学习材料的背景颜色对认知负荷及学习的影响

本研究采用2×2的多因素混合实验设计,探讨了物理学习环境之一的学习材料背景颜色对认知负荷及学习的影响。结果发现：（1）背景颜色在对认知负荷的影响上与任务类型产生交互作用,在解决创造性问题时,暖色调（如红色）背景下的认知负荷显著高于冷色调（如蓝色）。（2）从学习成绩上看,暖色调（如红色）更有利于记忆测试问题的解决,冷色调（如蓝色）更有利于创造性问题的解决。（3）认知负荷与任务绩效呈一定程度相关。     

背景颜色对一致性序列效应的调节

为满足迅速变化的环境要求,个体需要快速灵活地调整认知加工策略。背景颜色是一个重要的环境因素,它能够影响人的认知和行为表现。然而,背景颜色对认知控制在线调整的影响,是一个关键但又被忽略的问题。为解决这个问题,本研究采用字母flanker任务,考察了灰色、蓝色和红色背景条件下的一致性序列效应。结果发现,蓝色背景下的一致性序列效应不显著,而灰色和红色背景下得到了显著的一致性序列效应;此外,在这三种颜色背景下,flanker干扰效应无显著差异。这些结果说明,蓝色背景影响一致性序列效应,但干扰效应不受背景颜色的调节。当前的研究首次揭示了背景颜色对认知控制在线调整的影响,也进一步加深了我们对一致性序列效应的理解。     

The Political Color Line in America: Many “Peoples of Color” or Black Exceptionalism?

Despite the successes of the civil rights movement, a largely impermeable color line continues to restrict African Americans from assimilation into the broader American society. In the meantime high rates of immigration have produced an increasingly culturally diverse population. A "people of color" hypothesis suggests that the color line the new immigrants face resembles that imposed on African Americans. A "black exceptionalism" hypothesis suggests instead that the color line will be more porous for them, allowing for greater assimilation over successive generations, including a gradual weakening of politicized racial and ethnic group consciousness. Using data from Los Angeles County Social Surveys, we find that the largest new immigrant group, Latinos, like blacks, show strongly group-interested policy preferences and strong group consciousness. However, both effects are stronger for recent Latino immigrants than for the U.S.-born. We conclude that the new immigrant groups are increasingly likely to assimilate politically into the broader society in future generations, whereas a rather strict color line will continue to restrict blacks and maintain their distinctiveness.     

Iki and Contingency: A Reconstruction of Shūzō Kuki’s Early Aesthetic theory

Iki is the key word of Shūzō Kuki’s The Structure of Iki, and it became one of the most widely recognized Japanese aesthetic categories mainly due to this work. However, in The Problems of Contingency, which is Kuki’s most important philosophical work, there is no discussion of iki again, and consequently, most commentators of Kuki fail to see the correlation between his theories of iki and contingency. This article, by contrast, intends to provide a new interpretation of iki in the light of Kuki’s theory of contingency. The specific thesis of this paper is that aesthetic phenomena categorized as subject to the principles of iki are positively evaluated in Japanese culture just because the consciousness of iki is just one form of the consciousness of contingency, in which the awareness of alternatives to the actual situation could produce considerable spiritual entertainment for aesthetic subjects.     

Can a twelve-week intervention reduce barriers to bicycling among overweight adults in low-income Latino and Black communities?

This pilot study summarizes perceived barriers to bicycling among overweight adults in two low-income communities of color and evaluates the impact of a bicycling intervention on these perceived barriers. A randomized controlled trial with 38 total participants from one predominantly Latino and one predominantly Black neighborhood in Milwaukee, Wisconsin was conducted during summer 2015. The twelve-week intervention consisted of group bicycle rides and bicycling instruction. Several barriers identified prior to the intervention declined significantly among intervention group members soon after it was completed: not feeling healthy enough to bike, being physically uncomfortable while biking, not having a bicycle to use, not having other people to bicycle with, not knowing the best routes to use, not feeling safe from crime, not feeling safe from car traffic, and worrying that neighbors do not think it is normal for an adult to ride a bike. Eight weeks after completion, the intervention group reported significantly greater reductions than the control group with respect to the barriers of not feeling healthy enough to bike and not feeling safe from car traffic. In addition to decreasing barriers, qualitative analysis suggested that increasing support from family and friends as well as emphasizing personal health benefits could help motivate people to bicycle.     

Do Preschoolers Recognize The Emotional Expressiveness of Colors in Realistic and Abstract Art Paintings?

The present study was designed to examine preschoolers' ability to recognize the emotional expressiveness of an art painting, through its colors. To attain this aim 78 children, 3–5 years old were presented with realistic and abstract paintings conveying either happiness or sadness and were asked to choose those which matched the appropriate emotion. In total 16 paintings were used, which varied in color, while their subject matter was held as constant as possible after they had been previously rated by a group of adults to ensure that they conveyed the two emotions under investigation. Results showed that children's ability to recognize the emotional expressiveness of a painting through its colors appears at 3 years old and increases significantly at 4 and 5 years old. It was also found that the mood of happiness was more easily recognized than that of sadness, while the style of art paintings (realistic vs. abstract) did not affect children's ability to recognize emotions.     

Failure to Replicate the Increased Temporal Resolution Induced by Images That Give Impression of Danger

Kobayashi and Ichikawa (2016) recently reported that briefly presented images with dangerous impressions were detected with higher accuracy than images with safe impressions and concluded that the emotion evoked by such images improves temporal resolution of visual perception. In this study, we assessed confounding effects of the color saturations of the images used in their study. While attempting to replicate their results, we found the opposite results—that is, images with safe impressions were detected with higher accuracy than those with dangerous impressions. This likely reflected an observed correlation between color saturations and detection thresholds. To confirm the effects of color saturations, in subsequent experiments, we independently examined the effects of emotion and of color characteristics. We concluded that the previously reported increased temporal resolution was due to the confounding effect of color saturation, and not by the evoked emotion.     

双重作业的颜色编码方式对作业绩效的影响

研究探讨了不同颜色编码方式对双重任务操作绩效的影响。实验结果证明：若采用同类颜色编码方式,同时操作的两种作业就会产生结构限制,降低双重任务操作绩效;相反,若采用异常颜色编码方式,将有效地减少双重任务操作的结构限制,使双重任务的操作绩效得到提高。     

汉语常用颜色词的概念结构

采用自然分类和多维标度的方法,研究了汉语常用颜色词的概念结构。结果表明,汉语常用颜色词的语义空间具有按原型分布的特点。常用颜色词的概念结构有3个维度:1.彩色/非彩色;2.暖色/冷色;3.颜色的互补和对比。整个研究表明,颜色认知既受光波的物理属性和人眼的生物特性影响,又受语言和社会文化影响。     

LPN新／旧效应与汉字颜色来源提取的关联

已有研究表明,前额皮层在诸多种类来源的提取任务中起着重要作用,但不同记忆内容的来源提取研究存在不同的结果。为探索与汉字颜色来源提取相关联的头皮时空分布特征,本研究运用与Cycowicz等人(2001,2003,2005)相似的研究范式,以汉语名词作为实验材料,研究了颜色来源提取新/旧效应的头皮时空分布特征。结果显示,汉语名词在650~950ms存在与Cycowicz等人图形研究中相似的颜色来源提取的LPN新/旧效应。该结果表明,汉字的颜色来源提取与非言语材料一样,也与LPN新/旧效应相关联。
