美国手语手形反映交际效率压力
American Sign Language Handshapes Reflect Pressures for Communicative Efficiency
AI总结：
本文通过量化美国手语手形的发音与感知努力，发现高频手形更易产生，证明交际效率压力主要源于美国手语自身使用而非英语借词。
摘要：
交际效率是语言学和认知心理学中的一个关键议题，许多研究已证明以最小努力进行交际的压力如何引导自然语言的形式。然而，这一现象在手语中很少被探讨。本文展示了美国手语（ASL）中的手形如何反映这些效率压力，并为视觉-手势模态中的交际效率提供了新证据。我们聚焦于美国手语本土手语词和从英语借入的手语词中的手部构型，以比较来自美国手语和英语使用的效率压力。首先，我们开发了新的方法来量化产生手形所需的发音努力和识别手形所需的感知努力。然后，我们分析了交际努力与美国手语或英语使用统计之间的相关性。我们的发现表明，频繁出现的美国手语手形更容易产生，并且交际效率压力主要来自美国手语使用，而非英语词汇借用。
英文摘要：
Communicative efficiency is a key topic in linguistics and cognitive psychology, with many studies demonstrating how the pressure to communicate with minimal effort guides the form of natural language. However, this phenomenon is rarely explored in signed languages. This paper shows how handshapes in American Sign Language (ASL) reflect these efficiency pressures and provides new evidence of communicative efficiency in the visual-gestural modality. We focus on hand configurations in native ASL signs and signs borrowed from English to compare efficiency pressures from both ASL and English usage. First, we develop new methodologies to quantify the articulatory effort needed to produce handshapes and the perceptual effort required to recognize them. Then, we analyze correlations between communicative effort and usage statistics in ASL or English. Our findings reveal that frequent ASL handshapes are easier to produce and that pressures for communicative efficiency mostly come from ASL usage, rather than from English lexical borrowing.
