Bandwidth knowledge of results on the learning of the saloon dart throwing task.

The effects of two different bandwidths of information of Knowledge of Results (KR) were investigated. 54 university students participated. The experiment consisted of an acquisition phase with practice of throwing a saloon dart as accurately as possible at a target lying on the floor 2.

Effect of bandwidth knowledge of results on the learning of a grip force control task.

An experiment was conducted to investigate the persistence of the effect of "bandwidth knowledge of results (KR)" manipulated during the learning phase of performing a manual force-control task. The experiment consisted of two phases, an acquisition phase with the goal of maintaining 60% maximum force in 30 trials, and a second phase with the objective of maintaining 40% of maximum force in 20 further trials. There were four bandwidths of KR: when performance error exceeded 5, 10, or 15% of the target, and a control group (0% bandwidth).
