Rapid Serial Visual Presentation
Rapid Serial Visual Presentation ( RSVP ) is an experimental paradigm in cognitive science .
Experimental paradigm
RSVP is used in experiments, including studies on language processing, to present a text, usually individual sentences, to test subjects. The test participants are usually expected to react after a certain event and the average time until this reaction is determined. The events can, for example, be errors in the sentence ("Anomaly Detection") or tones.
It also shows streams of letters, for example one letter for 10 milliseconds, in which digits are embedded. The aim of the test subjects in this case is to recognize these “targets” in the stream and then to carry out various tasks. These tasks range from simply naming the target, to naming the next few stimuli following the target, to naming other targets in the stream. These experiments often occur in investigations of the attentional blink .
Application in software technology
On small displays, such as a cell phone or handheld, RSVP is used as a presentation technique to display longer texts. Instead of displaying the text in a static and paper-like manner, in page form, the text is played dynamically on the display. The user does not scroll himself, but just follows the words on the display. The speed is calculated adaptively, taking into account the text structure. Punctuations slow them down, shorter words accelerate them.
