Lynn Poole discusses reading comprehension and speed and how bad habits, such as moving one's mouth while reading, can be eliminated. He also shows a regressive reader, who lacks concentration and doesn't trust her comprehension. An ophthalmograph, which records every eye movement on film, is demonstrated along with the eye graphs of efficient and poor readers. A film, prepared by W. G. Perry, Jr. and C. P. Whitlock of Harvard University, simulates a reading clinic's tachistoscope, developed by Samuel Renshaw, to improve a student's precision of vision (length of time focused on a word and number of words in eye fixation) and peripheral vision. Dr. Milton S. Eisenhower, president of Johns Hopkins University, points out that the objective of all college courses is to increase reading, writing, listening, and speaking skills. However, in 1955, only 17% of all U. S. adults were regularly reading books, and there was a disparity between reading levels and chronological ages.
