Week 2 Flashcards
Motor learning
-a set of processes associated with practice or experience that leads to a relatively permanent change in capability for movement
Motor control
-an area of study dealing with the understanding of the neural, physical, and behavioural aspects of movement
Discrete skill
-defined start and end
Continuous skill
-no discrete start and end to the movement
Open movement
-influence of environmental factors
Closed movement
-no influence of environmental factors
Fine movement
-uses smaller muscle groups
Gross movement
-uses more compound movements
-large muscle groups
Considerations for measurement
-objectivity
-reliability
-validity
Constant error
-average error in the response
-sign gives direction of error
-measure of accuracy
Constant error limitations
-may not be valid
-sucesptible to directional variability (errors can cancel out)
Variable error
-how consistent is their shot
-does not depend on whether the performer was close to the target
Total variability (RMSE)
-measure of overall error
-similar to variable error but with reference to the target position
Absolute error
-used when direction of miss does not matter
Absolute constant error
-transformation of constant error that removes the sign of constant error
-used as a way to summarize group results that may be biased differently
Reaction time
-traditionally used as a proxy for cognitive function
-measure of the time from arrival of a stimulus to the beginning of the response
Premotor reaction time
-no muscle activity
Motor reaction time
-onset of muscle activity
Total response time
-reaction time + motor time
Motor time
-full muscle activity
What do correlations measure in reaction time
-direction and strength
Indirect way of measuring capability in a motor task
-dual cognitive task
