On the development and mechanics of delayed matching-to-sample performance. [PDF]
J Exp Anal Behav, 2011 Despite its frequent use to assess effects of environmental and pharmacological variables on short-term memory, little is known about the development of delayed matching-to-sample (DMTS) performance. This study was designed to examine the dimensions and dynamics of DMTS performance development over a long period of exposure to provide a more secure ...

CHARACTERISTICS OF FORGETTING FUNCTIONS IN DELAYED MATCHING TO SAMPLE [PDF]
Journal of the Experimental Analysis of Behavior, 1985 Performance of pigeons in delayed matching‐to‐sample procedures was measured in terms of an index of discriminability derived from the difference between logarithms of ratios of choice responses to comparison stimuli following the different sample stimuli.

GENERALIZATION OF DELAYED MATCHING TO SAMPLE FOLLOWING TRAINING AT DIFFERENT DELAYS [PDF]
Journal of the Experimental Analysis of Behavior, 2001 Four groups of pigeons were trained to perform a delayed matching‐to‐sample task with a single delay of 0, 2, 4, or 6 s from the outset of training. The longer the training delay, the more sessions were required for all birds to reach the same level of response accuracy.

Reversing the signaled magnitude effect in delayed matching to sample: delay-specific remembering. [PDF]
J Exp Anal Behav, 2011 Pigeons performed a delayed matching‐to‐sample task in which large or small reinforcers for correct remembering were signaled during the retention interval. Accuracy was low when small reinforcers were signaled, and high when large reinforcers were signaled (the signaled magnitude effect).

CHOICE AS A FUNCTION OF REINFORCEMENT RATIOS IN DELAYED MATCHING TO SAMPLE [PDF]
Journal of the Experimental Analysis of Behavior, 1996 Pigeons were studied in two experiments using a delayed matching‐to‐sample task. In Experiment 1, 4 subjects were exposed to a task in which the proportion of reinforcement associated with matching and nonmatching, and the overall proportion of reinforcement associated with selecting each choice, regardless of the sample stimulus, were varied.

CANTAB delayed matching to sample task performance in juvenile baboons. [PDF]
J Neurosci Methods, 2011 This study reports the administration of the Cambridge Neuropsychological Test Automated Battery system's delayed matching to sample (DMTS) task to juvenile baboons. Nine subjects (female=5, male=4) were trained with delay intervals ranging from 0 to 80s.

A theory of attending, remembering, and reinforcement in delayed matching to sample. [PDF]
J Exp Anal Behav, 2007 A theory of attending and reinforcement in conditional discriminations (Nevin, Davison, & Shahan, 2005) is extended to working memory in delayed matching to sample by adding terms for disruption of attending during the retention interval. Like its predecessor, the theory assumes that reinforcers and disruptors affect the independent probabilities ...

ASSESSING CONTROL BY ELEMENTS OF COMPLEX STIMULI IN DELAYED MATCHING TO SAMPLE [PDF]
Journal of the Experimental Analysis of Behavior, 1993 A series of six experiments examined delayed identity matching‐to‐sample performances of subjects with mental retardation. The stimuli were either one or two simultaneously displayed forms. When the reinforcement contingencies required that only one form exert discriminative control, all subjects achieved high accuracy scores.

TITRATING‐DELAY MATCHING‐TO‐SAMPLE IN THE PIGEON [PDF]
Journal of the Experimental Analysis of Behavior, 2010 The titrating‐delay matching‐to‐sample (TDMTS) procedure offers researchers an additional behavioral task thought to capture some important features of remembering. In this procedure, the delay between sample offset and comparison onset adjusts as a function of the subject's performance.

Disruption of delayed matching to sample [PDF]
Bulletin of the Psychonomic Society, 1981 Two pigeons were exposed to a 3-sec delayed matching-to-sample (DMTS) procedure. Following acquisition, reinforcement for sample responding was presented during the delay interval. After baseline recovery, a blackout procedure was instituted during the delay interval. Both procedures reduced the accuracy of responding on the DMTS task.
