在双模态注意任务中，人们对同时出现的冗余目标的反应比对单个目标的反应快。先前的研究支持“共激活”模型，其中冗余的目标都激活反应。本研究试图确定冗余目标是否独立激活反应，每个目标产生自己的激活，或交互式，与激活冗余目标产生的联合功能，他们的身份。实验1使用不同音高的听觉目标和不同位置的视觉目标。对冗余目标的反应在两者都高或低时比当它们不一致时更快。实验2改变了冗余配对的联合概率，对常见配对的反应比对稀有配对的反应快。结果表明，对冗余目标的反应是两种身份的联合函数，而不是独立激活的串联。（PsycINFO数据库记录（c）2016阿帕，保留所有权利）
In bimodal divided attention tasks, people respond faster to simultaneously presented redundant targets than to single targets. Previous research supports" coactivation" models, in which redundant targets both activate the response. This study sought to determine whether redundant targets activate the response independently, with each target producing its own activation, or interactively, with activation produced by redundant targets being a joint function of both their identities. Exp 1 used auditory targets varying in pitch and visual targets varying in location. Responses to redundant targets were faster when both were high or low than when they were incongruent. Exp 2 varied joint probability of redundant pairs, and responses were faster to common pairs than rare ones. The results indicate that responses to redundant targets are a joint function of both identities, not a concatenation of independent activations.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
