This paper investigates whether the semantic and phonological levels in speech production are specific to spoken languages or universal across modalities. We examined semantic and phonological effects during Catalan Signed Language (LSC: Llengua de Signes Catalana) production using an adaptation of the picture-word interference task: native and non-native signers were asked to sign picture names while ignoring signs produced in the background. The results showed semantic interference effects for semantically related distractor signs and phonological facilitation effects when target signs and distractor signs shared either Handshape or Movement but phonological interference effects when target and distractor shared Location. The results suggest that the general distinction between semantic and phonological levels seems to hold across modalities. However, differences in sign language and spoken production become evident in the mechanisms underlying phonological encoding, shown by the different role that Location, Handshape, and Movement play during phonological encoding in sign language.
本文研究言语产生中的语义和语音层面是特定于口语语言还是跨模态通用的。我们使用图片 - 单词干扰任务的一种变体，研究了加泰罗尼亚手语（LSC：Llengua de Signes Catalana）产生过程中的语义和语音效应：要求本土和非本土手语使用者在忽略背景中出现的手势的同时，打出图片名称。结果显示，对于语义相关的干扰手势存在语义干扰效应，当目标手势和干扰手势在手形或动作上相同时存在语音促进效应，而当目标和干扰手势在位置上相同时存在语音干扰效应。结果表明，语义和语音层面的总体区分似乎跨模态成立。然而，手语和口语产生的差异在语音编码的潜在机制中变得明显，这体现在位置、手形和动作在手语语音编码过程中所起的不同作用上。
