Bilingual and dyslexic in one language only

Wydell and Butterworth reported the case study of an English-Japanese bilingual with monolingual dyslexia. Suggesting that any language where orthography-to-phonology mapping is transparent, or even opaque, or any language whose orthographic unit representing sound is coarse (i.e. at a whole character or word level) should not produce a high incidence of developmental phonological dyslexia, and that orthograpy can influence dyslexic symptoms

Research text requiring paraphrasing and copy-editing

Using both PET and fMRI, Paulescu et al. 2001, full paper both the abstract, and the final paragraph need paraphrasing to be included in the article

A study comparing children's reading acquisition rates between different orthography of European Language (alphabet writing systems), Seymour et al. 2003, found that children from a majority of Europe Seymour et al abstract content could be paraphrased and used on Managing dyslexia: alphabetic orthography

logographic dyslexia

Although alphabetic dyslexia seems to originate in the left temporoparietal and occipitotemporal areas of the brain, recent studies indicate that logographic dyslexia is associated with part of the left middle frontal gyrus. This suggests that "the structural and functional basis for dyslexia varies between alphabetic and nonalphabetic languages.

FULL ABSTRACT or full article

In other words, alphabetic and logographic dyslexia are most likely separate disorders; a person with alphabetic dyslexia would not necessarily also have logographic dyslexia, and vice versa.

The distinction between these two forms of dyslexia has led to promising therapeutic research. One study led by Alberto Sáez-Rodríguez discovered that syllabic logograms could act as a learning aid to alphabetic-dyslexic English-speaking children.

Syllabic Writing

Syllabaries often begin as simplified logograms, as shown here with the Japanese katakana writing system. To the left is the modern letter, with its original Chinese form on the right.

A syllabary is a set of written symbols that represent (or approximate) syllables, which make up words. A symbol in a syllabary typically represents an optional consonant sound followed by a vowel sound.

Languages using syllabaries

Languages that use syllabic writing include Mycenaean Greek (Linear B), the Native American language Cherokee, the African language Vai, the English-based creole language Ndyuka (the Afaka script), and Yi language in China. Nü Shu is a syllabary that was used to write the language of the Yao people in China. The Chinese, Cuneiform, and Maya scripts are largely syllabic in nature, although based on logograms. They are therefore sometimes referred to as logosyllabic. The Japanese language uses two syllabaries together called kana, namely hiragana and katakana (developed around AD 700). They are mainly used to write some native words and grammatical elements, as well as foreign words, e.g. hotel is written with three kana, ホテル (ho-te-ru), in Japanese. Because Japanese uses many CV (consonant + vowel) syllables, a syllabary is well suited to write the language. As in many syllabaries, however, vowel sequences and final consonants are written with separate glyphs, so that both atta and kaita are written with three kana: あった (a-t-ta) and かいた (ka-i-ta). It is therefore sometimes called a moraic writing system.
