Time and Its Relationship to Development in the Life Course: Some Reflections from a Study of HIV-Positive Adults

Although adult development is commonly understood as change over time, the relationship between time and development is rarely highlighted in research in the field. This paper first reviews 3 dimensions of time that interact in the study of developmental processes in the life course. The 3 dimensions are historical time; chronological age or life time; and social time, the culturally-specific, systematic ordering of life events. Second, the paper utilizes data from a follow-up study of HIV-positive men and women to illustrate the importance of time in development. In the original study, an HIV-positive diagnosis was viewed as a death sentence and had the effect of suspending the normal developmental patterns of adult life. Two years later, with the advent of protease inhibitors—an event in historical time—participants had reengaged with life time, once again making social time a relevant factor in their development. These data demonstrate how a better understanding of adult development can be achieved when historical time, life time, and social time are moved center stage in the study of developmental processes.     

Slowing Down the Clock: A Review of Experimental Studies Investigating Psychological Time Dilation

A review of 24 experiments investigated the factors that produce a subjective time dilation. The aim of this review was to investigate the magnitude of the obtained time dilation. The mean time duration judgment ratio of subjective time to objective time for the selected studies was 1.31, SD = .24. The analyses revealed that experimental studies investigating subjective time dilation tend to obtain small to moderate time dilation and that several factors can be manipulated in order to make a specific time interval appear longer than it is. Highlighting the factors that lead to a subjective time dilation has both research implications, by pointing to the underlying cognitive mechanisms of time perception, and practical implications, by indicating the factors that can be manipulated in order to control how we perceive time.     

Effects of time uncertainty and instructed muscle tension on fractionated reaction time

Abstract: An experiment was conducted to examine the effects of time uncertainty and instructed muscle tension on the reaction time of elbow flexion. Twenty-two right-handed subjects were asked to respond to an audio stimulus by flexing their right elbow under four conditions (2 time uncertainty × 2 instructed muscle tension). Electromyograms (EMGs) were recorded from the biceps and triceps on the subject's right side. Reaction time was divided into premotor time and motor time, based on the difference between the EMG and elbow flexion response. Analysis of reaction time showed that the effects of time uncertainty and instructed muscle tension were additive. Time uncertainty affected premotor time only, and instructed muscle tension affected motor time only. These results are discussed in terms of the assumption that premotor time is a reflection of the central nervous system and motor time is a reflection to the peripheral muscle system.     

论时间洞察力

时间洞察力既是能力特质也是动力特质,是个体对时间的认知、体验和行动(或行动倾向)的人格特质,它可以区分为过去时间洞察力、现在时间洞察力、未来时间洞察力,也可以区分为特质时间洞察力和状态时间洞察力。时间洞察力是决定个人事业与人生成功的关键因素。我们已开始用多维度-多方法对时间洞察力开展深入的研究。     

The Word “Time”—Voce “Tempo”

This article looks at the prevalent view of time in the history of Western philosophy and science and then contrasts it with the emerging new vision of time as ontologically constructive. Throughout Western history, philosophers and scientists attempted to marginalize and anesthetize the role of time by prioritizing being over becoming. But beginning with the Darwinian revolution in biology, the West could no longer deny the constructive role of time in bringing forth new ontological orders. While the 20th century witnessed the split between the reversible time of physics and the developmental time of biology, the time has now come for this divide to be reconciled. Twenty-first century science is already revealing the constructive role of time in cosmology with the likelihood of multiple universes. In conclusion, the authors speculate that our moment in human cultural development is ripe for a complex, multidimensional, and transdisciplinary understanding of time.     

军校学员时间管理倾向与学业成绩的相关研究

本研究采用时间管理倾向(TMD)问卷对265名军校学员进行测试,并与其上学期各门考试课程的平均成绩进行相关分析。结果表明,军校学员的时间管理倾向与其学业成绩存在显著正相关,时间监控观和时间效能感与学业成绩的相关也很显著,但时间价值感对学业成绩的影响并不明显。同时,高时间管理倾向者的学业成绩明显高于低时间管理倾向者。由此本研究认为,时间管理倾向可能是影响军校学员学业成绩的一个重要因素。     

驾驶员的动态反应时研究

本研究应用DFY-1型动态反应时测试仪,以解放CA10B 型卡车为实验用车,结合日常运输任务,对三种年龄组(20—29岁、30—39岁、40—49岁)的30名驾驶员,在三种车速(静态,30公里/小时及50公里/小时)条件下的反应时、动作时及制动反应时进行了测试。结果表明:车速对驾驶员的反应时及制动反应时有显著影响,而对动作时则无显著影响;驾驶员的年龄对反应时、动作时及制动反应时均无显著影响.本研究结果为加强驾驶员的安全教育与管理,控制车速提供了佐证。更高车速条件下驾驶员的反应时特点尚待进一步研究。     

时间隐喻对时距判断的影响作用

本研究考查了反映不同时速的时间隐喻句对时距判断的影响,结果发现时间隐喻表征对时距判断有导向功能,即将移动速度慢的喻体投射于时间时会带来对时距判断的高估,而将移动速度快的喻体投射于时间时会造成对时距判断的低估,这一结果表明语言也会是影响时距判断的因素之一,从而进一步佐证了时间认知的综合观。     

输出方式和输出时间对数字广度的影响

实验目的是探讨在不同的输出方式下,输出时间对短时记忆的影响是否相同。在数字广度实验中,给被试呈现单个数字组成的数字串,要求被试分别采用口头和书写两种输出方式来报告不同的内容：直接报告刺激呈现的单个数字串,以及在每个数字前附加不同长度的字符报告。结果发现附加字符使口头和书写的输出时间都增加。但在口头报告中,输出时间增加的同时伴随着记忆成绩下降,而书写报告的记忆成绩不受影响。讨论了此结果的意义,推测输出阶段中影响记忆成绩的可能是发音时间,而不是延迟时间。     

论个人的时间管理倾向

时间管理倾向是一种具有动力性的人格特征,它由时间价值感、时间监控观和时间效能感构成。善于管理时间者的生活质量是高的。时间管理技能可以通过训练得到提高。     

时间感知差异对跨期选择倾向的影响作用

本研究从人格特质差异角度出发, 采用简单跨期选择任务考察了由时距复制任务筛选的两类时距估计倾向不同的群体(时间高估者和时间低估者)在跨期选择中行为倾向的差异, 旨在探讨时间感知在跨期决策中的影响作用。结果发现：(1)无论任务难易, 与时间低估者相比, 时间高估者在跨期选择时更倾向于选择即时兑现的较小奖赏。(2)时间高估者和低估者的跨期选择反应时没有明显的差异, 但二者的反应时受任务难度的影响程度明显不同, 时间高估者的跨期选择反应时不受任务难度的影响, 而时间低估者在任务困难时的反应时比任务容易时明显增长。这些结果表明, 在跨期选择过程中, 时间感知倾向差异明显地影响了个体的选择倾向。时间高估倾向个体对时距的高估可能会导致其在跨期选择权衡中对收益成本的高估, 进而做出冲动的选择行为。     

大学生实时距、空时距估计的比较研究

本研究采用2(空时距、实时距)×8(1秒～8秒)的实验设计,以224名大学生为被试,考察了不同类型、不同长度的时距估计特点,结果发现;(1)时距类型在时距估计中存在主效应,在本实验中,1秒～8秒条件下实时距估计比空时距准确;(2)时距长度在时距估计中存在主效应,时距估计所产生的误差随时距长度的增加而增大;(3)时距类型与时距长度之间存在交互作用,对实时距、空时距估计进行曲线估计及预测,发现两类时距估计呈现动态特征,1845052秒之前实时距估计比空时距准确,之后空时距估计比实时距准确,两类时距估计曲线的变化速度也呈交替上升趋势。     

时间感知在跨期决策中的作用——时间决策模型的新探索

“时间”是跨期决策的“必需品”, 人们感知到的延迟时间决定跨期决策的结果。近年来, 研究者发现“时间长度感知”、“时间资源感知”和“时间框架感知”是时间感知作用于跨期决策的主要方式。时间感知的神经作用机制包含微观层面和宏观层面两种。“对数/指数时间折扣模型”、“感知时间基础模型”及“多模态漂移扩散模型”解释了时间感知的作用方式。然而, 现有理论模型还存在诸多局限, 主要包括“长短时距预测偏差”和“实际决策与预期决策偏差”两个方面。因此, 深入探讨时间感知影响跨期决策的基本方式, 分析现有理论模型的局限性并提出整合的机制框架具有十分重要的意义。未来研究亟需进一步整合时间感知的理论模型, 开展脑机制与应用方面的研究, 从深层揭露时间感知的作用本质, 帮助个人与社会更理性地决策。     

Psychopathic personality traits and temporal perspective: A test of the short time horizon hypothesis

A number of authors have proposed that psychopathic individuals possess an abnormally constricted time horizon (i.e., foreshortened sense of the future). This hypothesis was tested among 101 undergraduates, who were administered a battery of (1) self-report indices of psychopathic personality traits, antisocial behavior, and normal-range personality traits; (2) self-report indices of time perspective; (3) projective tests of time perspective; and (4) laboratory tasks assessing time estimation and capacity for foresight and impulse control. Measures of psychopathy/antisocial behavior tended to be negatively correlated with several self-report indices assessing preoccupation with the future and with a projective task assessing the frequency of thoughts concerning future events, although only one of the correlations with this latter task was significant. In most cases these correlations were not attributable to the variance shared by measures of psychopathy/antisocial behavior and measures of (low) anxiety-proneness, although several correlations decreased substantially after levels of harmavoidance were controlled. In contrast, measures of psychopathy/antisocial behavior were negligibly correlated with laboratory tasks. These results provide mixed support for the short time horizon hypothesis and suggest that further attention to the role of method factors in investigations of future time perspective is warranted.     

Prospective and retrospective time perception are related to mental time travel: Evidence from Alzheimer’s disease

Unlike prospective time perception paradigms, in which participants are aware that they have to estimate forthcoming time, little is known about retrospective time perception in normal aging and Alzheimer’s disease (AD). Our paper addresses this shortcoming by comparing prospective and retrospective time estimation in younger adults, older adults, and AD patients. In four prospective tasks (lasting 30 s, 60 s, 90 s, or 120 s) participants were asked to read a series of numbers and to provide a verbal estimation of the reading time. In four other retrospective tasks, they were not informed about time judgment until they were asked to provide a verbal estimation of four elapsed time intervals (lasting 30 s, 60 s, 90 s, or 120 s). AD participants gave shorter verbal time estimations than older adults and younger participants did, suggesting that time is perceived to pass quickly in these patients. For all participants, the duration of the retrospective tasks was underestimated as compared to the prospective tasks and both estimations were shorter than the real time interval. Prospective time estimation was further correlated with mental time travel, as measured with the Remember/Know paradigm. Mental time travel was even higher correlated with retrospective time estimation. Our findings shed light on the relationship between time perception and the ability to mentally project oneself into time, two skills contributing to human memory functioning. Finally, time perception deficits, as observed in AD patients, can be interpreted in terms of dramatic changes occurring in frontal lobes and hippocampus.     

时间定价与主观时间流逝速度感对利他行为的影响

采用筛选图片时间任务作为被试利他意愿的指标,考察在两种主观时间流逝速度（时间飞逝和时间缓慢）条件下,被试（时间定价组和非时间定价组）对利他行为的影响。结果发现,非时间定价组在时间飞逝和缓慢条件下利他行为差异不显著,但是时间定价组在时间飞逝条件下比在时间缓慢条件下利他行为时间明显较短。结果表明,时间定价组在时间飞逝条件下充分显现时间的价值,减少利他时间,而在时间缓慢条件下,在可接受的时间成本范围内,被试表现出较为乐于助人,证实了主观时间流逝速度会对个体利他行为产生影响。     

不同时间限制下小学儿童学习时间分配决策水平的发展

采用3×3二因素混合实验设计,利用计算机呈现刺激并记录被试的反应,以语意联系密切程度不同的词对作为难易不同的材料,借助线索回忆作为提取方式,利用四项研究分别探查小学儿童在短时限、中等时限和无时限三种时间限制下,学习时间分配的发展特点和趋势。得到如下结论：（1）小学各阶段儿童在学习过程中,主动进行了学习时间分配的决策。（2）儿童学习时间分配的决策水平随年龄增长而提高。（3）不同的时间限制难度不同,儿童在不同的难度任务下选择了不同的掌握标准,进行了不同的时间分配,支持了“标准影响分配假说”。（4）随着年龄增长,儿童的提取正确率有增加的趋势,时限越长,提取正确率越高。     

Perceptual and motor components of performance in three different reaction time experiments

Three reaction time experiments were conducted to examine the effects of time of day, stimulus intensity, stimulus modality, and constant and variable foreperiod on the perceptual and motor components of performance. These variables are all supposed to generate changes in arousal level. All the independent variables affected the perceptual component, while the motor component was significantly influenced only by foreperiod and modality. The results are discussed in relation to aspects of dependency/independency of the perceptual and motor components of human performance in reaction time experiments.     

儿童时间认知研究范式：困境与超越

西方实证主义导引下的儿童时间认知研究范式在取得丰硕成果的同时也渐入困境。以四种常见范式为突破口凝炼,困境是：(1)钟表时间认知范式能否涵盖儿童时间认知的全部内容;(2)各范式的使用与不同时间思维间能否有效适配;(3)共同量值系统(common magnitude system, CMS)能否从行为层面为儿童时间认知作出根源性解释;(4)在暂未发现成人时间认知特定脑机制的前提下,儿童时间认知脑机制的探索有多大的必要性与可行性等。诸困境折射出学界对儿童“经验”、“线性”时间的斜重;对“观念”、“周期性”时间的慢轻。中国时文化讲求以时间统摄空、物、人四者为一体,未来研究可将儿童时间认知归置于“时间-事件”背景之中,从具身情境、人际互动、时间言语习得与行为管控等方面超越。
