We report two experiments that investigated whether phonological and/or orthographic shifts in a base word interfere with morphological processing by French 3rd, 4th, and 5th graders and adults (as a control group) along the time course of visual word recognition. In both experiments, prime-target pairs shared four possible relationships: morphological without modification (nuageux-NUAGE), morphological with phonological modification (bergerie-BERGER), morphological with phonological and orthographic modifications (soigneux-SOIN), and orthographic control (fourmi-FOUR). In Experiment 1 (60-ms prime duration), priming effects were only significant in the morphological condition without modification in children but in the three morphological conditions in adults. In Experiment 2 (250-ms prime duration) priming effects were significant in all three morphological conditions in each group, independently of form shifts. These results indicate that allomorphic variation does allow for the lexical activation of base words only in the later stages of word recognition in children, whereas this activation is automatic in adults.  相似文献

The present study used a mediated priming paradigm to examine whether developmental differences exist in the integration of semantic information with orthographic and phonological information during visual word recognition. In Experiment 1, we found that the integration of semantics with phonology and orthography differed among third‐grade, sixth‐grade and college students: orthographically based mediated inhibition effects were found in third‐grade children, whereas phonologically based mediated inhibition effects were found in sixth‐grade children and college students. A second experiment was performed with adults to test the hypothesis that the orthographically based mediated inhibition effect observed with young children was due to deficits in orthographic processing. When stimulus quality was manipulated within the mediated priming paradigm, orthographically based mediated inhibition effects were found when targets were dim, whereas phonologically based mediated inhibition effects were found when targets were bright. Taken together, these results suggest that the allocation of activation during reading may depend on the processing demands of the word recognition system.  相似文献

This study examines the effects of semantic and phonetic radicals on Chinese character decoding by high-intermediate level Chinese as a foreign language (CFL) learners. The results of the study suggest that the CFL learners tested have a well-developed semantic pathway to recognition; however, their phonological pathway is not yet a reliable means of character identification. Semantic radicals that correctly pertain to character meaning facilitated reaction time in semantic categorization tasks, while radicals that had no immediately interpretable relation to character meaning had a strong inhibitory effect. The relative accuracy of phonetic radicals (for predicting the whole-character’s pronunciation) did not measurably improve homonym recognition. In a lexical decision task (Experiment 3), the subjects were significantly slower in identifying pseudo-characters when the phonological component was blurred, indicating that, despite having unreliable phonological pathways to character recognition, the subjects were still using phonological radical analysis as their default recognition strategy; however, the author argues that the radical is likely being used for orthographic disambiguation more than for phonological properties.  相似文献

The quality of implicit morphological knowledge in adult Hebrew readers with developmental dyslexia was investigated. The priming paradigm was used to examine whether these adults extract and represent morphemic units similarly to normal readers during online word recognition. The group with dyslexia as a whole did not exhibit priming with visual presentation as opposed to both age- and reading-level controls. Priming was absent when the prime and target words shared a morpheme and even when the prime and the target were identical. Only the students with phonological dyslexia, who exhibited relatively good performance in the orthographic judgment task, exhibited repetition priming but not morphological priming. Strong repetition and morphological priming effects were found for participants with dyslexia when the stimuli were auditory. The implications of the dissociation between visual and auditory priming for the locus of the deficit in morphological processing during word recognition are discussed.  相似文献

The effects of semantic and phonetic radicals on Chinese character decoding were examined. Our results suggest that semantic and phonetic radicals are each available for access when a corresponding task emphasizes one or the other kind of radical. But in a more neutral lexical recognition task, the semantic radical is more informative. Semantic radicals that correctly pertain to character meaning facilitated reaction time in semantic categorization tasks (Experiment #1), while radicals that had no immediately interpretable relation to character meaning had a strong inhibitory effect. Likewise, phonetic radicals that accurately indicated a character’s pronunciation facilitated a homonym recognition task (Experiment #2), whereas phonetic radicals that differed significantly in pronunciation from their character inhibited homonym recognition. In a lexical decision task (Experiment #3) where each character had either a blurred semantic radical or a blurred phonetic radical, the characters with a blurred semantic radical elicited a significantly higher error rate and a trend for longer response times. These results are interpreted to indicate that while educated native Chinese speakers have full use of both semantic and phonetic paths to character decoding, there is a slight predisposition to semantic decoding strategies over phonetic ones indicating that the semantic path is the default means of character recognition.  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

Two experiments were conducted to investigate the time course of semantic and phonological access in naming kanji and kana words. Japanese adults quickly named single words written in kanji and the same words written in kana in one session, and translated them into English in another session. In both experiments using nouns (Experiment 1) and verbs (Experiment 2), words were named faster in kana than in kanji but were translated faster in kanji than in kana. These findings were interpreted to suggest that kana words are closer to phonology while kanji words are closer to meaning. The optimum solutions obtained by the simplex method showed that semantic access takes place 10 to 19 msec earlier in kanji words than in kana words, whereas phonological access takes place 27 to 31 msec earlier in kana words than in kanji words. A possible difference between kanji nouns and verbs is briefly discussed in terms of phonological access time.  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

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 acquisition of the rabbit’s nictitating membrane response to a tone + light compound and its components was examined as a function of the CS-US interval (Experiment 1) and CS duration (Experiment 2). In Experiment 1, responding to the compound attained high levels in all groups, but responding on component test trials declined to low levels as the CS-US interval increased across values of 300, 800, and 1,300 msec. Further disparities between the compound and components appeared when the animals were shifted to a positive patterning schedule. In Experiment 2, disparities between the compound and components increased as the duration of the CS was increased across values of 50, 200, and 800 msec within a fixed CS-US interval of 800 msec. The results are discussed with respect to distributive processes, configuration, and speed-accuracy tradeoffs.  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

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

The present study tracked the time course of the syllable frequency effect in French visual word recognition, by varying the strength of spreading activation between letters and phonological syllables. The frequency of phonological first syllables and the frequency of orthographic first syllables were conjointly manipulated in two lexical decision tasks. In Experiment 1, word parsing into syllable units was supported by orthographic redundancy. No interaction between orthographic and phonological syllable frequency was found. In Experiment 2, word parsing into syllables was not marked by orthographic redundancy. Results showed an interaction between orthographic and phonological syllable frequency: the syllable frequency effect was inhibitory when orthographic syllable frequency was high, whereas it was facilitatory when orthographic syllable frequency was low. Decreasing the strength of syllable activation (i.e., with orthographic syllables of low frequency and ambiguous syllable boundaries) prevented the activation of lexical competitors before target word recognition, leading to a facilitatory effect of syllable frequency. The present study provides evidence that the net effect of syllable frequency is strongly related to its time course, and that the strength of syllable activation, which depends on orthographic properties, determines the direction of the net effect.  相似文献

Semantic knowledge accumulates through explicit means and productive processes (e.g., analogy). These means work in concert when information explicitly acquired in separate episodes is integrated, and the integrated representation is used to self-derive new knowledge. We tested whether (a) self-derivation through memory integration extends beyond general information to science content, (b) self-derived information is retained, and (c) details of explicit learning episodes are retained. Testing was in second-grade classrooms (children 7–9 years). Children self-derived new knowledge; performance did not differ for general knowledge (Experiment 1) and science curriculum facts (Experiment 2). In Experiment 1, children retained self-derived knowledge over one week. In Experiment 2, children remembered details of the learning episodes that gave rise to self-derived knowledge; performance suggests that memory integration is dependent on explicit prompts. The findings support nomination of self-derivation through memory integration as a model for accumulation of semantic knowledge and inform the processes involved.  相似文献

Evidence of phonological awareness levels usually comes from English-speaking children. The evidence in Spanish is scarce. The present study examined the phonological awareness of syllables, onsets–rimes, and phonemes, extending the Treiman and Zukowski (1991) results to preliterate and literate Spanish-speaking children. The sample comprised preschoolers, kindergarteners and first-graders. Children found syllables easier than onset–rime units, and onset–rime units easier than phoneme units (Experiments 1 and 2). Preliterate children found ending units easier than beginning units. However, literate children were best at initial linguistic units, particularly initial syllables. Results on the phonological awareness task and on the masked priming lexical decision task support that the phonological awareness development is sensitive to the orthographic units used by children from the time they begin to read (Experiment 3). For all children, initial continuant consonants were easier than stop consonants.  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 present study examined whether Japanesereaders activate phonological information whenreading kanji compound words and sentences andif so, how they do it. Experiment 1 usedtwo-kanji compound words in a lexical decisiontask to study phonological processing at thelexical level. When nonwords werepseudo-homophones (/roR hi/ in placeof the real word /roR hi/), reactiontimes were longer and more errors occurred thanwith nonwords in the control group(/saku hi/). Experiment 2required participants to detect misspellings(i.e., incorrect kanji combinations) oftwo-kanji compound stimuli embedded insentences. In the detection task of misspelledkanji, no homophonic effect was apparent. Experiment 3 used a semantic decision task. Included in this task were semantically similarbut incorrect kanji compound words used asfillers in sentences (e.g.,meaning `The building you can see over there was facilitated by my friend' instead of designed) as well as the sentences used inExperiment 2. Results from Experiment 3indicated that participants could reject asentence as incorrect more quickly whenpseudo-homophones were embedded in thesentences rather than nonwords. These resultssuggest that readers activate phonologicalinformation of two-kanji compound words whenreading for comprehension but not for simpleproofreading.  相似文献

Five experiments were conducted to examine the effects of cognitive load management using explanatory notes in reading passages for readers with different levels of expertise. Experiment 1 found that explanatory notes improved 5th-grade, first-language learners' comprehension (high-level processing) but not vocabulary learning (low-level processing). Experiment 2 found that vocabulary definitions integrated within a passage (integrated format) enhanced 5th graders' comprehension compared to a separate vocabulary list (separated format) but reduced vocabulary learning. Experiment 3, using adult readers, found that an integrated format reduced comprehension but enhanced vocabulary learning. Experiment 4 used low-ability 8th-grade learners of English as a second language (ESL) and found an effect similar to the 5th graders in Experiment 2. Experiment 5 showed that the effect for high-ability ESL learners was similar to the adults in Experiment 3. We argue that the efficiency of instruction depends on the extent to which it imposes an extraneous cognitive load. The same presentation format may facilitate performance or interfere with performance either through split-attention or redundancy effects, depending on learners' expertise.  相似文献

The present study investigated proximal and distal predictors of reading comprehension by including latent factors such as alphabet knowledge, phonological awareness, semantic knowledge, word reading, oral reading fluency, and reading comprehension. The sample consisted of 79 five-year-old Korean-monolingual children who were assessed at the end of the school year. The results showed that alphabet knowledge, phonological awareness, and semantic knowledge latent variables were all positively and highly related to word-reading skills, but phonological awareness made a unique contribution above and beyond alphabet knowledge and semantic knowledge. Word reading was highly related to oral reading fluency and directly related to reading comprehension. Oral reading fluency, although a separate construct from word reading accuracy, was not uniquely related to reading comprehension after accounting for the effects of word reading and semantic knowledge. Semantic knowledge was fairly strongly and uniquely related to reading comprehension.  相似文献
