I've reading a book about dyslexia, which is proving quite fascinating.
Anyway it's thrown up this question for me and, as I've only one son around at the moment to ask, I'm asking MN.
What you hear when you read - if you hear anything - your voice, another voice, a mixture of voices; ate they different accents?
Also what do you see - if anything - does the image form as you read the sentence or do you think it after you've finished.
I hear my own voice for all words and only form images occasionally (if I'm trying to figure out text and I've just realised I pause reading to do so).
My son hears his own voice and pictures images for all words that have a possible image as he reads them (the picture comes together as he reads the sentence.)
So for the sentence:
The black swan silently glided across the lake.
I read it using my voice internally and picture it after. (All takes less than a second, so feels like it might be at the same time.)
DS hears each word in his voice but pictures them as he reads so nothing for 'The', sees black for 'black' and this forms into a black swan on reading swan, etc. (Again all done quickly. Not as slow as it might come across when described!!)
