Motor learning Flashcards
what 4 things do skills require
- perception
- intention to move
- postural control
- coordination
what are the 3 stages in Fitts and Ponder model of motor learning
- cognitive stage
- associative stage
- autonomous stage
what is learning
result of permanent change, not observable, must monitor performance over a long period of time
what is performance
temporary, nonpermanent changes, observable
what are the 4 types of performance curves and what do they look like
- negatively accelerating
- linear
- positively accelerating
- s-shaped
what 3 things do performance curves measure
- to measure performance changes, compare performance on a pretest with a posttest
- to measure learning, a retention test must be administered following a break from practice (retention interval)
- to measure adaptability, perform a transfer test on a related motor skill following a retention interval
what are the three measures of retention
- absolute retention
- difference score - amount of loss in skill over the retention interval
- percentage score - amount of loss in skill over the retention interval relative to amount of improvement in original-learning score
5 types of transfers
- positive/negative
- general
- specific
- vertical
- lateral
when is general transfer used
can benefit different activities, contexts
when can specific transfer be used
only useful for adapting movement in the same context
what is lateral transfer
broad application of skills and knowledge to a range of task, all with similar levels of complexity
what is vertical transfer
applying what has been learnt to a simpler or harder task
what is motor learning
an ongoing dynamic process involving a search for and stabilisation of specific, functional movement patterns as each individual adapts to a variety of changing constraints
what’s the best age to learn a motor skill
around the age of pre-puberty when the neural plasticity is at its greatest is the best age to learn a new motor skill
what is a sensitive period
when the effect of experience on the brain is particularly strong
what is a critical period
when experience essential for normal development alters performance permanently
why do movement preferences exist
because of the structure of our bodies and how we control movement via the nervous system
what are intrinsic dynamics
the preferred states of the system given its current architecture and previous history of activity
what do sensitive periods allows
motor learning to be more rapid and easier
4 factors to cognitive approaches
- top down
- body is controlled (enslaved) by the Brian
- first information is processed and understood (input) then motor program is selected and released (output)
- mix of predictive processing and reflexive control of muscle
what are the 4 factors of direct perception (ecological psychology)
- energy transformations uniquely specific environmental properties and events
- no intermediate stages between perception and action
- animals sensory systems have evolved to pick up this information
- looming response in animals and human babies
what are the 4 factors of ecological dynamics
- bottom up
- individual-in-envionment is. complex dynamical system
- coordination emerges from many interacting constraints
- close interrelation between perceptual systems and motor systems
what is short term memory
stored for only 20-30 seconds unless rehearsed
