Children with speech sound disorders (SSDs) often struggle with forming early representations for phonemes and words, which could impact their speech production as well as their lexical access. This difficulty may limit their ability to accurately identify nonexemplar productions of words, such as developmental misarticulations produced by peers. The purpose of this study was to examine word interpretation of misarticulated words by children with SSD.
Seventeen monolingual English-speaking preschoolers were assessed for language, phonological processing, and articulation skills. Participants heard three types of words: accurate productions (e.g., "leaf"), common misarticulated productions (e.g., "weaf"), uncommon misarticulated productions (e.g., "yeaf"), and unrelated nonwords (e.g., "gim"). Children were presented with these words aurally and asked to select the picture that matched what they heard-either a real object or a blank square.
The proportion of real object picture selections was calculated for each word type and compared within subjects. The findings indicate that children with SSD reliably associated common misarticulated words with pictured objects more frequently than they did in the uncommon misarticulation condition. These results were compared between subjects to typically developing (TD) peers' responses using a one-way analysis of variance. The results indicate that children with SSD identified common substitutions as real object pictures more often than TD peers.
The results of this study suggest that children with SSD are sensitive to the commonness of misarticulations; however, they accept common substitutions as real object pictures significantly more often than TD peers.
语音障碍(SSD)儿童在形成音素和单词的早期表征方面常常存在困难,这可能会影响他们的言语产生以及词汇提取。这种困难可能会限制他们准确识别单词非典型发音的能力,比如同龄人出现的发育性发音错误。本研究的目的是考察患有SSD的儿童对发音错误单词的词义理解。
对17名以英语为母语的单语学龄前儿童进行语言、语音处理和发音技能评估。参与者听三种类型的单词:正确发音(如“leaf”)、常见发音错误(如“weaf”)、不常见发音错误(如“yeaf”)以及无关的非单词(如“gim”)。以听觉方式向儿童呈现这些单词,并要求他们选择与所听到内容匹配的图片——要么是真实物体,要么是空白方块。
计算每种单词类型选择真实物体图片的比例,并在受试者内部进行比较。研究结果表明,与不常见发音错误的情况相比,患有SSD的儿童更频繁地将常见发音错误的单词与所描绘的物体可靠地联系起来。使用单因素方差分析将这些结果在受试者之间与典型发育(TD)同龄人进行比较。结果表明,患有SSD的儿童比TD同龄人更频繁地将常见的替代发音识别为真实物体图片。
本研究结果表明,患有SSD的儿童对发音错误的常见性敏感;然而,他们比TD同龄人更频繁地将常见的替代发音接受为真实物体图片。
