Evaluation of the multiple-deficit hypothesis among dyslexic Arabic-speaking children.

This study examined the multiple-deficit hypothesis among Arabic-speaking elementary school students. A total of 90 students, divided into three main groups based on their performance on an Arabic word-reading task: dyslexic (n = 30), regular age-matched (n = 30), and 3rd-grade regular students, who were matched to the dyslexic group in regard to their reading proficiency level (n = 30). Participants underwent a nine-domain Arabic reading experiment that measured accuracy and fluency to evaluate general reading proficiency. The performance of Arabic dyslexic students was significantly worse than age-matched controls, but similar to young matched controls based on the reading level of each cognitive task. Moreover, dyslexic students showed deficits in three or more cognitive functions, depending on severity. This study adds to the limited empirical research on the double-deficit hypothesis and its extension to the multiple-domain model among young Arabic students.

The Role of Vowelization in Reading Comprehension of Different Arabic Genres.

The present study explored the influence of short vowelization in Arabic orthography on reading comprehension of different texts, different genres and on different levels, among students of different ages. It explored the influence of short vowelization in Arabic orthography on reading comprehension of texts from the Koran, informative texts, newspaper articles and poetry, by examining the influence of short vowelization on different levels of understanding among students from three cities and three Arab villages in the northern district of Israel. The results from the mixed design indicated that short vowelization improved the level of reading comprehension among the readers in each level of understanding and for each kind of text. The results indicated a greater improvement in reading comprehension among the young readers as compared to the older readers. The findings also showed that short vowelization improved the performance of the fifth graders, more so than for ninth graders. Furthermore, short vowelization did not influence the performance of the seventh graders.

The Role of Short Vowels in Reading Arabic: A Critical Literature Review.

The purpose of the present review is to examine the studies that tested the role of short vowels in reading Arabic. Most of the studies are reviewed in this paper and two contradicted data are presented: data that support positive contribution of short vowels in reading Arabic, and the other data that reject the assumption that short vowels contribute to the quality of reading, and suggest that these short vowels do not add any positive contribution and maybe the opposite; short vowels hinder reading in Arabic orthography. The results are criticized indicating some methodological problems and suggestions for further studies are presented.

The Role of Short Vowels in Arabic Listening Comprehension.

The goal of the present study was to investigate the effect of short Arabic vowels on listening comprehension. It is well documented that short vowels affect reading and reading comprehension in Arabic literacy. Since reading comprehension and listening comprehension share many commonalities, it is assumed that short vowels will positively affect listening comprehension too. Two listening conditions were presented to students in three grade levels, 7th, 10th and 12th grades: a fully vowelized text and the second without short vowels (on ends of words). Students had to listen and answer multiple choice comprehension questions about the read aloud texts. Further, interviews were conducted with 10 volunteered students from each grade level to get their feedback about their experience. The results indicated significant differences between the two listening conditions in favor of the fully vowelized condition. The results are discussed in relation to different orthographies, reading comprehension, phonology, working memory and comprehension.

The Impact of the Position of Phonemes and Lexical Status on Phonological Awareness in the Diglossic Arabic Language.

This study aimed at examining the impact of phonemes and lexical status on phonological manipulation among pre-school children. Specifically, we tested the impact of phonemic positions (initial vs. final) and lexical status (shared, spoken, standard and pseudo-words) on phonemic isolation performance. Participants were 1012 children from the second year (K2) and third year (K2) in kindergarten. The results of the ANOVAs revealed significant effect of the phonemes' position on the phonemic isolation performance whereas the performance was easier with the initial rather than the final phonemes. Also, the repeated measure analysis showed that the lexical status also impacts the phonemic isolation performance. The performance in pseudo-words was lower than all the others. However, the other clusters of real words did not differ. The results are discussed in the light of previous findings in the literature and of differences in the syllabic structures of the words that may influence phonological awareness.

The Reading of Deaf Arabic Children in Israel.

Studies on the reading acquisition of deaf children investigate the similarities and differences in the reading process between these readers and typical hearing readers. There is no consensus on the nature of the reading process among deaf readers, whether they use the same reading processing strategies as typical readers or depend on other strategies to close the gap. The present study aimed to test the types of strategies used to process written words by deaf Arabic readers with prelingual deafness, compared to their hearing peers, and to test the effectiveness of deaf readers' use of these strategies. Three experimental paradigms were tested. The findings indicated that deaf Arabic readers rely on essentially similar processing strategies to those used by hearing readers. However, deaf Arabic readers employ these strategies with significantly less effectiveness. The results are discussed in light of international data.

Cognitive Retroactive Transfer of Language Skills From English as a Foreign Language to Hebrew as the First Language.

The study tested whether cognitive retroactive transfer (CRT) of language skills from English to Hebrew takes place; specifically, whether an improvement in linguistic and meta-linguistic skills in English as a foreign language (FL) would lead to an improvement in these skills in Hebrew as the first language (L1). The participants consisted of 124 students in Grade 6 who were randomly assigned to an experimental group or a control group. Each group was further divided into readers with dyslexia, poor readers, and typical readers groups. The experimental group participated in an English intervention program designed for this study. All participants were administered a battery of pre- and post-treatment tests in linguistic and meta-linguistic skills in Hebrew and in English. The findings supported the existence of CRT from skills in English to skills in Hebrew with reference to most of the variables in the domains of reading, writing, and language skills. The improvement in most of the linguistic and meta-linguistic tasks in both English and Hebrew was significantly higher in the experimental group compared with the control group. The innovation of this study was in testing CRT of linguistic and meta-linguistic skills from English to Hebrew. Limitations and direction for future research are discussed.

The role of morphology and short vowelization in reading Arabic among normal and dyslexic readers in grades 3, 6, 9, and 12.

This study was an investigation of several Arabic reading measures among dyslexics and normal Arabic readers across different ages (grades 3, 6, 9, and 12): the role of morphology, short vowelization (phonological and syntactic skills), spelling, reading isolated words, and reading comprehension. The results of the one-way ANOVAs indicated clear differences between the dyslexic readers and the normal readers on all reading measures. However, the stepwise regression analysis revealed consistent orthographic results: morphology (identification and/or production) and spelling were generally the most powerful predictors of both reading accuracy and reading comprehension among dyslexic and normal readers across these different age groups. The results are discussed in terms of the characteristics of the Arabic orthography and the heavy reliance of readers at all levels and ages on orthographic factors in reading.

Phonological errors predominate in Arabic spelling across grades 1-9.

Most of the spelling error analysis has been conducted in Latin orthographies and rarely conducted in other orthographies like Arabic. Two hundred and eighty-eight students in grades 1-9 participated in the study. They were presented nine lists of words to test their spelling skills. Their spelling errors were analyzed by error categories. The most frequent errors were phonological. The results did not indicate any significant differences in the percentages of phonological errors across grades one to nine.Thus, phonology probably presents the greatest challenge to students developing spelling skills in Arabic.

The effect of consanguineous marriage on reading disability in the Arab community.

The present study examined the effect of consanguineous marriage in the Arab community on reading disabilities of offspring. It examined whether the rate of reading disabilities was higher among offspring of first-cousin parents than offspring of unrelated parents; and whether reading-disabled children of first-cousin parents were more disabled in phonological awareness and phonological decoding than reading-disabled children of unrelated parents and normally reading younger children. These questions were investigated among 814 pupils of the 4th, 5th, and 6th grades, using word recognition and reading comprehension tests. Two experimental groups were chosen from this population. These were a reading-disabled group of 22 pupils who were children of first-cousin marriages and 21 pupils who were children of unrelated parents. A control group was also selected, consisting of 21 younger normally reading pupils at the same reading level. All the groups were tested on non-words, real words, phonological, orthographic and working memory measures. The results indicated that the rate of reading disabilities among children of first-cousin parents was higher than that of with children of second-cousin parents, distantly related parents, or unrelated parents. Further, no differences were found in phonological awareness and decoding between the two reading-disabled groups. Moreover, the results indicate a significant advantage of the younger normal readers over the reading-disabled children in the measures of phonological awareness, decoding, and orthographical knowledge that requires spelling. However, in reading common words and choosing words in context, the performance of the reading-disabled groups and the normally reading group were similar. It has been suggested that further research is needed to evaluate the role of intelligence, nevertheless our results provide new evidence for a genetic basis to reading disabilities.

Reading, syntactic, orthographic, and working memory skills of bilingual Arabic-English speaking Canadian children.

This study assessed the reading, language, and memory skills of 56 bilingual Arab-Canadian children age's 9-14. English was their main instructional language, and Arabic was the language spoken at home. All children attended a Heritage Language Program in Toronto where they were taught to read and write Arabic. The children were administered word and pseudo-word reading, language, and working memory tests in English and Arabic. The majority of the children showed at least adequate proficiency in both languages. There was a significant relationship between the acquisition of word and pseudo-word reading working memory, and syntactic awareness skills in the two languages. The poor readers in Arabic had lower scores on all linguistic tasks, except the visual task. There were no significant differences between bilingual English Arabic children and monolingual English-speaking children on the reading, language, and memory tasks. However, bilingual English Arabic children who had reading problems in English had higher scores on English pseudo-word reading and spelling tasks than monolingual English-speaking children with reading disabilities, probably because of positive transfer from the regular nature of Arabic orthography. In this case, bilingualism does not appear to have negative consequences for the development of language reading skills in both languages--Arabic and English--despite the different nature of the two orthographies.
