The development of the concept of word in readers and nonreaders was investigated. Five reader and nonreader male students from four age groups (6.5–7.5; 7.6–8.5; 8.6–9.5; 9.6–10.5) were tested using the procedures developed by J. Downing and P. Oliver (Reading Research Quarterly, 1973–1974, 9, 581–586). Results from an analysis of variance indicated significant effects for reading levels (p < .001), age (p < .05), stimuli (p < .01), and a significant interaction between reading level and stimulus class (p < .05). Evidence indicates nonreaders may be confused about the differences between a short word and phonemes, syllables, sentences, and long words.  相似文献

The purpose of this study was (1) to examine the causal effects of READ 180, a mixed-methods literacy intervention, on measures of word reading efficiency, reading comprehension and vocabulary, and oral reading fluency and (2) to examine whether print exposure among children in the experimental condition explained variance in posttest reading scores. A total of 294 children in Grades 4–6 were randomly assigned to READ 180 or a district after-school program. Both programs were implemented 4 days per week over 23 weeks. Children in the READ 180 intervention participated in three 20-min literacy activities, including (1) individualized computer-assisted reading instruction with videos, leveled text, and word study activities, (2) independent and modeled reading practice with leveled books, and (3) teacher-directed reading lessons tailored to the reading level of children in small groups. Children in the district after-school program participated in a 60-min program in which teachers were able to select from 16 different enrichment activities that were designed to improve student attendance. There was no significant difference between children in READ 180 and the district after-school program on norm-referenced measures of word reading efficiency, reading comprehension, and vocabulary. Although READ 180 had a positive impact on oral reading fluency and attendance, these effects were restricted to children in Grade 4. Print exposure, as measured by the number of words children read on the READ 180 computer lessons, explained 4% of the variance in vocabulary and 2% of the variance in word reading efficiency after all pretest reading scores were partialed out.  相似文献

This paper used meta-analysis to synthesize the relation between visual skills and Chinese reading acquisition based on the empirical results from 34 studies published from 1991 to 2011. We obtained 234 correlation coefficients from 64 independent samples, with a total of 5,395 participants. The meta-analysis revealed that visual skills as a global construct had a medium correlation effect size (r?=?0.32) associated with Chinese reading acquisition. The various visual processing skills differed in their relation to Chinese reading acquisition in different stages. Visual perception, speed of processing visual information, and pure visual memory had low-to-moderate correlations with Chinese reading acquisition in the lower grades (i.e., below second grade), whereas these relations did not retain their magnitude for children in the higher grades (i.e., second through sixth grades). By contrast, visual–verbal association skill was found to account for 34 and 41 % of the variance in children’s Chinese reading acquisition in both lower and higher grade levels, respectively. Greater attention to this construct can significantly benefit reading research and instructional practice. No regional differences between studies in Mainland China and Hong Kong were found in the meta-analysis.  相似文献

The visual deficit hypothesis of development dyslexia has largely been abandoned because many of the phenomena that initially motivated it could not be replicated under controlled experimental conditions, while phonological processing deficits were found to provide a better explanation for the replicable phenomena. Nevertheless, many teachers and special educators continue to subscribe to the hypothesis that deficits of visual perception are a major cause of reading failure in dyslexia. As part of a larger family study, we reexamined the questions (1) whether probands and affected relatives in dyslexia families reverse easily confused letters more frequently under experimental conditions than normal readers from the same families, and (2) whether they show unusual facility in reading geometrically transformed text. The findings indicated that young dyslexia students reverse easily confused letters more often than normal readers. Reading group differences of letter reversal were significant in children from 7–10 years but not thereafter; and virtually no subject reversed letters when spelling whole words. Furthermore, dyslexic persons in every age group from 7–60 years actually took longer than normal readers to decode geometrically transformed text; and the time to decode transformed texts increased progressively with age after adolescence in both dyslexic persons and normal readers. Thus, reading group differences in decoding easily confused letters and reading geometrically transformed text do not support the visual deficit hypothesis and probably do not help to clarify the etiology of developmental dyslexia.  相似文献

This study investigated the effects of variations in graphic elements that account for differences in speed and accuracy between reading text aloud from paper versus laptop computer. Variations in accurate reading-aloud performance are attributable to individual differences in the visual accessibility of information due to (1) the experimental manipulations of the independent variables, (2) the subjects' prior exposure to print within the culture, and (3) the educational attainment of the subject. A non-representative sample of 48 female survey interviewers (ages 38–72) were employed in the conduct of this study. Survey interviewers were selected because they gather information using laptop computers; the quality of the survey information collected may be directly associated with the legibility of computerized text on reader performance. Subjects completed a prior exposure to print questionnaire (Stanovich & West 1989) and a demographic data form (IDIQ). Repeated-measures analyses of variance were employed to examine individual differences in the speed and accuracy of reading-aloud performance for twenty-four conditions varying the levels of independent variables including: (1) Font (Times Roman, Helvetica, and Courier), (2) Justification (fully- justified versus left-justified), (3) Leading (single-spaced versus double-spaced), and (4) Mode of Presentation (paper versus laptop computer). Linear regression analyses found subjects' prior exposure to print significantly and positively related to predicting speed and miscue performance. The subjects' educational attainment significantly predicted miscue performance. Subjects' ages were not significantly related to performance. Results of this study inform computer programmers and designers who are responsible for developing standards and guidelines for legible computerized text for the effective access of accurate information.  相似文献

Does a visual-orthographic deficit contribute to reading disability?   总被引:1,自引:0,他引:1  
In this study, visual-orthographic skills were defined as the ability to recognize whether letters and numerals are correctly oriented. Aims were to investigate whether visual-orthographic skills would contribute independent variance to reading, and whether children with a visual-orthographic deficit would be more impaired readers than similar children without this deficit. Participants were 207 children, aged 8 to 10 years, who attended school in a small suburban community. Because of the evidence that phonological awareness and naming speed are strongly related to reading, visual-orthographic skills were entered into hierarchical regression analyses following these variables. With age, verbal IQ, and verbal short-term memory also controlled, visual-orthographic skills accounted for significant independent variance in all reading measures. When children with a visual—orthographic deficit (29% of the sample) were compared with those without this deficit, they were significantly lower on all reading variables. At 8 to 10 years of age, reading progress of some children continues to be hampered by a problem in orthographic memory for the orientation of letters and numerals. Such children will require special attention, but their problems may be overlooked. As recommended by Willows and Terepocki (1993), there is need for further research on the phenomenon of letter reversals when they occur among children beyond first grade.  相似文献

Previous studies of visually symptomatic dyslexics have found that their contrast thresholds for pattern discrimination are the same as non‐dyslexics. However, when noise is added to the stimuli, contrast thresholds rise markedly in dyslexics compared with non‐dyslexics. This result could be due to impaired noise exclusion in dyslexics. Some dyslexics report a reduction in discomfort experienced while reading and show increased reading speed when using coloured lenses. We hypothesised that coloured lenses work by aiding noise exclusion. Thus the coloured lenses should help performance best under conditions of high visual noise. We measured contrast thresholds for discriminating symbols in the absence and presence of visual noise. The results showed that visually symptomatic dyslexics, who otherwise had elevated contrast thresholds for discriminating symbols in visual noise, had thresholds similar to non‐dyslexics when wearing coloured filters. These findings provide evidence that in visually symptomatic dyslexics coloured filters can improve noise exclusion to normal levels.  相似文献

Individual differences in RAN and reading: a response timing analysis   总被引:1,自引:0,他引:1  
Thirty 8–11‐year‐old children were administered tests of rapid naming (RAN letters and digits) and reading‐related skills. Consistent with the hypothesis that RAN predicts reading because it assesses the ability to establish arbitrary mappings between visual symbols and verbal labels, RAN accounted for independent variance in exception word reading when phonological skills were controlled. Response timing analysis of different components of RAN digits and letters revealed that neither average item duration nor average pause duration were unique predictors of reading skill. However, the number of pauses on digit naming predicted unique variance in exception word reading. Moreover, better readers paused more strategically than poorer readers (e.g. more often at the ends of lines). We suggest that rapid automatised naming may in part reflect differences in strategic control that are a result of differences in reading practice and experience.  相似文献

Two experiments investigated the use of orthographic analogies in 6 year olds. In Experiment 1, 26 children were shown CVC clue and target word pairs sharing either rimes (`fork' – `pork'), heads (`fork' – `ford') or were controls (`fork' – `hurl'). A modest advantage for rime-clued over head-cluedtargets was unreliable over by-subject and by-item analyses. Improvements in target word reading were correlated with pretest scaffolding errors (e.g. `pork' misread as `park'). In Experiment 2, 50 children were pretaught three clue words for each target word before being shown words that shared either rimes (`leak' – `peak'), or medial vowel digraphs (`leak') – `bean'), or were controls (`leak' – `herd'). A modest advantage for rime-clued over vowel digraph-clued targets was again unreliable over by-subject and by-item analyses. Neither rime nor phoneme awareness measures were correlated with rime inference use. Vowel, but not rime inference, was correlated with scaffolding errors. Rime detection was the strongest predictor of reading ability, whereas phoneme segmentation was the strongest predictor of the use of scaffolding errors.  相似文献

In this review, the origins and history of a test of rapid automatized naming (RAN) are traced from nineteenth-century classical brain-behavior analyses of cases of acquired “alexia without agraphia” through adaptations to studies of normal and reading disabled children. The element of speed (of responding verbally to a visual stimulus) was derived from a test of color naming developed over 50 years ago as a bedside measure of recovery from brain injuries. Merging the “visual-verbal” connection essential to reading (specific) with the response time element (general), RAN turned out to be a useful correlate and predictor of reading competence, accounting even for variance beyond that accounted for by timed tests of discrete naming. As one of the two deficits highlighted in the Double Deficit hypothesis with phonological awareness, RAN has emerged as something more than a particularly difficult challenge to a unitary phonological retrieval deficit, and has itself been subjected to further dissection. Coming full circle to its origins, recent research suggests that RAN taps both visual-verbal (language domain) and processing speed (executive domain) contributions to reading.  相似文献

Performance of hearing-impaired students on selected tests of visual processing and the relationship between performance on those measures and on a test of reading comprehension were investigated. Seventy-seven subjects, all 7- and 8-year-olds, were tested using the MVPT, ITPA Sequential Memory Subtest, VADS, Jordan, VMI, Slingerland, and SAT-HI. Scores of the hearing-impaired subjects failed to match those of the hearing norm sample of the VADS test but no systematic differences were found on the other tests of visual processing. Performance IQ was strongly associated with both visual processing and reading scores. Significant portions of the variance in reading scores were explained by IQ and performance on tests of memory for visual stimuli. Visual tests without a memory component failed to explain significant portions of the variance in reading performance.  相似文献

Some cognitive processes may be shared between reading comprehension and reading fluency, while others may be independent. In this longitudinal study, 127 Chinese children in grades 1–2 were tested three times (T1–T3) to explore the contributions of early morphological awareness and rapid automatized naming (RAN) to subsequent reading comprehension and reading fluency. The results demonstrated that both T1 morphological awareness and RAN directly and significantly explained a similar amount of variance in T3 reading comprehension and reading fluency. T1 Morphological awareness predicted T3 reading comprehension via T2 word-reading accuracy but not word-reading fluency, whereas the indirect influence of T1 RAN on T3 reading comprehension was not significant. In contrast, morphological awareness predicted reading fluency via word-reading accuracy and fluency, while RAN predicted it only via word-reading fluency not accuracy. The findings add to the growing literature by providing evidence of the similarities and differences in the cognitive underpinnings of reading comprehension versus reading fluency in Chinese children.

The purpose of this study was to develop and verify the Index of Science Reading Awareness (ISRA) based on a model of an efficient, successful interactive-constructive science reader and three independent metacognitive awareness domains. Several researchers have noted the need for efficient, reliable, and valid measures of metacognition. ISRA data collected on 532 students (Grades 4–8) were analyzed using factor analyses, linear structural modeling, and analyses of variance (ANOVAs) to help verify the model and the test. The factor analyses and linear structural modeling indicated that these data did not support the assumption about the three independent metacognitive awareness domains, but suggested that the model and the test were structured around the design features of science reading, science text, and science reading strategies. One-way ANOVAs indicated significant, predicted reading ability and gender differences but unexpected grade-level differences. The composite metacognitive awareness data indicated that most Grade 4–8 students have surface knowledge about science reading, science text, and science reading strategies, and indicated specific targets for explicit science reading instruction. © 1998 John Wiley & Sons, Inc.

This study examined the extent to which mora deletion (phonological analysis), nonword repetition (phonological memory), rapid automatized naming (RAN), and visual search abilities predict reading in Japanese kindergartners and first graders. Analogous abilities have been identified as important predictors of reading skills in alphabetic languages like English. In contrast to English, which is based on grapheme-phoneme relationships, the primary components of Japanese orthography are two syllabaries—hiragana and katakana (collectively termed “kana”)—and a system of morphosyllabic symbols (kanji). Three RAN tasks (numbers, objects, syllabary symbols [hiragana]) were used with kindergartners, with an additional kanji RAN task included for first graders. Reading measures included accuracy and speed of passage reading for kindergartners and first graders, and reading comprehension for first graders. In kindergartners, hiragana RAN and number RAN were the only significant predictors of reading accuracy and speed. In first graders, kanji RAN and hiragana RAN predicted reading speed, whereas accuracy was predicted by mora deletion. Reading comprehension was predicted by kanji RAN, mora deletion, and nonword repetition. Although number RAN did not contribute unique variance to any reading measure, it correlated highly with kanji RAN. Implications of these findings for research and practice are discussed.  相似文献

This study compared the performance of normal, primary, and secondary reading groups on intersensory and intrasensory tasks requiring paired and serial recall. Auditory and visual stimulus pairs composed of digits from 1 to 9 were presented using a Bell and Howell Language Master. Eight experimental tasks (four intersensory and four intrasensory) that required paired and serial verbal recall with an alteration of the first recalled modality (auditory or visual) were used. Ten trials of each of the eight experimental conditions were used with three pairs of stimuli presented at 2-second intervals. Three types of recall errors were scored for each task: gross (omission or substitution of digits), order (digit out of sequence), and interchange (inversion of digits). A multivariate analysis of variance was carried out for the reading groups × tasks × error types. The level of recall errors on bisensory tasks (auditory and visual) was related to the reading diagnostic groups. All readers exhibit similar patterns in the processing of bisensory information; however, unique differences were found among normal, primary, and secondary readers. A summary profile is given of the effects of task parameters among the groups (normal, primary, and secondary readers) in the processing of bisensory tasks.  相似文献

In an earlier training study we found that the use of visual support in phonemic segmentation training provided no additional value for poor readers and spellers from schools for children with learning disabilities, having problems segmenting speech (Kerstholt, van Bon & Schreuder 1994). Previous research (e.g., Hohn & Ehri 1983) suggests, however, that visual support – such as alphabet letters – does facilitate the segmentation teaching of preschoolers. Hence, it was expected that visual support would be beneficial in phonemic segmentation training only prior to formal reading and spelling instruction. The purpose of the present study was to test this expectation. One group of preschoolers was trained in phonemic segmentation with diagrams and alphabet letters as visual support, another group was trained without visual help. Results show the preschoolers to improve their phonemic segmentation, reading and spelling skill significantly. It made no difference, however, whether the children were trained in phonemic segmentation with or without the help of visual support. The findings of the present study and those of our earlier study indicate visual support to be useful in phonemic segmentation training only under certain conditions. It is suggested that differences in orthographic properties of the languages involved may explain the difference between the Anglo-Saxon studies that did show an additional effect of letters and a number of Dutch studies that did not.  相似文献

This article explores the multilayered nature of a single picture book by Anthony Browne and the sophisticated responses (including their own pictures) children aged 4–11 bring to interpreting such a text. Emphasis is laid on the high-level cognitive skills involved in reading visual images and links are made between seeing and thinking. Some features of the children's understanding are examined in detail; for example, how they interpret visual imagery and deal with a variety of challenging artistic features, and how their drawings show knowledge and feelings they are not yet able to articulate. The findings also suggest that some children who are not yet confident at reading print have developed impressive capacities for analysing image.  相似文献

Attentional control was investigated as a possible third component of reading comprehension, along with decoding and language comprehension, within the Simple View of reading (Gough & Tunmer RASE: Remedial and Special Education 7:6–10, 1986; Hoover & Gough Reading and Writing 2:127–160, 1990). Attentional control is the ability to suppress irrelevant prepotent responses and activate relevant responses. This ability may help coordinate decoding and language comprehension during reading. In an unselected sample of 67 eight-year-olds, attentional control contributed significant variance to reading comprehension after controlling for decoding and language comprehension. Further, attentional control was similar to language comprehension in the amount of unique variance accounted for. Five contrast measures were examined (performance IQ, print exposure, articulation speed, phonemic awareness, and verbal short-term memory), but none was as good a candidate for a third component of reading comprehension as attentional control.  相似文献

The primary aim of the current study was to identify the strongest independent predictors of reading comprehension using word reading, language and memory variables in a normal sample of 180 children in grades 3–5, with a range of word reading skills. It was hypothesized that orthographic processing, receptive vocabulary and verbal working memory would all make independent contributions to reading comprehension. The contributions of reading speed, receptive grammatical skills, exposure to print, visuospatial working memory and verbal learning and retrieval (a measure of longer-term retention) were also investigated. Working memory tasks that required the processing and storage of numerical and spatial material were used. One of the numerical working memory tasks was based on the number span task developed by Yuill, Oakhill, and Parkin British Journal of Psychology, 1989, 80, 351–361. A visuospatial equivalent of that task was developed from the forward Corsi block task [Corsi, Abstracts International, 1973, 34, 891]. The results revealed that, after controlling for age and general intellectual ability, the word reading and the language variables had a much stronger relation with reading comprehension than the memory variables. The strongest independent predictor of reading comprehension was orthographic processing since it captured variance in both word reading, language skills and verbal working memory. The forward Corsi task and performance on a measure of verbal learning and retrieval each made small independent contributions to reading comprehension but the contribution of verbal working memory was not significant. It was concluded that tasks measuring the interplay between short-term and long-term memory, in which new information is combined with information already stored in long-term memory, may better predict reading comprehension measured with the text available than working memory tasks which only have a short-term memory component.  相似文献
