Pattern Recognition Memory (PRM)

Pattern Recognition Memory is a test of visual pattern recognition memory in a 2-choice forced discrimination paradigm.

Administration time

4 minutes

Task format

The participant is presented with a series of visual patterns, one at a time, in the centre of the screen. These patterns are designed so that they cannot easily be given verbal labels. In the recognition phase, the participant is required to choose between a pattern they have already seen and a novel pattern. In this phase, the test patterns are presented in the reverse order to the original order of presentation. This is then repeated, with new patterns. The second recognition phase can be given either immediately or after a delay.

Outcome measures

Outcome measures include the number and percentage of correct trials and latency (speed of participant’s response).
