3～6岁儿童对11种基本颜色命名和分类研究

对3~6岁儿童11种基本颜色的命名和分类进行了研究。结果表明:⑴汉语儿童对11种基本颜色的正确命名率随年龄增长而提高,顺序是白、黑、红、黄、绿、蓝、粉红、紫、橙、灰和棕。(2)汉语儿童对基本颜色分类能力随年龄增长而提高。3~4岁儿童对基本颜色没有明确的分类标准。5岁儿童有了一定标准,并出现按“彩色/非彩色”和“冷色/暖色”分类的倾向。6岁儿童颜色分类标准更明确,开始由主观标准向客观标准转变。     

特征和位置信息在价值驱动注意捕获中的作用

本研究采用训练−测试范式考察颜色和位置信息在价值驱动注意捕获中的作用。实验1考察是否存在基于具体位置的价值驱动的注意捕获效应。在训练阶段, 被试对8个位置中两个位置出现的红色目标反应伴随着高奖励反馈, 而对另外两个位置出现的红色目标反应伴随着低奖励反馈, 其它4个位置为中性位置, 没有目标出现。在测试阶段, 一半试次中红色刺激作为分心物出现。结果发现, 只有当分心刺激出现在高奖励位置和两个高奖励位置之间的中性位置时才能够捕获注意; 实验2考察颜色和位置信息在价值驱动注意捕获中的交互作用。在训练阶段, 将颜色特征和位置信息联合起来进行学习。在测试阶段, 和高、低奖励相联结的颜色刺激各在1/3试次中作为分心物出现。结果发现, 只有当高奖励颜色出现在高奖励位置或出现在高奖励位置之间的中性位置时才能够捕获注意。研究结果表明：(1)位置联结的价值驱动的注意捕获效应能够泛化到特定邻近位置上; (2)个体在训练阶段将颜色和位置的联合特征与奖励建立联结, 训练阶段建立的联结不能泛化到部分特征上。价值驱动注意捕获效应的泛化具有选择性。     

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。     

Crystallizing enterprising interests among adolescents through a career development program: The role of personality and family background

This study evaluated the effectiveness of a new career development program designed to help adolescents explore their interest in enterprise as a career option. Using a person-oriented approach, pre- and post-test measurements of enterprising interests in an intervention (n = 321) and a control group (n = 302) of adolescents aged 16.5 years on average were compared. As predicted, the frequency of five different patterns of enterprising interest development (stable high, stable low, decreaser, increaser, middle) differed between the two groups, with increasers and decreasers more prevalent in the intervention group. Furthermore, a discriminant function analysis revealed that adolescents in the stable high and increaser groups showed the most entrepreneurial personality profile (e.g., low risk avoidance, high social dominance). Moreover, increasers often had a non-entrepreneurial family background. Results suggest that the new program is a useful tool in supporting adolescents’ exploration of enterprise as future career option.     

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.     

Forensic voice discrimination by lay listeners: The effect of speech type and background noise on performance

In forensic settings, lay (nonexpert) listeners may be required to compare voice samples for identity. In two experiments we investigated the effect of background noise and variations in speaking style on performance. In each trial, participants heard two recordings, responded whether the voices belonged to the same person, and provided a confidence rating. In Experiment 1, the first recording featured read speech and the second featured read or spontaneous speech. Both recordings were presented in quiet, or with background noise. Accuracy was highest when recordings featured the same speaking style. In Experiment 2, background noise either occurred in the first or second recording. Accuracy was higher when it occurred in the second. The overall results reveal that both speaking style and background noise can disrupt accuracy. Although there is a relationship between confidence and accuracy in all conditions, it is variable. The forensic implications of these findings are discussed.     

The influence of background music on learners with varying extraversion: Seductive detail or beneficial effect?

Seductive details in general affect learning and cognitive load negatively. However, especially background music as a seductive detail may also influence the learner's arousal, whose optimal level depends on the learner's extraversion. Therefore, the effects of extraversion and background music on learning outcomes, cognitive load, and arousal were investigated. We tested 167 high school students and found better transfer outcomes for the group with background music. They also reported higher germane load, but no impact of background music on extraneous cognitive load or arousal was found. In the group without background music, learners with higher extraversion reached better recall scores, which was not found in the group with background music. Results may cautiously be interpreted that there is a beneficial impact of background music that compensates for the disadvantages of low extraverted learners and which cannot be explained through arousal.     

A preregistered study of the relationship between childhood socioeconomic background,life history strategies and conformity

We conducted a high powered pre-registered study to investigate the relationship between childhood socioeconomic status, the adoption of different life history strategies and conformity. Contrary to our expectation we found no direct relationship between childhood socioeconomic background and conformity. However, we discovered a significant association between life history strategies and conformity. People who adopt fast (slow) life history strategies conform less (more) to social suggestions. Furthermore, we found a relationship between childhood socioeconomic background and life history strategies, with people from low (high) childhood socioeconomic backgrounds adopting fast (slow) life history strategies.     

背景音乐对消费者的影响：音乐契合度的视角

音乐契合度指的是背景音乐与广告、消费环境及商品特征等消费要素的契合程度。背景音乐与消费要素的契合可以体现在音乐特性、社会隐义和文化意蕴三个方面,这些契合程度能够对消费者的认知、情绪和行为等方面产生影响。若背景音乐的音乐特性与消费要素之间存在较高契合度,则能够提升消费者的注意效果、加强对商品的记忆并提升购买意图;背景音乐的社会隐义也能与消费要素产生契合关系,两者之间的契合程度决定了消费者对品牌的态度、情绪状态、对商品的记忆和选择;背景音乐与消费要素在文化意蕴方面的高度契合则能够促进消费者对品牌的态度、提升购买意愿、促进购买行为。未来研究应探索背景音乐更多的结构属性,进一步挖掘背景音乐影响消费者的边界条件,突破现有理论探索更深入的理论机制,并进一步探索音乐契合对于消费者认知和情绪的影响效应及其影响机制。
