The purpose of the present study was to examine the utility of a novel morpheme learning task for indexing typical language abilities in children characterized by diverse language backgrounds.
Three groups of 5- to 6-year-old children were tested: monolingual speakers of English, native speakers of Spanish who also spoke English (Spanish-L1 bilinguals), and native speakers of English who also spoke Spanish (English-L1 bilinguals). All children were taught a new derivational morpheme /ku/ marking part-whole distinction in conjunction with English nouns. Retention was measured via a receptive task, and sensitivity and reaction time (RT) data were collected.
All three groups of children learned the novel morpheme successfully and were able to generalize its use to untaught nouns. Furthermore, language characteristics (degree of exposure and levels of performance on standardized measures) did not contribute to bilingual children's learning outcomes.
Together, the findings indicate that this particular version of the novel morpheme learning task may be resistant to influences associated with language background and suggest potential usefulness of the task to clinical practice.
本研究的目的是检验一种新颖的词素学习任务对于评估具有不同语言背景儿童的典型语言能力的效用。
对三组5至6岁的儿童进行了测试:以英语为母语的单语者、也说英语的西班牙语母语者(西班牙语-第一语言双语者)以及也说西班牙语的英语母语者(英语-第一语言双语者)。所有儿童都学习了一个新的派生语素/ku/,它与英语名词一起表示整体与部分的区别。通过接受性任务测量记忆保持情况,并收集敏感性和反应时间(RT)数据。
所有三组儿童都成功学会了这个新的词素,并能够将其用法推广到未学过的名词上。此外,语言特征(接触程度和标准化测试中的表现水平)对双语儿童的学习成果没有影响。
这些发现共同表明,这种特定版本的新颖词素学习任务可能不受与语言背景相关的影响,并表明该任务在临床实践中具有潜在的实用性。
