The aim of this research was to evaluate the ability to switch attention and selectively attend to relevant information in children (10-15 years) with persistent listening difficulties in noisy environments. A wide battery of clinical tests indicated that children with complaints of listening difficulties had otherwise normal hearing sensitivity and auditory processing skills. Here we show that these children are markedly slower to switch their attention compared to their age-matched peers. The results suggest poor attention switching, lack of response inhibition and/or poor listening effort consistent with a predominantly top-down (central) information processing deficit. A deficit in the ability to switch attention across talkers would provide the basis for this otherwise hidden listening disability, especially in noisy environments involving multiple talkers such as classrooms.
本研究旨在评估在嘈杂环境中持续性听力困难的儿童(10-15 岁)切换注意力和选择性关注相关信息的能力。大量临床测试表明,抱怨听力困难的儿童的听力敏感性和听觉处理能力正常。在这里,我们发现这些孩子在注意力切换方面明显比同龄儿童慢。结果表明,注意力切换能力差、缺乏反应抑制和/或听力努力不足,这与主要的自上而下(中枢)信息处理缺陷一致。在说话者之间切换注意力的能力缺陷为这种隐藏的听力障碍提供了基础,尤其是在涉及多个说话者的嘈杂环境中,如教室。
