Final answer:
Writing your signature bigger or faster than normal with your dominant hand would use the same Generalized Motor Program (GMP), whereas writing it with your non-dominant hand would not, due to a different set of motor skills and coordination.
Step-by-step explanation:
The concept being referred to in the question is Generalized Motor Programs (GMP). A Generalized Motor Program is a motor control theory that suggests there's a stored pattern of movement rather than a specific movement, which can be modified to produce a movement in different contexts while the underlying pattern remains the same.
When comparing the writing of your signature with your dominant hand to other scenarios, writing your signature bigger than normal or faster than normal would use the same GMP. This is because you are applying the same motor sequence with some adjustments in amplitude or speed, not fundamentally altering the movement pattern. However, writing with your non-dominant hand would likely not use the same GMP because it involves a different set of motor skills and neuromuscular coordination.
To answer the original question: Compared to writing your signature with your dominant hand, both writing your signature bigger than normal and writing your signature faster than normal would use the same GMP, but writing your signature with your non-dominant hand would not.
Hence, the options 1 and 2 would likely use the same GMP while option 3 would not. Option 4 is incorrect because it includes the non-dominant hand scenario.
