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 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

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

Theory of mind development in deaf children: a nonverbal test of false-belief understanding 总被引：4，自引：0，他引：4
Our aim in this study was to investigate whether previous findings pointing to a delay in deaf children's theory of mind development are replicated when linguistic demands placed on the deaf child are minimized in a nonverbal version of standard false-belief tasks. Twenty-four prelingually deaf, orally trained children born of hearing parents were tested with both a verbal and a nonverbal version of a false-belief task. Neither the younger (range: 4 years 7 months-6 years 5 months) nor the older (range: 6 years 9 months-11 years 11 months) children of the final sample of 21 children performed above chance in the verbal task. The nonverbal task significantly facilitated performance in children of all ages. Despite this facilitation, we observed a developmental delay: only the older group performed significantly above chance in the nonverbal false-belief task, even though the younger children were at the average age when hearing children normally pass standard false-belief tests. We discuss these findings in light of the hypothesis that language development and conversational competence are crucial to the acquisition of a theory of mind. 相似文献

The study attempted to identify characteristics of individual differences in sign language abilities among deaf children. Connections between sign language skills and rapid serial naming, hand motor skills, and early fluency were investigated. The sample consisted of 85 Finnish deaf children. Their first language was sign language. Simple correlations and multiple linear-regression analysis demonstrated the effect of early language development and serial hand movements on sign language abilities. Other significant factors were serial fingertapping and serial naming. Heterogeneity in poor sign language users was noted. Although identifying learning disorders in deaf children is complicated, developmental difficulties can be discovered by appropriate measurements. The study confirmed the results of earlier research demonstrating that the features of deaf and hearing children's learning resemble each other. Disorders in signed and spoken languages may have similar bases despite their different modalities. 相似文献

To This is a 1 test per thousand learn more about normal language development in deaf children, we have developed the MacArthur Communicative Development Inventory for American Sign Language (ASL-CDI), a parent report that measures early sign production. The ASL-CDI is an inventory of sign glosses organized into semantic categories targeted to assess sign language skills in children ages 8 to 36 months. The ASL-CDI uses a recognition format in which parents check off signs that their child produces. The form has demonstrated excellent reliability and validity. To date, normative data have been collected from 69 deaf children with deaf parents who are learning sign language as a first language. We discuss the development of the ASl-CDI and preliminary cross-sectional and longitudinal findings from this early data collection with particular focus on parallels with spoken language acquisition. We also discuss the acquisition of first signs, negation, wh-questions, and fingerspelling with developmental patterns provided based on age, as well as vocabulary size. 相似文献

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

聋儿心理理论的发展及其培养 总被引：1，自引：0，他引：1
心理理论的研究是心理学中近年来研究的热点问题,心理理论是社会认知的重要组成部分。我国聋儿占残疾人总数的比例很大,探讨聋儿的心理发展与教育对于构建和谐社会具有十分重要的现实意义。目前对聋儿心理理论的研究主要集中在聋儿对错误信念的理解和其他心理状态的发展等方面。研究结果一致认为聋儿心理理论的发展落后于正常儿童,主要原因是语言交流障碍、早期家庭环境不良、学校教育不够重视等。对聋儿心理理论的培养应从注重早期诊断和语言训练、促进家庭中有效的语言交流、充分利用学校教育、扩大聋儿人际交往等方面入手。 相似文献

Even when they have good language skills, many children with hearing loss lag several years behind hearing children in the ability to grasp beliefs of others. The researchers sought to determine whether this lag results from difficulty with the verbal demands of tasks or from conceptual delays. The researchers related children's performance on a nonverbal theory of mind task to their scores on verbal aptitude tests. Twelve French children (average age about 10 years) with severe to profound hearing loss and 12 French hearing children (average about 7 years) were evaluated. The children with hearing loss showed persistent difficulty with theory of mind tasks, even a nonverbal task, presenting results similar to those of hearing 6-year-olds. Also, the children with hearing loss showed a correlation between language level (lexical and morphosyntactic) and understanding of false beliefs. No such correlation was found in the hearing children. 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

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

There are at least two languages (American Sign Language [ASL], English) and three modalities (sign, speech, print) in most deaf individuals' lives. Mixing of ASL and English in utterances of deaf adults has been described in various ways (pidgins, diglossia, language contact, bilingualism), but children's mixing usually is treated as the 'fault' of poor input language. Alternatively, how might language mixing serve their communication goals? This article describes code variations and adaptations to particular situations. Deaf children were seen to exhibit a wide variety of linguistic structures mixing ASL, English, Spanish, signing, and speaking. Formal lessons supported a recoding of English print as sign and speech, but the children who communicated English speech were the two who could hear speech. The children who communicated ASL were those who had deaf parents communicating ASL or who identified with deaf houseparents communicating ASL. Most language produced by the teacher and children in this study was mixed in code and mode. While some mixing was related to acquisition and proficiency, mixing, a strategy of many deaf individuals, uniquely adapts linguistic resources to communication needs. Investigating deaf children's language by comparing it to standard English or ASL overlooks the rich strategies of mixing that are central to their communication 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

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

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

The ability to comprehend and produce language stands as a defining characteristic of human cognition and enables the transfer of knowledge and culture within human society. A proper characterization of the human capacity for language is required for the development of interventions that may be used to assist those individuals who have failed to achieve, or who have lost competence in, language behaviors. For signed languages, models of competent language use are lacking. This lack of knowledge hampers the development of effective assessment measures for deaf children who may be experiencing learning problems beyond those confronting the normal deaf child. I discuss two research avenues that have begun to provide a window into the neural systems involved in sign language processing: studies of language disruptions in adult deaf signers who have suffered brain injury, and studies of functional brain imaging in normal deaf signers. This research provides a basis for the development of a comprehensive neurocognitive model of sign language processing. 相似文献
