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 |

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...
29 Sep 2009
Recent task-switching studies in which a predictable task sequence has been used have indicated that verbal representation contributes to the control of task order information. The present study focused on the role of verbal representation in ... Read more...
Distinct hippocampal and basal ganglia contributions to probabilistic learning and reversal.
30 Aug 2009
The hippocampus and the basal ganglia are thought to play fundamental and distinct roles in learning and memory, supporting two dissociable memory systems. Interestingly, however, the hippocampus and the basal ganglia have each, separately, been ... Read more...
