'aulacity' has me beat presented in isolation. If it's meant to be 'actuality' then it's spelled wrong...
It's not 'actuality', it's 'actually'. You mistook an L for an I. This is what can happen when you try to read each word and your eyesight lets you down, or there is a blot of some sort on your screen or your page.
The point is that the words are not presented in isolation when we read a text, and it is possible to figure them out partly based on context, which allows us to anticipate.
MaizieD, All the research on eye movement suggests very strongly that reading each and every word left to right, taking cognisance of each letter, which you claim to do when you read, simply does not happen, except when readers are at a very basic stage of learning to read. Once reading aloud with correct intonation begins, this stage is left behind.
Again, as I said when I C&P'd the piece, there was no actual research. It was a meme that did the rounds on the net.
