恒河猴对50以下数目的估计

本研究有６个从易到难的程序,每个程序有标准数目和比较数目,都是白卡片上的黑圆点。每次试验先呈现标准数目作为样本,强化后撤去,随后同时呈现标准数目和比较数目,令动物作二择一反应。实验结果表明,影响恒河猴数目估计的有两个主要因素,即标准数目和比较数目之间的数间距和这两个数目本身的大小。在数间距为４或大于４时,恒河猴能对５０以下的数作出估计;在数间距为２时,恒河猴能对９－２５的数作出估计,但不能对２７－４９的数作估计。作者以为,这里所进行的是一种相对的区域性的数目估计,但它仍然是一种数标签的过程。     

先前知识和样例设计对学习分数乘法规则的影响

研究通过3个实验,以6年级学生为被试,考察了先前知识在分数乘法规则单、双内容样例学习中的作用以及“标记法”、“标记+注释法”样例设计方法对低先前知识学生学习双内容样例的促进效果。结果发现：（1）高先前知识学生学习两种样例的迁移成绩无显著差异,且均好于低先前知识学生的成绩;（2）低先前知识学生学习单内容样例的迁移成绩明显优于双内容样例;（3）与学习普通样例相比,低先前知识学生学习“标记法”双内容样例的后测成绩无显著差异,但学习“标记+注释法”设计的样例的成绩明显更好。结果表明,学生单、双内容样例的学习效果受其先前知识水平的影响;低先前知识学生未能从“标记法”设计的双内容样例中获益,但学习“标记+注释法”设计的样例效果更佳。     

Utopias and Comparative Assessments of Justice

When we make public policy choices, is it helpful to know how utopia (that is, the perfectly just institutional design) would look? Amartya Sen argues that it is neither necessary, nor sufficient, nor even contributory. He claims that before making a policy choice one should compare several feasible institutional designs to see which promotes justice most (a “comparative assessment” of justice), and that it is misleading to use the perfect design as a standard in those comparisons. Principles of justice are the proper standard. The present article contends that the perfect design has nevertheless an important role to play in the prior task of identifying and refining our principles of justice. It also shows that the perfect design—in at least one sense of this term—may be a legitimate long‐term goal for present policy choices.     

Mixed interpretations of sales proposal signals

Long-term relationships with customers are critical determinants of a sales organization’s success. However, research tends to assess relational approaches from the salesperson or sales organization’s perspective and often neglects to capture customers’ perspectives which lead to the evaluative success or failure of buyer–seller relationships. This study assesses the seller’s bid-related signals from the buyer’s perspective following their selection or rejection of a business-to-business sales proposal. The authors adopt a theories-in-use approach, utilizing 54 depth-interviews with decision-makers from 33 buyer organizations. Within this data set, findings reveal three bid signals that are represented across both selection and rejection outcomes (i.e. mixed interpretations by buyers). These signals are the seller’s usage of price concessions, sales proposal specificity, and comparative customer examples. To better understand the mechanisms which influence buyers’ mixed interpretations of these signals, the authors utilize the newly-advanced qualitative pivoting technique to identify contextual variables across cases that influence the buyer’s positive or negative signal interpretation.     

Arbitrarily applicable comparative relations: experimental evidence for a relational operant

Arbitrarily applicable derived relational responding has been argued by relational frame theorists to be a form of operant behavior. The present study examined this idea with 4 female participants, ages 4 to 5 years old, who could not perform a series of problem-solving tasks involving arbitrary more than and less than relations. In a combined multiple baseline (across responses and participants) and multiple probe design (with trained and untrained stimuli), it was shown that reinforced multiple-exemplar training facilitated the development of arbitrary comparative relations, and that these skills generalized not just across stimuli but also across trial types. The sequence of training identified potential prerequisites in the development of comparative relations (e.g., nonarbitrary comparative relations). Taken as a whole, the present data, along with previous work by others in this area, suggest that relating arbitrary events comparatively is an operant. The implications of this conclusion for the analysis of complex behavior are discussed.     

消费者满意度测量中的光环效应

以中国铁路客运服务为研究对象,采用问卷调查的方法,证实了在消费满意度实际测量中光环效应存在的客观性,并验证了消费者满意度测量中同样存在总体印象和显著维度两种光环效应。进一步研究发现,无论上述哪种类型光环效应,其影响都是通过对满意度直接影响较大的维度进行传递;因此,企业在改进消费者满意度时,完全可以利用光环效应,通过改进显著维度来弥补其他维度的不足。     

消费者一定偏爱“笑脸”吗?产品外观中的表情元素对消费者的影响

表情是产品拟人化外观设计中重要元素。产品正面或负面的拟人化“表情” (表达正面或负面情感的表情)会影响到消费者对产品的感知。人际交往相关理论验证了正面表情对消费者的积极影响, 并认为负面表情不利于消费者与产品的互动。但是在现实市场中我们却看到, 消费者有时却更喜爱展现负面表情的产品, 营销领域的产品拟人化研究鲜有关注到产品表情的错位影响。具体而言, 在拟人化营销研究领域, 以下三个研究问题尚待探讨: 产品表情有怎样的具体体现及市场效用; 产品表情对消费者行为和态度影响的心理机制为何; 以及来自于消费者特质和产品因素的调节效应。回答以上问题能够进一步拓展和丰富营销领域的拟人化理论, 同时也将从实践上为产品外观设计提供建议和指导。     

The Multidimensional Model of Broaching Behavior

The multidimensional model of broaching behavior (MMBB) is introduced as a heuristic that addresses multicultural counseling and social justice competence. The MMBB includes humanistic skills that allow counselors to broach clients’ racial, ethnic, and cultural (REC) concerns in an effort to develop strong therapeutic alliances and alleviate distress. This article provides illustrative examples of the 4 MMBB dimensions: intracounseling, intraindividual, intra-REC, and inter-REC. Implications for the counseling profession and practice are described, and directions for future research are presented.     

A constructive Christian theology for the pluralistic world: Author's introduction of the project and a response to reviewers

The author of the five-volume a Christian theology for the pluralistic world (Eerdmans, 2013–2017), Veli-Matti Kärkkäinen, introduces the nature, distinctive features, and methodology of the project and also responds to the reviewers whose reviews have been included in this issue.     

行为决策中模糊规避研究的回顾与展望

模糊规避是指在相同奖赏的情况下,决策者会偏好有精确概率的事件而不是从主观上判断具有相同模糊概率的事件。自从Ellsberg提出模糊规避的概念以来,模糊规避已在行为决策研究的多个领域得到广泛验证。本文梳理了近五十年来关于模糊规避的研究文献,系统分析了模糊规避的研究范式、心理机制和影响因素,同时提出了未来的研究展望。
