儿童在不同卷入情境下基于资源价值的分配行为特点：内群体偏爱的作用

为探究不同卷入情境下儿童基于资源价值的分配行为特点以及内群体偏爱在其中的作用, 呈现给儿童两种实验情境：实验1, 134名5~8岁儿童在第一方情境下与来自内、外群体的一名儿童分配不同价值的物品, 结果发现7~8岁儿童公平分配比例与5~6岁儿童无显著差异; 实验2, 130名5~8岁儿童在第三方情境下给来自特定群体的两名儿童分配资源, 结果发现7~8岁儿童公平分配比例显著高于5~6岁儿童。两个实验均发现儿童的分配行为表现出内群体偏爱, 5~6岁儿童比7~8岁儿童更明显。并且, 5~6岁女生比男生有更明显的内群体偏爱, 但在7~8岁组无性别差异。此外, 只有7~8岁儿童的公平分配行为表现出卷入情境上的差异, 他们在第三方情境比第一方情境下更能做出公平分配, 但5~6岁儿童的公平分配行为并无情境差异。综上可见, 比起年幼儿童, 年长儿童基于资源价值的公平行为发展得更好, 并且在两种卷入情境下受内群体偏爱的影响均更小。     

4～5岁儿童单双维类比推理能力的发展水平和特点

研究了儿童单双维类比推理能力的发展水平和特点。被试为 4岁到 5岁儿童 4 2名 ,男 19名 ,女 2 3名。三种实验条件分别为控制组、单维组、双维组 ,采用体现因果关系的图片类比推理材料。结果表明 :在具备相应知识经验的前提下 ,4岁组到 5 5岁组儿童的单维类比推理能力已接近形成 ,没有显著的年龄差异 ;4岁组到 5 5岁组儿童的双维类比推理能力均还处于较低的发展水平 ,但年龄差异显著 ,其中 5 5岁组儿童明显优于 5岁组 ,5岁组和 4 5岁组之间没有显著差异 ,4 5岁组显著优于 4岁组 ,在一定程度上反映出 4 5～ 5 5岁为儿童发展双维类比推理的“快速增长期”。实验中没有发现“练习效应”。     

不同分配情境下儿童公平行为的发展

为探究儿童在不同利益对比情境以及与己利益无关情境中的公平行为,研究呈现了自我任务的劣势博弈、优势博弈、冲突博弈以及第三方任务博弈四种分配情境。自我任务中儿童需要为自己与另一名匿名儿童迫选方案,第三方任务中则需为两名匿名儿童迫选方案。结果发现:(1)劣势博弈中所有年龄组均倾向于选择公平方案,而非劣势方案;(2)优势博弈中,8岁、10岁组选择公平方案的人显著多于优势方案,而4岁、6岁组均无显著差异;(3)冲突博弈中,4岁、6岁组选择优势方案的人显著多于劣势方案,而8岁、10岁组均无显著差异;(4)第三方博弈中, 8岁、10岁组选择公平方案的人显著多于不公平方案,而4岁、6岁组均无显著差异。这表明,4岁~6岁儿童尚未真正获得公平观念,且以获得个人利益为主;而8岁是真正获得公平观念的转折年龄,8~10岁儿童对人对己均坚持公平原则,且表现出利他倾向。

汉语学龄前儿童正字法意识的发展

本研究选择北京地区幼儿园3岁、4岁、5岁儿童各31、48、33名, 采用单部件意识测验和部件位置及功能意识测验系统探查了学龄前儿童的正字法意识各个层面的发展状况。单部件意识测验包括部件替换、部件缺失和部件旋转三个部分; 部件位置及功能意识测验分为假字和非字两个部分, 而非字又包括两形非字和形声非字。结果发现单部件意识测验中, 5岁组儿童在部件替换水平上的得分显著高于3岁组儿童, 而3岁组与4岁组、4岁组与5岁组儿童之间无显著差异; 部件缺失和部件旋转水平上, 三个年龄段的儿童的得分表现出明显的增长趋势。部件位置及功能意识测验中, 假字得分在三个年龄段之间无显著差异; 非字得分随年龄增长显著提高。这些结果表明, 单部件意识在学前期处于不断发展的阶段, 其中对部件替换的非字的拒绝能力发展较早, 部件缺失和部件旋转非字的拒绝能力发展较晚; 部件位置及功能意识在学前期已经开始发展, 3岁儿童已经具有假字符合正字法规则的认识, 但对非字违反部件位置合法性和功能完整性的认识直到4岁左右才开始萌芽, 5岁还未成熟。     

方言经验对早期沪语儿童汉语语音意识的影响

已有研究对汉语儿童的英语语音意识进行研究,且取得了很多有价值的研究成果,但对方言儿童的汉语语音意识的研究很少。汉语是一种具有众多方言的独特语言,许多方言和标准语的语言体系有着显著差异。具有方言和普通话早期经验的双语儿童在汉语语音意识上是否存在优势,有两种不同的看法：一是从心理语言学层面上,母语学习中获得的语言能力或普遍语法能促进第二语言的学习;二是从语言学层面上来讲,母语对第二语言的学习存在干扰作用。那么双语儿童在汉语语音意识上比单一普通话儿童是否存在优势呢？本研究将进行调查。实验选取72名4岁、5岁和6岁学前儿童为被试,每个年龄组各24人,其中沪语儿童和单一普通话儿童各12名。采用听觉呈现方法对所选被试进行汉语语音意识水平的测试,包括声调意识、声母意识和韵母意识三部分,并收集儿童的口语资料。结果表明: 虽然沪语儿童声母意识和韵母意识主效应不显著,但沪语儿童语音意识总成绩和声调意识成绩均比单一普通话儿童高;沪语儿童汉语语音意识优势不受年龄的影响。本研究启示是,上海地区学前儿童学习标准语（普通话）之外应鼓励使用沪语。

4~6岁汉语儿童正字法意识的萌芽与发展

研究旨在考察汉语学龄前儿童正字法意识的发展情况。在某中等城市一所幼儿园随机选择4岁、5岁、6岁三个年龄段的儿童各31、37、34名。实验一使用汉字、韩文和日文（平假名）作为实验材料探查学龄前儿童的汉字特异性意识;实验二使用上下结构、左右结构的真字、假字和非字考察学龄前儿童的部件位置意识。实验结果显示：（1）三组儿童都能区分日文和汉字,5岁左右儿童这种能力达到成熟。4岁儿童不能区分汉字和韩文,直到6岁,辨别汉字和韩文的能力也没有发展成熟。（2）三组儿童都能意识到假字符合正字法规则,但拒绝非字的能力在学前期尚未发展成熟,儿童在学前期不具备部件位置意识;6岁儿童更容易拒绝上下部件位置颠倒的非字。

Morphological Structure Processing During Word Recognition and Its Relationship to Character Reading Among Third-Grade Chinese Children

In the present study, we explored the characteristics of morphological structure processing during word recognition among third grade Chinese children and its possible relationship with Chinese character reading. By using the modified priming lexical decision paradigm, a significant morphological structure priming effect was found in the subject analysis when reaction time difference was considered as dependent variable. In the regression analyses, the children’s implicit morphological structure processing demonstrated a significant effect on Chinese character reading, even though its effect became non-significant when morphological awareness was entered. We achieved this result after controlling for the children’s age, non-verbal intelligence, and phonological awareness. These findings indicate that third grade Chinese children are sensitive to morphological structure information in the processing of compound words. Moreover, such sensitivity is, to some extent, a good predictor of Chinese children’s word reading performance.     

MORPHOLOGY MATTERS IN LEARNING TO READ: A COMMENTARY

This paper provides a review of current research on the relevance of morphological awareness to reading and reading instruction. On the assumption that many educators are relatively unfamiliar with morphology, children’s development of awareness of the morphemic structure of words is discussed, as is the need for children to learn strategies that will help them read, spell, and understand morphologically complex words. Educational practices and implications, based on theory and research findings, are presented. Results suggest that educators and educational researchers need to incorporate more word study into reading and spelling programs, focusing attention to both form and meaning. In addition, the value of instructional goals and programs in morphological awareness for children in the early elementary years needs to be explored.     

Are morphological structures computed during word recognition?

In the recent literature in generative morphology, it has been assumed that multimorphemic words must be characterized as having a hierarchical internal structure which is expressible in the form of morphological trees. This paper reports on an experiment which addresses the following question: Are these structures relevant to complex word recognition? In a naming latency experiment, subjects were presented with prefixed and suffixed nonsense roots. The use of stimuli such as these allowed for the control of real word effects such as frequency and semantic plausibility and made it possible to systematically vary the configuration of the morphological trees. Significant response time differences were found between the morphologically illegal forms and legal configurations. This was taken as evidence that subjects do compute morphological representations. Because no differences were found between legal left-branching structures and legal right-branching structures, it was concluded that morphological computation is not sensitive to the serial ordering of morphemes within a complex word.     

This turnip's not for turning: Children's morphological awareness and their use of root morphemes in spelling

We report on a study designed to examine children's understanding of (1) the connection between root morphemes and the spelling of inflected words and (2) the role of morphological awareness in this understanding. Seven‐ to 9‐year‐old children were given clues (e.g. turn) to the spelling of inflected and control words (e.g. turning and turnip). While the use of the clue was not specific to inflected words, spelling was better of the first segments (e.g. turn) of the inflected than of the control words. This difference suggests that children appreciate the role of root morphemes in spelling of inflected words. Further, it seems that morphological awareness is employed in the spelling of a wide range of words. These results are placed in context of current theories of spelling development.     

Initial morphological learning in preverbal infants

How do children learn the internal structure of inflected words? We hypothesized that bound functional morphemes begin to be encoded at the preverbal stage, driven by their frequent occurrence with highly variable roots, and that infants in turn use these morphemes to interpret other words with the same inflections. Using a preferential looking procedure, we showed that French-learning 11-month-olds encoded the frequent French functor /e/, and perceived bare roots and their inflected variants as related forms. In another experiment an added training phase presented an artificial suffix co-occurring with many pseudo-roots. Infants learned the new suffix and used it to interpret novel affixed words that never occurred during the training. These findings demonstrate that initial learning of sub-lexical functors and morphological alternations is frequency-based, without relying on word meaning.     

第二语言学习者形态复杂词的加工机制

大多数语言中, 形态复杂词所占的比例很高。形态复杂词形-义映射的规律性使得读者不仅能直接从心理词典中提取整词语义, 还可以利用形态规则来建构词语的语义。研究发现, 母语者可以利用形态规则来加工复杂词, 但第二语言(二语)学习者的研究结果存在较大的分歧, 且表现出和母语者不一样的结果模式。基于补充学习系统理论和情景性二语者假设, 我们尝试提出了二语形态复杂词加工机制的观点, 并据此解释研究分歧出现的原因。未来的研究需要探究词汇形态家族大小等因素对二语形态复杂词加工的影响, 以及揭示二语形态复杂词加工的神经机制。     

颜色词素在词义不透明双字词中的语义激活

多词素词的心理表征和和词义激活已成为心理语言学领域的研究热点。目前主要有三种理论:词素分解储存模型、整词储存模型和混合表征模型。针对词义不透明词中词素与整词的关系,利用语义启动和色词干扰的实验范式,对颜色词素在词义不透明双字词中的语义激活进行了研究。结果表明,词义不透明双字词的词素与整词之间存在着心理资源竞争,表现出相互抑制的关系,它们的力量对比随时间变化而改变,出现此消彼长的趋势。研究还表明,多词素词中的词素加工,不仅受词素结构影响,也受词素本身性质影响。由于颜色词素的加工既涉及语义系统,也涉及知觉系统,所以虽然在多词素词中处于附加词素的地位,也具有加工上的优势。     

小学低年级汉语儿童语素意识、汉字识别和词汇知识的发展关系——交叉滞后研究

以146名小学一年级儿童为研究对象, 进行了历时2年的3次追踪测试, 考察小学生从一到三年级的语素意识、汉字识别和词汇知识之间发展关系的变化。在控制了语音意识、快速命名、正字法意识、一般认知能力和自回归效应后, 结果发现：(1)一年级时的汉字识别显著预测二年级的同音语素意识和同形语素意识; (2)一年级时的词汇知识显著预测二年级的复合语素意识和汉字识别; (3)二年级时的汉字识别和词汇知识对三年级的同音语素意识、同形语素意识和复合语素意识均有显著预测作用; (4)二年级时的同形语素意识对三年级的词汇知识具有显著预测作用。结果表明, 小学一至三年级的汉字识别和词汇知识对语素意识具有预测作用; 三种语素意识对汉字识别和词汇知识的预测作用中, 只有同形语素意识能够显著预测词汇知识; 三种语素意识、汉字识别和词汇知识的发展关系存在变化且具有阶段性特点。     

Morphological knowledge as revealed in children's spelling accuracy and reports of spelling strategies

The goal of the current research was to assess whether children can make strategic use of morphological relations among words to spell. French-speaking children in Grade 4 spelled three word types: (a) phonological words that had regular phoneme-grapheme correspondences, (b) morphological words that had silent consonant endings for which a derivative revealed the silent ending, and (c) lexical words that had silent consonant endings for which no familiar derivative revealed the ending. Children were also asked to provide immediate retrospective reports of the strategies used to spell each word. Two experiments (Ns = 46 and 39) were conducted. As expected, children in Grade 4 spelled phonological words more accurately than they did words with silent consonant endings. In addition, children spelled morphological words more accurately than they did lexical words. Reports of using retrieval were associated with accurate performance across word types. Importantly, reports of using morphological strategies to spell morphological words were associated with a similar level of accuracy, as were reports of using retrieval. Even though children reported using a phonological strategy frequently across all word types, this strategy was associated with accurate performance only for spelling phonological words. Experiment 2 replicated the results of Experiment 1 with another set of stimuli and also showed that children's morphological awareness predicted their spelling accuracy for morphological words as well as the reported frequency of morphological strategy use. In sum, the findings revealed that most children showed evidence of adaptive strategy use.
