2. motor programs are responsible for the larger chunks of the action via anticipatory control
3. fast processing of sensory inputs allows an on-line corrections and ability to attend to different stimulus
4. changes in performance are more subtle (changes in control)
true or false: process always indicates learning?
false not always
changes in performance do not necessarily indicate 'learning' as various contextual factors can affect one's behavioural output only TEMPORARILY
how can we tell if learning took place?
if there were retention trials or sometimes called transfer tasks
what is the definition of constant error?
the deviation with respect to AMOUNT AND DIRECTION of the result of performer's movement relative to some target value. it represents and average location of group of responses with respect to the desired target
how do we select validity of skill
by measure of constant error
what is the problem with constant error?
often the average error is much smaller than the error for any of the single responses
what is variable error?
inconsistency of results of several movements with respect to a performer's average constant error for the movement
what does variable error measure?
does not determine whether the subject was close to the target, but rather it represents the spread around its average
what is the process measures? ( selecting valid indicators of skill)
performance observations that indicate something about the quality of movement production: can be relatively unsophisticated ( ex. qualitative description of movement through eye-balling) or more precise ( EMG; kinematics)
what are the three internal structures involved in observable products of learning?
1. stimulus identification
2. response selection
3. response programming (parameterization)
what are the three aspects of observable products of learning: coordination
1. allows inferring the nature of emerging movement patterns and their stability (consistency)
2. coordination( ex. movement smoothness) can be inferred from spatial and/or relationship between joints/body segments
3. generally inferred from kinematic data
what are the two aspects of learning observable products of learning: control
1. allows inferring the adaptability of the system
2. movement control can be inferred from kinematic data showing changes in linear/ angular displacement, velocity, and acceleration of individual joints/body segments
what are the two aspects of observable products of learning: muscles used

who did a study on internal and external focus by instructed a group of people to balance on stabilometer?
Wulf et al, 2003
what is more beneficial external or internal focus?
external focus according to Wulf's study in 2003
what is narrow focus?
focus on only few sources of information at one time
what is broad focus?
focus on a wide range of information sources
is directing attention necessary for learn?
no, the amount and type of attentional focus is constrained by the task demands and skill level of participants (ex. with time instructors are encouraged to "fade away" the cues, hence to remove attentional cues from the learning process)
in open skills what should be the attentional focus?
external focus ( environment information)
in closed skills what should be the attentional focus?
internal focus ( may be more beneficial for learning)
what can lead to "paralysis by analysis"?
what is massing?
implies putting things together with little to no rest between periods of work
what is distributing?
implies spacing the periods of work apart with longer intervals of rest
what is distribution of practices effects on performance?
in a nutshell, use of short rest is more detrimental to performance as compared to longer rest periods
in discrete tasks what is better massed practice or distributed?
in discrete tasks, massed practice can be as "potent" as distributed
in continuous tasks, lack of rest between the bouts is detrimental to learning therefore is it massed or distribution practice?
distribution is better
Bourne & Archer 1956 conducted a study on what?
distribution and massing practices
according toe the Bourne & Archer study does it appear that in a long- run the affects of distributed type of practise remain permanent?
what are the three presentation techniques?
1. instruction (verbal)
what is demonstration also referred to as?
"model" leading to "observational learning"
what can be the 5 learned (inferred) from modeling?
1. movement strategies for success
2. spatial information about the desired action (distance)
3. temporal information (velocity)
4. relative timing (invariant feature of GMP)
5. error detection and correction techniques
when are models most useful?
earlier in practice when the GMP is acquired
true or false a model or a video is better for learning than verbal instruction alone?
true or false: use of imperfect model coupled with appropriate KR (augmented feedback) is better than observing the "correct" model alone
what is the real issue in modelling?
not the skill level of the model but rather what type of information is being demonstrated
what is guidance?
procedure used to assist/direct individuals through the task performance, either physically, verbally and/or visually to reduce errors to make performance more efficient
what is active guidance
type of guidance procedure where the performer still performers the actual action in order to learn the general movement pattern, this type of guidance provides the performer with motor as well as sensory benefits of moving the limbs/joints, this type of guidance is as little invasive/restrictive as possible
what is passive guidance
where the performer does not perform the actual action independently, but rather with physical assistance of the instructor/practitioner, this type of guidance often used during the initial stages of learning, this type is invasive and it takes away the sensory/perceptual experience that the performer can get from performing the action
conceptually speaking, passive guidance represents an example of ___ _____ in motor learning as the context in which the skill is practiced is drastically different from the real-life situation
what are the 4 forms of physical practice?
1. simulator practise
2. part practice
3. slow motion
4. practice for error detection
what is simulator practice?
use of training device that mimics real world activity/task (ex. driving simulator)
what are the 3 advantages to simulator practice?
1. it closely resembles the target skill/context
2. it may prevent injury when learning or relearning a skill
3. incorporated during the early stages of practice
what is part practice
approach used to learn a complex (ex. serial) skills in a more simplified form
what are the three forms of part practice?
what is fractionation
type of part practice in which one or more parts of complex skill is practiced separately (ex. arm movements in a dance)
what is segmentation
type of part practices in which one part of the target skill is practiced for a time then a second part is added to the first part and practiced together (after fractionization)
what is simplification
type of practice in which the complexity of some aspect of target skill is reduced (slowing the speed, open to close task), consistence with the notion of variable type of practice
when is part practice ineffective?
when practicing skills were the relationship between the sub-units is as important as learning of individual components
what is blocked practice?
practice sequence involving repetitions of the same task
what is random practice?
practice sequence involving different tasks in no particular order (consecutive repetition of same task is minimized or avoided)
what is the definition of concept of contextual interference
functional interference introduced into practice situation as a result of several different movement skills being practiced at the same time
true or false concept of contextual interference brings an upbeat effect on practice but is not beneficial to learning
false it has a depressing effect on practice but is beneficial
who did a study on contextual interference?
Shea & Morgan 1979
what is Shea & Morgan's study in 1979
contextual interference- using lights, they tested block and random learning
who did a practical implication of contextual interference study with batting?
Hall, Domingues & Cavazos
what are the two possible explanations for the counter-intuitive phenomena
1. elaboration hypothesis
2. forgetting/spacing hypotheses
who came up with elaboration hypothesis?
Shea & Zimny, 1983
what is the elaboration hypothesis?
random practice forces people to elaborate and discover the distinctiveness among skills results in
- more meaningful and long lasting internal representations in LTM
-more contrasts/comparison between tasks, leading to easier retrieval from STM
what is forgetting/spacing hypotheses
action pan is lost in STM and LTM once the movement is done so the process of programming has to occur all-over again in order to generate the next skill
true or false: random practice forces participants to repeatedly construct and bring up different plans once the task demands are altered. this leads to "action-plan-reconstruction" and "retrieval practice"
definition of GMP
program that defines a pattern of movements rather than a specific action
definition of parameters
variables which are changed/adapted by GMP
what is parameterization
act of assigning parameters to GMP to achieve a given task
what is the conceptual relevance of CI effect?
whereas in bloced type of practice one GMP is selected and used to generate the consecutive actions.. in random practice the performer has to go through the process of retrieval and "parameterization" of a GMP, each time a new skill has to be generated. This repeated burden of re-parameterization represents a "desirable difficult" in the practice situation
when is the random practice most effective?
- when the performer has the "general" idea of a movement ("motor stage" of learning process)
-when randomness (contextual interference) is presented gradually
what are the three concluding remarks about blocked practice
1. traditional way of teaching movement skills
2. leads to initial improvement due to stable and predictable environment
3. often it does not resemble the real-life context of the skill thus may not be beneficial to learning
what are the 3 concluding remarks about random practice?
1. appropriate when the performer has the "general" idea of movement
2. supports the notion of "specificity of practice hypothesis"
3. effective when randomness (contextual interference) is presented gradually
who said: " more variability during practice forces the creation of more general motor programs"
who said: " practice (learning) is a particular type of repetition without repetition"
true or false: a GMP allows a performer to control different versions of the same class of movement
what is invariant features of GMP
those aspects of the movement that remain the same across several similar, but not same attempts
what is variant features (surface parameters)
those aspects of the movement that change across several similar attempts of one task (ex. speed, amplitude, force)
what is constant practice?
rehearsal of only one variation of a given task during a session (kicking a ball at 7m/s)
what is varied or variable practice?
rehearsal of a number of variations of a task in one session (kicking a ball at 5,6,7 m/s)
make skills easier or harder
what are the two types of variation in setting and context?
what are three regulatory conditions
1. position on the court
2. trajectory of the ball
3. location/action of defender
what are two non-regulatory conditions?
when to implement variable type of practice?
wait till they have some idea of the movement, therefore during the motor stage/advanced beginner stage
what are 4 performance changes in motor stage/advanced beginner stage
1. more movement consistency
2. less self-talk
3. better anticipation/pre-programming
4. efficient self-monitoring of feedback and error correction
how much variability is appropriate?
difficult to predict as the degree of its effectiveness is likely context (task; skill level) specific
general rule of thumb for level of variability
changes in the constraints have to be done in a way that the integrity of the skill is maintained. hence, the general qualitative nature of the movement should remain the same.
how does variable type of practice help performance?
allows transfer/generalizability across novel arrangements of the same class of actions,
allows flexibility/adaptability of the system
how is this "generalizability" developed?
forcing people to reformat GMP
what is schema development: motor programs and parameters?
a schema theory of discrete motor skill learning
what is motor schema
a set of rules relating the various outcomes of the person's actions to the parameter values the person chooses to produce the outcome
what is the 3 roles of "feedback"
1. promotes efficient learning
2. ensures correct development of a skill
3. influences learner's motivation
what is intrinsic feedback sometimes called?
what is intrinsic feedback
sensory info that arises as a natural consequence of producing a movement, comes from sources outside the body (exteroception) or from within the body (proprioception)
what is extrinsic feedback also known as
what is extrinsic feedback
usually verbal or visual (demo) in nature, as opposed to intrinsic, it is provided (available) after the action was completed
what is KR
indicates the degree to which the performer achieved the desired movement outcome or environmental goal, in many real world tasks KR is redundant with intrinsic feedback
how long to give KR back?
what is KP
another type of extrinsic, or augmented feedback that provides info about the quality of the movement a performer has produced
what is referred to kinematic feedback KR or KP?
KP- feedback about the displacement, velocity, acceleration, or other aspects of the movement product
true or false: KP can focus on the positive, optimal aspects of performance, the emerging errors or both
what are the 4 properties of extrinsic feedback
1. positive reinforcement of correct behaviour (provides greater improvements in learning)
2. negative reinforcement that eliminates the incorrect aspect of the response/behaviour
3. intermittent reinforcement which does not "overload" the performer the performer
4. info feedback provides performers with error-correction info.. can be descriptive or prescriptive
what is descriptive feedback?
describes the errors a learner makes during the performance of a skill "not so good that time"
what is prescriptive feedback?
describes the errors a learner makes during the performance of a kill and suggests something the learner might do to correct the errors "next time shorten your backswing a few inches" " bend the elbow"
what are the two issues to consider before providing feedback?
-skill level of participants
- task complexity
is feedback necessary for learning to take place?
not always, as the essence of implicit learning (self guided learning) is to allow the participant to figure out on their own what works and what does not
what is program feedback?
feedback related to the acquisition of the basic pattern of the action (invariant features of GMP; temporal coupling between the relevant components)
what is parameter feedback
feedback related to the errors about the surface parameters of GMP, such as a amplitude, speed and force of the movement (ex. faster, slower, longer, higher, lower)
