Awareness of errors has been considered a clinical feature of acquired apraxia of speech (AOS). However, there is limited research examining error awareness in speakers with AOS. The purpose of this investigation was to examine awareness of errors and explore the relationship between awareness of errors and treatment outcomes in speakers with AOS.
Twenty speakers with AOS and aphasia produced mono- and multisyllabic words in a repetition task. Following each production, speakers were asked to judge the accuracy of their production (i.e., correct or incorrect). Then, speakers received Sound Production Treatment.
Judgment accuracy of productions for the group ranged from 20% to 96%. There was a weak relationship between judgment accuracy and probe performance at posttreatment (r = .47) and a moderate relationship between judgment accuracy and probe performance at follow-up (r = .53).
Findings indicate that speakers with AOS varied in their ability to judge the accuracy of their productions. For some speakers, the ability to judge the accuracy of their productions did not coincide with their production accuracy of treatment stimuli at posttreatment and at follow-up. Further research is needed to explore the relationship between error awareness and treatment outcomes.
对错误的觉察被认为是获得性言语失用症（AOS）的一种临床特征。然而，针对患有AOS的说话者的错误觉察情况进行研究的却很有限。本调查的目的是检验对错误的觉察，并探究患有AOS的说话者的错误觉察与治疗结果之间的关系。
20名患有AOS和失语症的说话者在一项重复任务中产出单音节和多音节单词。每次产出后，要求说话者判断自己产出的准确性（即正确或错误）。然后，说话者接受语音产出治疗。
该组产出的判断准确率在20%至96%之间。治疗后，判断准确率与探测表现之间存在弱相关性（r = 0.47），随访时判断准确率与探测表现之间存在中度相关性（r = 0.53）。
研究结果表明，患有AOS的说话者在判断自己产出准确性的能力上存在差异。对于一些说话者来说，判断自己产出准确性的能力与治疗后及随访时治疗刺激的产出准确性并不一致。需要进一步研究来探究错误觉察与治疗结果之间的关系。
