许多失语症患者报告说，尽管有说出名字的困难，但他们能够在脑海中说出单词。在此，我们研究了失语症参与者内在言语体验的个体差异，以验证自我报告的内在言语反映完整的语音检索和发音输出加工对内在言语不是必要的假设。参与者（N = 53）报告了他们在无声的图片命名任务中正确命名物品的能力。我们将这种自我报告的IS测量与口头图片命名和一系列测量命名所需的潜在过程（即语音检索和输出处理）的任务进行了比较。对这些测量的三个独立分析结果表明，自我报告的IS与语音检索有关，语音输出过程不是IS的必要组成部分。我们认为自我报告的IS可能是一种临床有价值的测量方法，可以帮助临床决策有关失范的诊断和治疗。
Many individuals with aphasia report the ability to say words in their heads despite spoken naming difficulty. Here, we examined individual differences in the experience of inner speech (IS) in participants with aphasia to test the hypotheses that self-reported IS reflects intact phonological retrieval and that articulatory output processing is not essential to IS. Participants (N = 53) reported their ability to name items correctly internally during a silent picture-naming task. We compared this measure of self-reported IS to spoken picture naming and a battery of tasks measuring the underlying processes required for naming (i.e., phonological retrieval and output processing). Results from three separate analyses of these measures indicate that self reported IS relates to phonological retrieval and that speech output processes are not a necessary component of IS. We suggest that self-reported IS may be a clinically valuable measure that could assist in clinical decision-making regarding anomia diagnosis and treatment.
