绿色消费虽然备受关注但消费者积极性却不高,这可能和个体差异性有关。为了考察绿色消费的积极性,本研究从个体差异的视角出发,引入购买时间距离这一变量,以揭示面对绿色产品的矛盾性消费者究竟更愿现在购买还是将来,决策模式是否会存在个体差异。研究发现,时间距离调节绿色消费观与产品购买意愿的关系,而产品价值感知部分中介了该调节作用。具体来说,绿色消费者不会受到时间框定的影响,而非绿色消费者则表现出时间框定效应即更倾向于在将来而不是现在购买绿色产品;这是因为绿色消费观以自上而下的方式影响绿色消费者动机加工,使绿色产品的价值感知较为稳定,而非绿色消费者的价值感知则根据购买时间距离的不同而变化。研究结果说明在生态文明建设日益紧迫的当下培育个体绿色消费观具有重要的意义。 相似文献

People Wait Longer when the Alternative is Risky: The Relation Between Preferences in Risky and Inter‐temporal Choice 下载免费PDF全文
In two experiments, we demonstrate that despite indicating indifference when probed about risk or delay in isolation, when forced to explicitly trade‐off between the two, participants prefer delayed over risky rewards. This pattern of findings sets a boundary condition for any common utility‐based comparison process involving both risk and delay. Furthermore, this change from indifference‐in‐isolation to delay‐preference‐in‐a‐trade‐off strengthens as reward amount increases. Exploratory modeling results suggest that the shift in preference can be explained by allowing for different discount rates for delay‐only choices compared with when delay is in competition with risk. This explanation is better than one in which probability weighting is different between risk‐only choices and risks considered in the presence of a delay. Together, the empirical and modeling work lays a path for future investigations of why and when people's evaluation of the properties of risky and delayed choices vary as a function of the alternatives on offer.

Renante Rondina II Kaitlin Curtiss Jed A. Meltzer Morgan D. Barense Jennifer D. Ryan 《Memory (Hove, England)》2017,25(4):436-449
Episodic memories are comprised of details of “where” and “when”; spatial and temporal relations, respectively. However, evidence from behavioural, neuropsychological, and neuroimaging studies has provided mixed interpretations about how memories for spatial and temporal relations are organised—they may be hierarchical, fully interactive, or independent. In the current study, we examined the interaction of memory for spatial and temporal relations. Using explicit reports and eye-tracking, we assessed younger and older adults’ memory for spatial and temporal relations of objects that were presented singly across time in unique spatial locations. Explicit change detection of spatial relations was affected by a change in temporal relations, but explicit change detection of temporal relations was not affected by a change in spatial relations. Younger and older adults showed eye movement evidence of incidental memory for temporal relations, but only younger adults showed eye movement evidence of incidental memory for spatial relations. Together, these findings point towards a hierarchical organisation of relational memory. The implications of these findings are discussed in the context of the neural mechanisms that may support such a hierarchical organisation of memory. 相似文献

People tend to think positively about their future selves. However, it remains unclear to what extent this tendency depends on the positivity of their current self-appraisal. To study this problem, we employed the assumptions of construal level theory, the concept of self-enhancement, and the assumptions of temporal self-appraisal theory, and we examined the role of global self-esteem in the relationship between temporal distance and future self-appraisals measured in absolute (Study 1), comparative temporal (Study 2), or comparative social (Study 3) ways. In all three studies, when assessed in terms of specific dimensions, future self-appraisals increased with temporal distance only in people with low self-esteem, but when assessed in terms of general dimensions, self-appraisals were higher in the distant compared to the near future irrespective of self-esteem level. 相似文献

音乐句法是指将离散的音符元素组合成序列的规则。音乐句法加工受到音乐结构特征和听众自身特征两个方面的影响。针对每个方面,本文聚焦于近年来进展迅速的几个因素进行评述,分别是依存距离和音乐时间结构,听者的年龄和音乐训练程度。未来研究应进一步比较不同距离的句法加工,澄清音乐时间结构何时并且如何影响句法加工,考察音乐句法加工中遗传和环境的作用以及发展的敏感期,并对这些因素之间的共同影响展开研究。 相似文献

该研究对大学生时间自我透视与价值偏好之间的关系进行了探讨。结果发现,当从远期的时间距离来透视自我(可能自我知觉)时,个体更加偏好理想主义价值;当个体从近期的时间距离来透视自我(当前自我知觉)时,个体更加偏好实用主义价值。但是,时间自我透视与价值偏好之间并非遵循严格的线性关系。此外,研究还发现,上述规律只出现于个体对自我的知觉中,个体对他人的时间透视并未表现出类似的规律。 相似文献

We show that the variety of n-dimensional weakly higher order cylindric algebras, introduced in Németi [9], [8], is finitely axiomatizable when n > 2. Our result implies that in certain non-well-founded set theories the finitization problem of algebraic logic admits
a positive solution; and it shows that this variety is a good candidate for being the cylindric algebra theoretic counterpart
of Tarski’s quasi-projective relation algebras.

汉字字组时间顺序的内隐记忆研究 总被引:1,自引:1,他引:0
采用再认与偏好测验的内隐记忆方法,以文字相同而字序不同的三类汉字字组为刺激材料,对汉字字组进行启动效应的实验研究,探讨汉字字组内隐的时间顺序表征存在的可能性及其加工特点。结果表明:汉字字组中字与字之间存在内隐的时间顺序表征,这种内隐的时间顺序表征是对刺激项目知觉特征中时间维度的一种反映,受知觉表征系统支配,具有自动加工和提取的特点。 相似文献
