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.
许多失语症患者报告说，尽管口语命名有困难，但他们能够在脑海中说出单词。在这里，我们研究了失语症患者个体内部言语（IS）体验的差异，以检验以下假设：自我报告的 IS 反映了完整的语音检索，并且发音输出处理对于 IS 不是必需的。参与者（N=53）报告了他们在安静的图片命名任务中正确地在内部命名项目的能力。我们将这种自我报告的 IS 与口语图片命名以及一系列衡量命名所需的基本过程（即语音检索和输出处理）的任务进行了比较。对这些措施的三个独立分析的结果表明，自我报告的 IS 与语音检索有关，而语音输出过程不是 IS 的必要组成部分。我们认为，自我报告的 IS 可能是一种有临床价值的衡量标准，可以帮助临床决策，例如在命名障碍的诊断和治疗方面。
