Rapid Visual Information Processing (RVP)
Overview
Rapid Visual Information Processing (RVP) is a test of sustained attention (similar to the Continuous Performance Task) and has proved useful in many studies in which drugs are used to help develop a disease model.. It is sensitive to dysfunction in the parietal and frontal lobe areas of the brain and is also a sensitive measure of general performance.
Administration Time
Around seven minutes.
Task
A white box appears in the centre of the computer screen, inside which digits, from 2 to 9, appear in a pseudo-random order, at the rate of 100 digits per minute. Participants are requested to detect target sequences of digits (for example, 2-4-6, 3-5-7, 4-6-8) and to register responses using the press pad.
Outcome Measures
The nine RVP outcome measures cover latency, probabilities and sensitivity (calculated using Signal Detection Theory), and hits, misses, false alarms and rejections.
Test
Clinical mode, plus 123 mode (for children aged 4-8) and 357 mode (for children aged 7-14).
