Deaf and hard-of-hearing (DHH) children's ability to rapidly learn novel words through direct reference and through novel mapping (i.e., inferring that a novel word refers to a novel object) was examined. Ninety-eight DHH children, ranging from 27 to 82 months old, drawn from 12 schools in five states participated. In two tasks that differed in how reference was established, word-learning abilities were measured by children's ability to learn novel words after only three exposures. Three levels of word-learning abilities were identified. Twelve children did not rapidly learn novel words. Thirty-six children learned novel words rapidly but only in the direct reference task. Forty-nine children learned novel words rapidly in both direct reference and novel mapping tasks. These levels of word-learning abilities were evident in children who were in oral-only and in signing environments, in children with cochlear implants, and in deaf children of deaf parents. Children's word-learning abilities were more strongly correlated to lexicon size than age, and this relation was similar for children in these different language-learning environments. Acquisition of these word-learning abilities seems based on linguistic mechanisms that are available to children in a wide range of linguistic environments. In addition, the word-learning tasks offer a promising dynamic assessment tool. 相似文献

The extent to which cognitive development and abilities are dependent on language remains controversial. In this study, the analogical reasoning skills of deaf and hard of hearing children are explored. Two groups of children (deaf and hard of hearing children with either cochlear implants or hearing aids and hearing children) completed tests of verbal and spatial analogical reasoning. Their vocabulary and grammar skills were also assessed to provide a measure of language attainment. Results indicated significant differences between the deaf and hard of hearing children (regardless of type of hearing device) and their hearing peers on vocabulary, grammar, and verbal reasoning tests. Regression analyses revealed that in the group of deaf and hard of hearing children, but not in the hearing group, the language measures were significant predictors of verbal analogical reasoning, when age and spatial analogical reasoning ability were controlled for. The implications of these findings are discussed. 相似文献

Two representational abilities, expressive and receptive language and symbolic play, were assessed in multiple formats in hearing and deaf 2-year-old children of hearing and deaf mothers. Based on maternal report, hearing children of hearing and deaf mothers produced more words than deaf children of hearing mothers, hearing children of hearing mothers more words than deaf children of deaf mothers, and deaf children of deaf mothers more words than deaf children of hearing mothers. Based on experimenter assessments, hearing children in both groups produced and comprehended more words than deaf children in both groups. By contrast, no differences emerged among these groups in child solitary symbolic play or in child-initiated or mother-initiated child collaborative symbolic play; all groups also increased equivalently in symbolic play between solitary and collaborative play. Representational language and symbolic play were unrelated in hearing children of hearing mothers and in deaf children of deaf mothers, but the 2 abilities were associated in children in the 2 child/mother mismatched hearing status groups. These findings are placed in the context of a proposed developing modularity of verbal and nonverbal symbol systems, and the implications of hearing status in communicative exchanges between children and their mothers in diverse hearing and deaf dyads are explored. 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

From Here and Now to There and Then: The Development of Displaced Reference in Homesign and English 总被引：1，自引：0，他引：1
An essential function of human language is the ability to refer to information that is spatially and temporally displaced from the location of the speaker and the listener, that is, displaced reference . This article describes the development of this function in 4 deaf children who were not exposed to a usable conventional language model and communicated via idiosyncratic gesture systems, called homesign, and in 18 hearing children who were acquiring English as a native language. Although the deaf children referred to the nonpresent much less frequently and at later ages than the hearing children, both groups followed a similar developmental path, adding increasingly abstract categories of displaced reference to their repertoires in the same sequence. Care-givers in both groups infrequently initiated displaced reference, except with respect to communication about past events. Despite the absence of a shared linguistic code, the deaf children succeeded in evoking the non-present by generating novel gestures, by modifying the context of conventional gestures, and by pragmatic means. The findings indicate that a conventional language model is not essential for children to be able to extend their communication beyond the here and now. 相似文献

This study examined the ability of children in French immersion and English programs to analyze the internal structure of spoken words in relation to their early reading and spelling abilities in English. Thirty-two children in the first grade were given a modified version of the Auditory Analysis Test, and reading and spelling tasks that included both real words and non-words. Results indicated that French immersion children were more proficient than their English program peers at explicitly analyzing spoken words and that the groups did not differ when reading and spelling orthographically regular real words and non-words. The English program children performed better than their French program peers only when reading orthographically irregular English words. These results demonstrate that second language learning enhances metalinguistic awareness and help to explain why children in immersion programs do not experience long-term difficulty in acquiring English written language skills. 相似文献

There is ongoing debate about children's ability to use subsequently acquired language to describe preverbal experiences. This issue was addressed experimentally in this investigation using a novel paradigm. Two-year-old children who lacked color words were individually taught to activate a bubble machine by selecting a particular color of bubble solution. The children then participated in weekly, experimenter-provided activities that fostered their acquisition of the color labels. After 2 months, their ability to apply the newly acquired words in reporting the original event was assessed. A significant proportion of the children demonstrated verbal recall when prompted in the presence of physical reminders of the event. These findings indicate that some early, preverbal memories are translated into words at a later time. 相似文献

This article reports on a longitudinal study of reading progress in a group of five-year-old deaf children and a group of hearing controls. All children were prereaders at the beginning of the study and the IQ of the two groups were matched. The deaf children varied considerably on a number of measures, including implicit phonological awareness, oral ability, and familiarity with British Sign Language and fingerspelling. Overall, the deaf children made significantly less reading progress than their hearing peers over the first year of schooling, and they also scored significantly lower on the test of rime and onset awareness. However, considerable variation in the reading progress of the deaf children was positively correlated with oral skills, rime/onset awareness, and language comprehension. Language comprehension, itself, was positively correlated with signing and fingerspelling. The deaf children were assessed again one year later, when learning to read continued to be very delayed, and the pattern of correlation was essentially the same. The implications of these findings for the education of deaf children are discussed. 相似文献

This research identifies the extent to which different contexts shape and modify the language and behaviours of four people with acquired brain injury. Comparisons are made with factors which can influence the language acquisition of children with autism because it is postulated that children with autism also have a particular brain injury. The comparison does not end there as the criteria for effective management necessary to nourish the communication skills of both groups appears similar. The four contexts used to shape and evaluate the language of people with brain injury include their own home, a residential camp with maximum support and enriched activity, a post camp period with comparable support, followed by a return to their own home with very limited support. Measures of communication skills demonstrate the success of the enriched camp facility. This was characterised by planning, structured support, and expectation of success from the participants. Their motivation and ability to communicate generally far exceeded the communication skills that each person with brain injury demonstrated when organised activity and sustained support is not available. 相似文献

Using four traditional false-belief tasks, I investigated deaf children's age and expressive language skills in relation to their theory of mind development. The children's parents who signed reported on their own knowledge of a mental sign vocabulary. The results indicate age of the child to be strongly related to theory of mind development. Deaf children demonstrated an ability to pass the theory of mind assessment battery between the ages of 7 and 8 years, on average. In comparison, hearing children have consistently demonstrated the ability to perform such tasks between the ages of 4 and 5 years. Therefore, the results indicate deaf children are delayed by approximately 3 years in this cognitive developmental milestone. Expressive language skills of the children and sign language skills of the parents who signed were not found to be significantly related to the children's theory of mind development. 相似文献

It is unclear how children develop the ability to learn words incidentally (i.e., without direct instruction or numerous exposures). This investigation examined the early achievement of this skill by longitudinally tracking the expressive vocabulary and incidental word-learning capacities of a hearing child of Deaf adults who was natively learning American Sign Language (ASL) and spoken English. Despite receiving only 20% of language input in spoken English, the child's expressive vocabularies at 16 and 20 months of age, in each language, were similar to those of monolingual age-matched peers. At 16 months of age, the child showed signs of greater proficiency in the incidental learning of novel ASL signs than she did for spoken English words. At 20 months of age, the child was skilled at incidental word learning in both languages. These results support the methodology as it applies to examining theoretical models of incidental word learning. They also suggest that bilingual children can achieve typical vocabulary levels (even with minimal input in one of the languages) and that the development of incidental word learning follows a similar trajectory in ASL and spoken English. 相似文献

Adults create and update predictions about what speakers will say next. This study asks whether prediction can drive language acquisition, by testing whether 3- to 4-year-old children (n = 45) adapt to recent information when learning novel words. The study used a syntactic context which can precede both nouns and verbs to manipulate children's predictions about what syntactic category will follow. Children for whom the syntactic context predicted verbs were more likely to infer that a novel word appearing in this context referred to an action, than children for whom it predicted nouns. This suggests that children make rapid changes to their predictions, and use this information to learn novel information, supporting the role of prediction in language acquisition. 相似文献

聋校学生的书面语言能力主要通过语文课的教学获得。然而 ,经过多年语文课的学习 ,很多聋校学生的书面语言能力仍然很低下 ,成为提高文化知识的一大障碍。其根本原因在于 ,聋校的语文课基本上是参照普通中小学的语文课经过一定调整而来 ,但普通中小学学生是在已经获得了基本的口语能力之后开始语文课的学习。由于聋生缺乏相应的口语基础 ,现行语文课的教学并不能保证根本改变聋生书面语言水平低下的状况。发展聋生基本的语言能力应该通过语言课。在开始语文课的教学之前先开设语言课是解决问题的途径。语言课与语文课具有不同的性质和任务。语言课应选择适合自身任务的教学内容 ,并遵循适合聋校学生语言发展规律的教学原则 相似文献

The study examined the role of sign language and fingerspelling in the development of the reading and writing skills of deaf children and youth. Twenty-six deaf participants (13 children, 13 adolescents), whose first language was Chilean Sign Language (CHSL), were examined. Their dactylic abilities were evaluated with tasks involving the reading and writing of dactylic and orthographic codes. The study included three experiments: (a) the identification of Chilean signs and fingerspelled words, (b) the matching of fingerspelled words with commercial logos, and (c) the decoding of fingerspelled words and the mapping of these words onto the writing system. The results provide convergent evidence that the use of fingerspelling and sign language is related to orthographic skills. It is concluded that fingerspelling can facilitate the internal representation of words and serve as a supporting mechanism for reading acquisition. 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

This study examined the relationship between deaf preschoolers' language abilities and their play behavior. Twenty-nine deaf children aged three to five years were observed during outdoor free play throughout the school year. Their language abilities varied widely and did not correlate with age. On the basis of two language tests, they were divided into three language ability groups--high, middle, and low. Language ability was found to be related to several aspects of play and social interaction. The children with high language ability were more likely than the other children to play with two partners at the same time (i.e., engage in triadic interaction), to interact with teachers, to prefer to play with children of similar language ability, to use language, and to receive language from their partners. Most of these effects seemed to be due solely to differences between the children with high language ability and those in the other two groups. Children in the low and middle language ability groups behaved similarly. Language ability was not related to any other aspect of peer relations. Thus, the impact of language ability seems limited. These results, in conjunction with past research, suggest that, for the most part, deaf preschoolers' language and social skills develop independently from each other. 相似文献
