Multilevel analysis of individual differences in regularities of grapheme–color associations in synesthesia

Grapheme–color synesthesia is a neurological phenomenon where visual perception of letters and numbers stimulates perception of a specific color. Grapheme–color correspondences have been shown to be systematically associated with grapheme properties, including visual shape difference, ordinality, and frequency. However, the contributions of grapheme factors differ across individuals. In this study, we applied multilevel analysis to test whether individual differences in regularities of grapheme–color associations could be explained by individual styles of processing grapheme properties. These processing styles are reflected by the type of synesthetic experience. Specifically, we hypothesized that processing focusing on shape differences would be associated with projector synesthetes, while processing focusing on ordinality or familiarity would be associated with associator synesthetes. The analysis revealed that ordinality and familiarity factors were expressed more strongly among associators than among projectors. This finding suggests that grapheme–color associations are partly determined by the type of synesthetic experience.     

大学生生活满意度判断的文化差异研究

对36个国家8007名大学生的生活满意度进行了问卷调查。多层线性模型分析(HLM)的结果表明:(1)积极情感体验、自我满意和社会关系满意度能显著正向预测生活满意度,而消极情感体验能显著负向预测生活满意度;(2)情感体验、自尊和社会关系满意度对整体生活满意度的预测力存在着显著的国家间差异;(3)个人主义———集体主义是导致生活满意度水平国家间差异的重要因素,同时也对自尊与生活满意度的相关有显著预测作用,但它并不影响情感体验和社会关系满意度与整体生活满意度之间的关系。     

成人在语境中的母语词汇意义学习

语境学习是成人获得词汇意义的主要方式, 大量研究者使用语境学习范式考察成人母语词汇意义学习的问题。已有研究将词汇意义学习分为两大阶段：习得词汇的对应概念阶段和将新词的意义整合到已有的语义网络中的阶段。基于词汇意义学习两大加工阶段中语境学习的相关研究, 梳理了词汇、语境、被试因素对成人词汇意义学习的影响, 指出未来研究需要进一步关注新概念学习、隐喻意义学习等问题。     

Ranking Alternatives on the Basis of Preference Relations: A Progress Report with Special Emphasis on Outranking Relations

This paper is devoted to the study of techniques allowing one to rank order the elements of a finite set on the basis of a non-necessarily complete or transitive binary relation. In the area of MCDM, such a problem occurs with outranking methods. We review a number of theoretical results concerning this problem and show how they may be useful in order to guide the choice of a particular technique. © 1997 John Wiley & Sons, Ltd.     

Outranking Relations: Do They Have Special Properties?

Outranking relations are most often built using a concordance–discordance principle. Such relations are in general neither transitive nor complete. This is not to say that the concordance–discordance principle does not impose some ‘structural’ restrictions on these relations. We show why this question may be of some importance for analysing the various techniques designed to build a recommendation on the basis of such relations. These restrictions are studied for the ELECTRE and PROMETHEE methods.
