Phonemic awareness,naming, visual symbol processing,and reading

This study examined differences between adequate and poor readers in phonemic awareness, rapid continuous and confrontation naming, and visual symbol processing. It also investigated which of these skills make independent contributions to word recognition, pseudoword reading, and reading comprehension. Subjects were 170 school referrals of average intelligence, aged 6 to 10 years. The strongest differentiators of adequate and poor readers, with IQ and reading experience controlled, were phonemic awareness, naming speed for letters and pictured objects, and visual symbol processing. Letter naming speed made the largest independent contribution to word recognition, phonemic awareness to pseudoword reading, and object naming speed to reading comprehension. Confrontation picture naming accounted for minimal variance in reading skills, when IQ was controlled. It was concluded that tasks of naming speed, phonemic awareness, and visual symbol processing are valuable components of a diagnostic battery when testing children with possible reading disability.     

Rapid naming speed and reading across languages that vary in orthographic consistency

The objective of this study was to examine how rapid naming speed is related to reading ability across languages that vary in orthographic consistency. Forty English-speaking Canadian children, 40 Greek-speaking Cypriot children, and 40 Chinese-speaking Taiwanese children were administered RAN, reading accuracy, and reading fluency tasks in grade 4. The results revealed that across languages there were no statistically significant differences in the correlations between RAN and reading. However, a subsequent analysis of the RAN components—articulation and pause time—revealed that different RAN components may be responsible for the RAN-reading relationship across languages. Implications for existing theories relating RAN to reading are discussed.     

Developmental changes in the contributions of phonological processing skills to Chinese character reading and arithmetic

This study examined the associations of phonological processing skills with reading and arithmetic ability in Chinese kindergartners (Mage = 5.56 years), third graders (Mage = 9.72 years), and fifth graders (Mage = 11.75 years) (N = 413) of Han descent. The results showed that phonological awareness and rapid automatized naming (RAN) showed stronger relations than phonological memory with reading and arithmetic across grades. Furthermore, the associations of phonological awareness and RAN with reading were much stronger in kindergartners than in primary school children, whereas their relationships with arithmetic remained stable across grades. Among phonological skills, phonological awareness has a unique influence on arithmetic that is independent of Chinese character reading in third-graders and kindergartners. In contrast, RAN uniquely explained the variation in arithmetic skills in fifth graders when reading was statistically controlled for. These findings have important implications for understanding the co-development of reading and arithmetic across grades and raise the possibility of training in phonological awareness and/or RAN to help children at risk for learning disabilities.     

Transfer of reading-related cognitive skills in learning to read Chinese (L1) and English (L2) among Chinese elementary school children

This study investigated transfer of reading-related cognitive skills between learning to read Chinese (L1) and English (L2) among Chinese children in Hong Kong. Fifty-three Grade 2 students were tested on word reading, phonological, orthographic and rapid naming skills in Chinese (L1) and English (L2). The major findings were: (a) significant correlations between Chinese and English measures in phonological awareness and rapid naming, but not in orthographic skills; (b) significant unique contribution of Chinese and English rapid naming skills and English rhyme awareness for predicting Chinese word reading after controlling for all the Chinese and English cognitive measures; (c) significant unique contribution of English phonological skills and Chinese orthographic skills (a negative one) for predicting English word reading after controlling for all the English and Chinese cognitive measures; and (d) significant unique contribution of Chinese rhyme awareness for predicting English phonemic awareness. These findings provide initial evidence that developing reading-related cognitive skills in English may have facilitative effects on Chinese word reading development. They also suggest that Chinese orthographic skills or tactics may not be helpful for learning to read English words among ESL learners; and that Chinese rhyme awareness facilitates the development of English phonemic awareness which is an essential skill predicting ESL learning.     

Phonological basis in reading disability: A review and analysis of the evidence

Poor readers are known to do consistently worsethan their normal reading peers on tasks ofphonological processing. They are characterizedby their difficulties in printed wordrecognition, phonological awareness andphonological decoding. An increasing body ofevidence points to deficits in speechperception as a source of subtle but ramifyingeffects in reading impaired children andadults. These deficits may be traced to poorlycoded phonological representations. Thisarticle will attempt to explain poor readers'difficulties in phonological coding by drawingon a gestural account speech development.Implications of this approach for readingintervention will be presented.     

Letter Processing and the Formation of Memory Representations in Children with Naming Speed Deficits

The ability to recognize letter patterns within words as a single unit is important for fluent reading. This skill is based on previously established memory representations of common letter patterns. The ability to form these memory representations may be impaired in some poor readers, particularly readers with naming speed deficits (NSD). This study explored factors that influence letter processing and the subsequent formation of memory representations of letter strings in children with and without a NSD. Children were presented with a letter string, followed by a probe unit that was either a single letter, a two-letter cluster, or a repetition of the whole string. Children indicated whether or not the probe had been present in the preceding string. Two factors were manipulated: (a) amount of time to process the initial letter string, and (b) level of orthographic structure present in the letter string. Results indicated that overall, children with NSD performed less accurately than children without NSD. However, children with NSD showed no differential benefit in performance as a result of longer time to process a letter string. In addition, all readers were able to make use of the orthographic structure in a letter string to aid performance. Implications of results for establishing memory representations of letter strings are discussed.     

The role of achievement strategies on literacy acquisition across languages

We examined the importance of children’s achievement strategies in different literacy outcomes in three languages varying in orthographic consistency: Chinese, English, and Greek. Eighty Chinese-speaking Taiwanese children, 51 English-speaking Canadian children and 70 Greek children were assessed on measures of phonological awareness, rapid automatized naming, reading fluency, and spelling. The children’s use of a task-focused versus task-avoidant achievement strategy in the classroom context was rated by their teachers. The results indicated that the teacher-rated task-focused behavior was a significant predictor of spelling and to a lesser extent of reading fluency and that its effects were comparable across languages.     

IQ vs phonological recoding skill in explaining differences between poor readers and normal readers in word recognition: Evidence from a naming task

The aim of this study was to investigate whether differences inreading performance between poor readers and normal readers could bebetter explained by phonological recoding deficiences than IQ. A sampleof 132 Spanish children was classified into four groups according to IQ(<80; 81--90; 91--109; 110--140) and into two groups based on readingskills (poor readers vs normal readers). A word naming task was alsoadministered. We manipulated the word parameters (length, positionalsyllable frequency, and word frequency) and nonword parameters (lengthand positional syllable frequency) to find out whether students withreading disabilities would have more difficulties than normal readers innaming words under conditions that require extensive phonologicalcomputation. The results demonstrated that there were differencesbetween Spanish children who were normal readers and those who were poorreaders, independent of their IQs.     

Spelling predictors; investigating the role of phonological ability and rapid naming in a large cross-sectional British study

This study aimed to identify predictors of single word spelling performance in children using a novel test containing regular words, irregular words and pseudowords. We assessed reading ability, letter-sound knowledge, phonological awareness (PA) and rapid automatised naming (RAN) in children aged 4–12 years (N = 641). Mixed model analyses with hierarchical nested data were conducted with Year_group (Yr R to Yr 6) included as a factor, PA and RAN as predictors, and reading and letter-sound knowledge as covariates. For irregular word spelling, PA and RAN were significant predictors, but the associations were dependent upon the year the children attended. Interestingly, for regular words and pseudowords PA was not significantly related. For pseudowords, only RAN was a significant predictor and only in Yr 2. We argue that a better understanding of spelling development can be achieved using tools that distinguish between regular and irregular words and pseudowords, as different processes seem to be associated with the different types of letter string across the variable levels of spelling experience.     

From letter names to word reading: The nascent role of sublexical fluency

Information processing theory suggests that sublexical fluency skills are important to word reading development, but there are few supportive data. This study investigated if sublexical fluency (letter name fluency, letter sound fluency, and phoneme segmentation fluency) contributed to the development of word reading and spelling in 92 kindergarten children. The pattern of findings suggests that, as early as kindergarten, sublexical fluency skills explain a small, but significant, amount of unique variance in literacy outcomes when also considering the influence of accuracy in these skills. Also, growth in sublexical fluency skills is related to both word reading and spelling proficiency at the end of kindergarten. We suggest that knowledge of early literacy skill development may be enhanced by attention to sublexical fluency and that these skills, specifically letter sound fluency, may provide the mechanism that supports early word reading and spelling.     

Orthographic processing is a key predictor of reading fluency in good and poor readers in a transparent orthography

We used structural equation modeling to investigate sources of individual differences in oral reading fluency in a transparent orthography, Russian. Phonological processing, orthographic processing, and rapid automatized naming were used as independent variables, each derived from a combination of two scores: phonological awareness and pseudoword repetition, spelling and orthographic choice, and rapid serial naming of letters and digits, respectively. The contribution of these to oral text-reading fluency was evaluated as a direct relationship and via two mediators, decoding accuracy and unitized reading, measured with a single-word oral reading test. The participants were “good” and “poor” readers, i.e., those with reading skills above the 90th and below the 10th percentiles (n = 1344, grades 2–6, St. Petersburg, Russia). In both groups, orthographic processing skills significantly contributed to fluency and unitized reading, but not to decoding accuracy. Phonological processing skills did not contribute directly to reading fluency in either group, while contributing to decoding accuracy and, to a lesser extent, to unitized reading. With respect to the roles of decoding accuracy and unitized reading, the results for good and poor readers diverged: in good readers, unitized reading, but not decoding accuracy, was significantly related to reading fluency. For poor readers, decoding accuracy (measured as pseudoword decoding) was related to reading fluency, but unitized reading was not. These results underscore the importance of orthographic skills for reading fluency even in an orthography with consistent phonology-to-orthography correspondences. They also point to a qualitative difference in the reading strategies of good and poor readers.     

Invented spelling in kindergarten: The relationship with finger-point reading

The relationship between ability to invent spellings and ability to finger-point read memorized text was examined in 109 kindergartners in whole-language classrooms. It was hypothesized that letter name knowledge and phonemic awareness would account for ability in finger-point reading, but that invented spelling, because it requires the left-to-right alphabetic principle as well, would account for additional variance, and this turned out to be the case. It was also hypothesized that although initial phoneme spellings would be easier than those in other positions, and would be a factor in the voice-print match in finger-point reading, final phonemes would also play a significant role. This turned out to be the case for children who were able to read only a word or two, as well as for more capable beginners. Results were consistent with Ehri's (1992) model of phonetic-cue sight reading in which letters are utilized from both initial and final positions.     

The role of phonological and syntactic awareness in second-language reading: The case of Spanish-speaking learners of French

Spanish-speaking learners of French, aged 9 to 11 years old, were tested after approximately 7months of French instruction to explore the contribution of phonological and syntactic awareness in L2 in 4 components of L2 reading, taking oral competence in L2 andreading in L1 into account. Phonological tasksin L2 better explain decoding. Word recognitionthrough the visual route is best explained bythe corresponding ability in L1. Sentencecomprehension is best explained by oralcompetence in L2, although it is stronglycorrelated with syntactic awareness. Finally,text comprehension is explained by thecorresponding ability in L1, althoughcorrelations with syntactic awareness and oralcompetence are strong. Theoretical implicationsare derived from these findings, and questionsrelative to the subjects' age and level ofbilingualism as well as methodological issuesare discussed.     

The word decoding strategies of Hebrew readers with and without hearing impairments: Some insight from an associative learning task

The aim of this study was to elucidate the word decoding strategies of Hebrew readers with prelingually-acquired, severe hearing impairments as opposed to regular Hebrew readers, and to determine their efficiency. The research paradigm used to clarify these issues asked participants to perform a sequence of three learning tasks, calling for the association of digits with (1) written Hebrew nouns, (2) with pseudo-homophones (PH) of these nouns, and (3) with nonsense words (NW) comprised of the same graphemes as the nouns. Ninety-two secondary school students, half of them hearing impaired (HI), performed the tasks in succession, with the word/digit association task (the primer) always being administered first. For two sub-groups, however, comprised of approximately half of the members of each of the groups, the order of the latter two tasks was reversed. As such, 23 of those who were HI and 24 of those who were not performed the PH/digit association task after the word/digit association task (primed), whereas for the remainder (unprimed), the word/digit association task was immediately followed by the NW/digit association task. It was expected that, for hearing readers but not for HI readers, the existence of homophony between the real words and the PHs in the primed condition would facilitate learning associations for the latter. This hypothesis, however, was not confirmed. Neither of the two primed groups exhibited sensitivity to homophony. This finding is particularly surprising with respect to the primed hearing group, since it totally contradicts current popular theories that assign phonology a central role in the processing of written materials by unimpaired readers.     

Structural invariance in the associations of naming speed,phonological awareness,and verbal reasoning in good and poor readers: A test of the double deficit hypothesis

The associations of multiple measures of speeded naming, phonological awareness, and verbal intelligence with word reading were examined in 51 poor readers and 74 good readers in third and fourth grade. Structural equation modeling was used to determine the extent to which these two groups exhibited structurally invariant patterns of associations among the constructs. Results revealed that for poor readers, both speeded naming and phonological awarencess were significantly associated with word reading, but verbal intelligence had no association with it. In contrast, for good readers, phonological awareness and verbal intelligence were significantly associated with word reading, but naming speed was not. Findings are discussed in light of the double deficit hypothesis.     

The contribution of orthographic and phonological processes to word reading in young Norwegian readers

The dissociation between phonological and orthographic processes in word reading was investigated in a study involving 147 children in grade 3. The criterion measure was a timed word reading test. Two tasks assessed phonological skills and two tasks assessed orthographical skills. Orthographic ability accounted for variance in word reading even after phonological ability had been controlled. Poor readers differed from skilled readers in the way phonological and orthographic factors were balanced. The relationship between the two factors was fairly strong among poor readers, whereas the correlation was low for more skilled readers. Furthermore, phonological factors played a much stronger role in explaining the variance in word reading among poor readers, while on the other hand, orthographic factors were more powerful among skilled readers.

This paper presents a review of currentknowledge concerning the reading skills ofchildren and adults with Williams syndrome. The paper begins by highlighting themethodological issues surrounding research onreading in atypical populations and discussesthe issue of comparison groups. It proceeds toreview evidence from studies that havedescribed the reading profile observed inWilliams syndrome in relation to the documentedcognitive and linguistic profile, andspecifically examines the relationship betweenreading and phonological skills. The paperadvocates a more dynamic developmental approachto the study of reading in atypical populations.     

Development of phonological, morphological, and orthographic knowledge in young spellers: The case of inflected verbs

This study was designed to simultaneously investigate the influence of phonological, morphological, and orthographic awareness skills on the ability to spell inflected verbs in structured spelling tasks. Children in grades 1, 2, and 3 (n=103) spelled inflected past and progressive tense verbs and completed awareness tasks. Developmental changes occurred in the ability to include the inflected ending, to spell the ending consistently reflecting the correct morphological unit, and to affix the ending using the correct orthographic pattern. The contributions of phonological, morphological, and orthographic awareness to spelling development varied across the three grades but were similar for each sub-component, suggesting a developmental relationship between the ability to spell inflected verbs and linguistic and orthographic awareness.     

Effects of mora deletion,nonword repetition,rapid naming,and visual search performance on beginning reading in Japanese

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.
