DESCRIPTION (provided by applicant): The ability to perform prospective memory tasks (remembering to perform an action in the future) is essential for maintaining an independent lifestyle. For instance, a person who can not remember to take medication or to turn off the stove will require daily assistance. Understanding how the processes underlying prospective memory performance might differ in younger and older adults is essential for preventing decline and for creating useful means of assistance to those individuals who are having difficulty with this everyday memory task. The proposed research uses mathematical modeling techniques test hypotheses, derived from a new theory of prospective memory, about how age differences in attention and memory interact to produce age differences in prospective memory performance. A mathematical model will be validated and used determine the cognitive processes underlying age differences in prospective memory. Four experiments will evaluate age differences in prospective memory accuracy and age differences in the impact of prospective memory tasks on on-going activities. In addition, the role of resource limitations in older adults? performance on prospective and retrospective tasks will be assessed using a measure of working memory capacity.

描述（由申请人提供）：执行前瞻性记忆的能力 任务（记住将来执行动作）对于 保持独立的生活方式。例如，一个不能 记住服用药物或关闭炉子将需要每天需要 协助。了解前景记忆的基础过程 年轻人和老年人的表现可能有所不同 防止下降并为那些人创造有用的援助手段 在这项日常记忆任务上遇到困难的个人。这 拟议的研究使用数学建模技术测试假设， 源自一种新的潜在记忆理论，涉及年龄差异 注意力和记忆相互作用以在预期记忆中产生年龄差异 表现。数学模型将得到验证并使用 预期记忆年龄差异的基本认知过程。四个 实验将评估预期记忆准确性的年龄差异和 预期记忆任务对正在进行的影响的年龄差异 活动。另外，资源限制在老年人中的作用？ 将使用 衡量工作记忆能力。
