项目摘要

The purpose of this research is to better understand people's ability to manage more than one task at the same time, ands, in particular how that ability changes with advancing age. Specifically, the research will examine sources of difficulty in executing two overlapping tasks and in switching between tasks as the situation requires. In addition to behavioral studies, techniques for neuroimaging will be used to explore the areas of the brain that are activated by such high level cognitive demands, and how that activity is altered by structural or functional changes in the aging brain. The ability to manage multiple tasks is a regular and often vital part of everyday life and may well be impaired in old age. Examples range from simply preparing dinner (using a variety of potentially dangerous implements) to tending to a needy child or invalid while carrying out the tasks of daily living, to operating a vehicle (which may range from a passenger automobile to a jumbo jet).

这项研究的目的是更好地了解人们同时处理多项任务的能力，特别是这种能力如何随着年龄的增长而变化。具体来说，研究将探讨在执行两个重叠的任务，并在任务之间切换的情况下，需要困难的来源。除了行为研究，神经成像技术将用于探索大脑中被这种高水平认知需求激活的区域，以及这种活动如何被老化大脑的结构或功能变化所改变。管理多项任务的能力是日常生活中经常和经常重要的一部分，在老年时很可能会受到损害。例如，从简单地准备晚餐（使用各种可能有危险的工具）到在执行日常生活任务时照顾有需要的儿童或残疾人，再到操作车辆（从客运汽车到大型喷气式飞机）。
