概括
这项研究发现,口吃的孩子在对话任务中,在口吃的句子中产生了更复杂的语法. 任务要求对句子类型的口吃频率或语言生产力没有显著的影响.
科学领域:
- 语音和语言病理学 语言病理学
- 儿童心理学 儿童心理学
- 语言学的语言学.
背景情况:
- 了解口儿童 (CWS) 的任务需求和语言生产之间的关系对于有效的评估至关重要.
- 之前的研究已经探索了CWS的语言变异,但特定任务要求对语法复杂性和流利性的影响仍然是需要进一步研究的领域.
研究的目的:
- 为了比较不同任务要求对语言生产力和语法复杂性的影响,在口吃和非口吃的句子中比较语法复杂性.
- 在不同语言任务中分析学校年龄的CWS中口吃和典型的不流利性.
- 研究特定任务对CWS语言特征的影响.
主要方法:
- 语言样本分析 (LSA) 对14名学龄儿童 (9-15岁) 进行了三项任务:对话,寓言重述和批判性思维.
- 计算机语言分析程序分析了语言生产力 (单词,句子) 和语法复杂性 (元认知动词,动词短语,单词中发音的平均长度 - MLUw).
- 使用%的口吃音节 (%SS) 和%的典型失语 (%TD) 来量化失语,并进行统计分析,包括重复测量ANOVA和非参数测试.
主要成果:
- 在不同任务中,口吃和不口吃的句子之间,语言生产力没有显著差异,这表明命题性和可变性的影响有限.
- 在口吃的句子中观察到较高的语法复杂性,相比于在单词,短语和发音层面的非口吃句子,特别是在对话任务中.
- %的音节 (%SS) 在任务需求之间没有显著差异.
结论:
- 任务需求影响CWS中的语法复杂性,对话任务在口吃的句子中引起更高的复杂性.
- 调查结果表明,评估计划应考虑任务需求,以准确评估CWS中的语言能力和口吃模式.
- 这项研究提供了对口吃儿童语言需求,语法结构和不流利之间的相互作用的见解.

Language and Cognition

Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.

Language Development

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...
