Movement Intelligence
Following factors affect development of movement intelligence:
– Starting at young age– Learning time– Instructor– Equipment– Progression
Sport Books Publisher 5
Starting the Learning Process at a Young Age
As early as the preschool years
Basic skills = basis for other activities– Walking, throwing, catching
Skill should be taught correctly the first time to avoid development of bad habits
Sport Books Publisher 6
Providing Sufficient Learning Time
Without physical experience, skills cannot be effectively learned and maintained
Sufficient time must be allotted for participating in PA’s that enhance movement skills
Sport Books Publisher 7
Being Taught By Qualified Instructors
Instructors, physical educators, and coaches must be properly trained and have experience with teaching PA
This means having trained physical educators fill such positions, rather than math or music teachers who do not have the necessary background
Sport Books Publisher 8
The Use of Quality Equipment
Safe, appropriate, and well maintained– e.g., scaled down equipment for
children• Lower basketball hoops• Smaller soccer nets• Lighter baseball bats
Effectiveness of teaching movement skills is directly related to the quality of equipment
Sport Books Publisher 9
Following the Right Progression Teaching skills in an organized manner that makes skills easier to
grasp and learn
Sport 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
Sport 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 the
skill
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
Sport Books Publisher 13
Associative or Stabilization Stage
Focused on performing and refining the skill
Concentration is directed towards smaller details (e.g., timing)
Performance: controlled and consistent
Rapid performance improvements (somewhat slower than fist stage)
Diminished self-talk
Sport Books Publisher 14
Autonomous or Application Stage Performance: automatic and very
proficient Attention demands:
Performance improvements:–Slow–Less obvious (e.g., reduced mental effort, improved style, reduced anxiety)
Sport 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 a result of the movement
Feedback is one of the strongest factors that controls the effectiveness of learning

Intrinsic Feedback Information that is provided as a natural
consequence of performing an action
Knowledge Knowledgeof performance of resultsArm extension Watching the when hitting the tennis ball landtennis ball in the
opponent’scourt
Sport Books Publisher 19
Extrinsic Feedback
Information that is provided to the learner by somebody else or some artificial means following a performance outcome
Provides information above and beyond what is naturally available to the learner (augmented feedback)
Can be controlled; when, how, how often…
Sport Books Publisher 20
Extrinsic Feedback cont’d 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 was
a little late,” etc.
Sport Books Publisher 21
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
Sport Books Publisher 22
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 minimize dependency have been identified
Sport Books Publisher 23
Faded Feedback
Benefit: teacher can tailor feedback to respect individual differences
Low Degree of skill High
High Gradually reduced (faded)
Feedback
Sport Books Publisher 24
Bandwidth Feedback
Benefits:1. Eventually faded feedback occurs2. Lack of feedback = positive reinforcement3. Movement consistency develops because learner is
not encouraged to change movement on each trial
Range of correctness

Summary Feedback
Benefits:1. Generates movement consistency
2. Avoids overloading the learner

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 resultsPrecise 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 more beneficial
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
Sport Books Publisher 33
Positive Transfer
e.g., Practicing drills and lead-up games with strong (positive) transfer to the actual game
Learning can be positively transferred from practice to game situation when drills are similar in nature to the criterion task
Sport Books Publisher 34
Negative Transfer
Not common
Activities that may negatively transfer to the criterion task need to be avoided when performance is critical
e.g., playing mini-golf before golf tournament
Sport Books Publisher 35
Factors Affecting Transfer
Positive Transfer Example
Negative Transfer Example
Movement Response/Patterns
e.g., tennis & badminton
RacquetsNetSimilar shot variations
Ball vs. birdie
Psychomotor Demands
e.g., rowing, kayaking, & canoeing
WaterDynamic balanceCoordination
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
Sport Books Publisher 36
Near Transfer
Desired when the learning goal is a task that is relatively similar to the training task
Transfer of learning is specific and closely approximates the ultimate situation
e.g., practicing various plays before a volleyball tournament
Sport Books Publisher 37
Far Transfer
Desired when interested in developing more general capabilities for a variety of skills
Occurs from one task to another very different task
Best applies when beginning to learn a skill e.g.,
overhand throw baseball throw, football throw, tennis serve, volleyball
spike…
Sport Books Publisher 38
Transfer Strategies
Training machines and stimulators Whole vs. part practice Lead-up activities and drills Mental rehearsal
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
Sport Books Publisher 40
Whole vs. part practice
Part practice– Practicing independent
components of motor skill– Eventually, units of a task should
transfer to the task as a whole– e.g., gymnastics routine
Whole practice– Practicing skill as a whole– e.g., golf swing
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 the actions of the next part (i.e., independent)
Sport Books Publisher 42
Whole Practice
Used with discrete tasks of short duration where components interact intensely
Practicing individual components would change the essence of the skill
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
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
Sport Books Publisher 45
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 mental rehearsal 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 supplementsupplement to physical practice
Sport Books Publisher 46
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 refine their skills
one at a time
- important early in practice when correct habits should be learned
b) Random Practice - ordering of tasks is randomized in a way that tasks from different
classes are mixed throughout the practice period
- random practice is very effective once a skill has become more developed
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
Sport Books Publisher 48
Grouping for Practice
Designed to make learning suitable for everyone involved
Should be based on the learners’ skill levels, rather than a subjective determination of their underlying abilities
Other factors, such as maturity level, previous experience, and level of physical fitness need to be considered
Sport Books Publisher 49
Effects of Motivation on Learning Until the learner has been motivated, effective learning is
not likely to occur An instructor plays an important role in motivating his
students (encouraging learners to set goals, providing excellent demonstrations, or using visual aids)
It’s a Fact !: She who is motivated makes more of an effort 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 responses that are not rewarded or punished
