Striatal activation to monetary reward is associated with alcohol reward sensitivity [PDF]
Neuropsychopharmacology, 2020 One well-known phenotypic risk factor for the development of alcohol use disorder is sensitivity to the rewarding effects of alcohol. In the present study, we examined whether individuals who are sensitive to alcohol reward are also sensitive to nondrug rewards, thereby reflecting a broader individual difference risk factor. Specifically, we tested the

A Variational Formula for Risk-Sensitive Reward [PDF]
SIAM Journal on Control and Optimization, 2017 We derive a variational formula for the optimal growth rate of reward in the infinite horizon risk-sensitive control problem for discrete time Markov decision processes with compact metric state and action spaces, extending a formula of Donsker and Varadhan for the Perron-Frobenius eigenvalue of a positive operator. This leads to a concave maximization

Reward and Punishment Sensitivity in Children with ADHD: Validating the Sensitivity to Punishment and Sensitivity to Reward Questionnaire for Children (SPSRQ-C) [PDF]
Journal of Abnormal Child Psychology, 2011 This study validates the Sensitivity to Punishment and Sensitivity to Reward Questionnaire for children (SPSRQ-C), using a Dutch sample of 1234 children between 6-13 years old. Factor analysis determined that a 4-factor and a 5-factor solution were best fitting, explaining 41% and 50% of the variance respectively.

Neural activation to monetary reward is associated with amphetamine reward sensitivity [PDF]
Neuropsychopharmacology, 2018 One known risk factor for drug use and abuse is sensitivity to rewarding effects of drugs. It is not known whether this risk factor extends to sensitivity to non-drug rewards. In this study with healthy young adults, we examined the association between sensitivity to the subjective rewarding effects of amphetamine and a neural indicator of anticipation

The relationships among aberrant salience, reward motivation, and reward sensitivity [PDF]
International Journal of Methods in Psychiatric Research, 2018 AbstractObjectivesChange in reward processing and motivation may mediate the relationship between dopaminergic dysregulation and positive symptoms of schizophrenia. We sought to investigate the measurement of aberrant salience and its relationship with behavioural measures of reward and motivation.MethodsParticipants (n = 82) completed measures of ...

Adaptation of Reward Sensitivity in Orbitofrontal Neurons [PDF]
The Journal of Neuroscience, 2010 Animals depend on a large variety of rewards but their brains have a limited dynamic coding range. When rewards are uncertain, neuronal coding needs to cover a wide range of possible rewards. However, when reward is likely to occur within a specific range, focusing the sensitivity on the predicted range would optimize the discrimination of small reward

Contextual novelty changes reward representations in the striatum [PDF]
, 2010 Reward representation in ventral striatum is boosted by perceptual novelty, although the mechanism of this effect remains elusive. Animal studies indicate a functional loop (Lisman and Grace, 2005) that includes hippocampus, ventral striatum, and ...

Individual differences in reward-prediction-error: extraversion and feedback-related negativity [PDF]
, 2010 Medial frontal scalp-recorded negativity occurring ∼200–300 ms post-stimulus [known as feedback-related negativity (FRN)] is attenuated following unpredicted reward and potentiated following unpredicted non-reward.

Are pigs sensitive to variability in food rewards? [PDF]
Applied Animal Behaviour Science, 2008 Pigs are non-specialist feeders with high capacities to adapt their diets within wide limits to prevailing and unpredictable conditions. Under husbandry conditions however, pigs are usually fed under extremely predictable conditions, i.e. with highly uniform and standardized diets, ad libitum or at standardized times. Although pigs, in this way, obtain
