认知神经心理学简介

认知神经心理学是认知心理学的一个分支。它的目的是探讨当人们执行认知活动的时候,心理信息加工过程是怎样的,所采用的手段是研究这些认知功能受损的病人。它与认知神经科学的不同在于：认知神经心理学关注的是心理（mind）,而认知神经科学关注的是大脑（特别是关注与认知有关的大脑机制）。研究认知神经心理学的方法也可以用于研究发展性认知障碍,如阅读障碍,或者特殊的语言损伤,这就是发展性认知神经心理学。这些方法还可以用于高级认知发面的研究,如信念形成和心理理论。这些高级认知方面的障碍是精神病学的范畴,因此这类研究错觉、幻想或虚构等的认知神经心理学叫做认知神经精神病学。认知神经心理学的典型特征有：1）研究症状,而不是并发症;2）采用个案研究,而不是群体研究;3）主要数据来源是症状间的双分离;4）致力于模块化认知模型的建立。     

语言转换对非熟练双语者不同认知控制成分的即时影响

语言转换情境是否影响非熟练双语者的认知控制存在争议。实验1和实验2分别采用不同的实验范式探讨语言转换对非熟练双语者的认知控制是否会有即时的影响, 以及对不同认知控制成分的影响是否会有不同。结果表明, 语言转换情境能够即时地促进反应抑制, 阻碍干扰抑制, 但对认知灵活性没有影响, 同时说明了反应抑制、干扰抑制和认知灵活性属于3种不同的认知成分, 其内在作用机制不同。此外, 研究结果还进一步说明了双语者的认知控制优势是双语者长期双语使用的结果, 为双语优势的内在机制提供了实验支持。     

语言认知加工过程中的早期皮层电位

在一项通过事件相关电位的N400考察双语者的语义表征的实验研究中,我们偶然发现两个早期成分与语言语义和形式认知加工相关。一个是在140毫秒左右达到峰顶的负波(N140),另一个是在190毫秒左右达到峰顶的正波(PJ90)。前者反映了被试对语义的初级分类与评价的神经认知过程;后者则反映了对语言形态的加工过程。     

词汇表征和加工理论及其认知神经心理学证据

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     

第二语言水平对双语者语言抑制能力的影响——来自英语–汉语单通道双语者和英语–美国手语双通道双语者的证据

采用同形异义词干扰任务考察第二语言水平对英语–汉语单通道双语者和英语–美国手语双通道双语者语言抑制能力的影响。结果发现:(1)高水平英语–汉语单通道双语者的语言抑制能力较强,但低水平英语–汉语单通道双语者与英语单语者的语言抑制能力没有显著差异,说明少量的双语经验不足以导致双语认知优势;(2)不同水平的英语–美国手语双通道双语者的语言抑制能力差异不显著。所以如此,与英语–美国手语双通道双语者不存在口语和手语的双语表征加工竞争有关。整个研究表明,双语认知优势效应与双语者的二语水平以及通道经验有关。     

语言对认知的影响—— 基于双语认知“优势效应”的分析

双语认知优势效应不仅在言语领域有所表现, 更主要的体现在以认知控制、注意选择、心理抑制能力为基础的非言语认知领域。影响该效应出现的因素是多方面的, 第二语言获得年龄和双语熟练程度是其中两个最为重要的因素。研究发现, 双语表征和产生机制是导致双语认知优势效应的语言学机制, 而以Broca语言区为核心的大脑前额叶则是其主要的神经基础。未来该领域的研究不仅要进一步关注双语认知优势效应产生的内在言语机制和神经基础, 还应当积极关注双语认知和个体情绪、人格发展的关系。     

交流语言认知特征

交流是以语言为核心媒介的一种社会人际互动方式, 与个人语言认知过程不同, 交流互动性决定了交流语言认知过程的复杂性、灵活性。重点归纳和述评：交流语言内容特征、交流语言加工理论、交流语言与非语言因素的关系。未来对于交流语言认知特征的探讨应持一个相对开放的态度; 尝试采用多因素依次叠加的实验设计, 考虑交流实验情境的自然性, 以多种子加工过程为基础全面理解语言认知特征。     

语言转换影响双语认知优势的发展进程

本研究包括两部分,第一部分对双语转换问卷进行修订,用于客观测量双语者的语言转换能力;第二部分采用数字命名任务考察语言转换对双语认知优势发展进程的影响。结果发现,在低水平阶段,语言转换频率与转换消耗存在显著负相关;在高水平阶段,语言转换频率与转换消耗、混用消耗均存在显著负相关。结果说明,语言转换首先影响瞬时转换能力,积累一定的经验之后,才会对持续监控能力与抑制控制能力产生积极影响。本研究结果表明,双语认知优势效应的发展具有一定的顺序性。     

双语脑的研究:不同的语言是否有不同的皮层机制?

随着认知神经科学技术的发展,研究者对“不同语言是否有不同的大脑皮层机制?”这个问题的研究也进一步深入。一系列的神经心理学和脑成像研究表明,语言获得的时问、流利程度、获得方式等都可能成为影响语言的皮层机制的因素。     

汉语的认知神经心理学研究

认知神经心理学为探讨语言的心理机制开辟了一条新途径,使得人们对心理词典的认识日渐深入。该文着重介绍了汉语方面的认知神经心理学研究成果,其中包括语义系统、语音输出词典、语音输出buffer的信息表征方式,以及汉字的书写机制与阅读机制     

师生认知方式与藏族双语儿童学业成绩关系研究

以藏族双语儿童和任课教师为被试,采用北师大心理系编制的CSFT工具,测查了师生认知方式相互作用对双语儿童学业成绩的影响,研究结果表明：师生认知方式的相互关系对学生的学业成绩有显著的影响,这种影响与学科性质、学习任务有关;双语儿童的认知方式是影响其汉语文、数学成绩的重要因素;不周性别师生认知方式的相互匹配对其汉语文的学习有显著影响;师生认知方式的相互作用对双语儿童学习成绩的影响并非是线性的,师生间性别、认知方式相互作用都是影响双语儿童学业成绩的重要变量。     

以实质心理学为基础的评估：认知诊断

评价除了了解学习者的学习情况外,同时还应该提供学习者学习状况的诊断信息,以利于教学与学习。评价应该以认知心理学对学习过程的研究,作为编制测验的实质理论依据,进行认知诊断评估。本文针对认知诊断的心理学基础：知识的习得、知识诱发、知识表征、知识结构等进行梳理,以便测验开发者对认知诊断评估有更清晰的认识。     

Enhanced music sensitivity in 9-month-old bilingual infants

This study explores the influence of bilingualism on the cognitive processing of language and music. Specifically, we investigate how infants learning a non-tone language perceive linguistic and musical pitch and how bilingualism affects cross-domain pitch perception. Dutch monolingual and bilingual infants of 8–9 months participated in the study. All infants had Dutch as one of the first languages. The other first languages, varying among bilingual families, were not tone or pitch accent languages. In two experiments, infants were tested on the discrimination of a lexical (N = 42) or a violin (N = 48) pitch contrast via a visual habituation paradigm. The two contrasts shared identical pitch contours but differed in timbre. Non-tone language learning infants did not discriminate the lexical contrast regardless of their ambient language environment. When perceiving the violin contrast, bilingual but not monolingual infants demonstrated robust discrimination. We attribute bilingual infants’ heightened sensitivity in the musical domain to the enhanced acoustic sensitivity stemming from a bilingual environment. The distinct perceptual patterns between language and music and the influence of acoustic salience on perception suggest processing diversion and association in the first year of life. Results indicate that the perception of music may entail both shared neural network with language processing, and unique neural network that is distinct from other cognitive functions.     

Claiming Subjectivity: Re-Storying Clinical Psychology and Myself

This article explores becoming a clinical psychologist later in life. Drawing on the author’s experience as a developmental psychologist who becomes a clinical respecialization student, it traces shifts in narratives of identity, belongingness, perspectives on psychology, and ways of knowing that both influence and construct her perspective on age and midlife. The paradigm shifts of going from professor, to student and intern, and philosophical shifts, transitioning from a stance of objectivity, to one informed by deep subjectivity, are considered. The ways that age matters is pondered as an artifact of the larger social construction of aging. The article proposes that a rich later-in-life perspective often includes the capacity to utilize self-knowledge and affective interpretation that nurtures subjectivity. The capacity to summon subjectivity facilitates rich authentic empathic connection with patients in clinical practice. The author explores the process of learning and re-storying herself in a manner that draws on self-reflection, clinical subjectivities, the life-learned ability to be humble, and a theory-informed lens of clinical psychology that is truly different from developmental psychology. The promise for future contributions to both clinical work and the greater field by “new” clinicians at midlife is explored.     

A Comparative Study of Shifting Ability,Inhibitory Control and Working Memory in Monolingual and Bilingual Children

It is now well documented that the linguistic development of bilingual children is, in many respects, different from that of their monolingual peers. Yet, there is substantial evidence in cognitive psychology that the effect of bilingualism is not merely restricted to the linguistic competence of individuals. Recent literature on bilingualism suggests that certain aspects of children’s cognitive development can be positively affected by the bilingual experience. The aim of the present study was to investigate the potential effects of bilingual experience on young children’s executive processing. A total of 67 preschool children belonging to two groups including 36 Persian–Turkish bilingual children and 31 Persian monolingual children participated in the study. They were matched for their verbal proficiency and then were compared on three executive function tasks including shifting ability, inhibitory control and working memory. Results showed that bilingual children outperformed monolinguals on both shifting and inhibitory control tasks. However, both groups performed similarly on working memory tasks. The findings are interpreted in terms of the enhanced ability of bilingual children in various executive functions processing.     

The role of embodied intention in early lexical acquisition

We examine the influence of inferring interlocutors' referential intentions from their body movements at the early stage of lexical acquisition. By testing human participants and comparing their performances in different learning conditions, we find that those embodied intentions facilitate both word discovery and word-meaning association. In light of empirical findings, the main part of this article presents a computational model that can identify the sound patterns of individual words from continuous speech, using nonlinguistic contextual information, and employ body movements as deictic references to discover word-meaning associations. To our knowledge, this work is the first model of word learning that not only learns lexical items from raw multisensory signals to closely resemble infant language development from natural environments, but also explores the computational role of social cognitive skills in lexical acquisition.     

Enhancing the Learning and Retention of Biblical Languages for Adult Students

Abstract. Finding ways to reduce students’ anxiety and maximize the value of learning Greek and Hebrew is a continual challenge for biblical language teachers. Some language teachers use technology tools such as web sites or CDs with audio lessons to improve the experience. Though these tools are helpful, this paper explores the value gained from understanding first how students learn and then how technology tools best support that learning. Developments in cognitive psychology and neuroscience offer many insights concerning adult learning and retention. After a presentation of key insights, several ideas are suggested for enhancing the learning and retention experience of biblical language students.     

第二语言获得关键期研究进展

语言获得的关键期是发展心理学的一个重要且有争议的问题。近二十多年来．国外学者对第二语言获得年龄与第二语言的学习速度,第二语言的获得年龄与最后达到水平,第二语言的获得年龄与第二语言的大脑皮质表征和加工的关系等问题进行探讨,得到了复杂的结果。该领域的研究有待进一步控制与年龄相关的变量和认知变量,并将行为和脑功能的研究结合起来．更深入地探讨这一问题。     

Enculturation and narrative practices

Recent work on enculturation suggests that our cognitive capacities are significantly transformed in the course of the scaffolded acquisition of cognitive practices such as reading and writing. Phylogenetically, enculturation is the result of the co-evolution of human organisms and their socio-culturally structured cognitive niche. It is rendered possible by evolved cerebral and extra-cerebral bodily learning mechanisms that make human organisms apt to acquire culturally inherited cognitive practices. In addition, cultural learning allows for the intergenerational transmission of relevant knowledge and skills. Ontogenetically, enculturation is associated with neural plasticity and the development of new motor routines and action schemas. It relies on scaffolded learning that structures novice-teacher interactions. The acquisition of reading and writing are paradigm examples of enculturation. Based on an empirically informed analysis of the components of enculturation, I will apply the emerging account of enculturated cognition to narrative practices. To date, research on the impact of narratives on the constitution of the self and our understanding of folk psychology has not paid much attention to the question how narratives are influenced by cumulative cultural evolution and our capacity to acquire reading and writing during ontogeny. I will argue that textual narratives, above and beyond oral narratives, provide genuinely new ways of narration. Therefore, the enculturated interaction with textual narratives has the potential to contribute to a better understanding of ourselves and other cognitive agents.
