Today I practised reading with the index finger. The goal is to eliminate regressions.
Regressions may be of two types: intentional and unintentional. Whereas the former is a result of a conscious re-reading of what has been read, the latter is a waste.
The latter can be divided into two groups: movement of eyes from the end of a line to the beginning of the next line and movements inside a line.
Reading with the index finger is against these movements inside a line. You are simply following the finger and eyes never go back until the end of line. The speed at the finger is moved also helps you read faster. My speed this time was 235-240 WPM. Do you feel the difference? As much as twice, the method definitely works.
