In this study, we examined the verb morphology system of Turkish-speaking preschoolers with developmental language disorder (DLD) and compared their use to that of two groups of typically developing (TD) children. We report data from a total of 80 monolingual children - 40 children with DLD, 20 TD age-matched children and 20 TD younger MLU-matched children. Language samples obtained from the children served as the source of the data. The results show that the children with DLD were less accurate in their use of verb suffixes than both the younger and the age-matched TD children. The most frequent error types included use of bare stems, omission of the suffix, and replacing one finite verb suffix with another. The distinction between witnessed past and reported past also posed a challenge. Multi-level model results showed that phonemic length and irregular morphophonology were the best predictors of the children's level of accuracy. These results indicate that even though Turkish is considered a "verb friendly" language, children with DLD do not succeed in closing the gap with their TD peers. The complex interplay of morphology and phonology in Turkish appears to be the major obstacle for children with DLD acquiring this agglutinative language.
在本研究中，我们考察了患有发育性语言障碍（DLD）的讲土耳其语的学龄前儿童的动词形态系统，并将他们的使用情况与两组发育正常（TD）的儿童进行比较。我们报告了总共80名单语儿童的数据——40名患有DLD的儿童、20名年龄匹配的发育正常儿童和20名语法平均长度匹配的年龄较小的发育正常儿童。从儿童那里获得的语言样本作为数据来源。结果表明，患有DLD的儿童在动词后缀的使用上比年龄较小和年龄匹配的发育正常儿童的准确性更低。最常见的错误类型包括使用光秃秃的词干、省略后缀以及用一个限定动词后缀替换另一个。见证过去和报道过去之间的区别也构成了一项挑战。多层次模型结果表明，音素长度和不规则形态音位学是儿童准确性水平的最佳预测指标。这些结果表明，尽管土耳其语被认为是一种“对动词友好”的语言，但患有DLD的儿童仍未能成功缩小与发育正常同龄人之间的差距。土耳其语中形态学和音位学的复杂相互作用似乎是患有DLD的儿童习得这种黏着语的主要障碍。
