While decisions and actions are commonly measured in assessments of sport performance, one's perception - including perception of the environment and perception of one's ability level - is less understand. The purpose of this study was to explore if soccer players have accurate perceptions of their ability and if they can recalibrate and retain these perceptions with experience. The sensorimotor soccer interceptive task involves three separate blocks, first viewing only, action, and second viewing only. The 50% chance threshold for success was determined for each block. Performance error was defined as the difference in 50% chance threshold between perceived and actual ability for both perceived blocks. Consistency of one's perceived ability was calculated for each block, with smaller values indicating greater precision in perceived ability. Decision-making errors were calculated during the action block and labeled as either a defensive error (cautious) or a miss error (aggressive). Construct validity of the sensorimotor soccer interceptive task was assessed by comparing expert and less expert female soccer players. Both groups exhibited a significant overestimation when introduced to a new sport-related task. However, athletes were able to recalibrate from initial overestimations more closely aligning perceived ability to actual ability level. Expert players demonstrate superior real-time decision-making when compared to less expert players.To determine the capacity of athletes to retain the initial recalibration a 1-week retention test was performed. Athletes were able to recalibrate from initial overestimations in their ability and retain this recalibration at a 1-week retention test. In addition to retaining the initial recalibration, athletes continuously improved the accuracy of their perceptions, becoming more precisely calibrated with each interaction with the task, which is indicative of learning.Healthy athletes demonstrate the ability to recalibrate and retain the perceptions of their ability in a sport-related task. This work will bolster new research into rehabilitation and return to sport assessments, improving our ability to safely and successfully return athletes to their sport following injury.
