Abstract
This thesis investigates dyslexia and the cognitive-linguistics skills, namely phonological awareness, orthographic knowledge, morphological awareness and rapid naming, of bilingual learners in Singapore whose first language is English and second language is Chinese. The two main research aims are to investigate whether the English-Chinese bilingual learners with dyslexia diagnosed only in English are weaker than their typical counterparts in reading and all cognitive-linguistic skills in both languages or either language, and to investigate which cognitive-linguistic skills are strong predictors of reading in each language. Results show that the bilingual learners with dyslexia performed significantly poorer than their typical counterparts in reading and all cognitive-linguistic skills in both languages, although their dyslexia were diagnosed only in English. Results also found all English cognitive-linguistic skills predictive of English word reading, especially the unique predictive roles of morphological awareness and orthographic knowledge after rapid naming and phonological awareness were controlled. However, only rapid naming and morphological awareness were found to be predictive of Chinese word reading. The results suggest that dyslexia may manifest differently in reading and cognitive-linguistic skills of English and Chinese languages in the English-Chinese bilingual learners, based on the two different predictive models with different empirically and theoretically supported orders of cognitive-linguistic skills as predictors for reading development in the two languages. The difference in the unique contributions of the four cognitive-linguistic skills underlying the reading development of both languages may suggest the difference lies in language structure and instruction. Keywords: dyslexia, bilingualism, English reading, Chinese reading, cognitive-linguistic skills
