Populations are rapidly ageing and research which helps to foster healthy ageing is urgently required. 'Cognition' is the processes involved in thinking and acquiring knowledge (e.g., attention, memory). Short-term ('working') memory holds small amounts of information in mind, moment-to-moment, which can be used to carry out important cognitive tasks in everyday life. Visual working memory allows us to maintain a limited amount of visual information temporarily, but this ability declines with age. Importantly, declines in visual working memory could hinder everyday functions such as identifying a face or safely driving a car. However, using efficient strategies could potentially help to boost the amount of information we can store in visual working memory. One potential strategy is using visual semantics, that is, familiarity and meaning, to help process novel information. For example, if you notice a person resembles someone familiar, you would be better able to identify them later. Using effective strategies during working memory tasks could benefit independence and quality of life in older age, and help to slow or prevent cognitive impairment.This project will develop understanding of the relationships amongst ageing, strategy use, cognitive performance, and brain functioning. Study 1 will comprise an experimental investigation of the behavioural and neural (EEG) effects of young and older adults' strategies on visual working memory capacity. Based on this new knowledge, in Study 2, we will co-design a novel strategy training protocol with community-based older adults. In Study 3, via a pilot randomised controlled trial, we will investigate the potential effectiveness of the intervention for boosting older adults' visual working memory capacity.

人口正在迅速老龄化，迫切需要有助于促进健康老龄化的研究。 “认知”是涉及思考和获取知识（例如注意力、记忆）的过程。短期（“工作”）记忆每时每刻在脑海中保存少量信息，可用于执行日常生活中的重要认知任务。视觉工作记忆使我们能够暂时保留有限数量的视觉信息，但这种能力会随着年龄的增长而下降。重要的是，视觉工作记忆的下降可能会阻碍日常功能，例如识别面孔或安​​全驾驶汽车。然而，使用有效的策略可能有助于增加我们在视觉工作记忆中存储的信息量。一种潜在的策略是使用视觉语义，即熟悉度和意义，来帮助处理新信息。例如，如果您注意到一个人与熟悉的人相似，您稍后就能更好地识别他们。在工作记忆任务中使用有效的策略可以有益于老年人的独立性和生活质量，并有助于减缓或预防认知障碍。该项目将加深对衰老、策略使用、认知表现和大脑功能之间关系的理解。研究 1 将包括对年轻人和老年人的视觉工作记忆能力策略的行为和神经 (EEG) 影响进行实验研究。基于这些新知识，在研究 2 中，我们将与社区老年人共同设计一种新颖的策略培训方案。在研究 3 中，通过一项试点随机对照试验，我们将调查干预措施对于提高老年人视觉工作记忆能力的潜在有效性。
