Today I was listening to Uta Frith on the
radio.
Twelve
years ago, on the suggestion of a colleague of hers. I used rapid digit naming as an alternative to
rapid automatic naming of text to find out how the dyslexic students were
performing compared with non-dyslexic adults. As Uta reported the mean for the
dyslexic students was around 135 digits
per minute.
The same as for rapid word naming.
The inference in her research was that this was evidence for a
phonological deficit.
However when the students were asked to
undertake RDN using their optimal settings on the computer screen their performance
average 184 digits per minute which was the same s the RAN mean of non-dyslexic
students.
It was
also the same as reported for RDN by Uta for the non-dyslexic students at
University College.
The question I ask is this.
If the Phonological processing is apparently
controlled by the visual image, which one is controlling the reading performance?
Anyone has any answers other than the obvious
one which I inferred?
