Orthographic knowledge, the general ability to learn, store, and use information about the orthographic form of words (Stanovich & West, 1989), is a crucial skill for supporting literacy. Although the development of first language (L1) orthographic awareness is impacted by the characteristics of a learner’s L1 writing system, relatively little is known about what impact the L1 may have on second language (L2) orthographic awareness. In this study, English language learners from three L1s (French, Hebrew, Mandarin Chinese), plus L1 English speakers, were tested on their English spelling knowledge using a word-pseudohomophone discrimination task. In addition to allowing for the cross-linguistic comparisons, items were designed to examine whether learners had differing performance on pseudohomophones (misspellings) that targeted vowels versus consonants. Consistent with previous research (e.g., McBride-Chang, Bialystok, Cong, & Li, 2004), the L1 Chinese speakers had the highest (L2) accuracy, followed by the L1 Hebrew and the L1 French speakers. The participants from non-alphabetic languages (Hebrew and Chinese) had significantly lower accuracy on items with misspellings involving vowels compared to consonants, and the size of the vowel-consonant accuracy difference varied substantially across L1 groups. The results demonstrate that the characteristics of a learner’s L1 writing system, particularly the existence of vowel and consonant graphemes, impact the development of L2 orthographic knowledge and sensitivity to different types of word misspellings. 相似文献

在现代汉语的许多方言中,前后鼻音是不分的,或者是分不清楚的。有的方言把后鼻音读成前鼻音,有的把前鼻音读成后鼻音。16个鼻韵母占普通话语音系统韵母总数的41％。鼻韵母中90％左右的字是形声字,通过形声字相同的声符可以类推出一系列同声符字的韵尾。掌握鼻韵母形声字韵尾呈现的规律,对于学习和推广普通话具有重要的意义。 相似文献

The present study investigated auditory temporal processing in developmental dyslexia by using a vowel length discrimination
task. Both temporal and phonological processing were studied in a single experiment. Seven German vowel pairs differing in
vowel height were used. The vowels of each pair differed only with respect to vowel length (e.g., /a/ vs. /a:/). In German,
vowel length is characterized by temporal and spectral information. Three types of differences between long versus short vowels
were varied: In the phonological condition, pairs of natural vowels were used, differing in their temporal as well as in their
spectral content. In two temporal conditions, in contrast, a natural vowel was always combined with a manipulated one to keep
spectral content of long and short vowels identical. Thus, the only distinguishing feature between the two vowels was temporal
in nature. Vowels were embedded into monosyllabic pseudo-words and presented successively in a speeded same–different task. Twenty dyslexics and twenty age-matched controls participated in the experiment. In both groups, discrimination accuracy
decreased with increasing vowel height in the two temporal conditions. This result is consistent with former findings on the
relevance of temporal information for vowel length identification in German and extends this topic to cover discrimination
demands. In the phonological condition, groups did not differ in discrimination accuracy. In both temporal conditions, however,
dyslexics performed worse than controls. These results suggest that developmental dyslexia is associated with impairments
in processing basic acoustic parameters of the speech signal, in particular, with a deficit in temporal processing. 相似文献

Phonological analysis of the speech of five children with Down syndrome was compared across single word samples elicited from tests and connected speech samples elicited during play. Analyses indicated that connected speech samples provided fewer total words and word tokens and, in some cases, failed to target certain later developing phonemes. CVCs were similarly represented across single word and connected speech samples, but differences across the sampling conditions included an over‐representation of clusters and an under‐representation of VC and CV forms in single word samples. Overall accuracy for vowels was greater than for consonant production, but no difference in phoneme accuracy was found across the conditions. Differences in phonetic inventories for some subjects indicated the possibility that children may, in their connected speech, avoid phonemes which they have yet to master. Phonological process analysis indicated that differences across the two conditions were restricted to their relative impact on each subject's overall intelligibility. Both similarities and differences with previous studies comparing sampling conditions with other populations are discussed, as are clinical implications. 相似文献

Although children with speech impairment are at increased risk for impaired literacy, many learn to read and spell without difficulty. Around half the children with speech impairment have delayed acquisition, making errors typical of a normally developing younger child (e.g. reducing consonant clusters so that spoon is pronounced as ‘poon’). A smaller group make disordered speech errors that are atypical of normal development (e.g. marking all consonant clusters with /f/ so bread is pronounced as ‘fed’). Profiles of surface speech errors may provide a way of identifying underlying deficits that account for differences in literacy development. This paper investigates the relationship between type of speech impairment, phonological awareness and literacy acquisition. Thirteen children, aged 5;2–7;9, with either delayed or disordered speech and six typically developing controls were compared on tasks measuring onset-rime awareness, letter knowledge, phonological rule knowledge, real and non-word reading. Children with delayed speech development performed like typically developing controls on all phonological awareness and reading measures. Children with speech disorder, who consistently made errors atypical of normal development, had difficulties on all phonological awareness tasks with the exception of syllable awareness. They showed no measurable emergent reading ability. The results suggest the need to differentiate between speech delay and disorder when planning intervention, particularly for literacy skills. 相似文献

In order to investigate the relation between reading accuracy and speech processing, 20 children from grades 2 and 3 who were
skilled in reading were compared with 20 less skilled readers on a speech perception and production task. The two groups of
readers were indistinguishable in their production of the two-syllable words dippy, deepy, tippy, and teepy and in their perception
of the stop consonants /d/ versus /t/. Less skilled readers were significantly less accurate than the skilled readers in a
vowel identification task involving the lax and tense high vowels /i/ and /i/. The error pattern for vowel identification was similar across groups, with both groups making fewer errors when
short and longer segments were alternated. The results imply that vowel phonemes are less securely represented in the perceptual
system of less skilled readers than are consonant phonemes. In addition, the results raise the possibility that a selective
perceptual impairment underlies at least some of the phonemic awareness problems that have been associated with poor reading. 相似文献

This cross-sectional study examined the private speech and task-related activity of 108 school-aged children while they drew pictures of real objects (i.e., a house, a person, and an animal) and make-believe objects (i.e., a house, a person, and an animal) to investigate developmental and task-related changes in self-regulation. Composite scores for each first-grade (N=36), third-grade (N=36), and fifth-grade (N=36) participant were calculated from the repeated raw frequencies of overall private speech and private speech in conjunction with task-related behavior during the two types of drawing activities (i.e., real and make-believe). Scores were then analyzed using regression analysis and 3×2 (Grade×Task Type) ANOVA’s to explore study hypotheses. This study found that: (1) there was a concave curvilinear developmental trend in overall private speech production, (2) participants utilized more private speech during heuristic (i.e., make-believe) drawing tasks than algorithmic (i.e., real) drawing tasks, and (3) school-aged children used private speech in conjunction with task-related behavior in a different manner during the two types of drawing activities. These findings contribute to the Vygotskian perspective regarding the development and function of private speech. 相似文献

A word-spotting task is used in Spanish to test the way in which polysyllabic letter-strings are parsed in this language. Monosyllabic words (e.g., bar) embedded at the beginning of a pseudoword were immediately followed by either a coda-forming consonant (e.g., barto) or a vowel (e.g., baros). In the former case, the embedded word corresponds to the first spoken syllable, whereas it cuts across the syllable boundary in the latter case. Unlike a previous study in English using the same methodology (Taft & Álvarez, 2014), the embedded word was found to be easier to detect when followed by a consonant than a vowel, at least for low-frequency words. It was concluded that phonological recoding is more important in the parsing of Spanish words than English words, where maximization of the coda dominates instead. 相似文献

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

Speech productions of 40 English- and 40 Japanese-speaking children (aged 2-5) were examined and compared with the speech produced by 20 adult speakers (10 speakers per language). Participants were recorded while repeating words that began with "s" and "sh" sounds. Clear language-specific patterns in adults' speech were found, with English speakers differentiating "s" and "sh" in 1 acoustic dimension (i.e., spectral mean) and Japanese speakers differentiating the 2 categories in 3 acoustic dimensions (i.e., spectral mean, standard deviation, and onset F2 frequency). For both language groups, children's speech exhibited a gradual change from an early undifferentiated form to later differentiated categories. The separation processes, however, only occur in those acoustic dimensions used by adults in the corresponding languages. 相似文献

The present study was designed to assess the development of the understanding of certain aspects of grapheme-phoneme correspondences in normally achieving and disabled readers. The correspondences rules were studied using both English words and pseudowords, the latter designed to contain the same features as the real words. The subjects were 76 normally achieving and 32 reading disabled children aged 6 to 14 years. The stimuli included words and pseudowords that tested the following: consonant blends, final e, r-influenced vowels, regular and irregular words, function words, and consistent and inconsistent vowels. When matched for chronological age, the reading disabled children performed significantly more poorly than normally achieving children on all of the tasks involving pseudowords. A similar pattern was found for the words with the exception of the highest frequency words (cvc, final e, consonant blends) at the oldest age level, 11–14 years. In this case, the performance of the oldest reading disabled children was similar to that of the normals on the words, but was still significantly poorer when the stimuli were pseudowords. Complexity and irregularity were significant determinants of difficulty. Comparisons were also made for groups of children matched on reading grade level. Even when the reading disabled and normally achieving children were matched on reading grade, the reading disabled children had significantly more difficulty, particularly with pseudowords. Reading disabled children had significant difficulty in abstracting the basic rules for grapheme-phoneme correspondences in English, and even when they have mastered these rules in connection with real words, they still had difficulty applying these rules to pseudowords. In normal development, the learning of these correspondences appears to be consolidated by approximately 9 years of age. However, reading disabled children appear to have a significant and persistent problem with the learning of basic grapheme-phoneme correspondence rules. 相似文献

This article examined the effect of Modern Standard Arabic orthography on speech production quality (syllable stress and vowels) by 23 Arabic-speaking children with severe or profound hearing loss aged 8-12 years. Children produced 15 one-syllable minimal pairs of words that differed in vowel length (short vs. long) and 20 two-syllable minimal pairs differing in stress pattern. Each word was produced in three tasks: reading partially or fully vowelized words and imitation of aural stimuli. Results showed that fully vowelized words ensured vowel production: high-quality productions appeared on 99%, 74%, and 59% of productions on reading fully vowelized words, partially vowelized words, and on imitation, respectively. Moreover, correct vowel production affected correct consonant production. Correct production of stress was best on reading fully vowelized words, appearing on 54%, 21%, and 33% of productions for fully vowelized words, partially vowelized words, or imitation, respectively. Findings suggest the need to present fully vowelized written texts when teaching speech production to children with hearing loss. Such presentations enable more accurate productions that result in more intelligible speech. 相似文献

The phonological awareness skills of nonreaders were trained using an oddity task (e.g., which word in the series sit, fit, cat has the odd sound in its middle position). As training progressed, the basis of the oddity decision was shifted from rhyming, to consonant onsets, to consonant and vowel phonemes. The words were spoken by a DECtalk speech synthesizer. One of the experimental groups was given printed as well as computer generated speech feedback while the other was given just computer speech feedback. The alternative training control group based their oddity decisions on meaning rather than sound and was also given just computer speech feedback. Only children with low letter-sound knowledge showed pre-test to post-test gains in performance on a rhyming task compared to the control group, and these gains were not influenced by print feedback. In contrast, only children with high letter-sound knowledge, who were given print feedback during learning, showed pre-test to post-test gains in performance on a phoneme deletion task compared to the control group. These results indicate that a combination of high letter-sound knowledge and print feedback facilitates awareness of phonemes among children who cannot yet read or spell, but awareness of rimes is not facilitated by either high letter-sound knowledge or print feedback. Although consistent with bi-directional, causal models of phonological awareness and literacy, these results indicate that the definition of literacy employed by such models may require expansion. This new definition should include proto-literacy — knowledge of letter-sound and other print-sound relationships that are learned before becoming literate and that may influence the acquisition of awareness of some sub-syllabic units of speech.Abbreviations WPPSI

Across several independent studies, infants from a few days to 9 months of age have shown preferences for infant-directed (ID) over adult-directed (AD) speech. Moreover, 4-month-olds have been shown to prefer sine-wave analogs of the fundamental frequency of ID speech, suggesting that exaggerated pitch contours are prepotent stimuli for infants. The possibility of similar preferences by 1-month-olds was examined in a series of experiments, using a fixation-based preference procedure. Results from the first 2 experiments showed that 1-month-olds did not prefer the lower-frequency pitch characteristics of ID speech, even though 1-month-olds were able to discriminate low-pass filtered ID and AD speech. Since low-pass filtering may have distorted the fundamental frequency characteristics of ID speech, 1-month-olds were also tested with sine-wave analogs of the fundamental frequencies of the ID utterances. Infants in this third experiment also showed no preference for ID pitch contours. In the fourth experiment, 1-month-olds preferred a natural recording of ID speech over a version which preserved only its lower frequency prosodic features. From these results, it is argued that, although young infants are similar to older infants in their attraction to ID speech, their preferences depend on a wider range of acoustic features (e.g., spectral structure). It is suggested that exaggerated pitch contours which characterize ID speech may become salient communicative signals for infants through language-rich, interactive experiences with caretakers and increased perceptual acuity over the first months after birth. 相似文献

Generic noun phrases (e.g., "Bats live in caves") are important for expressing knowledge about abstract kinds. Past work has found that parents frequently use generic noun phrases in their speech to young children. However, little is known regarding how children understand these expressions, nor which cues signal generic meaning. The present set of 5 studies examined the influence of linguistic form class (e.g., "What color are dogs?" [generic] versus "What color are the dogs?" [nongeneric]) and of pragmatic context (e.g., "What color are they?" in the presence of either a single exemplar [generic] or multiple exemplars [nongeneric]). Participants were 2-year-olds (N = 42), 3-year-olds (N = 40), 4-year-olds (N = 40), and adults (N = 51). The data indicate that by 2 years of age, children use linguistic form class, and by 3 years of age, children use pragmatic context. These findings demonstrate that young children have begun to understand the distinction between generic and nongeneric noun phrases from a very young age, and that identification of generics is signaled not by formal or pragmatic cues alone, but by a combination of information from both language form and pragmatic context. It is suggested that children make use of multiple linguistic and conceptual cues to acquire and interpret generics. 相似文献

3 experiments are reported, all of which show the crucial importance of the "half" boundary in children's proportional judgments. In the first experiment 4-, 5-, 6-, and 7-year-old children had to judge which of 2 boxes of blue and white bricks was represented in a small picture. The proportion of blue to white bricks was different in the 2 boxes, and the question was whether the children could use these proportions to make their choices. The 6- and 7-year-old children solved the problem much more successfully when the proportions crossed the "half" boundary (e.g., 3/8 blue vs. 5/8 blue). The second experiment showed that discriminations involving half (e.g., 1/2 blue vs. 1/4 blue) are also easier than those that do not cross the "half" boundary for the 6- and 7-year-olds. The third experiment confirmed the results of the first 2 with pictures of different absolute sizes from each other. We conclude that "half" plays a crucial role in children's early proportional reasoning, and that the "half" boundary is to some extent similar to, though not as powerful as, the category boundaries discovered in speech perception. 相似文献
