We compared 20 prelingually profoundly deaf adolescents (age: 11-16 years) and 20 matched, hearing adolescents on a picture-sequencing task and on a social judgment test. In addition, we also tested 14 younger deaf children (age: 6-10 years) and compared their data with those from 20 hearing peers as well as those from the older deaf participants on the picture-sequencing task. The results from this study did not provide evidence for the hypothesis that deaf adolescents possess significantly poorer knowledge about social reasoning than age-matched hearing peers, but it did present further additional support for Peterson and Siegal's (1995) conversational hypothesis: a proposal that a deprivation in conversations about mental states leads to an impairment in the development of an awareness of mental states in the younger deaf children.  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

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

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

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

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

Meta-analysis of theory-of-mind development: the truth about false belief   总被引:58,自引:0,他引:58  
Research on theory of mind increasingly encompasses apparently contradictory findings. In particular, in initial studies, older preschoolers consistently passed false-belief tasks-a so-called "definitive" test of mental-state understanding-whereas younger children systematically erred. More recent studies, however, have found evidence of false-belief understanding in 3-year-olds or have demonstrated conditions that improve children's performance. A meta-analysis was conducted (N = 178 separate studies) to address the empirical inconsistencies and theoretical controversies. When organized into a systematic set of factors that vary across studies, false-belief results cluster systematically with the exception of only a few outliers. A combined model that included age, country of origin, and four task factors (e.g., whether the task objects were transformed in order to deceive the protagonist or not) yielded a multiple R of .74 and an R2 of .55; thus, the model accounts for 55% of the variance in false-belief performance. Moreover, false-belief performance showed a consistent developmental pattern, even across various countries and various task manipulations: preschoolers went from below-chance performance to above-chance performance. The findings are inconsistent with early competence proposals that claim that developmental changes are due to tasks artifacts, and thus disappear in simpler, revised false-belief tasks; and are, instead, consistent with theoretical accounts that propose that understanding of belief, and, relatedly, understanding of mind, exhibit genuine conceptual change in the preschool years.  相似文献

Theory-of-mind concepts in children with deafness, autism, and normal development (N = 154) were examined in three experiments using a set of standard inferential false-belief tasks and matched sets of tasks involving false drawings. Results of all three experiments replicated previously published findings by showing that primary school children with deafness or autism, aged 6 to 13 years, scored significantly lower than normal-developing 4-year-old preschoolers on standard misleading-container and unseen-change tests of false-belief understanding. Furthermore, deaf and autistic children generally scored higher on drawing-based tests than on corresponding standard tests and, on the most challenging of the false-drawing tests in Experiment 2, they significantly outperformed the normal-developing preschoolers by clearly understanding their own false intentions and another person's false beliefs about an actively misleading drawing. In Experiment 3, preschoolers outperformed older deaf and autistic children on standard tasks, but did less well on a task that required the drawing of a false belief. Methodological factors could not fully explain the findings, but early social and conversational experiences in the family were deemed likely contributors.  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

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

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

This article examines the role of mode of acquisition (MoA) of word meanings in reading comprehension: children acquire word meanings using perceptual information (e.g., hearing, seeing, or smelling the referent) and/or linguistic information (e.g., verbal explanations). A total of 72 deaf and 99 hearing children between 7 and 15 years of age performed a self-paced reading task. Comprehension scores increased with age in both groups, but reading speed increased over age only for the hearing participants. For both groups, reading times on linguistically acquired words were longer than on perceptually acquired words. Although deaf children scored lower than hearing children in both conditions, comprehension scores for both groups were lower on linguistic items than on perceptual items. Thus, MoA influences reading comprehension, but the deaf show difficulty on both the perceptual and the linguistic items.  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

Theory of mind and self-control: more than a common problem of inhibition   总被引:14,自引:0,他引:14  
Perner J  Lang B  Kloo D 《Child development》2002,73(3):752-767
This study tested the theory that advances on theory-of-mind tasks and on executive function tasks show a strong correlation because the typically used theory-of-mind tasks pose the same executive demands. In Experiment 1 with fifty-six 3- to 6-year-old children, performance on the dimensional change card-sorting task as an executive function task was correlated with performance on the usual false-belief prediction task, r = .65, and the false-belief explanation task, r = .65, as measures of theory-of-mind development. Because the explanation version of the false-belief test is supposed to be free of the alleged executive demands inherent in the prediction version, the equally strong correlation with the executive function task suggests that this correlation cannot be due to common executive demands. In Experiment 2, the basic finding of Experiment 1 was replicated on another sample of 73 children, ages 3 to 5.5 years. The need for new theories to explain the developmental link between theory of mind and executive function development is discussed, and some existing candidates are evaluated.  相似文献

The performance of deaf children with cochlear implants was assessed using measures standardized on hearing children. To investigate nonverbal cognitive and sensorimotor processes associated with postimplant variability, five selected sensorimotor and visuospatial subtests from A Developmental Neuropsychological Assessment (NEPSY) were compared with standardized vocabulary, reading, and digit span measures. Participants were 26 deaf children, ages 6-14 years, who received a cochlear implant between ages 1 and 6 years; duration of implant use ranged from 3 to 11 years. Results indicated significant correlations between standard scores on the Design Copying subtest of the NEPSY and standard scores on vocabulary comprehension, reading, and digit span measures. The results contribute to our understanding of the benefits of cochlear implantation and cognitive processes that may support postimplant language and academic functioning.  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

Previous studies of preverbal development have highlighted the recurrent difficulties experienced by deaf children in acquiring knowledge of the social rules and social skills pertaining to discourse. We expected cochlear implants in children with bilateral profound deafness to improve their use of verbal language, so that their communication skill profile resembled that of younger, hearing children. Using conversation samples taken from videos recorded every 6 months over a 2-year period, we monitored the development of communication skills in a group of 18 prelingually profoundly deaf children (mean implantation age, 3 years and 5 months). Results corroborated our hypothesis that the overall communication performances of children with cochlear implants improve, both quantitatively and qualitatively, as early as the first year post-implantation.  相似文献

Language skills were investigated in a multicultural sample of 13 prelingually deaf children (11 profoundly deaf from birth) who received cochlear implants between 14 and 38 months of age; average duration of implant use was 49 months. Individual postimplant language skills ranged from extremely delayed to age appropriate. On average, skills varied across domains: on vocabulary, several children functioned in the average range compared with hearing peers, but all were below that range on a test emphasizing syntax (CELF-P). Children with preimplant hearing experience had the highest scores on all language measures. Excluding these children, age of implantation (range 14 to 27 months) associated inversely and significantly with CELF-P scores, even when nonverbal IQ was controlled. Qualitative analyses indicated higher child language achievement associated with parents' reports of lengthy, in-depth processes to decide about cochlear implantation. Such reports may indicate high levels of ongoing parent involvement with child and programming.  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
