Rapid serial visual presentation (RSVP) is a scientific method for studying the timing of vision. In RSVP, a sequence of stimuli are shown to an observer at one location in their visual field. The observer is instructed to report one of these stimuli - the target - which has a feature that differentiates it from the rest of the stream. For instance, observers may see words which have all grey letters with the exception of one red letter. They are told to report the red letter. People make errors in this task in the form of reports of stimuli that occurred before or after the target. The position in time of the letter they report, relative to the target, is an estimate of the timing of visual selection on that trial.
Speed Reading
Rapid serial visual presentation (RSVP) is also a type of reading where instead of moving your vision across the page, words are presented one after the other in the same spot. Because your iris does not have to move the theory is that you are able to read much faster with this method than you would be able to with a traditional book. Many people may read in the 250-300 words per minute range, but with RSVP they may be able to read up to 400 words per minute. With a little practice, you can push your reading speed quite a bit higher with RSVP while retaining reasonably good comprehension. While the speed of reading almost certainly can increase, the problem with this form of reading is that the observer must fix their vision at one point on a screen. This may not be a good thing for the eyes if over done.

Peripheral reading
Peripheral reading is vital to those suffering from central field loss, which is most commonly seen in the elderly. Factors which might limit one's peripheral reading rate include acuity, crowding, and eye movements. Many find difficulty making the correct eye movements for peripheral reading, but the dependence on eye movements can be minimized through the presentation format of RSVP.[1]
