describe motor control correct answers -started in psych
-new field: tech allowed for right answers, understand A&P
-penicillin & WWII jump started motor control: first time we could systematically peer into the
brain's function
motor control definition correct answers exploration of how the CNS produces purposeful,
coordinated movements in its interaction with the rest of the body and with the environment
create formal description, operating with exactly defined variables
two levels of motor control correct answers behavior level-function of the body
Neurological level-brain and CNS
three core issues of motor control correct answers serial order problem: sequence of movement
behavior, challenged that everything was a reflex. Ex. when you naturally turn when you lean to
one side in a car.. body fights this all the time
perceptual motor integration problem: both work continuously together
degrees of freedom problem: how we choose to move the way we do, tons of ways to do one
thing. remapping brain
Nikolai Bernstein correct answers movements are active goal directed processes not passive
conditioned responses
challenged Pavlov's dogs
identified degrees of freedom problem
Iron curtain prevented him from publishing in english
*father of motor control*
Degrees of freedom definition correct answers Bernstein
# of value in the final calculation of a stat that are free to vary
# of independent ways that a dynamic system can move. without violating any constraint
imposed upon it
DOF of motor system correct answers limbs joints, muscles, motor units
, end state comfort effect correct answers the preference of individuals to maximize comfortable
hand and arm positions at the completion of object transportation tasks rather than at the
beginning.
ex. pick up an empty cup.. you would flip it up as you picked it up to fill it with water.
serial position curve correct answers better recall for things at the end and beginning not middle
ex.commercials
primacy-intermediate-recency
relationship between memory and motor behavior (2) correct answers 1. end state comfort task
and a memory series of 11 letters
2. looking at whether a simpler motor task might bring back recency effect and a end state
comfort task
behavior wasn't effected by motor task
cognitive task effected motor task
motor and cognition intertwined, difficult to separate
motor learning definition correct answers the study of the processes involved in the acquisition
of a motor skill and the variables that inhibit the capability to perform a motor skill
is learning a permanent or temporary change correct answers usually permanent
is performance a permanent or temporary change correct answers temporary
motor development definition correct answers study of changes in human movement behavior
over the lifespan, the processes that under lie these changes and the factors that affect them
How do we know changes are happening (4) correct answers must have ability to accurately
describe behavior
must understand the different ways to describe behavior
must know typical movement in order to identify atypical
must have an ability to classify skill vs unskilled behavior
physical growth correct answers quantitative increase in size or body mass
physical maturation correct answers qualitative advance in biological makeup, cell, organ,
system advancement in biochemical composition
