During a visual rhyming task, deaf participants traditionally perform more poorly than hearing participants in making rhyme judgements for written words in which the rhyme and the spelling pattern are incongruent (e.g. hair/bear). It has been suggested that deaf participants’ low accuracy results from their tendency to rely on orthographic similarity. To test this interpretation more directly, we compared profoundly and prelingually deaf, orally educated participants and hearing participants’ accuracy during a visual rhyming judgement task in which the two words of a pair share the orthographic rime, in order to discourage usage of a purely orthographic strategy. Accuracy was lower in deaf than in hearing participants. The gradient of difficulty between items, together with the finding of a significant correlation between accuracy and the consistency of the grapheme to rhyme, suggest that difference in accuracy between groups might be explained by an over regularization in deaf people, which is probably linked to less diversified phonological representations.  相似文献

We assessed the reading and reading-related skills (phonemic awareness and phonological short-term memory) of deaf children fitted with cochlear implants (CI), either exposed to cued speech early (before 2 years old) (CS+) or never (CS-). Their performance was compared to that of 2 hearing control groups, 1 matched for reading level (RL), and 1 matched for chronological age (CA). Phonemic awareness and phonological short-term memory were assessed respectively through a phonemic similarity judgment task and through a word span task measuring phonological similarity effects. To assess the use of sublexical and lexical reading procedures, children read pseudowords and irregular words aloud. Results showed that cued speech improved performance on both the phonemic awareness and the reading tasks but not on the phonological short-term memory task. In phonemic awareness and reading, CS+ children obtained accuracy and rapidity scores similar to CA controls, whereas CS- children obtained lower scores than hearing controls. Nevertheless, in phonological short-term memory task, the phonological similarity effect of both CI groups was similar. Overall, these results support the use of cued speech to improve phonemic awareness and reading skills in CI children.  相似文献

Most studies on the Stroop effect (unintentional automatic word processing) have been restricted to English speakers using vocal responses. Little is known about this effect with deaf signers. The study compared Stroop task responses among four different samples: deaf participants from a Japanese-language environment and from an English-language environment; and hearing individuals from Japan and from Australia. Color words were prepared in both English and Japanese and were presented in three conditions: congruent (e.g., the word red printed in red), incongruent (e.g., red printed in blue), and neutral. The magnitude of the effect was greater with the deaf participants than with the hearing participants. The deaf individuals experienced more interference in English than in Japanese.  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

The current study examined the nature of deaf readers’ phonological processing during online word recognition, and how this compares to similar effects in hearing individuals. Unlike many previous studies on phonological activation, we examined whether deaf readers activated phonological representations for words as opposed to pseudohomophones. Both hearing and deaf adults performed lexical decisions on homophones and control words in the context of either pseudoword foils (e.g., CLANE) or pseudohomophone foils (e.g., BRANE). As expected, hearing readers responded more slowly to homophones than to control words in both non-word contexts, reflecting phonological activation during reading. In contrast, deaf readers responded more slowly to homophones than to control words in the pseudohomophone foil context, but not in the pseudoword foil context. This finding suggests that deaf readers are able to activate phonological representations; however the nature of these representations appears to be more coarse-grained in deaf readers.  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

This paper studies the linguistic input attended by a deaf child exposed to cued speech (CS) in the final part of her prelinguistic period (18-24 months). Subjects are the child, her mother, and her therapist. Analyses have provided data about the quantity of input directed to the child (oral input, more than 1,000 words per half-an-hour session; cued ratio, more than 60% of oral input; and attended ratio, more than 55% of oral input), its linguistic quality (lexical variety, grammatical complexity, etc.), and other properties of interaction (child attention and use of spontaneous gestures). Results show that both adults provided a rich linguistic input to the child and that the child attended most of the input that the adults cued. These results might explain the positive linguistic development of children exposed early to CS.  相似文献

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 aim of the study is to describe the performance of deaf and hearing people while speechreading Spanish, a language with transparent orthography, and to relate this skill to reading efficiency. Three groups of 27 participants each were recruited: a group of deaf participants, a chronological age‐matched hearing group and a reading age‐matched hearing group. All three were tested on vocabulary, phonological awareness, reading speed, speechreading and, only in the group of deaf people, speech intelligibility. The results indicate that deaf people are better speechreaders than younger hearing people, but they are no better than their age‐matched peers, and that speechreading is related to reading only in deaf people.  相似文献

The present study concerns ethnic, age, and gender playmate preferences of deaf and hearing preschoolers who were observed during outdoor free play at their respective schools over a 7-month period. Hispanic, black, and white children were included. It was hypothesized that peer preferences would be less apparent among deaf children than among hearing children if these preferences were based on (a) language differences between ethnic groups (e.g., Spanish-English differences), age groups (e.g., verbal fluency differences), or gender groups; or (b) cultural values communicated by speech. Both deaf and hearing children preferred to play with children of the same ethnicity, gender, and age as themselves. In addition, play among children of the same ethnicity, gender, and age was qualitatively different from play among children of different ethnicity, gender, and age. The only effect of deafness was to decrease the amount of gender segregation that occurred. The results suggest that the development of ethnic, gender, and age playmate preferences is not dependent on intergroup language differences or spoken cultural messages. Several nonlinguistic factors that might contribute to early peer preferences are discussed.  相似文献

This research examined the use of visual-spatial representation by deaf and hearing students while solving mathematical problems. The connection between spatial skills and success in mathematics performance has long been established in the literature. This study examined the distinction between visual-spatial "schematic" representations that encode the spatial relations described in a problem versus visual-spatial "pictorial" representations that encode only the visual appearance of the objects described in a problem. A total of 305 hearing (n = 156) and deaf (n = 149) participants from middle school, high school, and college participated in this study. At all educational levels, the hearing students performed significantly better in solving the mathematical problems compared to their deaf peers. Although the deaf baccalaureate students exhibited the highest performance of all the deaf participants, they only performed as well as the hearing middle school students who were the lowest scoring hearing group. Deaf students remained flat in their performance on the mathematical problem-solving task from middle school through the college associate degree level. The analysis of the students' problem representations showed that the hearing participants utilized visual-spatial schematic representation to a greater extent than did the deaf participants. However, the use of visual-spatial schematic representations was a stronger positive predictor of mathematical problem-solving performance for the deaf students. When deaf students' problem representation focused simply on the visual-spatial pictorial or iconic aspects of the mathematical problems, there was a negative predictive relationship with their problem-solving performance. On two measures of visual-spatial abilities, the hearing students in high school and college performed significantly better than their deaf peers.  相似文献

This study extends the findings of Gaustad, Kelly, Payne, and Lylak (2002), which showed that deaf college students and hearing middle school students appeared to have approximately the same morphological knowledge and word segmentation skills. Because the average grade level reading abilities for the two groups of students were also similar, those research findings suggested that deaf students' morphological development was progressing as might be expected relative to reading level. This study further examined the specific relationship between morphologically based word identification skills and reading achievement levels, as well as differences in the error patterns of deaf and hearing readers. Comparison of performance between pairs of deaf college students and hearing middle school students matched for reading achievement level shows significant superiority of younger hearing participants for skills relating especially to the meaning of derivational morphemes and roots, and the segmentation of words containing multiple types of morphemes. Group subtest comparisons and item analysis comparisons of specific morpheme knowledge and word segmentation show clear differences in the morphographic skills of hearing middle school readers over deaf college students, even though they were matched and appear to read at the same grade levels, as measured by standardized tests.  相似文献

A comparison was made between prelingually deaf and hearing children matched on reading age (between 7:0 and 7:11 years) in order to examine possible differences in reading performance. The deaf children all had a severe or profound hearing loss and were receiving special education in either a school or a unit for the deaf. The experimental tasks used a lexical decision task involving the reading of single words. The employment of phonology in reading was investigated by comparing reading performance on regular and irregular words and by comparing reading of homophonic versus non–homophonic nonwords. Both tasks revealed that hearing participants were much more affected by regularity and homophony, suggesting a much greater reliance on assembled phonological recoding. These results are discussed in terms of deaf readers relying on lexical access for reading print.  相似文献

The emerging reading and spelling abilities of 24 deaf and 23 hearing beginning readers were followed over 2 years. The deaf children varied in their language backgrounds and preferred mode of communication. All children were given a range of literacy, cognitive and language-based tasks every 12 months. Deaf and hearing children made similar progress in literacy in the beginning stages of reading development and then their trajectories began to diverge. The longitudinal correlates of beginning reading in the deaf children were earlier vocabulary, letter-sound knowledge, and speechreading. Earlier phonological awareness was not a longitudinal correlate of reading ability once earlier reading levels were controlled. Only letter name knowledge was longitudinally related to spelling ability. Speechreading was also a strong longitudinal correlate of reading and spelling in the hearing children. The findings suggested that deaf and hearing children utilize slightly different reading strategies over the first 2 years of schooling.  相似文献

This article begins with the rationale for a detailed assessment of prelinguistic behaviors in young deaf children. I used a Hebrew adaptation of the parent questionnaire developed by Camaioni, Caselli, Volterra, and Luchenti (1992) in Italy to collect data on a relatively large heterogeneous Israeli sample of deaf participants: 43 deaf children of hearing parents (19 girls and 24 boys) ranging in age from 8 to 49 months. Results indicated that prelinguistic behaviors in deaf infants resemble only to some extent the theoretical model of prelinguistic communication in hearing infants. Unique interrelationships emerged among pointing and early noncommunicative behaviors, yet no correlation emerged between the use of referential gestures and early words or signs. We analyzed findings with respect to the comparison of prelinguistic behavioral characteristics in hearing and deaf children and the collaboration with parents in assessing the prelinguistic behaviors of their own deaf children.  相似文献

We evaluated language development in deaf Italian preschoolers with hearing parents, taking into account the duration of formal language experience (i.e., the time elapsed since wearing a hearing aid and beginning language education) and different methods of language education. Twenty deaf children were matched with 20 hearing children for age and with another 20 hearing children for duration of experience. Deaf children showed a significant delay in both vocabulary and grammar when compared to same-age hearing children yet a similar development compared to hearing children matched for duration of formal language experience. The delay in linguistic development could be attributable to shorter formal language experience and not to deafness itself. Deaf children exposed to spoken language accompanied by signs tended to understand and produce more words than children exposed only to spoken language. We suggest that deaf children be evaluated based on their linguistic experience and cognitive and communicative potential.  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

Adults of varying reading comprehension skill learned a set of previously unknown rare English words (e.g., gloaming) in three different learning conditions in which the type of word knowledge was manipulated. The words were presented in one of three conditions: (1) orthography-to-meaning (no phonology); (2) orthography-to-phonology (no meaning); and (3) phonology-to-meaning (no orthography). Following learning, participants made meaning judgments on the learned words, familiar known words, and unpresented (unlearned) rare words while their ERPs were recorded. The behavioral results showed no significant effects of comprehension skill on meaning judgment performance. Contrastingly, the ERP results indicated comprehension skill differences in P600 amplitude; high-skilled readers showed stronger familiarity effects for learned words, whereas less-skilled readers did not distinguish between learned words, familiar words, and unlearned words. Evidence from the P600 and N400 illustrated superior learning of meaning when meaning information was coupled with orthography rather than phonology. These results suggest that the availability of word knowledge (orthography, phonology, and meaning) at learning affects subsequent word identification processes when the words are encountered in a new context.  相似文献
