概括
耳植入物 (CI) 用户经常在杂的环境中扎. 一个简单的两个句子的测试揭示了许多CI用户的显著语音感知下降,突出了当前临床评估的局限性.
科学领域:
- 听力学 听力学是指听力学.
- 神经科学是一个神经科学.
- 语音和听力科学 语言和听力科学
背景情况:
- 许多耳植入物 (CI) 用户报告说,在现实环境中语音感知存在困难,尽管在标准临床测试中表现良好.
- 这种差异可能源于当前语音感知测试的有限生态有效性,这些测试通常使用单词或句子.
- 来自CI的听觉输入降级,加上有限的认知资源,可以挑战CI用户更苛刻的语音处理任务.
研究的目的:
- 研究序列式句子呈现对语音识别性能和语音识别用户和正常听力控制器的处理力度的影响.
- 为了确定通过瞳孔扩张测量的语音处理努力是否与两组任务难度相关.
主要方法:
- 参与者 (CI用户和正常听力控制) 在重复它们之前,先按顺序呈现一个或两个句子.
- 语音识别准确性被记录下来.
- 瞳孔膨胀被测量为认知处理努力的指数.
主要成果:
- 在处理两个句子时,CI用户表现出语音识别准确度的广泛下降,高达45个百分点,与标准临床测试成绩无关.
- 听力正常的听众对准确度的影响最小.
- 瞳孔测量数据密切跟踪了两个组的任务难度,即使在听力正常的个体中,他们的表现也接近天花板.
结论:
- 在许多CI用户中,语音识别因任务复杂度略有增加而显著降低,例如连续呈现两个句子.
- "两句问题"表明,即使是熟练的CI用户在单句测试中也可能在生态相关的听力环境中面临挑战.
- 临床的"两句话测试"可以为CI用户及其沟通伙伴的咨询和康复提供有价值的见解.

Barriers to Effective Communication I
8.8K
A communication barrier is any distortion or interruption during a conversation, resulting in miscommunication of the message. A good communicator should know these barriers and continuously check for the listener's understanding by obtaining feedback.
Communication barriers include the following:
Physiological barriers: They are limitations caused by a person's health condition or disability, such as hearing loss, poor eyesight, illness, or unconsciousness. An example to overcome this...

Higher Mental Functions of the Brain: Language
805
Language is a system of communication that allows the expression of thoughts, ideas, and feelings. The brain processes language in both hemispheres.
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...

Interference: Path Lengths
1.3K
Consider two sources of sound, that may or may not be in phase, emitting waves at a single frequency, and consider the frequencies to be the same.
Two special sources may be considered when they are in phase. This can be easily achieved by feeding the two sources from the same source. An example would be synchronizing the two speakers by feeding them with the same source, such as the sound waves produced by a tuning fork. This setup ensures that the two sources have the same frequency and are...

Chunking and Rehearsal in Sensory Memory
206
Improving short-term memory can be achieved through techniques like chunking and rehearsal. Chunking involves organizing information into larger, more manageable units. This technique is particularly useful for information that exceeds the typical memory span of between five and nine items. For instance, logging into an online account with a password like "ta89vq0179gz" involves grouping letters and numbers into three chunks—ta89, vq01, and 79gz. It makes large amounts of...

Hearing

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.
