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 2.5 meters away until a specific area of the target was hit three trials in a row. Narrow bandwidth and Wide bandwidth groups received KR when performance was outside the bandwidth. A Control group received KR after every trial. A transfer test was run 10 min. later with 10 more trials and the target 3.0 m away, with no KR. Analyses showed that narrow KR bandwidth was associated with better learning of real world tasks.
研究了两种不同信息带宽的知识结果（KR）的效果。54 名大学生参与了实验。实验包括一个获取阶段，学生们练习尽可能准确地投掷飞镖，直到连续三次击中目标地板上 2.5 米远的特定区域。窄带宽组和宽带宽组在表现超出带宽时会收到 KR。对照组在每次试验后收到 KR。10 分钟后进行转移测试，进行 10 次额外的试验，目标距离 3.0 米，没有 KR。分析表明，窄 KR 带宽与现实世界任务的更好学习相关。
