Iconic gesture-speech integration is a relatively recent field of investigation with numerous researchers studying its various aspects. The results obtained are just as diverse. The definition of iconic gestures is often overlooked in the interpretations of results. Furthermore, while most behavioral studies have demonstrated an advantage of bimodal presentation, brain activity studies show a diversity of results regarding the brain regions involved in the processing of this integration. Clinical studies also yield mixed results, some suggesting parallel processing channels, others a unique and integrated channel. This review aims to draw attention to the methodological variations in research on iconic gesture-speech integration and how they impact conclusions regarding the underlying phenomena. It will also attempt to draw together the findings from other relevant research and suggest potential areas for further investigation in order to better understand processes at play during speech integration process.
标志性手势-言语整合是一个相对较新的研究领域，众多研究人员对其各个方面进行了研究。所获得的结果同样多种多样。在结果解释中，标志性手势的定义常常被忽视。此外，虽然大多数行为研究表明双模态呈现具有优势，但关于参与这种整合处理的脑区，脑活动研究显示出多样的结果。临床研究也产生了混合结果，一些研究表明存在并行处理通道，另一些则表明是独特的整合通道。本综述旨在提请注意标志性手势-言语整合研究中的方法差异，以及它们如何影响关于潜在现象的结论。它还将尝试汇总其他相关研究的结果，并提出进一步调查的潜在领域，以便更好地理解言语整合过程中起作用的过程。
