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:

  • 发育句子评分 (DSS) 是一种用来分析儿童语言发展的工具.
  • 在不同年龄组和诊断类别中验证DSS的有效性对于其临床应用至关重要.
  • 之前的研究已经使用了DSS,但其适应不同样本长度的适应性需要进一步研究.

研究的目的:

  • 为了验证发育句子评分 (DSS) 工具在美国英语说话的成年人与儿童互动中区分年龄和诊断类别的能力.
  • 为了确定DSS子尺度是否因年龄和诊断类别而异.
  • 探索将DSS分析适应较短的语言样本的潜力.

主要方法:

  • 利用来自501名儿童 (年龄在2-6岁) 的数据,采用50个发言样本标准,以及来自TalkBank.org.org的842名儿童,采用25个发言样本标准.
  • 使用计算机语言分析实用程序来分析DSS总和子级分数.
  • 对比了典型发育的儿童和那些有迟说话史的儿童的语法概况.

主要成果:

  • DSS总分数对较年轻的孩子最有信息;随着时间的推移,分数在典型发育和迟说话的孩子之间趋同.
  • 主动词 (MV) 分级表现出最高的灵敏度.
  • 较短的语言样本 (25个发言) 与较长的 (50个发言) 一样具有信息意义.
  • 这项研究中的DSS得分通常高于Lee (1974) 之前报告的得分.

结论:

  • 较短的语言样本 (25个发言) 足以用于诊断和治疗规划.
  • 对于识别治疗目标而言,DSS,特别是MV子级,可能比诊断语言延迟更有价值.
  • 依靠李 (1974) 的原始DSS百分点得分可能会导致与典型发育的同龄人相比,具有显著语言滞后的儿童的低识别.
