概括

与年轻人相比,老年人对语音节奏时间的敏感性较低,这影响了他们预测即将发生的语音事件的能力. 这种与年龄相关的时间期望变化影响了语音理解.

科学领域:

听觉神经科学听觉神经科学
精神声学是一种精神声学.
语音感知语音感知

背景情况:

老年人经常表现出较差的听觉时间处理,这与理解语言的困难有关.
语音节奏在创造有助于语音理解的时间期望方面发挥着至关重要的作用.

研究的目的:

调查与年龄相关的对语音节奏敏感性的差异.
检查语音节奏上下文如何影响口语句子时间变化的检测.

主要方法:

在年轻和年长的正常听力听众中,采用了时间转移检测范式.
听众检测到与完整或改变前面的节奏呈现的句子中变化的间隙时间.

主要成果:

两个年龄组都受益于完整的节奏,显示较低的检测值.
年轻的听众对缩短的间隔比延长的间隔更敏感;年长的听众缺乏这种方向敏感性.
具有更好的节奏歧视的老年听众对早期时刻偏差的敏感性更高.

结论:

年轻和年长的听众都利用语音节奏来形成时间期望.
随着年龄的变化,言语时间预期的变化,特别是早期的偏差,可能会导致老年人的言语理解困难.

Perception of Sound Waves

Perception of Sound Waves

The human ear is not equally sensitive to all frequencies in the audible range. It may perceive sound waves with the same pressure but different frequencies as having different loudness. Moreover, the perception of sound waves depends on the health of an individual's ears, which decays with age. The health of one's ears may also be affected by regular exposure to loud noises.
The pitch of a sound depends on the frequency and the pressure amplitude of the source. Two sounds of the same...
