- During a basketball game, an athlete tells herself she is not skilled enough to be a useful player on the team. She is feeling anxious that her teammates will be upset with her poor performance and this only causes her to play even worse. One of her teammates comes up to her and tells her to loosen up and focus on having fun during the game. This shifts the athleteβs mindset to a more positive excited state. This is an example of: β
A. Reversal Theory
B. Motive to achieve success
C. Self-controlled practice
A. Reversal Theory β
- You are supervising a gymnastics team during their practice. A gymnast is running through her new floor routine.

As she is doing her next jump connection, the coach yells out to tell her she needs to connect the jumps. What is this an example of?
A. Concurrent feedback which is good for long-term learning but not for performance
B. Concurrent feedback which is good for performance but not for long-term learning
C. Delayed feedback which is good for long-term learning but not for performance
B. Concurrent feedback which is good for performance but not for long-term learning β
- A novice weightlifter is learning how to execute the barbell clean. His coach directs him to begin by using a light PVC pipe to perform the movement. The coach has the athlete try 5 reps of just the first pull. The coach then tells the athlete to try the first pull with the transition. After this, the athlete is directed to do the first pull, transition, and second pull. What type of training does this represent? β
