人们发现，许多有特定语言障碍的英语儿童在使用语法形态方面特别薄弱。在另一篇文献中，许多符合相同主题描述的儿童在涉及快速声音变化感知的任务中表现出明显的局限性。在这项研究中，我们试图确定有特定语言障碍的儿童的语法形态限制与其在几个感知对比中的表现概况之间是否存在相似之处。由于大多数英语语法语素相对于语音流中的相邻语素的持续时间较短，因此我们假设具有特定语言障碍的儿童在区分对比部分的持续时间比非对比部分的持续时间更短的语音刺激方面特别弱。由八名患有特定语言障碍且记录有形态学困难的儿童组成的小组的结果证实了这些预测。提供了观察到的形态-感知相似性的几种可能的解释。
Many English-speaking children with specific language impairment have been found to be especially weak in their use of grammatical morphology. In a separate literature, many children meeting the same subject description have shown significant limitations on tasks involving the perception of rapid acoustic changes. In this study, we attempted to determine whether there were parallels between the grammatical morphological limitations of children with specific language impairment and their performance profiles across several perceptual contrasts. Because most English grammatical morphemes have shorter durations relative to adjacent morphemes in the speech stream, we hypothesized that children with specific language impairment would be especially weak in discriminating speech stimuli whose contrastive portions had shorter durations than the noncontrastive portions. Results from a group of eight children with specific language impairment with documented morphological difficulties confirmed these predictions. Several possible accounts of the observed morphology-perception parallels are offered.
