Why the study?
Does chronic social reward frustration alter brain activation patterns during reward omission in healthy adults?
Does chronic social reward frustration alter brain activation patterns during reward omission in healthy adults?
Chronic social reward frustration is associated with altered brain activation patterns in dopaminergic areas during reward omission, suggesting a compromised ability to adapt.
Altered prefrontal responses in susceptible adults should not yet change practice; hypothesis-generating for reward adaptation mechanisms, needing longitudinal data.
Neural correlates of reward frustration are increasingly studied in humans. In line with prediction error theory, omission of an expected reward is associated with relative decreases of cerebral activation in dopaminergic brain areas. We investigated whether a history of chronic work-related reward frustration influences this reward-dependent activation pattern by means of functional magnetic resonance imaging. Solving arithmetic tasks was followed by either monetary reward or omission of reward. Hyperactivations in the medial prefrontal, anterior cingulate and dorsolateral prefrontal cortex were observed in a group of healthy adults with high susceptibility to reward frustration as compared with a group with low susceptibility. Findings indicate a compromised ability of adapting brain activation among those suffering form chronic social reward frustration.
