This investigation compares the performances of 24 African American children, diagnosed as language impaired (LI) and receiving school-based language therapy, to 2 groups of typically developing peers (N = 48) on 5 traditional types of language assessment measures. Three of the measures were derived from child-centered free play language sample analyses and included average length of communication units (MLCU), frequencies of complex syntax, and numbers of different words. Two of the measures examined language comprehension and included responses to requests for information in the form of Wh-questions and responses to probes of active and passive sentence constructions. The performances of the group of children with language impairments were significantly lower on each measure than that of chronological age matched African American children who were typically developing. Sensitivity and specificity of the battery appeared excellent. The findings are discussed in terms of the potential of these informal language measures to contribute to a culturally fair assessment protocol for young African American children.
本研究将24名被诊断为语言障碍(LI)并接受学校语言治疗的非裔美国儿童的表现,与两组发育正常的同龄人(N = 48)在5种传统语言评估指标上进行了比较。其中三项指标源自以儿童为中心的自由玩耍语言样本分析,包括交流单元平均长度(MLCU)、复杂句法频率和不同单词数量。另外两项指标考察语言理解,包括对以Wh-疑问句形式提出的信息请求的回答,以及对主动和被动句子结构探测的回答。在每项指标上,语言障碍儿童组的表现均显著低于年龄匹配的发育正常的非裔美国儿童。该测试组合的敏感性和特异性似乎都很好。研究结果从这些非正式语言测试对制定针对非裔美国幼儿的文化公平评估方案的潜力方面进行了讨论。
