| 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. Subjects 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.
Test modes
Clinical mode, plus 123 mode (for children aged 4-8) and 357 mode (for children aged 7-14).
Outcome measures
The nine RVP outcome measures cover latency, probabilities and sensitivity (calculated using Signal Detection Theory), and hits, misses, false alarms and rejections.
