Two lexical decision experiments are reported that investigate whether the same segmentation strategies are used for reading printed English words and fingerspelled words (in American Sign Language). Experiment 1 revealed that both deaf and hearing readers performed better when written words were segmented with respect to an orthographically defined syllable (the Basic Orthographic Syllable Structure [BOSS]) than with a phonologically defined syllable. Correlation analyses revealed that better deaf readers were more sensitive to orthographic syllable representations, whereas segmentation strategy did not differentiate the better hearing readers. In contrast to Experiment 1, Experiment 2 revealed better performance by deaf participants when fingerspelled words were segmented at the phonological syllable boundary. We suggest that English mouthings that often accompany fingerspelled words promote a phonological parsing preference for fingerspelled words. In addition, fingerspelling ability was significantly correlated with reading comprehension and vocabulary skills. This pattern of results indicates that the association between fingerspelling and print for adult deaf readers is not based on shared segmentation strategies. Rather, we suggest that both good readers and good fingerspellers have established strong representations of English and that fingerspelling may aid in the development and maintenance of English vocabulary.  相似文献

Deaf people often achieve low levels of reading skills. The hypothesis that the use of phonological codes is associated with good reading skills in deaf readers is not yet fully supported in the literature. We investigated skilled and less skilled adult deaf readers' use of orthographic and phonological codes in reading. Experiment 1 used a masked priming paradigm to investigate automatic use of these codes during visual word processing. Experiment 2 used a serial recall task to determine whether orthographic and phonological codes are used to maintain words in memory. Skilled hearing, skilled deaf, and less skilled deaf readers used orthographic codes during word recognition and recall, but only skilled hearing readers relied on phonological codes during these tasks. It is important to note that skilled and less skilled deaf readers performed similarly in both tasks, indicating that reading difficulties in deaf adults may not be linked to the activation of phonological codes during reading.  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

In order to become expert readers of an alphabetical language like French, students must develop and adequately use phonological knowledge. Considering that the phonological knowledge used in reading largely comes from knowledge of the oral language, what happens when the oral language is not accessible, as is the case for many deaf children? In this study, graphophonemic and syllabic processes in pseudoword reading were assessed with a similarity judgment task. Gestual deaf subjects aged 10–18 years old (N = 24) were compared to 24 age-matched hearing subjects. The results show that deaf readers are less sensitive to the graphemic and the syllabic structures of pseudo-words than hearing readers. In deaf subjects, the results are different than chance-level in the 13–15 and the 16–18-year-old groups. These results indicate that gestual deaf readers can develop phonological knowledge even in settings where sign language is promoted.  相似文献

Insufficient knowledge of the subtle relations between words’ spellings and their phonology is widely held to be the primary limitation in developmental dyslexia. In the present study the influence of phonology on a semantic-based reading task was compared for groups of readers with and without dyslexia. As many studies have shown, skilled readers make phonology-based false-positive errors to homophones and pseudohomophones in the semantic categorization task. The basic finding was extended to children, teens, and adults with dyslexia from familial and clinically-referred samples. Dyslexics showed the same overall pattern of phonology errors and the results were consistent across dyslexia samples, across age groups, and across experimental conditions using word and nonword homophone foils. The dyslexic groups differed from chronological-age matched controls by having elevated false-positive homophone error rates overall, and weaker effects of baseword frequency. Children with dyslexia also made more false-positive errors to spelling control foils. These findings suggest that individuals with dyslexia make use of phonology when making semantic decisions both to word homophone and non-word pseudohomophone foils and that dyslexics lack adequate knowledge of actual word spellings, compared to chronological-age and reading-level matched control participants.  相似文献

Rhyme generation in deaf students: the effect of exposure to cued speech   总被引:1,自引:0,他引:1  
This study compares the rhyme-generation ability of deaf participants with severe to profound hearing losses from cued speech (CS) and non-cued speech (NCS) backgrounds with a hearing comparison group for consistent orthography-to-phonology (O-P) rhyming elements, or rimes (e.g., -ail in sail is always pronounced the same), and inconsistent orthography-to-phonology (I-O-P) rhyming elements where the orthographic rime (e.g., -ear) has different pronunciations in words such as bear, and rear. Rhyming accuracy was better for O-P target words than for I-O-P target words. The performance of the deaf participants from CS backgrounds, although falling between that of the hearing and the NCS groups, did not differ significantly from that of the hearing group. By contrast, the performance of the NCS group was lower than that of the hearing group. Hearing and CS participants produced more orthographically different responses (e.g., blue-few), whereas participants from the NCS group produced more responses that are orthographically similar (e.g., blue-true), indicating that the hearing and CS groups rely more on phonology and the NCS group more on spelling to generate rhymes. The results support the use of cued speech for developing phonological abilities of deaf students to promote their reading abilities.  相似文献

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

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

We investigated whether children who were learning to read simultaneously in English and French activate phonological representations from only the language in which they are reading or from both of their languages. Children in French Immersion programs in Grade 3 were asked to name aloud cognates, interlingual homographs, interlingual homophones, and matched control words. Half of the participants performed the task in English, their first oral language, and half performed the task in French. Control monolingual children in each language were also tested. In the French reading task, fewer errors were observed for cognates and interlingual homophones than for matched control words, whereas more errors were produced for interlingual homographs than matched controls. Only the inhibitory interlingual homograph effect was observed in the English reading task. These data provide evidence that phonological activation in bilinguals is not language selective. The locus of each of these effects in the bilingual word recognition system is discussed.  相似文献

Strategy usage among deaf and hearing readers   总被引:1,自引:0,他引:1  
High school youths who were prelingually and profoundly deaf, hearing elementary-school-age youths, and hearing reading-disabled high school youths read expository texts and filled in deleted words and phrases. After making word replacements, they explained their decisions in sign or verbally. As expected, the hearing youths had an easier time filling in the deleted portions and explaining what strategies they were using. While the deaf youths reported using similar strategies as the hearing youths, the frequency of each type of strategy differed. Deaf readers more often relied on rereading and background knowledge, while the hearing readers made greater use of context clues. The results suggest that instruction for deaf readers should include more effective comprehension strategies.  相似文献

The sources of knowledge that individuals use to make similarity judgments between words are thought to tap underlying phonological representations. We examined the effects of perceptual similarity between stimuli on deaf children's ability to make judgments about the phonological similarity between words at 3 levels of linguistic structure (syllable, rhyme, and phoneme). Manipulation of stimulus contrasts (acoustic, visual/orthographic, tactile/motoric) allowed a finer-grained estimate of the sources of knowledge that deaf individuals use to make similarity judgments between words. The results showed that the ability to make syllable-, rhyme-, and phoneme-level judgments was not tied to "phonological" facilitation when these conditions are contrasted. These findings are inconsistent with long-held assumptions of "functional" equivalence between "heard" and "seen" speech in the development of phonological representations in deaf learners. We argue that previous studies reporting evidence for phonological effects in similarity judgments have failed to sufficiently control for alternative sources of sensory information, namely, visual and tactile/motoric.  相似文献

This study examined the extent to which adultdyslexic readers exhibit concurrent deficitsfor phonological, orthographic and cross-modalword representations, and the relationshipbetween these deficits and decoding ability.Participants were 18 phonological dyslexics and19 normal readers at college level. Compared tonormal readers, dyslexics exhibitedsignificantly slower reaction times acrosstasks, and were less accurate on the unimodalorthographic task. Word pattern processing wasmore extensively related to decoding abilityamong dyslexic as compared to normal readers,but more robustly related to baseline measuresof phonological and orthographic processingamong normal readers. The results are discussedin the context of integrating the phonologicaland orthographic aspects of words, speed ofprocessing deficits, and the importance of taskselection when assessing adult dyslexicpopulations.  相似文献

This study aimed at examining whether deaf children process written words on the basis of phonological units. In French, the syllable is a phonologically and orthographically well-defined unit. French deaf children and hearing children matched on word recognition level were asked to copy written words and pseudo-words. The number of glances at the item, copying duration, and the locus of the first segmentation (i.e., after the first glance) within the item were measured. The main question was whether the segments copied by the deaf children corresponded to syllables as defined by phonological and orthographic rules.The results showed that deaf children, like hearing children, used syllables as copying units when the syllable boundaries were marked both by orthographic and phonological criteria. However, in a condition in which orthographic and phonological criteria were differentiated, the deaf children did not perform phonological segmentations while the hearing children did. We discuss two explanatory hypotheses. First, items in this condition were difficult to decode for deaf children; second, orthographic units were probably easier to process for deaf children than phonological units because of a lack of automaticity in their phonological conversion processes for pseudo-words. Finally, incidental observations during the experimental task raised the question of the use of fingerspelled units.  相似文献

In the present study, the effect of phonological and working memory mechanisms involved in spelling Italian single words was explored in two groups of children matched for grade level: a group of normally hearing children and a group of pre-verbally deaf children, with severe-to-profound hearing loss. Three-syllable and four-syllable familiar words were presented to the two groups for spelling to dictation. Three conditions were used: simple spelling, concurrent articulation, and foot tapping. Verbal digit span was also assessed. Overall, the performance of deaf children tended to be lower compared to hearing children, but not significantly so. Concurrent articulation produced more errors than tapping in both groups. Regression analyses showed that the main predictor in all three tasks was school level, however the proportion of variance explained by this factor was much greater in the dual tasks, in particular in concurrent articulation. Qualitative analyses of errors showed a worse performance of deaf children, with a greater proportion of mixed errors compared to hearing children. They also showed a greater proportion of phonologically plausible errors compared to hearing children, presumably due to their deprived auditory representation, and/or to phonological representations that rely to a large extent on lip reading and kinesthetic and visual perception of articulatory gestures.  相似文献

We examined the nature of and factors related to adolescents’ reading difficulties in a highly transparent orthography. We compared word, pseudoword, and text reading speed and accuracy, rapid naming (RAN) and phonological processing between poor readers (n?=?80) and normally developing readers (n?=?189). Reading problems were manifested in reading speed and in timed pseudoword reading accuracy. RAN predicted speed, and phonological processing predicted accuracy of reading in both groups. Among poor readers, RAN also explained reading accuracy. For the normally developing sample, phonological processing also predicted reading speed.  相似文献

This study aimed to determine whether the reading skills of third‐grade schoolchildren are associated with their preferences for semantic, phonological, and shape competitors (images or printed words) after being exposed to a spoken critical word. Two groups of children participated: skilled readers and less‐skilled readers. Through a language‐mediated visual search, children's fixations on the three competitors and a distractor were measured. When looking at images, both groups of readers preferred to look at the semantic competitor. When reading words, both groups showed a preference for the phonological competitor, but only skilled readers were sensitive to semantic information. These results suggest that early reading skills influence access to different types of representations in response to hearing a word, and they confirm the existence of a cascaded activation of information retrieval in childhood.  相似文献

Two experiments investigated the effect of kanji morphemic homophony on lexical decision and naming. Effects were examined from both the left-hand and right-hand positions of Japanese two-kanji compound words. The number of homophones affected the processing of compound words in the same way for both tasks. For left-hand kanji, fewer morphemic homophones led to faster lexical decision and whole-word naming. For right-hand kanji, the number of morphemic homophones did not affect either lexical decision or naming. This effect of homophonic density suggested that, when a kanji-compound word is to be processed, phonological information of its kanji constituents is automatically activated and reverberates back to generate a series of orthographic representations of kanji morphemic homophones, but not in a completely parallel fashion.  相似文献

This study examined word identification, phonological recoding efficiency, familiar word reading efficiency, orthographic choice for familiar words and serial naming speed as potential correlates of orthographic learning following silent reading in third‐grade children. Children silently read a series of short stories, each containing six repetitions of a different target non‐word. They subsequently read target non‐words faster than homophones and preferred target non‐words to homophones in an orthographic choice task, indicating that they had formed functional orthographic representations of the target non‐words through phonologically recoding them during silent story reading. Target non‐word orthographic choice was correlated with all measures bar non‐symbol naming speed. The association between phonological recoding efficiency and orthographic learning lends support to the hypothesis that self‐teaching occurs through phonological recoding even in silent reading. Our findings were not generally consistent with the view that serial naming speed assesses orthographic learning aptitude.  相似文献

The objectives of this series of 3 studies were (a) to evaluate whether French-speaking children mainly use phonological mediation in the first stage of reading acquisition in a silent-reading task and (b) to examine the role of phonological processing in the construction of the orthographic lexicon. Forty-eight French children were followed from kindergarten to the end of Grade 2. Their phonological skills were assessed using a semantic categorization task with homophone and visual foils (Study 1); their orthographic skills were assessed using a choice task involving a correct exemplar, a homophone, and a visual foil (Study 2). In the semantic categorization task, the differences between the visual and homophone foils increased with time, as the homophone foils were more and more likely to be chosen. In the orthographic choice task, performance improved with time, but errors were more likely to involve homophone foils. The results obtained by two subgroups of children who differed in their level of orthographic expertise at the end of Grade 2 (Study 3) indicated that, 1 year earlier (at the end of Grade I), the future "expert" spellers were more likely than the future "poor" spellers to use phonological processing in silent reading (semantic categorization task). Moreover, in Grade 1, future expert spellers' phonological skills in reading aloud and in spelling from dictation (pseudoword tasks) were better than those of future poor spellers, and future expert spellers also had better phonological awareness skills at the beginning of the last year of kindergarten. These results suggest that French-speaking children use phonological mediation in silent-reading tasks and that phonological processing contributes to the construction of the orthographic lexicon.  相似文献
