We compared the reading development of 77 deaf and hard-of-hearing (DHH) Japanese children, aged 5–7 (40 females), with 139 of their hearing peers (74 females) in 2018. We assessed each group's phonological awareness (PA), grammar, vocabulary, and reading of hiragana (Japanese orthography children learn first). DHH children showed significant delays in grammar and vocabulary but only a slight delay in PA. Younger DHH children scored better than their hearing peers in reading. Although PA predicted reading for hearing children, reading predicted PA for DHH children. PA partially explained grammar skills for both groups. The results suggest educational intervention for reading acquisition should be based on not only general linguistic features but also each language's unique characteristics.  相似文献

Much research has found disrupted executive functioning (EF) in deaf and hard-of-hearing (DHH) children; while some theories emphasize the role of auditory deprivation, others posit delayed language experience as the primary cause. This study investigated the role of language and auditory experience in parent-reported EF for 123 preschool-aged children (Mage = 60.1 months, 53.7% female, 84.6% White). Comparisons between DHH and typically hearing children exposed to language from birth (spoken or signed) showed no significant differences in EF despite drastic differences in auditory input. Linear models demonstrated that earlier language exposure predicted better EF (β = .061–.341), while earlier auditory exposure did not. Few participants exhibited clinically significant executive dysfunction. Results support theories positing that language, not auditory experience, scaffolds EF development.  相似文献

Studies have suggested that language and executive function (EF) are strongly associated. Indeed, the two are difficult to separate, and it is particularly difficult to determine whether one skill is more dependent on the other. Deafness provides a unique opportunity to disentangle these skills because in this case, language difficulties have a sensory not cognitive basis. In this study, deaf (n = 108) and hearing (n = 125) children (age 8 years) were assessed on language and a wide range of nonverbal EF tasks. Deaf children performed significantly less well on EF tasks, even controlling for nonverbal intelligence and speed of processing. Language mediated EF skill, but the reverse pattern was not evident. Findings suggest that language is key to EF performance rather than vice versa.  相似文献

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.  相似文献

Longitudinal data were obtained from 157 children aged 3 years 3 months to 5 years 6 months at Time 1. At Time 2 these children had aged an average of 12 months. Theory of mind (ToM) and executive functioning (EF) were measured at both time points. Results suggest that Time 1 ToM scores predict Time 2 EF scores. Detailed examination of sibling influences suggests that benefits—in terms of advanced ToM development—accrue to children with siblings versus without, and to those with a larger number of child‐aged siblings. Any advance in either area (ToM or EF) is likely to benefit the other, and early sibling interaction appears to act as a catalyst.  相似文献

We examined whether family care following early-life deprivation buffered the association between stressful life events (SLEs) and executive functioning (EF) in adolescence. In early childhood, 136 institutionally reared children were randomly assigned to foster care or care-as-usual; 72 never-institutionalized children served as a comparison group. At age 16 years, adolescents (n = 143; 54% female; 67.1% Romanian) self-reported recent SLEs, completed a battery of memory and EF tasks, and completed a go/nogo task in which mediofrontal theta power (MFTP) was measured using electroencephalogram. More independent SLEs predicted lower EF and more dependent SLEs predicted lower MFTP, but only among adolescents with prolonged early deprivation. Findings provide preliminary evidence that family care following early deprivation may facilitate resilience against stress during adolescence on EF.  相似文献

The main point of our study was to examine the vocabulary knowledge of pupils in grades 3–6, and in particular the relative reading vocabulary disadvantage of hearing-impaired pupils. The achievements of 394 pupils with normal hearing and 106 pupils with a hearing impairment were examined on two vocabulary assessment tasks: a lexical decision task and a use decision task. The target words in both tasks represent the vocabulary children should have at the end of primary school. The results showed that most hearing pupils reached this norm, whereas most hearing-impaired pupils did not. In addition, results showed that hearing-impaired pupils not only knew fewer words, but that they also knew them less well. This lack of deeper knowledge remained even when matching hearing and hearing-impaired children on minimal word knowledge. Additionally, comparison of the two tasks demonstrated the efficacy of the lexical decision task as a measure of lexical semantic knowledge.  相似文献

This study of 195 (108 boys) children seen twice during infancy (Time 1: 4.12 months; Time 2: 14.42 months) aimed to investigate the associations between and infant predictors of executive function (EF) at 14 months. Infants showed high levels of compliance with the EF tasks at 14 months. There was little evidence of cohesion among EF tasks but simple response inhibition was related to performance on two other EF tasks. Infant attention (but not parent-rated temperament) at 4 months predicted performance on two of the four EF tasks at 14 months. Results suggest that EF skills build on simpler component skills such as attention and response inhibition.  相似文献

Frequent somatic complaints are not only a problem in themselves but also related to other difficulties. So far, no conclusive findings have been reported about the prevalence of and factors underlying these complaints in children and adolescents who are deaf or hard of hearing (DHH). Such information would be valuable for prevention and intervention. Therefore, the aim of this study was to examine the prevalence of somatic complaints and their relation with emotional functioning in DHH youngsters, as compared with hearing youngsters. This was established by assessing how somatic complaints, mood states, and sense of coherence were experienced by 186 Dutch participants (mean age = 11;07 years). DHH and hearing groups were compared using multivariate analysis of variance and structural equation modeling. The results showed that somatic complaints were reported equally often for both groups, but that the pathways leading to these complaints were partly different. Only in DHH participants were feelings of fear associated with more somatic complaints. The results suggest that DHH children and adolescents would benefit from support in the regulation of fear and its causes. Other aspects affecting adjustment outcomes of DHH youngsters were education type and communication mode.  相似文献

The purpose of the present study was to examine the prevalence of child maltreatment and lifetime exposure to other traumatic events in a sample of deaf and hard of hearing (DHH; n = 147) and matched hearing (H; n = 317) college students. Participants completed measures of child maltreatment (CM), adult victimization and trauma exposure, and current symptoms of posttraumatic stress disorder (PTSD). Overall, DHH participants reported significantly more instances of CM compared to H participants, with 76% of DHH reporting some type of childhood abuse or neglect. Additionally, DHH participants reported experiencing a higher number of different types of CM, and also reported increased incidents of lifetime trauma exposure and elevated PTSD symptoms. Severity of deafness increased the risk of maltreatment, with deaf participants reporting more instances of CM than hard of hearing participants, and hard of hearing participants reporting more instances of CM than H participants. Among DHH participants, having a deaf sibling was associated with reduced risk for victimization, and identification with the Deaf community was associated with fewer current symptoms of PTSD. A regression model including measures of childhood physical and sexual abuse significantly predicted adult re-victimization and accounted for 27% of the variance among DHH participants. DHH participants report significantly higher rates of CM, lifetime trauma, and PTSD symptoms compared to H participants. Severity of deafness appears to increase the risk of being victimized. Being part of the Deaf community and having access to others who are deaf appear to be important protective factors for psychological well-being among DHH individuals.  相似文献

There is substantial variance in the age at which children construct and deploy their first explicit theory of biology. This study tests the hypothesis that this variance is due, at least in part, to individual differences in their executive function (EF) abilities. A group of 79 boys and girls aged 5–7 years (with a mean age of 6½ years) were presented with two test batteries: (a) a biology battery that probed their understanding of life, death, and body functions and (b) an EF battery that tested working memory, inhibition, and set‐shifting skills. Individuals' EF scores significantly predict their biology scores, even after controlling for age and verbal IQ.  相似文献

This study aimed to test a four-wave sequential mediation model linking mother–child attachment to children's school readiness through child executive functioning (EF) and prosociality in toddlerhood and the preschool years. Mother–child attachment security was assessed when children (N = 255) were aged 15 months and 2 years, child EF at age 2, prosocial behavior at age 4, and finally cognitive school readiness in kindergarten (age 6). The results revealed three indirect pathways linking attachment to school readiness: one through EF only, one through prosocial behavior only, and a last pathway involving both EF and prosocial behavior serially. These findings suggest that secure attachment may equip children with both cognitive and social skills that are instrumental to their preparedness for school.  相似文献

This paper describes findings of a longitudinal study that was carried out to examine relationships among different aspects of young children's cognitive development, namely, theory of mind, metacognitive vocabulary, and metamemory, which seem theoretically connected but so far have not been studied simultaneously. In total, 174 children were included in the present analyses who were about 4;6 years of age at the first measurement point. Children were tested at four time points, separated by a testing interval of approximately half a year. At the first time of testing, children completed a set of theory of mind tasks. At each of the following measurement points, measures of metacognitive vocabulary and general vocabulary as well as metamemory were given. Overall, the findings show that theory of mind performance assessed at the age of 4;6 predicts metacognitive knowledge assessed about one and a half years later. Furthermore, they point to a reciprocal relationship between metacognitive vocabulary and metamemory in that comprehension of metacognitive vocabulary predicted later metamemory and, conversely, metamemory significantly predicted later comprehension of metacognitive verbs. This research was supported by a grant from the German Research Foundation (SCHN 315 /20–7) to the German Research Group on Cognitive Development.  相似文献

Longitudinal associations between signaled night awakening and executive functioning (EF) at 8 and 24 months in children with (≥ 3 awakenings, n = 77) and without parent-rated fragmented sleep (≤ 1 awakening, n = 69) were studied. EF was assessed with the Switch task at 8 and 24 months. At 24 months, behavioral tasks and parental ratings of EF (Behavior Rating Inventory of Executive Function–Preschool version) were also used. In the Switch task, children with fragmented sleep were less able to learn stimulus sequences and inhibit previously learned responses than children without fragmented sleep. The groups differed only marginally in parental ratings of EF, and no differences were found in behavioral EF tasks. These results suggest that eye movement-based measures may reveal associations between sleep and EF already in infancy and toddlerhood.  相似文献

This study investigated the phonological processing skills of 29 children with prelingual, profound hearing loss with 4 years of cochlear implant experience. Results were group matched with regard to word-reading ability and mother's educational level with the performance of 29 hearing children. Results revealed that it is possible to obtain a valid measure of phonological processing (PP) skills in children using CIs. They could complete rhyming tasks and were able to complete sound-based tasks using standard test materials provided by a commercial test distributor. The CI children completed tasks measuring PP, but there were performance differences between the CI users and the hearing children. The process of learning phonological awareness (PA) for the children with CIs was characterized by a longer, more protracted learning phase than their counterparts with hearing. Tests of phonological memory skills indicated that when the tasks were controlled for presentation method and response modality, there were no differences between the performance of children with CIs and their counterparts with hearing. Tests of rapid naming revealed that there were no differences between rapid letter and number naming between the two groups. Results yielded a possible PP test battery for children with CI experience.  相似文献

This study examined the concurrent relations of English (EL) and heritage language (HL) proficiency to executive functions (EF) among low-income dual language learners (DLLs) from immigrant families. In a sample of 90 children (age = 38–70 months) from Chinese-speaking Chinese American and Spanish-speaking Mexican American families recruited from Head Start preschools, children’s EL and HL proficiency was assessed using receptive and expressive vocabulary tests, and EF was assessed using behavioral tasks measuring response inhibition and attention shifting. Multiple regressions were conducted to test the unique and interactive relations of EL and HL vocabulary to EF, controlling for family socioeconomic status and other demographic characteristics. Higher EL and higher HL vocabulary were uniquely associated with higher attention shifting. By contrast, neither EL nor HL vocabulary was uniquely associated with response inhibition. Interaction effects of EL × HL in relation to EF were also found. The results provided some evidence for the dual benefits of EL and HL proficiency on EF (especially attention shifting) among DLLs from low-income, immigrant families.  相似文献

ObjectiveThough children exposed to familial violence are reported to have difficulties with a range of emotional and behavioral problems (e.g., lower school achievement) that implicate executive function (EF) deficits, relatively little research has specifically examined EF as a function of trauma exposure in children.MethodsBased on parent report of children's exposure to potentially traumatic events, children (N = 110; AgeMean = 10.39) from an ethnically diverse community sample were compared across three trauma-exposure groups: familial trauma, non-familial trauma, and no trauma. Children completed a battery of tests to assess working memory, behavioral inhibition, processing speed, auditory attention, and interference control.ResultsFamilial trauma (relative to non-familial and no trauma exposure) was associated with poorer performance on an EF composite (composed of working memory, inhibition, auditory attention, and processing speed tasks); the effect size was medium. Both trauma-exposure status and dissociation symptoms explained unique variance in EF performance after controlling for anxiety symptoms, socio-economic status, and potential traumatic brain injury. While IQ and EF performance were related, SES predicted unique variance in IQ (and not EF) scores, while familial-trauma exposure did not.ConclusionsThe contribution of trauma exposure to basic executive functioning held after taking into account symptoms (anxiety and dissociation), socio-economic status, and possible traumatic brain injury exposure. EF problems may provide one route via which maltreated children become at risk for peer, academic, and behavior problems relative to their peers.Practice implicationsEF problems may provide one route via which maltreated children become at risk for peer, academic, psychological, and behavior problems relative to their peers. Recently, intervention strategies have emerged in the anxiety and mood disorder treatment literatures that appear to effectively target EFs. As future research continues to specify the relationship between child trauma exposure and EF performance, these innovative treatments may have important practice implications for addressing EF deficits.  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

The association between executive function (EF) and theory of mind (ToM) has been hotly debated for 20 years. Competing accounts focus on: task demands, conceptual overlap, or functional ties. Findings from this meta‐analytic review of 102 studies (representing 9,994 participants aged 3–6 years) indicate that the moderate association between EF and one key aspect of ToM, false belief understanding (FBU) is: (a) similar for children from different cultures, (b) largely consistent across distinct EF tasks, but varies across different types of false belief task, and (c) is asymmetric in that early individual differences in EF predict later variation in FBU but not vice versa. These findings support a hybrid emergence‐expression account and highlight new directions for research.  相似文献

The present study explored direct and interactive effects between behavioral self-regulation (SR) and two measures of executive function (EF, inhibitory control and working memory), with a fine motor measure tapping visuomotor skills (VMS) in a sample of 127 prekindergarten and kindergarten children. It also examined the relative contribution of behavioral SR, EF, and VMS skills for concurrent academic achievement. Results indicated that a measure of working memory (WJ-Working Memory) and a measure of behavioral SR (Head–Toes–Knees–Shoulders task; HTKS) were directly related to VMS. Differential relations were also examined for prekindergarten and kindergarten children. Results revealed a significant interaction between age and inhibitory control (Day–Night), and an interaction at a trend level between age and working memory suggesting both tasks are more related to VMS skills for younger children. Results also indicated that behavioral SR, EF, and VMS skills were differentially related to the three achievement outcomes. Both behavioral SR and VMS were significantly related to math, behavioral SR, EF, and VMS were significantly related to emergent literacy, and behavioral SR and EF were related to vocabulary scores. Results point to significant relations between behavioral SR and EF with VMS, and how each is related to early academic achievement in preschool and kindergarten.  相似文献
