In our everyday lives we must often perform two tasks at once, or attend to more than one stimulus at a time. For example, we may talk on our cellular phone while driving, or take notes while listening to a lecture. Many of the tasks we try to perform in combination require attention. At odds with our desire to do everything at once is the fact that there are finite limits on how much information we can attend to and process at any one time. Such attentional limitations are frustrating in that they often predict the imminent failure of one or more tasks under conditions of multi-tasking even when two tasks do not share the same input (e.g., eyes) or output (e.g., hands) systems. However, our failures in multi-task situations can provide valuable information concerning functional and fundamental human processing limitations on attention.

在我们的日常生活中，我们经常必须同时完成两项任务，或者同时关注不止一种刺激。例如，我们可以边开车边打手机，或者边听课边记笔记。我们试图共同完成的许多任务都需要注意。与我们想要一次完成所有事情的愿望不同的是，我们一次可以处理和处理的信息量是有限的。这种注意力限制是令人沮丧的，因为即使当两个任务不共享相同的输入(例如，眼睛)或输出(例如，手)系统时，它们也经常在多任务的条件下预测一个或多个任务即将失败。然而，我们在多任务情况下的失败可以提供有关注意的功能性和基本人类处理限制的有价值的信息。
