Document Summary
Lexicon structure and lexical access in sign. Lemma (semantic and morphosyntactic info) vs lexeme (phonological form) I. e. , they aren"t stored as frozen chunks. Speech: evidence for the bipartite organization of the lexicon (can access the grammatical info, like gender, but not the form of the word) Sign: different phonological parameters are retrieved independently. Handshape + location + orientation = onset are often retrieved first. Role of iconicity in lexical retrieval in sign: none. 83% in speech vs 34% in sign before recognition. Bases of signs where movement is a morpheme are recognized earlier than signs where movement is phonological. No qualitative differences, nor quantitative differences for most slip types, but: Phrasal blends are much more common in german than. Internal is more important in sign than external. Similar neural activation patterns in speech vs sign, modulo the obvious production/perception channel-related differences. Activation in auditory association cortex in deaf signers.
