知识背景对觉察配对词间语义联系的影响

研究探讨了生物领域知识丰富者和贫乏者判断来自生物领域或一般领域亲疏度不同的配对词间联系的差异。采用2（生物领域丰富者和贫乏者）×2（生物领域配对词和一般领域配对词）×2（语义关系疏远配对词和语义关系密切配对词）混合实验设计,要求被试尽快判断4种类型共120组配对词的两个词间是否存在语义上的联系。结果发现：生物领域知识丰富者比贫乏者更倾向于接受生物领域配对词间的联系,且在判断生物领域关系疏远配对词时花费更长时间;而两者在判断一般领域配对词间的联系时,无论在接受性或反应时上均不存在差异。这一结果说明,知识背景影响个体觉察特定范畴或特定领域中观念间联系的敏感性,觉察观念间联系的能力表现出领域特殊的特征。     

Relationship of Type of Product, Shopping Orientations, and Demographics with Preference for Shopping on the Internet

This research examines whether (1) consumers' shopping orientations are significantly related to their preference for shopping online, (2) consumers' demographic characteristics are significantly related to preference for shopping online, (3) relationships of shopping orientation and demographic variables with purchase preferences on the Internet will vary by the type of products (i.e., search, experience, or credence). Deriving from the product classification theory, products are classified into four categories: search products, two types of experience products, and credence products. Data were collected through self-administered surveys from adult population in two metropolitan areas in the Southern United States. The findings significantly support the study's hypotheses that shopping orientations such as convenience and recreational shopper and demographic variables such as gender, education, and household income were significantly related to consumer's online purchase preference. The researchers' findings also confirm that the relationships of shopping orientation and demographic variables with purchase preference for shopping online significantly differ by product category. More specifically, convenience and recreational orientations were positively related to preference for shopping online for experience-1, experience-2, and credence product types, though the directional relationship between recreational shopper orientation and preference for shopping on the Internet was positive rather than negative as hypothesized. The results and discussion section also includes implications drawn from the findings.     

Products of Modal Logics. Part 3: Products of Modal and Temporal Logics

In this paper we improve the results of [2] by proving the product f.m.p. for the product of minimal n-modal and minimal n-temporal logic. For this case we modify the finite depth method introduced in [1]. The main result is applied to identify new fragments of classical first-order logic and of the equational theory of relation algebras, that are decidable and have the finite model property.     

Thinking about product attributes: Investigating the role of unconscious valence processing in attribute framing

In the present investigation we conducted three studies to examine how unconscious valence processing influences participants' quality judgments in an attribute-framing task. In Studies 1 and 2 we observed how individuals who had depleted cognitive resources, through distraction (Study 2) and time constraint (Study 3), differed in their responses to an attribute-framing task. In Study 3 we subliminally primed participants with attribute frames and then presented them with a frameless decision task. Our results revealed that attribute framing arises from unconscious valence processing and conscious processing may only play a role when the frame is especially salient.     

Equivalents for a Quasivariety to be Generated by a Single Structure

We present some equivalent conditions for a quasivariety of structures to be generated by a single structure. The first such condition, called the embedding property was found by A.I. Mal′tsev in [6]. It says that if are nontrivial, then there exists such that A and B are embeddable into C. One of our equivalent conditions states that the set of quasi-identities valid in is closed under a certain Gentzen type rule which is due to J. Łoś and R. Suszko [5].

消费者新产品采纳的特征

成功的新产品开发是企业获取竞争优势的重要因素,但创新产品并非总能得到市场的接受,大多数的新产品扩散往往以失败告终。因此,业界和学界对新产品采纳问题进行了诸多探索。新产品采纳过程是指创新产品从被设计制造出来,到最终被消费者或潜在消费者认识和采用的过程。对相关研究综述发现：以Rogers创新扩散模型为依据,按采纳时间和特征的不同,新产品采纳者可以系统分为早期采纳者和晚期采纳者,二者之间主要从创新性、产品理解和易感性三个维度进行区分。具体来说,早期采纳者具有高创新性、高产品理解和低易感性;晚期采纳者具有低创新性、低产品理解和高易感性。在此基础上,我们探究了各维度下影响消费者新产品采纳的具体因素。未来研究可以从这三个维度出发,结合已有研究的不足以及当前环境、消费特点等进行拓展。     

中介效应的点估计和区间估计:乘积分布法、非参数Bootstrap和MCMC法

针对中介效应ab的抽样分布往往不是正态分布的问题,学者近年提出了三类无需对ab的抽样分布进行任何限制且适用于中、小样本的方法,包括乘积分布法、非参数Bootstrap和马尔科夫链蒙特卡罗(MCMC)方法.采用模拟技术比较了三类方法在中介效应分析中的表现.结果发现:1)有先验信息的MCMC方法的ab点估计最准确;2)有先验信息的MCMC方法的统计功效最高,但付出了低估第Ⅰ类错误率的代价,偏差校正的非参数百分位Bootstrap方法的统计功效其次,但付出了高估第Ⅰ类错误率的代价;3)有先验信息的MCMC方法的中介效应区间估计最准确.结果表明,当有先验信息时,推荐使用有先验信息的MCMC方法;当先验信息不可得时,推荐使用偏差校正的非参数百分位Bootstrap方法.     

“美男诱惑”真的奏效吗:男性代言女性产品对女性消费者产品评价的影响

男性代言女性产品的广告策略真的奏效吗?本文旨在探讨女性产品代言人性别与女性消费者对该产品评价之间的关系。4个实验的结果显示,与女性代言女性产品相比,男性代言时女性消费者对该产品的评价会显著降低。该影响是通过身份威胁感的中介实现的。此外,身份肯定对该效应存在调节作用。具体来讲,当被试受到女性身份肯定操控时,主效应会加强。本文实证研究了男性代言女性产品可能带来的负面效应,基于性别认同一致性理论拓展了产品性别属性的下游结果。

污染效应在消费者行为领域的表现及其心理机制

随着健康问题越来越受到消费者的重视, 学者们对污染效应的研究和兴趣也与日俱增, 特别是在消费者的感知和偏好方面。在消费者行为研究中, 污染效应是指消费者会降低对他人接触过产品的感知价值。本研究主要回顾了在消费行为中污染效应的定义和特性, 然后从接触因素、位置因素、产品因素和社会因素等方面来探讨污染效应的前因, 并进一步归纳了污染效应对消费者行为的消极影响和积极影响。最后, 探讨了污染效应的理论基础和边界条件。在此基础上, 对污染效应在消费者行为领域的未来研究方向进行了展望。
