Abstract
Systems now may collect almost unlimited amounts of data on performance during learning. However, it is critical to ensure appropriate data are presented properly to the human to aid learning of a system. At the present time, extensive literature exists on training, but there is no agreed upon method of choosing exactly the data to present as feedback during training. This uncertainty is due to the lack of underlying principles for making feedback effective. This paper presents a formulation of feedback principles based on an understanding of the processing demands on the human operator. We explain how variables such as amount of structure and support in feedback interact with the human operator and the task to be learned. With this knowledge, designers may choose suitable feedback for training.
