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.     

Luck and Risk

This paper advances new theses about the relationship between luck and risk, using recent work by Duncan Pritchard (2014, 2015, 2016) as its foil. Once Pritchard’s views are introduced in section 1 , the rest of the paper completes two different tasks, one critical and one constructive. By focussing on some epistemological cases that Pritchard’s model would fail to identify, section 2 shows that it relies on a difference that is in fact inessential: the one between the occurrence and the non‐occurrence of an event. Section 3 sketches and defends an alternative account of the luck/risk distinction, based on the consideration of situations (instead of events) from different temporal perspectives: luck assessments track a situation’s past, considering it the actual outcome of some previous event, whereas risk assessments look at the situation’s future, regarding it as the initial condition of some unsettled event.     

汉字字组时间顺序的内隐记忆研究

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。     

When causality shapes the experience of time: Evidence for temporal binding in young children

It is well established that the temporal proximity of two events is a fundamental cue to causality. Recent research with adults has shown that this relation is bidirectional: events that are believed to be causally related are perceived as occurring closer together in time—the so‐called temporal binding effect. Here, we examined the developmental origins of temporal binding. Participants predicted when an event that was either caused by a button press, or preceded by a non‐causal signal, would occur. We demonstrate for the first time that children as young as 4 years are susceptible to temporal binding. Binding occurred both when the button press was executed via intentional action, and when a machine caused it. These results suggest binding is a fundamental, early developing property of perception and grounded in causal knowledge.

发展性阅读障碍的视听时间敏感性缺陷及其脑神经机制

阅读是一个视听加工过程,阅读障碍的产生可能是过程中视听时间敏感性缺陷的结果。视听时间敏感性指个体对视觉和听觉刺激出现时间的感知能力,可通过同时性判断、时间顺序判断和视听整合考察。研究发现,阅读障碍者在这一能力上表现出行为和脑层面异常。而这些研究多是拼音文字背景,汉语文字下该领域研究相当少。未来需要丰富实验设计,扩大对汉语背景下视听时间敏感性研究,并以此开发干预手段,为阅读障碍的机制和治疗提供借鉴。     

时序知觉影响因素与思考

时序知觉是在几十毫秒到几百毫秒内, 对事件的同时性、非同时性和顺序性的知觉。对时序知觉的影响因素的探索可分为自下而上和自上而下两种研究取向。自下而上的研究探讨刺激的物理特征、被试的生物学特征, 以及实验方法对时序知觉的影响。而自上而下的研究探讨因果信念、情绪、文化对时序知觉的影响。今后的研究还应结合行为实验与神经科学技术, 深入探讨时序知觉的两种加工方式是分离的还是同时进行的, 以及揭示控制时序加工的脑区。     

敬畏对跨期选择的影响：时间洞察力和时距敏感度的作用

本研究考察了情绪(敬畏、愉悦和中性)对跨期选择的影响机制,以及时距敏感度和时间洞察力在其中的作用。结果显示：(1)相比中性,敬畏情绪下个体的折扣率更大;(2)相比中性,敬畏情绪下折扣率降幅更大;(3)对于未来取向者,敬畏情绪下折扣率比中性条件下更大;(4)对于现在取向者,敬畏情绪下折扣率降幅比中性条件下更大。结果表明,敬畏情绪通过未来时距的敏感度影响跨期选择偏好,使个体更加偏好延迟奖赏,同时,个体的时间取向在其中起调节作用。     

CS as an effect: action-based evaluative conditioning depends on temporal contiguity

ABSTRACT

In this study, we analysed Evaluative Conditioning (EC) with a recently introduced S-R paradigm [Blask et al., 2016 Blask, K. , Frings, C. , & Walther, E. (2016). Doing is for feeling. Journal of Experimental Psychology: General , 145 (10), 1263–1268. https://doi.org/ 10.1037/xge0000211 [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]. Doing is for feeling. Journal of Experimental Psychology: General, 145(10), 1263–1268], in which valence first transfers from an affective US to a response and then from this valence-laden response to a novel CS. Based on action control research, the CS in this procedure could be interpreted as an effect of the response. Hence, temporal contiguity of the valence-laden response and the CS should determine whether EC occurs. We tested this hypothesis in an experiment, in which we varied the time interval between the response and the subsequent CS. Results show that EC effects occurred only under conditions of high temporal contiguity thus supporting our assumptions. This finding sheds light on the processes underlying action-based EC in particular and evaluative learning in general.     

Inter-brain co-activations during mindfulness meditation. Implications for devotional and clinical settings

Mindfulness meditation usually takes place as personal, introspective activity. It is not known if this practice activates the brain differently when done alone or with someone else.Sixteen couples of expert meditators performed mindfulness-oriented meditation (MOM) and instructed mind-wandering (IMW) tasks in two conditions: once sitting in the same room (SR) and once in two different rooms (DR). Spontaneous electroencephalographic (EEG) data was collected during 7-minute recording sessions in the four experimental settings (MOM/SR, MOM/DR, IMW/SR, IMW/DR). Power in band was computed in separate clusters of independent components of the EEG signals.In addition to significant task effects, found in frontolimbic (MOM > IMW in gamma) and frontoparietal locations (MOM < IMW in theta), significant condition effects were found in frontal (SR > DR in delta) and in temporo-occipital regions (SR > DR in theta and alpha). Moreover, a significant interaction between task and condition revealed higher gamma activity in limbic areas during MOM/SR vs. MOM/DR settings. This effect was not attributable to gender, age nor the meditation expertise of participants.We thus show that the brains of two people work differently when they are doing something together or alone; some of these differences are specific to mindfulness meditation. Implications for devotional and clinical settings are discussed.
