项目摘要
DESCRIPTION (provided by applicant): Children with specific language impairment (SLI), a spoken language impairment in the absence of any obvious causal factors, make up about 7% of the population and have substantially poorer long-term academic and social outcomes as compared to their peers. During the preschool years, deficits in acquisition and use of grammatical morphology and syntax are among the most commonly observed impairments. Current interventions for morphology and syntax have limited efficacy (Law et al., 2004). Enhanced language intervention techniques would improve the long-term positive outcomes for this population. This research grant draws on input-driven approaches to typical language learning, which propose that highly frequent examples help scaffold acquisition of grammatical constructions by providing a stable exemplar to facilitate linking the meaning of grammatical construction to the form. Similarly, theories of word learning and learning of artificial grammars suggest that using atypical exemplars may promote learning to a greater degree as compared to highly typical exemplars. The research program extends these theories to intervention by using computational modeling and behavioral methods for the purpose of examining the role of stimulus selection and presentation on intervention outcomes. Two early- efficacy studies will be carried out. One is focused on teaching children with SLI to use past tense using two different means of selecting verbs for use in intervention. The second is focused on teaching a novel morpheme to children with SLI and children with typical language using three different input distributions. The results of the behavioral studies will be linked to computational models enabling us to test input structures and means of selecting stimuli that go beyond what is feasible to examine behaviorally. This will make it possible to test hypotheses about what will improve interventions more efficiently than with traditional behavioral methods alone. The investigator has substantial experience working with children with SLI and assessing the use of grammatical morphology in children. However she lacks expertise in the areas of computational modeling, design of intervention studies, and communicating results to speech pathologists. The training component of this grant will ensure that the investigator is capable of using computational modeling techniques in concert with behavioral results to better understand how children learn. It will also enhance the investigator's ability to independently carry out intervention studies and communicate research results to practitioners. The University of Iowa is well known for work in the areas of specific language impairment and computational modeling and has a long history of clinically relevant research. Extant collaborations between researchers in psychology and communications disorders make this an ideal environment for this training to take place. The training opportunities will help the investigator launch an independent research career that investigates ways to improve remedi-ation of language disorders.
描述(由申请人提供):患有特定语言障碍(SLI)的儿童,在没有任何明显因果因素的情况下出现口语障碍,约占人口的7%,与同龄人相比,其长期学术和社会成果明显较差。在学龄前,语法形态和句法的习得和使用方面的缺陷是最常见的障碍之一。目前对形态学和句法的干预具有有限的功效(Law等人,2004年)。加强语言干预技术将改善这一人群的长期积极成果。这项研究资助借鉴了输入驱动的方法来学习典型的语言,它提出了高频率的例子,通过提供一个稳定的范例,以促进语法结构的意义与形式的联系,帮助支架收购的语法结构。同样,单词学习和人工语法学习的理论表明,与高度典型的范例相比,使用非典型范例可以在更大程度上促进学习。该研究计划通过使用计算建模和行为方法将这些理论扩展到干预,以研究刺激选择和呈现对干预结果的作用。将进行两项早期疗效研究。一个是专注于教SLI儿童使用过去时态使用两种不同的手段选择动词用于干预。第二个实验是通过三种不同的输入方式,对SLI儿童和典型语言儿童进行一种新的语素教学。行为研究的结果将与计算模型相联系,使我们能够测试输入结构和选择刺激的手段,这些刺激超出了行为学上可行的范围。这将使人们有可能检验关于什么将比传统的行为方法更有效地改善干预措施的假设。研究者具有与SLI儿童合作并评估儿童语法形态学使用的丰富经验。然而,她缺乏在计算建模,干预研究的设计和沟通结果的语言病理学家领域的专业知识。该补助金的培训部分将确保研究人员能够使用计算建模技术与行为结果相结合,以更好地了解儿童如何学习。它还将提高研究人员独立开展干预研究并将研究结果传达给从业人员的能力。爱荷华州大学以在特定语言障碍和计算建模领域的工作而闻名,并且在临床相关研究方面有着悠久的历史。心理学和沟通障碍研究人员之间的现有合作使其成为进行这种培训的理想环境。培训机会将帮助研究人员开始独立的研究生涯,研究改善语言障碍补救的方法。
