Sensation seeking strongly predicts diverse risk-taking behaviors, potentially linked to altered neural reward processing. However, it remains unexplored how this reward processing is modulated by uncertainty context. We recorded EEG from 41 high sensation seekers (HSS) and 40 low sensation seekers (LSS) when they anticipated and experienced monetary rewards in risky (known outcome probabilities) and ambiguous (unknown outcome probabilities) contexts. Our results showed that during cue evaluation, HSS exhibited a blunted cue-P3 differentiation between risk and ambiguity compared to LSS. During...
