Working memory (WM) for sign language has an architecture similar to that for speech-based languages at both functional and neural levels. However, there are some processing differences between language modalities that are not yet fully explained, although a number of hypotheses have been mooted. This article reviews some of the literature on differences in sensory, perceptual and cognitive processing systems induced by auditory deprivation and sign language use and discusses how these differences may contribute to differences in WM architecture for signed and speech-based languages. In conclusion, it is suggested that left-hemisphere reorganization of the motion-processing system as a result of native sign-language use may interfere with the development of the order processing system in WM.
手语工作记忆(WM)在功能和神经水平上与基于言语的语言相似。然而,语言模态之间存在一些尚未完全解释的处理差异,尽管已经提出了一些假设。本文回顾了一些关于听觉剥夺和手语使用引起的感觉、知觉和认知处理系统差异的文献,并讨论了这些差异如何导致手语和基于言语的语言 WM 结构的差异。总之,有人认为,由于母语是手语,运动处理系统的左半球重组可能会干扰 WM 中顺序处理系统的发展。
