像英国手语（BSL）这样的手语包括部分词汇化的结构，描述对象处理或操作处理结构。对象大小呈梯度变化，但不清楚处理手形是分类地还是梯度地描述处理过的对象。本研究探讨手语经验对手型知觉的影响。聋人手语者和听力正常的非手语者完成感知手型识别和辨别任务。我们研究了聋人手语手语者与听力正常的非手语手语者相比，对手部形状的感知是连续的还是连续的，以及反应时间是否受到语言表征的调节。结果表明，聋人和听力感知者对动态呈现的手型的二元分类在类别边界上具有较高的判别准确率，而在类别内的判别准确率较低，但高于偶然性，表明知觉分类不是由语言经验唯一介导的。然而，RTs显示两组在处理时间上存在重大差异；聋人手语的即时反应反应了更强的类别偏见和对边界的敏感度，表明潜在的语言表征。此外，类别内的手型差异影响聋人手语的歧视RTs，其方式表明了分级类别组织，手型原型为类别奠定了基础。这些发现提供了对处理手势的内部组织的洞察，并突出了手语，认知和手势之间的复杂关系。
Sign languages like British Sign Language (BSL) include partially lexicalized constructions depicting object handling or manipulation – handling constructions. Object sizes gradiently vary, yet it is unclear whether handling handshapes depict handled objects categorically or gradiently. This study investigates the influence of sign language experience on perception of handling handshapes. Deaf signers and hearing non-signers completed perceptual handshape identification and discrimination tasks. We examined whether deaf BSL signers perceived handshape continua categorically or continuously compared with hearing non-signers, and whether reaction times were modulated by linguistic representations. The results revealed similar binary categorization of dynamically presented handling handshapes as deaf and hearing perceivers displayed higher discrimination accuracy on category boundaries, and lower, but above chance, within-category discrimination, suggesting that perceptual categorization was not uniquely mediated by linguistic experience. However, RTs revealed critical differences between groups in processing times; deaf signers’ RTs reflected stronger category bias and increased sensitivity to boundaries, suggesting underlying linguistic representations. Further, handshape variability within categories influenced deaf signers’ discrimination RTs in a manner that suggested graded category organization, with handshape prototype grounding the category. These findings provide an insight into the internal organization of handling handshapes and highlight the complex relationship between sign language, cognition, and gesture.
