The Interactive Effects of Task and External Feedback on Practice Performance and Learning

The interactions of task and external feedback on practice performance and learning were examined. While external feedback was consistently beneficial to performance during practice, regardless of the availability of feedback from the task, it was detrimental to learning when the task provided little feedback. External feedback benefited learning only when feedback was also available from the task. In addition, task feedback benefited learning, partially due to its effects on error detection and correction skills. Results suggest the importance of examining the simultaneous provision of feedback from different sources, studying the role of task feedback in learning, and more cleanly assessing learning to avoid confounding it with transient performance improvements.
