Abstract
根据备择选项的信息是否完整,可以将决策分为描述性决策与经验性决策两个类别.随着年龄的增长,老年人在完成两类决策任务时的行为改变及其神经基础尚不明确.年轻人和老年人在fMRI扫描舱内分别完成了描述性和经验性决策任务.行为结果发现,相较于年轻人,老年人描述性决策能力保留而经验性决策能力受损,表现出决策能力改变的不对称性.神经影像学证据显示,在两种决策任务中老年人均表现出决策相关脑区的过度激活,但是这种过度激活更多是在描述性决策中起到了补偿作用,揭示了老年人决策能力改变不对称性的潜在神经基础.研究结果提示年老化对决策行为和神经活动均产生影响,相较于描述性决策老年人经验性决策能力更容易受到增龄的影响,研究结果对老年人群的决策干预提供了方向.</p
