A MRI expert tells me:
"Speaking of screening, when you call for MRI tests to investigate its difference from reading, isn't that a form of screening, too, privileging an image on an electronic display? The test I would suggest is not telling subjects the real purpose of the experiment, letting some read and comment on a text displayed in a printed book OR on a PC screen OR on a reader (e-ink or TFT), and then let raters also unaware of the real purpose look for differences in what people write after different modes. "
I agree. Let the tests begin!
