This research investigates the neurophysiological mechanisms of experiential versus monetary choices under risk. While ventral striatum and insula activity are instrumental in predicting monetary choices, we find that hippocampal activity plays a key role in predicting experiential choices, which we theorize is due to its role in retrieving autobiographical memories. This neurophysiological differentiation clarifies observed variations in risk preferences between experiential and monetary prospects and highlights the importance of domain-specific neurophysiological processes in shaping human decision-making.
本研究调查了风险情境下体验性选择与金钱选择的神经生理机制。虽然腹侧纹状体和脑岛活动有助于预测金钱选择,但我们发现海马体活动在预测体验性选择中起关键作用,我们推测这是由于其在检索自传体记忆中的作用。这种神经生理差异澄清了体验性和金钱前景之间观察到的风险偏好差异,并突出了特定领域神经生理过程在塑造人类决策中的重要性。
