The ability to intentionally control attention based on task goals and stimulus properties is critical to communication in many environments. However, when a person has a damaged auditory system, such as with hearing loss, perceptual organization may also be impaired, making it more difficult to direct attention to different auditory objects in the environment. Here we examined the behavioral cost associated with maintaining and switching attention in people with hearing loss compared to the normal hearing population, and found a cost associated with attending to a target stream in a multi-talker environment that cannot solely be attributed to audibility issues.
基于任务目标和刺激特性有意控制注意力的能力在许多环境中对于交流至关重要。然而，当一个人的听觉系统受损时，比如患有听力损失，知觉组织也可能会受到损害，使得将注意力指向环境中的不同听觉对象变得更加困难。在这里，我们研究了与听力损失人群相比，正常听力人群在维持和转换注意力方面的行为代价，并发现了在多说话者环境中关注目标流时存在一种代价，这种代价不能仅仅归因于可听度问题。
