概括
听力损失 (DHH) 的儿童在杂的环境中处理句子的速度较慢. 快速说话也会减缓所有儿童的句子处理,但DHH儿童在现实世界听力条件下最容易受到影响.
科学领域:
- 审计处理 审计处理
- 在噪音中的语音感知.
- 儿童发展 儿童发展
背景情况:
- 课堂和游乐场环境对聋子或听障儿童 (DHH) 构成挑战.
- 对于语音速度和背景噪音如何影响DHH儿童实时句子处理的理解有限.
- 环境的倾听条件对于语言学习和学术成功至关重要.
研究的目的:
- 为了比较正常听力 (NH) 和DHH儿童之间的噪音中的实时句子处理.
- 研究语音速率 (快速与正常) 和背景噪音对句子处理的影响.
- 检查这些群体的认知因素 (工作记忆,词汇) 和句子处理之间的潜在关系.
主要方法:
- 27名NH和31名DHH儿童 (8-13岁) 参加了这次活动.
- 通过测量响应时间 (RT) 来评估句子处理,以检测16个说话者语噪声中的目标词.
- 语音以正常 (4.5音符/秒) 和快速 (6.1音符/秒) 的速度呈现.
主要成果:
- 无论是NH还是DHH的孩子,与正常语音相比,快速语音的RTs都较慢.
- DHH儿童在两种语音速率上均表现出比NH儿童慢的RT.
- 在DHH和NH儿童之间没有观察到言语速度的差异效应;然而,DHH儿童在噪音中通常较慢.
结论:
- 在杂的环境中快速说话可能会扰乱学龄儿童的句子处理.
- 在典型的噪音听力环境中,DHH儿童特别容易受到口语句子处理延迟的伤害.
- 这些发现强调了需要听力学支持和环境修改,以改善DHH儿童的听力条件.

Children master language quickly and with relative ease, supported by both biological predisposition and reinforcement. B. F. Skinner (1957) proposed that language is learned through reinforcement, while Noam Chomsky (1965) argued that language acquisition mechanisms are biologically determined.
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...

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.
