The Training Effect of Working Memory Based on Central Executive System Intervention in Older Adults: A Randomized Controlled Study

This article aims to investigate the training effect of working memory in older adults. A total of 43 older adults ranging in age from 75 to 95 were recruited to participate in the study. A battery of tests regarding central executive function, working memory, and primary mental ability were administered in the pretest phase. A total of 22 of the older participants were randomly selected as the intervention group. Thirteen days after the pretest, the same tests were administered to all of the participants. The results showed that (1) the differences in the pretest and posttest gains in the task-switching tests were not significant between the intervention group and the control group; (2) the performance of the intervention group on the operation working memory span test and the graphical reasoning test showed a significant improvement after the intervention compared with the control group who did not receive the intervention. We can conclude that the working memory of old adults may be improved by an intervention targeting the central executive system. However, this possibility needs further investigation.     

主体的复归与现象学的先验转向

现象学的先验转向是由意义自在转向先验主体,由完全悬置自我到复归主体,这一方面是由于观念自在论的种种困难所促成,另一方面主体主义哲学惟有通过先验转向才能克服其主观性悖论,先验观念论是主体主义哲学最后和最高的形式,而这种最高形式中也隐藏着先验主体的一些理论困难。     

执行功能研究方法评述

虽然对执行功能的研究长期以来都是从神经心理学角度出发的,但现在发展心理学领域中也出现了大量的研究,其研究方法也层出不穷。该文从发展心理学角度分析了研究儿童冷执行功能和热执行功能的常用方法,包括搜寻任务、规则运用任务、优势规则抑制任务、矛盾冲突任务、问题解决任务、图片工作记忆任务、心理理论任务、延迟满足任务、儿童博弈任务和反向择物。通过对这些方法的分析,作者发现,执行功能的概念已逐步扩展到包容整个认知过程,而已有的关于执行功能的观点都只强调了其中某一个或几个方面,还没有一种观点能够将上述方法所研究的执行功能概括完整。执行功能的本质还远远不能清晰地展示在我们面前。     

认知主义与联结主义之比较

认知主义的研究定向和联结主义的研究定向是广义的现代认知心理学的两种主要研究范式。这两种研究范式都各有自己的研究内容和方法论,也取得了各自不同的成就,同时也存在各自不同的问题。通过对两种研究范式的比较,我们可以清楚地认识到二者的相互沟通和融合才是认知心理学未来发展的必然趋势。     

The role of retrieval mode and retrieval orientation in retrieval practice: insights from comparing recognition memory testing formats and restudying

The effectiveness of retrieval practice for aiding long-term memory, referred to as the testing effect, has been widely demonstrated. However, the specific neurocognitive mechanisms underlying this phenomenon remain unclear. In the present study, we sought to explore the role of pre-retrieval processes at initial testing on later recognition performance by using event-related potentials (ERPs). Subjects studied two lists of words (Chinese characters) and then performed a recognition task or a source memory task, or restudied the word lists. At the end of the experiment, subjects received a final recognition test based on the remember–know paradigm. Behaviorally, initial testing (active retrieval) enhanced memory retention relative to restudying (passive retrieval). The retrieval mode at initial testing was indexed by more positive-going ERPs for unstudied items in the active-retrieval tasks than in passive retrieval from 300 to 900 ms. Follow-up analyses showed that the magnitude of the early ERP retrieval mode effect (300–500 ms) was predictive of the behavioral testing effect later on. In addition, the ERPs for correctly rejected new items during initial testing differed between the two active-retrieval tasks from 500 to 900 ms, and this ERP retrieval orientation effect predicted differential behavioral testing gains between the two active-retrieval conditions. Our findings confirm that initial testing promotes later retrieval relative to restudying, and they further suggest that adopting pre-retrieval processing in the forms of retrieval mode and retrieval orientation might contribute to these memory enhancements.     

预期想象对拖延的影响:想象过程和想象结果的效应分离

摘要 为了考察预期想象对不同拖延水平个体拖延行为的影响,本研究采用一般拖延量表(General Procrastination Scale)选取高拖延被试和低拖延被试,要求被试在进行模拟现实的拖延任务之前分别对任务过程和任务结果进行预期想象,比较不同拖延水平的被试在预期想象作用下拖延行为的变化。结果表明：(1)在两组被试中,相比于无想象条件下的拖延行为,对任务过程的预期想象增强拖延行为,对任务结果的预期想象削弱拖延行为;(2)对任务不同成分的预期想象所引发的情绪与拖延行为的变化相关显著。这说明情绪和预期想象是影响拖延的重要因素,合理地操纵对任务不同成分的预期想象可以有效干预拖延行为。     

民间信仰:和谐社会的文化资本

和谐社会建设不仅是一项社会工程,也是一项文化工程。作为社会建设的基础工程,文化建设既要坚持中国先进文化的方向,又要弘扬民族优秀文化传统,充分开发与艺术利用本土文化库藏的和谐理念与和谐精神,为和谐社会建设提供文化资本支持。民间信仰是民族文化的重要组成部分,也是和谐社会建设重要的本土文化资本。(1)其以精神信仰的方式建构了平民百姓安身立命、顺道达和的和谐心理,从而为社会和谐创造了心理基础;(2)其所书写的忠孝节义、积德行善等道德故事,为民间社会整齐风俗提供了道德文本;(3)其全民性的"大乐与天地同和"的仪式庆典也成为民间社会文化整合的重要文化纽带;(4)其艺术语言的和谐风格滋养了民间社会的和谐性灵及日常生活;(5)其泛灵崇拜神化了天人关系,成为乡土社会人物和谐的生态哲学。     

运气均等主义理论:证成与反对

运气均等主义理论是当今平等理论争论的焦点问题之一.人们关于运气均等主义的争论可以分为"外部之争"和"内部之争"两个方面:运气均等主义的外部之争是争论运气均等主义本身"能否证成"的问题,而运气均等主义的内部之争是在认同运气均等主义基本信条的前提下,争论应该以"什么的平等"来体现它.实际上,就平等理论关注的对象而言,运气均等主义错置了关注的重心,与平等主义政治运动相脱节,已经走进了死胡同.运气均等主义要实现自我救赎,应扩大其关注的范围.     

不同车速下司机对交通标志的辨认距离实验

本实验所得数据表明,不同车速下司机对同一标志的判读距离是不一样的,车速愈高,司机能判读标志的距离就愈短,同步行时相比,在车速提高到100公里/小时时,司机对标志的判读距离可减低35～45％。据我们的补充实验,这种现象的产生可能是由于司机在高速驾车情况下所产生的生理心理负荷造成的。     

咀嚼口香糖对认知及情绪的影响
