概括
对所有听众来说,转移注意力比维持注意力更困难,特别是对于耳植入物 (CI) 的儿童来说,这些儿童在复杂的听觉环境中表现出增加的听力努力和注意力困难.
科学领域:
- 听觉感知研究 听觉感知研究
- 认知神经科学是一种认知神经科学.
- 在具有挑战性的声学条件下进行语音处理.
背景情况:
- 复杂的听力环境在日常生活中无处不在,需要显著的注意力控制才能有效地感知语音.
- 了解注意力动态如何影响不同人群的语音理解,包括具有典型听力 (TH) 和耳植入物 (CI) 的儿童,至关重要.
研究的目的:
- 研究注意力切换和维护对成年人,TH儿童和CI儿童的语音感知的影响.
- 探索这些群体在语音噪音任务中倾听力度,目光行为和认知能力之间的关系.
主要方法:
- 采用现实的视听模式 (AVATAR) 用于与成人和儿童 (TH和CI) 的语音噪音任务.
- 在需要注意力切换或维护的单语音和同时语音条件下评估语音接收值.
- 收集了眼睛跟踪数据 (瞳孔测量,凝视行为) 并进行了注意力,记忆和处理速度的认知测试.
主要成果:
- 所有小组都发现转移注意力比维持注意力更困难.
- 成年人在语音感知任务中表现优于儿童,TH儿童在语音感知任务中表现优于CI儿童.
- 患有智商障碍的儿童表现出更大的倾听力度和注意力困难,与他们的语音噪音挑战相关联.
结论:
- 保持注意力对所有参与者来说都不那么苛刻,而不是转移注意力,包括CI用户.
- 与正常听力同龄人相比,患有CI的儿童表现出更高的倾听力度和持续的注意力缺陷.
- 教育和环境方面的考虑对于有CI的儿童来说至关重要,以支持他们的听觉学习,即使有正常的听力值.

When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.

Auditory Perception

The auditory system is essential for sound perception, utilizing various critical structures. When sound waves enter the outer ear, they travel through the ear canal and cause the eardrum to vibrate. These vibrations are then transmitted to the middle ear, where three tiny bones – the malleus, incus, and stapes – amplify the sound. This amplification is crucial, as it ensures that the sound vibrations are strong enough to be conveyed to the inner ear. These vibrations then reach the...
