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

We investigated whether children who were learning to read simultaneously in English and French activate phonological representations from only the language in which they are reading or from both of their languages. Children in French Immersion programs in Grade 3 were asked to name aloud cognates, interlingual homographs, interlingual homophones, and matched control words. Half of the participants performed the task in English, their first oral language, and half performed the task in French. Control monolingual children in each language were also tested. In the French reading task, fewer errors were observed for cognates and interlingual homophones than for matched control words, whereas more errors were produced for interlingual homographs than matched controls. Only the inhibitory interlingual homograph effect was observed in the English reading task. These data provide evidence that phonological activation in bilinguals is not language selective. The locus of each of these effects in the bilingual word recognition system is discussed.  相似文献

The effect of phonology and semantics on word learning in 5- and 6-year-old children was explored. In Experiment 1, children learned to read words varying in spelling-sound consistency and imageability. Consistency affected performance on early trials, whereas imageability affected performance on later trials. Individual differences among children in phonemic awareness on the trained words were related to learning, and knowledge of a word's meaning predicted how well it was learned. In Experiment 2, phonological and semantic knowledge of nonwords was manipulated prior to word learning. Familiarization with a word's pronunciation facilitated word learning, but there was no additional benefit from being taught to associate a meaning with a nonword.

Young children were taught to name 12 single words, six in the presence of appropriate pictures (compound stimuli) and six in their absence (simple stimuli). There were two compound conditions: one in which the picture was a large line drawing above a small printed word (enhanced salience condition) and one in which it was a small line drawing below a large printed word (reduced salience condition); and two corresponding simple conditions of a large word alone (enhanced salience condition) and a small word alone (reduced salience condition). Each child experienced all four conditions with three different words in each condition in a series of randomly ordered learning and test trials, until each child achieved the criterion of three consecutive correct responses for each of the words in at least one of the conditions. Two experimental studies were completed with 16 children in each, and the percentage of correct responses was calculated for each presentation condition. Comparisons of the compound (picture) and simple (no‐picture) conditions showed that twice as many words were correctly recognised in the simple (no‐picture) conditions in both experiments. No reliable differences were detected between the different levels of salience, and it was concluded that prior association between the picture and the naming response to the picture ‘blocked’ the acquisition of a new association between the written word and the naming response to it.  相似文献

The current study examined several alternative explanations of the association between serial naming speed within fourth‐grade children by determining the extent to which the association between word reading and naming speed for letters and numbers is mediated by global processing speed, alphanumeric symbol processing efficiency and phonological processing ability. Children were given multiple measures of key constructs, i.e. word‐level reading, serial naming of both alphanumeric and non‐alphanumeric items, phonological processing ability, articulation rate and global processing speed. The robust association between alphanumeric naming speed and reading within fourth‐grade children was largely mediated by phonological processing ability. Markedly different patterns of results were observed for naming speed for letters and digits and naming speed for colours and pictures in children of this age. Relative to the latter, alphanumeric naming speed better assesses an underlying phonological processing ability that is common to word‐reading ability. We argue that item identification processes contribute little to individual differences in alphanumeric naming speed within relatively proficient readers and that the extent to which alphanumeric naming speed primarily reflects phonological processing is likely to vary with the level of overlearning of letters and numbers and their names.  相似文献

The acquisition of a reading vocabulary for abstract and concrete words was examined in 62 second-grade children. Words had been learned as part of a basal reader program or as part of outside reading. Word recognition speed and reading accuracy were examined for abstract and concrete words using lexical decision and word naming tasks. The size of the concreteness effect was similar for both processing tasks. In neither task did concreteness influence reaction times, but abstract words were read with less accuracy than concrete words in both tasks. Further, these concreteness effects in reading accuracy were larger for words that were part of a basal reading program than for words acquired during free reading. We conclude that word meaning influences the entry of words at a time when children are developing a sizeable reading vocabulary.  相似文献

The purpose of the experiments was to determine the automatic use of large or small word reading units in young readers in the absence of word decoding strategies. Picture-word Stroop interference was examined from four types of conflicting labels: (a) words containing both highly predictable grapheme–phoneme correspondence (GPC) units and highly consistent rime units (henceforth, Hi-GPC + Hi-Rime); (b) words with highly predictable GPC units and less consistent rime units (Hi-GPC + Lo-Rime); (c) words with low predictability GPC units and highly consistent rime units (Low GPC + High Rime); (d) nonwords that contained both highly predictable GPC and highly consistent rime units. Naming time for pictures containing these labels was compared against that for pictures with random letter strings or no labels. In Experiment 1, Stroop interference was examined in first, second, and third grade children to determine whether there was developmental change in the presence of rime or GPC interference. In Experiment 2, Stroop interference was examined as a function of relative reading skill in first grade children. In Experiment 3, Stroop interference in adults was compared to the use of rime or GPC pronunciation strategies for nonword reading. In all experiments, Stroop interference in picture naming was longer for pictures with highly predictable GPC unit labels than less predictable GPC unit labels. However, in Experiment 3, even though adults showed interference from predictable GPC units in the Stroop task, they always preferred rime pronunciation for ambiguous nonwords in the nonword reading task. It is argued that the current experiments provide evidence for a flexible units model. The results of this study were presented at the Cognitive Development Society meeting, November 2001, Virginia Beach, VA, and the American Educational Research Association meeting, April 2004, San Diego, California.  相似文献

An experiment is reported which investigates the perceptual span available to skilled readers in a single fixation. After adult readers had listened to an incomplete sentence they were presented tachistoscopically with a word which they were to name aloud. Congruency between sentence and word facilitated naming, but the presence of an unattended word in the right visual field confounded this relationship. If the unattended word was also congruent, then the naming response was further facilitated, but a congruent unattended word interfered with the naming of an incongruent attended word. This relationship did not hold for unattended words which were presented in the left visual field, and which did not appear to have been processed for meaning. An effect of an unattended word upon the naming of a fixated word suggests that skilled readers recognize the meanings of more words than are fixated. Skilled readers may use the meanings of words ahead of fixation to enrich their interpretation of the text, or use those words more simply as markers to guide future eye-movements to the location of the next useful fixation.  相似文献

Three experiments are reported that investigate the cognitive processes underlying contextual and isolated word reading. In Phase 1, undergraduate participants were exposed to 75 target words under three conditions. The participants generated 25 words from definitions, read 25 words in context and read 25 in isolation. In Phase 2, volunteers completed either an explicit recall task (Experiment 1), an implicit word stem completion task (Experiment 2) or both tasks (Experiment 3). Our findings provide converging evidence that contextual and isolated word reading elicit different patterns of cognitive processing. Specifically, Experiments 1–3 demonstrated that words read in context were remembered similarly to words generated from definitions: words from both conditions were recalled more frequently in the surprise memory task and selected less often to complete the word stems in the implicit memory task. The opposite pattern was noted for words read in isolation. Reading in context is discussed in terms of its greater reliance on semantic processing, whereas isolated word reading is discussed in relation to perceptually driven processes.  相似文献

In the current research the performance of children with and without reading disabilities was compared on a single word naming task. An analysis was carried out of the frequency and form of naming errors produced by the groups when naming real words and nonwords in a transparent orthography such as Spanish. A sample of 132 (45 normal readers, 87 reading disabled) Spanish children aged 9–10 years were selected, and an experiment was carried out to investigate if students with reading disabilities would have particular difficulties in naming words under conditions that require extensive phonological computation. While the children were performing the naming task, we recorded what they read to subsequently analyse the form, as well as the frequency, of naming errors as a function of lexicality, word frequency, word length and positional frequency of syllables. Disabled readers made more errors in nonwords, low frequency words and long nonwords. The findings support the hypothesis that poor phonological skills are a characteristic of reading disabled children.  相似文献

There is a consensus that dyslexia is on a continuum with normal reading skill and that dyslexics fall at the low end of the normal range in phonological skills. However, there is still substantial variability in phonological skill among dyslexic children. Recent studies have focused on the high end of the continuum of phonological skills in dyslexics, identifying a “surface” dyslexic, or “delayed” profile in which phonological skills are not out of line with other aspects of word recognition. The present study extended this work to a longitudinal context, and explored differences among subgroups of dyslexics on a battery of component reading skills. Third grade dyslexics (n=72) were classified into two subgroups, phonological dyslexics and delayed dyslexics, based on comparisons to younger normal readers at the same reading level (RL group). The children were tested at two points (in third and fourth grade). The results revealed that the classification of dyslexics produced reliable, stable, and valid groups. About 82 percent of the children remained in the same subgroup category when retested a year later. Phonological dyslexics were lower in phoneme awareness and expressive language. Delayed dyslexics tended to be slower at processing printed letters and words but not at rapid automatic naming of letters, and relied more heavily on phonological recoding in reading for meaning than did phonological dyslexics. A subset of the delayed dyslexics with the traditional “surface dyslexic” pattern (relatively high pseudoword and low exception word reading) was also identified. The surface subgroup resembled the RL group on most measures and was not very stable over one year. The results are discussed in light of current models of dyslexia and recent subgrouping schemes, including the Double-Deficit Hypothesis.  相似文献

Third and fifth grade children (average age 8.6and 10.6 years) and adult participants weretested with printed words of varying length ina new on-line identification task (theluminance increment paradigm, LIP) and aspeeded naming task. Effects of general length(length in letters, phonemes and syllables)were shown to decrease systematically with agein both tasks. Third grade children showedsubstantial effects of word length while theeffect practically disappeared in adults. Ingeneral, this developmental pattern was alsofound when separately examining effects ofphonological length (with length in lettersheld constant) and small unit length (withnumber of syllables held constant), althoughsome differences were observed in performancein the identification and the naming task. Thetwo tasks also showed different developmentalpatterns, with the greatest gain in performancearising between 3rd and 5th grade inthe naming task, and the largest improvementoccurring between 5th grade and adults inthe identification task. The results suggestthat the new luminance increment paradigm canbe usefully applied as an on-line measure ofprinted word perception in beginning readers.  相似文献

Nine- and twelve-year-old children named target words which were preceded by sentences ending in words having more than one meaning. Sentences biased the ambiguous word toward its dominant (more frequent) or subordinate (less frequent) meaning. Targets were related to the same meaning as that biased by the sentence, the other meaning, or were unrelated. Targets were presented 0, 300, or 700 ms following the sentence. For both ages, dominant sentences facilitated responses only to the contextually appropriate target. However, subordinate sentences led to facilitation of the appropriate meaning only for the younger group. Older children showed greater facilitation for the inappropriate (but more common) meaning. These results indicate that younger children are more sensitive to the sentence context in which an ambiguous word appears, while the processing of the older children is determined more by the relative frequencies of the words meanings.  相似文献

Recent research indicates that bilingual children are more proficient in resolving cognitive conflict than monolinguals. However, the replicability of such findings has been questioned, with poor control of participants' socioeconomic status (SES) as a possible confounding factor. Two experiments are reported here, in which the main attentional functions and pragmatic ability of 54 bilingual and 56 monolingual low‐SES children were assessed (Experiment 1: 6‐ to 12‐year‐olds; Experiment 2: 6‐ to 8‐year‐olds). A language‐switching task was also employed, to measure bilingual proficiency. Overall, the monolingual and bilingual groups did not differ significantly in any of the tasks employed, although the ability to resolve conflict was related to children's level of bilingual experience.  相似文献

This study aimed to determine whether the reading skills of third‐grade schoolchildren are associated with their preferences for semantic, phonological, and shape competitors (images or printed words) after being exposed to a spoken critical word. Two groups of children participated: skilled readers and less‐skilled readers. Through a language‐mediated visual search, children's fixations on the three competitors and a distractor were measured. When looking at images, both groups of readers preferred to look at the semantic competitor. When reading words, both groups showed a preference for the phonological competitor, but only skilled readers were sensitive to semantic information. These results suggest that early reading skills influence access to different types of representations in response to hearing a word, and they confirm the existence of a cascaded activation of information retrieval in childhood.  相似文献

This discussion is a review of experimental work designed to determine whether pictures have an effect upon the derivation of meaning from the text printed in children's reading materials. Many reading schemes emphasize the use of illustration, but for a number of different purposes ranging from the provision of a referent for a specific word, to the provision of' contextual support, and the generation of motivation for reading. Experimental studies of the interactions between pictures arid words in the cognitive system go some way to supporting three uses of illustration in (a) the provision of meanings against which the print may be compared, (b) in the development of an organized understanding of the meaning of the text, and (c) in the enhancement of subsequent recall. The danger of distraction arising from the pictures has also been investigated, and been found to lead to decoding errors in young children presented with one word at a time. An analysis of mutual interference effects between pairs of pictures and words leads to the conclusion that the cognitive representations of meanings arc organized in a semantic system common to pictures and words. Thus, any decoding errors due to interference effects are of more than local importance—they can affect comprehension and influence the stored representation.  相似文献

After third grade of elementary school, native Hebrew speakers in Israel gradually become expert in reading two kinds of writing systems: the one they start with that contains signs for every phoneme of the spoken language, and another, to which they are steadily introduced, beginning with the second grade, which omits most vowels, together with few consonantal distinctions. Earlier studies indicate that single voweled words are read faster than unvoweled words, particularly in a naming task. This study examined another possible contribution of vowel signs in reading Hebrew: Its effect on memory and comprehension. It was assumed that if subvocalization facilitates memory of words while reading, and if vowel signs facilitate phonological processing, as is perhaps the case in naming tasks, then vowelization may intensify the processing of the articulatory loop and this should improve memory and comprehension. Our first two experiments assessed the contribution of vowel signs to the memory of word lists in either recognition memory or word recall tasks. The third experiment examined the contribution of vowel signs to the reading of connected texts. We found that vowel signs speeded up recognition memory of words in third graders, and improved the recall of words printed in the context of mixed lists in sixth graders. We also found that vowelization improved memory and comprehension of some prose texts.  相似文献
