These covert methods can supplement physical practice to augment learning outcomes, or even to serve as alternatives. However, knowledge gaps exist regarding the mechanisms of these covert processes and if\/how the encoding processes differ as compared to\r\nphysical practice. One way to better understand these processes is through the study of\r\nintermanual transfer. Across three experimental groups, participants either physically practised\r\n(PP), watched a partner practise (OBS), or imagined practising (MI) an underhand dart throw to a target on the floor. All groups were tested on the practised (dominant right) and non-practised (non-dominant left) hands in a pretest, immediate posttest, and 24hr retention test. All groups\r\nimproved from pre to posttest, particularly the PP group, and covert practice groups better\r\nretained these improvements across the retention interval. Although there were not the expected\r\nGroup X Hand interactions in the posttests, the correlations between amount of improvement in\r\nthe practised hand compared to the non-practised hand were strongest for the covert groups in\r\ncomparison to the PP group, showing a greater matching across the hands at the participant level\r\nfor these groups. Calculations of transfer, in terms of relative improvement in each hand from pre to posttests, did not yield group differences (being greater than 85% for all groups).\r\nSignificant offline gains were made by the OBS group as compared to the MI group, especially\r\nfor the non-practised hand. Measures of movement time (MT) and imagined movement time\r\n(iMT) gave an index of the equivalence between imagined and actual movements. The practised\r\nhand showed the best \u2018equivalence,\u2019 but there were no group differences. These data indicate a\r\ngeneral efficacy in covert motor practice methods for supporting transfer and the potential for\r\ncontinued learning over the retention interval. Transfer was comparably strong across all groups,\r\nparticularly even the PP group, surprisingly, suggesting similarities in sensorimotor representations acquired for this task.","language":"en"},{"key":"dc.language.iso","value":"eng","language":"en"},{"key":"dc.publisher","value":"University of British Columbia","language":"en"},{"key":"dc.rights","value":"Attribution-NonCommercial-NoDerivatives 4.0 International","language":"*"},{"key":"dc.rights.uri","value":"http:\/\/creativecommons.org\/licenses\/by-nc-nd\/4.0\/","language":"*"},{"key":"dc.title","value":"Investigating the relative impacts of covert versus overt motor practice modalities on the learning and intermanual transfer of a novel motor skill","language":"en"},{"key":"dc.type","value":"Text","language":"en"},{"key":"dc.degree.name","value":"Master of Science - MSc","language":"en"},{"key":"dc.degree.discipline","value":"Kinesiology","language":"en"},{"key":"dc.degree.grantor","value":"University of British Columbia","language":"en"},{"key":"dc.contributor.supervisor","value":"Hodges, Nicola J., 1970-","language":null},{"key":"dc.contributor.supervisor","value":"Kraeutner, Sarah N.","language":null},{"key":"dc.date.graduation","value":"2026-05","language":"en"},{"key":"dc.type.text","value":"Thesis\/Dissertation","language":"en"},{"key":"dc.description.affiliation","value":"Education, Faculty of","language":"en"},{"key":"dc.description.affiliation","value":"Kinesiology, School of","language":"en"},{"key":"dc.degree.campus","value":"UBCV","language":"en"},{"key":"dc.description.scholarlevel","value":"Graduate","language":"en"}]
