    Abstract: Examined the assumption that monetary incentives always result in increased performance. Human decision makers frequently focus on past performance, a form of reinforcement learning occasionally at odds with rational decision making. An incentivized belief-updating task from economics was employed to investigate this conflict through measurements of neural correlates of reward processing. 85 healthy college students (aged 19-29 years) participated in 2 experiments while electroencephalography (EEG) was recorded. Results showed that higher incentives fail to improve performance when immediate feedback on decision outcomes is provided. Subsequent analysis of the feedback-related negativity, an early event-related potential following feedback, revealed the mechanism behind this paradoxical effect. As incentives increase, the win/lose feedback becomes more prominent, leading to an increased reliance on reinforcement and more errors. This mechanism is relevant for economic decision making and the debate on performance-based payment. zitiert von 15
