Delayed Matching to Sample (DMS)
Overview
Delayed Matching to Sample (DMS) assesses forced choice recognition memory for novel non-verbalisable patterns, and tests both simultaneous and short term visual memory. This test is primarily sensitive to damage in the medial temporal lobe area, with some input from the frontal lobes.
Administration Time
Around 10 minutes.
Task
The participant is shown a complex visual pattern (the sample) and then, after a brief delay, four similar patterns. The participant must touch the pattern which exactly matches the sample.
Outcome Measures
This test has nineteen outcome measures, assessing latency (the participant's speed of response), the numbers of correct patterns selected, and statistical analysis measuring the probabability of an error after a correct or incorrect response.
Test
Clinical mode (for testing once); five parallel modes (for repeated testing) and child mode (a simplified version for testing children)
