神经活动多元模式中语义信息的存在已被探索作为测量知识和学习的方法。使用功能磁共振成像，我们调查了美国手语 (ASL) 的新手学习者是否对以众所周知的语言（英语）或新学的语言（ASL）呈现的单词表现出语义类别的重叠表示。我们发现新手参与者的手语和言语之间部分共享神经模式的证据。这一结果为跨模态语言处理中即使是短暂的学习对神经表征的影响提供了证据。
The presence of semantic information in multivariate patterns of neural activity has been explored as a method of measuring knowledge and learning. Using fMRI, we investigated whether novice learners of American Sign Language (ASL) showed overlapping representations of semantic categories for words presented in a well-known (English) or newly learned (ASL) language. We find evidence of neural patterns that were partially shared between sign and speech in novice participants. This result provides evidence for the influence of even brief learning on neural representations in cross-modality language processing.
