中国人的时间知觉广度

时间知觉是社会结构和文化传统的映射,具有深刻的社会文化意涵。本文聚焦时间知觉广度这一概念,探讨中国人的时间知觉广度及其对自我连续性和社会变化观等心理过程的影响。通过综合讨论诸多实验发现提出,中国人具有较大的时间知觉广度,包括具有显著的过去取向和未来取向。较大的时间知觉广度提升了中国人跨时间的自我连续性,并且影响着中国人看待世事变化的变化观,这些特点又进一步影响到其它心理过程,例如对苦难和幸福的解读,在股票市场中的决策等。在一定程度上,这些特点可能是中国人在应对不确定性和重大危机时表现出更强的心理韧性和复原力的心理基础。本研究还指出中国人时间知觉广度具有独特的文化意义,包括整体性思维、过去现在未来互嵌互动和双向延展、与自我连续性和社会结构相关联以及具有道德属性等。基于此,本研究提出了时间知觉广度的文化心理比较模型,并分析了时间知觉广度对自我同一性和文化同一性的影响结果。希望本文能为进一步研究“中国人应对历史危机的心理特征与行为表现”提供科学依据。     

标量计时模型的影响因素及发展

标量计时模型为人类时间知觉的研究提供了理论框架和研究范式, 它采用信息加工的观点, 包含时钟、记忆和决策三个阶段。时间二分任务是在标量计时模型的框架下研究时间知觉和加工的理想范式。它要求被试对时距进行与标量计时模型相对应的多阶段操作, 包含了时间知觉所涉及的各个过程, 能有效测量主观时距和时间敏感性的变化。通过这个范式, 研究者发现, 除了任务参数, 年龄和疾病都会影响人的主观时距和/或时间敏感性。这些时间二分任务的实验结果促进了标量计时模型的发展, 最近提出的两阶段决策模型和差别模型分别以不同的方式对标量计时模型进行了修正, 并解释了参数设置的影响和计时的个体差异。     

时间期待的认知与神经机制

时间期待是指个体利用环境中的时间信息预测目标刺激何时出现的能力。相关的认知模型可以分为两类：一类侧重于解释时间期待的形成过程, 如痕迹条件反射模型、双加工模型、动态注意模型、时间定向理论等; 另一类侧重于解释时间期待的更新过程, 如策略模型和时间再定位模型等。不同类型的时间期待激活的脑区不同, 表明时间期待的产生和更新过程存在分离：期待的产生激活与运动有关的左侧脑区, 而期待的更新激活与控制有关的右侧脑区。     

音乐时间加工的影响因素

音乐的时间维度在音乐艺术中具有重要的作用。已有研究表明, 对音乐时间维度的加工受制于许多方面, 一方面, 音乐构成要素的特征影响着人们对音乐时间的加工; 另一方面, 听者的年龄、注意、工作记忆、音乐训练以及对音乐的熟悉性等因素也影响着他们对音乐时间加工的深度和广度。未来的研究应进一步确定音乐时间加工的影响因素及其相对重要性, 并对音乐时间加工中基因与环境的关系以及发展的敏感期等问题进行研究。     

乾坤二卦形上解

乾坤二卦体现了宇宙创化、生生之本,亦显示了中国人特有的时空观,这时空观与西方传统的时空观不同,而与现代科学思想不相违,且比现代科学思想更具深刻哲学之意涵.     

谁更愿意购买绿色产品？认识绿色消费者

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。     

网络词语与非网络词语的知觉差异:时间知觉、空间距离知觉与知觉范围

根据具身认知理论,人们的认知会受到身体活动的影响。网络环境下人的身体活动受到限制,因而其认知活动与非网络环境存在很大的差异。本研究目的在于考察人们对网络词语与非网络的日常词语的时间知觉,空间距离知觉与知觉范围是否有差异。结果发现被试对网络词语的时间知觉更长;网络词语的空间距离感与日常词语没有显著差异;在启动网络词语之后,被试的知觉范围缩小,对中心刺激的反应显著快于边缘刺激。本研究发现了网络词语加工在时间知觉和知觉范围上的变化。     

People Wait Longer when the Alternative is Risky: The Relation Between Preferences in Risky and Inter‐temporal Choice

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.

The organisation of spatial and temporal relations in memory

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.     

Future self-appraisals and global self-esteem: Who benefits more from thinking about the future,and why?

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.
