Feedback representing a performer's success for a given response has long been considered a critical factor in motor learning. Numerous studies of learning from augmented feedback have produced ambiguous guidelines for frequency design-some have recommended minimal feedback, whereas others have advocated more extensive feedback. Due to conflicting opinions regarding the frequency of Knowledge of Results, this study aimed to identify how young and old adults retain motor skills when two different frequency schedules of augmented feedback, everytrial and bandwidth are provided in acquisition. The participants performed a ballistic lever movement pattern involving four different target locations in a 1-day retention test. Behavioral outcomes and kinematic movement patterns were analyzed from two groups, young adults (20-30 years) and old adults (above 71 years) from a previously completed experiment. Results revealed that in both the age groups, bandwidth feedback promoted motor learning as compared to every-trial feedback. Further, bandwidth feedback promoted slower movements with longer durations as compared to an every-trial feedback schedule. Additionally, no significant interaction of age with any of the feedback conditions was found, suggesting that the effects of augmented feedback on motor learning are similar in young and old adults.
