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.

概括

人类语音运动学习显示出随着时间的推移强烈的保留能力. 两个并行记忆模式并存,基于听觉反进行切换,展示了不同的感觉运动记忆系统.

科学领域:

  • 神经科学是一个神经科学.
  • 认知科学 认知科学
  • 语音科学 语言科学

背景情况:

  • 人类的感觉运动学习主要是通过肢体运动在视觉空间环境中进行研究.
  • 语音听觉系统提供了一个独特的,功能独立的工作空间,用于研究感觉运动记忆.

研究的目的:

  • 调查语音声学感觉运动记忆的保留和特征.
  • 要确定语音运动记忆是否在功能上独立于视觉空间记忆.

主要方法:

  • 适应改变的听觉反被用来评估语音声学记忆.
  • 经过8小时和24小时的延迟,测试了记忆的持久性.
  • 在有和没有听觉反的条件下,检查了记忆检索.

主要成果:

  • 观察到语言运动学习的广泛保留 (约70%).
  • 语音声学记忆对获取方法 (突然与逐渐) 不敏感.
  • 两种并行语音生产模式 (适应和习惯) 并存,可以通过听觉反快速切换.

结论:

  • 人类的语音听觉系统作为一个独特的工作空间,用于表征感觉运动记忆.
