Understanding how humans process feedback, predictions, and prediction errors, as well as their relationship to reinforcement magnitude, is crucial both for elucidating the mechanisms driving human economic behavior and for informing the development of new models of neuroplasticity and learning-related brain reorganization. The aim of our study was to investigate learning-associated plastic changes by examining alterations in evoked potentials in response to auditory cues during one of the most used empirical trials in neuroeconomics - monetary incentive delay (MID) task. Our findings demonstrate that associating a previously neutral auditory stimulus with a specific monetary loss can induce plastic changes manifesting as context-dependent enhancement of auditory evoked potential amplitudes. These results contribute to existing models of learning and decision-making and add to our understanding of the neural mechanisms underlying reinforcement learning.
