Relevance and uncertainty jointly influence reward anticipation at the level of the SPN ERP component
The stimulus-preceding negativity (SPN) component reflects the anticipatory phase of
reward processing. Its amplitude is usually larger for informative compared to uninformative
upcoming stimuli, as well as for uncertain relative to predictable ones. In this study, we
sought to assess whether these two effects, when combined together, produced a
synergistic effect or rather independent ones on the SPN during performance monitoring.
Participants performed a speeded Go/NoGo task while 64-channel EEG was recorded …
