some speed reading courses stress that the human eye has to move very quickly. they also stress that the human eye should move in a pattern to fill in the information that was not properly perceived. the effective limit for scanning speeds based upon the limit of the human eye's resolution is about 300 words per minute. it is claimed that such speeds also require great practice, and extremely rapid eye movements, although research suggests that such training is not possible. it has been suggested by some speed reading promoters that the readers who achieve such speeds are on the autism spectrum. research into reading rate suggests that study strategies, rather than speed reading, explains why expert readers, such as professors and editors, are more efficient than others.
