在教育心理学发展了百余年之后,脑研究以认知神经科学的形式,重新回到她的怀抱。认知神经科学对教育心理学的影响,主要体现在能力、学习和教学上;对这两个领域的关系,应采用开放而谨慎态度,以促进各自研究的科学发展。 相似文献

本研究从认知神经心理学的角度,根据有关语言产生和词汇认知的理论,对一例脑损伤病人的命名障碍进行了较为细致的个案分析,研究表明:(1)命名障碍可分为语义性和非语义性两类;(2)病人LY的命名无能主要不是因为其语义系统受到损害,而是因为其语音提取受到损害,以致于恰当的语义激活不能激活恰当的语音表征;(3)LY在汉字阅读中的表现也表明了字形信息在词义激活中的重要性。 相似文献

20世纪90年代以来,从认知神经科学的角度揭示语言及其它认知的脑机制成为科学研究的前沿与热点。研究各种脑损伤导致的特异性语言障碍,为探索语言和其它认知的结构、加工,及大脑不同部位在语言和其它认知活动中的功能增添了一条新的途径。同时也对临床失语症的诊断与康复起了很多积极的作用。汉语在世界语言体系中具有其独特性,对汉语的语言障碍及其脑机制的研究将为完善人类语义知识理论、语言的表征与加工模型有重要贡献,也为发展汉语失语症针对性的康复方案提供理论和实践基础 相似文献

认知神经心理学为探讨语言心理表征和加工理论提供了新途径 ,使得人们对心理词典结构的认识不断深入细化。研究表明词汇不同性质的信息在表征上相互独立 ,词典系统至少包括语义系统、语音输入词典与语音输出词典、字形输入词典与字形输出词典等模块。本文着重介绍了这一词典系统及其认知神经心理学证据 相似文献

该文介绍了词语产出的加工阶段以及在获得性语言障碍病人(失语症病人)身上这些阶段可能的损伤情况。文中特别介绍了两例词汇提取障碍病人的治疗,这不仅有助于了解该障碍,更有助于了解其潜在的理论问题。第一个案例关注使用不同的任务治疗词汇提取障碍,评估治疗效果,探究任务产生作用的原理。第二个案例使用词汇提取障碍的治疗方法探讨一个充满争议的问题:同音词(如,pour/paw)在词汇产出过程中是共用一个语音表征还是各自单独表征 相似文献

具身认知强调了心智或认知对身体及其感觉运动系统的依赖性。与传统认知心理学的符号加工模式不同的是, 它认为身体的构造和状态、身体的物理属性及其大脑与身体的特殊感觉—运动通道对认知具有塑造作用。认知既是具身的, 也是嵌入的, 大脑嵌入身体、身体嵌入环境, 构成了一体的认知系统。最初, 具身认知仅仅是一种反对笛卡尔身心二元论的哲学思潮, 经由认知科学哲学和理论心理学而逐渐进入了实验领域。具身认知研究充分利用了神经科学的方法和技术、数据和结论, 但是它并不主张把心理还原为生理或物理, 同时, 具身认知的神经科学取向仅仅给传统心理研究提供一个认识心智的新视角, 其目标并非取消行为水平的心理研究, 因此不会损害心理学的独立地位。 相似文献

认知心理学一般以正常人为研究对象进行人类认知过程的探讨 ,但由于正常人的心理过程的自动化程度高、加工速度快、影响因素多 ,使得许多重要的心理表征与加工很难更深入准确地加以研究。自 19世纪以来 ,人们相继发现不同脑组织受损的患者会表现出形式有别的心理加工障碍 ,尤其是一些障碍仅表现在某一 (或某些 )具体细小的加工环节上。例如 ,在临床上 ,一些脑损伤患者经常出现命名障碍 ,他们一般表现为命名物体或图形时困难 ,出现大量错误。然而 ,他们损伤的认知水平可能是不同的。研究发现 ,如果损伤在语义环节 ,病人在命名图片时出现语义… 相似文献

从认知神经科学面临的三个挑战--(1)神经科学是“还原” 的,不能完全解释一个人的心理活动过程;(2)认知神经科学无法真正解释人的心理与行为;(3)认知神经科学只能揭示出神经事件与认知活动或行为活动的相关性--入手来讨论其心理学理论价值,阐明认知神经科学在心理学研究中的重要地位及主流趋势。同时指出,认知神经科学只是心理学学科门类中的一种,它能解决的问题也只限于特定的范围,对它要有科学理性的认识和定位。 相似文献

A computational theory of hemispheric asymmetries in perception (double filtering by frequency) is described. Its central tenet is that the cerebral hemispheres first perform symmetric filtering of visual and auditory information. Functional hemispheric asymmetry arises from a second filtering stage (containing filters skewed in different directions in the two hemispheres). The first stage selects a range of task-relevant spatial or auditory frequencies from the absolute values. This range is passed to the asymmetric filters. In this way, the hemispheric difference becomes one of relative rather than absolute information. Behavioral deficits due to unilateral lesions in neurological patients and neuroimaging and electrophysiological measures in normal subjects implicate posterior cortex in these hemispheric differences. 相似文献

ABSTRACT— Research into the cognitive neuroscience of aging has revealed exciting and unexpected changes to the brain over the lifespan. However, studies have mostly been conducted on Western populations, raising doubts about the universality of age-related changes. Cross-cultural investigation of aging provides a window into the stability of changes with age due to neurobiology, as well as into the flexibility of aging due to life experiences that impact cognition. Behavioral findings suggest that different cultures process distinct aspects of information and employ diverse information-processing strategies. The study of aging allows us to identify those age-related neural changes that persist across cultures as well as the changes that are driven by culture-specific life experiences. 相似文献

ABSTRACT— Some organisms learn to calculate, accumulate knowledge, and communicate in ways that others do not. What factors determine which intellectual abilities a particular species or individual can easily acquire? I propose that cognitive-skill learning capacity reflects (a) the availability of specialized cortical circuits, (b) the flexibility with which cortical activity is coordinated, and (c) the customizability of cortical networks. This framework can potentially account for differences in learning capacity across species, individuals, and developmental stages. Understanding the mechanisms that constrain cognitive plasticity is fundamental to developing new technologies and educational practices that maximize intellectual advancements. 相似文献

The purpose of this paper is to examine the dual-process information-processing model of Schneider and Shiffrin (Schneider, W., and Shiffrin, R. M., Psychol. Rev.
84: 1–66, 1977; see also Shiffrin, R. M., and Schneider, W. Psychol. Rev. 84: 127–190, 1977) in light of the research data that have accumulated since the model was introduced more than 20 years ago. First, a brief introduction of the basic model of automatic and controlled information processing will be given. Second, some alternatives to the basic model that were developed over the last two decades will be reviewed. Third, data from neuropsychology and cognitive neuroscience that have a bearing upon this framework will be considered. Finally, some comments on the current usefulness of the dual-process framework for neuropsychological research will be offered. 相似文献

Knowledge about cognitive late effects in survivors of childhood acute lymphoblastic leukemia (ALL) is largely based on standardized neuropsychological measures and parent reports. To examine whether cognitive neuroscience paradigms provided additional insights into neurocognitive and behavioral late effects in ALL survivors, we assessed cognition and behavior using a selection of cognitive neuroscience tasks and standardized measures probing domains previously demonstrated to be affected by chemotherapy. 130 ALL survivors and 158 control subjects, between 8 and 18 years old at time of testing, completed the n-back (working memory) and stop-signal (response inhibition) tasks. ALL survivors also completed standardized measures of intelligence (Wechsler Intelligence Scales [WISC-IV]), motor skills (Grooved Pegboard), math abilities (WIAT-III), and executive functions (Delis–Kaplan Executive Function System). Parents completed behavioral measures of executive functions (Behavior Rating Inventory of Executive Function [BRIEF]) and attention (Conners-3). ALL survivors exhibited deficiencies in working memory and response inhibition compared with controls. ALL survivors also exhibited deficits on WISC-IV working memory and processing speed, Grooved Pegboard, WIAT-III addition and subtraction fluency, and numerical operations, as well as DKEFS number-letter switching. Parent reports suggested more attention deficits (Conners-3) and behavioral difficulties (BRIEF) in ALL survivors compared with referenced norms. Low correspondence between standardized and experimental measures of working memory and response inhibition was noted. The use of cognitive neuroscience paradigms complements our understanding of the cognitive deficits evident after treatment of ALL. These measures could further delineate cognitive processes involved in neurocognitive late effects, providing opportunities to explore their underlying mechanisms. 相似文献

Concepts from the history of neuroscience and neuropsychology are introduced as a background to current research findings with emphasis on the neuropsychology of memory. The author thinks that psychoanalysis should be interested in this research, but is critical of establishing a new discipline, the so-called neuropsychoanalysis. 相似文献

This study examined similarities and differences in the cognitive profiles of older adult instrumental musicians and non-musicians. We compared neuropsychological test scores among older adult non-musicians, low-activity musicians (<10 years of lessons), and high-activity musicians (≥10 years of lessons), controlling for self-reported physical and social activity, years of education, and overall health. Significant differences among groups were found on tasks of visual spatial ability, naming, and executive functioning. No significant differences were found on tests of attention/processing speed, or episodic memory. The current study supports late life cognitive benefits of early musical training, but only in select cognitive domains, including language, executive functioning, and visual spatial ability. The results are discussed in the context of cognitive reserve and aging. 相似文献

The main steps in the development of neuropsychology in France are briefly reviewed, from the early contribution of Paul Broca (1861) up until the early 1990s. The current epistemological and institutional crises is analyzed with respect to some general factors inherent to the domain (e.g., disputes between the proponents of the psychological and biological dimensions) and to particular factors related to the French situation (e.g., retirement of prominent neuropsychologists). As regards clinical practice and research activities, the future will probably show some fractionation of goals and techniques prior to new synthesis.Died suddenly in March 1991. 相似文献
