Reversal Learning
Research News and Information
Definition of 'Reversal Learning'Any situation where an animal or human is trained to respond differentially to two stimuli (e.g., approach and avoidance) under reward and punishment conditions and subsequently trained under reversed reward values (i.e., the approach which was previously rewarded is punished and vice versa). Common names: Reversal Learning; Learning, Reversal; Learnings, Reversal; Reversal Learnings |

Double dissociation and hierarchical organization of strategy switches and reversals in the rat PFC.
29 Sep 2009
Prelimbic-infralimbic cortex (PL-IL) and orbitofrontal cortex (OFC) influence behavioral flexibility in the rat. The authors tested the effects of PL-IL or OFC infusion with the GABA agonist muscimol in the context of 2 flexible responding tasks: ... Read more...

Local availability of glycine near N-methyl-D-aspartate receptors (NMDARs) is partly regulated by neuronal glycine transporter 1 (GlyT1), which can therefore modulate NMDAR function because binding to the glycine site of the NMDAR is necessary for ... Read more...
The time course of task switching: a speed--accuracy trade-off analysis.
29 Sep 2009
On each trial of this study, participants either switched between or repeated two simple, two-choice tasks involving either letter or digit classifications. Speed-accuracy trade-off (SAT) curves were obtained using the response-signal method of ... Read more...
