项目摘要

DESCRIPTION (provided by applicant): This project proposes a series of experiments that will contribute to the burgeoning field of the neuroeconomics of aging, which attempts understand the component processes of decision-making across the lifespan by examining both behavior and the underlying neural substrates. The proposed studies seek to begin specifying the mechanisms of decisions, in particular the deliberative and affective components that make up the decision-making process. Affective influences on decision-making have been largely ignored for many years, but recent interest in how our emotional states can affect the type of decisions we make offer an exciting opportunity to broaden our knowledge of this most important process. Further, examining the degree to which affective and deliberative processing differentially influence decision-making across the lifespan can provide important clues for the assessment of these basic cognitive functions. Specifically, the proposed experiments will use functional magnetic resonance imaging (fMRI) to measure brain function of people engaged in economic decision-making. This proposal builds on previous work by the author examining the processes underlying human decision-making in a consequential social interaction with another person. These studies have found reliable, independent patterns of neural activity corresponding to affective and deliberative biases, and shown that subsequent decisions appear to be based on these different motives. In the present proposal, hypotheses generated in this previous study will be systematically tested. Experiments using fMRI and variants of Ultimatum and Trust Games will explore in greater depth the degree to which affective and deliberative processes influence decisions in both young and older populations. The field of neuroeconomics is growing rapidly as researchers from many different and disparate areas seek to understand the neural basis of human decision-making behavior. It allows the study of individuals in meaningful social interactions allied to sophisticated methodological and technological approaches enabling investigation at various levels, from behavioral responses to the neural activity that underlie them. This approach offers a valuable method by which to assess how decision-making operates across the lifespan, and this research can have immediate impact in terms of better understanding real-life decisions faced by elderly populations in a variety of important domains.

描述（由申请人提供）：该项目提出了一系列实验，将有助于新兴的衰老神经经济学领域，该领域试图通过检查行为和潜在的神经基质来了解整个生命周期中决策的组成过程。拟议的研究力求开始具体说明决策机制，特别是构成决策过程的审议和情感组成部分。多年来，情感对决策的影响在很大程度上被忽视了，但最近对我们的情感状态如何影响我们所做的决定类型的兴趣提供了一个令人兴奋的机会，以扩大我们对这一最重要过程的了解。此外，研究情感和审议过程在多大程度上对整个生命周期的决策产生不同的影响，可以为评估这些基本的认知功能提供重要的线索。具体来说，拟议中的实验将使用功能性磁共振成像（fMRI）来测量参与经济决策的人的大脑功能。这一建议建立在作者以前的工作基础上，研究了人类在与另一个人的社会互动中做出决策的过程。这些研究发现了可靠的、独立的神经活动模式，这些模式与情感偏见和审慎偏见相对应，并表明随后的决定似乎是基于这些不同的动机。在本提案中，将系统地检验先前研究中提出的假设。使用功能磁共振成像和最后通牒和信任游戏的变体的实验将更深入地探索情感和审议过程在多大程度上影响年轻人和老年人的决策。神经经济学领域正在迅速发展，来自许多不同领域的研究人员试图了解人类决策行为的神经基础。它允许在有意义的社会互动中研究个体，这些互动与复杂的方法和技术方法相结合，从而能够在各个层面进行调查，从行为反应到作为其基础的神经活动。这种方法提供了一种有价值的方法来评估决策如何在整个生命周期中运作，这项研究可以在更好地理解老年人在各种重要领域所面临的现实生活中的决定方面产生直接的影响。
