6~10岁儿童对损人情境下行为者的道德情绪判断与归因

采用故事情境法探讨6~10岁儿童对损人情境下损人者和旁观者的道德情绪判断与归因的发展。结果发现：（1）在损人情境下,6岁儿童能理解损人行为是不对的,但直到8岁儿童才能理解旁观行为是不对的;（2）随着年龄增长,儿童判断损人者的愉悦程度逐渐降低,情绪归因从结果定向过渡到道德定向;儿童判断旁观者的愉悦程度逐渐降低,情绪归因从无法有效归因过渡到道德定向;（3）儿童对不同行为者的道德情绪判断同时受年龄和性别的影响,6岁男孩判断损人者愉悦程度显著高于女孩,6岁男孩判断旁观者愉悦程度显著低于女孩;8岁和10岁儿童对两类行为者的道德情绪判断未发现显著的性别差异。     

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。     

3～9岁儿童人格特质稳定性理解的发展特点

采用情境故事法对281名3～9岁儿童对不同类型的消极或积极特质稳定性的理解进行了个别测查,使用了“性质-类型-性质”的特质推理研究范式,任务涉及跨时间稳定性和跨情境一致性两个层面的考察。五因素重复测量方差分析结果表明,3～9岁儿童对于特质稳定性的理解表现出随年龄发展稳定观不断增强的趋势,4岁可能是儿童特质稳定性理解由不成熟向成熟方向发展的关键点;此外,研究验证了年龄与特质性质的交互作用,也发现了问题类型和特质类型对特质稳定性理解的调节作用。这些特点与年幼儿童获得的心理知识和对特质发展影响因素的觉知有关,也可能与整个文化系统的直接或间接作用有关。     

2~3岁儿童在分配情境下的公平敏感性

公平敏感性是指个体对感知到的公平和不公平的稳定而个性化的反应, 其表现为个体对公平的不同偏好。本研究旨在考察2~3岁儿童公平敏感性发展特点, 并进一步探究分配情境、分配数量和分配结果等因素对儿童公平敏感性的影响。实验1采用VOE范式, 在第三方任务情境下, 考察130名2~3岁儿童公平敏感性的发展特点, 结果发现在VOE范式下, 2~3岁儿童公平敏感性随着年龄增长而上升, 3岁~3岁3个月儿童的公平敏感性发展最明显。实验2, 选取60名处于公平敏感性发展最明显的3岁~3岁3个月的儿童比较其在不同分配情境、分配数量以及分配结果下的注视时间差异。结果表明, 在有接受者情境下儿童公平敏感性显著高于无接受者情境下的公平敏感性, 并且公平敏感性受分配数量的影响。     

2～4岁儿童对"大""小"空间形容词词义掌握的研究

本研究以2～4儿童为研究对象。在自然实验条件下,通过精心设计的四项实验,得出结论：2岁儿童还未了解大小词义;2．5岁儿童能判别当前两同类物体的大小;3岁儿童能对两同类物体的大小相对性比较;4岁儿童能掌握不同类物体间大小的搭配;4岁儿童9成能掌握人与物间相对大小的匹配,但仅一半儿童掌握三个同类物体同时比较时大小相对关系,即4岁儿童还未对“大”“小”词义完全掌握。实验表明儿童掌握“大”“小”空间形容词是由易到难,由浅到深,由绝对禁止到相对灵活,由以自我为中心到以外界为中心。     

5～8岁儿童失言探测与理解的发展特点

失言探测与理解是一种融入了人际互动,需要个体体会交往双方心理感受的高级心理理论任务.本研究采用图片-故事法探讨失言情境(他人对自我、自我对他人和他人对他人 )对5～8岁儿童失言探测与理解的影响.结果发现,7～8岁儿童基本拥有了失言探测与理解能力,6、7、8岁儿童在所有情境下失言探测和理解能力同步发展,而5岁儿童在他人对自我情境下失言探测与理解的成绩显著好于自我对他人情境下的成绩,提示失言探测与理解能力在不同阶段会表现出不同的发展特点.     

数量让位价值：5～10岁儿童公平分配发展的“此消彼长”

操纵资源价值与数量的比例关系，形成互不影响的数量平等与价值平等，考察5～10岁儿童在不同卷入情境中公平分配发展的特点。结果发现：（1）6岁以后儿童公平分配发展存在数量平等“消”和价值平等“长”的特点；（2）与第一方卷入情境相比，在第三方卷入情境中9～10岁儿童公平行为发展存在差异，而公平认知不受卷入情境影响；（3）儿童公平认知发展能正向指导公平行为表现，但会受卷入情境、年龄和性别影响。     

儿童对愿望-规则冲突情境下他人情绪的理解

用设置故事情境的方法研究了儿童对愿望-规则冲突情境下他人情绪的理解.结果表明,在愿望和规则冲突情境故事条件下,随着年龄的增长,儿童更多地作出对他人的愿望和情绪不匹配的情绪预测,7岁儿童已达到成人水平;7岁相对于4、5、6岁儿童更多地提供混合情绪预测.随着年龄的增长,儿童越来越能认识到规则、预期的结果对他人情绪的影响.规则的来源影响儿童对他人情绪的理解,相对于内部规则,4、5岁儿童更多地将消极情绪归于违背外部规则的人,7岁和成人更多地将消极情绪归于遵守外部规则的人.     

5-7岁儿童绘画中社会地位的“大/小”隐喻表征

“大/小”隐喻是空间隐喻的一种.本研究设置了两项绘画主题, “警察抓小偷”和“园长和老师”,考察了5-7岁儿童在两项绘画任务中对“社会地位”这一抽象概念的“大/小”隐喻表征.结果发现:(1)儿童将社会地位较高的人物画得较大,将社会地位较低的人物画得较小,表明5-7岁儿童的概念体系中已经建立了社会地位的“大/小”隐喻;(2)不同绘画主题下,儿童绘画中的“高社会地位”与“低社会地位”人物大小差异的年龄变化趋势不同, “警察抓小偷”主题绘画中,随着年龄的增长, “警察”和“小偷”二者的大小差异逐渐缩小,但“园长和老师”主题绘画中却未发现这种差异,这一结果表明儿童的社会地位概念隐喻系统还不稳定.     

竞争和合作对学龄前儿童分配模式的影响:心理理论和抑制控制的作用

研究考察在双方贡献不相等时,3~6岁儿童分配模式的发展趋势及其原因。98名儿童在竞争或合作情境下和玩偶进行钓鱼游戏,然后对6枚冰箱贴进行分配。结果发现5~6岁儿童比3~4岁儿童进行平均分配的比例更高,一级心理理论和抑制控制能力完全中介了年龄的效应。和竞争情境相比,合作情境促进儿童进行平均分配,同时情境调节了抑制控制对分配模式的影响。研究表明一级心理理论和抑制控制能力的发展能够解释学龄前儿童分配模式的变化。     

The growth of lexical constraints on spoken word recognition

In this study, we examined the influence of various sources of constraint on spoken word recognition in a mispronunciation-detection task. Five- and 8-year-olds and adults were presented with words (intact or with word-initial or noninitial errors) from three different age-of-acquisition categories. "Intact" and "mispronounced" responses were collected for isolated words with or without a picture referent (Experiment 1) and for words in constraining or unconstraining sentences (Experiment 2). Some evidence for differential attention to word-initial as opposed to noninitial acoustic-phonetic information (and thus the influence of sequential lexical constraints on recognition) was apparent in young children's and adults' response criteria and in older children's and adults' reaction times. A more marked finding, however, was the variation in subjects' performance, according to several measures, with age and lexical familiarity (defined according to adults' subjective age-of-acquisition estimates). Children's strategies for responding to familiar and unfamiliar words in different contexts are discussed.     

In search of perceptual influences of sentence context on word recognition

A major issue in the study of word perception concerns the nature (perceptual or nonperceptual) of sentence context effects. The authors compared effects of legal, word replacement, nonword replacement, and transposed contexts on target word performance using the Reicher-Wheeler task to suppress nonperceptual influences of contextual and lexical constraint. Experiment 1 showed superior target word performance for legal (e.g., "it began to flap/flop") over all other contexts and for transposed over word replacement and nonword replacement contexts. Experiment 2 replicated these findings with higher constraint contexts (e.g., "the cellar is dark/dank") and Experiment 3 showed that strong constraint contexts improved performance for congruent (e.g., "born to be wild") but not incongruent (e.g., mild) target words. These findings support the view that the very perception of words can be enhanced when words are presented in legal sentence contexts.     

Demonstrations of a generation effect in context memory

Generation often leads to increased memorability within a laboratory context (see, e.g., Slamecka & Graf, 1978). Of interest in the present study is whether the benefits of generation extend beyond item memory to context memory. To investigate this question, in three experiments, we asked subjects to remember in which of two contexts they had read or generated words. In Experiment 1, the contexts were two different rooms; in Experiment 2A, the contexts were two different computer screens; in Experiment 2B, the contexts were different perceptual characteristics of the to-be-remembered words. In all experiments, subjects were better at remembering the context of generated words than of read words.     

The metric matters: determining the extent of children's knowledge of morphological spelling regularities

All developmental research needs to carefully consider how children's knowledge is measured. The study of children's knowledge of spelling conventions, or the ways in which the English orthography encodes the roots and affixes and the sounds in words, is no exception. This experiment examined the extent of 7- to 9-year-old children's knowledge of the role of root morphemes in spelling words across different contexts and with different units of assessment. Different writing contexts did not appear to affect children's performance; children were better able to spell the first components of two- than of one-morpheme words (e.g. only free in freely and freeze), both when writing whole words and their first sections (e.g. completing__ or __ly for freely). A second analysis revealed that the unit of coding can influence conclusions. Children demonstrated similar abilities across ages 7 to 9 when only the first segments of words were coded; in contrast, there was evidence of age-related differences when whole word spelling accuracy was assessed. In combination, these results suggest that children's knowledge of the principle of root consistency is remarkably robust to changes in writing context, but that coding is key when drawing conclusions. These findings remind us that the metric matters in studies of spelling, as in other domains, and they offer a manner to reconcile previously conflicting data on spelling development.     

Enduring influence of the purpose of experiences: Encoding-retrieval interactions in word and pseudoword perception

Letters in words are identified more easily than are letters in nonwords or letters alone. These effects may depend on separate representations of general lexical attributes and of specific contexts, or on memory for particular experiences. We required subjects to associate meanings with some pseudowords and to perform a physical analysis on others. After 24 h, subjects identified pseudowords associated with meanings more accurately than novel or physically analyzed pseudowords. However, perceptual accuracy was independent of recall of meanings, suggesting that meaning was not available as a context-free resource. Instead, perceptual accuracy was correlated with the interdependence of stimulus components in perception, suggesting that encountering pseudowords for different purposes had caused different perceptual organizations, which exercised lasting influence. We concluded that the perceptual advantage of words may be incidental to the purposes for which words are ordinarily processed, and may depend on preservation of particular perceptual experiences.     

A test of the Sophisticated Guessing Theory of word perception

Under difficult viewing conditions, a letter in a familiar word can be perceived more accurately than the same letter alone or in a string of unrelated letters. Sophisticated Guessing Theory asserts that perception is more accurate when a letter appears in a word because its identity is constrained by the identity of neighboring context letters. Experiment 1 tested the following prediction: A letter in a word should be perceived more accurately in strongly constraining word contexts than in weakly constraining word contexts. No such trend was found using a number of different measures of contextual constraint and perceptual accuracy. Experiment 2 verified that, with the same conditions used in Experiment 1 to test Sophisticated Guessing Theory, a strong perceptual advantage could be obtained for letters in words vs. letters alone or in unrelated-letter strings. Several alternative theories of word perception are discussed. The most attractive asserts that for words an additional higher-level perceptual code is formed that is more resistant to degradation than the code formed for letters.     

Dynamics of Word Comprehension in Infancy: Developments in Timing, Accuracy, and Resistance to Acoustic Degradation

Online comprehension of naturally spoken and perceptually degraded words was assessed in 95 children ages 12 to 31 months. The time course of word recognition was measured by monitoring eye movements as children looked at pictures while listening to familiar target words presented in unaltered, time-compressed, and low-pass-filtered forms. Success in word recognition varied with age and level of vocabulary development, and with the perceptual integrity of the word. Recognition was best overall for unaltered words, lower for time-compressed words, and significantly lower in low-pass-filtered words. Reaction times were fastest in compressed, followed by unaltered and filtered words. Results showed that children were able to recognize familiar words in challenging conditions and that productive vocabulary size was more sensitive than chronological age as a predictor of children's accuracy and speed in word recognition.     

They call it like they see it: spontaneous naming and attention to shape

Two experiments explore children's spontaneous labeling of novel objects as a method to study early lexical access. The experiments also provide new evidence on children's attention to object shape when labeling objects. In Experiment 1, the spontaneous productions of 21 23- to 28-month-olds (mean 26;28) shown a set of novel, unnamed objects were analyzed both in terms of the specific words said and, via adult judgments, their likely perceptual basis. We found that children's spontaneous names were cued by the perceptual feature of shape. Experiment 2 examines the relation between spontaneous productions, name generalizations in a structured task, and vocabulary development in a group of children between 17 and 24 months of age (mean 21;6). Results indicate that object shape plays an important role in both spontaneous productions and novel noun generalization, but contrary to current hypotheses, children may name objects by shape from the earliest points of productive vocabulary development and this tendency may not be lexically specific.     

3~5岁儿童的交换行为研究

设计了一个贴近现实的玩具交换任务,考察3~5岁儿童在玩具交换情境中的行为特点及其利用社会知觉信息指导交换选择的能力,被试为91名3~5岁儿童,男女各半。结果发现,随着年龄增长,儿童在交换任务中得分有显著增长,通过率由43.3%（3岁组）上升到85.5%（5岁组）。儿童对成功的交换行为的解释逐渐偏向于参与交换的人物而非交换的物品。这表明儿童利用社会知觉信息进行行为决策的能力在3~5岁间有明显的发展。     

Electrophysiological indices of brain activity to "the" in discourse

In a first experiment, we recorded event-related-potentials (ERPs) to "the" followed by meaningful words (Story) versus "the" followed by nonsense syllables (Nonse). Left and right lateral anterior positivities (LAPs) were seen from the onset of "the" up to 200 ms in both conditions. Later than 200 ms following the onset of "the", the left and right LAPs continued for "the" in the Story, but were replaced by a negativity in the Nonse Condition. In a second experiment, ERPs were recorded to "the" in the Story and Nonse contexts mixed together under two different task instructions (attend to the auditory stimuli versus ignore the auditory stimuli). The same pattern of findings as Experiment 1 were observed for the Story and Nonse contexts when the participants attended to the auditory stimuli. Ignoring the auditory stimuli led to an attenuation of the right LAP, supporting the hypothesis that it is an index of discourse processing.
