再认记忆中出现了频率的镜子效应,但在反应时间限制下,镜子效应中对学习词的正确再认率的差异消失.被试对低频联合诱字的错误再认率高于高频联合诱字.无论是高频字还是低频字,被试对联合诱字的反应时都长于对学习字和无关字的反应时.研究结果可用修正后的激活混淆来源理论(source of activation confusion,SAC)解释.     

测试阶段启动导致的错误记忆

该研究采用DRM范式探讨测试阶段启动导致的错误记忆现象。实验一采用传统"测试诱导启发程序"探讨关键诱饵前词数以及关键诱饵前词是否启动关键诱饵对错误再认的影响。实验二改进传统"测试诱导启发程序"排除反应定势影响下进一步考察实验一两自变量对关键诱饵错误再认的影响。结果表明:(1)测试阶段的启动确实对错误记忆有影响,关键诱饵前呈现6个词比呈现3个词引发更多的错误记忆,但是比起学习阶段的语义联想激活测试阶段的语义启动效应很微弱,关键诱饵前呈现启动词与非启动词对错误记忆影响不显著。(2)在排除反应定势后的不确定条件下,"赌徒谬误"心理对被试判断起一定作用。     

非熟练中—英双语者跨语言长时重复启动效应

采用跨语言长时重复启动研究范式进一步探讨非熟练中－英双语者的记忆表征模型。被试为华南师范大学大一本科生共140名。实验自变量是语言条件（同语言和跨语言）和学习状况（学习过的和未学习过的）,实验因变量是单词判断的反应时和正确率。实验1中被试在学习和测验阶段都完成概念任务,结果表明获得了跨语言长时重复启动效应。实验2中被试在学习和测验阶段完成词汇任务,结果表明没有获得跨语言长时重复启动效应。实验3中被试在学习阶段完成概念任务,在测验阶段完成词汇任务,结果表明没有获得跨语言长时重复启动效应。实验4中在学习阶段的概念任务中呈现汉语单字词,在测验阶段的词汇任务中呈现英语翻译对等词,结果表明没有获得跨语言长时重复启动效应。总的实验结果表明,在基于内隐记忆的跨语言重复启动的范式下,非熟练中－英双语者的记忆表征支持概念表征共享、词汇表征分离的观点。更重要的是,非熟练中－英双语者需要经由汉语翻译对等词的词汇表征,才能通达英语单词的概念表征,支持了词汇连接模型的观点     

重复学习对错误记忆通道效应的影响

本研究采用DRM范式以80名大学生为被试对错误记忆的通道效应进行了研究.实验采用三因素混合设计,运用信号检测论等方法探讨了重复学习对不同通道错误再认的影响.结果发现:1)汉语词表具有与英文词表不同的通道效应,表现为视觉学习的错误再认高于听觉学习;2)重复学习对视觉学习与听觉学习的错误再认产生分离性影响,即重复学习降低了视觉学习的错误再认,却提高了听觉学习的错误再认;3)信号检测论的分析表明:听觉学习在重复学习后对关键诱词的错误再认的增加是听觉学习对要义信息日益增加的敏感性连同较为宽松的提取标准协同起作用的结果.     

强大的错误记忆效应:词表呈现时间与呈现方式的影响

本研究采用DRM范式(Deese-Roediger-McDermott paradigm),考察了词表项目的呈现时间与呈现方式对错误记忆效应的影响。结果发现,被试对关键诱饵的错误再认受到学习阶段词表项目的呈现方式的影响,表现为所有项目随机呈现条件下的错误再认明显低于分组呈现条件,尤其是在20ms的随机呈现条件下,观察到了对关键诱饵的最低错误再认率。说明在对词表项目的编码阶段产生了对关键诱饵的连续激活,而对关键诱饵的错误记忆则是基于连续激活的不断累积的结果,当词表项目的随机呈现阻断了连续激活过程时,便会有效降低错误记忆效应。而且,在所有实验条件下均发现了错误记忆效应产生中所伴随的强烈主观体验,证实了错误记忆是一种强大的效应。     

表象编码对基于词表的错误记忆的影响

采用DRM范式,探讨不同表象编码时间和不同表象编码加工程度对基于词表的错误记忆的影响。在学习阶段,被试对呈现的词进行记忆。在测试阶段,被试在每个词列表学习结束后立即对该词列表进行自由回忆,分心任务结束后进行再认测试。实验结果发现：（1）被试在5秒编码条件下的错误记忆率显著低于3秒编码条件下的错误记忆率;（2）在5秒表象编码时间条件下,深加工组被试的错误记忆率显著低于浅加工组。这说明在较长的编码时间里,时间越长记住的细节信息越多,错误记忆率越低;加工程度越深,错误记忆率越低。

DRM范式下心境一致性错误记忆的认知机制

本研究以自编情绪DRM词表为实验材料, 用音乐诱发正常大学生被试正性、负性和中性心境, 探讨在被试处于某种心境下时是否产生心境一致性错误记忆现象、预警能否减少心境一致性错误记忆的发生。结果表明, 正性关键诱饵在正性心境下的错误再认率显著高于中性和负性心境, 负性关键诱饵在负性心境下的错误再认率显著高于中性和正性心境, 说明正常被试也会产生心境一致性错误记忆; 预警和无预警条件下被试对关键诱饵和心境一致性关键诱饵的错误再认率无显著差异, 说明外显的预警提示并不能消除部分由无意识产生的错误记忆和心境一致性错误记忆。研究结果支持记忆的扩散激活理论和情感的联想网络理论。     

Children's Representations of the World of Drugs

The changing profile of drug use has highlighted the need for age-appropriate education which requires insight into children's representations of drugs. Representations were elicited from 134 children aged between 5 and 11 years, drawn from two schools, by asking them to draw and write their responses to questions relating to a story about losing and finding a bag of drugs. Relevant responses were generated by 119 children aged between 8 and 11 years. A content analysis of these responses revealed differences with school and age. Older children were more likely to recognize that drugs can be good or bad depending on type, quantity taken and reason for use. The children had firm ideas about who takes drugs and their motivations and were knowledgeable about methods of use. They recognized that drugs can be dangerous, but had little understanding of how or why. The children's representations were characterized by fear and uncertainty and most wanted to know more. These findings are used to argue that there is a need for child-centred constructivist approaches to drug education which seek to demystify drugs and drug use and to orientate children to the realities of the world of drugs in the 1990s.     

On Complete Representations of Reducts of Polyadic Algebras

Following research initiated by Tarski, Craig and Németi, and futher pursued by Sain and others, we show that for certain subsets G of ^ω ω, atomic countable G polyadic algebras are completely representable. G polyadic algebras are obtained by restricting the similarity type and axiomatization of ω-dimensional polyadic algebras to finite quantifiers and substitutions in G. This contrasts the cases of cylindric and relation algebras. Presented by Robert Goldblatt     

小学生数学问题解决中视觉空间表征的研究

本研究区分了两类数学应用题:非视觉化题目与视觉化题目,采用数学测验与个别访谈相结合的方法,考察了54名小学四、五、六年级不同学业水平学生的视觉空间表征。结果表明:图式表征在非视觉化题目与视觉化题目上都极大地促进了问题解决,图像表征妨碍非视觉化题目的解决但与视觉化题目的解决无关,并提出图式表征和图像表征在两类题目上有不同的含义。六年级学生的解题成绩及图式表征有显著的提高,但图像表征与年级因素无关。差生的图式表征能力很差,而在视觉化题目上使用图像表征显著地多于优生及中等生。在非视觉化题目的非视觉空间表征与图式表征之间的转换灵活性上,优生表现了明显的优势。     

Representations of handguns by young adults in the US and UK

The representation of handguns by a sample of university students (n = 96) from one of the southern states of the US, was contrasted with that of a sample of university students in the UK (n = 100), employing ANOVA and Hierarchical Cluster Analysis. Exploring the structure of response, the findings showed little evidence for a common cross‐locational representation of handguns for the US and UK samples taken together. There was support for the existence of distinctive locational representations, some support for gender‐specific representations, and strong support for representations of handguns according to particular combinations of locality and gender. Representations of handguns by US males from the southern states were the most distinctive, complex and integrated in structure, bringing into question simplistic assumptions concerning the nature of an alleged ‘southern sub‐culture of violence’ or of a more general ‘gun culture’.

Social Representations: A Normative and Dynamic Intergroup Approach

This commentary outlines an approach to social representations which emphasizes the normative and dynamic nature of shared knowledge. Social representations both connect and divide people, for example through shared ingroup and outgroup stereotypes derived from antagonistic social representations. Through asymmetrical intergroup communication and influence, in turn, social representations are formed, maintained, and contested. In this dynamic process, powerful majorities attempt to define the meaning of new or otherwise important information as a function of their group norms, while subordinate minorities employ propaganda techniques of social influence to resist majority influence and propose alternative positions.

Visualized Collective Memories: Social Representations of History in Images Found in Finnish History Textbooks

This study focuses on visual collective memory, a topic that has long been neglected in the social sciences and particularly in social psychological research on social representations of history. It explores the contents and meanings of images in the construction of Finnish national history. Through examination of official history writing, a better understanding is sought of how collective memory is constructed as part of history politics. The data for the present study consist of images (N = 541) included in recent textbooks on Finnish history. Barthes' three‐meaning approach is used in combination with qualitative content analysis to examine a large corpus of images. The visualized collective memory is approached from five perspectives: (i) the years of memory; (ii) the places of memory; (iii) the themes of memory; (iv) the main actors and (v) the silence of memory. The investigation shows that, in official discourse, politics, culture and war are the main contents of Finnish visual collective memory. The key actors in the narrative are politicians, especially the eighth president of Finland, Urho Kekkonen. The most important moments in time are situated in the war years 1918 and 1939, while the geographical focus is the central square in the capital, Helsinki. The result is a national history that is positive, homogeneous and exclusive. Copyright © 2016 John Wiley & Sons, Ltd.     

The Formal Structure of Kind Representations

Kind representations, concepts like table, triangle, dog, and planet, underlie generic language. Here, we investigate the formal structure of kind representations—the structure that distinguishes kind representations from other types of representations. The present studies confirm that participants distinguish generic-supporting properties of individuals (e.g., this watch is made of steel) and accidental properties (e.g., this watch is on the nightstand). Furthermore, work dating back to Aristotle establishes that only some generic-supporting properties bear a principled connection to the kind, that is, are true of an individual by virtue of its being a member of a specific kind (e.g., telling time for a watch). The present studies tested the hypothesis that principled connections are part of the formal structure of kind representations. Specifically, they tested whether they structure a newly learned kind representation. Experiment 1 found that introducing a property of a newly encountered novel kind in any one of four linguistic frames that provide evidence that a property has a principled connection to a kind (e.g., “It has fur because it is a blick”) led participants to infer a different conceptual consequence of principled connections (i.e., “There is something wrong with this blick, which does not have fur”) for which they had no direct evidence. Two introduction frames that provided no evidence for principled connections (e.g., “Almost all blicks have fur”) did not generate the same consequence. Experiment 2 found that all of the targeted properties were generic licensing, irrespective of the introduction frame. That the distinction between properties that bear principled connections to their kinds, and merely generic-supporting properties structures novel kind representations, provides strong evidence that this distinction is part of the formal structure of kind representations.     

Power and Participation: Social Representations among Children in Pre-school

Children’s play is usually connected with qualities such as happiness and innocence, and regarded as important and necessary for learning and development. However, play is not always a state of joy. Experiences of being socially excluded or ignored and of taking part in such activities are occurring. The article draws on a re-analysis of empirical data from a study of pre-school children’s play. The focus in the article is directed towards how pre-school children within the context of play communicate and act in relation to social participation and power. The theoretical framework is built upon a socio-cultural research tradition, particularly emphasising context and communication. Interpretive reproduction, secondary adjustment, and social representations are used as additional theoretical concepts in the analyses and discussions of the results. Empirical data show that children’s social representations of power and participation in play include rationales for who can join the play and who can not, and also how to allow exceptions from the main rule that ‘anyone can join’.
