This study, involving 47 students in grades 2-10, investigated letter-naming speed to determine whether it measures cognitive speed, a theoretical factor that purportedly influences reading rate. It was determined that cognitive speed and cognitive power are two independent factors and that letter-naming speed can be used to measure cognitive…

This is the final report on a research project that measured the effect of reading rate on accuracy and the efficiency of reading comprehension. At the outset of the project, existing research data were integrated into a comprehensive account called a "rauding theory," which interrelates reading ability, passage difficulty, reading time,…
