Theory of mind and language in children with cochlear implants

Thirty children with cochlear implants (CI children), age range 3-12 years, and 30 children with normal hearing (NH children), age range 4-6 years, were tested on theory of mind and language measures. The CI children showed little to no delay on either theory of mind, relative to the NH children, or spoken language, relative to hearing norms. The CI children showed a slightly atypical sequence of acquisition of theory of mind concepts. The CI children's theory of mind performance was associated with general syntactic proficiency more than measures of complement syntax, and with time since implantation more than age at implantation. Results suggest that cochlear implantation can benefit spoken language ability, which may then benefit theory of mind, perhaps by increasing access to mental state language.     

听障儿童与正常儿童的自我意识对比研究

采用儿童自我意识量表对119名听障儿童与157名正常儿童进行了测试,结果发现:听障儿童在合群上存在明显的性别差异,正常儿童在行为、躯体外貌与属性、合群上存在显著的性别差异;听障儿童与正常儿童相比,自我意识偏低水平的比例明显高于正常儿童,而偏高水平的比例则明显低于正常儿童;听障儿童对自身的行为、焦虑、合群、幸福与满足等方面的意识明显地低于正常儿童,而对智力与学校情况、躯体外貌与属性的意识,则明显地高于正常儿童。     

Social competence, sense of loneliness, and speech intelligibility of young children with hearing loss in individual inclusion and group inclusion

The study focused on social competence (SC) and perceived sense of loneliness of preschool children with hearing loss (HL) in group inclusion (GI, a small group of children with HL is integrated in a standard classroom) and individual inclusion (II, each child with HL is individually integrated into a standard classroom). The relations between these factors and the child's speech intelligibility were performed. Sixty-four children aged 4-7 years participated: 22 from an II and 42 from a GI. SC, perceived sense of loneliness, and speech intelligibility were evaluated through the use of questionnaires completed by the preschool teachers. The results showed that the SC of children in II was higher than the SC of the children in GI, while interacting with normal hearing (NH) children. In GI, the children's SC with other children with HL was higher compared with their SC with NH children. In both groups, there were relationships between speech intelligibility and SC with NH children. In addition, in the II setting, there were relationships between the speech intelligibility and the perceived sense of loneliness. These relationships were not found in the GI setting. The findings support the need for coenrollment of preschool children with HL and emphasize the crucial impact of speech intelligibility of children with HL on the success of their social enrollment with NH children, already at a young age.     

Peer relationships of children with cochlear implants

Previous research on children with cochlear implants has focused mostly on their speech perception and production. With the growing numbers of children who use the implant, it is important to assess other aspects of these children's functioning. This article offers a qualitative and quantitative analysis of interviews with parents who described their children's communication skills and peer relationships before they had the implant and afterward. Results show that the implant has the potential to improve deaf children's relationships with hearing peers. Nonetheless, children with implants still face communication obstacles, which impede their social relationships with hearing peers. Results are discussed in light of the different points of view of various "stake holders" regarding cochlear implants in children.     

Deaf children's use of phonological coding: evidence from reading, spelling, and working memory

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.

Conversations between deaf children and their hearing mothers: pragmatic and dialogic characteristics

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.     

Contributions of the emergent literacy environment to literacy outcomes for young children who are deaf

Specific characteristics of early literacy environments support hearing children's emergent literacy. The researchers investigated these characteristics' role in emergent literacy in young deaf and hard of hearing (DHH) children, using the Early Language and Literacy Classroom Observation (ELLCO; M. W. Smith, Dickinson, Sangeorge, & Anastasopoulos, 2002). Eighteen self-contained classrooms of preschool, kindergarten, and first-grade DHH children (N = 40) were studied. Hierarchical linear analysis was used to examine study participants' classroom environment and growth in emergent literacy skills. Correlations suggested that classroom environment was more closely related to vocabulary and phonological awareness in DHH children than in typically hearing children. Major differences among classrooms were also indicated. However, growth in children's skills did not correlate strongly with attributes captured by the ELLCO. This suggests that classrooms promoting emergent literacy skills acquisition in DHH children may differ from classrooms of typically developing hearing children.     

The experience of story reading: deaf children and hearing mothers' interactions at story time

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.     

Preschool Children's Understanding of Disability: Experiences Leading to the Elaboration of the Concept of Hearing Loss

The impact of participation in a classroom with a peer with a severe hearing loss on preschool children's understanding of hearing and hearing loss was investigated. Subjects included children with and without a peer who had a hearing impairment. All children referred to their own experiences to explain hearing loss. Children who had a hearing-impaired classmate demonstrated a more complete understanding of sign language and the consequences of hearing loss than children without this experience. The implications of these results for children who are enrolled in inclusive preschool programs is discussed.     

The performance of young deaf children in spatial and temporal number tasks

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.     

Changes in early adolescents' sense of responsibility to their parents in the United States and China: implications for academic functioning

This research examined American and Chinese children's sense of responsibility to their parents during early adolescence, with a focus on its implications for children's academic functioning. Four times over the seventh and eighth grades, 825 children (mean age = 12.73 years) in the United States and China reported on their sense of responsibility to their parents. Information on children's academic functioning was also collected from children as well as school records. Although children's sense of responsibility to their parents declined over the seventh and eighth grades in the United States, this was not the case in China. In both countries, children's sense of responsibility was predictive of enhanced academic functioning among children over time.     

Relations between maternal input and theory of mind understanding in deaf children

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.     

Parenting stress and social support in hearing mothers of deaf and hearing children: a longitudinal study

This longitudinal study investigated the impact of child deafness on mothers' stress, size of social networks, and satisfaction with social support. Twenty-three hearing mothers of deaf children and 23 hearing mothers of hearing children completed a series of self-report questionnaires when their children were 22 months, 3, and 4 years old. When children were 22 months, more mothers of deaf children reported pessimism about their children's achieving self-sufficiency and concerns about their children's communication abilities than did mothers of hearing children. When their children were 3 and 4 years old, mothers of deaf and hearing children did not differ in their reports of general parenting stress, as measured by the Parenting Stress Index (PSI). Likewise, mothers' ratings of satisfaction with social support were not affected by child deafness, nor did they change developmentally. Mothers of deaf and hearing children did differ in the types of support networks utilized. Mothers of deaf 22-month-olds reported significantly larger professional support networks, while mothers of hearing children reported significantly larger general support networks across all child ages. Mothers' feelings of stress and satisfaction with social support were very stable across the 2 years examined. The results suggest that most mothers of deaf children do not feel a high level of general parenting stress or dissatisfaction with their lives and support networks. However, mothers of deaf children are likely to feel stress in areas specific to deafness. In addition, because parenting stress was highly stable, special efforts should be made to intervene when mothers of deaf children are expressing high levels of stress.     

Positive justice reasoning in deaf and hearing children before and after exposure to cognitive conflict

The development of positive justice reasoning in profoundly deaf, signing Australian 7- to 12-year-olds and hearing children was compared. Reactions to cognitive conflict were also assessed. The performance of those deaf children whose signed English skills were adequate to give detailed justifications for reward allocation was examined separately. The deaf children were delayed relative to hearing children in number and liquid conservation, but equally mature in justice reasoning. Spontaneous conflicts with signing peers over sharing possessions conceivably could be responsible for the fluently signing deaf children's development of positive justice reasoning on pace with their normally-hearing counterparts. Experimentally-induced conflict resulted in progress for the hearing but not the deaf children. Results are discussed in relation to factors that promote deaf children's tolerance for ambiguity (Brice, 1985) and impede their resolution of cognitive conflict (Liben, 1978).     

Joint attention strategies used by a preschool educator who is deaf

This exploratory study examined the attention-gaining and attention-regaining strategies used by a preschool educator who is Deaf during child-directed play. Four children (2 with typical hearing and 2 with severe-to-profound hearing loss) were videotaped interacting with the educator in two different play contexts. The educator used four different strategies to gain and to regain the children's attention: visual, visual using an American Sign Language (ASL) sign, tactile/vibratory, and observing/waiting. Overall, tactile and visual strategies were used with the same frequency and occurred more often than either waiting or using an ASL sign to establish joint attention. With the exception of waiting, all strategies were equally successful at gaining or regaining the children's attention. The knowledge and experience of educators with hearing loss potentially provide important insights into enhancing the effectiveness of the communicative environment for preschool children with hearing loss. The implications of this line of inquiry include training for educators on the effective use of strategies to establish joint attention with preschool children with hearing loss.

Family supports and resources for parents of children who are deaf or hard of hearing

The study examined family supports after identification of children's hearing loss. On a questionnaire, 456 respondents rated the importance of different aspects of family support, the quality of supports they experienced, and their preferences about informational resources. They verified the importance of informational resources, social-emotional support, and educational advocacy. Families expressed a preference for discussion with other parents of children with hearing loss over discussion with parents of children without hearing loss. The quality of support was rated higher by parents of children with cochlear implants than by parents of children with hearing aids. Top-ranked sources of support included individual professionals and service providers, other parents of children with hearing loss, family support organizations, and grandparents and extended-family members. Open-ended written responses indicated that parents desired additional opportunities to connect with mentors, role models, and other parents.     

The impact of verbal capacity on theory of mind in deaf and hard of hearing children

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.     

Do you see what I see? School perspectives of deaf children,hearing children and their parents☆

Perspectives on academic and social aspects of children’s school experiences were obtained from deaf and hearing children and their (deaf or hearing) parents. Possible differences between (1) the views of children and their parents and (2) those of hearing children and their parents compared to deaf children and their parents were of particular interest. Overall, parents gave their children higher school friendship ratings than the children gave themselves, and hearing children and their parents were more positive about children’s friendships than were deaf children and their parents. Both children and parents also saw deaf children as less successful in reading than hearing children. However, deaf children having deaf parents, attending a school for the deaf and using sign language at home all were associated with more positive perceptions of social success. Use of cochlear implants was not associated with perceptions of greater academic or social success. These and related findings are discussed in the context of parent and child perspectives on social and academic functioning and particular challenges confronted by deaf children in regular school settings.
