Modeling of grammatical forms has been used in conjunction with conversational recast treatment in various forms. This study tests the relative effect of providing bombardment prior to or after recast treatment.
Twenty-eight children with developmental language disorder participated in daily conversational recast treatment for morpheme errors. This treatment was either preceded or followed by a brief period of intensive auditory bombardment. Generalization to untreated lexical contexts was measured throughout the treatment period to assess the degree of learning and how quickly the onset of measurable learning occurred.
There were no significant differences in elicited use of morphemes for the groups of children who received auditory bombardment before or after enhanced conversational recast treatment. However, there was a difference in the number of children who could be considered treatment responders versus nonresponders, favoring those who received auditory bombardment after recast treatment.
A brief period of auditory bombardment is a relatively low cost addition to recast treatment methods, given how little time it takes. There is a small but measurable advantage to following recast treatment with a period of auditory bombardment.
语法形式建模已以各种形式与对话重铸疗法结合使用。本研究测试了在重铸疗法之前或之后进行强化训练的相对效果。
28名发育性语言障碍儿童参与了针对语素错误的日常对话重铸疗法。在这种疗法之前或之后有一段短暂的强化听觉训练。在整个治疗期间测量对未处理词汇语境的泛化情况以评估学习程度以及可测量学习开始的速度。
在强化对话重铸疗法之前或之后接受听觉训练的儿童组在语素的引出使用方面没有显著差异。然而，在可被视为治疗反应者与无反应者的儿童数量上存在差异，更有利于那些在重铸疗法之后接受听觉训练的儿童。
鉴于所需时间很少，一段短暂的听觉训练是重铸治疗方法中成本相对较低的补充。在重铸疗法之后进行一段时间的听觉训练有一个小但可测量的优势。
