Sign Up to like & getrecommendations! Published in 2017 at "Current Neurology and Neuroscience Reports"
DOI: 10.1007/s11910-017-0755-9
Abstract: Purpose of ReviewSurprises are important sources of learning. Cognitive scientists often refer to surprises as “reward prediction errors,” a parameter that captures discrepancies between expectations and actual outcomes. Here, we integrate neurophysiological and functional magnetic… read more here.

DOI: 10.1016/j.cortex.2017.09.017
Abstract: Prediction errors are deemed necessary for the updating of internal models of the environment, prompting us to stop or assert current action plans and helping us to adapt to environmental features. The aim of the… read more here.

DOI: 10.1016/j.neuroimage.2019.02.052
Abstract: &NA; Most studies that have investigated the brain mechanisms underlying learning have focused on the ability to learn simple stimulus‐response associations. However, in everyday life, outcomes are often obtained through complex behavioral patterns involving a… read more here.

DOI: 10.1038/s41598-019-43474-2
Abstract: Activity changes in dopaminergic neurons encode the ongoing discrepancy between expected and actual value of a stimulus, providing a teaching signal for a reward prediction process. Previous work comparing a cohort of long-term Zen meditators… read more here.

DOI: 10.1038/s41598-021-99408-4
Abstract: Reinforcement learning in humans and other animals is driven by reward prediction errors: deviations between the amount of reward or punishment initially expected and that which is obtained. Temporal difference methods of reinforcement learning generate… read more here.

DOI: 10.1073/pnas.2113311119
Abstract: Significance Recent studies have confirmed the role of dopamine firing in reward prediction error, even under perceptual uncertainty. However, little is known about dopamine behavior during the use of working memory or its role in… read more here.

DOI: 10.1093/scan/nsz089
Abstract: Abstract Extensive literature shows that alexithymia, a subclinical trait defined by difficulties in identifying and describing feelings, is characterized by multifaceted impairments in processing emotional stimuli. Nevertheless, its underlying mechanisms remain elusive. Here, we hypothesize… read more here.

DOI: 10.1146/annurev-neuro-072116-031109
Abstract: Dopamine neurons facilitate learning by calculating reward prediction error, or the difference between expected and actual reward. Despite two decades of research, it remains unclear how dopamine neurons make this calculation. Here we review studies… read more here.

DOI: 10.1371/journal.pone.0189212
Abstract: Reward prediction errors (RPEs) are thought to drive learning. This has been established in procedural learning (e.g., classical and operant conditioning). However, empirical evidence on whether RPEs drive declarative learning–a quintessentially human form of learning–remains… read more here.
