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

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

Twelve parents of young deaf children were recorded sharing books with their deaf child--six from families using British Sign Language (BSL) and six from families using spoken English. Although all families were engaged in sharing books with their deaf child and concerned to promote literacy development, they approached the task differently and had different expectations in terms of outcome. The sign bilingual families concentrated on using the book to promote BSL development, engaging in discussion around the book but without referring to the text, whereas the spoken language families were focused on features of the text and less inclined to use the book to promote wider knowledge. Implications for early intervention and support are drawn from the data. 相似文献

The study assessed Theory of Mind (ToM) abilities in a group of oral deaf children and in their hearing mothers using a battery of ToM tasks. It also investigated the connection between mother and child in ToM performance. Participants were: 17 oral deaf children (aged 5 to 14 years) were paired by gender, age, and mental age with 17 hearing children; 17 hearing mothers of deaf children and 17 hearing mothers of hearing children. Compared to the hearing children, the deaf children faced difficulties in all ToM tests, and the hearing mothers of the deaf children were less capable than the mothers of the hearing children in all the ToM tests. Further, a specific ToM interaction model was found between the hearing mothers and the deaf children. The results confirmed ToM poor performance faced by the oral deaf children, showed the ToM level of hearing mothers of deaf children, and the ToM style of hearing mothers–deaf children dyads. Also, findings underline some educational implications related to the socio-relational origin of the ToM deficit in oral deaf children. 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

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

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

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

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

The relationship between language and executive function (EF) and their development in children have been the focus of recent debate and are of theoretical and clinical importance. Exploration of these functions in children with a peripheral hearing loss has the potential to be informative from both perspectives. This study compared the EF and language skills of 8- to 12-year-old children with cochlear implants (n = 22) and nonimplanted deaf children (n = 25) with those of age-matched hearing controls (n = 22). Implanted and nonimplanted deaf children performed below the level of hearing children on tests assessing oral receptive language, as well as on a number of EF tests, but no significant differences emerged between the implanted and nonimplanted deaf groups. Language ability was significantly positively associated with EF in both hearing and deaf children. Possible interpretations of these findings are suggested and the theoretical and clinical implications considered. 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 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

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

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

Written texts produced by 10 Italian deaf native signers in four different writing tasks were analyzed. Data analysis focused on linguistic and orthographic nonstandard forms. The written production of deaf subjects with deaf parents (DD) was compared to the written production in two control groups: a group of 10 hearing subjects with deaf parents (HD) and a group of 10 subjects who have had no contact with deaf people or sign language (HH). The results duplicate findings from previous studies. Deaf subjects display a pattern of selective difficulty with Italian grammatical morphology, especially with free-standing function words. The four different writing tasks used in the present study yield results indicating that text type does influence our assessment of deaf writing abilities. A comparison of the texts written by deaf native signers with those of two hearing groups confirms the view that difficulties in the acquisition of written Italian are best explained by deafness itself, not by the influence of a previously acquired Sign Language, and that the specific difficulties with grammatical morphology displayed by our deaf subjects cannot be attributed solely to their limited experience with written Italian. 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

Communication mode and the processing of printed words: evidence from readers with prelingually acquired deafness 总被引：6，自引：0，他引：6
Miller P 《Journal of deaf studies and deaf education》2002,7(4):312-329
The aim of this study was to elucidate how the primary communication background of prelingual deafened readers affects the way they mediate the recognition of written words. A computer-controlled research paradigm (a semantic decision task) asking for the categorization of familiar Hebrew nouns was used to investigate the participants' sensibility to phonological and orthographic manipulations in the target stimuli. Two groups of readers with hearing impairments and a hearing control group participated in the study. Twenty-seven of the participants with deafness (mean grade 6.9) were raised by hearing parents advocating a strict oral approach at home and at school. For an additional 22 students who were deaf (mean grade 6.9), the majority of them children of deaf parents, Israeli Sign Language was the preferred means of communication. The mean grade of the 39 participants in the hearing control group was 6.5. Findings indicate that both the hearing participants and the participants with prelingual deafness who were trained to communicate orally recoded visually presented target words phonologically. No such evidence was found for participants with deafness who were native signers. Although participants from signing backgrounds seemed to generate nonphonological representations of written words, there was no evidence that for them, the absence of recoding to phonology detrimentally affected on their ability to process such representations flexibly. In all, findings suggest a causal link between an individual's processing strategy for some written words and the modal nature of his or her primary language. 相似文献

The effects of sign language use on cognitive processes of second-generation deaf children were investigated through an intensional categorization task. A forced-choice paradigm was used to examine children's selections of schematic and categorical alternatives as associations to targets that differed in their related sign language characteristics. The results obtained from 48 deaf and hearing 6-year-olds suggest some differences in the categorization abilities and cognitive flexibility between the two groups of children. These differences appear to be explainable in terms of linguistic variables underlying French Sign Language. 相似文献

This article presents a study that examined the impact of visual communication on the quality of the early interaction between deaf and hearing mothers and fathers and their deaf children aged between 18 and 24 months. Three communication mode groups of parent-deaf child dyads that differed by the use of signing and visual-tactile communication strategies were involved: (a) hearing parents communicating with their deaf child in an auditory/oral way, (b) hearing parents using total communication, and (c) deaf parents using sign language. Based on Loots and colleagues' intersubjective developmental theory, parent-deaf child interaction was analyzed according to the occurrence of intersubjectivity during free play with a standard set of toys. The data analyses indicated that the use of sign language in a sequential visual way of communication enabled the deaf parents to involve their 18- to 24-month-old deaf infants in symbolic intersubjectivity, whereas hearing parents who hold on to oral-only communication were excluded from involvement in symbolic intersubjectivity with their deaf infants. Hearing parents using total communication were more similar to deaf parents, but they still differed from deaf parents in exchanging and sharing symbolic and linguistic meaning with their deaf child. 相似文献
