Effects of Hearing Loss on Maintaining and Switching Attention
Acta Acustica united with Acustica, 2018 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 ...
