Intergroup threat,social dominance,and the malleability of ideology: The importance of conceptual replication

Consistent with the theory of malleable ideology, research has shown that, under intergroup threat, antiegalitarian individuals will exploit the malleable character of color blindness and strategically claim to be strong supporters of it. In three studies conducted in France, we found no support for this theory when measuring color blindness but strong support when using measures of laïcité, an ideology of secularism. Indeed, those who score low on social dominance orientation (SDO) were more likely to support laïcité than antiegalitarian individuals. However, a situational threat (Study 1), a symbolic threat experimentally induced (Study 2), and a perceived symbolic threat (Study 3) were all related to increased support for laïcité by people high in SDO, without affecting those low in SDO. Thus, laïcité is a malleable ideology that can be adopted by individuals having contrasting motivations, as color blindness in the United States. Implications for the role of exact and conceptual replications in the development of a psychological science are discussed.     

The interaction between surface color and color knowledge: behavioral and electrophysiological evidence

In this study, we used event-related potentials (ERPs) to evaluate the contribution of surface color and color knowledge information in object identification. We constructed two color-object verification tasks - a surface and a knowledge verification task - using high color diagnostic objects; both typical and atypical color versions of the same object were presented. Continuous electroencephalogram was recorded from 26 subjects. A cluster randomization procedure was used to explore the differences between typical and atypical color objects in each task. In the color knowledge task, we found two significant clusters that were consistent with the N350 and late positive complex (LPC) effects. Atypical color objects elicited more negative ERPs compared to typical color objects. The color effect found in the N350 time window suggests that surface color is an important cue that facilitates the selection of a stored object representation from long-term memory. Moreover, the observed LPC effect suggests that surface color activates associated semantic knowledge about the object, including color knowledge representations. We did not find any significant differences between typical and atypical color objects in the surface color verification task, which indicates that there is little contribution of color knowledge to resolve the surface color verification. Our main results suggest that surface color is an important visual cue that triggers color knowledge, thereby facilitating object identification.     

Processing Speed Weakness in Children and Adolescents with Non-Hyperactive but Inattentive ADHD (ADD)

DSM-IV-TR defines ADHD-Predominantly Inattentive as allowing up to five symptoms of hyperactivity/impulsivity, while theories of the inattentive type usually assume a group that is hypoactive and characterized by processing speed and cognitive interference deficits. In a community-recruited sample of 572 children and adolescents, a pure inattentive subtype of ADHD (ADD) was defined as those who met DSM-IV-TR criteria for ADHD-PI but had two or fewer hyperactive/impulsive symptoms. Processing and output speeds of those with ADD were compared to those identified with DSM-IV-TR ADHD combined type and non-ADHD controls. These results were then contrasted with those found when DSM-IV-TR defined ADHD-PI was compared with ADHD-C and controls. Processing and output speed were assessed with the Trailmaking A and B and the Stroop Naming Tests. Cognitive interference control was assessed with the interference score from the Stroop Task. Slower cognitive interference speed was found in the ADD vs. ADHD-C and controls comparisons, but not the ADHD-PI versus ADHD-C and controls comparisons. On output speed measures, ADD exhibited the slowest performance, significantly different from controls and the effect size for the set-shifting speed contrast (Trailmaking B) was double that of the ADHD-PI vs. control comparison. ADHD-Inattentive type as defined by the DSM-IV-TR is a heterogeneous condition with a meaningful proportion of those affected exhibiting virtually no hyperactive/impulsive symptoms. This subgroup may represent a distinct inattentive condition characterized by poor cognitive interference control and slow processing or output speed.     

短期习得的语言范畴使成人大脑右半球颜色范畴知觉转为左半球颜色范畴知觉

本研究探讨了色词与颜色重组训练能否让被试习得与真实情境相似的色词与颜色范畴联结, 并引起相应的偏侧化颜色范畴知觉, 从而进一步揭示语言编码对颜色范畴知觉的影响。采用六种蓝色作为材料。B1与B2为先前研究的两种蓝色。B11和B12, B21和B22分别为使B1, B2变浅和变深所得, 四者是连续的蓝色。训练被试分别用“duān”和“kěn”命名B1和B2。由于被试可能习得色词与颜色范畴的联结, 因此B12与B21为可能变范畴间颜色, B11和B12, B21和B22为可能变范畴内颜色。训练前后分别让被试完成一个视觉搜索测验。结果发现：前测中可能变范畴间颜色的辨别优于可能变范畴内颜色, 且在左视野呈现时更显著; 后测中可能变范畴间颜色的辨别同样优于可能变范畴内颜色, 但在右视野呈现时更显著。这提示：(1)人们在知觉同一语言范畴的不同颜色时可能会区分深浅范畴, 并因此引发右半球颜色范畴知觉; (2)短期习得的语言范畴能引起偏左半球颜色范畴知觉, 且使右半球颜色范畴知觉转为左半球颜色范畴知觉; (3)被试在训练中习得了色词与颜色范畴的联结; (4)范畴学习可以在仅学习一个样例的条件下自动发生。     

红色和蓝色对中国汉族大学生情绪的启动效应

通过3个实验探讨红色和蓝色对中国汉族大学生的情绪意义。实验1采用限制联想法考察红色和蓝色的情绪意义。实验2、实验3采用启动范式, 分别考察在知觉水平和概念水平上红色和蓝色对情绪的启动效应。结果发现：(1)知觉水平：在唤醒度和优势度上, 红色知觉引发了高唤醒、高优势情绪, 蓝色知觉引发了低唤醒、低优势情绪, 这与国外研究基本一致; 但在愉悦度上, 红色知觉既能引发高愉悦情绪, 也能引发低愉悦情绪, 而蓝色知觉只引发了高愉悦情绪, 这体现出本土化特点。(2)概念水平：在唤醒度和愉悦度上, 红色概念引发了高唤醒、高优势情绪, 蓝色概念引发了低唤醒、低优势情绪, 这与知觉水平基本一致; 但在愉悦度上, 红色概念只启动了高愉悦情绪, 而蓝色概念同时启动了高愉悦和低愉悦的情绪, 这与知觉水平不一致。本研究表明：(1)红色和蓝色对中国汉族大学生情绪引发的特点主要表现在愉悦度上; (2)颜色知觉和颜色概念对情绪的引发机制可能具有如下特点：颜色知觉对情绪的三维度具有直接的引发作用; 而颜色概念对情绪唤醒度和优势度的引发是以颜色知觉为中介, 对愉悦度的引发则是以社会文化为原因。本研究探讨了红色和蓝色对中国汉族大学生情绪的作用, 对红色和蓝色在中国社会环境中的应用具有一定的实际价值; 同时, 直接比较并剖析了颜色知觉与概念对情绪的引发特点, 对于揭示二者对情绪引发的内部机制具有一定的理论意义。     

British men's hair color preferences: an assessment of courtship solicitation and stimulus ratings

Two studies examined the influence of women's hair color on approach behavior by British men and on ratings of physical attractiveness and personality. In Study 1, a female confederate whose hair color was dyed blonde, brunette, or red was instructed to sit in several nightclubs. It was found that she was approached significantly more frequently by men in the blonde condition. In Study 2, images of the same confederate were rated by 126 men. Results showed that the brunette stimulus was rated as more physically attractive, intelligent, approachable, competent, and arrogant, whereas the blonde stimulus was rated as more needy. These results are discussed in relation to the literature on hair color and attractiveness, but also in terms of women's own perceptions of their hair color.     

Axiomatizing hybrid products: How can we reason many-dimensionally in hybrid logic?

The aim of this paper is to propose a two-dimensional hybrid logic in order to formalize inferences containing both spatial and temporal propositions. The semantic idea behind the proposal is to name both horizontal and vertical lines in a 2D-plane by two kinds of nominals. This is a generalization of the idea of naming a point in one-dimensional hybrid logic. I give an axiomatization of the proposed two-dimensional hybrid logic and show that it enjoys a general completeness result (called pure completeness) with respect to product Kripke frames. Moreover, in order to capture $T\times W$-frames studied by R.H. Thomason (1984), I introduce the notion of a dependent product frame, which enables us to represent the dependence of space over time. I also give a complete axiomatization of this dependent two-dimensional hybrid logic, and, as a corollary, reveal that a hybridization of $T\times W$-logic enjoys strong completeness.     

Children's perceptions of intergroup and intragroup similarity and the role of social experience

Perceptions of intragroup and intergroup similarity were assessed in 1st grade (M = 6.78 years, SD = .42) and 4th grade (M = 9.79, SD = .51) boys and girls (N = 382) who attended either ethnically homogeneous or ethnically heterogeneous schools. Children's evaluations of same-race and cross-race friendships were also assessed. European-American children attending homogeneous and heterogeneous schools attributed greater homogeneity to the same-race Black dyads. European-American children attending homogeneous schools, furthermore, focused on skin color in their evaluations of similarity and friendship to a greater extent than did European-American and minority (i.e., African-American, Latin-American, Asian-American) children attending heterogeneous schools. Children attending heterogeneous schools were more positive about friendship in general than children attending homogeneous schools, suggesting that social experiences in school settings are an important context of children's intergroup contact experience. The findings indicate that children's intergroup contact influences their perceptions of similarity and reasoning about cross-race friendship.     

语言和文化影响颜色认知：直接语言效应抑或间接语言效应?

语言和文化对颜色认知的影响存在着直接语言效应和间接语言效应的争论。直接语言效应是指在识记颜色时人先将颜色转换成颜色名称, 再认时通过匹配保留在记忆中的颜色词与目标颜色名称来完成任务。颜色类别知觉是语言策略的结果。间接语言效应是指语言和文化塑造颜色知觉表征, 形成了一个曲形颜色知觉空间, 将人们的注意引向语言和文化定义的颜色类别分界。即使没有语言策略的参与, 类别效应也会出现。颜色文化是民族文化的重要组成部分。绿色和红色在维吾尔族和汉族的语言和文化中分别具有重要的意义。采用颜色相似性判断、颜色分类和颜色再认任务, 考察维吾尔族和汉族的大学生对红、绿的认知, 探查语言和文化对颜色认知的影响及其性质。结果表明, 与汉族相比, 维吾尔族对绿色的辨认、分类和再认存在反应优势, 对红色认知存在反应劣势。与颜色辨认反应比, 两个民族的颜色再认反应时显著长。整个研究表明, 语言和文化对颜色认知的影响存在着间接语言效应, 语言与文化塑造个体的颜色知觉空间。     

Interhemispheric interaction in word‐ and color‐matching of Kanji color words1

Abstract: The aim of the present study was to investigate the possibility that a shift toward a within‐hemisphere advantage would emerge when two stimulus items receive, respectively, different processing (vs. when they receive similar processing). Using right‐handed participants, we briefly presented two Kanji color‐word items as either within‐field or across‐fields. Viewers had to match the two items in terms of ink color (a color‐matching task) or word meaning (a name‐matching task). Each Kanji color word was presented with the same (congruent) or different (incongruent) ink color relative to the word meaning. Our results were twofold. First, a within‐field advantage appeared in the relatively easier color‐matching task, whereas an across‐field advantage tended to occur in the relatively harder name‐matching task. Second, in the word‐matching task an across‐field advantage appeared when both Kanji color words appeared in similar processing manners (both congruent or both incongruent), whereas a within‐field advantage occurred when processing of two Kanji items differed (one congruent and one incongruent). These results suggested that a shift toward a within‐hemisphere advantage occurs when two items are processed in respectively different ways.
