Visual boundaries in sign motion: processing with and without lip-reading cues

Sign languages demonstrate a higher degree of iconicity than spoken languages. Studies on number unrelated sign show that the event structure verb signs is reflected in phonological form (Wilbur (2008), Malaia & Wilbur (2012), Krebs et al. (2021)). Previous research showed hearing non-signers (with no prior exposure to language) can use inherent visual dynamics correctly identify its (telic vs. atelic). In two EEG experiments, were presented with telic and atelic unfamiliar them, which they had classify two-choice lexical decision task their native language. The first experiment assessed timeline neural processing mechanisms telic/atelic without access lip-reading cues language, understand pathways for incorporation physical perceptual motion features into linguistic processing. second further probed impact information provided by (speech decoding based from face speaker, most importantly, lips) non-signers.
