Kikas, Katarina; Westbrook, R. Frederick; Holmes, Nathan M. – Learning & Memory, 2021
Four experiments examined the effects of a dangerous context and a systemic epinephrine injection on sensory preconditioning in rats. In each experiment, rats were exposed to presentations of a tone and light in stage 1, light-shock pairings in stage 2, and test presentations of the tone alone and light alone in stage 3. Presentations of the tone…

Forrest, Charlotte L. D.; Monsell, Stephen; McLaren, Ian P. L. – Journal of Experimental Psychology: Learning, Memory, and Cognition, 2014
Task-cuing experiments are usually intended to explore control of task set. But when small stimulus sets are used, they plausibly afford learning of the response associated with a combination of cue and stimulus, without reference to tasks. In 3 experiments we presented the typical trials of a task-cuing experiment: a cue (colored shape) followed,…

Andreau, Jorge Mario; Funahashi, Shintaro – Brain and Cognition, 2011
The prefrontal cortex (PFC) is known to contribute to memory processes such as encoding representations into long-term-memory (LTM) and retrieving these representations from LTM. However, the details of the PFC's contribution to LTM processes are not well known. To examine the characteristics of the PFC's contribution to LTM processes, we analyzed…

Urcuioli, Peter J. – Journal of the Experimental Analysis of Behavior, 2008
Five experiments assessed associative symmetry in pigeons. In Experiments 1A, 1B and 2, pigeons learned two-alternative symbolic matching with identical sample- and comparison-response requirements and with matching stimuli appearing in all possible locations. Despite controlling for the nature of the functional stimuli and insuring all requisite…

Frank, Andrea J.; Wasserman, Edward A. – Journal of the Experimental Analysis of Behavior, 2005
If an organism is explicitly taught an A[arrow right]B association, then might it also spontaneously learn the symmetrical B[arrow right]A association? Little evidence attests to such "associative symmetry" in nonhuman animals. We report for the first time a clear case of associative symmetry in the pigeon. Experiment 1 used a successive go/no go…

Sambeth, A.; Maes, J. H. R. – Learning and Motivation, 2006
The purpose of this experiment was to compare components of the human and rat auditory event-related potential (ERP) in a serial feature-positive discrimination task. Subjects learned to respond to an auditory target stimulus when it followed a visual feature (X [right arrow] A+), but to not respond when it was presented alone (A-). Upon solving…
