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

We examined the instability of reading errors, that is whether a child reads the same word sometimes correctly and sometimes incorrectly, as a function of the complexity of context-sensitive spelling rules (vowel degemination and consonant gemination). Dutch bisyllabic words were read twice by typical readers in Grades 2 and 3, and reading-level matched poor readers. Grade 3 readers produced more unstable errors than Grade 2 readers. The poor readers did not differ from the typical readers in overall error instability. For typical readers, vowel degemination complicates word identification. For poor readers this effect was even stronger. Of the lexical and sublexical word characteristics, word frequency was the strongest predictor: The higher word frequency, the higher error instability. Word frequency, moreover, interacted with context-sensitive spelling rules in its effect on error instability. Error instability can be considered as an indicator of the transition from incompetence to reading competence. 相似文献

Cross-linguistic studies suggest that the orthographic system determines the reading performance of dyslexic children. In opaque orthographies, the fundamental feature of developmental dyslexia is difficulty in reading accuracy, whereas slower reading speed is more common in transparent orthographies. The aim of the current study was to examine the extent to which different variables of words affect reaction times and articulation times in developmental dyslexics. A group of 19 developmental dyslexics of different ages and an age-matched group of 19 children without reading disabilities completed a word naming task. The children were asked to read 100 nouns that differed in length, frequency, age of acquisition, imageability, and orthographic neighborhood. The stimuli were presented on a laptop computer, and the responses were recorded using DMDX software. We conducted analyses of mixed-effects models to determine which variables influenced reading times in dyslexic children. We found that word naming skills in dyslexic children are affected predominantly by length, while in non-dyslexics children the principal variable is the age of acquisition, a lexical variable. These findings suggest that Spanish-speaking developmental dyslexics use a sublexical procedure for reading words, which is reflected in slower speed when reading long words. In contrast, normal children use a lexical strategy, which is frequently observed in readers of opaque languages. 相似文献

The present study examined the construct and predictive validity of a dynamic test of decoding. In theory, a dynamic test provides a direct measure of potential for learning. In this study, children were taught 3 novel letters and how to blend the sounds of those into new words, then they were tested on different words comprising the 3 letters. The study followed 171 children from kindergarten to the end of Grade 1. The dynamic test was found to add significantly to the longitudinal prediction of word reading difficulties at the end of Grade 1 even after controlling for a wide range of standard predictors. The dynamic test correlated strongly with concurrent measures of early reading, letter knowledge, and phoneme awareness but less strongly with vocabulary and nonverbal intelligence. It is suggested that the dynamic test taps learning of sublexical units and processing essential for initial reading development. 相似文献

The aim of the present study was to examine the spelling development of Greek‐speaking children in the early school grades. Although Greek orthography is regular for reading, it is much less transparent as far as spelling is concerned. Spelling development was investigated using a word spelling task designed to explore the effects of word length, familiarity and spelling regularity. One hundred and fifty normally developing primary school children living in Cyprus took part in the study. Results suggest that the children employed both phonological and lexical strategies in spelling Greek words. Results indicated that sub‐lexical procedures were more marked for younger children, whereas lexical processing was employed more widely by older children. The findings are interpreted in terms of stage developmental models. 相似文献

The main aim of our study was to find out the effect of several lexical and sublexical variables (lexical category, lexical frequency, syllabic structure, and word length) in the acquisition of reading in a transparent language such as Spanish. The second goal of our study was the comparison of the effect of these variables in normal and poor Spanish readers. One hundred and forty children (aged between 6 and 12), twenty of whom were poor readers, were tested using a reading test of 306 items in which we balanced all the variables. The dependent variable was the percentage of correct responses in a decontextualized word reading test. Our results showed that all the above mentioned variables produced a significant effect on the number of errors made by the children. This pattern of results suggests no difference between the processes involved in the reading acquisition of Spanish and those implicated in deep orthographies such as English. Our results also showed no qualitative differences between normal and poor readers. The four variables studied showed the same behaviour in their effect on reading performance for both normal and poor readers, indicating that poor readers also use both the lexical and the phonological route. Our data suggest the universality of the dual route model, independent of the transparency or opaqueness of the different alphabetical languages. 相似文献

We investigated influences of non‐alphanumeric rapid naming on decoding skill growth for regularly and irregularly spelled English words. In a longitudinal study, 52 at‐risk and 69 not‐at‐risk readers were tracked from Grade 1 to Grade 3. Non‐alphanumeric rapid naming ability measured in Grade 1 accounted for unique variance in irregular word decoding in early Grade 2 – strong rapid naming was associated with strong irregular word decoding. An interaction between reading risk status and Grade 1 rapid naming indicated that the influence of Grade 1 rapid naming ability on growth in irregular word decoding was different for at‐risk than not‐at‐risk readers. Non‐alphanumeric rapid naming can have predictive validity as a marker for identifying specific difficulties in learning to read irregular words in at‐risk readers. Results indicate that rapid naming plays a general role in irregular word reading and a specific role in at‐risk readers' growth in irregular word decoding. 相似文献

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

In Greek orthography, stress position is marked with a diacritic. We investigated the developmental course of processing the stress diacritic in Grades 2 to 4. Ninety children read 108 pseudowords presented without or with a diacritic either in the same or in a different position relative to the source word. Half of the pseudowords resembled the words they were derived from. Results showed that lexical sources of stress assignment were active in Grade 2 and remained stronger than the diacritic through Grade 4. The effect of the diacritic increased more rapidly and approached the lexical effect with increasing grade. In a second experiment, 90 children read 54 words and 54 pseudowords. The pattern of results for words was similar to that for nonwords suggesting that findings regarding stress assignment using nonwords may generalize to word reading. Decoding of the diacritic does not appear to be the preferred option for developing readers. 相似文献

This study explores early stages of reading acquisition, specifically therelation of phoneme blending and letter recoding to individual differencesin word decoding. The hypothesis was that facility in letter recoding andaccuracy of phoneme blending are substantial components of word decodingin beginning readers but not for skilled reading and that reliance onphoneme-sized decoding of words would dissipate as reading proficiencyincreased. In four studies we examined the ability to recode letters, blendphonemes and decode words in four groups of Dutch children (early Grade1, N = 130, older Grade 1, N = 81, Grade 3, N = 54 and a group of children witha reading lag, N = 356). Phoneme blending was only related to the readingability of beginning Grade 1 children. By the end of Grade 1 ability to blendphonemes did not differentiate reading capacity, nor for older children inGrade 3 and reading disabled children. Letter recoding was related to worddecoding in all four studies, although the strength of that relation diddwindle as reading skill level increased. The results of the study appearconsistent with self teaching hypothesis and other theories that imply atransient role of explicit phonological recoding in word identification. 相似文献

The purpose of this study is to examine factors that influence students’ reading of derived words. Recent research suggests that the lexical quality of a derived word depends on the familiarity of the word, its morphemic constituents (i.e., base word and affixes), and the frequency with which the base word appears in other words (i.e., members of the same word family or family frequency). On the premise that better and more experienced readers have higher quality lexical representations, we explore the extent to which accuracy of reading derived words by 4th and 6th graders is related to measures of familiarity, including derived and base word frequencies, family size, average family frequency, and word length. The results of an exploratory factor analysis indicated that these measures formed two factors, one representing morphemic constitution and the second representing exposure to the word family; both factors accounted for significant variance in the students’ derived word reading. Comparisons of sets of derived words contrasted on familiarity properties showed that performance on derived words, overall, is better for 6th than 4th graders and for good than poor readers. On the measures of family frequency and family size, there were significant discrepancies between grade level and reading ability and frequency characteristics. These add support to the view that morphemic analysis and wide reading experience contribute to derived word reading. 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 direct, retention, and transfer effects of repeated word and pseudoword reading were studied in a pretest, training, posttest, retention design. First graders (48 good readers, 47 poor readers) read 25 CVC words and 25 CVC pseudowords in ten repeated word reading sessions, preceded and followed by a transfer task with a different set of items. Two weeks after training, trained items were assessed again in a retention test. Participants either received phonics feedback, in which each word was spelled out and repeated; word feedback, in which each word was repeated; or no feedback. During the training, both good and poor readers improved in accuracy and speed. The increase in speed was stronger for poor readers than for good readers. The good readers demonstrated a stronger increase for pseudowords than for words. This increase in speed was most prominent in the first four sessions. Two weeks after training, the levels of accuracy and speed were retained. Furthermore, transfer effects on speed were found for pseudowords in both groups of readers. Good readers performed most accurately during the training when they received no feedback while poor readers performed most accurately during the training with the help of phonics feedback. However, feedback did not differentiate for reading speed or for effects after the training. The effects of repeated word reading were found to be stronger for poor readers than for good readers. Moreover, these effects were found to be stronger for pseudowords than for words. This indicates that repeated word reading can be seen as an important trigger for the improvement of decoding skills. 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

Thai, a tonal language, has its own distinctive alphabetic orthography. The study investigates reading and spelling development
in Thai children, with an aim of examining the grain size that is predominantly used when reading and spelling. Furthermore,
word and nonword lists were developed to examine the acquisition of the complex system of vowels and tone rules in Thai. Reading
and spelling of words and nonwords were assessed in 60 Thai children ranging in age from 7 to 9 years 8 months from Grade(s)
1, 2, and 3. A lexicality effect was found for both reading and spelling. Spelling lagged behind reading in the Grade 1 children.
Development rapidly increased between the youngest Grade 1 children and the older Grade 2 and 3 children. For word reading
there were significantly more lexical errors than phonological errors. Beginning readers appear to predominantly use a larger
lexico-syllabic grain size to read Thai. 相似文献

AbstractThis study aims to identify the predictors of Chinese reading and literacy skills among Chinese school children in Taiwan. Participants recruited in the study were 182 Grade 1 elementary school students. First, data were collected on these students’ literacy skills, which comprised morphological awareness, orthography processing, visual perception skills, phonological awareness, and rapid automatised naming. In Grade 2, data were collected from these students on their word decoding skills, which comprised character recognition and reading fluency. Finally, in Grade 3, data were collected on the Chinese comprehension skills of the same students. A structural equation model examined the direct and indirect effects of students’ literacy skills at Grade 1 on their reading comprehension at Grade 3, with students’ word decoding at Grade 2 acting as a mediator. Results showed that reading comprehension of students at Grade 3 was predicted by their literacy skills at Grade 1. 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

Comparisons of the effects of typical and atypical typeface on reading performance among readers of different linguistic backgrounds may yield new insights into the psychology of word recognition. A total of 143 adults (i.e., 50 Chinese, 55 Koreans, 38 native English speakers) participated in the study that involved two computer-based naming tests. The tests presented words with letters that varied in size and shape in Experiment 1 and words containing scrambled letters in Experiment 2. Results from Experiment 1 showed that the interference effect of size and shape on word naming accuracy and latency was robust for all readers. Likewise, results from Experiment 2 showed a broad interference effect of scrambled letters on word naming; however, scrambled letters appeared less disruptive to word naming among Chinese readers compared to their Korean and native English speaking counterparts. Taken together, Chinese speakers were less efficient in recognizing atypical words at the sublexical level, but more efficient at the lexical level. 相似文献

Recent research has demonstrated that slight increases of inter-letter spacing have a positive impact on skilled readers' recognition of visually presented words. In the present study, we examined whether this effect generalises to young normal readers and readers with developmental dyslexia, and whether increased inter-letter spacing affects the reading times and comprehension of a short text. To that end, we conducted a series of lexical decision and continuous reading experiments in which words were presented with the default settings or with a small increase in inter-letter spacing. Increased spacing produced shorter word identification times not only with adult skilled readers (Experiment 1), but also with young normal readers (Grade 2 and Grade 4 children; Experiment 2) and, even to a larger degree, with readers with dyslexia (Experiments 3 and 4). These experiments suggest that slight increases in inter-letter spacing would improve the readability of texts aimed at children, especially those with dyslexia. 相似文献
