If a student is a slow reader, he has little time for other activities. Since most fast readers read continuously at the lower subconscious, they can process new concepts and ideas at the subconscious level without much trouble. This is possible because the sentences or concepts are read as a complete unit rather than as a group of words. When a person reads at this level, he is speed-reading. The words and their concepts are processed together, like watching a movie.
Slow readers tend to process one word at a time.
