Children's Evaluative Categories and Inductive Inferences within the Domain of Food

Evaluative categories include items that share the same value- laden assessment. Given that these categories have not been examined extensively within the child concepts literature, the present research explored evaluative categorization and induction within the domain of food as a test case. Specifically, two studies examined the categories of healthy and junky foods in children aged 4 and 7 years. Study 1 showed that by aged 4 years, children appropriately apply the evaluative categories of healthy and junky foods to a variety of different foods. Study 2 showed that by age 4 years, children also selectively use the evaluative categories of healthy and junky foods for inductive inferences about the human body, but not for arbitrary or unrelated inferences. Taken together, these results highlight the importance of evaluative processing in young children's categorization and induction.     

儿童特质推理与情绪和效价线索理解的关系

本研究从情绪、效价两个角度探讨儿童特质理解与线索理解的关系。372名4、5、7岁儿童完成了贴标签和行为预测两类特质推理任务。实验一显示,所有年龄段儿童都能完成对情绪性特质害羞和胆小的推理,且特质和行为评定与情绪评定呈显著正相关;实验二显示,所有年龄段均能完成双重性质特质助人为乐和自私的推理,特质和行为评定与效价、情绪评定均呈显著正相关,回归分析则只有效价评定进入方程。结果说明,儿童完成情绪性特质推理任务时与情绪理解能力关系密切,而对双重性质特质推理时更多的与效价理解能力有关。     

条件联结觉察在评价性条件反射中的作用

评价性条件反射(Evaluative Conditioning, EC)指通过将一个中性刺激和一个情绪性刺激重复配对, 使中性刺激获得情绪性刺激的情感性评价。条件联结觉察(Contingency Awareness)指被试觉察到中性刺激和情绪性刺激的配对规律。当前, 条件联结觉察在EC中的作用尚存争议。一些研究证明, 条件联结觉察独立于EC, 甚至阻碍了EC; 另一些研究则表明, 条件联结觉察促进EC的发生; 还有些研究发现条件联结觉察在EC中的作用受其他变量的调节。因此, 在将来的研究中, 需发展出更准确的觉察测量、检验其他变量的调节作用、加强多感觉通道的EC研究、探索EC的加工机制。     

The Role of Temperament in Children's Reliance on Others as Sources of Information

By 3 years of age, children generally have a firm understanding of others' reliability, but there is considerable variation among individual children. Little attention has been paid to factors that influence such individual differences. This study addressed this by assessing the relation between reliability understanding and temperament in children approaching their third birthday. We measured children's ability to judge a speaker's trustworthiness and to selectively learn new information from a reliable informant. Observer ratings provided assessments of children's activity, task orientation, and affect/extraversion. Significant associations between selective trust and the temperament dimension of affect/extraversion were found, along with associations between selective trust and gender and language ability. This indicates that the ability to ascertain whether a speaker is a reliable person from whom to learn is related to several individual child characteristics.

Types of Food Aversions: Animal,Vegetable, and Texture

Despite a growing body of research investigating the origins and effects of food aversions, few research instruments have been developed to measure aversions to specific types or categories of food. Undergraduates (N = 209) responded to a series of food aversion questionnaires. The results suggest that people tend to be averse to 2 types of foods (vegetables and meats or fats) and to the texture and taste of certain foods (e.g., oysters). Aversions were slightly more prevalent among women than among men and were correlated with lower educational levels. The authors provide a means of advancing future research on this problem by reliably identifying 3 categories of food aversions. Future researchers should evaluate additional food categories and expand the focus on food aversions beyond the current concern with learned avoidance of specific food items.     

评价性条件反射效应：无条件刺激的呈现时长、效价强度与关联意识的作用

以真实商标图案为条件刺激, 情绪图片为无条件刺激, 探索无条件刺激呈现时长、效价强度与关联意识对评价性条件反射效应的影响。实验通过结合四图再认测验与基于项目分析, 对关联意识的作用进行了详细探讨。结果表明, 评价性条件反射效应只发生在无条件刺激长呈现水平与无条件刺激强效价水平; 评价性条件反射效应的产生需要基于被试的关联意识。关联意识在呈现时长(效价强度)与评价性条件反射效应间的中介作用不显著。结果不支持评价性条件反射的内隐错误归因机制及联想-命题评价模型的相关论断, 部分支持命题性解释模型。     

阈下启动的心理机制初探

本研究以汉语双字名词为材料、正确率和反应时为指标,进行了阈下启动的实验探索。揭示出（1）当启动词在前面的练习中被归类时,阚下语义启动显著表现出来,在练习中形成的阈下启动联接是词汇和语义范畴之间的;（2）练习中被归类的词在后续的不同按键反应任务中作为阈下启动词均发生作用,阈下启动是启动的无意识归类,而不仅仅是自动化的刺激-反应模式。

The Effect of Counterconditioning on Evaluative Responses and Harm Expectancy in a Fear Conditioning Paradigm

In fear conditioning, extinction targets harm expectancy as well as the fear response, but it often fails to eradicate the negative affective value that is associated with the conditioned stimulus. In the present study, we examined whether counterconditioning can serve to reduce evaluative responses within fear conditioning. The sample consisted of 70 nonselected students, 12 of whom were men. All participants received acquisition with human face stimuli as the conditioned stimuli and an unpleasant white noise as the unconditioned stimulus. After acquisition, one third of the sample was allocated to an extinction procedure. The other participants received counterconditioning with either a neutral stimulus (neutral tone) or a positive stimulus (baby laugh). Results showed that counterconditioning (with both neutral and positive stimuli), in contrast to extinction, successfully reduced evaluative responses. This effect was found on an indirect measure (affective priming task), but not on self-report. Counterconditioning with a positive stimulus also tended to enhance the reduction of conditioned skin conductance reactivity. The present data suggest that counterconditioning procedures might be a promising approach in diminishing evaluative learning and even expectancy learning in the context of fear conditioning.     

Extraversion and External Efficacy: The Moderating Role of Corruption

Perceptions of governmental responsiveness matter because of their influence on the willingness of citizens to participate in politics and thereby express their interests and hold policymakers accountable. Where do external efficacy attitudes emerge? In recent years, scholars have examined this question by turning to personality traits, especially extraversion. Extant studies reveal a positive relationship between extraversion and external efficacy, but thus far they have focused on high-income democracies. How consistent are findings across countries with varying levels of political and economic development? In my view, the answer depends on the level of corruption and its implications for external efficacy. Where low (high) levels of bribery and other forms of malfeasance enable (impede) public influence on governmental decision-making, greater levels of extraversion will increase (decrease) perceptions of governmental responsiveness. I test my hypothesis with three sources of nationally representative survey data that include countries from North America, Latin America, and the Caribbean. My results have implications for the quality of democracy.

Categories and Facets in Integrative Levels

Facets and general categories used in bibliographic classification have been based on a disciplinary organization of knowledge. However, facets and categories of phenomena independent from disciplines can be identified similarly. Phenomena can be classified according to a series of integrative levels (layers), which in turn can be grouped into the major strata of form, matter, life, mind, society and culture, agreeing with Nicolai Hartmann’s ontology. Unlike a layer, a stratum is not constituted of elements of the lower ones; rather, it represents the formal pattern of the lower ones, like the horse hoof represents the shape of the steppe. Bibliographic categories can now be seen in the light of level theory: some categories are truly general, while others only appear at a given level, being the realization of a general category in the specific context of the level: these are the facets of that level. In the notation of the Integrative Level Classification project, categories and facets are represented by digits, and displayed in a Web interface with the help of colours.     

熟悉性和兼容性对复合社会范畴刻板印象表征的影响

通过对启动任务范式的改进,运用3个实验全面考察了复合社会范畴本身的熟悉性和兼容性对复合社会范畴刻板印象中抽象表征和样例表征策略运用的影响。实验1分别以熟悉的、不熟悉且在刻板印象上不兼容的复合范畴为研究对象,研究发现对熟悉的复合范畴采用抽象表征,而对不熟悉且在刻板印象上不兼容的复合范畴的表征采用样例表征;实验2以熟悉且在刻板印象上不兼容的复合范畴为研究对象,研究发现对于熟悉但构成范畴不兼容的复合范畴的表征也采用样例表征;实验3采用相同的实验范式,在描述和定义两种启动任务中设置子范畴间兼容的刻板特质词和不兼容的刻板特质词,选择与实验2相同的复合范畴"男中学教师"为目标群体,更加严密地证实和整合了实验1与实验2的研究结论。3个实验的结果说明复合范畴刻板印象的表征关键取决于兼容性,一旦复合社会范畴的构成范畴在刻板印象上不兼容,那么对于这一复合社会范畴刻板印象的表征采用样例表征。当构成复合范畴的两个子范畴之间兼容时,熟悉性成为刻板印象运用抽象表征还是样例表征的影响因素,无论是对内群体的刻板印象还是外群体的刻板印象,对熟悉的刻板特质词的表征运用抽象表征。     

From Ode to Sport To Contemporary Aesthetic Categories of Sport: Strength Considered as an Aesthetic Category

The standpoint of this paper is the distinguished Ode to Sport from Pierre de Coubertin, specifically the second part of the elegy, the one concerning beauty. Starting with “O Sport, you are Beauty!”, Pierre de Coubertin mentions, beyond beauty, an assemblage of aesthetic categories such as sublime, abject, balance, proportion, harmony, rhythm and grace. He also mentions strength, power and suppleness. Although the first quoted categories are general categories of aesthetics, it seems quite relevant to emphasize the need of the author to introduce specific categories that fits to body movement and sport, such as strength, power and suppleness. There is no doubt that the first group of categories also fits to sport and body movement, but it equally fits to different forms of art, while strength, power and suppleness can only be literally applied to sport and performing arts.

The purpose of this paper is to analyze strength as an aesthetic category of sport, developing three main arguments: the feeling of achievement and its conservation, the fight against gravity and the multiple forms of strength’s expression.

It is concluded that strength can improve the communicative power of sport and its emotional appeal. In sports such as gymnastics, diving or synchronized swimming, the appreciation of strength exhibited by the athletes communicates to the observer some king of ease and lightness that enhances the aesthetic judgment. In other sports like weightlifting, sumo or rugby, effort and heaviness are stamped on the athlete's faces, what contributes to a sort of communion between the observer and the athlete that can also improve the aesthetic experience.

Categories and Levels of Reality

The discussion of the relation of levels of reality to categories is important because categories have often been interpreted as constituting levels of reality. This article explores whether this view is correct, and argues it is not. Categories as such should not be understood to constitute levels of reality, although particular categories may. The article begins with a discussion of levels of reality and then turns to specific questions about categories and how they are related to these levels.

Translating External Knowledge to Team Creativity in Turbulent Environments: The Role of Absorptive Capacity and Knowledge Integration

In seeking to understand factors contributing to team creativity in dynamic environments, we explored the role of external knowledge search on team creativity through absorptive capacity and knowledge integration. We tested our hypotheses with a sample of 96 teams involving 421 employees in China. Results demonstrated that external knowledge search related positively to team creativity, fully mediated by both absorptive capacity and knowledge integration. In addition, environmental dynamism played a moderating role in the relation between external knowledge search and absorptive capacity, as well as in the relation between external knowledge search and knowledge integration. We discussed the implications of these findings for research and practice.     

儿童归纳推理中的标签作用

传统的归纳推理观主要包括特征相似性观和概念观。在基于这两种传统观点的研究过程中,研究者逐渐发现类别知识,特别是标签起到的独特作用,但目前关于不同类型标签作用的分析还缺乏系统性。该文从分析目前两大主要标签研究现状——语言标签和类别标签入手,试图明确标签作用和关系、解释混淆和误解;同时,作者就以标签为载体的研究同儿童语言发展间存在的密切联系提出了儿童归纳推理发展的语言认知模式。文章最后认为未来的研究方向应集中在对机制、技术和深层次内部关系三方面问题的探讨上。
