儿童认知发展水平诊断工具IPDT的动态化编制及其在低社会经济地位儿童中的应用

“皮亚杰认知发展量表” (IPDT)中的守恒与关系领域经动态化改编后已被证实适用于小学低年级儿童的潜能评估。在此基础上, 本研究旨在构建适用于小学高年级儿童的IPDT表征、分类、规律领域的动态测验; 并运用所构建的IPDT动态测验对低社会经济地位(SES)儿童进行认知潜能评估; 而后经过对低SES儿童的推理认知干预, 进一步考查认知干预在低SES不同潜能儿童的认知能力和数学成就中的促进作用。结果发现：(1)改编的IPDT表征、分类、规律领域的动态测验包含“前测—干预—迁移—后测”4个阶段, 所构建的逐级提示干预方案合理适切, 可以有效区分不同认知潜能水平的小学高年级儿童, 特别是弱势儿童; (2)推理认知干预对由IPDT动态测验细致区分出的不同潜能水平的低SES儿童作用不同, 尽管他们在认知能力与数学成就上均有进步, 但低SES高潜能儿童比低SES低潜能儿童从干预中获益更多。     

动态测验对“数学学习困难”儿童的进一步甄别

本研究意在考查动态测验对数学学习困难儿童作进一步程度区分的有效性。以传统且常用的数学学习困难鉴别方式和标准选取30名四年级数学学习困难儿童为实验组,30名同年级智力匹配儿童为对照组,以Swanson认知加工测验(S-CPT)的4个子测验为测量工具对被试进行动态测验。结果发现：(1)在传统数学学习困难鉴别方式的基础上,动态测验的“潜在认知能力”指标可以对儿童数学成绩增加19%的预测力;(2)以“潜在认知能力”指标为依据能够将数学学习困难儿童进一步区分为“发展落后”和“发展缺陷”两个水平;(3)“发展落后”儿童一年内数学成绩发生了增长性变化,与正常儿童水平相当,而“发展缺陷”儿童的数学成绩没有变化。研究证实关注潜能指标的动态测验范式在快速、准确甄别数学学习困难儿童上具有独特效用。     

冲动型和思索型认知方式在儿童逻辑推理中的中介作用

通过选择相同图形测验(MFFT),小学一年级的儿童(平均年龄=6岁7月)被定为或具有“冲动型”(n=31)或具有“思索型”(N=33)两类不同的认知方式,然后分别在预试、启发和再测三个阶段,做性质相同的推理测验。对儿童在推理测验时自我解释的趋向的分析表明,思索型儿童在三次测试中都能注重答案的确实性。冲动型儿童预试时急于作答,但启发阶段由于主试的提醒和解释,纠正了急于作答的倾向并能注意答案的确实性,然而再测时由于测验的气氛,他们又恢复了急于作答而不注重答案准确性的倾向。结果,认知方式在一定情况下影响了儿童的推理成绩:预试时由于题的难度大思索型和冲动型儿童的成绩都不好,启发阶段两组儿童的进步都很大,然而再测试时,冲动型儿童退步,而思索型儿童却保持了启发后的水平。本实验结果意味着,在做一定难度的推理题时,思索型的认知方式会有助于儿童的成绩,而冲动型认知方式会掩盖儿童的能力。如果对冲动型的儿童随时多提醒些,让其自主支配时间,鼓励他们注重于答案的准确性,他们就可能改变认知方式而提高判断能力。     

IRT框架下追踪数据的测量不变性分析——————以4至5岁儿童认知能力测验为例

本研究以4岁~5岁儿童认知能力测验为例,在IRT框架下探讨了如何进行追踪数据的测量不变性分析。分析模型采用项目间多维项目反应理论模型(between-item MIRT model)和项目内（within-item MIRT model）多维two-tier model,被试为来自全国的882名48个月的儿童,工具为自编4岁~5岁儿童认知能力测验。经测验水平 分析和项目水平分析,结果表明：(1)本文对追踪数据的测量不变性分析方法合理有效; (2)该测验在两个时间点上满足部分测量不变性要求,测验的潜在结构稳定; (3)“方位题”的区分度和难度参数都发生变化,另有4题难度参数出现浮动; (4)儿童在4岁~5岁期间认知能力总体呈快速发展趋势,能力增长显著。     

儿童认知发展动态测验

动态测验是一系列有着共同基本假设的多种能力测验的统称,是以维果茨基的最近发展区理论和实验为基础,针对传统静态测验低估弱势儿童能力、缺乏对教育实践的有效指导而提出的测量范式。它采用与智力测验相似的项目,以学习率、迁移能力和认知改变为指标,通过在测验中提示和干预的方法考查个体潜在的认知发展水平。该着重介绍了当代动态测验影响较大的几种方法或技术：Feuerstein的中介学习、Budofr的训练测验、Campione和Brown的逐步提示法、Guthke的学习测验、Carlson和Wiedl的极限探测法,并试图对动态测验进行整体评价。     

基于IRT模型的儿童图形推理能力动态评估研究

MRMLC模型是一种常见的动态评估项目反应理论模型。本研究结合小学儿童图形推理能力发展的特点,采用前测-干预-后测的动态评估模式,对来自江西省北部的四到六年级共177名儿童的图形推理能力进行了基于MRMLC模型的动态评估。研究结果表明通过动态评估我们不仅可以获知儿童图形推理能力的当前水平;而且,还可以进一步分析和比较儿童在各测量情景所测的潜在水平。     

3～6岁儿童“心理理论”的发展

“心理理论”是发展心理学的研究热点,在儿童获得心理理论的年龄和发展阶段问题上仍存在争议。该研究以3所城市幼儿园中的233名3-6岁儿童为被试,采用“意外转移”和“欺骗外表”两个错误信念测验任务考察儿童“心理理论”的获得年龄和发展阶段。研究得出如下结论:3岁之前儿童已理解外表与真实的区别,但还不能理解错误信念。 4岁儿童理解了欺骗外表任务中自己和他人的错误信念,5岁儿童理解了意外转移任务中的错误信念。4-5岁是儿童获得“心理理论”的关键年龄,但这会因测验任务的不同而有所差异。儿童的错误信念理解不存在显著的性别差异。

Cognitive and emotional aspects of self-regulation in preschoolers

The goal of the present study was to examine the contribution of executive function (EF) and social cognition to individual differences in emotion regulation (ER) in preschool children. Sixty 3-, 4-, and 5-year-old children were administered a battery of EF tasks, two theory of mind tasks, a measure of verbal ability, and an ER task. In addition, parents completed the Behavior Rating Inventory of Executive Functioning—Preschool Version (BRIEF-P). Performance on the theory of mind tasks as well as parental ratings of executive function was not related to performance on the ER task. However, a component of EF (i.e., inhibition) approached significance with children's displays of positive behaviors during the ER task. Verbal ability was related to the regulation of positive but not negative emotions. Parental ratings of shifting accounted for a significant amount of variance in parental ratings of ER, even after controlling for verbal ability. The findings are discussed in the context of different conceptualizations of the developmental relation between ER and EF.     

Implications of Timing of Maternal Depressive Symptoms for Early Cognitive and Language Development

: Statistically, women, particularly pregnant women and new mothers, are at heightened risk for depression. The present review describes the current state of the research linking maternal depressed mood and children's cognitive and language development. Exposure to maternal depressive symptoms, whether during the prenatal period, postpartum period, or chronically, has been found to increase children's risk for later cognitive and language difficulties. The present review considers both the timing of maternal depression and the chronicity of mothers' depression on children's risk for cognitive and language delays. Infancy is frequently identified as a sensitive period in which environmental stimulation has the potential to substantially influence children's cognitive and language development. However, children's exposure to chronic maternal depression seems to be associated with more problematic outcomes for children, perhaps because depression interferes with mothers' ability to respond sensitively and consistently over time. Consistent with this expectation, interventions targeting parenting practices of depressed mothers have been found to increase children's cognitive competence during early childhood. The current review provides a synthesis of the current state of the field regarding the association between maternal depression and children's cognitive and language development during early childhood.     

部件特征和正字法意识在儿童汉字书写发展中的作用

研究以北京地区262名汉语儿童为研究对象,探讨了部件复杂程度和部件数量对儿童延迟抄写成绩的影响,并通过一年的追踪,考察了儿童书写加工基本单位及其发展变化历程,并分析了儿童的正字法意识对其书写能力发展的预测作用。实验一发现汉语儿童的书写单位是一个从笔画到部件的多水平发展过程,在控制整字笔画的情况下,对于部件复杂的汉字,以笔画为单位进行编码,错误类型以笔画乱写和部件错误为主,而对于由简单部件组成的汉字,主要以部件为单位进行组块,儿童多犯部件替换的错误。实验二发现在部件复杂程度相同的情况下,汉字所包含的部件数量越多,儿童的书写正确率越低,多犯部件缺失和部件替换的错误。实验三发现儿童一年级的正字法意识能够显著预测当年及一年后的书写成绩,表明正字法意识对于儿童的书写发展具有重要作用。     

因果变化模式与因果联结强度在幼儿因果推理中的作用

对93名幼儿进行了五种因果变化模式的因果推理题目的测试。结果表明:(1)在不同的因果变化模式下,被试进行因果推理的成绩存在差异,且在对于这五类题目的掌握上具有一定的顺序。(2)被试在同样因果变化模式题目的表现之间具有较高的相似性,而在因果联结强度相同的题目之间则具有显著的差异。(3)被试对于各题目回答的正确率并不随原因与结果联结次数的增多而提高。(4)即使是在观察到的刺激完全一致的情况下,被试的回答仍会因因果变化模式的差异及主试对于题目解释的不同而存在差别。     

Phonological awareness, executive functioning, and theory of mind

Language plays a critical role in theory of mind (ToM) development, particularly the understanding of false beliefs (FB). Further, there is some evidence that the development of FB is important for metalinguistic development, such as the understanding of homonyms and synonyms. However, there is debate regarding the nature of this relationship. This study explored the role of ToM, including FB, understanding and executive function in another aspect of metalinguistic development involving phonological awareness, specifically rhyming. Of interest was the relative role of ToM and executive function, particularly inhibitory control, in children's ability to identify rhymes. Two studies of 4-year-olds demonstrated that ToM understanding was primarily associated with rhyming ability, whereas inhibitory control was not independently related. Results are discussed in terms of children's ability to flexibly shift between different perspectives, by bracketing one perspective and focusing on the other, in both metalinguistic and ToM tasks.     

7～11岁儿童失言理解及与母亲教养方式的关系

采用失言任务和改编后的教养方式问卷探讨7~11岁儿童心理理论的发展及其与母亲教养方式的相关。结果表明,在学龄期,儿童在不同层面上对失言的理解能力仍在提高,高年级时已超出单一维度。7岁儿童对包含意图的信念理解与母亲的"过度偏爱"显著负相关;8岁儿童对包含意图的信念理解与母亲的"惩罚和严厉"显著负相关。结果提示在某些年龄阶段,儿童心理理论的发展可能与母亲特定的教养方式有关。     

儿童阅读与心理理论间的关系

阅读与心理理论(theory of mind, ToM)在儿童发展过程中都发挥着重要的作用, 梳理文献发现两者可能存在双向促进作用。儿童通过与家长或老师的共享阅读, 启动联合注意, 使用心理状态术语进行对话, 进一步根据社会想象力, 模拟社会互动, 从而促进儿童心理理论发展。另一方面, 在阅读过程中, 心理理论能够助力儿童从宏观的阅读观的建立、元认知阅读策略的使用、故事情境模型的构建, 到微观具体的短语、句子、语篇和多文本的理解等能力的提高, 这些证据揭示了心理理论可以从多方面促进儿童阅读能力的发展。进一步的神经生理证据发现, 阅读和心理理论这两个过程的神经活动是有一定重叠的。由此推测, 两者可能具备潜在的双向促进关系。未来需要更深入和长期的纵向追踪研究为两者的关系提供丰富的实证证据。此外, 还应进行更多中国的低龄儿童的研究。随着科技的发展和线上课程的盛行, 也应更多关注多媒体内容阅读对儿童心理理论的影响。     

5~6岁儿童传递推理能力的发展特点

通过有效的实验设计,在控制儿童记忆容量影响的前提下,考察了5~6岁儿童在长度传递推理和重量传递推理能力上的发展水平。结果表明:(1)5~6岁是儿童传递推理能力迅速发展的时期。在大概6岁左右,大多数儿童已经能够进行真正意义上的传递推理。(2)此年龄儿童在长度传递推理和重量传递推理能力上不具有显著差异。(3)条件排列的一致与不一致对于被试的推理成绩并不具有显著影响。     

The relationship between the shape of the mental number line and familiarity with numbers in 5- to 9-year old children: evidence for a segmented linear model

This experiment aimed to expand previous findings on the development of mental number representation. We tested the hypothesis that children's familiarity with numbers is directly reflected by the shape of their mental number line. This mental number line was expected to be linear as long as numbers lay within the range of numbers children were familiar with. Five- to 9-year-olds (N=78) estimated the positions of numbers on an external number line and additionally completed a counting assessment mirroring their familiarity with numbers. A segmented regression model consisting of two linear segments described number line estimations significantly better than a logarithmic or a simple linear model. Moreover, the change point between the two linear segments, indicating a change of discriminability between numbers, was significantly correlated with children's familiar number range. Findings are discussed in terms of the accumulator model, assuming a linear mental representation with scalar variability.     

Theory of mind and epistemological development: the relation between children's second-order false-belief understanding and their ability to reason about evidence

The study investigates the hypothesis that children's ability to attribute second-order beliefs facilitates their understanding of evidence, as seen in the ability to distinguish between causes and reasons. Seventy-four children 5–7 yr old were given belief and evidence tests. The belief tests assessed their ability to represent and reason from second-order false-beliefs, and the evidence tests assessed their ability to distinguish between the cause of a situation and a person's reason for believing it. The relation between performance on the two tests was determined, taking into account general language and non-verbal reasoning abilities. Results show that performance on the belief test and on the evidence part of the evidence test improved significantly over the age range, and that a significant proportion of variance in the evidence test scores is accounted for by second-order false-belief understanding, over and above that accounted for by general language and non-verbal abilities. The argument is made that second-order false-belief understanding is fundamental to children's epistemological development, underlying not just their understanding of evidence, but also their understanding of inference and truth.
