Sign Up to like & getrecommendations! Published in 2017 at "JAMA Psychiatry"
DOI: 10.1001/jamapsychiatry.2016.3084
Abstract: Importance Disrupted reward processing, mainly driven by striatal dysfunction, is a key characteristic of addictive behaviors. However, functional magnetic resonance imaging (fMRI) studies have reported conflicting results, with both hypoactivations and hyperactivations during anticipation and… read more here.

Striatal responsiveness to reward under threat‐of‐shock and working memory load: A preliminary study
Sign Up to like & getrecommendations! Published in 2019 at "Brain and Behavior"
DOI: 10.1002/brb3.1397
Abstract: Reward and stress are important determinants of motivated behaviors. Striatal regions play a crucial role in both motivation and hedonic processes. So far, little is known on how cognitive effort interacts with stress to modulate… read more here.

DOI: 10.1002/brb3.807
Abstract: Empathy and shared feelings of reward motivate individuals to share resources with others when material gain is not at stake. Behavioral variant frontotemporal dementia (bvFTD) is a neurodegenerative disease that affects emotion‐ and reward‐relevant neural… read more here.

DOI: 10.1002/dev.22026
Abstract: The Adaptive Calibration Model of Stress Responsivity (ACM) suggests that developmental experiences predictably tune biological systems to meet the demands of the environment. Particularly important is the calibration of reward systems. Using a longitudinal sample… read more here.

DOI: 10.1002/jeab.838
Abstract: Detection dogs have demonstrated reduced performance in operational settings when required to search in an environment where few to no target odors are present. This study's purpose was to increase detection dog accuracy using noncontingent… read more here.

DOI: 10.1002/jnr.25025
Abstract: Encoding of memories, including those associated with prior drug or reward, is thought to take place within distinct populations of neurons, termed ensembles. Neuronal ensembles for drug‐ and reward‐seeking have been identified in regions of… read more here.

DOI: 10.1002/sres.2444
Abstract: We examine how the performance of teams and of the individuals within them varies with disparity in team member ability and with the reward structure in place. We carry out an experiment on a sample… read more here.

DOI: 10.1007/s00265-017-2328-y
Abstract: The associative learning of spatial and reward information is generally considered an adaptive behavior of foraging animals that collect food from renewable resources. However, learning may not always maximize foraging efficiency if choosing a high-reward… read more here.

DOI: 10.1007/s00426-017-0966-3
Abstract: Brain and behavior evidence suggests that colors have distinct affective properties. Here, we investigated how reward influences color-driven affect in perception. In Experiment 1, we assessed competition between blue and red patches during a temporal-order… read more here.
