消费者厌腻感的生成机理、诱发因素及缓解策略

厌腻感是指消费者对连续或过量消费同一产品或服务的效用感、享乐感或满意度下降, 负面感知逐步抑制正面感知的主观情绪体验。为缓解或防止厌腻感的产生, 消费者会采取品牌转换、多样化寻求、控制消费周期等行为, 因此厌腻感已成为企业或店铺培养顾客忠诚的主要障碍。国外文献分别从厌腻感的生成过程、功能反应、知觉状态和属性感知等方面, 划分厌腻类型; 剖析了厌腻感生成的享乐适应、边际效用递减、认知失调以及最佳刺激水平等理论原理及机理; 探讨了生理厌腻感和心理厌腻感生成的诱发因素及影响效应; 验证了外部因素和个体因素的调节作用; 同时探讨了消费者缓解或防止厌腻感的主要策略及行为反应。最后对现有文献的研究思路、特点和不足进行了评述, 提出了未来研究方向。     

Preconscious effects of temporary goals on attention

Two experiments examined whether accessible goals preconsciously direct selective attention. Goal activation was manipulated by one's goal pursuit being either undermined or affirmed (resulting in an experienced state of either incompleteness or completeness). Attention responses were assessed through a Stroop-like task (Experiment 1) and a response-time task in which participants indicated a stimulus' direction of motion (Experiment 2). Results showed that when goals were accessible, attention was drawn toward goal-relevant items—even when these items were to be ignored and when responses occurred too fast for conscious control. Accessible goals directed implicit cognition (i.e., attention toward stimuli associated with the goal), despite the fact that these goals were not chronically held, but manipulated in the lab.     

Candidate Vulnerability and Exposure to Counterattitudinal Information: Evidence From Two U.S. Presidential Elections

Politically motivated selective exposure has traditionally been understood through the lens of long‐standing attitudes and beliefs, but the role of environment in shaping information exposure practices merits further consideration. Citizens might respond to the political environment in their information‐seeking behavior for numerous reasons. Citizens who believe their position is politically vulnerable have specific cognitive and affective needs that may make them uniquely attuned to counterattitudinal information. In the context of a presidential election, this means that as the defeat of a supported candidate appears more likely, attention to counterattitudinal content will increase. Data collected in the 2008 and 2012 U.S. Presidential elections support this prediction, although this relationship was observed primarily among supporters of the Republican candidate in both elections.     

中文词汇加工中的饱和现象

长时间注视一个字或词语后,感觉这个字词变得奇怪且陌生,这种现象称为饱和现象。本研究采用快速类别/词汇匹配范式,考察中文词汇加工中的饱和现象。实验1-3发现单纯的语义或字形的重复均未能引发饱和,只有类别标签在字形和语义上的同时重复才引发饱和,表明与英文饱和相似,中文饱和发生在字形加工和语义加工的联结阶段。实验4结果表明,中文饱和还能够由表义部件的重复引发,体现了中文饱和的特殊性。     

Attentional processes and meditation

Visual attentional processing was examined in adult meditators and non-meditators on behavioral measures of change blindness, concentration, perspective-shifting, selective attention, and sustained inattentional blindness. Results showed that meditators (1) noticed more changes in flickering scenes and noticed them more quickly, (2) counted more accurately in a challenging concentration task, (3) identified a greater number of alternative perspectives in multiple perspectives images, and (4) showed less interference from invalid cues in a visual selective attention task, but (5) did not differ on a measure of sustained inattentional blindness. Together, results show that regular meditation is associated with more accurate, efficient, and flexible visual attentional processing across diverse tasks that have high face validity outside of the laboratory. Furthermore, effects were assessed in a context separate from actual meditation practice, suggesting that meditators’ better visual attention is not just immediate, but extends to contexts separate from meditation practice.     

锚定效应的产生前提及作用机制

为了探讨锚定效应的产生前提以及基础锚定效应的理论解释,设计了两个实验。实验一选取高、低、无三种锚值,设置了15ms、45ms、75ms、1000ms四种呈现时间,结果发现只有15ms条件下未出现锚定效应,随着呈现时间增加,锚定效应不断增大,低锚下的锚定效应高于高锚下的锚定效应。实验二设置了语意相同但表述形式不同的两种水平的锚值,结果发现两者引发的锚定效应不同。锚定效应的产生前提是注意,数字启动假说可以更好地解释基础锚定效应。     

The path or the goal? Decision vs. information focus in biased information seeking after preliminary decisions

Research on the phenomenon of selective exposure to information demonstrates that after preliminary or final decisions, people show a preference for supporting rather than conflicting information (confirmation bias). In this article, we examine conditions that increase or decrease distortions in the search for information. We report on four experiments indicating that the confirmation bias is influenced by whether people focus on their decision or on the presented pieces of information during the information search. Focusing on the decision, for example, because a reward for a correct decision is promised or simply because participants repeatedly think of it, increases the confirmation bias. On the other hand, if participants focus on the available pieces of information because they have to invest money in order to search for information or because they have to evaluate the individual pieces of information, the confirmation bias decreases. Implications for theoretical understanding and interventions for decision-making situations are discussed.     

Psychoticism and attentional flexibility

In three separate experiments, we tested the hypothesis that a systematic relationship between psychoticism (P) and visual selective attention is infrequently observed because the tasks typically used to test individual differences in efficiency of attentional mechanisms do not entail attentional flexibility. We manipulated the selection rule of the computerized divided visual attention (DIVA) task to be either (a) a predictable, or (b) a random manner, and a secondary task was added to check the quality of high P scorers’ performance in an interference condition; and we also introduced breaks between DIVA tasks to allow for cue utilization. Results revealed that low P scorers outperformed high P scorers in the regular selection rule alternation condition (cue utilization possible), whereas high P scorers performed better in random alternation condition – high P scorers also showed performance superiority in the dual task condition unless stimuli presentation was speeded up. Thus, P does not necessarily impair attentional performance; indeed, our data point to performance advantages of high P, especially attentional efficiency in tasks requiring small demands of attentional control.     

The moderating role of attitude strength in selective exposure to information

Individuals prefer to receive information that is consistent with their attitudes. Three experiments examined whether attitude strength moderates this selective exposure effect. Experiments 1A and 1B found that participants preferred attitudinally consistent information but that this effect was more pronounced to the extent that the attitude was strongly held. Experiment 2 replicated these findings and ruled out an alternative interpretation that a general tendency to hold strong attitudes rather than issue-specific attitude strength moderates selective exposure. Discussion concerns the implications of these findings and the possibility that other variables moderate the selective exposure effect.     

Interference by process, not content, determines semantic auditory distraction

Distraction by irrelevant background sound of visually-based cognitive tasks illustrates the vulnerability of attentional selectivity across modalities. Four experiments centred on auditory distraction during tests of memory for visually-presented semantic information. Meaningful irrelevant speech disrupted the free recall of semantic category-exemplars more than meaningless irrelevant sound (Experiment 1). This effect was exacerbated when the irrelevant speech was semantically related to the to-be-remembered material (Experiment 2). Importantly, however, these effects of meaningfulness and semantic relatedness were shown to arise only when instructions emphasized recall by category rather than by serial order (Experiments 3 and 4). The results favor a process-oriented, rather than a structural, approach to the breakdown of attentional selectivity and forgetting: performance is impaired by the similarity of process brought to bear on the relevant and irrelevant material, not the similarity in item content.
