Production and perception of location in signed language

描述(申请人提供)：本研究的目的是在发音音系学的理论框架内，以发音手势的详细语音测量为基础，调查手语中位置的语音参数，类似于用于语音研究的发音手势。本研究首次从动作限制的角度对正常成年手语者的手语产生进行了研究，并考察了手语知觉与手语产生之间的交互作用。第一个实验将考察美国手语(ASL)在正常和快速条件下对一组一致的语音位置的移动，以便测量这些位置的范围和变异性。第二个实验将检查英国手语(BSL)中的类似数据，从而进行跨语言比较。最后的实验将使用前两个研究的结果作为知觉刺激的基础，比较ASL和BSL对位置的知觉和产生。希望本研究能更好地理解手语中的跨语言变异和共性，以及对手语语音形式的运动和知觉制约，从而为手语结构的两种理论模式提供借鉴。

DESCRIPTION (provided by applicant): The aim of the proposed research is to investigate the phonological parameter of location in signed language, within the theoretical framework of articulatory phonology, on the basis of detailed phonetic measures of articulatory gestures, similar to those in use for speech research. This study is the first to focus on production in normal adult signers in terms of motor constraints, and to examine the interaction between sign language perception and production. The first experiment will examine movements to a set of consistent phonological locations in American Sign Language (ASL) under normal and fast conditions so that the range and variability of those locations can be measured. The second experiment will examine analogous data in British Sign Language (BSL), thereby allowing for cross-linguistic comparison. The final experiment will compare perception and production of location in both ASL and BSL, using the results of the first two studies as the basis for the perceptual stimuli. It is hoped that this research will lead to a better understanding of cross-language variation and universals, as well as motoric and perceptual constraints on phonological form in signed language, thereby informing both theoretical models of sign language structure.
