The research question here was whether whole‐word shape cues might facilitate reading in dyslexia following reports of how normal‐reading children benefit from using this cue when learning to read. We predicted that adults with dyslexia would tend to rely more on orthographic rather than other cues when reading, and therefore would be more affected by word shape manipulations. This prediction was tested in a lexical decision task on words with a flat or a non‐flat outline (i.e. without or with letters with ascending/descending features). We found that readers with dyslexia were significantly faster when reading non‐flat compared with flat words, while typical readers did not benefit from whole‐word shape cues. The interaction of participants' group and word shape was not modulated by word frequency; that is word outline shape facilitated reading for both rare and frequent words. Our results suggest that enhanced sensitivity to orthographic cues is developed in some cases of dyslexia when normal, phonology‐based word recognition processing is not exploited.  相似文献

Previous studies revealing that monolingual and bilingual infants learn similar sounding words with comparable success are largely based on prior investigations involving single‐feature changes in the onset consonant of a word. There have been no investigations of bilingual infants' abilities to learn similar sounding words differentiated by vowels. In the current study, 18‐month‐old bilingual and monolingual infants (n = 90) were compared on their sensitivity to a vowel change when learning the meanings of words. Bilingual infants learned similar sounding words differing by a vowel contrast, whereas monolingual English‐ and Mandarin‐learning infants did not. Findings are discussed in terms of early constraints on novel word learning in bilingual and monolingual infants.  相似文献

This study investigated the phonological contribution during visual word recognition in child readers as a function of general reading expertise (third and fifth grades) and specific word exposure (frequent and less‐frequent words). An intermodal priming in lexical decision task was performed. Auditory primes (identical and unrelated) were used in order to directly activate phonological codes independently of orthographic processing. Overall, the results revealed a widespread phonological priming effect in both grades. There was a significant interaction between grade, priming condition and frequency, revealing that the impact of frequency on identity priming differed between grades. In third grade, the results indicated that the priming effect was greater for less‐frequent than for frequent words. In fifth grade, priming effects were similar for both frequent and less‐frequent words. These findings indicate that print and speech processing systems are interconnected in young readers. Moreover, phonological codes play an important role in word recognition throughout reading development.  相似文献

The present study investigated the effects of lexical homophony on the processing of Japanese two-kanji compound words. Experiment 1 showed that participants took longer to perform lexical decisions for words with a high degree of lexical homophony than those with no homophony. Interestingly, the same inhibitory trend was found in the naming task of Experiment 2. Participants took longer to name words with a high degree of lexical homophony than those with no homophony. The consistency of an inhibitory effect through the two experiments suggests that during naming and lexical decisions for Japanese two-kanji compound words, an orthographic representation activates the phonological representation, which then leads to a rebounding activation of orthographic representations of homophonic forms.  相似文献

The self‐teaching hypothesis suggests that knowledge about the orthographic structure of words is acquired incidentally during reading through phonological recoding. The current study assessed whether visual processing skills during reading further contribute to orthographic learning. French children were asked to read pseudowords. The whole pseudoword letter string was available at once for half of the targets while the pseudoword's sub‐lexical units were discovered in turn for the other half. Then memorisation of the targets’ orthographic form was assessed. Although most pseudowords were accurately decoded, target orthographic forms were recognised more often when the pseudowords entire orthographic sequence was available at once during the learning phase. The whole‐word presentation effect was significant and stable from third to fifth grades. This effect was affected neither by target reading accuracy nor by target reading speed during the learning phase. Results suggest that beyond recoding skills, the ability to process the entire orthographic letter string at once during reading contributes to efficient orthographic learning.  相似文献

A frequency-based vocabulary of 17,602 words was compiled and analyzed in order to group words with recurring syllable and rime patterns for teaching reading. The role of the rime unit (e.g.,ite inkite andinvite) in determining vowel pronunciation was central to the analysis because of the difficulty that the ambiguity of English vowel spelling presents to children who do not learn to read words easily. Vowel pronunciation in each orthographic rime was examined, both for its consistency in all words in which the rime occurs and for regularity, defined as conformity to the most frequent pronunciation for each vowel spelling in each of six orthographic syllable types. Of the 824 different orthographic rimes, 616 occur in rime families as the building blocks of almost all the 43,041 syllables of the words. These rimes account for a striking amount of patterning in the orthography: 436 are both regular and consistent in pronunciation (except where a single exception word occurs); another 55 are consistent but not regular. Of the remaining 125, only 86 have less than a 90 percent level of consistency. The high order of congruence of orthographic and phonological rimes suggests their usefulness as units for teaching reading.  相似文献

Three experiments investigated whether production of low-frequency spellings could be influenced by other words containing those spellings. Participants saw visually-presented primes (Experiment 1) or heard primes presented auditorily and produced their spelling (Experiments 2 and 3). Primes either shared both orthography and phonology (e.g., chapl ai n) or only orthography (e.g., ord ai n) with the target word (e.g., porcel ai n). Following the primes, participants attempted to produce the correct spellings of auditorily-presented target words containing low-frequency spellings, such as the ai in porcelain. Participants correctly spelled the targets’ low-frequency spelling more often when preceded by either type of prime, relative to unprimed targets. Furthermore, priming only occurred when the prime’s spelling was produced correctly; primes spelled incorrectly reduced the correct production of target spellings. These results suggest that unlike the priming of nonwords, the basis of lexical priming of real words is orthographic, resulting from the priming of specific graphemes that increases the probability of reactivating the same spelling pattern in the target.

The present study addressed the issue of syllable activation during visual recognition of French words. In addition, it was investigated whether word orthographic information underlies syllable effects. To do so, words were selected according to the frequency of their first syllable (high versus low) and the frequency of the orthographic correspondence of this syllable (high versus low). For example, the high-frequency syllable /ã/ is frequently transcribed by the orthographic cluster an, but infrequently transcribed by han in French. A lexical decision task was performed by skilled readers (Experiment 1) and beginning readers in Grade 5 (Experiment 2). Results yielded an inhibitory effect of syllable frequency in both experiments. Moreover, the reliable interaction between syllable frequency and orthographic correspondence frequency indicated that the syllable frequency effect was influenced by orthographic characteristics of syllables. Finally, data showed that the interaction between phonological and orthographic variables was modified with reading experience. The results are discussed in current models of visual word recognition.  相似文献

Two groups of undergraduate students, matched for reading skill but differing in spelling ability, participated in three experiments with the aim of exploring the causes of differences in spelling skill in this population. In the first experiment participants were presented with a range of tasks to investigate the possibility that the poor spellers had poorer phonological abilities than the good spellers. No significant differences were observed. In Experiment 2, a lexical decision task was used. The words in the task differed in orthographic neighbourhood size (N) and frequency. Analysis of the latencies revealed effects of frequency and N, but the effect of spelling group was not significant and neither was the interaction with N. Analysis of the errors revealed that the poor spellers made significantly more errors than the good spellers. In Experiment 3 participants were asked to identify the letters in briefly presented words and non‐words. There was a significant effect of stimulus type in favour of words. Poor spellers made more errors in the task than the good spellers, although the difference was restricted to non‐words. Finally, an analysis of the errors made in spelling to dictation by the two groups was carried out. This revealed that the poor spellers were more likely than the good spellers to make errors that were not phonologically plausible and that differed markedly from the target. Overall, the results are interpreted in terms of a partial orthographic representations explanation of poor spelling in good readers.  相似文献

Consonants and vowels differentially contribute to lexical acquisition. From 8 months on, infants' preferential reliance on consonants has been shown to predict their lexical outcome. Here, the predictive value of German-learning infants' (n = 58, 29 girls, 29 boys) trajectories of consonant and vowel perception, indicated by the electrophysiological mismatch response, across 2, 6, and 10 months for later lexical acquisition was studied. The consonant-perception trajectory from 2 to 6 months (β = −2.95) and 6 to 10 months (β = −.91), but not the vowel-perception trajectory, significantly predicted receptive vocabulary at 12 months. These results reveal an earlier predictive value of consonant perception for word learning than previously found, and a particular role of the longitudinal maturation of this skill in lexical acquisition.  相似文献

Early in development, many word‐learning phenomena generalize to symbolic gestures. The current study explored whether children avoid lexical overlap in the gestural modality, as they do in the verbal modality, within the context of ambiguous reference. Eighteen‐month‐olds’ interpretations of words and symbolic gestures in a symbol‐disambiguation task (Experiment 1) and a symbol‐learning task (Experiment 2) were investigated. In Experiment 1 (N = 32), children avoided verbal lexical overlap, mapping novel words to unnamed objects; children failed to display this pattern with symbolic gestures. In Experiment 2 (N = 32), 18‐month‐olds mapped both novel words and novel symbolic gestures onto their referents. Implications of these findings for the specialized nature of word learning and the development of lexical overlap avoidance are discussed.  相似文献

ABSTRACT

Spelling errors are typically thought of as an effect of a word’s weak orthographic representation in an individual mind. What if existence of spelling errors is a partial cause of effortful orthographic learning and word recognition? We selected words that had homophonic substandard spelling variants of varying frequency (e.g., innocent and inocent occur in 69% and 31% of occurrences of the word, respectively). Conventional spellings were presented for recognition either in context (Experiment 1, eye-tracking sentence reading) or in isolation (Experiment 2, lexical decision). Words elicited longer fixation durations and lexical decision latencies if there was more uncertainty (higher entropy) regarding which spelling is a preferred one. The inhibitory effect of frequency was not modulated by spelling or other reading skill. This finding is in line with theories of learning that predict spelling errors to weaken associations between conventional spellings and the word’s meaning.  相似文献

Morphological analysis of words has been shown to characterize skilled reading. A manipulation on the presentation of words, designed to encourage this process, was examined in dyslexic readers. Fifty-eight Hebrew-speaking university students with dyslexia were divided into three groups. One underwent a very short-term morpheme-based training, consisting of a time-restricted exposure to the root morphemes of words presented in a lexical decision task. The rest of the words’ letters remained on screen until a response. Another group received a control training consisting of the same procedure, except that the presentation of a nonmorphological orthographic unit was manipulated. Two untrained control groups, of dyslexic readers and of typical readers (n = 20), received pre- and posttest measures without training. The results suggest modest but positive effects on reading and spelling following the morpheme-based training, thereby suggesting that the morphological manipulation examined should be integrated in more intensive trainings.  相似文献

The study investigates dyslexic and normal Hebrew readers’ perception of words containing a vowel letter in different orthographic and morphological contexts. In the first experiment, 72 undergraduate education students (half diagnosed with reading disabilities and half normal readers) were asked to judge pointed words with different morphological structures with and without the grapheme W. Half of the words had consistent (obligatory) W and half had inconsistent (optional) W. In the second experiment, the same procedure was repeated using the same words without pointing marks. Response latencies and accuracy were measured. In both experiments, dyslexic readers did less well than normal readers. They had lower scores on accurate lexical decisions and they took more time over these decisions. They also exhibited some deviant patterns, indicating that they cannot make use of orthographic and morphological cues that are available to normal readers, especially in the pointed experiment. Processing pointed words placed a heavier cognitive burden on the dyslexic readers. These findings are in line with other studies of adult dyslexic reader/writers, and support a reading / spelling processing model, which claims that internal orthographic representations of words are increasingly strengthened with each exposure during reading, but not all graphemes are strengthened equally. The general implication is that the ambiguities that exist in the relationships between orthography, phonology, and morphology underlie spelling knowledge, and are particularly difficult for dyslexic readers.  相似文献

The study uses an orthographic judgment task to evaluate the efficiency of the lexical reading route in Italian dyslexic children. It has been suggested that Italian dyslexic children rely prevalently on the sub-word-level routine for reading. However, it is not easy to test the lexical reading route in Italian directly because of the lack of critical items (irregular words), so visual lexical decision tasks and the comprehension/detection of pseudo-homophones are often used. While the former may also be solved on the basis of visual familiarity or phonological re-codification, the latter also involves conceptual and syntactic skills. Eleven dyslexic children participated in the study, performing an orthographic judgment task on stimuli with two phonologically plausible spellings, of which only one was orthographically correct. Their performance was compared with those of 11 proficient readers. The dyslexic children showed selective impairment in detecting phonologically plausible errors, but their performance was normal when required to judge errors inserted in words with regular orthography, i.e., devoid of orthographic ambiguity, and for which a sub-word-level reading procedure is sufficient to guarantee a good performance. Overall, data are coherent with a diagnosis of surface dyslexia, with most children showing defective orthographic lexical processing.

The aim of this study was to investigate the role of the syllable in visual recognition of French words in Grade 6. To do so, the syllabic congruency effect was examined in the lexical decision task combined with masked priming. Target words were preceded by pseudoword primes sharing the first letters that either corresponded to the syllable (congruent condition) or not (incongruent condition). A reliable syllable congruency was found. Children were faster to recognize words when the prime matched for the first syllable. These results are discussed in interactive activation models including syllables and in the dual-route approach.  相似文献

Although children develop categorical speech perception at a very young age, the maturation process remains unclear. A cross-sectional study in Mandarin-speaking 4-, 6-, and 10-year-old children, 14-year-old adolescents, and adults (n = 104, 56 males, all Asians from mainland China) was conducted to investigate the development of categorical perception of four Mandarin phonemic contrasts: lexical tone contrast Tone 1-2, vowel contrast /u/−/i/, consonant aspiration contrast /p/−/ph/, and consonant formant transition contrast /p/−/t/. The results indicated that different types of phonemic contrasts, and even the identification and discrimination of the same phonemic contrast, matured asynchronously. The observation that tone and vowel perception are achieved earlier than consonant perception supports the phonological saliency hypothesis.  相似文献

Two experiments were conducted to compare the development of orthographic representations in children learning to read English and Greek. Nonsense words that either shared both orthography and phonology at the level of the rhyme with real words (comic-bomic), phonology only (comic-bommick), or neither (dilotaff) were created for each orthography. Experiment 1 compared children’s reading of bisyllabic and trisyllabic nonsense words likebomic vs.bommick, taffodil vs.tafoddyl, and found a significant facilitatory effect of orthographic rhyme familiarity for English only. Experiment 2 compared children’s reading of trisyllabic nonsense words that either shared rhyme phonology with real words (tafoddyl) or did not (dilotaff). Significant facilitation in reading accuracy was found for shared rhyme phonology in English, with a significant speed advantage in Greek. These results are interpreted in terms of the level of phonology that is represented in the orthographic recognition units being developed by children who are learning to read more and less transparent orthographies.  相似文献
