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
what is working memory
temporarily stores recently presented material
can retrieve information from long-term storage to influence current problem solving, decision making and movement production
what is long term memory
memories that are relatively permanent
what are the two ways a learner can modify technique
- explicit (conscious)
- implicit (sub-conscious)
4 factors of explicit ways to change technique
- instructions
- demonstration
- feedback
- manual guidance
4 factors of implicit ways to change technique
- manipulate constraints
- dual task
- analogy
- errorless learning
what are direct influences of constraints
change directly influences movement patterns
what are emergent influences of constraints
influence grows stronger with learning
what are indirect influences on constraints
more subtle influences on movement
what are decaying influences of constraints
influence degrades with learning
what view of human development does the bio ecological model have
holistic, longitudinal and contextual overview
what are the 4 nested subsystems of the bio ecological model
- microsystem
- mesosytem
- ecosystem
- macrosystem
what 3 things does learning within games help children to develop
- physical literacy
- identity
- belonging and community
what is TGFU teaching games for understanding
skills practice which is embedded within modified games
what is manipulating task constraints effective for
practitioners to guide learning
what is representative learning
practice content that should reflect the performance environment
what is task decomposition
break skills down into parts
what are two types of distributed practice
- massed
- distributed
what is massed practice
longer practice sessions and many practice trials
what might massed practice result in (3 things)
- fatigue
- reduced cognitive effort
- less time for memory consolidation
what is distributed practice
shorter practice sessions and fewer practice trials
what do type of practice do continuous skills benefit from
distributed
what is the basis of the challenge point framework
task difficulty should be modified to meet the demands of the task for the learner optimally
what is variability of practice
varying key parameters of the movement patterns used to perform a motor skill
what is the variability of practice hypothesis
variable practice = better retention and transfer
3 components of attention and what are they
- capacity - attentional capacity is not limitless
- selectivity - attention is selected either intentionally or incidentally
- focus - attention is wide or narrow and internal or external
what two factors are part of the single channel filter theories of attentional capacity
- tasks are accomplished in serial order
- the system can process only one task at a time
what are the two factors of selective attention
- several attention mechanisms each with limited capacity
- if tasks require a common mechanism they will be difficult to perform simultaneously
what is attention capacity critical to understand the importance of
automaticity of performance
what is efficient visual search
attention is guided to target item immediately making the rest of the scene irrelevant
what is extended visual span
pre-attentive processing of the sene before selective attention is directed to specific locations
what is selective attention
attention is guided by the information stored in long term memory
what are the four attentional styles
- internal borad
- internal narrow
- external broad
- external narrow
when is external focus most advantageous
when the task is complex/challenging
what is emotion
a mental state that arises spontaneously rather than through conscious effort and is often accompanied by physiological changes
