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

THE STUDY EXAMINED scaffolding interactions between deaf children and hearing mothers in which story reading was used as a tool to aid in the development of narrative comprehension and linguistic reasoning. The dyadic interactions were examined from the perspective of the theoretical works of Vygotsky (1934/1962, 1978, 1929/1981, 1960/1981). The sample group consisted of 7 dyads of hearing mothers and their deaf children ages 4.2 to 9.5 years. The mothers signed a story to their children. The dyadic interactions reflected the different levels of scaffolding and functioning within the zone of proximal development (Vygotsky, 1934/1962, 1978). The researchers found that story reading provides an excellent framework for both cognitive and emotional growth within the parent/child dyad. Mothers who engaged their children in mutual dialogue also used elaboration. This was reflected in their children's linguistic reasoning.  相似文献

The purpose of this article is to analyze the results of a study of the development of analogical reasoning in deaf children coming from two different linguistic environments (deaf children of deaf parents--sign language, deaf children of hearing parents--spoken language) and in hearing children, as well as to compare two groups of deaf children to a group of hearing children. In order to estimate the development of children's analogical reasoning, especially the development of their understanding of different logical relations, two age groups were singled out in each population of children: younger (9- and 10-year-olds) and older (12- and 13-year-olds). In this way it is possible to assess the influence of early and consistent sign-language communication on the development of the conceptual system in deaf children and to establish whether early and consistent sign-language communication with deaf children affects their mental development to the same extent as early and consistent spoken-language communication with hearing children. The children were given three series of analogy tasks based on different logical relations: (a) a series of verbal analogy tasks (the relations of opposite, part-whole, and causality); (b) a series of numerical analogy tasks (the relations of class membership, opposite, and part-whole); and (c) a series of figural-geometric analogy tasks (the relations of opposite and part-whole). It was found that early and consistent sign-language communication with deaf children plays an almost equivalent role in the development of verbal, numerical, and spatial reasoning by analogy as early and consistent spoken-language communication with hearing children.  相似文献

Deaf children's use of beliefs and desires in negotiation   总被引：3，自引：0，他引：3  
Although several studies have shown that deaf children demonstrated impaired performances on false-belief tasks, the children's belief understanding appeared intact when asked to explain emotions or behavior. However, this finding does not necessarily indicate a full-fledged theory of mind. This study aimed to investigate deaf children's negotiation strategies in false-belief situations, because situations that require negotiation provide a natural context with a clear motivational aspect, which might appeal more strongly to deaf children's false-belief reasoning capacities. The purpose of this study was to compare the reactions of 11- to 12-year-old deaf and hearing children to scenarios in which a mother, who is unaware of a change in the situation, threatens to block the fulfillment of the child's desire. The results showed that deaf children more often failed to correct the mother's false beliefs. In contrast with hearing children, who frequently left their own desires implicit, deaf children kept stressing their desires as a primary argument, even though the mother could be expected to be fully aware of these desires. Moral claims were used to the same extent by both groups. In general, deaf children more often used arguments that did not provide new information for their conversation partners, including repetitions of the same argument. The results were interpreted in terms of the special needs that are required by the hampered communication between deaf and hearing people as well as in terms of the ongoing discussion regarding theory-of-mind development in 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

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

Multiplicative reasoning is required in different contexts in mathematics: it is necessary to understand the concept of multipart units, involved in learning place value and measurement, and also to solve multiplication and division problems. Measures of hearing children's multiplicative reasoning at school entry are reliable and specific predictors of their mathematics achievement in school. An analysis of deaf children's informal multiplicative reasoning showed that deaf children under-perform in comparison to the hearing cohorts in their first two years of school. However, a brief training study, which significantly improved their success on these problems, suggested that this may be a performance, rather than a competence difference. Thus, it is possible and desirable to promote deaf children's multiplicative reasoning when they start school so that they are provided with a more solid basis for learning mathematics.  相似文献

Signposts to development: theory of mind in deaf children   总被引：5，自引：0，他引：5  
Possession of a "theory of mind" (ToM)--as demonstrated by an understanding of the false beliefs of others--is fundamental in children's cognitive development. A key question for debate concerns the effect of language input on ToM. In this respect, comparisons of deaf native-signing children who are raised by deaf signing parents with deaf late-signing children who are raised by hearing parents provide a critical test. This article reports on two studies (N = 100 and N = 39) using "thought picture" measures of ToM that minimize verbal task-performance requirements. These studies demonstrated that even when factors such as syntax ability, mental age in spatial ability, and executive functioning were considered, deaf late signers still showed deficits in ToM understanding relative to deaf native signers or hearing controls. Even though the native signers were significantly younger than a sample of late signers matched for spatial mental age and scores on a test of receptive sign language ability, native signers outperformed late signers on pictorial ToM tasks. The results are discussed in terms of access to conversation and extralinguistic influences on development such as the presence of sibling relationships, and suggest that the expression of a ToM is the end result of social understanding mediated by early conversational experience.  相似文献

A group of non-native, early signing deaf children between the ages of 7 and 11 years were tested on a referential communication task. A group of hearing children matched for sex and mental and chronological age were also included in the study. The aim was to study the deaf children's ability to take another persons perspective in a task that resembled a real-life communicative situation to a higher extent than the standard theory of mind (ToM) tasks. A further aim was to investigate the possible importance of a number of background variables such as mental and chronological age, working memory, and false-belief attribution. Results show that the hearing children outperformed the deaf children on the referential communication task and that results were highly correlated with both chronological and mental age, as well as with working memory. There was a positive, but not significant, correlation between false belief and success on the referential communication task. This is an indication that the two tasks tap different abilities and that false belief might be necessary, but not sufficient in order to be skilled in the art of referential communication. The possible role of working memory in the referential communication task is also discussed. The results support the hypothesis of the importance of early talk about mental states for the later development of ToM abilities.  相似文献

This study investigated deaf children's "security of attachment" relationships with their hearing parents and the relationship of parental attitudes toward deafness. Subjects included 30 deaf children and their hearing parents. The children ranged in age from 20 to 60 months. Instruments used included the Attachment Q-Set, the Attitudes to Deafness Scale, and parental interviews. As a group there were no differences between security of attachment scores of deaf children toward either of their parents; however, there were marked differences within individual dyads of mother-child/father-child relationships. In addition, negative correlations were found between parents' attitudes towards deafness scores and their deaf children's security of attachment scores. Implications for the field include the importance of inclusion of fathers in attachment studies and fathers' active participation in early intervention programs. The relationship between parental attitudes toward their children's disability (deafness) and attachment relationship provides further evidence for the critical role of early intervention in the development of children with special needs.  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

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

This study investigates the relationship between theory of mind (ToM) skills in deaf children and input from their hearing mothers. Twenty-two hearing mothers and their deaf children (ages 4-10 years) participated in tasks designed to elicit talk about the mind. The mothers' mental state talk was compared with that of 26 mothers with hearing children (ages 4-6 years). The frequency of mothers' mental talk was correlated with deaf children's performance on ToM tasks, after controlling for effects of child language and age. Maternal sign proficiency was correlated with child language, false belief, and mothers' talk about the mind. Findings are discussed in relation to experiential accounts of ToM development and roles of maternal talk in children's social understanding.  相似文献

Psychosocial factors, including socioemotional well-being, peer relationships, and social inclusion with hearing and deaf peers, are increasingly becoming a focus of research investigating children with cochlear implants. The study reported here extends the largely quantitative findings of previous research through a qualitative analysis of interviews with parents, teachers, and pediatric cochlear implant users themselves in three eastern states of Australia. We interviewed 24 parents, 15 teachers, and 11 children and adolescents. The findings displayed commonalities across the three groups of participants, indicating positive experiences around the children's psychosocial development with their cochlear implants, but also ongoing difficulties communicating in groups of people and problems related to social skills. Some children had little contact with other deaf children (with or without cochlear implants) despite parents and teachers perceiving such contact beneficial. Children attending schools where there were other deaf children valued friendships with both deaf and hearing peers. Adolescence was a particularly difficult time for some as they struggled with feelings of self-consciousness about their deafness and external cochlear implant equipment and worries around friendships, dating, and their future place in the world. Recommendations for practice and further research are made.  相似文献

This article focuses on nonsigning hearing parents of deaf children who share the goals of bilingual-bicultural (BiBi) programs for their child, opt for their home language to be their deaf child's first language (L1), and have questions about communication options (e.g., oral methods, manually coded English [MCE] systems, or Cued Speech) for conveying that language. We present research findings related to the effectiveness of MCE systems and Cued Speech for conveying English and developing deaf children's reading abilities. We compare the cueing of English and the signing of MCE systems in terms of theoretical and practical advantages. Finally, we suggest research needs.  相似文献

Two groups of deaf children, aged 8 and 14 years, were presented with a number of tasks designed to assess their reliance on phonological coding. Their performance was compared with that of hearing children of the same chronological age (CA) and reading age (RA). Performance on the first task, short-term recall of pictures, showed that the deaf children's spans were comparable to those of RA controls but lower than CA controls. For the older deaf children, short-term memory span predicted reading ability. There was no clear evidence that the deaf children were using phonological coding in short-term memory when recall of dissimilar items was compared with recall of items with similarly sounding names. In the second task, which assessed orthographic awareness, performance of the deaf children was similar to that of RA controls although scores predicted reading level for the deaf children but not the hearing. The final task was a picture spelling test in which there were marked differences between the deaf and hearing children, most notably in the number of spelling refusals (which was higher for the deaf children in the older group than their RA controls) and the percentage of phonetic errors (which was considerably lower for both groups of deaf children than for any of the hearing controls). Overall these results provide support for the view that deaf children place little reliance on phonological coding.  相似文献

Eleven 18-month-old children with profound prelingual hearing loss were video-recorded in a free-play session with their mothers. Five of the mothers were profoundly deaf and fluent users of British Sign Language (BSL) or Auslan. The other six were hearing and had enrolled in a signing program. Ten-minute segments from each session were analyzed to determine the number of switches in attention shown by each child. Switches in attention were subdivided into three categories: spontaneous (where the child spontaneously looked to the mother); responsive (where the child responded to some maternal action such as moving an object); and elicited (where the mother made a direct attempt to gain the child's attention. Failed attempts to gain attention were also noted. A comparison of deaf and hearing mothers revealed no difference in the proportion of spontaneous or responsive switches in attention shown by their children. Responsive switches were by far the most frequent category for both groups, but these most commonly focused on objects and did not provide an opportunity for maternal signing. Successful perception of signing typically followed from spontaneous or elicited attentional switches. Deaf mothers were generally more insistent on their children turning to look at them, and they were more successful in eliciting attentional switches although they also had more failed attempts. These overall differences between the two groups were overshadowed by large individual differences within the groups. Within the sample there were both deaf and hearing mothers who achieved successful signed communication with their children.  相似文献

Young deaf children use their vision to gather both language input and information about the environment. This dual requirement greatly complicates conversational turn-taking for the children and their parents, particularly when interaction centers on a visual focus such as a book. Data are presented here on the onset and maintenance of visual attention to signing in three profoundly deaf children, ages 2;9-3;7 years, while interacting with their hearing mothers about a story told through pictures. The data indicate that the children's visual attention in this situation was quite variable, although all of them experienced problems with their need to focus simultaneously on two sources of information: the mother's signs and the picture book. Suggestions for developing visual turn-taking skills are made, based on the research on first-language acquisition and the interactions of deaf mothers with their children.  相似文献

Egocentric language is a generalization of Piaget's egocentric speech concept (1926/1969) investigated by Vygotsky (1962). Behaviors of eight children ages 2 to 5 years with profound congenital deafness were analyzed using six classes of egocentric language: motor reaction activity, silent lips articulation, murmur, oral-facial mimics, body expression, and vocalization. No child had received oral or sign language training. All attended videotaped play sessions. Events in which children engaged in "dialogue" with themselves or a toy, while pursuing a specific solution, were observed. Such extralinguistic behavior moves the thinking process toward problem solving like that of hearing children. Consequently, teachers should not interrupt when a deaf child is playing with or signing or vocalizing to a toy, because this behavior may be the manifestation of a reflexive moment and the generator of a decision process fundamental for cognitive development. Vocalization by a deaf child does not indicate willingness to speak; it merely manifests symbolic reasoning. Silent lips articulation and oral-facial mimics have the same effect and can also be interpreted.  相似文献
