There is strong empirical evidence that English-speaking children with spoken language difficulties (SLD) often have phonological awareness (PA) deficits. The aim of this study was to explore longitudinally if this is also true of pre-school children speaking German, a language that makes extensive use of derivational morphemes which may impact on the acquisition of different PA levels.
Thirty 4-year-old children with SLD were assessed on 11 PA subtests at three points over a 12-month period and compared with 97 four-year-old typically developing (TD) children.
The TD-group had a mean percentage correct of over 50% for the majority of tasks (including phoneme tasks) and their PA skills developed significantly over time. In contrast, the SLD-group improved their PA performance over time on syllable and rhyme, but not on phoneme level tasks. Group comparisons revealed that children with SLD had weaker PA skills, particularly on phoneme level tasks.
The study contributes a longitudinal perspective on PA development before school entry. In line with their English-speaking peers, German-speaking children with SLD showed poorer PA skills than TD peers, indicating that the relationship between SLD and PA is similar across these two related but different languages.
有确凿的实证证据表明,有口语困难(SLD)的英语儿童往往存在语音意识(PA)缺陷。本研究的目的是纵向探究对于说德语的学龄前儿童而言情况是否也是如此,德语大量使用派生词素,这可能会影响不同语音意识水平的习得。
在12个月的时间里,对30名患有口语困难的4岁儿童在11项语音意识子测试上进行了三次评估,并与97名发育正常(TD)的4岁儿童进行比较。
发育正常组在大多数任务(包括音素任务)中的平均正确百分比超过50%,且他们的语音意识技能随时间显著发展。相比之下,口语困难组在音节和韵律方面的语音意识表现随时间有所提高,但在音素水平任务上没有提高。组间比较显示,患有口语困难的儿童语音意识技能较弱,尤其是在音素水平任务上。
该研究为入学前语音意识发展提供了纵向视角。与说英语的同龄人一样,说德语的患有口语困难的儿童语音意识技能比发育正常的同龄人差,这表明在这两种相关但不同的语言中,口语困难与语音意识之间的关系是相似的。
