Many children experience great difficulty in learning their first color word. In contrast, once children have learned 1 color word, they learn additional color words more easily. This striking fact raises the question of whether children who do not know color words have conceptual color categories capable of supporting inferences about word meaning. In 3 experiments 2-year-olds were provided with tasks that required them to base inferences on color or to map things onto color. Half the children comprehended at least 1 color word, and the remaining children comprehended none. In all experiments, the children in both groups succeeded on the color tasks. It was argued that children who do not know color words have the conceptual foundation necessary to base inferences on color but have specific constraints against basing inferences about word meaning on color.  相似文献

Word-learning skills of 19 deaf/hard-of-hearing preschoolers were assessed by observing their ability to learn new words in two contexts. The first context required the use of a novel mapping strategy (i.e., making the inference that a novel word refers to a novel object) to learn the new words. The second context assessed the ability to learn new words after minimal exposure when reference was explicitly established. The children displayed three levels of word-learning skills. Eleven children learned words in both contexts. Five were able to learn new words rapidly only when reference was explicitly established. Two children did not learn new words rapidly in either context. The latter seven children were followed longitudinally. All children eventually acquired the ability to learn new words in both contexts. The deaf children's word-learning abilities were related to the size of their vocabularies. The present study suggests that word-learning strategies are acquired even when children are severely delayed in their language development and they learn language in an atypical environment.  相似文献

Children's attention to knowledge-acquisition events was examined in 4 experiments in which children were taught novel facts and subsequently asked how long they had known the new information. In Experiment 1, 4- and 5-year-olds tended to claim they had known novel animal facts for a long time and also reported that other children would know the novel facts. This finding was replicated in Experiment 2, using facts associated with chemistry demonstrations. In Experiments 3 and 4, children were taught new color words. 5-year-olds, but not 4-year-olds, distinguished between novel and familiar color words, reporting they had not known the novel words before the test session, but they had always known the familiar words. 4-year-olds in Experiment 4 were better able to distinguish novel and familiar color words when the teaching of the novel words was an explicit and salient part of the procedure.  相似文献

Word learning in children: an examination of fast mapping   总被引：1，自引：0，他引：1  
Children may be able to gain at least partial information about the meaning of a word from how it is used in a sentence, what words it is contrasted with, as well as other factors. This strategy, known as fast mapping, may allow the child to quickly hypothesize about the meaning of a word. It is not yet known whether this strategy is available to children in semantic domains other than color. In the first study, 2-, 3-, and 4-year-olds were introduced to a novel color, shape, or texture word by contrasting the new term with a well-known word from that domain. They were then tested for their ability to produce and comprehend the new term and for whether they knew what semantic domain the word referred to. The results show that even 2-year-old children can quickly narrow down the meaning of a word in each of the semantic domains examined, although children learned more about shape terms than color or texture words. A second study explored the effects of several variables on children's ability to infer the meaning of a new term. One finding of this study was that if the context is compelling, children can figure out the meaning of a new word even without hearing an explicit linguistic contrast.  相似文献

Many teachers make the assumption that CAL systems which use a touch screen are more effective for children with severe learning difficulties than those which use a concept keyboard. These two experiments look at which is more effective in helping these children to maintain a previously acquired sight vocabulary, and to learn new sight words. It was predicted that the touch screen would prove more effective because it places fewer information processing demands on pupils. Surprisingly, no difference was found between the two systems.  相似文献

Gestures are a natural form of communication between preverbal children and parents which support children's social and language development; however, low-income parents gesture less frequently, disadvantaging their children. In addition to pointing and waving, children are capable of learning many symbolic gestures, known as “infant signs,” if modeled by adults. The practice of signing with infants is increasingly popular in middle-income populations around the world, but has not been examined as an intervention to promote positive qualities of the parent–child relationship. This study tested whether an infant sign intervention (ISI) encouraging low-income parents to use symbolic gestures could enhance the parent–child relationship. A final sample of twenty-nine toddlers and their families were followed for 7 months after assignment to the ISI or a control group. Children and mothers in ISI group families used more symbolic gestures than those in control families. Mothers’ in the ISI group were more attuned to changes in children's affect and more responsive to children's distress cues. Mothers in the intervention group also viewed their children more positively, reducing parenting-related stress. This study provides evidence that a simple infant sign intervention is an effective tool to promote bidirectional communication and positive interactions for preverbal children and their parents.  相似文献

Kindergarteners (M age = 6;2) were exposed to novel spoken nonwords and their written forms within a storybook reading context. Following each of 12 stories, the children were required to spell and identify 12 novel written nonwords and then verbally produce and comprehend the spoken version of those words. Results indicated the children acquired initial specific phonological and orthographic representations. Spoken and written word learning skills were strongly associated and both were influenced by the words' linguistic regularities. Spoken word learning ability explained 62% of the variance on a spelling measure, whereas written word learning ability predicted 42% of the variance on a reading measure. The results provide evidence that beginning readers employ simultaneously a mutually shared learning mechanism that is sensitive to statistical regularities of words when engaged in the process of learning new spoken words and their written forms.  相似文献

The acquisition of a reading vocabulary for abstract and concrete words was examined in 62 second-grade children. Words had been learned as part of a basal reader program or as part of outside reading. Word recognition speed and reading accuracy were examined for abstract and concrete words using lexical decision and word naming tasks. The size of the concreteness effect was similar for both processing tasks. In neither task did concreteness influence reaction times, but abstract words were read with less accuracy than concrete words in both tasks. Further, these concreteness effects in reading accuracy were larger for words that were part of a basal reading program than for words acquired during free reading. We conclude that word meaning influences the entry of words at a time when children are developing a sizeable reading vocabulary.  相似文献

4 studies investigate how differential input affects preschoolers' abilities to learn novel color words. 3-, 4-, and 5-year-old children saw objects in novel shapes and colors and heard a novel color label for the object. Labels were presented through ostensive definition (e.g., "See, it's mauve"), corrective linguistic contrast (e.g., "See, it's not purple; it's mauve"), or an inclusion statement (e.g., "See, it's mauve; it's a kind of purple"). 4- and 5-year-old children interpreted the novel word as a shape term when ostensive information was provided but as a color term when additional information, either contrastive or inclusive, specified a relation between the novel term and a known label for that color. Furthermore, children who consistently interpreted the novel word as a color word tended to treat the novel and known labels as mutually exclusive color terms if they heard contrastive information, whereas they tended to treat the words as hierarchically related if they heard inclusion information. 3-year-olds generally did not make use of either type of information in determining the semantic domain of the novel word or the relation between terms.  相似文献

本文通过对表持续时段的for短语和汉语时量词语的比较，分析了汉语时量词语的不同用法，表明汉语时量词语并不总是等同于for短语。时量词语可以在动词前或的出现，除了在一些特殊结构外，动词前的时量词语一般不表示持续时段。只有持续词后的时量词语才是表持续意义的，瞬间动词后的时量词语表示的是动作行为完成后经历的时间。  相似文献

This article investigated children's fear responses to everyday exposure to the news in the absence of a recent crisis or major event. From March to May 2006, a survey was conducted of 218 kindergarten through 6th-grade children regarding their fright reactions to the news. Results showed that 35.3% of children reported being frightened by the news. Reporting on what frightened them in their own words, children most frequently mentioned natural disasters (24.7% of children frightened), followed by kidnappings (10.4% of children frightened), the Iraq War (7.8%), and burglaries (7.8%). A qualitative analysis suggests that some children have vivid memories of disturbing news content. The accessibility of television in children's households was not related to news exposure or fear. Implications for parental guidance and research methods are discussed.  相似文献

英汉两种语言对缤纷的颜色赋予了丰富多彩的文化涵义,从而构成了各具特色的颜色词汇。但由于不同的民族文化背景,英汉两种语言对同一颜色词可能会赋予不同的文化涵义。这就使得英汉两种语言在颜色词方面既有对应性的一面,又有非对应性的一面。  相似文献

In 2 studies, we compared the effectiveness of 4 different methods for acquiring initial reading vocabulary. Training emphasized similarity of word beginnings (onset plus vowel), similarity of word endings (rimes), phoneme segmentation and blending, or simple repetition of whole words. These 4 training regimes were compared with a control group given only regular classroom instruction. Beginning nonreaders acquired the trained words fastest in the onset and rime conditions, and most slowly in the whole word condition. Retention was excellent after 1 week and after 4 to 6 months, with no differences due to method of acquisition when only children who met the learning criterion were considered. Generalization to reading new words and nonwords was 40% to 50% on the first encounter for all children who acquired the entire word set during learning. In Experiment 2, the same pattern of results was obtained for delayed readers in Grade 2.  相似文献

Abstract

One purpose of this study was to determine whether a selected number of spelling series used high- frequency words for their lists when compared to a standard measure of word frequency. Another purpose was to determine whether students misspelled high-frequency words in their writing. Data collected from the spelling series were analyzed using a two-factor analysis of variance and the Tukey method of multiple comparisons. Data collected from children’s writing samples were analyzed using at test. Analysis showed differences in the number of high-frequency words among the series and within the grade levels. There also was a difference between the number of misspelled words in children’s writing at Grade 5 but not at Grade 3.  相似文献

The importance of language in the early childhood classroom cannot be overstated. All classroom activities that children engage in involve language to some extent. Those who have studied language know that it is among the most complex of human behaviors. Yet by the time children have reached the end of their third year of life, they have acquired all of the basic constructs of their native language (Brown, 1973). They have a vocabulary of literally thousands of words and comprehend many more words than they produce. They use different structures to make statements about objects or events, to ask questions, or to make requests. They use and understand small innuendos in language that may vary in meaning from context to context.Dominic F.

Although there has been growing interest in the development of emotion, a surprisingly small amount of research deals with the vocabulary children use to refer to emotions. In the present study, we examined differences in children's spontaneous use of emotion vocabulary during their naturally-occurring peer interactions and explored these differences in relation to their likability as assessed by their peers. Preschoolers were observed in their interactions with other children and their utterances containing emotion words were recorded. The content, form, and pragmatic function of these emotion words then were analyzed. It was found that with increasing age, emotion vocabulary became more differentiated and complex. Moreover, children who used a larger number of different emotion words, made more references to others' emotional states, and used emotion vocabulary for social functions, were more liked by their peers. Discussion focused on understanding young children's use of emotion vocabulary, the contributions it makes to the quality of their social interactions, and the implications of these for early educators.  相似文献

Previous studies of preverbal development have highlighted the recurrent difficulties experienced by deaf children in acquiring knowledge of the social rules and social skills pertaining to discourse. We expected cochlear implants in children with bilateral profound deafness to improve their use of verbal language, so that their communication skill profile resembled that of younger, hearing children. Using conversation samples taken from videos recorded every 6 months over a 2-year period, we monitored the development of communication skills in a group of 18 prelingually profoundly deaf children (mean implantation age, 3 years and 5 months). Results corroborated our hypothesis that the overall communication performances of children with cochlear implants improve, both quantitatively and qualitatively, as early as the first year post-implantation.  相似文献

Cross-language transfer of awareness of the structure of compound words was investigated among native speakers of Chinese who were learning English as a second language. Chinese fifth graders received instruction in the morphology of four types of compound words in either Chinese or English. They then completed both the Chinese and English versions of a compound word structure analogy task. Compared with children who received no instruction, children who received instruction in Chinese were able to transfer knowledge they had acquired of compound types in Chinese to comparable types in English. Reverse transfer from English to Chinese was found among children with high reading proficiency.  相似文献

When and how do infants learn color words? It is generally supposed that color words are learned late and with a great deal of difficulty. By examining infant language surveys in British English and 11 other languages, this study shows that color word learning occurs earlier than has been previously suggested and that the order of acquisition of color words is similar in related languages. This study also demonstrates that frequency and syllabic complexity can be used to predict variability in infant color word learning across languages. In light of recent evidence indicating that color categories have universal biological foundations, these findings suggest that infants’ experience and linguistic exposure drive their shift to culturally and linguistically mediated adult-like understandings of color words.  相似文献

The experimenter investigated the effect of semantic clues on the reading comprehension of deaf and hearing Israeli children. Two groups of students with prelingual deafness, and a hearing control group, were asked to read syntactically simple and syntactically relative sentences of varying semantic plausibility. Sixteen of the participants who were deaf (mean grade 6.9) had been trained orally, using spoken language as their principal means of communication at home and at school. Another 16 students with deafness (mean grade 6.9), all of them children of deaf parents, had acquired sign language as their primary language. The mean grade of the hearing control group was 6.5. The results suggest that, in contrast to the case with hearing individuals, reading comprehension in individuals with prelingually acquired deafness, regardless of communication background, is predominantly determined by the semantic processing of content words, with only minor attention given to the processing of the syntactic structure of the text.  相似文献
