For appropriate control of behavior, organism have to choose their behavior for maximizing the volume of reward and minimizing the punishment. Many studies revealed that dopamine plays important role in reward processing, showed different tendency of performance in reward- and punishment-based reversal learning. The dopamine system is also known to be particularly vulnerable to aging. We examined reward- and punishment-related learning and transfer of learning to different task in older adults, investigating the effect of aging on positive or negative outcome processing. Participants were required to follow the instructed rule in Phase 1 to achieve associative knowledge between cue and outcome. In Phase 2, they performed the different task, where the cue used in Phase 1 signaled reward, punishment, or outcome probability without instructed rule. Through these experiments, the effect of aging on acquiring reward- and punishment-related knowledge and how these knowledge transfer to different situation were explored.
