The nature of the relations among morphological awareness, vocabulary and word reading in Chinese children remains relatively unclear. The present study aimed to distinguish between sublexical morphological awareness, referring to the ability to use the meaning cues of semantic radicals embedded in a compound character, and lexical level morphological awareness, defined as the ability to understand and manipulate single characters (i.e., morphemes) comprising Chinese compound words, on word reading. We also examined the role of vocabulary knowledge on the relation between morphological awareness and word reading at both the sublexical and lexical levels. A group of 172 Chinese second graders were administered measures of sublexical and lexical level morphological awareness, vocabulary knowledge, phonological awareness, orthographic knowledge, nonverbal ability, and word reading. Both sublexical and lexical levels of morphological awareness were moderately correlated with word reading. Vocabulary knowledge appeared to partially mediate the effect of sublexical morphological awareness on word reading, but it fully mediated the effect of lexical level morphological awareness on word reading. These results suggest that sublexical and lexical level morphological awareness play distinct roles in Chinese word reading; vocabulary knowledge is an important factor influencing the relation between morphological awareness and word reading in Chinese. 相似文献

This article examines the relationship between individual differences in speech perception and sublexical/phonological processing in reading. We used an auditory phoneme identification task in which a?/ba/-/pa/?syllable continuum measured sensitivity to classify participants into three performance groups: poor, medium, and good categorizers. A lexical decision task manipulated syllable and word frequency. We found that the two tasks were associated. Poor categorizers did not present the typical syllable frequency effect; however, the other groups were sensitive to phonological information to differing degrees and showed the inhibitory syllable frequency effect only for low-frequency words. These results suggest that auditory phoneme identification efficiency may be related to the sublexical processes involved in reading words. 相似文献

This study investigated the reading and reading-related skills of 15 French-speaking adults with dyslexia, whose performance
was compared with that of chronological-age controls (CA) and reading-level controls (RL). Experiment 1 assessed the efficiency
of their phonological reading-related skills (phonemic awareness, phonological short-term memory, and rapid automatic naming
(RAN)) and experiment 2 assessed the efficiency of their lexical and sublexical (or phonological) reading procedures (reading
aloud of pseudowords and irregular words of different lengths). Experiment 1 revealed that adults with dyslexia exhibited
lower phonological reading-related skills than CAs only, and were better than RL controls on the RAN. In experiment 2, as
compared with RL controls, only a deficit in the sublexical reading procedure was observed. The results of the second experiment
replicated observations from English-language studies but not those of the first experiment. Several hypotheses are discussed
to account for these results, including one related to the transparency of orthographic systems. 相似文献

We examined (a) how rapid automatized naming (RAN) components—articulation time and pause time—predict reading accuracy and reading fluency in Grades 4 and 5, and (b) what cognitive-processing skills (phonological processing, orthographic processing, or speed of processing) mediate the RAN–reading relationship. Sixty children were followed from Grade 3 to Grade 5 and were administered RAN (Letters and Digits), phonological processing, lexical and sublexical orthographic processing, speed of processing, reading accuracy, and fluency tasks. Pause time was highly correlated with reading fluency and shared more of its predictive variance with lexical orthographic processing and speed of processing than with phonological processing. Articulation time also predicted reading fluency, and its contribution was mostly independent from other cognitive-processing skills. Implications for the relationship between RAN and reading are discussed. 相似文献

There is an ongoing debate whether deaf individuals access phonology when reading, and if so, what impact the ability to access phonology might have on reading achievement. However, the debate so far has been theoretically unspecific on two accounts: (a) the phonological units deaf individuals may have of oral language have not been specified and (b) there seem to be no explicit cognitive models specifying how phonology and other factors operate in reading by deaf individuals. We propose that deaf individuals have representations of the sublexical structure of oral-aural language which are based on mouth shapes and that these sublexical units are activated during reading by deaf individuals. We specify the sublexical units of deaf German readers as 11 "visemes" and incorporate the viseme set into a working model of single-word reading by deaf adults based on the dual-route cascaded model of reading aloud by Coltheart, Rastle, Perry, Langdon, and Ziegler (2001. DRC: A dual route cascaded model of visual word recognition and reading aloud. Psychological Review, 108, 204-256. doi: 10.1037//0033-295x.108.1.204). We assessed the indirect route of this model by investigating the "pseudo-homoviseme" effect using a lexical decision task in deaf German reading adults. We found a main effect of pseudo-homovisemy, suggesting that at least some deaf individuals do automatically access sublexical structure during single-word reading. 相似文献

We report a case study of an acquired dyslexic subject, who on tasks standardly used to assess acquired dyslexia showed no evidence of having any access to sublexical phonological information. However, on a lexical decision task, he showed normal effects of spelling regularity for low-frequency words. Since this effect is typically attributed to the use of sublexical phonological information in word recognition, it appears that sublexical phonological processing is occurring for this subject. The spelling regularity effect is discussed with respect to models of written word recognition and to acquired dyslexia. It is suggested that the reason for the discrepancy in test results may be that the types of explicit tasks previously used in the neuropsychological literature on dyslexia, which require conscious awareness of phonological representations, are not sensitive to implicit processing. 相似文献

This study examined the role of context effects in the processing of homophones in Chinese and Chinese-English bilingual speech. In Experiment 1, Chinese speakers were presented with successively gated portions of a homophone in a sentence context, and they identified the homophone on the basis of its increasing acoustic information. In Experiment 2, Chinese-English bilinguals were presented with a cross-language homophone in a sentence context, and they named a visual probe that had or did not have phonological overlaps with the homophone. Results indicate that prior sentence context has an early effect on the disambiguation of various homophone meanings, shortly after the acoustic onset of the word, in both monolingual and bilingual situations. The results are accounted for by interactive activation models of lexical processing, in which the recognition of a homophone is a result of the interactions among phonological, lexical, and contextual information at an early stage. 相似文献

Recent eye movement experiments offer preliminary evidence that skilled readers activate word‐level prosodic information when silently reading sentences. This paper reviews the role of eye movements during reading as well as the preliminary evidence for prosodic processing. A new experiment examines whether prosodic processing differs for high and low frequency words. Readers' eye movements were monitored while reading target words presented in sentences preceded by parafoveal previews that either contained the exact initial syllable of the target (i.e. the congruent preview condition) or the initial syllable plus the next letter (i.e. the incongruent preview condition). Reading times on high frequency words did not differ in the congruent and incongruent preview conditions, but reading times on low frequency words were faster in the congruent condition. The implications of the present result and previous studies are discussed in terms of phonological hub theory, which is a production‐based theory of word recognition during skilled silent reading. 相似文献

In two reading level design experiments, matched groups of normal and poor readers were compared with regard to their use of phonological and orthographic information. Experiment 1 used a semantic decision task similar to the task described in the study of Jarvella & Snodgrass (1974). Experiment 1 was aimed to assess the way normal and poor readers, matched on reading level, automatically process phonological and orthographic incongruencies when comparing the singular and plural of nouns. Experiment 2 investigated the automatized processing of uppercase-lowercase letter incongruencies in a same-different task using words and pseudowords. It assessed the role of letter feature cues involved in the initial identification process. Experiment 1 demonstrated that poor readers needed more time for evaluating phonologically incongruent word pairs. No independent effect of orthographic incongruency was found. Experiment 2 showed that, if compared with reading age matched normals, poor readers had more problems with evaluating uppercase-lowercase incongruencies. This orthographic processing problem was particularly prominent when pseudowords were presented. It is concluded that poor readers not only have phonological processing problems, but also have difficulties at the orthographic processing level. 相似文献

The present study examined the use of statistical cues for word boundaries during Chinese reading. Participants were instructed
to read sentences for comprehension with their eye movements being recorded. A two-character target word was embedded in each
sentence. The contrast between the probabilities of the ending character (C2) of the target word (C12) being used as word
beginning and ending in all words containing it was manipulated. In addition, by using the boundary paradigm, parafoveal overlapping
ambiguity in the string C123 was manipulated with three types of preview of the character C3, which was a single-character
word in the identical condition. During preview, the combination of C23′ was a legal word in the ambiguous condition and was
not a word in the control condition. Significant probability and preview effects were observed. In the low-probability condition,
inconsistency in the frequent within-word position (word beginning) and the present position (word ending) lengthened gaze
durations and increased refixation rate on the target word. Although benefits from the identical previews were apparent, effects
of overlapping ambiguity were negligible. The results suggest that the probability of within-word positions had an influence
during character-to-word assignment, which was mainly verified during foveal processing. Thus, the overlapping ambiguity between
parafoveal words did not interfere with reading. Further investigation is necessary to examine whether current computational
models of eye movement control should incorporate statistical cues for word boundaries together with other linguistic factors
in their word processing system to account for Chinese reading. 相似文献

The present study examined whether sublexical morphological processing takes place during visual word-recognition in Hebrew, and whether morphological decomposition of written words depends on lexical activation of the complete word. Furthermore, it examined whether morphological processing is similar when reading Hebrew as a first language (L1) or as a second language (L2), and whether L1’s morphological background, Semitic or Indo-European, modulates morphological processing in L2 Hebrew (a Semitic language), among proficient readers. To reveal the sublexical processing of the Hebrew morphemes, the Root (R) and the Pattern (P), a lexical-decision task was conducted, in which all critical stimuli were non-word letter-strings manipulated to include or exclude real Hebrew morphemes. Different combinations of real (+) and pseudo (?) morphemes yielded four types of non-words (+R+P; +R?P; ?R+P, ?R?P). Three groups of proficient Hebrew readers were tested: L1 Hebrew, L1 English-L2 Hebrew, and L1 Arabic-L2 Hebrew. Results demonstrated significant differences in latency and accuracy of responses to the four morphological conditions, indicating that sublexical morphological processing occurs during visual word-recognition of morphologically structured letter-strings in Hebrew. Importantly, the activation of real Hebrew morphemes occurred in non-word stimuli, indicating that morphological processing in Hebrew is separable from lexical activation. Moreover, the same pattern of results was observed in all three L1 groups, indicating that proficient L2 readers exhibit morphological processing strategies that are tuned to the L2 morphology, regardless of their L1 background. 相似文献

Two experiments demonstrate that individual differences among normal adult readers, including lexical quality, are expressed in silent reading at the word level. In the first of two studies we identified major dimensions of variability among college readers and among words using factor analysis. We then examined the effects of these dimensions of variability on eye movements during paragraph reading. More experienced readers (who also were higher in reading speed) read words more quickly, especially less frequent words, while readers with higher lexical knowledge showed shorter early fixations, especially for more frequent words. These results suggest that individual differences in reading may reflect differences in the quality of lexical representations and in reading experience, which is a source of lexical quality. In a second study, we controlled the lexical knowledge readers obtained from new words through a training paradigm that varied exposure to a word’s orthographic, phonological, and meaning constituents. Training exposure to orthographic and phonological constituents affected first pass reading measures, and phonological and meaning training affected second pass measures. Incomplete knowledge of word components slowed first pass reading times, compared to both more complete knowledge and no knowledge. Training effects were mediated by individual differences, pointing to lexical quality and reading experience—which, combined reflect reading expertise—as important in word reading as part of text reading. 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 role of letters and syllables in typical and dysfluent second grade reading in Finnish, a transparent orthography, was assessed by lexical decision and naming tasks. Typical readers did not show reliable word length effects in lexical decision, suggesting establishment of parallel letter processing. However, there were small effects of word syllable structure in both tasks suggesting the presence of some sublexical processing also. Dysfluent readers showed large word length effects in both tasks indicating decoding at the letter-phoneme level. When lexical access was required in a lexical decision task, dyslexics additionally chunked the letters into syllables. Response duration measure revealed that dysfluent readers even sounded out the words in phoneme-by-phoneme fashion, depending on the task difficulty. This letter-by-letter decoding is enabled by the transparent orthography and promoted by Finnish reading education. 相似文献

运用定量研究的方法调查了汉语儿童英语单词命名中的策略使用情况。128名小学六年级的学生参加了此次实验。被试给混杂在规则和不规则单音节和双音节英语词汇表中的高频和低频词命名。不规则词语使读者倾向于使用词汇路径,而纯规则词语构成的词汇表却使目标词中的非词汇信息得到了更有效的运用。当词汇表主要由规则或不规则双音节填塞词构成时,词频效应就达到了。相对于单音节规则词语,当填塞词是单音节不规则词语时,频率效应显著增大。此研究结果拓展了之前的浅正字法研究,这表明作为第二语言学习者的汉语儿童在较深的正字法,即英语的单词命名中也能对音位和词汇信息灵活地加以运用。 相似文献

We studied the transition in predominant reading strategy from serial sublexical processing to more parallel lexical processing as a function of word familiarity in German children of Grades 2, 3, 4, and adults. High-frequency words, low-frequency words, and nonwords of differing length were embedded in sentences and presented in an eye-tracking paradigm. The size of the word length effect was used as an indicator of serial sublexical decoding. When controlling for the generally higher processing times in younger readers, the effect of length over reading development was not direct but modulated by familiarity: Length effects were comparable between items of differing familiarity for Grade 2, whereas from Grade 3, length effects increased with decreasing familiarity. These findings suggest that Grade 2 children apply serial sublexical decoding as a default reading strategy to most items, whereas reading by direct lexical access is increasingly dominant in more experienced readers. 相似文献

Albanian is an Indo-European language with a shallow orthography, in which there is an absolute correspondence between graphemes and phonemes. We aimed to know reading strategies used by Albanian disabled children during word and pseudoword reading. A pool of 114 Kosovar reading disabled children matched with 150 normal readers aged 6 to 11?years old were tested. They had to read 120 stimuli varied in lexicality, frequency, and length. The results in terms of reading accuracy as well as in reading times show that both groups were affected by lexicality and length effects. In both groups, length and lexicality effects were significantly modulated by school year being greater in early grades and later diminish in length and just the opposite in lexicality. However, the reading difficulties group was less accurate and slower than the control group across all school grades. Analyses of the error patterns showed that phonological errors, when the letter replacement leading to new nonwords, are the most common error type in both groups, although as grade rises, visual errors and lexicalizations increased more in the control group than the reading difficulties group. These findings suggest that Albanian normal children use both routes (lexical and sublexical) from the beginning of reading despite of the complete regularity of Albanian, while children with reading difficulties start using sublexical reading and the lexical reading takes more time to acquire, but finally both routes are functional. 相似文献

The relationships between phoneme categorisation, phonological processing, and reading performance were examined in Chinese‐English speaking children in an English‐speaking environment. Second language (L2, i.e., English) phonological processing but not phoneme categorisation was related to L2 reading. First language (L1) oral language skills were related to Chinese reading with L1 phonological processing being related to the Chinese reading task with a strong phonological component (pseudocharacter reading). L1 phoneme categorisation skill was not strongly related to L1 reading. These findings suggest that phonological processing is related to reading tasks with heavy phonological demands, such as reading in an alphabetic orthography or pseudocharacter reading in a nonalphabetic orthography. Exposure to L1 reading might influence processes used by Chinese‐speaking children in an English‐speaking environment. 相似文献
