Emotional stimuli have been shown to influence language processing (both language comprehension and production) in people with aphasia (PWA); however, this finding is not universally reported. Effects of emotional stimuli on language performance in PWA could have clinical and theoretical implications, yet the sparsity of studies and variability among them make it difficult to appraise the significance of this effect. The purpose of this scoping review was to (a) determine the extent and range of research examining the effect of emotional stimuli on language processing in PWA, (b) summarize and evaluate research findings, and (c) identify gaps in the literature that may warrant future study.
PsycINFO, PubMed, Web of Science, and Cumulative Index to Nursing and Allied Health Literature databases were systematically searched for articles that compared performance in response to emotional and nonemotional stimuli on at least one language measure in one or more adults with aphasia. Data related to methods and results were extracted from each article and charted in Excel.
Five hundred forty unique articles were found, and 18 articles, consisting of 19 studies, met inclusion/exclusion criteria for this review. Of the 19 studies included, 11 studies reported enhanced performance on a language task for emotional compared to nonemotional stimuli, seven reported no difference, and one reported worse performance for emotional compared to nonemotional stimuli. Possible modulating variables such as task type, measurement, stimulus characteristics, and sample characteristics are discussed along with gaps in the literature.
The extent of research in this area is sparse; however, there does appear to be some early evidence for better performance in response to emotional over nonemotional stimuli in PWA for some, but not all, language processes investigated.
情绪刺激已被证明会影响失语症患者（PWA）的语言处理（包括语言理解和产生）；然而，这一发现并非普遍存在。情绪刺激对 PWA 语言表现的影响可能具有临床和理论意义，但由于研究数量稀少且彼此之间存在差异，因此难以评估这种影响的意义。本范围综述的目的是：(a)确定研究情绪刺激对 PWA 语言处理影响的范围和范围；(b)总结和评估研究结果；(c)确定文献中的空白点，这些空白点可能需要进一步研究。
系统地在 PsycINFO、PubMed、Web of Science 和 Cumulative Index to Nursing and Allied Health Literature 数据库中搜索了至少一项语言测量中比较情绪和非情绪刺激反应的文章，这些文章针对一个或多个失语症成年人。从每篇文章中提取与方法和结果相关的数据，并在 Excel 中进行图表绘制。
共发现 540 篇独特的文章，18 篇文章，包括 19 项研究，符合本综述的纳入/排除标准。在纳入的 19 项研究中，有 11 项研究报告称，与非情绪刺激相比，情绪刺激在语言任务上的表现更好，7 项研究报告称无差异，1 项研究报告称情绪刺激比非情绪刺激的表现更差。还讨论了可能的调节变量，如任务类型、测量、刺激特征和样本特征，以及文献中的空白点。
该领域的研究范围有限；然而，对于某些但不是所有研究的语言过程，似乎有一些早期证据表明 PWA 对情绪刺激的反应比对非情绪刺激的反应更好。
