Ambiguous stimuli and delayed matching to sample

Behavioural Processes, 1992
Four pigeons learned a delayed matching task in which the sample and choice stimuli were line orientations. After performance had reached a high level of accuracy the procedure was altered so that only one of the line choice stimuli was presented on each trial and a uniform white field was presented on the other key.

Conditional Versus Trial-Unique Delayed Matching-to-Sample

American Journal on Mental Retardation, 1998
We compared performance on conditional and trial-unique delayed identity matching-to-sample procedures. In Experiment 1, participants with moderate to severe mental retardation were exposed to both procedures under a single, brief delay value. Three of 5 subjects showed higher accuracy in the trial-unique sessions.

Nicotine enhances delayed matching-to-sample performance by primates

Life Sciences, 1988
The non-human primate provides an excellent model for studies of learning and memory, and one particular test, the delayed matching-to-sample task, is performed in a similar manner by both humans and non-human primates. Five young adult macaques were employed in this study, displaying variable capacities for retention in the task.
