In three experiments, cost-benefit analysis was used to determine the role of attention in the processing of auditory information. In two experiments consonant-vowel syllables were presented monaurally, while in the third the mode of presentation was dichotic. For all three experiments the ability to detect a target stimulus under conditions in which precued location information was valid or invalid was contrasted with detection in a neutral condition where no location information was provided. The results indicated that attention can be effectively deployed under monaural conditions when either a simple detection or a discriminative response is required. Similar conclusions cannot be reached when considering the effectiveness of attention under conditions of dichotic listening. These results are discussed in relation to accounts which argue that dichotic listening performance is critically dependent upon auditory disembedding and where attention is viewed as a late process involving response selection.
在三项实验中，采用成本效益分析来确定注意力在听觉信息处理中的作用。在两项实验中，辅音-元音音节单耳呈现，而在第三项实验中，呈现方式为双耳分听。对于所有三项实验，将在预提示位置信息有效或无效的条件下检测目标刺激的能力与在未提供位置信息的中性条件下的检测能力进行了对比。结果表明，当需要简单检测或辨别反应时，注意力可以在单耳条件下有效部署。在考虑双耳分听条件下注意力的有效性时，无法得出类似的结论。结合一些观点对这些结果进行了讨论，这些观点认为双耳分听表现严重依赖于听觉分离，并且注意力被视为涉及反应选择的后期过程。
