After her 12-year-old son spent two years at a specialized school for
children with learning disabilities, Lisa Lunday decided he was ready for a more
challenging, mainstream environment. The school she chose, however, required all
students to study Japanese as part of its academically rigorous curriculum. Ms.
Lunday was unsure how her son, who is dyslexic, would cope.
The result surprised her. The boy, now 13, excelled in his Japanese studies.
His lettering of Japanese characters was sharp and distinct. That was in stark
contrast to his writing in English, which appeared to be the work of a
kindergartner. Sometimes his English letters were so poorly composed that they
were hard to read, a common problem among dyslexics.
"I looked at his Japanese binder and was amazed at how perfectly formed
everything was," says Ms. Lunday, of San Mateo, Calif. "Just comparing two
pieces of paper tells the story."
Experiences like that of the Lundays are providing scientists and educators
with clues about how people with dyslexia learn and how best to teach them.
Researchers have long observed that some dyslexics have an easier time with
languages like Japanese and Chinese, in which characters represent complete
words or ideas, than they do with languages like English, which use separate
letters and sounds to form words.
A 12-year-old dyslexic boy in San Mateo, Calif., has difficulty writing in
English, his native language. But in his Japanese studies class he is able to
compose characters sharply and distinctly. Scientists say Japanese symbols are
more like pictures than letters, which can be easier for many dyslexics to
reproduce.

defines the idiom 'an eye for an eye.'
In the English assignment, the boy defines the idiom "an eye for an eye" as:
Revenge or punishment exactly like the original crime or offense. He also writes
a scenario: Bob traded an eye for an eye when he took his sister's [the next
word is unreadable] and she threw it at him.

Now, recent brain-imaging studies are identifying possible reasons for the
differences, and education experts say such research could point the way to
improved teaching techniques.
"There are very real differences in the brain's reading circuit for an
alphabet as opposed to a language like Chinese," says Maryanne Wolf, a professor
of child development and director of the Center for Reading and Language
Research at Tufts University in Medford, Mass. Dyslexics "think visually. They
analyze patterns," she says.
Character-based languages are mastered through memorization, a skill that
dyslexics tend to rely on more than do typical language learners, says Sally
Shaywitz, co-director of the Yale Center for Dyslexia and Creativity in New
Haven, Conn. And language characters are more like pictures than letters, which
can be easier for many dyslexics to reproduce, she says.
Dyslexia, the most common of all learning disabilities, is a neurologically
based disorder that causes difficulties in language-related tasks. It occurs
regardless of a person's intelligence or level of education. As many as one in
five people have dyslexia to some degree, according to the Connecticut
Longitudinal Study, a long-term study of about 450 school-age children that
concluded in the early 2000s.
A study of school-age children published last year in Psychological Science
compared how good readers and dyslexic readers learn language. Using
brain-imaging technology, researchers at the Yale Center found that when people
with dyslexia read in English they rely on the same region of the brain as do
readers of kanji, a character-based language in Japan.
By contrast, a somewhat different region of the brain is used by good English
readers as well as by children reading kana, another Japanese language, but one
in which each character represents a sound, as in English.
"People with dyslexia have difficulty splitting words into their component
sounds," a skill known as decoding, says Claudia Koochek, the head of the
Charles Armstrong School in Belmont, Calif., which specializes in teaching
children with language-based disabilities.
Learning experts don't suggest that studying Chinese or Japanese will help
dyslexics learn to read English; there's no getting around the fact that reading
English well requires being able to identify and blend sounds. But improved
understanding of the way dyslexics absorb character-based languages may help
educators fashion curricula.
The Arrowsmith School, a Toronto-based school for children with learning
disabilities, says it asks students as part of its reading program to memorize
words and characters in a variety of languages, including Chinese.
Annette Goodman, Arrowsmith's chief education officer, says the exercise is
aimed at strengthening visual memory, one part of the brain dyslexics rely on
for language tasks. That, in turn, can help them overcome some specific reading
challenges, such as learning irregular English words that don't follow typical
letter patterns, like 'school' or 'laugh,' she says.
"The purpose is not to teach language. It is to treat dyslexia," Ms.Goodman
says.
Dr. Wolf, whose research center also teaches children with dyslexia, says
that understanding the different ways in which dyslexics' brains are wired has
helped her adapt teaching programs for their needs. Repetition is important, she
says, to help dyslexic kids memorize visual patterns of words and letters.
Dyslexics may need 10 times as much exposure to the language patterns as do
traditional learners, she says.
In dyslexics, some essential connections between the right and left sides of
the brain are weaker or slower than in typical learners, Dr. Wolf says. To get
around this, she says she attempts to simulate these connections by engaging the
kids in a wide range of simultaneous exercises, including teaching letters,
sounds, words and their meanings.
Dyslexics exhibit a wide range of problems with reading and writing language,
and future research will be aimed at enabling teachers to tailor their
approaches to each dyslexic learner, Dr. Wolf says. Through a combination of
brain imaging, genetics, linguistics and educational know-how, she expects
interventions will increasingly become early and personalized.
