    Movement Intelligence

    Following factors affect development ofmovement intelligence:

    Starting at young age

    Learning time

    Instructor Equipment

    Progression

    Starting the Learning Process at a

    Young Age As early as the preschool

    years

    Basic skills = basis for otheractivities Walking, throwing, catching

    Skill should be taughtcorrectly the first time toavoid development of badhabits

    Providing Sufficient Learning

    Time Without physical experience,

    skills cannot be effectively

    learned and maintained

    Sufficient time must be allotted

    for participating in PAs thatenhance movement skills

  • 7/30/2019 Motor Skills Learning and Acquisition Processes

    Being Taught By Qualified

    Instructors Instructors, physical

    educators, and coaches mustbe properly trained and have

    experience with teaching PA

    This means having trainedphysical educators fill such

    positions, rather than math ormusic teachers who do nothave the necessarybackground

    The Use of Quality Equipment

    Safe, appropriate, and wellmaintained e.g., scaled down equipment for

    children Lower basketball hoops

    Smaller soccer nets

    Lighter baseball bats

    Effectiveness of teachingmovement skills is directlyrelated to the quality ofequipment

    Stages of Learning a Skill

  • 7/30/2019 Motor Skills Learning and Acquisition Processes

    11/49Sport Books Publisher 11

    Three general stages of motor learning

    have been identified

    Each stage consists of:

    Changes that occur as motor learning takes

    place

    Important features unique to each stage

  • 7/30/2019 Motor Skills Learning and Acquisition Processes

    12/49Sport Books Publisher 12

    Cognitive or Acquisition Stage

    Begins when task first introduced

    Learner cognitively determines:

    What the particular skill involves

    Performance goals required to perform theskill

    Instructions:

    Are verbally transmitted (verbal stage)

    Serve to convey the general concept of the

    skill

    Self-talk and verbal reminders facilitate

    learning

    Performance: slow, jerky, and awkward

  • 7/30/2019 Motor Skills Learning and Acquisition Processes

    13/49Sport Books Publisher 13

    Associative or Stabilization Stage

    Focused on performing andrefining the skill

    Concentration is directedtowards smaller details (e.g.,timing)

    Performance: controlled andconsistent

    Rapid performanceimprovements (somewhatslower than fist stage)

    Diminished self-talk

    14/49Sport Books Publisher 14

    Autonomous or Application Stage

    Performance: automatic and veryproficient

    Attention demands:

    Performance improvements:SlowLess obvious (e.g., reduced mentaleffort, improved style, reduced anxiety)

    Feedback for Skill Learning

  • 7/30/2019 Motor Skills Learning and Acquisition Processes

    16/49Sport Books Publisher 16

    Information feedback: the information

    that occurs as a result of a movement

    Some information is received during the

    movement and some is provided as aresult of the movement

    Feedback is one of the strongest factorsthat controls the effectiveness oflearning

    Intrinsic Feedback

    Information that is provided as a naturalconsequence of performing an action

    Knowledge Knowledge

    of performance of results

    Extrinsic Feedback

    Information that is providedto the learner by somebodyelse or some artificial means following aperformance outcome

    Provides information above and beyond

    what is naturally available to the learner(augmented feedback)

    Can be controlled; when, how, how often

    Extrinsic Feedback contd

    Knowledge of results Information about the degree of success

    Not effective when outcome is obvious

    Important when outcome is less obvious

    Knowledge of performance Information about the execution of a completed

    movement

    Example: took your eye off the ball, swing wasa little late, etc.

    Motivational Properties of

    Feedback Extrinsic feedback serves to motivate the

    learner

    Error correction Therefore, a skilled instructor should be able

    to reinforce correct actions as well as point

    out errors

    Feedback Can be a Crutch

    Providing feedback continuously for a

    long period of time can lead to

    dependency Occasional feedback tends to enhance

    learning

    Various types of feedback that minimizedependency have been identified

    How Much Feedback is Necessary?

    Novel tasks

    Processing capacity can be easily

    overloaded Intense but selective instruction

    One important piece of information

    feedback at a time

    Sport Books Publisher 28

    How Precise Should Feedback Be?

    Descriptive (general) feedback

    Indicates something you did, right or wrong

    e.g., there was no follow through Prescriptive (precise) feedback

    Provides you with precise correction statements

    about how to improve your movements

    e.g., snap your wrist more on the follow through

    Precise feedback generates far better results

    What is the Best Timing for Information

    Feedback?

    Short-term memory is very

    susceptible to loss

    Generally, the greater the delay of

    information provision the less effect the

    given information has

    Therefore, immediate feedback is morebeneficial

    Transfer of Motor Learning

  • 7/30/2019 Motor Skills Learning and Acquisition Processes

    32/49

    Sport Books Publisher 32

    Transfer of learning between two tasks

    generally increases as the similarity

    between them increases

    Types of Transfer:Positive vs. negative

    Near vs. far

  • 7/30/2019 Motor Skills Learning and Acquisition Processes

    33/49

    Sport Books Publisher 33

    Positive Transfer

    e.g., Practicing drills and lead-up gameswith strong (positive) transfer to the

    actual game

    Learning can be positively transferredfrom practice to game situation whendrills are similar in nature to the criteriontask

  • 7/30/2019 Motor Skills Learning and Acquisition Processes

    34/49

    Sport Books Publisher 34

    Negative Transfer

    Not common

    Activities that may negatively transfer tothe criterion task need to be avoidedwhen performance is critical

    e.g., playing mini-golf before golftournament

    Factors Affecting Positive Transfer Negative Transfer

  • 7/30/2019 Motor Skills Learning and Acquisition Processes

    Sport Books Publisher 35

    Factors Affecting

    Transfer

    Positive Transfer

    Example

    Negative Transfer

    Example

    Movement

    Response/Patterns

    e.g., tennis & badminton

    Racquets

    Net

    Similar shot variations

    Ball vs. birdie

    Psychomotor Demands

    e.g., rowing, kayaking, &

    canoeing

    Water

    Dynamic balance

    Coordination

    Boat size and level of

    balance

    Cognitive Demands

    e.g., basketball & handball

    Game purpose Travel on the court

    Biomotor Demands

    e.g., sprint & long jump

    Explosive power No take off and jump in

    sprinting

    Psychological Demands Narrow focus of attention

    in archery and darts

    Shifting attention in

    hockey vs. judo and karate

    36/49

    Sport Books Publisher 36

    Near Transfer

    Desired when the learning goal is a taskthat is relatively similar to the training

    task Transfer of learning is specific and

    closely approximates the ultimatesituation

    e.g., practicing various plays before avolleyball tournament

  • 7/30/2019 Motor Skills Learning and Acquisition Processes

    37/49

    Sport Books Publisher 37

    Far Transfer

    Desired when interested in developing moregeneral capabilities for a variety of skills

    Occurs from one task to another very differenttask

    Best applies when beginning to learn a skill

    e.g.,

    overhand throw baseball throw, football throw,tennis serve, volleyball spike

    Transfer Strategies

    Training machines and stimulators

    Whole vs. part practice

    Lead-up activities and drills Mental rehearsal

  • 7/30/2019 Motor Skills Learning and Acquisition Processes

    39/49

    Sport Books Publisher 39

    Training Machines and Simulators

    Closely mimic features of real-world task

    Goal = positive transfer of learning from

    simulator to the target skill

    Effectiveness depends on the ability to

    simulate motor as well as perceptual,

    conceptual, and biomotor elements

  • 7/30/2019 Motor Skills Learning and Acquisition Processes

    40/49

    Sport Books Publisher 40

    Whole vs. part practice

    Part practice Practicing independent

    components of motor skill

    Eventually, units of a task shouldtransfer to the task as a whole

    e.g., gymnastics routine

    Whole practice Practicing skill as a whole

    e.g., golf swing

  • 7/30/2019 Motor Skills Learning and Acquisition Processes

    41/49

    Sport Books Publisher 41

    Part Practice

    Effective for tasks serial in

    nature and relatively long

    duration

    Effective as long as the

    actions of one part do not

    interact strongly with theactions of the next part (i.e.,

    independent)

  • 7/30/2019 Motor Skills Learning and Acquisition Processes

    42/49

    Sport Books Publisher 42

    Whole Practice

    Used with discrete tasks

    of short duration where

    components interactintensely

    Practicing individual

    components wouldchange the essence of

    the skill

  • 7/30/2019 Motor Skills Learning and Acquisition Processes

    43/49

    Sport Books Publisher 43

    Progressive Part Practice

    Used to avoid transfer problems due to high

    levels of interaction among task components

    Effective for any sequential action; e.g.,

    tennis serve

  • 7/30/2019 Motor Skills Learning and Acquisition Processes

    44/49

    Sport Books Publisher 44

    Lead-up Activities and Drills

    1. Transfer to another target sporting activity

    e.g., passing, shooting, dribbling, and faking

    drills for soccer

    2. Improvement of basic abilities

    Quickening, balancing, perceptual exercises,

    etc.

    e.g., perceptual motor training

    Mental Rehearsal

    The process associated with mentally

    rehearsing the performance of a skill in

    the absence of any overt physical

    movement

    Evidence has demonstrated that mentalrehearsal generates positively

    transferable motor learning

    Involves constructing model situations

    and going through the motions of what

    you will do later

    Especially beneficial for injured athletes

    It is a supplement to physical practice

    Designing Effective Practice

    Conditions of Practice:

    a) Blocked Practice- a given task is practiced on many consecutive trials before

    setting about the next task- enables the learners to correct specific problems and refinetheir skills one at a time

    - important early in practice when correct habits should belearned

    b) Random Practice- ordering of tasks is randomized in a way that tasks fromdifferent classes are mixed throughout the practice period

    - random practice is very effective once a skill has becomemore developed

  • 7/30/2019 Motor Skills Learning and Acquisition Processes

    47/49

    Sport Books Publisher 47

    Massed Versus Distributed Practice

    a)Massed Practice-a schedule in which the amount of rest between practice trials is short

    relative to the trial length

    -eg. 5 sec of rest for a practice trial lasting 60 secs.

    b)Distributed Practice-practice that allows for more rest between trials relative to the trial length

    -the rest period may last as long as the trial itself

    Reducing the amount of rest between trials will also reduce the amount of

    time the body and central nervous system have to recover from physical

    and mental fatigue

    There is no single optimal practice-rest ratio for all learning tasks

    48/49

    Sport Books Publisher 48

    Grouping for Practice

    Designed to make learning suitable foreveryone involved

    Should be based on the learners skilllevels, rather than a subjectivedetermination of their underlyingabilities

    Other factors, such as maturity level,previous experience, and level ofphysical fitness need to be considered

  • 7/30/2019 Motor Skills Learning and Acquisition Processes

    49/49

    Effects of Motivation on Learning

    Until the learner has been motivated, effectivelearning is not likely to occur

    An instructor plays an important role in motivating hisstudents (encouraging learners to set goals,providing excellent demonstrations, or using visual

    aids)

    Its a Fact !: She who is motivated makes more of aneffort during practice, can practice for longer periods

    of time, and learns more in the end The Law of Effect: Organisms tend to repeat

    responses that are rewarded and to avoid responsesthat are not rewarded or punished
