行为和神经影像学研究表明,与年轻人相比,老年人对经济损失的敏感度较低。然而,人们对社会决策和社会奖励处理中与年龄相关的差异知之甚少。作为试点研究的一部分,我们收集了 50 名参与者(年轻:N = 26,年龄 18-34 岁;年长:N = 24,年龄 63-80 岁)的行为和功能磁共振成像 (fMRI) 数据,他们在扫描仪中完成了三项任务:作为投资者的经济信任游戏,与作为投资对象的三个合作伙伴(计算机、陌生人、朋友)进行经济信任游戏;以及与三个伙伴(计算机、陌生人、朋友)分享金钱收益和损失的猜牌任务;以及作为对三个匿名提议者(计算机、年龄相似的成年人、年龄不同的成年人)的响应者的最后通牒游戏。我们还收集了 B0 场图和高分辨率结构图像(T1 加权和 T2 加权图像)。这些数据可以重复使用来回答有关功能磁共振成像信号的瞬时变化、任务之间的表征相似性和大脑结构的问题。
Behavioural and neuroimaging research has shown that older adults are less sensitive to financial losses compared to younger adults. Yet relatively less is known about age-related differences in social decisions and social reward processing. As part of a pilot study, we collected behavioural and functional magnetic resonance imaging (fMRI) data from 50 participants (Younger: N = 26, ages 18–34 years; Older: N = 24, ages 63–80 years) who completed three tasks in the scanner: an economic trust game as the investor with three partners (computer, stranger, friend) as the investee; a card-guessing task with monetary gains and losses shared with three partners (computer, stranger, friend); and an ultimatum game as responder to three anonymous proposers (computer, age-similar adults, age-dissimilar adults). We also collected B0 field maps and high-resolution structural images (T1-weighted and T2-weighted images). These data could be reused to answer questions about moment-to-moment variability in fMRI signal, representational similarity between tasks, and brain structure.
