Graph coloring, minimum-diameter partitioning, and the analysis of confusion matrices

It is well known that minimum-diameter partitioning of symmetric dissimilarity matrices can be framed within the context of coloring the vertices of a graph. Although confusion data are typically represented in the form of asymmetric similarity matrices, they are also amenable to a graph-coloring perspective. In this paper, we propose the integration of the minimum-diameter partitioning method with a neighborhood-based coloring approach for analyzing digraphs corresponding to confusion data. This procedure is capable of producing minimum-diameter partitions with the added desirable property that vertices with the same color have similar in-neighborhoods (i.e., directed edges entering the vertex) and out-neighborhoods (i.e., directed edges exiting the vertex) for the digraph corresponding to the minimum partition diameter.

序列学习中的内隐学习效应

该研究采用较为复杂的包含图形出现的位置规则和顺序规则的实验材料,通过对比被试直接测验和间接测验、内隐学习和外显学习成绩的异同,考察了序列学习中的内隐学习效应,并探讨了规则特点对内隐学习效应的影响。结果表明,在图形位置的序列学习中存在内隐学习效应,内隐学习效应的大小受规则特点的影响。     

测量内隐态度的情感错误归因程序

情感错误归因程序（AMP）是一种新近发展出来的以投射为基本原理的内隐社会认知研究方法。AMP的内部处理机制可分为情绪的激发、归因以及猜测三个过程,每种过程都有其发生概率。AMP具有良好的信度和效度,最突出的特点是其对警告的抗拒性。此外虽作为一种相对性的内隐测量工具,但AMP也能很好地研究单一的态度对象。还介绍了几种新近出现的AMP改进范式。     

The role of faith in intuition, need for cognition and method of attitude formation in implicit–explicit brand attitude relationship strength

We tested the hypothesis that Faith in Intuition (FI) would moderate implicit–explicit attitude relationship strength for attitudes formed via associative processes, but not propositional processes. Experiments 1 and 2 demonstrated that FI moderated I–E relationship strength for attitudes formed via evaluative conditioning. High FI people had stronger I–E correlations. Experiment 2 showed that FI did not moderate I–E relationship strength for attitudes formed via propositional reasoning. Those low in Need for Cognition (NC), however, showed stronger I–E correlations than those high in NC. The importance of considering trait variables in combination with the method of attitude formation is discussed.     

Implicit attentional orienting in a target detection task with central cues

Studies using Posner’s spatial cueing paradigm have demonstrated that participants can allocate their attention to specific target locations based on the predictiveness of preceding cues. Four experiments were conducted to investigate attentional orienting processes operating in a high probability condition (cues 75% predictive) as compared to a low probability condition (cues 50% predictive) using various types of centrally-presented cues. Spatially-informative cues (arrows and circles with gaps) resulted in cueing effects (CEs) for both probability conditions, with significantly larger CEs in the high probability conditions than the low probability conditions. Participants in the high probability conditions reported little or no awareness of cue–target probabilities after task completion. Our results provide support for an implicit learning account of the proportion valid effect under experimental conditions involving spatially-informative central cues and relatively short stimulus onset asynchronies (SOAs).     

Measuring strategic control in artificial grammar learning

In response to concerns with existing procedures for measuring strategic control over implicit knowledge in artificial grammar learning (AGL), we introduce a more stringent measurement procedure. After two separate training blocks which each consisted of letter strings derived from a different grammar, participants either judged the grammaticality of novel letter strings with respect to only one of these two grammars (pure-block condition), or had the target grammar varying randomly from trial to trial (novel mixed-block condition) which required a higher degree of conscious flexible control. Random variation in the colour and font of letters was introduced to disguise the nature of the rule and reduce explicit learning. Strategic control was observed both in the pure-block and mixed-block conditions, and even among participants who did not realise the rule was based on letter identity. This indicated detailed strategic control in the absence of explicit learning.     

内隐性别刻板印象与自尊的关系研究

为了考察内隐性别刻板印象的存在广度,以及探讨它与自尊的关系,本研究采用内隐联想测验(IAT)和自尊量表(SES)考察65名大学生被试的内隐性别刻板印象和自尊水平,得出以下结论:一、大学生中普遍存在着内隐性别刻板印象,并且不同性别的内隐性别刻板印象不具有显著差异。二、有内隐性别刻板印象的人群中,不同性别的自尊水平差异不显著。三、内隐性别刻板印象与个体自尊水平的相关不显著。     

Hewitt多维完美主义量表在中学生群体中的修订

本研究以中学生群体为样本,对Hewitt多维完美主义量表(HMPS)进行修订。首先根据我国文化背景和青少年发展的具体状况建立了理论构想,接着对原量表进行了四次测查和检验修订,我们首先把指向他人和社会期望两个维度上的反向题改成正向题,并对所有项目的表述做了必要的修改;然后根据随后的测查结果进行了各维度和项目上的修改;最后删除了指向自我维度上的1个项目、指向他人维度上的2个项目和社会期望维度上的6个项目,修订后的HMPS量表的内部一致性信度α系数为0.91,指向自我、指向他人、社会期望的α系数分别为0.89,0.80,0.78,重测信度分别为0.80,0.79,0.67,与Frost多维完美主义量表中文修订版的相关分别为0.58,0.38,0.57。
