本研究询问英国手语 (BSL) 的用户如何识别相连符号序列中的各个符号。我们研究了这是否是通过特定模态或通用模态分割程序来实现的。手语的一个特定模态特征是，在连续手语过程中，手语位置之间存在显着的过渡。我们使用符号识别任务来询问 BSL 签名者是否以及如何在分段中使用这些转换。总共 96 个真实的 BSL 信号之前是在目标位置或另一个位置（具有小或大过渡）产生的无意义信号。一半的过渡发生在同一主要身体区域（例如头部）内，一半发生在跨身体区域（例如胸部到手部）。聋人成年 BSL 用户（一组本地人和早期学习者，以及一组晚期学习者）在过渡最小时发现目标信号的效果最好，而在过渡较大时发现目标信号的效果最差。当存在位置变化时，两组在转移到不同身体区域时的表现都比在同一区域内时表现更好。这些发现表明，转换并没有以特定于模态的方式提供明确的符号边界线索。相反，我们认为较小的过渡通过将词汇搜索限制在位置邻域内的符号来帮助以模态一般方式进行识别，并且跨身体区域的过渡也通过为符号边界提供语音提示来帮助以模态一般方式进行分割。我们建议符号分割基于模态通用程序，这是核心语言处理机制。
This study asks how users of British Sign Language (BSL) recognize individual signs in connected sign sequences. We examined whether this is achieved through modality-specific or modality-general segmentation procedures. A modality-specific feature of signed languages is that, during continuous signing, there are salient transitions between sign locations. We used the sign-spotting task to ask if and how BSL signers use these transitions in segmentation. A total of 96 real BSL signs were preceded by nonsense signs which were produced in either the target location or another location (with a small or large transition). Half of the transitions were within the same major body area (e.g., head) and half were across body areas (e.g., chest to hand). Deaf adult BSL users (a group of natives and early learners, and a group of late learners) spotted target signs best when there was a minimal transition and worst when there was a large transition. When location changes were present, both groups performed better when transitions were to a different body area than when they were within the same area. These findings suggest that transitions do not provide explicit sign-boundary cues in a modality-specific fashion. Instead, we argue that smaller transitions help recognition in a modality-general way by limiting lexical search to signs within location neighbourhoods, and that transitions across body areas also aid segmentation in a modality-general way, by providing a phonotactic cue to a sign boundary. We propose that sign segmentation is based on modality-general procedures which are core language-processing mechanisms.
