What is a delayed match to sample test?
Delayed Matching to Sample assesses both simultaneous visual matching ability and short-term visual recognition memory, for non-verbalisable patterns. The participant is shown a complex visual pattern, that is both abstract and non-verbal (the sample), followed by four similar patterns, after a brief delay.
Will be delayed meaning?
Verb. delay, retard, slow, slacken, detain mean to cause to be late or behind in movement or progress. delay implies a holding back, usually by interference, from completion or arrival.

What is a sample stimulus?
a procedure for increasing the generalizability of research results by using multiple stimuli within a category as representative of an experimental condition, as opposed to selecting a single stimulus whose unique characteristics may distort results.
What is the delayed nonmatch to sample task?
Another developmental task that tests for explicit learning and memory is the delayed nonmatch to sample (DNMS) task. The DNMS task requires the subject to compare a presented sample object with a previously presented comparison object and encourages the selection of a novel object with an object’s second presentation.
How does delayed matching to sample ( DMS ) work?
Delayed Matching to Sample (DMS) Delayed Matching to Sample assesses both simultaneous visual matching ability and short-term visual recognition memory, for non-verbalisable patterns.
How is short term memory used in match to sample task?
Short-term memory for learned associations has been studied using the match-to-sample task (and the related delayed match-to-sample task, and non-match to sample task ).
Is there a delay between the sample and the choice pattern?
In some trials the sample and the choice patterns are shown simultaneously, in others there is a delay (of 0, 4 or 12 seconds) before the four choices appear.
