In many tasks people have to coordinate the information from several sources. An example would be driving a car while listening to directions. The driver has to establish a correspondence between a visual picture and verbal instructions. This paper addresses two questions concerning information coordination. Is there an ability to coordinate information received from several sources that is different from the ability to deal with information from each source, alone? Does coordination simply involve allocating resources to deal with the component tasks, or does the act of coordination itself constitute a separate task? Four experiments examined the coordination of a verbal component task with a visual-spatial and with an auditory component task. The results showed that the ability to coordinate perceptual and verbal information is separate from the ability to deal with either perceptual or verbal information, alone. A simple resource sharing model was not adequate in explaining how coordination occurred. We relate our results to a model in which perceptual reasoning occurs independently of verbal processing, but transforming perceptual information into a propositional form is affected by concurrent verbal processing.
在许多任务中，人们必须协调来自多个来源的信息。一个例子是边开车边听指示。司机必须在视觉画面和口头指令之间建立对应关系。本文探讨了两个与信息协调有关的问题。是否存在一种协调从多个来源接收的信息的能力，它不同于单独处理来自每个来源的信息的能力？协调仅仅涉及分配资源来处理各个子任务，还是协调行为本身构成一项单独的任务？四项实验研究了言语子任务与视觉空间子任务以及听觉子任务之间的协调。结果表明，协调感知和言语信息的能力与单独处理感知或言语信息的能力是分开的。一个简单的资源共享模型不足以解释协调是如何发生的。我们将我们的结果与一个模型联系起来，在这个模型中，感知推理独立于言语处理发生，但将感知信息转化为命题形式会受到同时进行的言语处理的影响。
