Humans acclimate to the CC illusion through repeated exposure; however, substantial inter-individual differences in acclimation exist, which remain poorly understood. To address this, we investigated several potential predictors of individual acclimation to the CC illusion. METHODS: Eleven subjects were exposed to the CC illusion for up to 50 25-minute acclimation sessions. The metric of acclimation rate was calculated as the slope of each subject\u2019s linear increase in spin rate across sessions. As potential predictors of acclimation rate, we gathered age, gender, demographics, and activity history, and measured subjects\u2019 vestibular perceptual thresholds in the yaw, pitch, and roll rotation axes. RESULTS: We found a significant, negative correlation (p\u200a=\u200a0.025) between subjects\u2019 acclimation rate and roll threshold, suggesting lower thresholds yielded faster acclimation. Additionally, a leave-one-out cross-validation analysis indicated that roll thresholds are predictive of acclimation rates. Correlations between acclimation and other measures were not found but were difficult to assess within our sample. CONCLUSIONS: The ability to predict individual differences in CC illusion acclimation rate using roll thresholds is critical to optimizing acclimation training, improving the feasibility of fast-rotation, short-radius centrifugation for artificial gravity.<\/jats:p>","DOI":"10.3233\/ves-210019","type":"journal-article","created":{"date-parts":[[2021,11,19]],"date-time":"2021-11-19T11:25:41Z","timestamp":1637321141000},"page":"305-316","source":"Crossref","is-referenced-by-count":4,"title":["Predicting individual acclimation to the cross-coupled illusion for artificial gravity"],"prefix":"10.1177","volume":"32","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7899-578X","authenticated-orcid":false,"given":"Kathrine N.","family":"Bretl","sequence":"first","affiliation":[{"name":"University of Colorado Boulder, 3775 Discovery Drive, Boulder, CO, United States"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Torin K.","family":"Clark","sequence":"additional","affiliation":[{"name":"University of Colorado Boulder, 3775 Discovery Drive, Boulder, CO, United States"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","reference":[{"key":"10.3233\/VES-210019_ref2","doi-asserted-by":"crossref","first-page":"1309","DOI":"10.1097\/MAO.0b013e31822e5bee","article-title":"The modified romberg balance test: normative data in U.S. adults","volume":"32","author":"Agrawal","year":"2011","journal-title":"Otology & Neurotology"},{"key":"10.3233\/VES-210019_ref3","first-page":"205","article-title":"Thresholds for the perception of whole body angular movement about a vertical axis","volume":"60","author":"Benson","year":"1989","journal-title":"Aviation, Space, and Environmental Medicine"},{"key":"10.3233\/VES-210019_ref4","first-page":"1088","article-title":"Thresholds for the detection of the direction of whole-body, linear movement in the horizontal plane","volume":"57","author":"Benson","year":"1986","journal-title":"Aviation, Space, and Environmental Medicine"},{"key":"10.3233\/VES-210019_ref5","doi-asserted-by":"crossref","unstructured":"Berm\u00fadez Rey M.C. , T.K.
