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
The major roles of open-loop organizations in motor programs include all of the following except
Answers:
(A) define and issue commands to the musculature
(B)organize degrees of freedom of the muscles and joints into a single unit
(C)prevent postural adjustments in preparation for action

accuracy required - ANSWER:temporal accuracy

caused by relatively noisy processes that convert central nervous system impulses into activation of
muscle motor units.
