Animal memory: A review of delayed matching-to-sample data
Behavioural Processes, 2015We performed a meta-analysis of over 90 data sets from delayed matching-to-sample (DMTS) studies with 25 species (birds, mammals, and bees). In DMTS, a sample stimulus is first presented and then removed. After a delay, two (or more) comparison stimuli are presented, and the subject is rewarded for choosing the one matching the sample.

Ambiguous stimuli and delayed matching to sample
Behavioural Processes, 1992Four 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.

Delayed matching to sample in pigeons: Effects of delay of reinforcement and illuminated delays
Learning and Motivation, 2015Abstract Pigeons show relatively poor memory when trained on 0-s delayed matching and tested with longer delays. We hypothesized that one reason for the effect of delay may be a loss of association between sample responding and reinforcement. To test this hypothesis, we compared the effect of standard delays inserted between the offset of the sample ...

A Chaining Analogue to Delayed Matching to Sample
The Psychological Record, 1980Pigeons were trained on an analogue to a delayed matching-to-sample procedure requiring explicit, sample-specific, mediating responses during the delay. Each trial consisted of a three-link chain. The first and third links of the chain were the sample and choice components respectively of matching to sample.

Acquisition under Mixed-Delay and Multiple-Delay Matching-to-Sample
Psychological Reports, 1973The acquisition of delayed matching to sample in two groups of pigeons was examined when three delay values (2, 4, and 6 sec.) were mixed across trials and when each of the three delay values was correlated with one of three standard stimuli (i.e., multiple delays).

Nicotine enhances delayed matching-to-sample performance by primates
Life Sciences, 1988The 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.

Conditional Versus Trial-Unique Delayed Matching-to-Sample
American Journal on Mental Retardation, 1998We 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.

Comparison of delayed matching-to-sample performance in monkeys and children
Behavioural Processes, 2014Although research has consistently demonstrated that accuracy on a variety of memory tasks decreases as delay increases, relatively little research has been conducted to quantify this relationship across development in humans or directly compare rates of forgetting between humans and monkeys. This study utilized a delayed matching-to-sample (DMTS) task
