White, K. Geoffrey; Wixted, John T. – Journal of the Experimental Analysis of Behavior, 2010
Delayed matching to sample is typically a two-alternative forced-choice procedure with two sample stimuli. In this task the effects of varying the probability of reinforcers for correct choices and the resulting receiver operating characteristic are symmetrical. A version of the task where a sample is present on some trials and absent on others is…

Eichenbaum, Howard; Fortin, Norbert J. – Journal of the Experimental Analysis of Behavior, 2005
The notion that non-human animals are capable of episodic memory is highly controversial. Here, we review recent behavioral work from our laboratory showing that the fundamental features of episodic memory can be observed in rats and that, as in humans, this capacity relies on the hippocampus. We also discuss electrophysiological evidence, from…

Odum, Amy L.; Shahan, Timothy A.; Nevin, John A. – Journal of the Experimental Analysis of Behavior, 2005
This experiment examined the effects of reinforcement probability on resistance to change of remembering and response rate. Pigeons responded on a two- component multiple schedule in which completion of a variable-interval 20-s schedule produced delayed matching-to-sample trials in both components. Each session included four delays (0.1 s, 2 s, 4…
