Research has shown that young children with speech sound disorders may have weaknesses in phonological processing. However, such skills have not been thoroughly examined in adolescents with residual speech sound errors. Therefore, this study compared the phonological processing abilities of adolescents with residual speech sound errors to those of normally speaking peers.
Two nonword repetition tasks, multisyllabic word repetition, spoonerisms, phoneme reversals, and an elision task were used to compare the phonological processing skills of 10-14-year-olds with residual speech sound errors that include rhotic phonemes (RE, n = 13) to those of normally speaking (NS, n = 14) adolescents of similar age and receptive vocabulary abilities.
The 2 groups were found to differ on 5 of the 6 phonological processing tasks. Discriminant analysis showed that 85% of the participants could be correctly classified into the RE and NS groups based solely on phonological processing skills.
The possible nature of the phonological processing impairment is discussed in the context of current theoretical understanding. It is recommended that when planning assessment and intervention for adolescents with residual speech sound errors, clinicians be cognizant of the fact that the adolescents may also have weaknesses in phonological processing.
研究表明，患有语音障碍的幼儿可能在语音处理方面存在缺陷。然而，对于仍有语音错误的青少年，此类技能尚未得到充分研究。因此，本研究比较了仍有语音错误的青少年与正常同龄人在语音处理能力方面的差异。
使用两项非词重复任务、多音节词重复、首音互换、音素颠倒和一项省略任务，比较了10至14岁仍有包括r音素在内的语音错误的青少年（RE组，n = 13）与年龄和接受性词汇能力相似的正常青少年（NS组，n = 14）的语音处理技能。
发现两组在6项语音处理任务中的5项上存在差异。判别分析表明，仅根据语音处理技能，85%的参与者能够被正确地分为RE组和NS组。
在当前理论理解的背景下，讨论了语音处理障碍可能的性质。建议在为仍有语音错误的青少年规划评估和干预时，临床医生应认识到这些青少年在语音处理方面可能也存在缺陷。
