The words are voiced again when they are processed and understood by the brain. The time between sight recognition and brain recognition is called lag time. Reducing lag time increases reading speed. Students may have to read many of the sentences two or more times to understand them. This is called regression.
Regression is reduced as reading speed increases.
The faster the individual reads, the less regression he or she will experience. Each student should be able to recognize his or her own reading level, and to distinguish between sight recognition and brain recognition. By knowing this, the student prevents superficial reading. If possible, students should do all of the exercises at the level of brain recognition. In other words, read by brain, not by sight.
