This is a test of visual spatial recognition memory in a 2-choice forced discrimination paradigm. This test is often used, in conjunction with Pattern Recognition Memory (PRM) , before the Paired Associates Learning (PAL) test, as both these tests help to train the subject for PAL.
PRM and SRM contain different elements of PAL and the results considered together help to decide on the exact nature of the cognitive deficit being considered. |
Administration time
Around 5 minutes, depending on level of impairment
Task
The subject is presented with a white square, which appears in sequence at five different locations on the screen. In the recognition phase, the subject sees a series of five pairs of squares, one of which is in a place previously seen in the presentation phase. The other square is in a location not seen in the presentation phase. As with the PRM test, locations are tested in the reverse of the presentation order. This sub-test is repeated three more times, each time with five new locations
Test modes
Clinical mode (for testing once); four parallel modes (for repeated testing).
Outcome measures
This test has three outcome measures, including the number and percentage of correct trials and latency (speed of subject’s response).
