Watson, Poppy; Pavri, Yenti; Le, Jenny; Pearson, Daniel; Le Pelley, Mike E. – Learning & Memory, 2022
Attention, the mechanism that prioritizes stimuli in the environment for further processing, plays an important role in behavioral choice. In the present study, we investigated the automatic orienting of attention to cues that signal reward. Such attentional capture occurs despite negative consequences, and we investigated whether this…

Ramey, Michelle M.; Yonelinas, Andrew P.; Henderson, John M. – Learning & Memory, 2020
When we look at repeated scenes, we tend to visit similar regions each time--a phenomenon known as "resampling." Resampling has long been attributed to episodic memory, but the relationship between resampling and episodic memory has recently been found to be less consistent than assumed. A possibility that has yet to be fully considered…

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…

Nelson, James Byron; Craddock, Paul; Molet, Mikael; Renaux, Charlotte – Learning & Memory, 2017
One experiment determined the relationship between renewed associative strength and attention. Following cue1-outcome pairings in Context A, cue1 was extinguished in Context B while cue2 was conditioned. On test cue2 was chosen as a predictor of the outcome in Context B. Both cues were chosen equally often as predictors in Context A. Consistent…

Chudasama, Yogita; Dalley, Jeffrey W.; Nathwani, Falgyni; Bouger, Pascale; Robbins, Trevor W. – Learning & Memory, 2004
Two experiments examined the effects of reductions in cortical cholinergic function on performance of a novel task that allowed for the simultaneous assessment of attention to a visual stimulus and memory for that stimulus over a variable delay within the same test session. In the first experiment, infusions of the muscarinic receptor antagonist…

Vuckovich, Joseph A.; Semel, Mara E.; Baxter, Mark G. – Learning & Memory, 2004
A recent study suggests that lesions to all major areas of the cholinergic basal forebrain in the rat (medial septum, horizontal limb of the diagonal band of Broca, and nucleus basalis magnocellularis) impair a spatial working memory task. However, this experiment used a surgical technique that may have damaged cerebellar Purkinje cells. The…
