Concurrent and Delayed Feedback
Timing of when the feedback is given is extremely important in the learning of a skill. Some feedback is concurrent whereas other feedback may be withheld or delayed until after the athlete has finished their skill.
Concurrent feedback occurs at the same time as the execution of the skill and is relayed throughout the body by the proprioceptive sensors, which is internal feedback. However, this feedback can sometimes come from outside sources. For example, during a tennis serve, the server recognizes that their ball toss is off direction. This concurrent feedback allows the player to stop the serve and improve the toss, rather than continuing the serve and forced to make an error.
Delayed feedback occurs when there is a period of time between skill execution and feedback. An example of delayed feedback is waiting for the result of kicking a goal in soccer. The feedback (a successful or unsuccessful goal) is not provided until the ball either enters or misses the goal.
