Here, we report on a case study in which a\u00a0person with transradial amputation identified prosthetic hand postures using artificial somatosensory feedback. He successfully combined five artificial somatosensory percepts to achieve above-chance performance of 95.0% and 75.7% in identifying four and seven postures, respectively. We studied how artificial somatosensation and the extant hand representation are combined in the decision-making process by providing two mappings between the prosthetic sensor and the location of the sensory percept: (1) congruent, and (2) incongruent. The participant\u2019s ability to combine and engage with the sensory feedback significantly differed between the two conditions. The participant was only able to successfully generalize prior knowledge to novel postures in the congruent mapping. Further, he learned postures more accurately and quickly in the congruent mapping. Finally, he developed an understanding of the relationships between postures in the congruent mapping instead of simply memorizing each individual posture. These experimental results are corroborated by a Bayesian decision-making model which tracked the participant\u2019s learning.<\/jats:p>","DOI":"10.1038\/s41598-020-62970-4","type":"journal-article","created":{"date-parts":[[2020,4,20]],"date-time":"2020-04-20T10:03:07Z","timestamp":1587376987000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":24,"title":["Combination of Simultaneous Artificial Sensory Percepts to Identify Prosthetic Hand Postures: A Case Study"],"prefix":"10.1038","volume":"10","author":[{"given":"Jacob L.","family":"Segil","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1541-4703","authenticated-orcid":false,"given":"Ivana","family":"Cuberovic","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Emily L.","family":"Graczyk","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Richard F. ff.","family":"Weir","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2298-8510","authenticated-orcid":false,"given":"Dustin","family":"Tyler","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2020,4,20]]},"reference":[{"key":"62970_CR1","doi-asserted-by":"publisher","first-page":"60","DOI":"10.1016\/j.jhevol.2014.08.006","volume":"78","author":"AJM Key","year":"2015","unstructured":"Key, A.
