Since I read a lot, also aloud, interpunction is important, and while not covered by name, upper case is part of it. Usually it is at least a word, but speed read record holders can read whole page at once. Lower case is simply smaller, so I can take more words with a glance (again, I've been tested with capacity of reading 3-4 words at once, depending on their length).īasically, reading at any sensible speed requires reading more than one letter at once. I myself am a fast reader (moderately: I've been clocked at bit over 1200 words per minute), so most of what's below is from experience. This has to do with reading speed, familiarity, shape and eye movement. There is definitely qualitative and quantitative difference between upper case and lower case reading experience. Not in the sence of recognition of words and as such has no effect on readability (provided that font weight and contrast is the same). So it really doesn't matter if the letters are all caps or not. The research strongly suggests that you recognize all the letters in a word at the same time, and then you use the recognition of those letters to recognize the word. You don’t recognize words by the shape of the word. There was some evidence for it, but more recent research shows that it is letters you are recognizing and anticipating. It’s parallel letter recognition, not word shape - The old theory on word shapes comes from a psycholinguist named Cattell who came up with that theory in 1886. D Susan Weinschenk informed the community in her article 100 Things You Should Know About People: #19 - It’s a Myth That All Capital Letters Are Inherently Harder to Read that the shape theory is wrong: It was common knowledge that humans read words as a shape until Ph.
