Orofacial Somatosensory Effects for the Word Segmentation Judgement

Abstract : Word segmentation is one of the initial processes for lexical perception. While visual inputs can help it in acoustically ambiguous situations, the effect of orofacial somatosensory inputs to this process is unknown. We here tested how orofacial somatosensory inputs affect word segmentation for lexical perception. We carried out identification tests using a French phrase consisting of a definitive and a noun, segmented differently according to the place of the accents in the phrase. In the test applying somatosensory stimulation at various timings along the phrase with neutral accent, we found that the lexical perception was significantly and systematically biased depending on the somatosensory stimulus timing. This bias effect was not seen when two somatosensory stimuli were applied to emphasize one accent position rather than the other by changing force amplitude between two positions. The results show and quantify the role the orofacial somatosensory system plays in lexical perception.
