Q 3Q 3
Consider the following performance situation: You are a basketball player guarding an opponent who has the ball. You know that about 80% of the time in this situation the player will move to your right and take a shot. So, you prepare to move in that direction. But, unexpectedly the player moves to your left. Which of the following describes your RT in this situation?
A) RT will be faster than if you had not prepared to move to the right
B) RT will be slower than if you had not prepared to move to the right
C) RT will be the same as if you had not prepared to move to the right
D) It is not possible to predict RT without more information about the situation

Q 5Q 5
If you need to perform a fast sequence of 3 movements, how will your RT for initiating this movement sequence compare to your RT for initiating a sequence of 6 movements? The RT for the 3 movements will be:
A) Faster than for the 6 movements
B) Slower than for the 6 movements
C) The same for both movement sequences
D) RT cannot be measured in these movement situations
