Which of the following would demonstrate the finding that some aspects of motor learning are independent of the specific effectors used to perform an action?
A)Right-handed pitchers have great difficulty in throwing a baseball accurately with the left hand.
B)Actions such as the backhand stroke in tennis require the coordination of a sequence of separate movements.
C)All cyclists tend to use the same set of effectors in riding, regardless of the specific age at which they learned to ride a bicycle.
D)One's signature looks very similar regardless of whether one uses the left or the right hand to produce it.

Question

The fact that one's signature looks very similar regardless of which hand is used to produce it demonstrates that there are certain aspects of motor learning that are independent of the specific effectors used. This suggests that there is a level of generalization involved in the learning of the motor skill of signature production that can be applied across different effectors (i.e., the left or right hand). Choices A, B, and C all deal with specific examples of motor learning that are highly dependent on the effector used to perform the action, and are not relevant to this finding.
