Previous work has shown that talking on a mobile phone leads to an impairment of visual attention. Gunnell et al. (2020) investigated the locus of these dual-task impairments and found that although phone conversations led to cognitive delays in response times, other mechanisms underlying particular selective attention tasks were unaffected. Here, we investigated which attentional networks, if any, were impaired by having a phone conversation. We used the attentional network task (ANT) to evaluate performance of the alerting, orienting, and executive attentional networks, both in conditions where people were engaged in a conversation and where they were silent. Two experiments showed that there was a robust delay in response across all three networks. However, at the individual network level, holding a conversation did not influence the size of the alerting or orienting effects but it did reduce the size of the conflict effect within the executive network. The findings suggest that holding a conversation can reduce the overall speed of responding and, via its influence on the executive network, can reduce the amount of information that can be processed from the environment.

电话交谈会影响行政人员，但不会影响警报或定向网络。

先前的研究表明，使用手机通话会导致视觉注意力受损。冈内尔等人。（2020 年）研究了这些双重任务障碍的轨迹，发现尽管电话交谈导致响应时间的认知延迟，但特定选择性注意任务背后的其他机制并未受到影响。在这里，我们调查了哪些注意力网络（如果有的话）因电话交谈而受损。我们使用注意网络任务 (ANT) 来评估警报、定向和执行注意网络的性能，无论是在人们进行对话还是在他们保持沉默的情况下。两项实验表明，所有三个网络的响应都存在明显的延迟。然而，在个人网络层面，进行对话不会影响警报或定向效果的大小，但确实减少了执行网络中冲突效果的大小。研究结果表明，进行对话可以降低整体响应速度，并且通过其对执行网络的影响，可以减少可以从环境中处理的信息量。（PsycInfo 数据库记录 (c) 2022 APA，保留所有权利）。
