Questions And Correct Answers
Effective target width is a measure of __________.a) speed b) timing d) accuracy d) amplitude -
answer✔✔practice
what control system sends commands to the effector without receiving feed back and is used for
rapid, discrete movements? - answer✔✔Open-Loop control
evidence for _________ ________________ includes, electromyography (EMG),reaction time
(RT), and deafferentation. - answer✔✔motor programing
The motor program fails to explain ? - answer✔✔Novel tasks and storage problems
____________ is a centrally located control mechanism that produces genetic, repetitive actions;
it is similar to a motor program and triggered by some stimulus and seems to use patterns for
activation. - answer✔✔A central pattern generator
____________ theory suggests that there is a stored pattern of movement instead of a specific
movement. It allows flexibility in modifying the generalized program to produce various patterns
to meet the demands of the task. - answer✔✔Generalized motor program
_____________ is a surgical procedure in which a bundle of nerves is severed and results in the
prevention of nerve impulses reaching the spinal cord; animal experiments using this surgery
provide evidence for motor programs. - answer✔✔Deafferentation
Fitts' Law states that __________ is linearly related to index of difficulty (ID). -
answer✔✔Movement time (MT)
Effective target width is a measure of __________. - answer✔✔accuracy

____________ is accuracy expressed as the amount of spread or inconsistency of the movement
end points about the target area. - answer✔✔effective target width
When the timing of performance of a rapid movement is important,__________ is the type of
accuracy required - answer✔✔temporal accuracy
When a person attempts to produce the same force on repeated trials, __________ is thought to
be caused by relatively noisy processes that convert central nervous system impulses into
activation of muscle motor units.
a) stability
b) variability
c) auditory distraction
d) timing consistency - answer✔✔b) variability
