Hi Stuart, The statistic was explained earlier. Two groups of people were given a text to read. One text was in printed form; the other was read online. Both groups were then given a set of questions about the text they had read (the same set of questions). When repeated many times, the results was this: those who read the printed text got more questions right. The difference between the groups was 60%.

Sorry folks, pressed Send by mistake. I was going to finish off by saying: My feeling is that comprehension is a factor (of course), reader preferences are a factor (of course), the environment is a factor, the nature of the text or task is a factor... So "always"? No. "reader preferences carry the day: yes or no?" Maybe? Sometimes? It depends? My main reservation about this thread is that I don't know how much weight to put on the comprehension studies you cite. "Up to 60%" isn't a statistic I can do anything with. What does it mean? - every subject's comprehension was worse and the worst of the lot was 60% worse - some were worse, some were better, but on average more were worse - results varied depending on the material, and for a particular sort of material the readers' (reader's?) comprehension was 60% worse Stuart
