其他研究发现，当信息可以根据刺激和反应特征进行区分时，更容易分散注意力。本研究扩展了这些结果，并探讨了双任务的性能是否是一个功能的相似性的中央处理，更具体地说，语义相似性的竞争消息。在双耳分听任务中，受试者在并发消息中检测到目标，这些消息要么语义不同，需要不同的中央处理（混合条件），要么语义相似，需要类似的中央处理（相同条件）。三个标准来确定是否在混合条件下的任务调用不同的资源。结果进行了讨论的三个隐喻的资源：燃料，结构和技能。
Other studies have found that it is easier to divide attention when messages can be discriminated on the basis of stimulus and response features. The present study extended these results and explored whether dual-task performance is a function of similarity of central processing and, more specifically, the semantic similarity of the competing messages. In a dichotic listening task, subjects detected targets in concurrent messages that either differed semantically and required different central processing (the mixed condition) or were semantically similar and required similar central processing (the same condition). Three criteria are developed to determine whether the tasks in the mixed condition call upon distinct resources. The results are discussed in terms of three metaphors for resources: fuel, structure, and skills.
