法语系儿童的发育性阅读障碍 (DD) 与典型发育 (TD) 相比,不表现出独特的失语模式. 在这两个群体中,高流利率是常见的,需要特定语言的解释.
科学领域:
- 语言学的语言学.
- 发展心理学 发展心理学
- 语音语言病理学 语音语言病理学
背景情况:
- 不流利是一种复杂的语言现象,影响典型和非典型人口的语言生产.
- 有限的研究存在于发展语言系统的失流模式,特别是在患有神经发育障碍的儿童,如发育性阅读障碍 (DD).
- 以前的研究表明,在典型发育 (TD) 中,不流利率的语言特异性变化.
研究的目的:
- 分析8-12岁的法语儿童的不流利类型及其演变.
- 为了比较DD和TD儿童之间的流失模式.
- 调查失语与阅读困难之间的相关性.
主要方法:
- 总共有25名DD儿童和21名TD儿童,年龄在8-12.6岁之间,制作了自传叙事.
- 编码了七种类型的失语:部分单词的重复,单音单词的重复,其他重复,填充的暂停,替换,添加和废弃的发言.
- 每种失语类型的比例在各组之间进行了比较;斯皮尔曼相关性评估了与阅读表现和年龄的关系.
主要成果:
- 无论是DD还是TD的孩子都主要表现出充满的暂停,单音重复和替代.
- 两组都显示出高的整体失语率,超过10%.
- 不流利率与年龄无关,但与阅读表现的相关性仅在TD组中显著.
结论:
- 发育性阅读障碍 (DD) 在8-12岁的法语儿童中没有明显的失语模式.
- 在DD和TD儿童中,流利率相似,两组儿童的流利率都很高 (>10%),这在法语中是显着的.
- 解释DD中的不流利性需要谨慎,因为TD中也存在高率;病理值应根据语言进行调整,以避免过度估计缺陷.
