概括
对于有语言障碍的儿童来说,在语法干预后,MLU和TTR等传统措施可能无法有效地追踪语法干预后的进展. 衡量目标的特定技能,例如第三人称单数-s,更有益.
科学领域:
- 语音和语言病理学 语言病理学
- 儿童语言获取 儿童语言获取
- 语言发展语言发展.
背景情况:
- 语言样本分析 (LSA) 是监测语言障碍儿童的常见工具.
- 发音的平均长度 (MLU) 和类型标记比率 (TTR) 是经常用于语法目标的LSA措施.
- 这些传统措施可能无法充分捕捉针对性语法干预的进展.
研究的目的:
- 为了比较四个LSA措施在干预后对特定语法形态的进度监测的有效性.
- 评估MLU和TTR是否足以衡量DLD儿童有针对性的语法治疗的结果.
- 强调在儿科语言干预中谨慎地测量治疗技能的重要性.
主要方法:
- 来自6名患有发育性语言障碍 (DLD) 的学前儿童的自发语言样本的定性分析.
- 儿童接受了第三人称单数 -s (3s) 形态的治疗.
- 分析了四个指标:MLU,TTR,%准确度为3s,紧张和协议生产力 (TAP) 得分为3s.
主要成果:
- 直接评估治疗目标的措施 (3s准确度和TAP得分) 显示了最一致的增加.
- 在MLU的变化并不总是与目标语法技能的改进保持一致.
- 在所有参与者中,TTR显示出最小的变化.
结论:
- MLU和TTR可能不足以作为对DLD学龄前儿童3s治疗的唯一结果措施.
- 精确测量所涉及的技能,并使用多种结果措施是有益的.
- 需要对LSA进行进一步的研究,以测量儿科语言障碍的结果.

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...

Language, whether spoken, signed, or written, consists of specific components: lexicon and grammar. The lexicon is the vocabulary of a language, comprising its words. Grammar is the set of rules used to convey meaning through the lexicon. For example, English grammar adds “-ed” to most verbs to indicate past tense. Words are formed by combining phonemes, which are the basic sound units of a language. Different languages have different sets of phonemes (e.g., “ah” vs.
