This study investigated whether deafness contributes to enhancement of visual spatial cognition independent of knowledge of a sign language. Congenitally deaf school children in India who were born to hearing parents and were not exposed to any sign language, and matched hearing controls, were given a test of digit span and five tests that measured visual spatial skills. The deaf group showed shorter digit span than the hearing group, consistent with previous studies. Deaf and hearing children did not differ in their performance on the visual spatial skills test, suggesting that deafness per se may not be a sufficient factor for enhancement of visual spatial cognition. Early exposure to a sign language and fluent sign skills may be the critical factors that lead to differential development of visual spatial skills in deaf people.  相似文献

Deaf children who are native users of American Sign Language (ASL) and hearing children who are native English speakers performed three working memory tasks. Results indicate that language modality shapes the architecture of working memory. Digit span with forward and backward report, performed by each group in their native language, suggests that the language rehearsal mechanisms for spoken language and for sign language differ in their processing constraints. Unlike hearing children, deaf children who are native signers of ASL were as good at backward recall of digits as at forward recall, suggesting that serial order information for ASL is stored in a form that does not have a preferred directionality. Data from a group of deaf children who were not native signers of ASL rule out explanations in terms of a floor effect or a nonlinguistic visual strategy. Further, deaf children who were native signers outperformed hearing children on a nonlinguistic spatial memory task, suggesting that language expertise in a particular modality exerts an influence on nonlinguistic working memory within that modality. Thus, language modality has consequences for the structure of working memory, both within and outside the linguistic domain.  相似文献

The ability to attribute false beliefs (i.e., demonstrate theory of mind) by 155 deaf children between 5 and 8 years of age was compared to that of 39 hearing children ages 4 to 6. The hypotheses under investigation were (1) that linguistic features of sign language could promote the development of theories of mind and (2) that early exposure to language would allow an easier access to these theories. Deaf children were grouped according to their communication mode and the hearing status of their parents. The results obtained in three false belief tasks supported the hypotheses: effective representational abilities were demonstrated by deaf children of deaf parents, whereas those born to hearing parents appeared delayed in that regard, with differences according to their communication mode.  相似文献

Deaf and hard of hearing children have shown delays and difficulties in pragmatic behaviors due to insufficient exposure to common daily discourse and underlying impoverishment in all components of language development. In a study in a school district in a southeastern U.S. state, the researchers investigated the relationship between sociolinguistic pragmatic competence in 81 deaf and hard of hearing students and these students' degree of hearing loss, communication mode, and degree of success in general education. Two measures, one devised by the state's department of education and one developed within the local school system, were used: the Criterion-Referenced Competency Test (Georgia Department of Education, 2000) and the Socio-Pragmatic Skills Checklist for Deaf and Hard of Hearing Students (Cobb County School District, 1997). The researchers found that whether the students used spoken language or signed language, socio-pragmatic language had a high, positive correlation with academic outcomes.  相似文献

On-line comprehension of American Sign Language (ASL) requires rapid discrimination of linguistic facial expressions. We hypothesized that ASL signers' experience discriminating linguistic facial expressions might lead to enhanced performance for discriminating among different faces. Five experiments are reported that investigate signers' and non-signers' ability to discriminate human faces photographed under different conditions of orientation and lighting (the Benton Test of Facial Recognition). The results showed that deaf signers performed significantly better than hearing non-signers. Hearing native signers (born to deaf parents) also performed better than hearing nonsigners, suggesting that the enhanced performance of deaf signers is linked to experience with ASL rather than to auditory deprivation. Deaf signers who acquired ASL in early adulthood did not differ from native signers, which suggests that there is no 'critical period' during which signers must be exposed to ASL in order to exhibit enhanced face discrimination abilities. When the faces were inverted, signing and nonsigning groups did not differ in performance. This pattern of results suggests that experience with sign language affects mechanisms specific to face processing and does not produce a general enhancement of visual discrimination. Finally, a similar pattern of results was found with signing and nonsigning children, 6-9 years old. Overall, the results suggest that the brain mechanisms responsible for face processing are somewhat plastic and can be affected by experience. We discuss implications of these results for the relation between language and cognition.  相似文献

Deaf individuals usually face more challenges in reading and writing, because they are often deprived of adequate spoken input from their infancy. Research on the language features of deaf individuals’ writing is abundant. However, their language structures have as yet been unexplored. In order to address this subject, this article uses the holistic approach of complex network theory. This study builds three syntactic dependency networks, the intent being to capture the macroscopic linguistic features in writing of deaf individuals. Three networks are constructed: one is created from a treebank of texts produced by deaf individuals, and the other two are created from two treebanks of spoken and written language samples produced by hearing people. A dependency‐based theory of syntax is used. The results indicate that the language system of individuals with deafness is structurally similar to that of hearing people, especially to that of their spoken language, but individuals with deafness tend to have lower language proficiency in both syntactic and lexical aspects. The rigid use of function words and less diversity of vocabulary might be part of the reason for the observed differences.  相似文献

聋童智力研究述评   总被引:1,自引:0,他引:1  
在早期,人们普遍认为聋童获取信息的听觉渠道的损伤,会使其语言活动受到限制,造成儿童智力发展水平低下。但后来的研究发现,智力机能是独立于语言的,因此耳聋并不能直接导致智力发展的落后。一系列研究表明,聋童非言语智力测验的成绩与健听儿童大致相等,使用手语的聋童在各种视觉空间任务上显示出优于健听儿童的能力;聋童智力测验的结果和测验工具、测验实施方式有关;遗传、社会、教育等因素也对聋童的智力发展产生影响。  相似文献

听力正常家庭和聋人家庭中聋童心理理论的发展   总被引:3,自引:0,他引:3  
聋童能否正确理解他人心理状态直接影响其正常的社会交往。已有研究表明,听力正常家庭中的聋童心理理论水平低于正常儿童,但随其语言发展和年龄增长而逐步提升。聋人家庭中的聋童心理理论处于正常水平,并随年龄增长而成熟。尽管存在心理表征能力发展的迟滞,听力正常家庭中的聋童能在一定程度上理解图片对于现实的错误表征。研究结果提示正常的社交情境可能与聋童的心理理论发展有关。  相似文献

In recent years, empowerment and resource orientation have become vital guidelines for many of the sciences. For the field of deaf education, it is also highly important to look carefully at these guidelines if we are to acquire a better understanding as regards both the situation of the parents involved and the development of the deaf and hard of hearing children themselves. A resource-oriented approach to deaf education has therefore proved especially helpful. If both the theoretical and practical aspects of educating deaf and hard of hearing children are to benefit, research on parental experience with deafness and research on the socioemotional development of the children must always be combined and studied in the context of resource availability. In a study of 213 mothers and 213 fathers of deaf and hard of hearing children, we used an array of different questionnaires (PSI, SDQ, SOC, F-SozU, etc.) to examine the correlation between parental resources, sociodemographic variables, parental stress experience, and child socioemotional problems by way of a path analysis model. The results show that high parental stress is associated with frequent socioemotional problems in the children, thus emphasizing the importance of a resource-oriented consulting and support strategy in early intervention, because parental access to personal and social resources is associated with significantly lower stress experience. Child development seems to profit enormously from a resource-oriented support concept. In addition, the results confirm two earlier findings: parents with additionally handicapped children are especially stressed and the child's communicative competence makes for a more sound prediction than its linguistic medium (spoken language or sign). The path models for mothers and fathers agree in all essential factors. The results are discussed with a view to their meaning for pedagogical practice, and recommendations for further research are given (longitudinal data, more representative samples, cochlear implant).  相似文献

Parents with deaf children face many challenges in making educational choices, developing language and a sense of belonging. Other key aspects of life including concept development and social competency are also critical decision points faced by parents. Developing language, whether it is through spoken or signed modalities, is of utmost importance during the formative years and for many families with deaf children, there are no prior experiences with deafness, American Sign Language, Deaf culture, or the deaf community. This study aims to understand the educational and familial experiences of older deaf citizens by examining the meaning of being deaf and members of biological and cultural families, and the concern for education of young deaf children as constructed by deaf senior citizens from both deaf and hearing families. For the purpose of obtaining both childhood and educational experiences of older deaf citizens and examining what advice they would offer to families of today with deaf children, a qualitative design was implemented in which 13 participants participated in focus group and individual interviews. Themes that emerged from the data include, but are not limited to, community-based learning, the value of communication, involvement with other deaf individuals, importance of family communication and signing, sibling involvement and including deaf children as true members of a family. One recommendation made by the deaf senior adults was that families with deaf children engage with deaf seniors more frequently as a valuable resource.  相似文献

We examined communication between hearing mothers and their deaf or hearing children longitudinally at child-ages 22 months and 3 years. Specifically, we analyzed both the effects of child deafness and developmental change on pragmatic and dialogic characteristics of communication. From 22 months to 3 years, deaf and hearing children's communicative skills improved similarly along some dimensions: as they grew older, both deaf and hearing children increased the amount they communicated, became increasingly responsive to their mothers' attentional focus, and were responsible for initiating a higher proportion of the dyads' conversations. On the other hand, deaf children were less skilled at maintaining topics, and the pragmatic function of their communication was more likely to be unclear compared to hearing children. Deaf children were also more likely to direct their mothers and less likely to ask questions than hearing children. Communication by hearing mothers was primarily examined to determine the degree to which they controlled the interactions. Overall, mothers of deaf children were only more controlling along one dimension. Mothers of deaf children used more response controls than mothers of hearing children. However, the majority of measures suggested they did not exert more topic or turn-taking controls than did mothers of hearing children. In addition, mothers of deaf and hearing children seemed equally sensitive to their children's communication abilities. Communication by mothers of both deaf and hearing children changed in similar ways as their children developed. Most of the differences in communication by mothers of deaf and hearing children seemed attributable to the deaf children's linguistic delays. The results suggest that intervention efforts should be focused on fostering linguistic development and not general communication skills or changing maternal conversational control.  相似文献

The signed and spoken language produced by 14 mothers to their 18-month-old children during free play was analyzed. All the children had profound prelingual deafness. Seven of the mothers were profoundly deaf and fluent users of British Sign Language (BSL) or Auslan. The other seven were hearing and had enrolled in a signing program. Maternal signed utterances were classified according to whether they were made in the child's line of sight and whether they had a salient context; that is, they referred to an object or event at the child's current focus of attention. Spoken utterances were coded by word length. Comparisons between the two groups showed that both deaf and hearing mothers produced a majority of single-sign utterances (rather than utterances containing two or more signs). Deaf mothers also produced a majority of single-word spoken utterances, whereas the hearing mothers produced a significantly greater proportion of multiword utterances. As predicted, deaf mothers were more successful than hearing mothers in presenting signed utterances with a salient context that were visible to their children. Across the group as a whole, the total number of visible and salient signed utterances produced in 10 minutes was positively correlated with the total number of occasions on which mothers successfully redirected their child's attention or the child spontaneously turned to look at the mother. This suggests that deaf children who are visually attentive to their mothers receive a greater number of visible signed utterances with a salient context. I argue that this provides a more secure context for early language development.  相似文献

Potential effects of auditory and other communicative experience on development of visual attention were investigated for four groups of infants at 9, 12, and 18 months of age. Participants included 20 deaf infants with deaf mothers, 19 deaf infants with hearing mothers, 21 hearing infants with hearing mothers, and 20 hearing infants with deaf mothers. Infants' hearing status alone did not associate with patterns of visual attention. Deaf infants with deaf mothers showed significantly longer times in the most advanced attention state (coordinated joint) than did deaf infants with hearing mothers. However, other aspects of experience were associated with group differences. Both deaf and hearing children with deaf mothers who signed spent more time onlooking (or watching) their mothers than did children (deaf or hearing) with hearing mothers. Hearing children with hearing mothers spent more time looking at objects than did children with deaf mothers. Despite these differences in time in various attention states, the general trajectory of development of each of the attention states was similar across groups. Results indicate that early visual attention is associated with and potentially influenced by a complex interaction of maturation, communicative experiences, and other developing skills.  相似文献

For over 25 years in some countries and more recently in others, bilingual education involving sign language and the written/spoken vernacular has been considered an essential educational intervention for deaf children. With the recent growth in universal newborn hearing screening and technological advances such as digital hearing aids and cochlear implants, however, more deaf children than ever before have the potential for acquiring spoken language. As a result, the question arises as to the role of sign language and bilingual education for deaf children, particularly those who are very young. On the basis of recent research and fully recognizing the historical sensitivity of this issue, we suggest that language planning and language policy should be revisited in an effort to ensure that they are appropriate for the increasingly diverse population of deaf children.  相似文献

Language facility and theory of mind development in deaf children   总被引:3,自引:0,他引:3  
Deaf children with signing parents, nonnative signing deaf children, children from a hearing impaired unit (HIU), and oral deaf children were tested on three first-order theory of mind (ToM) tasks--a subset was also given a second-order task (Perner & Wimmer, 1985). A British Sign Language (BSL) receptive language task (Herman, Holmes, & Woll, 1999) and four nonverbal executive function tasks were also administered. The new BSL task allowed, for the first time, the receptive language abilities of deaf children to be measured alongside ToM abilities. Hearing children acted as controls. These children were given the same tasks, except the British Picture Vocabulary Scale was substituted for the BSL task. Language ability correlated positively and significantly with ToM ability, and age was correlated with language ability for both the deaf and hearing children. Age, however, underpinned the relationship between ToM and language for deaf children with signing parents and hearing children but not for nonnative signing, HIU, or oral deaf children. Executive function performance in deaf children was not related to ToM ability. A subset of hearing children, matched on age and language standard scores with signing deaf children, passed significantly more ToM tasks than the deaf children did. The findings are discussed with respect to the hypotheses proposed by Peterson and Siegal (1995, 2000) and Courtin (2000).  相似文献

The performance of young deaf children in spatial and temporal number tasks   总被引:2,自引:0,他引:2  
Deaf children tend to fall behind in mathematics at school. This problem may be a direct result of particular experiences in the classroom; for example, deaf children may find it hard to follow teachers' presentations of basic, but nevertheless quite abstract, mathematical ideas. Another possibility is that the problem starts before school: They may either be worse than hearing children at early, nonlinguistic number representations, they may be behind in learning the culturally transmitted number string, or both. This may result in deaf children failing to develop informal problem-solving strategies, which prepare most children for the more formal learning of number and arithmetic that they will have to do at school. We compared 3- and 4-year-old deaf and hearing children's ability to remember and to reproduce the number of items in a set of objects. In one condition, we presented all the items together in a spatial array; in another, we presented them one at a time in a temporal sequence. Deaf children performed as well as the hearing children in the temporal tasks, but outperformed their hearing counterparts in the spatial task. These results suggest that preschool deaf children's number representation is at least as advanced as that of hearing children, and that they are actually better than hearing children at representing the number of objects in spatial arrays. We conclude that deaf children's difficulties with mathematical learning are not a consequence of a delay in number representation. We also conclude that deaf children should benefit from mathematical instruction that emphasizes spatial representation.  相似文献

ABSTRACT

This study aims to compare word spelling outcomes for French-speaking deaf children with a cochlear implant (CI) with hearing children who matched for age, level of education and gender. A picture written naming task controlling for word frequency, word length, and phoneme-to-grapheme predictability was designed to analyze spelling productions. A generalized linear mixed model on the percentage of correct spelling revealed an effect of participant’s reading abilities, but no effect of hearing status. Word frequency and word length, but not phoneme-to-grapheme predictability, contributed to explaining the spelling variance. Deaf children with a CI made significantly less phonologically plausible errors and more phonologically unacceptable errors when compared to their hearing peers. Age at implantation and speech perception scores were related to deaf children’s errors. A good word spelling level can be achieved by deaf children with a CI, who nonetheless use less efficiently the phoneme-to-grapheme strategy than do hearing children.  相似文献

OBJECTIVE: North American studies conclude that deaf children may have a 2-3 times greater risk of sexual abuse than hearing children. No comparative studies are available in the Nordic countries. The present study was initiated to estimate the prevalence of childhood sexual abuse among deaf children in Norway, describe the nature of the abuse, and to examine risk factors. METHOD: A self-administered questionnaire was sent in 1999 to all 1150 adult deaf members of the Norwegian Deaf Register. The Deaf Register includes all deaf Norwegians. The questionnaire, which was also available videotaped in sign language, was an adapted version of a questionnaire used in a Norwegian survey among the general adult population in 1993. The results from this earlier study were used as a comparison group. RESULTS: Deaf females aged 18-65 who lost their hearing before the age of 9 (N = 177) reported sexual abuse with contact before the age of 18 years more than twice as often as hearing females, and deaf males more than three times as often as hearing males. The abuse of the deaf children was also more serious. Very few cases were reported to parents, teachers, or authorities. CONCLUSIONS: Deaf children are at greater risk of sexual abuse than hearing children. The special schools for the deaf represent an extra risk of abuse, regardless of whether the deaf pupils live at home or in boarding schools.  相似文献

Theory-of-mind (ToM) abilities were studied in 176 deaf children aged 3 years 11 months to 8 years 3 months who use either American Sign Language (ASL) or oral English, with hearing parents or deaf parents. A battery of tasks tapping understanding of false belief and knowledge state and language skills, ASL or English, was given to each child. There was a significant delay on ToM tasks in deaf children of hearing parents, who typically demonstrate language delays, regardless of whether they used spoken English or ASL. In contrast, deaf children from deaf families performed identically to same-aged hearing controls (N=42). Both vocabulary and understanding syntactic complements were significant independent predictors of success on verbal and low-verbal ToM tasks.  相似文献

Assessment is a major part of the United States schooling system. Legal requirements make assessment a large part of practitioner responsibilities. The significance of assessment is, even more, the case for special populations such as bilingual hearing and Deaf and Hard of Hearing students, groups that are often the target of concern for English language development delays, differences, and/or disorders. In this article, we discuss the issues around assessing the language of Deaf and Hard of Hearing bilingual students in the United States. We highlight parallels between Deaf Education and hearing bilingual education in regard to language assessment, as well as discuss important distinctions such as the placement of Deaf Education within Special Education and working with two or more language modalities (e.g., signed, spoken, and written). In addition, alternative language assessment practices are discussed. We close this article by proposing ways for practitioners to satisfy legal and field mandates to assess Deaf and Hard of Hearing students while also applying best practices for assessing language skills in bilingual populations.  相似文献
