Gestures or signs?Comparing manual and non-manual constructions sharing the same form in co-speech gesture and sign language: a corpus-driven approach. (GeSi)

有许多手动和非手动结构不仅局限于手语，它们也可以在同语手势中观察到。在这个项目中，我们将系统地处理以下形式：手掌向上，扔掉，指向，列表浮标，眉毛扬起和侧身倾斜。虽然这些选择的结构中的一些已经被研究过，但其他形式仍在研究中，并且在手语和说话者之间没有对所有这些结构进行精细的分级比较。这个项目填补了这一空白。它的目的是提供一个详细的基于语料库的分析选择结构在共同语音手势和符号。我们的目标是确定手语中的这些结构在功能和结构上与手势中的类似形式有何不同，以及在多大程度上不同。由于这些结构具有相同的情态，它们将被给予相同的理论处理，并将沿着许多不同的维度进行研究，模糊了严格的手势-符号二元性，并支持对这些手动和非手动活动的理解，这些活动形成了一个跨情态连续体，沿着这个连续体进行功能约定俗成和词汇化。区分符号和手势这两个视觉交流的主要例子，该项目还提供了对不同渠道的互动和这种互动背后的语法系统的进一步见解，有助于建立一个新的无情态的语言和交流综合理论模型。

There is a number of manual and non-manual constructions which are not constrained to signed language only, they are also observed in co-speech gesture. The following forms will be systematically treated in this project: palm-up, throw away, pointing, list buoys, eyebrow raise and sidewards body leans. While some of these selected constructions have been researched, other forms remain un(der)studied and there is no fine-graded comparison of all these constructions between signers and speakers. This project fills this gap. It aims at providing a detailed corpus-based analysis of the selected constructions in both co-speech gesture and sign. The goal is to determine how – and to what degree – these constructions in sign language differ from comparable forms in gesture on both functional and formation grounds. As these constructions share the same modality, they will be given the same theoretical treatment and will be investigated along a number of various dimensions blurring the strict gesture-sign binary and backing the understanding of these manual and non-manual activities as forming a cross-modal continuum along which functional conventionalization and lexicalization takes place. Distinguishing signs and gesture, the two prime examples of visual communication, this project also provides further insights into the interaction of different channels and the grammatical system(s) underlying this interaction contributing to a new modality-free comprehensive theoretical model of language and communication.
