InIntro - Chap. 1 Flashcards
What is motor behaviour
the over, observable production of skilled movement
what are the 3 branches of motor behaviour
motor control (performance)
motor learning
motor development
what is motor learning
conditions of practice, how to provide feedback and how learning changes over time
what is motor development
how maturation influences our motor learning across the lifespan
what is the best practice for teaching curling to children and why
use rock of same weight but on shorter ice, eventually use longer sheet of ice
-builds understanding of how much force is required to push rock and this is more easily transfered to longer sheet of ice rather than using a lighter rock
in relation to motor control, what is similiar in medical procedures and sports
develop the necessary motor skills to be quick and accurate
what are the 3 classes of movement
reflexive (spontaneous)
learned
skilled
what makes a reflex
direct relation between stimulus and respons
-1:1 ratio
as a child, reflexes are more what
random
when are reflexes most apparent in our lives
first 6 months of life
what are skilled movements
things that one might be interested in, not everyone learns
what are the 4 aspects a skilled performer has
-benefited (or learned ) from their experiences
-learned what features of their environment they should attend to
-learned what to ignore
-learned to perform a behaviour not otherwise capable of
what is the key thing about motor skills
PRACTICE to achieve the skill
difference between movements and skills
skill: a particular set of limb movements combined to achieve a goal
movements: how limb moves through space
definition of motor skill
ability to bring about some end result with maximum certainty and minimum outlay of every, or of time and energy
what is defining skills
what are the key ingredients needed to make an action a skill
what are components of sills
what does a performer need to do to perform a motor skill
what is classification of skill
what makes a motor skill easy or hard
what are the 4 aspects that define a skill
-need environmental goal (motor outlet)
-ability to achieve goal with certainty and consistently
-minimizes energy consumption, physical and psychological
-minimum time
what are the 3 components of skills a performer needs to know
-what to do (the steps)
-when and where to do it
-how to do it (and be able to do it)
what are the 2 classifications of motor skill based on size of primary musculature
gross and fine motor skills
what are the 2 classifications of motor skills when it comes to the environment
open and closed skill
what is an open skill and give an example
a skill that is done in an environment that is always changing
-has some control but need to adapt to the environment
ex: soccer
what is a closed skill and give and example
environment is consistent and predictable
-you get to determine when to make the shot
ex: archery
what are the 3 classifications of motor skills when it comes to movement type
discrete, serial and continuous skill
what is a discrete skill and give example
skill containing a single unit of activity with a definite beginning and end
-taking a shot at a target
what is a serial skill
skills with 2 or more actions linked together
-series of discrete skills
what is a continuous skill and give example
a skill that has no apperant beginning or end
-swimming, cross country skiing
what are the 3 ways to measure discrete skills
absolute error
constant error
variable error
what classification of motor skill do we base ourselves on to measure movements
movement type
-discrete, serial, continuous
what is absolute error
tells us about the overall magnitude of error
(difference between measured or inferred value and the actual value of a quantity
what does absolute error not take into consideration
any details regarding the importance of the error
-direction, length, time etc.
what does constant error measure
performance bias
-whether one shoots more to one direction for example, or tends to throw too light etc.
what does constant variable measure
performance consistency
-the variability and realiability of ones performance
what type of equation is used to calculate variable error
standard deviation
how to calculate constant error
find average
-add all values and divide by the amount of values there are
how to calculate absolute error
find constant error (average)
-disregard the negative sign if it is, will always be positive
what is used to measure continuous movement and how does it work
root mean squared error
-calculates area between the desired pathway and the actual pathway
root mean squared error represents what when measuring movement
bias and consistency
