Rapid Visual Information Processing (RVP)

Rapid Visual Information Processing is a measure of sustained attention.

Administration time

7 minutes

Task format

A white box is shown in the centre of the 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). When the participant sees the target sequence they must respond by selecting the button in the centre of the screen as quickly as possible. The level of difficulty varies with either one- or three-target sequences that the participant must watch for at the same time.  

Outcome measures

Outcome measures cover latency (speed of response), probability of false alarms and sensitivity.
