解释水平对品牌联想和品牌延伸评估的影响

由于人们更加关切与其解释水平相匹配的信息、经验和事物, 解释水平能够系统性地影响人们的判断与决策。本研究将解释水平视为重要的调节变量, 探查它对消费者的品牌联想和品牌延伸评估的可能影响。实验一用于检验来源于个体差异的不同解释水平(高与低)的被试, 对于同一品牌是否产生不同形态(原型性与范例性)的品牌联想以及探查它们之间的相对数量关系。实验二采用2(解释水平：高vs.低)×2(契合类型：原型性契合vs.范例性契合)组内和组间因子混合设计, 用于检验基于时间距离的解释水平是否调节契合类型对品牌延伸评估的影响关系。实验研究结果发现：在接触到品牌名称时, 具有高水平解释倾向的消费者, 将比低水平解释倾向的消费者, 呈现更多的原型性联想; 而具有低水平解释倾向的消费者, 将比高水平解释倾向的消费者, 呈现更多的范例性联想; 在低水平解释条件下, 消费者对范例性契合延伸产品的评估要好于对原型性契合延伸产品的评估; 而在高水平解释条件下, 消费者对原型性契合延伸产品的评估要好于对范例性契合延伸产品的评估。

A Distributed Representation of Temporal Context

The principles of recency and contiguity are two cornerstones of the theoretical and empirical analysis of human memory. Recency has been alternatively explained by mechanisms of decay, displacement, and retroactive interference. Another account of recency is based on the idea of variable context (Estes, 1955; Mensink & Raaijmakers, 1989). Such notions are typically cast in terms of a randomly fluctuating population of elements reflective of subtle changes in the environment or in the subjects' mental state. This random context view has recently been incorporated into distributed and neural network memory models (Murdock, 1997; Murdock, Smith, & Bai, 2001). Here we propose an alternative model. Rather than being driven by random fluctuations, this formulation, the temporal context model (TCM), uses retrieval of prior contextual states to drive contextual drift. In TCM, retrieved context is an inherently asymmetric retrieval cue. This allows the model to provide a principled explanation of the widespread advantage for forward recalls in free and serial recall. Modeling data from single-trial free recall, we demonstrate that TCM can simultaneously explain recency and contiguity effects across time scales.     

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.     

LEARNING TO TIME: A PERSPECTIVE

In the last decades, researchers have proposed a large number of theoretical models of timing. These models make different assumptions concerning how animals learn to time events and how such learning is represented in memory. However, few studies have examined these different assumptions either empirically or conceptually. For knowledge to accumulate, variation in theoretical models must be accompanied by selection of models and model ideas. To that end, we review two timing models, Scalar Expectancy Theory (SET), the dominant model in the field, and the Learning‐to‐Time (LeT) model, one of the few models dealing explicitly with learning. In the first part of this article, we describe how each model works in prototypical concurrent and retrospective timing tasks, identify their structural similarities, and classify their differences concerning temporal learning and memory. In the second part, we review a series of studies that examined these differences and conclude that both the memory structure postulated by SET and the state dynamics postulated by LeT are probably incorrect. In the third part, we propose a hybrid model that may improve on its parents. The hybrid model accounts for the typical findings in fixed‐interval schedules, the peak procedure, mixed fixed interval schedules, simple and double temporal bisection, and temporal generalization tasks. In the fourth and last part, we identify seven challenges that any timing model must meet.     

时序知觉重复启动效应的作用机制

先前研究发现,时序判断任务在启动的靶刺激先出现时出现了重复启动效应的反转,这是以往的理论所不能单独解释的。通过两个实验对我们提出的双加工表征匹配调节假说加以实证检验,实验结果支持了该假说。因此,双加工表征匹配调节假说能较完整地综合解释时序知觉重复启动效应的作用机制     

风险决策任务中时间距离对框架效应的影响

通过考察中国大学生时间距离的认知相关性,并进而探讨时间距离对风险决策任务加工方式及框架效应的影响.实验一通过问卷调查发现,与发生时间相对较远的事件相比,相对较近的事件,其认知相关性更大,验证了时间距离的认知相关性假设.在此基础上,以时间距离为自变量,设计小同的风险决策任务,考察框架效应发生的可能性(实验二、实验三).结果显示,时间距离近时,框架效应不明显;时间距离远时,框架效应明显.其原因是,发生在相对不远的将来事件引起分析加工模式,导致框架效应的减弱;发生在相对远的将来事件引起整体加工模式,导致框架效应的增强.

边界促进空间导航的认知神经机制

边界是指在人的视野中占据较大比例,且具有立体拓展平面的障碍物,对于人类和动物的空间导航行为具有极大的促进作用。认知发展研究发现儿童早期(1岁半～2岁)通过加工边界的空间几何结构实现物体定位,并且随着年龄的发展逐渐学会利用边界的高度信息(3.1岁～4.7岁)、长度信息(4～5岁)、视觉阻碍性信息(5岁)等完成空间导航。基于这些认知过程,神经影像学研究主要以成人为研究被试,发现大脑中的内侧颞叶和顶叶脑区在边界加工中有着不同功能作用。具体而言,边界的空间几何结构及构成要素(高度、长度和角度)体位置的学习和提取则由海马负责。但是,仍存在一些研究问题值得未来深入S探c讨i。e第n一c,e拓展深化边界促进与后顶叶之间的功能交互。第三,密切关注大脑对场地边界与场地中心编码的心理或神经表征的区别和联系。第四,重点考察阿尔兹海默症有关基因易感人群在基于边界导航的行为受损情况。最后,延伸探讨边界在长时记忆、时间知觉、视觉空间、社交网络等领域的影响机制。     

Integration and segregation of prior outcomes in risky decisions

Two experiments were conducted to test if a prior outcome influences the likelihood to accept a current gamble. Undergraduate students participating as subjects imagined that they on a fictitious betting day at a horse-race track did not gamble in the prior race, that they gambled and won, or that they gambled and lost. Subjects rated in one session the likelihood of gambling in the current race. In another session they rated how satisfied they would be with not gambling, with winning, and with losing, respectively. The results of Experiment 1 showed that as compared to no prior outcome the ratings of likelihood of gambling increased after a gain and decreased after a loss. This was explained by the assumption, supported by the ratings of satisfaction, that the prior outcome only affected the satisfaction with the expected loss of the current choice, making it less negative after a gain and more negative after a loss. These results were replicated in Experiment 2. In addition, if subjects did not know with certainty the outcome of a previous choice to gamble, the likelihood to accept the current gamble and the ratings of the satisfaction with its expected outcomes were largely unaffected.
