Reward processing is a research area within psychology and neuroscience that focuses on how the brain responds to and processes rewards. This includes studying how rewards influence behavior, decision-making, motivation, and learning. Researchers in this field investigate the neural mechanisms involved in processing rewards, such as the role of neurotransmitters like dopamine, and how individual differences in reward processing may contribute to various psychological disorders and conditions. The goal of this research is to gain a better understanding of how rewards impact human behavior and well-being.
