A hypothesis to explain this failure might be that\nit is difficult to obtain true perceptual integration of a tactile signal with\ninformation from auditory speech: exploitation of tactile cues from a tactile\naid might require cognitive effort and so prevent speech understanding at the\nhigh rates typical of everyday speech. To test this hypothesis, we attempted to\ncreate true perceptual integration of tactile with auditory information in what\nmight be considered the simplest situation encountered by a hearing-impaired\nlistener. We created an auditory continuum between the syllables BA and VA, and\ntrained participants to associate BA to one tactile stimulus VA to another\ntactile stimulus. After training, we tested if auditory discrimination along\nthe continuum between the two syllables could be biased by incongruent tactile\nstimulation. We found that such a bias occurred only when the tactile stimulus\nwas above its previously measured tactile discrimination threshold. Such a\npattern is compatible with the idea that the effect is due to a cognitive or\ndecisional strategy, rather than to truly perceptual integration. We therefore\nran a further study, where we created a tactile version of the McGurk effect.\nWe extensively trained two Subjects over six days to associate four recorded\nauditory syllables with four corresponding apparent motion tactile patterns. In\na subsequent test, we presented stimulation that was either congruent or\nincongruent with the learnt association, and asked Subjects to report the\nsyllable they perceived. We found no analog to the McGurk effect. These\nfindings strengthen our hypothesis according to which tactile aids failed\nbecause integration of tactile cues with auditory speech occurred at a\ncognitive or decisional level, rather than truly at a perceptual level","url_abs":"http://arxiv.org/abs/1712.04987v1","url_pdf":"http://arxiv.org/pdf/1712.04987v1.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"why-early-tactile-speech-aids-may-have-failed","repo_url":"https://github.com/montoneguglielmo/stimuliFeelSpeechFrontier","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":0,"framework":"none","reach":null}],"tasks":[],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"syntology_url":null,"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
