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。     

Recognition of color-form compounds by 4-month-old infants

In two studies, a paired-comparison procedure was used to investigate whether 4-month-old infants can perceive and remember correlations of color and form. In Study 1, infants were shown simultaneous presentations of two different colored shapes until two criteria for familiarization had been met. They were then offered a simultaneous choice between a colored form that they had already seen and one that was a new combination of a familiar color and a familiar shape. The infants looked significantly longer at the new combination than at the familiar combination on the test trial. In Study 2, the same procedure was used, except that the familiarization criteria were less stringent and additional analyses of the infants' test trial behavior were conducted. Infants again exhibited a significant preference for the new combination, both when looking time accumulated during the entire test-trial was analyzed and when looking just up to the “first look away” was considered. These findings that 4-months-olds can perceive and remember compounds of visual attributes conflict with the results of several studies in which the habituation and test stimuli were presented sequentially rather than simultaneously. Differences in the nature of the information processing that may be evoked by the two methods are discussed.     

The Accessibility of Group Memberships

Abstract

The authors performed 2 experiments to examine the accessibility of thoughts about group memberships (i.e., collective self-cognitions) relative to thoughts about traits, states, and behaviors (i.e., private self-cognitions). Few collective self-cognitions were accessible for the present participants from an individualist culture. Furthermore, collective self-cognitions were highly associated with each other in a self-structure. The findings were interpreted in terms of the two-baskets theory that private and collective self-cognitions tend to be stored relatively separately in memory (D. Trafimow, H. C. Triandis, & S. G. Goto, 1991).     

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。

声符与义符在形声字识别中的影响机制

形声字是汉字的主体,声符和义符作为形声字的构字部件,其各自的功能属性对形声字的识别具有不同的影响。当前研究采用多种实验任务,结合眼动以及脑电等多种技术,对声符和义符各自的功能属性及作用机制进行了较为全面的研究,这为后续研究奠定了良好的基础,并对未来汉字认知领域的研究具有重要的启示作用。     

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。     

Products of modal logics and tensor products of modal algebras

One of natural combinations of Kripke complete modal logics is the product, an operation that has been extensively investigated over the last 15 years. In this paper we consider its analogue for arbitrary modal logics: to this end, we use product-like constructions on general frames and modal algebras. This operation was first introduced by Y. Hasimoto in 2000; however, his paper remained unnoticed until recently. In the present paper we quote some important Hasimoto's results, and reconstruct the product operation in an algebraic setting: the Boolean part of the resulting modal algebra is exactly the tensor product of original algebras (regarded as Boolean rings). Also, we propose a filtration technique for Kripke models based on tensor products and obtain some decidability results.     

Job characteristics: their relationship to job satisfaction,stress and depression

This study investigated the influences of job characteristics on job satisfaction, stress and depression among South African white collar workers. Participants were managers in full-time employment with large organisations. They completed the Job Diagnostic Survey, the Perceived Stress Scale and the Beck Depression Inventory. A regression approach was used to predict job satisfaction, stress and depression from job characteristics. Job characteristics (skill variety, task identity, task significance, autonomy and feedback) predicted job satisfaction, as well as stress and depression. Job characteristics are weak predictors of perceived stress and depression. Work related factors, such as interpersonal relations and organisational culture, may better predict mental health in work settings.
