This study investigated the effects of the Arabic root in the visual word recognition process among young readers in order to explore its role in reading acquisition and its development within the structure of the Arabic mental lexicon. We examined cross-modal priming of words that were derived from the same root of the target (/murattabun/-/tarti:bun/well ordered–order) relative to prime words that included three letters of the target but not root letters (/tura:bun/-/tarti:bun/soil-order) in two elementary-school age groups: second grade and fifth grade. The results showed facilitation in lexical decisions about target words, suggesting that the root is a lexical unit that plays a crucial role in the processing and representation of Arabic from the early stages of written language acquisition. This issue may stem from the morpho-orthographic nature of the written Arabic word and/or from the semantic information conveyed from the roots’ morpheme.  相似文献

The study examined children and adolescents’ ability to improve root spelling in Hebrew words by paying attention to phonological, semantic and orthographic properties of priming roots. One hundred and fifty 8, 9, 10, 11 and 15-year olds were administered two spelling tests in Hebrew. The same 40 target words were used in both tests, each word containing a root with at least one homophonous letter. Target words were matched one-to-one with 40 priming words containing the same root. The pool of prime-target word pairs was classified into two major groups:Words containing genuine root primes, and words containing false root primes. In the first test, participants had to spell the 40 target words. In the second test they had to spell the same words, each primed by its written genuine or false match. Results showed that unprimed spelling improved with age. Priming – both genuine and false – improved spelling performance significantly, especially in younger grades, but genuine priming was more effective. Spellers were able to overcome phonological opacity in root primes and to take root semantics into account. This finding testifies to the robustness of the root as a unified morphological entity in Hebrew and to children’s ability to make use of their knowledge of lexical and morphological organization in learning to spell.We thank Dominiek Sandra, Harald Baayen and an anonymous reviewer for their important and constructive comments on an earlier version of this paper.  相似文献

Korean has visually salient syllable units that are often mapped onto either prefixes or suffixes in derived words. In addition, prefixed and suffixed words may be processed differently given a left-to-right parsing procedure and the need to resolve morphemic ambiguity in prefixes in Korean. To test this hypothesis, four experiments using the masked priming lexical decision paradigm were conducted. Results showed that suffixed primes facilitated responses to their stem targets regardless of the lexicality or interpretability of the primes. In contrast, prefixed primes had a significant effect only when they were real words, and not when they were either interpretable or noninterpretable prefixed pseudowords. These results suggest that there may be two different processing mechanisms for derived words in Korean. One is prelexical morphological decomposition for suffixed words, and the other is the supralexical analysis for prefixed words where decomposition occurs only after the whole word has been accessed.  相似文献

Previous research has suggested that children in the early grades of primary school do not have much awareness of morphemes. In this study, a priming paradigm was used to try to detect early signs of morphological representation of stems through a spelling task presented to Portuguese children (N = 805; age range 6–9 years). Primes shared the stem with the targets and contained well-articulated, stressed vowels; the stems of the target words and pseudo-words contained non-stressed schwa vowels, which typically result in spelling difficulties. If priming proved effective, the well-articulated vowels in the prime should result in an improvement in the spelling of the schwa vowels. Primes were presented in two conditions: in only-oral or in oral-plus-written form. Effectiveness of priming was assessed by comparison with a no-priming condition. For both words and pseudowords, there was a significant interaction between priming effects and grade. No priming effects were detected in 6- and 7-year-old children; oral-plus-written priming produced higher rates of correct vowel spelling for 8- and 9-year-olds; only-oral priming was effective in improving the vowel spelling of 9-year-olds. Thus older children can use morphological information under priming conditions when the prime and the target are not phonologically transparent but there is no evidence to suggest that younger children do so.  相似文献

This study examined the importance of morphological awareness in Korean–English biliteracy acquisition. English is an opaque orthographic system, in which letters and sounds have indirect correspondences. Korean Hangul, on the other hand, is a transparent orthographic system where there are direct letter-sound correspondences. Sixty-five children from Grades 2 to 4 were tested on a set of comparable Korean and English tasks tapping into oral vocabulary, phonemic awareness, morphological awareness, real word reading, and passage reading comprehension. Results showed that morphological awareness explained a significant amount of variance in word reading and reading comprehension within both Korean Hangul and English, suggesting that morphological awareness is important not only in an opaque orthography but also in a transparent orthography. Furthermore, morphological awareness in one language uniquely predicted a significant amount of variance in reading real words in the other language, suggesting that morphological awareness facilitates word reading across different orthographies.  相似文献

The paper reported an exploratory study that tested (a) the relationship between phonological and morphological awareness in English (L1)–Arabic (L2) bilingual children in Canada (N = 43), and (b) the relevance of these skills to word and pseudoword reading accuracy, and to complex word reading fluency. The results showed a significant correlation between phonological awareness in English and in Arabic. However, morphological awareness in the two languages was not correlated. Phonological awareness predicted reading cross-linguistically, but only Arabic morphological awareness predicted word reading in English. Moreover, while both phonological and morphological awareness in English predicted independent unique variance in English word reading, only phonological awareness in Arabic predicted Arabic word reading. Complex-word reading fluency was predicted by morphological awareness within both languages. Similarly, in both languages, phonological awareness was the single factor predicting pseudoword decoding accuracy. The results are discussed in terms of cross-linguistic differences between English and Arabic in orthographic depth and in morphological structure and transparency.  相似文献

This study examined three processes crucial to reading comprehension (semantic access, integration, and inhibition) to identify causes of comprehension impairment. Poor comprehenders were compared to chronological-age controls and vocabulary-age (VA) controls. When listening to homonym primes (“bank”) versus unrelated primes, controls were faster to name pictures related to dominant (money) and subordinate (river) meanings at 250 ms interstimulus interval (ISI) but only showed dominant priming at 1,000 ms ISI, whereas poor comprehenders only showed dominant priming. When listening to subordinately biased sentences ending in homonyms (“John fished from the bank”) versus control sentences, all groups showed priming when naming subordinate (appropriate) pictures at 250 ms ISI: VA controls and poor comprehenders also showed priming when naming dominant (inappropriate) pictures. At 1,000 ms ISI, controls showed appropriate priming, whereas poor comprehenders only showed inappropriate priming. These findings suggest that poor comprehenders have difficulties accessing subordinate word meanings, which can manifest as a failure to inhibit irrelevant information.  相似文献

ABSTRACT

We investigated how and when French children in Grades 1–5 acquire orthographic representations for silent letters and double consonants. Linear mixed-effects modeling analyses on the spelling accuracy scores obtained for 2,519 French words were used to test our predictions. As predicted, the presence of a silent letter or double consonant had a unique detrimental effect on spelling accuracy that was not captured by the inconsistency and complexity generated by these letters, and this effect tended to decrease across grades. Important to note, exposure to more frequent silent-letter endings or double consonants had a facilitative effect over and above consistency that did not seem to change across grades. These findings suggest that children implicitly acquire representations for letters with no phonological value. The results obtained for other predictors also suggest a shift from a lower level, phoneme-based processing to a higher level processing at the word and rime levels as children acquire more reading experience.  相似文献

Morphological awareness and learning to read Chinese   总被引：1，自引：0，他引：1  
This study investigated the nature of morphological awareness and its relation to learning to read Chinese characters among 46 Chinese-speaking preschool children. The children took a morphological awareness task, which varied in semantic transparency and morpheme position. Children’s vocabulary knowledge and extant character reading ability were measured. Additionally, a character learning task was administered. Results showed that children’s performances on morphological awareness were affected by semantic transparency but not by morpheme position. Morphological awareness was related to vocabulary knowledge when partialling out character reading ability but not to character reading ability after partialling out vocabulary knowledge. The results of the character learning task further revealed that morphological awareness was related to character identification in the words that were just taught but not to character identification in the words that were not taught or in pseudowords. The relation between morphological awareness and character identification ceased to be significant when partialling out the variance in children’s prior knowledge of the characters to be learnt. Taken together, the findings suggested that vocabulary knowledge may play a more important role than reading ability in the initial development of morphological awareness and that the facilitative effect of morphological knowledge in reading does not seem to be significant in the very initial stages of reading acquisition.  相似文献

The automatic letter-sound integration hypothesis proposes that the decoding difficulties seen in dyslexia arise from a specific deficit in establishing automatic letter-sound associations. We report the findings of 2 studies in which we used a priming task to assess automatic letter-sound integration. In Study 1, children between 5 and 7 years of age were faster to respond to a speech-sound when primed by a congruent letter, indicating that automatic activation of sounds by letters emerges relatively early in reading development. However, there was no evidence of a relationship between variations in the speed of activating sounds by letters and reading skill in this large unselected sample. In Study 2, children with dyslexia demonstrated automatic activation of sounds by letters, though they performed slowly overall. Our findings do not support the theory that a deficit in automatic letter-sound integration is an important cause of reading difficulties but do provide further evidence for the importance of phonological skills for learning to read.  相似文献

Most sinograms (i.e., Chinese characters) are phonograms (phonetic compounds). A phonogram is composed of a semantic radical and a phonetic radical, with the former usually implying the meaning of the phonogram, and the latter providing cues to its pronunciation. This study focused on the sub-lexical processing of semantic radicals which are themselves free standing sinograms. Two primed naming experiments were carried out to examine whether the meanings and pronunciations of the semantic radicals embedded in phonograms were activated or not during sinogram recognition. In Experiment 1, semantically opaque phonograms were used as primes. We observed facilitatory priming effects for targets which were semantically related to the semantic radicals embedded in primes, but not to the primes themselves. These effects were present for low-frequency primes, but not for high-frequency primes. Experiment 2 used only low-frequency phonograms as primes. We observed facilitatory priming effects for targets which were homophones of the semantic radicals embedded in primes, but not of the primes themselves. These results suggest that sub-lexical semantic and phonological information of semantic radicals are activated, and that the activation processes are modulated by the lexical frequency of the host phonograms. Our study shows that sub-lexical processing of semantic radicals is similar to that of phonetic radicals, indicating no fundamental difference between sub-lexical processing of semantic and phonetic radicals, supporting the view that a radical has a unique representation irrespective of its function in the orthographic system of Taft’s model.  相似文献

Abstract. This study focuses on the source of reading problems of English as a second language learners at the high school level. The results indicate that while reading comprehension is impacted by level of receptive vocabulary knowledge, the ability to select and implement word-appropriate lexical inferencing strategies can compensate for low receptive vocabularies in relation to the demands of the text. The ability to make this selection, however, implies not only sensitivity to word structure, but also the ability to implement morphological analysis in conjunction with contextual guessing, where appropriate. These findings suggest that the development of English as a second language reading proficiency may be accelerated by acquisition of the meanings of the most productive affixes of English in conjunction with instruction in the principles of morphological analysis.  相似文献

Four groups of Dutch readers, (a) beginners, second grade elementary school students with 2 years of reading experience, (b) advanced readers, sixth grade elementary school students with 6 years of reading experience, (c) expert readers, university students with 14 years of reading experience, and (d) poor readers, aged 13 years with 2 years of delay in reading skill, were presented with short stories followed by multiple-choice text comprehension questions. Participants were asked to read the stories for meaning and to circle the letter t whenever it occurred in the text. Five types of detection locations were defined: (1) verb suffix, (2) noun final, (3) intra word, second letter, (4) intra word, prefinal letter, and (5) definite article, final t. Differential detection patterns as a function of reading development were obtained. Beginning readers did not differ in detecting the final t in verbs and nouns, whereas expert readers showed a strong attentional bias to verb suffixes as compared with noun endings. Expert readers missed more intra word letters. In all groups prefinal letters were detected better than second letters in words, thus suggesting a general attentional bias for orthographic information in the second part of Dutch words. The t in the definite article was missed most often in all groups, which suggests sensitivity to word frequency at early stages in reading development. Poor readers did not show differential performance patterns as compared to the other reading groups. The overall developmental pattern can be characterized as a shift from attention for single letter information to attention for more complex morphological information in text.

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

Repetition priming was used to examine whether children with dyslexia bias a lexical–semantic pathway when reading words aloud. For the dyslexic group (n = 18, age 9.4–11.8 years), but not for age‐matched controls (n = 18, age 9.2–12.4 years), reaction times when naming pictures were faster after naming the corresponding word. A reading age‐matched control group (n = 24, age 6.8–8.9 years) showed similar priming effects to the children with dyslexia. The magnitude of repetition priming was greater for children with dyslexia with poor nonword reading and slower picture naming. Assuming repetition priming of picture naming is contingent on accessing lexical phonology via semantics, the results suggest less‐skilled normal and disordered readers show a stronger bias towards a lexical– semantic pathway during word reading than skilled readers, and the severity of the phonological representations deficit modulates the strength of that bias in children with dyslexia.  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

We describe the complex pattern of spared and impaired performance observed in a neurologically impaired subject on a number of letter processing tasks including: written letter naming, alphabetization, matching across typecase and font, oral and written spelling to dictation, and across-case letter priming. The observed dissociation in performance between the naming of written letters and the naming of letters in oral spelling as well as the dissociation between oral spelling and written spelling are shown to support a model of letter processing in which a distinction is drawn between visuo-spatial and abstract levels of letter representation. We also describe symmetrical deficits in the reading and writing of letters. These can be understood: in reading, as the result of an impairment to the processes which mediate the conversion of visuo-spatial letter representations to abstract representations, and in writing, as a deficit to the processes which negotiate the apparently reverse operation. This finding is interpreted within the context of the notions of neural and functional proximity and we raise the possibility that processes which perform distinct computations may, nonetheless, share certain computational resources.Requests for offprints should be addressed to Brenda Rapp or Alfonso Caramazza.

Morphology is one of the organizing principles of the mental lexicon. It is especially important in Hebrew, where word structure expresses a rich array of semantic notions. This study investigated the ability of Hebrew-speaking children to solve written morphological analogies by reading and completing two sets of real and invented root- and pattern-related nouns using a closed set of responses. In the first experiment, 152 gradeschoolers (2nd–6th grade) were administered an analogy task with real words, where they had to read written stimuli and elicit root and pattern components from them. In the second experiment, 148 gradeschoolers were administered a similar reading task with pseudowords. In both experiments, the results clearly indicate an early and robust ability of Hebrew-speaking children to perform morphological analogies using both roots and patterns. Most errors involved the root morpheme rather than the pattern morpheme, but pseudowords elicited more pattern errors. These results are discussed in view of models of morphological processing and morpho-lexical development in Hebrew.  相似文献

Two correlational studies from the same data set demonstrated the distinctiveness of character and word reading for Chinese reading development among 337 Hong Kong Chinese children in grades 1–3. Study 1 examined the cognitive-linguistic correlates of single-character reading and two-character word reading. Rapid automatized naming, morphological awareness and visual-orthographic skill independently explained variance in both character and word reading beyond age, grade, nonverbal IQ and vocabulary knowledge. Importantly, rapid automatized naming and morphological awareness additionally explained variance in word reading even after statistically controlling for character reading; there were no such unique correlates for character reading beyond word reading. Study 2 investigated the roles of character and word reading in reading comprehension. Both were individually significantly associated with reading comprehension even when a multifaceted measure of language comprehension was statistically controlled. Moreover, character reading and language comprehension significantly explained variance in reading comprehension through word reading; word reading and language comprehension uniquely contributed to reading comprehension in the model. Results suggest that character and word reading likely reflect slightly different processes in Chinese literacy: Theoretically, these results underscore the importance of models of reading that integrate unique features of Chinese. Practically, these results suggest that character and word reading may depend on different cognitive-linguistic processes which can be cultivated when teaching them, separately or together.  相似文献

The present study aimed to investigate the development of automatic phonological processes involved in visual word recognition during reading acquisition in French. A visual masked priming lexical decision experiment was carried out with third, fifth graders and adult skilled readers. Three different types of partial overlap between the prime and the target were contrasted: orthographic and phonological overlap (O+P+; ren-RENDRE [give] pronounced /?ɑ?/-/?ɑ?d?/ respectively), orthographic overlap (O+P?; re-RENDRE pronounced /??/-/?ɑ?d?/ respectively), or without orthographic and phonological overlap with the beginning of the target, namely unrelated (UR; pi-RENDRE pronounced /pi/-/?ɑ?d?/, respectively). The number of letters was controlled throughout the priming conditions. The results showed an interaction between grade and priming condition in children. In third graders, the results displayed a masked phonological priming effect (the O+P+ condition was compared to the O+P? condition) but not a masked orthographic priming effect (the O+P? condition was compared to the UR condition). On the contrary, in fifth graders, the results showed a masked orthographic priming effect but not a masked phonological priming effect. Adult skilled readers displayed the same pattern as fifth graders. These results are interpreted in the multiple-route model of reading development.  相似文献
