Along with other strategies, you can read for longer periods. The third pitfall has to do with pronouncing the words in our head, or sub-vocalization. This is a limitation because we cannot read and comprehend well much faster that we can talk. Top speed for human speech is about 265 to 285 words per minute. By reading four or five words at a glance, our brain gives up on trying to say the words, and simply gives us the meaning without the pronunciation.
Comprehension goes up.
As our speed goes up, so does our comprehension. This would seem to defy logic, but only with your present tools. When you can see and understand five words at a time, you engage your right brain which is capable of tremendous understanding. The fourth pitfall is poor vocabulary. The fifth and final pitfall to overcome is poor organization.
