概括
在噪音中的句子识别随着年龄的增长而下降,特别是在调制噪声条件下. 到第四个十年,性能差异就会出现,突出显示与年龄相关的听觉处理变化.
科学领域:
- 听力学 听力学是指听力学.
- 老年学是一门学科.
- 语音感知 语音感知
背景情况:
- 听觉处理,包括在噪音中识别句子,可能会受到老化的影响.
- 了解不同噪音环境中与年龄相关的变化对于听力健康至关重要.
研究的目的:
- 研究年龄对正常听力成年人在各种噪音条件下对句子识别的影响.
- 为了确定年龄是否会根据背景噪声的类型对句子识别产生不同的影响.
主要方法:
- 113名21-65岁的成年人被按年龄分组,并对句子识别进行了测试.
- 刺激包括语音形式的噪音 (SSN),振幅调制的SSN (AM-SSN) 和说话者 (2MB,4MB,4FB) 在-5dB的SNR.
- 在五个不同的噪音条件下评估了性能.
主要成果:
- 在所有测试的噪音条件下,句子识别得分随着年龄的增长而下降.
- 年龄产生了差异性的影响,在AM-SSN和2MB中,与其他噪音相比,早些时候 (第四个十年) 发现了显著的下降.

Cognitive Development During Adulthood
957
Cognitive development continues throughout adulthood, undergoing significant shifts across early, middle, and late stages. Individual transition occurs from adolescent idealism to pragmatic and adaptable thinking in early adulthood. During this period, individuals learn to integrate personal beliefs with the recognition that other perspectives are equally valid. Exposure to the complexities of modern society, diverse experiences, and higher education contribute to this adaptive thought process,...

Language Development
977
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...

Pharmacodynamics in Geriatric Patients: Effects of Age

Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...
