早期高级认知发展与前额叶功能发育的fNIRS研究

儿童早期阶段是各项认知能力和脑发育的关键阶段。近红外光谱成像技术(fNIRS)凭借其非侵害性、便捷操作以及对头动容忍度高等特点,在早期阶段儿童认知发展与脑发育的研究中得到越来越多的应用。从早期高级认知发展与前额叶功能的单侧优势变化、对应前额叶脑区逐渐专门化、发展关键期与前额叶功能的可塑性,以及前额叶功能异常与早期发展障碍的关系等四个方面对基于fNIRS技术开展的早期认知发展与脑发育的研究进展进行了梳理和分析。指出未来研究应探究儿童早期认知能力发展和脑发育的轨迹及关键期,探讨有发展性障碍家族风险儿童的早期大脑发育特点,为早期教育和发展障碍的早期预警提供依据。     

多面体的一面:第二语言学习的社会化过程

第二语言学习过程是社会互动情景中的言语活动,"热"的社会化过程是第二语言学习过程的有机组成部分;形成第二语言情景下的文化心理参照系认知能力和文化适应能力是第二语言的言语能力重要内容;第二语言学习过程中的言语变异现象部分源于学习者的社会心理结构特征。     

儿童执行功能对数学能力的预测模型

使用数点数广度任务(C-span)、Stroop任务、威斯康星卡片分类任务(WCST)测查儿童的执行功能,用《小学儿童数学能力测查量表》(一年级)、《韦克斯勒儿童智力测量》分别测查儿童的数学能力和智力,对64名小学一年级儿童的执行功能(抑制、转换、刷新)和数学能力的关系进行了研究,相关分析和回归分析发现,数学能力与执行功能任务测量都有显著相关,抑制、转换和刷新都分别对数学能力存在显著回归效应;在此基础上,建立了执行功能及其对儿童数学能力的预测模型。结果表明,抑制控制、转换和刷新都能对数学能力产生直接影响,但抑制控制还通过转换和刷新对数学能力产生间接影响。说明儿童数学能力的认知差异,主要在于抑制控制能力的差异,而抑制控制的差异又导致转换和刷新能力表现的差异。     

中学生感恩与主观幸福感的关系:抗挫折能力与社会支持的中介作用

采用感恩问卷、正性情感负性情感量表、生活满意度问卷、抗挫折能力问卷和社会支持评定量表对865名中学生进行调查, 以考察中学生感恩和主观幸福感的关系, 以及社会支持与抗挫折能力在两者之间的中介作用。结果:(1)中学生正性情绪显著高于负性情绪;(2)中学生感恩与主观幸福感、社会支持、抗挫折能力相关显著;(3)结构方程分析结果显示, 中学生感恩直接负向预测负性情绪;社会支持和抗挫折能力在感恩与生活满意度、正性情绪间起到完全中介作用, 抗挫折能力在感恩和负性情绪间起部分中介作用。 结论:感恩能通过作用于社会支持和抗挫折能力来影响主观幸福感。     

读后续写在医学生叙事能力培养中的应用

叙事性阅读和写作能力是叙事能力的重要组成部分,在叙事能力培养过程中应得到充分的重视。读后续写作为一种把语言的输入和输出紧密结合的语言教学方法,对于培养学生的阅读和写作能力有重要作用。所以,在叙事能力培养的过程中,尤其是初级阶段,读后续写可用于训练和培养学生的叙事性读写能力。通过教学实践发现,读后续写把叙事性阅读和写作联系起来,能提高学生的叙事性阅读和写作能力,并帮助学生进行换位思考,提高其共情能力,最终提升学生的整体叙事能力。     

中学高年级学生作文能力结构特征的研究

对４９０名高三学生的１８个作文变量的测验资料,运用高阶因素分析法概括出中学高年级学生作文能力结构的三个群因素。第一个是作文能力的因素,它是作文认知活动的各种能力相互作用的一种协调发展程度。第二个是由词汇量、造句等能力组合成的词语能力,它是作文能力结构中的一个活跃因素。第三个是词汇量因素,它独立存在于一阶、二阶因素中,表明它是不同阶段认知活动的一个不可缺的因素。     

工作记忆训练的研究述评*

以往研究表明,工作记忆是一个资源有限的系统,但近年来大量研究发现工作记忆成绩可以通过训练提高。工作记忆训练是指针对低容量的个体进行针对存储系统或者中央执行系统各成分的训练,以提升个体工作记忆绩效及影响任务相关脑区的活动。来自认知神经科学的证据在评估工作记忆训练的效果上起到了重要作用。虽然目前该领域的研究已经取得一定的成绩,但是利用工作记忆训练来改善个体的工作记忆在具体的方法、训练成效等问题上还存在一定的争议。     

Thinking Childbirth from an Emancipatory Perspective? Phenomenology and Psychoanalysis1

Feminist thought, despite the importance of its work, has not resolved the phenomenon of women's subordination in the care and education of children, and in society as a whole. Meanwhile, we are witnessing a gradual but continuous process of disconnection between women's bodies and subjectivity, and the conception, pregnancy and birth of children, due to developments in reproductive techniques. Considering this paradoxical tension, the author proposes to return to the very place where this subordination and anticipated rupture occur, to consider whether mothers could find there both the means to reclaim their childbirth experiences and potential levers for emancipation and rebirth, on both a personal and societal level. To this end, she describes, from the point of view of a singular woman, and from an emancipatory perspective, the phenomenological and psychoanalytical itinerary of childbirth by which this woman, in becoming a mother, is born to herself by giving birth to her child. By co-constituting the universal meaning of childbirth and becoming a philosophical mother, this singular woman operates a real paradigm shift in our representations of the mother and the metaphysical structure of the sexes.     

Athletes’ ease of imaging predicts their imagery and observational learning use

Objectives

Following the development of the Sport Imagery Ability Questionnaire (SIAQ; Williams & Cumming, 2011), the aim of the present two studies was to more comprehensively examine the relationship between sport-related imagery ability and the functions of imagery and observational learning (OL) athletes report. A second aim was to establish the SIAQ’s predictive validity.

Design

Two samples of cross-sectional questionnaire data are presented in two studies.

Method

For both studies, athletes were recruited from a variety of team and individual sports, ranging in competitive level and years of experience. In Study 1, 117 participants (41 male and 76 female) with a mean age of 24.38 (SD = 9.46) completed the SIAQ and the Sport Imagery Questionnaire (SIQ; Hall, Mack, Paivio, & Hausenblas, 1998). In Study 2, 221 participants (83 male and 138 female) with a mean age of 22.34 (SD = 7.66) completed the SIAQ and the Functions of Observational Learning Questionnaire (FOLQ; Cumming, Clark, Ste-Marie, McCullagh, & Hall, 2005).

Results

Athletes’ imagery ability significantly predicted their imagery and OL use. Moreover, with the exception of performance OL, predictions were stronger when the type of imagery ability closely matched the function of imagery or OL being predicted.

Conclusions

As well as demonstrating the predictive validity of the SIAQ, results from both studies support the need to use imagery ability measures that most closely match the type of imagery or OL being used.     

Grey parrot numerical competence: a review

The extent to which humans and nonhumans share numerical competency is a matter of debate. Some researchers argue that nonhumans, lacking human language, possess only a simple understanding of small quantities, generally less than four. Animals that have, however, received some training in human communication systems might demonstrate abilities intermediate between those of untrained nonhumans and humans. Here I review data for a Grey parrot (Psittacus erithacus) that has been shown to quantify sets of up to and including six items (including heterogeneous subsets) using vocal English labels, to comprehend these labels fully, and to have a zero-like concept. Recent research demonstrates that he can also sum small quantities. His success shows that he understands number symbols as abstract representations of real-world collections, and that his sense of number compares favorably to that of chimpanzees and young human children.
