Most older adults show declines in cognitive functions such as attention and memory. In contrast, emotional and motivational capacities tend to stabilize, or even improve, with age. Little is known about whether older adults affective strengths can be tapped to reduce the impact of age-related cognitive deficits. The proposed research addresses this issue by investigating the effect of reward motivation on cognition and the brain across the lifespan. Exploring the potential for reward-based cognitive amelioration in older adults is an endeavour of critical societal relevance, given that adults aged 65 and up form the fastest-growing segment of Canadian society today.

大多数老年人在注意力和记忆等认知功能中表现出下降。相反，随着年龄的增长，情感和动机能力倾向于稳定甚至改善。关于老年人是否可以利用情感强度来减少与年龄相关的认知缺陷的影响，知之甚少。拟议的研究通过调查奖励动机对认知和整个生命周期的大脑的影响来解决这个问题。鉴于65岁及65岁及以上的成年人构成了当今加拿大社会增长最快的部分，探索老年人基于奖励的认知缓解潜力是批判性社会相关性的努力。
